Description

Active transverse stabilizer bar and vehicle with same Technical Field The utility model relates to the technical field of vehicle parts, in particular to an active transverse stabilizer bar and a vehicle with the same. Background With the increasing competition of new energy passenger cars in the market, the vehicle configuration is further improved, and the active transverse stabilizer bar applied to high-end car types in the past is also increasingly applied. As shown in fig. 1 and 2, in the prior art, a fixed end rocker arm 91 and a housing 92 of an actuator package are welded together by a welding process to form an input end, and an output end rocker arm 93 is screwed together with an end face spline connector 94, and the end face spline connector 94 is connected with an output shaft of a three-stage planetary gear reduction mechanism 95 by a shock absorbing structure. The output rocker arm 93 rotates along with the output torque of the actuator in the working process, so a thrust bearing 97 is arranged between the output rocker arm 93 and the shell 92, an outer ring of the thrust bearing 97 is in clearance fit with the shell 92, an inner ring of the thrust bearing is connected with the end face spline connector 94, and the end face spline connector 94 is matched with an output shaft of the three-stage planetary reduction mechanism 95, so that torque output is formed.
