Vehicle steering-rolling linkage device and active rolling vehicle

Abstract

The invention relates to the technical field of vehicle chassis, and discloses a vehicle steering-rolling linkage device and an active rolling vehicle. The vehicle steering-rolling linkage device is formed through linkage of rolling mechanisms and a steering mechanism, each rolling mechanism comprises a vehicle body, a lower pull rod, a steering knuckle main spindle, an upper pull rod, a shock absorber, a rocker, a steering knuckle, wheels, a supporting rod and a driving rod, and the steering mechanism is in a steering trapezoid shape formed by a connecting rod, left and right steering arms and the vehicle body. The rolling mechanisms and the steering mechanism share the same vehicle body, and linkage is achieved through left and right balance levers via a spherical hinge; through vehiclesteering and vehicle body rolling two-degree-of-freedom movement, it is achieved that vehicle steering and vehicle body rolling are separately controlled. In the vehicle driving process, three workingconditions of steering rolling, separate rolling and separate steering can be achieved; the linkage device is used for active vehicle body rolling during vehicle steering, so that when the vehicle turns off or passes through a slope road, the vehicle automatically tilts a certain angle to resist centrifugal force or rollover force, and a stable driving attitude is kept.

Description

technical field [0001] The invention relates to a vehicle steering roll linkage device and an active roll vehicle, 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 wo...

[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.
