Problems solved by technology

[0002] The active roll control system improves the steering stability, smoothness, passing speed and safety of the vehicle when turning by controlling the vehicle's inclination to the inside of the turn; When the road surface is tilted, it automatically tilts at a certain angle to resist the centrifugal force and maintain a stable driving posture. The body roll is usually implemented in two ways: the independent roll of the body, and the linkage roll of the body and wheels. The steering movement of the vehicle is carried out independently without interfering with each other, and any steering mechanism can be used, but the handling stability and ride comfort of the vehicle are slightly

Embodiment Construction

[0037] Embodiments of the present invention will be described below according to the accompanying drawings.

[0038] The vehicle steering roll linkage mechanism consists of a roll mechanism and a steering mechanism (such as image 3 shown);

[0039] figure 1 The schematic diagram of the roll mechanism is shown. The roll mechanism includes: the right suspension ABCDE is composed of the right lower link 2, the right steering knuckle main shaft 4, the right upper link 6 and the ends of the right shock absorber 8. Parallel to and perpendicular to the plane where the right suspension ABCDE is located, the right steering knuckle 10 is connected with the right steering knuckle main shaft 4 around its axis BC, and the right steering knuckle 10 is connected to the right wheel 12 and controls its direction; the left suspension FGHIJ is composed of the left pull rod 3, The left steering knuckle main shaft 5, the left upper link 7 and the left shock absorber 9 are sequentially connected...

Abstract

The invention relates to the technical field of vehicle chassis, and discloses a steering and roll linkage mechanism of a vehicle and a roll control method. The steering and roll linkage mechanism ofthe vehicle is composed of a roll mechanism and a steering mechanism. A certain angle is formed between the left and right steering arms and the left and right knuckles, which are fixedly connected with each other, the two mechanisms share the body and the main shafts of the left and right knuckles, and two dynamic parallelograms are linked with double degrees of freedom to achieve the independentcontrol of body roll and vehicle steering. In the driving course of the vehicle, steering and roll, independent roll or independent steering can be achieved, and the wheelbase of vehicle does not change. The vehicle body rolls when the method is applied to the steering of the vehicle, so that the vehicle automatically rolls at a certain angle to resist centrifugal force or overturning force whensteering or driving on an inclined road, so as to maintain a stable driving attitude.

Description

technical field [0001] The invention relates to a vehicle steering roll linkage mechanism and a roll control method, belonging to the technical field of vehicle chassis, in particular to the technical category of vehicle steering under the condition of vehicle body roll. Background technique [0002] The active roll control system improves the steering stability, smoothness, passing speed and safety of the vehicle when turning by controlling the vehicle's inclination to the inside of the turn; When the road surface is tilted, it automatically tilts at a certain angle to resist the centrifugal force and maintain a stable driving posture. The body roll is usually implemented in two ways: the independent roll of the body, and the linkage roll of the body and wheels. The steering movement of the vehicle is carried out independently without interfering with each other, and any steering mechanism can be used, but the handling stability and ride comfort of the vehicle are slightly ...
