Embodiment Construction

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 It is a schematic diagram of the overall structure of the pickup truck suspension system of the present invention. It can be seen that the pickup truck suspension system of the present invention adopts the hydraulic control principle, and adjusts the working state of the hydraulic actuator parts to adapt to different road condition information according to the actual road conditions and vehicle body status.

[0024] Specifically, the pickup suspension system includes a sensor, an electronic control unit 21 (Electronic Control Unit) and a hydraulic device. Among them, the sensor is used to sense the actual working state of the car body, and detect the car body vibration, wheel beating, body height and tilt ...

Abstract

The invention provides a pickup suspension system which comprises an electronic control unit, a hydraulic device and a sensor used to detect a vehicle travelling state, wherein the hydraulic device comprises a hydraulic pump, a reversing valve and a hydraulic cylinder of which two ends are connected to a frame and an axle of a pickup respectively; the hydraulic pump is connected to a power input component; the electronic control unit is connected to the power input component and the reversing valve respectively; and the electronic control unit receives vehicle travelling state signals detected by the sensor, compares the signals with set state signals, generates an adjustment signal and then adjusts working states of the power input component and / or the reversing valve. The hydraulic device is disposed, and the electronic control unit adjusts the working state of the hydraulic device according to the actual vehicle travelling state detected by the sensor; and when the vehicle passes through a complicated pavement, the hydraulic device can rapidly adjust a stretching length of the hydraulic cylinder between the frame and the axle, so problems such as wheel separation from the ground and disappearance of attachment force caused by pavement changes can be reduced.

Description

technical field [0001] The invention relates to the technical field of automobile components, in particular to a pickup suspension system. Background technique [0002] A pickup truck is a model that uses a car front and cab, as well as an open cargo compartment. The rear axle of existing pickup trucks mostly adopts an integral structure, so the rear suspension system mostly adopts a non-independent suspension system. [0003] The available non-independent suspensions are coil spring non-independent suspension and leaf spring non-independent suspension. In such a suspension system, the steel plate and spring stiffness are invariable. In the actual driving process, the greater the sprung mass, the greater the vertical deformation of the suspension. The natural frequencies are quite different. The frequency used by the human body is 1-1.6Hz. In order to consider the loading situation, the natural frequency of the truck body under the no-load situation greatly exceeds the ab...
