Problems solved by technology

As a result of this feature, the traditional stabilizer bar can resist the body roll during the steering process, but it makes the car encounter a high bump, a large deep pit, or a large difference in road surface height between the wheels on one side of the car. Will produce greater body shaking and reduce the unilateral suspension travel

Embodiment

[0015] When the suspension stroke sensor 1 on the left and right side wheels 14 detects that the left and right suspension stroke difference is less than a certain threshold or when the steering wheel angle amplitude measured by the steering wheel angle sensor 5 is greater than a certain threshold, the control system 8 controls the left and right wheels. The valve 4 is in the closed state, so the stabilizer bar hydraulic support system 6 on the left and right sides of the stabilizer bar body 2 will be in a locked state. At this time, the stabilizer bar is equivalent to being connected with the vehicle body through a fixed support method, and will play a role in steering like a traditional stabilizer bar. Process resistance to body roll action.

Abstract

The invention relates to a hydraulic supporting system-based breakable automobile stabilizer bar system, which comprises a stabilizer bar, a control system and a stabilizer bar hydraulic supporting system, wherein the stabilizer bar consists of a stabilizer bar body and a stabilizer bar pull rod; the stabilizer bar hydraulic supporting system is based on controllable lock-up and switch-on and is connected to the left and right sides of the stabilizer bar body; the stabilizer bar body is connected with a suspension swing arm through the stabilizer bar pull rod; the suspension swing arm is positioned on wheels of a vehicle body fixed frame; a suspension travel sensor is positioned on a shock absorber; and the shock absorber, the wheels and a steering wheel angle sensor are fixedly arranged on thevehicle body fixed frame. The hydraulic supporting system-based breakable automobile stabilizer bar system has the beneficial effects that the stabilizer bar provides different roll stiffness according to different lateral accelerations during vehicle steering through the stabilizer bar hydraulic supporting system, so that the roll stiffness ratio of front and rear axles is changed according to the lateralacceleration of the vehicle, and the quickness and the stability of steering response are simultaneously considered by the vehicle.

Description

technical field [0001] The invention relates to a novel automobile stabilizer bar system, in particular to a detachable automobile stabilizer bar system based on a hydraulic support system. Background technique [0002] The car stabilizer bar is a stability system used to resist body roll, which is used to reduce the body roll caused by inertia during steering and improve the safety of drivers and passengers. [0003] The characteristic of the traditional stabilizer bar is that when there is a difference in the suspension stroke of the left and right suspensions, the pull rods at both ends of the left and right stabilizer bars are driven to move in opposite vertical directions through the guide rod or steering knuckle, and further the two ends of the stabilizer bar are moved in opposite directions. The reverse movement of the stabilizer bar, because the middle part of the stabilizer bar is fixed on the vehicle body through two supports, in this case the stabilizer bar will p...
