Suspensions for in-wheel motor driven vehicles

Abstract

The invention discloses a novel suspension suitable for a wheel side motor driving car and relates to the field of car engineering. The problems that an existing car suspension is connected with an axle, a large space at the bottom of a car is occupied, the suspension does not have a lifting function, and then car height adjusting cannot be achieved are solved. The novel suspension comprises a support assembly, an upper sleeve assembly and a lower sleeve assembly. The support assembly comprises a left fixing plate, a right fixing plate, an outer sleeve, an outer sleeve upper cover and an outer sleeve lower cover. The upper sleeve assembly comprises an inner upper sleeve upper cover, an inner upper sleeve, a first bearing and a second bearing. The lower sleeve assembly comprises an inner lower sleeve, an oil cylinder and a connecting flange disc. The suspension structure can go up and down, axle connecting is removed, the minimum ground clearance of the car can be adjusted, steering can be achieved, the suspension structure is good in sealing performance, car wading capacity is improved, and the suspension is suitable for off-road vehicles or engineering vehicles running on various rugged road surfaces. When the car runs on various rugged road surfaces, by adjusting front-back-left-right suspension lifting height, the car body posture is changed.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a novel suspension structure suitable for vehicles driven by wheel side motors. Background technique [0002] When earthquake relief, mine exploration, field operations, and border patrols require vehicles to cross rivers and transport personnel and materials on rough ground, this requires a vehicle with adjustable height and posture, a vehicle with a large minimum ground clearance, and off-road Very powerful special vehicles. Whether the suspension of the existing vehicle is independent suspension, non-independent suspension or oil-pneumatic suspension, the axle connection cannot be avoided, because a differential needs to be installed, which occupies a large space at the bottom of the vehicle. Although the tires on both sides of the vehicle with independent suspension The angles can be raised individually, but the angles are limited, and the height of the vehicle cannot be r...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the problem that the existing vehicle suspension is connected to the axle, occupies a relatively large space at the bottom of the vehicle, and the suspension does not have a lifting function, so that it is impossible to adjust the height of the vehicle. It provides a suspension suitable for vehicles driven by wheel motors shelf
