Embodiment Construction

[0011] As shown in Figure 1, the guide (3) is located on the top of the shock absorber cylinder, and there are several channels going up and down inside, and the pressure limiting valve (9) is located at the upper opening of the channel, and its structure can be a plate valve or a ball valve. , cone valve, etc. The solenoid valve (10) spool is located on the pressure limiting valve (9), and the solenoid valve (10) coil is connected to the output port of the microprocessor (ECU). When receiving the action command from the microprocessor (ECU), the solenoid valve (10) coil will generate magnetic force to push the valve core to the pressure limiting valve (9) and close it, so that the oil will flow from the upper oil chamber (16) to the reservoir. The flow in the oil chamber (18) is blocked, thereby increasing the damping.

[0012] Such as figure 2 As shown, the microprocessor (ECU) is receiving the driver setting signal and a series of driving condition signals, such as: drive...

Abstract

The invention relates to electric control damp technology of the damper. It can be applied to suspending frame of car whose damper needs to change along with the driving condition. The invention has a quick electromagnetic valve and pressure limiting valve controlled by the electromagnetic valve, and the piston flow valve and the bottom valve of the traditional damper are changed into a single one-way valve which only permits the oil flow upwards. The design can make the oil flow upwards, thus, the adjustment to the compressing damp and the extending damp can be realized through the single control to the pressure limit valve switch. In order to consider the demands to the damp intensity of the damper of all driving conditions (load, road state, speed, lengthwise acceleration speed and transverse acceleration speed, and so on) and the aim of driver, the invention provides a microprocessor to receive the driver's aim signal and driving conditions, and carries on synthesis logic analysis to the signal and sends out electromagnetic valve output instructions, in order to realize the control to the resistance to the damper.

Description

technical field [0001] The invention relates to the electric control damping technology of the shock absorber. It is suitable for the suspension of various vehicles that require the damping of the shock absorber to change with the driving conditions. Background technique [0002] The vehicle's requirements for the damping strength of the shock absorber will change with the load, road conditions, vehicle speed, longitudinal acceleration, lateral acceleration, vertical acceleration and other driving conditions, and will also vary due to differences in driver personality. When the driving conditions change or there is a need to adjust the damping of the shock absorber, the shock absorber that cannot adjust the damping strength accordingly is difficult to achieve a satisfactory shock absorption effect, which will seriously affect the comfort of the vehicle. Compared with the existing fast adjustable (semi-active suspension) shock absorber, the electronically controlled variable...
