Vehicle Steering and Rolling Linkage Device and Vehicle Using the Device

Abstract

The invention relates to the technical field of vehicle chassis, and discloses a vehicle steering and rolling linkage device and a vehicle using the device. The vehicle steering and rolling linkage device is composed of a rolling mechanism and a steering mechanism. Steering knuckle spindle, upper tie rod, shock absorber, drive rod, steering knuckle and wheels, the steering mechanism is composed of connecting rods, left and right steering arms and the body to form a steering trapezoid, the roll mechanism and the steering mechanism share the same body, and the left and right The balance bar is linked through the ball hinge, through the dual-degree-of-freedom movement of vehicle steering and body roll, the independent control of vehicle steering and body roll is realized, and three working conditions of steering roll, independent roll or independent steering can be realized during the driving process of the vehicle ;Applied to the active roll of the vehicle body when the vehicle is turning, so that the vehicle automatically tilts at a certain angle when cornering or driving on an inclined road to resist centrifugal force or rollover force, so as to maintain a stable driving posture.

Description

technical field [0001] The invention relates to a vehicle steering roll linkage device and a vehicle using the device, 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 slightl...

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 worse when turning; the latter is the linkage roll method of the body and wheels, and the body roll and the vehicle steering movement affect each other , the handling stability, smoothness and safety of the vehicle are better when turning, but it needs to adopt two-wheel independent steering or four-wheel independent steering technology, adopt hydraulic drive, servo control steering wheels or servo motor drive, control steering wheels to meet the requirements of Ak However, the isosceles trapezoidal steering mechanism with simple structure and reliable operation does not meet the steering technical requirements under vehicle steering and roll conditions, and cannot be directly applied.
