Abstract

The application relates to the field of vehicle parts, and provides an active stabilizer bar, an assembly method and a vehicle. Compared with the power between the damper and the output rocker of the output rocker flange and the damper output flange which are assembled in a split mode in the prior art, the active stabilizer bar provided by the application utilizes the sleeve formed into an integrated structure to transfer the power between the damper and the output rocker, so that a lock nut, a lock bolt gasket and an O-shaped ring which are originally needed to be arranged for assembling the output rocker flange and the damper output flange can be omitted.

Description

Active stabilizer bar, assembly method and vehicle Technical Field The application relates to the technical field of vehicle parts, in particular to an active stabilizer bar, an assembly method and a vehicle. Background At present, active stabilizer bar products are widely applied to part of vehicle types. The active stabilizer bar has a main function of generating a moment against the roll of the vehicle body when the roll of the vehicle body occurs during traveling, thereby maintaining the stability of the vehicle body. Typically, the motor of the active stabilizer bar is activated upon receipt of a signal and outputs torque that is transferred to the output rocker arm through the multi-speed reducer assembly. However, the installation of the mechanical part between the output rocker arm and the speed reducer assembly through a simple and efficient structure is a current difficulty to be solved, because the complex installation structure will lead to the complexity of the active stabilizer bar production process and the increase in assembly time. In addition, a set of rubber cushioning mechanism is needed between the output rocker arm and the speed reducer assembly to absorb the load of the output rocker arm during rotation, meanwhile, the service life problem of the rubber cushioning mechanism between the output rocker arm and the speed reducer assembly is solved, and if the rubber cushioning mechanism is damaged in advance in the service life period of the active stabilizer bar, the service life of the active stabilizer bar is finished in advance. Disclosure of Invention In view of the above, the present application provides an active stabilizer bar, an assembling method and a vehicle, and aims to provide an active stabilizer bar with less assembling steps and time, firmness and reliability, and to solve the above technical problems to a certain extent. The active stabilizer bar provided according to the first aspect of the present application includes a damper, a sleeve and an output rocker arm, The damper is in transmission connection with the sleeve, and the output rocker arm is connected with the sleeve, so that the damper drives the output rocker arm to rotate; Wherein the sleeve is formed as a unitary structure.
