Abstract

The invention discloses a vehicle, comprising: a vehicle frame, left front and right front leaf springs, left front and right front pilot type shock absorbers, left front and right front brake cylinders, the left and right front leaf springs are respectively arranged on the vehicle frame The left and right front sides of the left and right front side; the lower ends of the left and right front pilot shock absorbers are respectively connected with the left and right front leaf springs and the upper ends are connected with the frame, and each of the left and right front pilot shock absorbers is It includes a housing and a regulating valve. The housing has a bottom cavity and an oil storage cylinder. The regulating valve includes a valve body and a valve core. The valve body has a valve cavity. In the valve cavity, the fluid medium enters the valve cavity from the control port, and the spool isolates the bottom cavity and the oil storage cylinder; the left front and right front brake cylinders are respectively connected to the control ports of the left and right front pilot shock absorbers. According to the vehicle of the present invention, the running comfort of the automobile can be improved, and the braking nodding phenomenon thereof can also be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a vehicle. Background technique [0002] During the braking process of the car, due to the action of inertial force, the load will be transferred, that is, the axle load of the front wheel increases, and the axle load of the rear wheel decreases, which is manifested as a braking nod phenomenon. Brake nodding has a great influence on the handling stability, passability and comfort of the car. Therefore, its anti-nodding effect must be considered in the design of automobile suspension system. During the turning process of the car, the roll force caused by the lateral acceleration causes the outer suspension system of the car to be compressed and deformed, causing the whole vehicle to tilt outward, and the position of the center of mass to shift outward, which reduces the handling stability of the car and rolls over. The threshold value drops, and the ability to resi...
