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 th

Embodiment 1

[0062] Basic type, such as Figure 9, single group, horizontally placed, composed of floating swing arm (405), compensation mechanism (400), steering knuckle (410), and positioning shock absorber (411), the structure is the simplest, and the basic performance fully meets the requirements. performance, the swing arm can be widened or directly designed as an A shape to increase strength.

Embodiment 2

[0064] commonly used, such as Figure 10 The two sets of devices are distributed at 90 degrees, and the force is reasonable and the structure is relatively simple. The vertical swing arm (405) and compensator (400) only bear the tension when braking or when the wheel encounters resistance, so it can be smaller. to reduce mass

Embodiment 3

[0066] flexible arrangement, such as Figure 11 , installed in any direction perpendicular to the plane of the car body, similar to the basic type.

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...
