Abstract

The invention relates to a horizontally-arranged hydraulic cylinder dynamic adjusting suspension. The suspension at least comprises two energy conversion units and a hydraulic adjusting unit, whereinan energy adjusting unit is arranged between the two energy conversion units through a pipeline; each energy conversion unit at least comprises a hydraulic cylinder and a torque transmission mechanismwhich are connected with each other; one of the energy conversion units is respectively connected with front wheels of the vehicle through two connecting rods; the other energy conversion unit is respectively connected with rear wheels of the vehicle through two connecting rods; under the condition that the wheels are stressed, a torque transmission mechanisms associate the torsion state of the connecting rods with the hydraulic state of the hydraulic cylinders so as to change the piston movement state of the hydraulic cylinders on the basis of the torque of the connecting rods. Therefore, under the condition that the hydraulic pressure difference occurs between the hydraulic cylinders with the connection relation, the hydraulic pressure adjusting unit adjusts the hydraulic pressure states of the hydraulic cylinders in a hydraulic pressure absorbing and/or releasing mode, the torsion state of the connecting rods is correspondingly adjusted based on the hydraulic pressure states of thehydraulic cylinders, and therefore the vertical load of wheels on a vehicle body is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a horizontally arranged hydraulic cylinder dynamic adjustment suspension. Background technique [0002] Vehicles with rigid axles typically have sway bars that limit lateral movement of the wheels relative to the vehicle's body. The sway bar or track bar typically comprises a rigid bar extending laterally in the same plane as the axle to connect one end of the axle to the body of the vehicle on the opposite side. The bar is attached on either end with a pivot that only allows the bar to rotate up and down so that the axle can only move vertically. Therefore, the stabilizer bar is generally mounted to the frame of the vehicle body through a bracket. The bracket must withstand lateral forces. A suspension system, such as an air suspension, can be mounted in the same area of ​​the body to accommodate the vertical movement of the axle and wheels relative to the body. [0003]...
