Retracting-releasing device of amphibious vehicle wheel

Abstract

The invention discloses a wheel storing device of amphibious vehicles which belongs to the field of the storing devices of vehicle wheels. The device is an independent suspension fork with double cross arms and comprises a wheel assembly (1), an external universal driving assembly (2), a master pin (3), a first spherical hinge (4), an upper cross arm (5), a vehicle frame (6), an oscillating damper (7), a coil spring (8), sliding blocks (9), a connecting rod of a sliding block (10), a guide rail (11), a piston rod (12), a hydraulic cylinder (13), a crank connecting rod (14), braces (15), a compensating gear (16), an internal universal driving assembly (17), a driving shaft (18), a transverse stabilizer rod (19), a lower cross arm (20) and an upright post of the stabilizer rod (21). Compared with the prior art, the device has small occupying area, simple structure and flexible reaction, and is applicable to the amphibious vehicle wheels which can be used both in water and in land.

Description

technical field [0001] The invention relates to a wheel retracting device of an amphibious vehicle. Two pairs of wheels are retracted from a road mode to a water mode. Background technique [0002] The existing amphibious vehicle wheel retractable devices US5590617 and US4958584 both place the damping system above the upper cross arm, which will take up a lot of space, and the center of the car body will rise, which will cause the center of gravity to rise and reduce the stability during driving. Sexuality, the tendency to increase body roll. And the screw mandrel structure that US4958584 adopts is insensitive to speed when the wheel is retracted, and the wheel cannot be retracted and put down quickly. GB2425511A greatly changes the suspension of the original car, and the structure is more complicated, which will inevitably increase the manufacturing cost, and take up a lot of chassis space, and has the disadvantages of complex structure, insensitive response, and large spa...

Problems solved by technology

[0002] The existing amphibious vehicle wheel retractable devices US5590617 and US4958584 both place the damping system above the upper cross arm, which will take up a lot of space, and the center of the car body will rise, which will cause the center of gravity to rise and reduce the stability during driving. resistance, the tendency to increase body roll

Moreover, the screw structure adopted in US4958584 is not sensitive in speed when the wheels are retracted, and the wheels cannot be retracted and put down quickly.

GB2425511A has a lot of changes to the original car suspension, and the structure is more complicated, which will inevitably increase the manufacturing cost, and take up a lot of chassis space, and has the disadvantages of complex structure, insensitive response, and large space occupation.
