Electronically controlled stiffness adjustable active lateral stabilizer

Abstract

The invention relates to an electrically-controlled rigidity-adjustable initiative laterally stabilizing device. The electrically-controlled rigidity-adjustable initiative laterally stabilizing device comprises a stabilizer bar which is composed of the first stabilizer half bar and the second stabilizer half bar. A dynamic executing mechanism is connected between the first stabilizer half bar and the second stabilizer half bar. The dynamic executing mechanism comprises a shell, a worm wheel and a worm, wherein the worm wheel and the worm are located in the shell. The worm is connected with a motor through an electromagnetic clutch. An inner ring gear is arranged in the worm wheel. The first stabilizer half bar penetrates through the shell and is fixedly connected with a flanging disk arranged on the end face of the worm wheel. The second stabilizer half bar is provided with a central gear which is meshed with the inner ring gear in the worm wheel through a transition gear to form a gear transmission mechanism. Through the control over the rotating speed and the current magnitude of the motor, the first stabilizer half bar and the second stabilizer half bar can twist relatively in varying degrees to generate different torques. Consequently, rigidity adjustment of a roll angle of an automobile can be achieved, the roll angle of the automobile can be decreased, and stability, riding comfort and safety of the driving automobile can be improved.

Description

technical field [0001] The invention relates to an active lateral stabilizing device for automobiles, in particular to an electronically controlled stiffness-adjustable active lateral stabilizing device. Background technique [0002] The purpose of the stabilizer bar is to generate a torsional moment from one side of the vehicle to the other when the car is turning or driving on a bumpy road, thereby preventing excessive roll of the car body and allowing the load on each wheel to be distributed in a balanced manner. However, when the vehicle speed, steering wheel angular velocity, steering wheel angle, load and other parameters are different when the car is turning, the fixed distribution ratio of the vertical load on the left and right wheels will affect the cornering characteristics of the tires, resulting in changes in the steady state response of the car , rollover occurs when the inner wheel leaves the ground. Therefore, the fixed rigidity of the traditional stabilizer...
