Car body rolling limiting device and car adopting device

Abstract

The invention relates to the technical field of car chassis, and discloses a car body rolling limiting device and a car adopting the device. The car body rolling limiting device comprises a car frame,a car body, a limiting wheel, a swing rod and a roller. The car body and the limiting wheel rotate together relative to the car frame. The cam profile of the limiting wheel constrains the roller to form two limiting positions of the swing rod, at the right limiting position of the swing rod, the car body rolling work state is kept through electromagnetic pushing force, and at the left limiting position of the swing rod, the rolling lock state is reset by spring tension. An actuator drives the car body to do rolling motion relative to the car frame, any car body rolling angle beta is obtained,and the functions of car body active rolling, left and right limiting car body roll angle limiting and automatic reset of car body roll angle zero returning after failure power off are achieved. Thedevice is applied to car body active rolling when the car turns, so that the car body actively rolls by a certain angle to resist centrifugal force or roll-over force when the car turns or passes through an inclined pavement, and the stable running posture of the car is kept.

Description

technical field [0001] The invention relates to a vehicle body roll limiting device and a vehicle using the device, belonging to the technical field of vehicle chassis, in particular to the technical field of vehicle body roll 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 a stable driving posture of the 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 the steering stability of the vehic...

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 handling stability of the vehicle when turning , ride comfort and safety are better, and it needs 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; independent body roll mode, body roll and vehicle steering movement are carried out independently without interfering with each other, any steering mechanism can be used, the structure is simple, and the cost is low. Usually, the actuator directly drives the body to rotate relative to the frame, resulting in The handling stability, ride comfort and safety reliability of the vehicle when turning are poor; explore the drive mode of independent body roll, study the limit and control method of independent body roll, in order to reduce the cost of active roll vehicles and improve the quality of vehicles with independent body roll Performance has theoretical significance and practical value
