Among the figure: the wheel erecting frame 3-car body 4 of 2 wheel stands of 1-wheel 2-contain-contain wheel erecting frame 5-unitary rotation actuator 6-axle 7-gear heart cover 8-sealing 9-heart cover bearing 10-variable wheel stand actuator 11-spindle bearing 12-driven wheel 13-axle axle sleeve 14-axle sealing 15-middle rotating part of 1 wheel stand
The specific embodiment
As shown in Figure 1, be mechanical schematic diagram of the present invention.3 wheels 1 are installed in the wheel erecting frame 2 that contains 2 wheel stands respectively and contain on the wheel erecting frame 4 of 1 wheel stand, the wheel erecting frame 2 that contains 2 wheel stands is installed on the same axis with the wheel erecting frame 4 that contains 1 wheel stand, and all can be around this rotation axis rotation.The angle α of two arms of the described wheel erecting frame 2 that contains 2 wheel stands is 120 degree, but this wheel erecting frame 2 rotates continuously with respect to the car body multi-turn; The wheel erecting frame 4 that contains 1 wheel stand and the rotation angle theta of 1 arm of the wheel erecting frame 2 that contains 2 wheel stands are arbitrarily angled in the 60-195 degree, as 60 degree, 120 degree, 195 degree.
As shown in Figure 2, be the structural representation of one embodiment of the invention.The wheel erecting frame 4 that contains the wheel erecting frame 2 of 2 wheel stands and contain 1 wheel stand is separately fixed at can be on the rotating part 15 that car body 3 centre of grations rotate.Three wheel 1 rectangular distributions, containing the wheel erecting frame 4 of 1 wheel stand and containing angle between two arms of wheel erecting frame 2 of 2 wheel stands is θ=120 °, satellite gear is in uniform state.At this moment, the satellite gear unitary rotation can significantly promote the travel carrying capacity and the obstacle climbing ability of vehicle.
As shown in Figure 3, be structural representation after Fig. 2 angle changes.Shown in Fig. 3 be that the wheel erecting frame 4 that contains 1 wheel stand rotates to and contain angle between 1 arm of wheel erecting frame 2 of 2 wheel stands is θ=195 °, and at this moment, satellite gear is converted to rounding state, thereby the height of celestial body car can be reduced.When the wheel erecting frame 4 that contains 1 wheel stand rotated to and to contain angle between 1 arm of wheel erecting frame 2 of 2 wheel stands be θ=60 °, the height of satellite gear reaches the highest, and was the highest thereby the height of celestial body car also is raised to.
As shown in Figure 4, the wheel erecting frame 2 that contains 2 wheel stands is installed on the gear heart cover 7, and the wheel erecting frame 4 that contains 1 wheel stand is installed on the axle 6; Gear heart cover 7 is supported in the installation cavity of car body 3 formation by heart cover bearing 9, and the gear heart overlaps 7 outer ends sealing arrangement 8, as skeleton type rubber seal, Type B rubber dust-proof seal ring, rotary shaft lip seal etc.; Axle 6 is supported in the inner chamber of gear heart cover 7, and axle 6 links to each other with variable wheel stand actuator 10 by the female splines of its inner end, and variable wheel stand actuator 10 is installed in the gear heart by bolt and overlaps on 7 inner ends; Unitary rotation actuator 5 is fixed on the car body 3, and driven wheel 12 is connected on the whole actuator 5, and with gear heart cover 7 on gear mesh, drive their by unitary rotation actuator 5 and rotate.
When variable wheel stand actuator 10 was locked, unitary rotation actuator 5 rotated and can order about wheel erecting frame 4 that contains 1 wheel stand and the wheel erecting frame 2 that contains 2 wheel stands and rotate around rotation axis simultaneously.
When 5 releases of unitary rotation actuator, variable wheel stand actuator 10 rotates and can make the wheel erecting frame 4 that contains 1 wheel stand lift or press down.Under the action of gravity that acts on the satellite gear centre of gration, two-wheeled remains ground connection, car load lifting or press down.
