Abstract

The invention discloses a vehicle active transverse stabilizer bar, and mainly relates to the field of active safety of vehicles. The vehicle active transverse stabilizer bar comprises a servo motor, a transverse stabilizer bar body and a planetary gear mechanism. The servo motor is a power source and provides power for the vehicle active transverse stabilizer bar, the power is transmitted to the planetary gear mechanism by the servo motor, the transverse stabilizer bar body is broken in the middle and is divided into a left part and a right part, a left side structure and a right side structure of the planetary gear mechanism are symmetric and are both two-stage speed reduction torque increase dual-planetary gear mechanism bodies, and the left part and the right part of the transverse stabilizer rod body are connected to the left output end and the right output end of the servo motor respectively through splines. The vehicle active transverse stabilizer bar overcomes the defect that the capacity of a passive transverse stabilizer rod for resisting large-margin side inclination of a vehicle body is insufficient, and the vehicle active transverse stabilizer bar has the advantages of being simple and practical in structure, strong in bearing capacity, high in system reliability and capable of reducing vehicle side inclination angles and improving vehicle handling stability.

Description

technical field [0001] The invention relates to an automobile lateral stabilizer bar, in particular to an automobile active lateral stabilizer bar. Background technique [0002] At present, most of the stabilizer bars used in domestic automobiles are passive stabilizer bars, while the domestic independent development capability of active stabilizer bars for vehicles still needs to be improved. Nowadays, many manufacturers' research on active stabilizer bars only stays at the level of control systems and control laws, and few people study the structure of stabilizer bars. [0003] When the car is impacted by the road surface and turns at high speed, the car will roll, which will bring discomfort to the driver. The main function of the stabilizer bar is to reduce the roll angle of the vehicle body and improve the driver's handling stability and comfort. Due to the limited ability of the passive stabilizer bar mainly used in current automobiles to resist body roll, especially...
