Self-adaptive hydraulic sidesway balance system

Abstract

In order to overcome shortcomings of performances of an existing suspended anti-sidesway system, the invention breaks the routine thoroughly, a conventional suspension mode of using an anti-sidesway torsion bar to connect wheels on the two sides or lower arms is abandoned, and by changing a force bearing point and a force direction, a harmful sidesway force is converted into a useful reacting force for offsetting the sidesway force in a most scientific mode. The sidesway force is balanced with the reacting force which has the same strength as the sidesway force and is opposite in direction. Under the control by a parameter control unit, the sidesway force is balanced out during vehicle turning, a vehicle body is lowered, and safety and controllability are improved; during straight running of the vehicle, wheels jump freely, and comfort is enhanced. Extension and locking of hydraulic axial clutches of a front balance device and a rear balance device are controlled respectively in real time through the parameter control unit, and poor states that the vehicle nodes during braking and raises the head during starting and acceleration are changed to improve riding comfort.

Description

[0001] 1. Technical field: [0002] The invention relates to vehicle chassis technology, in particular to a vehicle self-adaptive hydraulic roll balancing system. [0003] 2. Background of the invention: [0004] By referring to "Automobile Technology", "Automobile Structure", "Detailed Explanation of the Advantages and Disadvantages of Various Suspension Forms" and other materials, and comparing and analyzing with the existing technologies at home and abroad, it is found that the existing vehicle suspension system is used to prevent rollover when the vehicle is turning. The lower arms of the left and right suspensions of the vehicle are connected to an anti-roll torsion bar, which uses the rebound force generated by the torsion of the bar body to restrain the body from rolling and prevent the car from rolling over. Figure 1 . These technologies can reduce the roll of a part of the vehicle body when the centrifugal force acts on the body when cornering. But at the same time, ...

AI Technical Summary

Problems solved by technology

It can be seen that without getting rid of this method, an ideal anti-roll suspension device will not be produced, and it will be difficult to idealize the handling, stability, comfort and safety of the vehicle.
