Vehicle wheel suspension mechanism capable of lifting vehicle wheels

Abstract

The invention relates to a vehicle wheel suspension mechanism capable of lifting vehicle wheels. The vehicle wheel suspension mechanism comprises a longitudinal swing arm (1), a damper (2), a suspension frame (3) arranged outside a vehicle body, a slide rail (4) and a hydraulic cylinder (5). The vehicle wheel suspension mechanism is characterized in that the longitudinal swing arm (1) is hinged to one end of the damper (2), the other end of the damper (2) is hinged to the suspension frame (3), the suspension frame (3) is in linkage with a piston rod of the hydraulic cylinder (5), the suspension frame (3) is pushed and pulled by the hydraulic cylinder (5) to move in the slide rail (4), the axis of the slide rail (4) and the axis of the hydraulic cylinder (5) are arranged horizontally, when the hydraulic cylinder pushes and pulls the suspension frame (3) to move along the horizontal axis in the slide rail (4), the suspension frame (3) drives the longitudinal swing arm (1) through the damper (2) to swing around the own swing arm axis, then the wheels are driven to raise and fall, and namely the suspension height of the vehicle wheels is changed. The mechanism can further be used in series and can be used for crawler belt bearing wheels and other occasions where multiple vehicle wheels are arrayed adjacently.

Description

technical field [0001] The invention relates to a wheel suspension mechanism capable of raising and lowering the wheels, which belongs to the field of automobile manufacturing. Background technique [0002] The patent document "ZL00109897.7" provides the main structure of an all-road vehicle. This vehicle is an amphibious all-road vehicle with both wheels and tracks. The vehicle changes the walking mode of the vehicle by lifting the wheels and tracks. . [0003] This patent document provides three kinds of suspension mechanisms that can make the wheels or crawler tracks lift, but experiments show that there are many defects in these suspension mechanisms, mainly: most of the parts in the suspension mechanisms of wheels and crawler tracks are arranged in watertight Therefore, installation and maintenance are very inconvenient, especially for the suspension mechanism of the track load wheels. Because the number of track load wheels is large and they are arranged adjacent to e...

[0003] This patent document provides three kinds of suspension mechanisms that can make the wheels or crawler tracks lift, but experiments show that there are many defects in these suspension mechanisms, mainly: most of the parts in the suspension mechanisms of wheels and crawler tracks are arranged in watertight Therefore, installation and maintenance are very inconvenient, especially for the suspension mechanism of the track load wheels. Because the number of track load wheels is large and they are arranged adjacent to each other, the suspension mechanism can only be installed in place at the same time as the body is manufactured. Once sealed, it cannot be disassembled
