Vehicle body self-adjusting all-terrain off-road vehicle chassis

Abstract

A vehicle body self-adjusting all-terrain off-road vehicle chassis belongs to the technical field of automobile manufacturing and solves the problems of poor passing capacity and poor shock-absorbing performance of an existing chassis. The vehicle body self-adjusting all-terrain off-road vehicle chassis comprises a frame and is characterized in that the front end of the frame is connected with the middle portion of a front axle through a front bearing shaft, the back end of the frame is connected with the middle portion of a rear axle through a rear bearing shaft, the front end of the frame is further connected with the front axle through two vehicle body adjusting hydraulic cylinders which are symmetrically arranged, the back end of the frame is connected with the rear axle also through two symmetrically-arranged vehicle body adjusting hydraulic cylinders, and the two vehicle body adjusting hydraulic cylinders on the same side are connected through a hydraulic pipe. The vehicle body self-adjusting all-terrain off-road vehicle chassis is suitable for uneven ground, has good passing capacity and good shock-absorbing performance, and enables people who drive and ride for a long time to be more comfortable due to the fact that the lifting and descending of a vehicle body is only about half the lifting and descending of wheels, namely, the bumping degree is half the bumping degree of an existing automobile.

Description

Technical field: [0001] The invention relates to the technical field of automobile manufacturing, in particular to a body self-adjusting all-terrain off-road vehicle chassis. Background technique: [0002] Existing off-road vehicles, when traveling through mountains, canyons, deserts, and rainforest areas, if they drive on a road with a large difference in height, the wheels will slip due to uneven weight, or even hang in the air, thereby reducing the driving force of the wheels, and even The loss of propulsion greatly reduces the passing ability of the vehicle, and makes the driver and passengers feel very bumpy and uncomfortable. The suspension system plays a key role in improving vehicle performance due to uneven road surfaces. [0003] Suspension system is a general term for all force-transmitting connection devices between the frame of the car and the axle or wheels. Or the impact force of the car body, and attenuate the vibration caused by it, so as to ensure that th...

Problems solved by technology

[0006] However, the off-road vehicle chassis with this structure still has certain limitations, and it can only eliminate the bumpy feeling when the road level difference is not very large, and the vehicle's ability to overcome obstacles is not very high.

When the vehicle is in the field, it often encounters a situation where the road surface has a large difference in height, the vehicle still feels very bumpy, the swing of the vehicle body is still large, and the vehicle cannot even cross the obstacle at all.
