Self compensation floating swing arm independent suspension system

Abstract

The invention provides a self compensation floating swing arm independent suspension system, comprising a self compensation floating swing arm independent suspension device and a centrifugal force control scissors-type anti-roll bar device. The two mechanisms can be used in combination or independently and are applicable to both front wheels and rear wheels. The self compensation floating swing arm independent suspension system guarantees that wheels perform line bounce along a vertical direction of a car body on various kinds of road surfaces when a car runs at a low speed or at a high speed or makes turns and guarantees maximum contact area between the wheels and the road surfaces, with the parameters of king pin angle, toe-in angle, camber angle, wheel track, and axle base being maintained the same as original parameters; and, when the car makes turns, the centrifugal force control scissors-type anti-roll bar device works automatically, offsets a roll force with a force equal to the roll force in magnitude and opposite to the roll force in direction, and enables the car body to lower automatically, thereby improving anti-roll capacity and realizing idealization of controllability, safety, stability and comfort of the car. The self compensation floating swing arm independent suspension system has a simple structure, excellent performance, and low cost, and is easy to realize.

Description

Technical field [0001] The invention relates to vehicle chassis technology, in particular to a self-compensating floating swing arm independent suspension system. Background technique [0002] By referring to "Automobile Technology", "Automobile Structure", "Detailed Explanation of the Advantages and Disadvantages of Various Suspension Forms" (excerpted from Liuzhou Automobile Network 2008-8-16) and other materials, and comparing with the existing technologies at home and abroad, the existing vehicle suspension system is generally Divided into two categories: non-independent suspension and independent suspension. It is also equipped with an anti-roll bar device to reduce the roll of the vehicle when turning. [0003] The structural feature of the non-independent suspension system is that the wheels on both sides are connected by an integral frame, and the wheels together with the axle are suspended under the frame or the body through an elastic suspension system. The non-i...

Problems solved by technology

[0006] The structure of the candle suspension has a big disadvantage: that is, the lateral force when the car is running will all be borne by the kingpin sleeved on the kingpin sleeve, resulting in increased friction resistance between the kingpins of the sleeve and serious wear

The main advantage of the multi-link suspension system is that the wheelbase and toe-in change are very small when the wheels jump, and the car can be turned smoothly according to the driver's intention regardless of whether the car is driving or braking. Shaft oscillation at high speed

It has two shortcomings, one is that the anti-roll effect is not obvious, and the other is that it partially offsets the advantages of independent suspension. Even when the vehicle does not turn, when one wheel jumps, the torsion bar will also drive the other side wheel to jump together.

The anti-roll bar connects the wheels on both sides, sacrificing the performance of the independent suspension in exchange for a limited anti-roll effect. If you don't get rid of this method, you won't have an ideal suspension device, and it will be difficult to make the vehicle's handling and stability Ideal for performance, comfort and safety
