Hydraulic spring foldable retracting device for amphibious vehicle wheels

Abstract

The invention relates to a vehicle wheel retracting device, in particular to a hydraulic spring foldable retracting device for amphibious vehicle wheels. The device is a double-wishbone independent suspension, and comprises a wheel assembly (1), a pin shaft I (2), a wheel connection arm (3), a pin shaft II (4), an upper cross arm (5), a shock absorber (6), a pull rod assembly (7), a pin shaft III (8), a frame (9), a pin shaft IV (10), a pin shaft V (11), a hydraulic oil cylinder (12), a crank (13), a pin shaft VI (14), a pin shaft VII (15), a pin shaft VIII (16), a differential assembly (17), an internal universal transmission assembly (18), a drive shaft (19), a lower cross arm (20), a pin shaft IX (21) and an external universal transmission assembly (22). Compared with the prior art, the device has the advantages of large vehicle bottom clearance from the ground, simple structure, sensitive reaction and no influence on the vehicle bottom casing streamline, and is suitable for wheels of water and land amphibious vehicles.

Description

technical field [0001] The invention relates to a vehicle wheel retractable device, in particular to an amphibious vehicle wheel hydraulic spring folding retractable device. Background technique [0002] Existing amphibious vehicle wheel hydraulic retractable devices UK 2425511 and US 6945832 all use hydraulic cylinders as the power for shock absorption and wheel retraction. The ground clearance of the chassis is small, the passability is not good when driving on the road, and the travel of the wheels is not enough when driving on the water, which affects its driving speed on the water, cannot turn rapidly, and destroys the streamline of the vehicle's water surface, affecting the high-speed performance of the vehicle. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the existing technology, and provide a hydraulic spring folding and retracting device with good shock absorption effect, large chassis ground clearance,...
