Problems solved by technology

[0003] Vehicle active roll technology is usually implemented in two ways: independent body roll and body and wheel linkage roll, among which: body and wheel linkage roll, the interaction between body roll and vehicle steering motion, and the steering stability of the vehicle when turning , ride comfort and safety are better, and it is necessary to adopt two-wheel independent steering or four-wheel independent steering, or use a vehicle steering and rolling linkage device composed of a rolling mechanism and a steering mechanism, but the structure is complicated and the cost is high, so it is suitable for High-end vehicles; the body rolls independently, the body moves relative to the frame, the b...

Abstract

The invention relates to a vehicle body tilting mechanism and an active tilting vehicle applying the same. The invention belongs to the technical field of vehicle chassis, the invention relates to thetechnical field of vehicle body tilting driving and control, the vehicle body tilting mechanism is composed of a tilting mechanism and a steering mechanism, a vehicle body moves relative to a suspension, an actuating angle alpha and a steering angle theta serve as control parameters, vehicle body tilting and vehicle steering two-degree-of-freedom movement is achieved, and wheels do not tilt in the vehicle body tilting process and the vehicle body tilting mechanism is suitable for universal car tires. Three working conditions of steering side inclination, independent side inclination or independent steering can be realized in a vehicle driving process, and the steering side inclination device is applied to active side inclination of a vehicle body when the vehicle steers, so that the vehicle can automatically incline for a certain angle to resist centrifugal force or side overturning force when turning over or driving on an inclined road surface, and a stable driving posture is kept.

Description

technical field [0001] The invention relates to a vehicle body roll mechanism and an active roll vehicle using the mechanism, belonging to the technical field of vehicle chassis, in particular to the technical field of vehicle body roll drive and control. Background technique [0002] The active roll control system improves the handling stability, smoothness, traffic speed and safety of the vehicle when turning by controlling the degree of inclination of the vehicle to the inner side of the turn. When crossing an inclined road, it automatically tilts at a certain angle to generate a balance moment to resist the centrifugal force or rollover force on the vehicle, so as to maintain the stable driving posture of the small wheelbase vehicle. [0003] Vehicle active roll technology is usually implemented in two ways: independent body roll and body and wheel linkage roll, among which: body and wheel linkage roll, the interaction between body roll and vehicle steering motion, and t...
