 较佳的，所述的启闭阀包括阀杆、摆杆以及推杆，阀杆上设有用于分别堵住第一制动排油口和第二制动排油口的凸台体，后缸体的下部设有滑孔，阀杆滑配合在滑孔内，滑孔内设有对阀杆施加弹力的回位弹簧，后缸体的后端设有摆孔，摆杆可自由转动安装在摆孔内，推杆穿过过渡活塞、第一制动活塞以及第二制动活塞并经密封件与它们滑配合，推杆的前端伸出过渡活塞的前端并设有挡块，挡块与过渡活塞之间设有推杆弹簧，摆杆的一端与推杆的后端相抵，另一端与阀杆的后端相抵。  Preferably, the opening and closing valve includes a valve stem, rocker and push rod, the stem has a boss for each block of the first brake discharge port and discharge port of the second brake body, the lower part of the rear cylinder is provided with slide holes, stem slide with the slide hole, the hole has a slide return spring for applying an elastic force of the stem, after the rear end of the cylinder with a hole swing, swing lever freely rotatably mounted in the swing hole, putt through the transition of the piston, the first brake and the second brake piston and piston seal with them by the snug fit, the front end of the push rod piston and extending the front end of the transition with a stopper the stopper is provided with a transition between the pusher piston spring, one end of the rear end of the push rod and the pendulum balance, the rear end of the other end of the stem even. 通过离合活塞所携带的让位体对推杆的作用而实现对启闭阀的通断控制。 Carried by the clutch piston plunger body gave way and achieve the effect of opening and closing the valve on-off control. 所以该集成总泵在对离合器控制时，让位体未对推杆产生推移作用，故启闭阀关闭，此时只有离合器活塞发生左移，而两制动活塞保持不动。 So that when the clutch master cylinder integrated control, giving way to the pusher body did not produce the passage effect, it is open and close the valve is closed, this time only occurrence clutch piston to the left, and the two brake pistons remain intact. 离合器活塞继续左移当让位体抵开阀杆，启闭阀处于开启状态时，开始产生制动控制作用，此时离合器活塞已将离合器工作腔的排油口关闭。 Clutch piston continues to give way to the left when the body arrived to open the valve stem, closing the valve is in the open state, it began to produce brake control action, then drain the clutch piston has a clutch working chamber mouth shut. 显然这种制动开启与关闭是由前位的离合器活塞来控制的，这种制动开启与关闭的时机由离合器活塞相对推杆的位置所决定的行程来确定的模式，故取名为“前导中心阀位控制式集成总泵”，也可称之为“前导式中心阀位控制集成总缸”。 Obviously, this brake is opened and closed by the clutch piston front position to control this brake opening and closing timing of the stroke of the piston relative to the push rod from the clutch position to determine the mode of decision, it is known as " Leading central valve position controlled integrated master cylinder ", also called" leading poppet valve position control integrated master cylinder. " 这种借助离合器工作腔的工作压力来对踏板某一位置需对制动器开始产生制动的作用模式，可以最大限度地保证踏板对离合器与制动器控制时，其踏板力与踏板行程不会超过人体标准的规定限值。 When this work by means of a clutch working chamber pressure required to start generating the brake pedal braking mode of action of a location, you can ensure maximum clutch pedal and brake control, the pedal force and the pedal stroke does not exceed human standard the prescribed limits.

 而启闭阀为电磁阀33时，需要用推杆24对电磁阀33的启闭开关34进行操作，推杆24的一端与离合活塞4连接，另一端穿过过渡活塞6、第一制动活塞7、以及第二制动活塞9并伸到后缸体20的外侧，电磁阀33第一制动排油口2和第二制动排油口3连接，电磁阀33的启闭开关34与推杆24的另一端对接。  The opening and closing valve when the solenoid valve 33, the need to use the push rod 24 pairs of solenoid valves 34 open and close the switch 33 is operated, the push rod 24 with one end connected to the clutch 4, the other end of the piston of the piston 6 through the transition, the first a brake piston Kai 7, and a second brake piston 9 and the outer cylinder 20 extends after the solenoid valve 33 of the first brake discharge port 2 and the second brake discharge port 3, and the solenoid valve 33 off switch 34 and the other end of the push rod 24 docking. 这样，在离合活塞4前后移动过程中，就可以根据离合活塞4移动的距离对电磁阀33进行控制。 Thus, the process of moving back and forth in the clutch piston 4, the electromagnetic valve 33 can be controlled according to the distance the clutch piston 4 to move.
 当然，启闭阀的结构还可以有多种变化，在此不再累述，凡在本发明独立权利要求的范围内，利用本发明的原理，采用各种常规变化均属于落在本发明的保护范围内。  Of course, the opening and closing valve structure also can have many variations, I am not tired, all within the scope of the independent claims of the present invention, the use of the principles of the present invention, the use of a variety of conventional changes belong fall the scope of the present invention.
 本发明使用时的基本工作过程如下：  The basic operation of the present invention is as follows:
⑴常态下离合总泵与制动总泵中的离合总泵、第一制动泵以及第二制动泵均与油壶I保持连通，第一制动排油口和第一制动排油口均处于常闭状态，离合排油口处于常开状态，或经过保压阀（图中未画出）处于常闭状态。 ⑴ Under normal clutch master cylinder and the brake master cylinder clutch master cylinder, first and second brake pump brake pump remain in communication with the oiler I, the first brake oil outlet and the first brake oil drain are in a normally closed port, discharge port of the clutch in a normally open state, or after pressure holding valve (not shown) in a normally closed state.
 首先，踏下“单控踏板”时就可以推动离合活塞左移，第一复位弹簧11被压缩，使离合工作腔5与油壶I之间的油路断开，离合工作腔5内的油压升高，使第一制动活塞7、第二制动活塞9跟随左移并关闭各缸与油壶I的常开通路，此时的阀杆22保持不动，由于凸台体30使第一制动排油口2和第二制动排油3 口处于常闭状态，使得第一制动工作缸8和第二制动工作缸10形成两个独立的封闭整体；  First, depress the "single-pedal control" when you can push the clutch piston to the left, the first return spring 11 is compressed, so I clutch between the working chamber 5 and the oiler oil line off the clutch working chamber 5 oil pressure inside increases, the first brake piston 7, a second brake piston 9 follows the left and off for each cylinder and the oiler I often open road, this time the stem 22 to remain intact, because the boss body 30 of the first brake discharge port 2 and the second brake drain 3 is normally closed state, so that the first brake cylinder 8 and the second brake cylinder 10 to form two separate closed whole;
⑵继续踏动踏板，第一制动工作缸8、第二制动工作缸10以及离合工作腔5内的油压均升高，但不足以推动第一制动活塞7和第二制动活塞9发生移动，从而完成离合器分离，此刻驾驶人员可进行换挡操作，或保持汽车的惯性行驶； ⑵ continue riding the brake pedal, a first brake cylinder 8, the second brake cylinder 10 and the clutch oil pressure within the working chamber 5 are increased, but not enough to push the first piston 7 and the second brake brake piston 9 from moving, thus completing the clutch, at the moment the driver can shift operations, or to keep coasting car;
⑶继续踩踏踏板，进入缓速控制，离合器强迫结合或所控制的缓速器开始工作，当离合活塞4前移至挡块28与让位体4. 2相碰，推杆24左移，带动摆杆23摆动并推动阀杆22移动，将第一制动排油口2和第二制动排油口3打开，开始对车辆进行制动，此时离合器活塞4已将离合器工作腔5的排油口14关闭，继续踏动踏板，离合活塞4与过渡活塞6相抵，第一制动活塞7和第二制动活塞9开始移动，阀杆22被推移动到将第一制动排油口2和第二制动排油口3打开到一定位置后，并且摆杆23上球端被推移至与摆孔27后壁相抵时，让位体4. 2开始后退移动，既保证阀杆22的位置，又能保证离合活塞4继续推动过渡活塞6移动，使第一制动泵和第二制动泵可以持续的对车辆进行制动。 ⑶ continue treading the pedal into the retarder control, combined with the clutch forced or controlled retarder to work, when the clutch piston moves to block 28 and block 4 before giving way body 4.2 collide, putting 24 left, drive 23 and push the pendulum swing stem 22 moves, the first brake discharge port 2 and the second brake discharge port 3 is opened, starting the vehicle brakes, then the clutch piston 4 has a clutch working chamber 5 discharge port 14 is closed, continue riding the brake pedal, clutch piston 4 and the transition balance piston 6, the first brake piston 7 and the second brake piston 9 begins to move, the stem 22 is pushed to move to the first brake oil drain After opening 2 and the second brake discharge port 3 is opened to a certain position, and swing on the ball end of the rod 23 is pushed to move with the swing hole 27 offset rear wall, giving way to move the body 4.2 began to recede, both to ensure the stem 22 position, but also to ensure that the clutch piston 4 to continue the transition of the piston 6 moves, the first and second brake pump brake pump can last for vehicle braking. 在松开踏板之后，在各个复位弹簧的作用下，集成总泵可以顺利的回复常态。 After the pedal is released, the return spring of the role of each, the master cylinder can be smoothly integrated response norm.
 本发明与车辆的离合系统、制动系统相结合，可以根据车况比较理想的实现从离合器分离，进入离合器强迫结合阶段实现挂车缓速，再进入行车减速，然后进入离合器分离阶段实现驻车制动或者紧急制动。  The clutch system of the present invention relates to a vehicle braking system combined can achieve more satisfactory from the clutch, clutch forced into the realization phase trailer combination retarder, and then enter the deceleration lane, and then entered the stage clutch implement according to the condition in brake or emergency brake.
 结合图4阐述，该集成总泵参照了目前现有的技术，在使用本发明时，可以在踏板与本发明集成总泵之间增设助力装置，如真空助力器31，可以保证在人体脚踏力的限值内有效提供对离合器的分离力与制动器的制动力。  Figure 4 illustrates the combination of the integrated cylinder reference to currently available technology, the use of the present invention, can be added between the pedal assisting device of the present invention, the integrated master cylinder, vacuum booster 31, can guarantee provide for effective separation force braking force clutch and brake pedal force within the human limits.
 此例可以实现离合器与制动器均由单一的踏板控制，更有利于人体操控上的动作习惯，即脚踏动作的连续性控制，详细地说就是：由离合器分离来保持惯性车速，到汽车的缓速控制，再到行车制动的连续性控制。  This example can be achieved by a single clutch and brake pedal controls, more conducive to action on the habits of human manipulation, that the continuity of the operation of the control pedal detail that is: to maintain the inertia of the clutch speed, to car retarder control, to the continuity of the service brake control.
 该集成总泵又名集成主缸所实现的二踏板布置方式，相对目前所使用的液力变矩器来实现的自动挡二踏板布置方式，前者比后者造价更低、加速起动更快。  The integration of the master cylinder, also known as integrated cylinder implemented two pedal arrangement, the torque converter relative currently used to achieve automatic two pedal arrangement, the cost of the former is lower than the latter, the acceleration start faster. 且液力变矩器虽然技术含量高，但相对结构复杂，体积与重量均较大，故障率也相对较高，故障成因也较复杂，维修费用也较高等缺陷。 Although the torque converter and high technical content, but relatively complex structure, size and weight are larger, the failure rate is relatively high, the cause of failures is also more complex, higher maintenance costs and other defects.
 由该集成总泵所实现的二踏板布置方式，通过对离合器强迫结合装置进行控制，不仅可以增加汽车的缓速控制功能，期间还可增设对汽车其它缓速器如：涡流缓速器、节气门缓速器等的控制功能，从而达到对制动器保护作用的目的，防止因制动控制过程未设缓速功能，直接对制动器的频繁使用，而致使其摩擦过热而发生制动失效的问题。  The integrated master cylinder achieved by a two-pedal arrangement, by forcing binding clutch means control, not only can increase the retarder control of the car, the car can be added, such as during other Retarder: Retarder device, such as a throttle retarder control functions, so as to achieve the purpose of the protective effect of the brake, to prevent the brake control process is not set retarder, direct frequent use of the brake, the friction caused it to overheat and brake failure occurred problems.
 结合图3进行阐述，该集成总泵是一种制动开启由离合器活塞行程的位控方式来控制的，虽然该总泵由一个踏板控制，但在工作时，不会产生'离合控制活塞'与'制动控制活塞'共同发生位移的现象，从而导致踏板行程过大而超出人体踏板行程的规定范围值，同时离合器控制活塞与制动器控制活塞为异径串联结构，所以不仅可以保证对离合器控制压力与制动器控制压力的各自的工作压力的需求不同，而且还可保证对离合器与制动器控制时，其踏板力也不会超过人体标准的规定值。  described in conjunction with Figure 3, the integrated brake master cylinder is an open position by the clutch piston stroke control mode controlled, although the master cylinder controlled by one pedal, but at work, does not produce 'clutch the control piston 'and' brake control piston 'common displacement phenomenon, leading to excessive pedal travel beyond a predetermined range of values of the pedal travel the body, while the clutch control piston and the control piston of the brake reducer tandem structure, it is possible not only to ensure the different needs of the clutch control pressure and brake pressure control pressure of their work, but also to ensure that when the clutch and brake control, the pedal force does not exceed a predetermined value of human standards. 具体的讲，同一个踏板力下，当踏板的位置低于Cl1分界位置时，踏板只控制离合器，即只是离合器工作腔发生压缩变形，但当踏板位置高于Cl1分界位置时，踏板对制动器产生控制作用，此时第一、第二制动腔依次发生压缩变形，而离合器工作腔则保持在离合器活塞与过渡活塞相抵的状态，不再发生其工作腔的变形。 Specifically, under the same pedal force, when the position of the pedal is less than Cl1 boundary position, the clutch pedal control only, ie just the clutch working chamber compression occurs, but when the pedal position higher than Cl1 boundary position, the brake pedal to generate control action, while the first and second brake chamber is sequentially compressed deformation, and the clutch working chamber is maintained at the clutch piston and piston offset transition state, the deformation of its working chamber no longer occur. 该特性曲线为非单一递增曲线，由于该曲线在Cl1分界位置的“跌落”特性，也就决定了踏板力不会超过人体标准的规定值这一要求。 The characteristic curve is non-monotonically increasing curve, as the curve in the "drop" feature Cl1 boundary location, will determine the pedal force does not exceed a predetermined value of human standards this requirement. 而且制动与离合工作腔各自独立的压缩变形，不仅可以保证其对应的工作腔的压力建压快，而且其踏板行程也是最短的。 And brake and clutch working chamber separate compression can not only ensure that the pressure of the working chamber of the corresponding pressure built fast, but it is also the shortest of the pedal stroke.
 采用由该集成总泵所实现的二踏板布置方式时，单控踏板与加速度踏板的联动控制作用，可实现汽车手动与自动挂档的更为方便的交替控制作用。  When using the integrated master cylinder achieved by a two-pedal arrangement, the role of a single control pedal linkage control the acceleration pedal, enabling hanging files more convenient alternate car manual and automatic control action. 如自动挂档的一个控制实例是：当踏下单控踏板使离合器分离后，再进一步踏下踏板在使离合器强迫结合的整个工作期间，此时汽车已处于缓速或行程制动状态，再踏下已被单控踏板切断燃油供给系统的加速度踏板时，驾驶员就可通过车身电脑的控制系统，可实现自动挂下一档的目的。 The automatic hanging files a control example is: when a single control pedal depressing the clutch after the separation, further depressing the clutch pedal in the entire period of forced combine work, this time has been in the car retarder braking or stroke, and then When depressing the pedal has been cut sheet acceleration pedal control the fuel supply system, the driver can control the computer system through the body, it can achieve the purpose of the next file automatically linked. 同样当驾驶员踏下单控踏板使离合器分离的整个期间，此时踏下已被单控踏板切断燃油供给系统的加速度踏板时，驾驶员同样可通过车身电脑的控制系统，可实现自动挂上一档的目的。 Similarly, when the driver depresses the single control pedal to clutch the entire period, then depress the control pedal when the sheets have been cut off the fuel supply system of the acceleration pedal, the driver is also available through body computer control system, automatic hang up a purpose document. 所以在踏下单控踏板时，再踏下已被单控踏板切断燃油供给系统的加速度踏板时，此时可对加速度踏板增设自动挂档的功能，以进一步完善该集成总泵对汽车的简化控制要求，或满足驾驶员对自动控制的一种需求。 So when riding under a single control pedal, then depress the pedal has been cut sheet acceleration pedal control the fuel supply system, in which case the acceleration pedal additional functionality can automatically linked files in order to further improve the integration of the master cylinder to simplify the control of the car requirements, or to meet a need for automatic driver control.
 采用由该集成总泵所实现的离合器与制动器一体化集成控制，可以集中使用一个或至少一个助力器装置，可以进一步减少整车成本，以进一步达到更佳的性能价格比，并进一步提高市场竞争力的要求。  The clutch and brakes are controlled by the Integration achieved the integration of the master cylinder can be concentrated using one or at least one booster device that can further reduce the cost of the vehicle, in order to achieve better cost performance further and further improve the market competitiveness requirements.
