Embodiment 1

[0025] like figure 1 As shown, the large-load independent suspension for vehicles of the present invention is applied to a two-axle vehicle, wherein the number of the oil-pneumatic springs 1 is four, and there are two oil-pneumatic springs 1 on each side, and the two oil-pneumatic springs 1 on each side are One set, two oil-pneumatic springs 1 on each side are communicated through hydraulic pipelines. The hydraulic pipeline is connected with the height adjustment control part in the vehicle hydraulic system, and the height adjustment control part is connected with the high pressure oil circuit and the oil return circuit.

Embodiment 2

[0027] like figure 2 As shown, the large-load independent suspension for vehicles of the present invention is applied to a four-axle vehicle, wherein the number of said oil-pneumatic springs 1 is eight, and each side has four said oil-pneumatic springs 1, and the four oil-pneumatic springs 1 on each side are One group, four oil-pneumatic springs 1 on each side are communicated through hydraulic pipelines. The hydraulic pipeline is connected with the height adjustment control part in the vehicle hydraulic system, and the height adjustment control part is connected with the high pressure oil circuit and the oil return circuit.

Embodiment 3

[0029] like image 3 As shown, the large-load independent suspension for vehicles of the present invention is applied to a four-axle vehicle, wherein the number of said oil-pneumatic springs 1 is eight, and each side has four said oil-pneumatic springs 1, and each side has four oil-pneumatic springs 1 minute. There are two groups, each group has two oil-pneumatic springs 1, and the two oil-pneumatic springs 1 in each group are connected through hydraulic pipelines. The hydraulic pipeline is connected with the height adjustment control part in the vehicle hydraulic system, and the height adjustment control part is connected with the high pressure oil circuit and the oil return circuit.

Abstract

The invention discloses an automobile great-load independent suspension, and relates to a suspension system used for a chassis. The invention aims to provide the automobile great-load independent suspension which enables the chassis to be of good riding comfort, stability and controllability, driving safety and trafficability characteristic under any load. The automobile great-load independent suspension disclosed by the invention comprises hydro-pneumatic springs (1), the hydro-pneumatic springs are symmetrically arranged on two opposite sides of the chassis, the hydro-pneumatic springs on each side are divided into at least one group respectively, and the hydro-pneumatic springs in each group communicate through hydraulic pipelines.

Description

technical field [0001] The invention relates to the vehicle field, in particular to a suspension system for a vehicle chassis. Background technique [0002] Suspension is the general term for all force transmission connection devices between the frame (or load-bearing body) and the axle (or wheel) of a car. Its function is to transmit the force and torque acting between the wheel and the frame, and buffer the impact force transmitted from the uneven road to the frame or body, and reduce the vibration caused by it, so as to ensure that the car can run smoothly. Especially for special vehicles, the chassis requires high maneuverability and high off-road performance, so that the special vehicle chassis can have good ride comfort, handling stability, driving safety and passability under any load. Some vehicle suspensions cannot meet the above requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-loa...
