Oil-gas balanced suspension system and vehicle

Abstract

The invention discloses an oil-gas balanced suspension system and a vehicle, and belongs to the technical field of vehicle balanced suspensions. The vehicle comprises the oil-gas balance suspension system, and the first oil cylinder is installed on one side of an intermediate axle of the vehicle and comprises a first rodless cavity and a first rod cavity; the second oil cylinder is installed on one side of a rear axle of the vehicle, the first oil cylinder and the second oil cylinder are located on the same side, and the second oil cylinder comprises a second rodless cavity and a second rod cavity. One end of the first oil pipe is communicated with the first rodless cavity, and the other end is communicated with the second rodless cavity; one end of the second oil pipe is communicated with the first rod cavity, and the other end is communicated with the second rod cavity; the damping adjusting piece is arranged on the oil pipe, away from the frame of the vehicle, of the first oil pipe and the second oil pipe. According to the oil-gas balanced suspension system and the vehicle, the smoothness and the trafficability of the vehicle can be guaranteed at the same time.

Description

technical field [0001] The invention relates to the technical field of vehicle balance suspension, in particular to an oil-air balance suspension system and a vehicle. Background technique [0002] Suspension is an important part of the vehicle. It not only has the function of connecting the axle frame and buffering the impact of the ground, but also plays an important role in the ride comfort and passability of the vehicle. With the development of mining machinery, large-tonnage wide-body mining dump trucks have gradually applied oil-gas balance suspensions. [0003] At present, the oil-air balance suspension on the market mainly improves the bearing capacity of the suspension, but its ground adaptability is poor. Specifically: the oil-air balance suspension of traditional mine dump trucks usually makes the response of the oil-air spring The speed is fast, but because the response of the oil-gas spring is too fast, the vehicle will vibrate more, and the ride comfort of the...

[0003] At present, the oil-air balance suspension on the market mainly improves the bearing capacity of the suspension, but its ground adaptability is poor. Specifically: the oil-air balance suspension of traditional mine dump trucks usually makes the response of the oil-air spring The speed is fast, but because the response of the oil-gas spring is too fast, the vehicle will vibrate more, and the ride comfort of the vehicle will be poor. If the response speed of the oil-gas spring is reduced, the ride comfort of the vehicle can be improved, but when the vehicle passes through the pit When the road surface is sunken, it often occurs that the single bridge loses its driving momentarily and damages the axle, that is, the trafficability of the vehicle will be poor.
