Embodiment Construction

[0023] In this embodiment, the mechanical shock absorber of the original car has been improved, and a hydraulic cylinder has been added, through which the swing and shaking of the vehicle body in various directions can be controlled; electronic control devices, sensors and actuators have been added to the car , wherein: a plurality of sensors are installed on the vehicle body, and the state signals of the vehicle movement are transmitted to the control device through the sensors. The electronic control device mainly includes a microprocessor: the electronic control device receives the signal sent by the sensor, amplifies it through pulse width modulation, and then sends it to the digital solenoid valve. The flow of hydraulic oil is controlled by controlling the opening time of the solenoid valve, and then the movement of the hydraulic cylinder is controlled. The actuator includes hydraulic oil tank and power transmission device.

[0024] In this embodiment, the electronic con...

Abstract

The present invention relates to automobile and is one kind of electrically controlled automobile suspension. The present invention has the technological scheme comprising mounting hydraulic cylinder onto the mechanical damper and utilizing the damper as the piston rod of the hydraulic cylinder; adopting pulse width modulated digital solenoid valve as electronic controller and mounting sensors on to automobile body; and adopting electromagnetic clutch for the control of the middle pressure pump. The said technological measures result in hydraulic cylinder stroke change adaptive to complicated road case, greatly increased automobile body height regulating capacity, constant running level maintained, unchanged geometrical relation of automobile suspension, improved running performance, and other advantages.

Description

(1) Technical field: [0001] The invention relates to the field of automobiles, and relates to an electric control suspension for automobiles. (two) background technology: [0002] At present, the shock absorbers used in the shock absorption system of traditional cars are mainly composed of elastic elements, shock absorbers, and guide mechanisms. Due to the comprehensive characteristics of elastic elements and shock absorbers, the driving performance and operating performance of the car are affected, making the passenger Seat comfort and operational stability cannot be satisfied at the same time in the traditional constant stiffness spring and constant damping shock absorber suspension. It can only ensure that the car can achieve the best performance compromise under a certain road and speed conditions, and can only be passive. It can effectively bear the force of the ground on the body, but cannot actively control these forces. Therefore, in order to overcome the limitation...
