Abstract

The invention provides a hydraulic suspension system and a vehicle, the hydraulic suspension system comprises a suspension unit, the suspension unit comprises a hydraulic pipeline and at least two hydraulic actuators, each hydraulic actuator comprises a cylinder barrel, a piston part, a piston rod and an energy accumulator, the cylinder barrel connected with an vehicle body is provided with a sliding cavity, the piston part is arranged in the sliding cavity in a sliding mode; the sliding cavity is divided into an upper cavity and a lower cavity by the piston part; one end of the piston rod is connected with the piston part, while the other end of the piston rod is connected with the axle; an energy storage cavity and a partition part are arranged in the energy accumulator, the partition part divides the energy storage cavity into a liquid cavity and a gas cavity used for storing gas, and the liquid cavity is communicated with the upper cavity; the upper cavities are communicated through the hydraulic pipeline. According to the hydraulic suspension system and the vehicle, the multiple hydraulic actuators are arranged, the upper cavities of the hydraulic actuators are communicated through the hydraulic pipelines, the bearing capacity and shock resistance of the vehicle are improved. Meanwhile, the smoothness and operation stability of the vehicle can be considered, the impact load of a single wheel is reduced, and the tire grounding performance is improved.

Description

technical field [0001] The invention relates to the technical field of automobile suspension structures, in particular to a hydraulic suspension system and an automobile. Background technique [0002] At present, airbags, coil springs, leaf springs, etc. are mostly used as the elastic elements of vehicle suspension. In addition to the elastic elements, the vehicle suspension also needs to be matched with shock absorbers to provide damping. For lateral stability, it is generally equipped with a stabilizer bar. [0003] However, due to the large load-to-empty ratio of such vehicles, the load-carrying capacity and comfort of the leaf spring suspension cannot be taken into account at the same time, especially for multi-axle and Vehicles with shorter wheelbases have higher requirements for installation space. For heavy-duty special vehicles with leaf spring suspension, the working environment is very harsh, and the vehicle's empty-to-full-load ratio is large. Suspension service...
