Embodiment Construction

[0028] Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings. Throughout the specification, the same reference numbers represent the same parts, and the same parts in the left-right symmetrical mechanism will omit repeated reference numbers and descriptions. The accompanying drawings are only for better describing the concept of the present invention, and the understanding of the concept of the present invention is not limited to the accompanying drawings.

[0029] 1. The height adjustment of the suspension.

[0030] Such as figure 1 , figure 2 As shown, figure 2 It is an embodiment of unequal-length double wishbone front suspension. The lower cross arm 2, the upper cross arm 3 and the bogie 8 constitute a double wishbone suspension mechanism. The upper end of the main spring 5 and the shock absorber 4 are connected in series with the screw rod 9, and the lower end of the shock absorber 4 adopts a pin shaft and The lower cr...

Abstract

A mechanical active suspension system of a vehicle is disclosed. It solves the problems of high price and high maintenance cost of active suspension, and further improves the performance of some aspects of active suspension. The mechanical active suspension system is characterized in that the fixed end of the spring in the suspension is connected with the vehicle body through a screw nut mechanismor a worm gear worm mechanism. The ECU controls the servo motor to drive the nut or worm to rotate so that the screw and the worm wheel drive the swing arm connected with the screw and the worm to generate the lifting and lowering motion with respect to the vehicle body so as to realize the height adjustment of the vehicle chassis. The ECU controls the servo motor to rotate the nut or the worm todrive the screw and the worm wheel to generate the lifting and lowering motion with respect to the vehicle body. Multi-stage spring is used in the suspension to realize the soft and hard adjustment of the suspension. The ECU controls the operation of each motor in real time according to the data fed back by each sensor. By adjusting the lifting and lowering of each independent suspension, it cancounteract the action of turning and tilting, braking nodding and starting and raising the head of the vehicle body. In the unequal-length double wishbone suspension, one wishbone is connected to thebody by an eccentric shaft, and the ECU controls the servo motor to drive the worm gear to drive the eccentric shaft to rotate to adjust the inclination angle between the wheel and the ground.

Description

Technical field [0001] The invention relates to a vehicle suspension system, in particular to a mechanical active suspension system. Background technique [0002] The ideal vehicle suspension system should: When the vehicle is driving on bumpy roads or off-road roads, the chassis should be taller and the suspension should be softer to improve the passing and comfort of the vehicle; when the vehicle is on a paved road , When driving at high speed on high-speed roads, the chassis should be lower and the suspension should be harder to improve the stability and handling of the vehicle. Under the traditional chassis technology, handling and comfort are a natural contradiction. Generally, they can only be tuned to one side. Designers try their best to find a balance between the two. Therefore, an active suspension with high energy and low energy, soft and hard performance will naturally be more popular. Currently, there are three widely used active suspension systems: air suspension,...
