Inner ball cage&telescopic constant velocity universal joint
The inner ball cage is a component that connects the differential and intermediate shaft, and is a device with functions such as transmitting torque, changing working angle, and compensating for axial slip.The internal cage structures mainly include TJ structure, VL structure, AAR structure, DOJ structure, LJ structure, ETJ structure, EDJ structure, and PTJ structure, among which the most commonly used are TJ structure, VL structure, AAR structure, DOJ structure, and LJ structure; The outer wheels of TJ structure, AAR structure, and DOJ structure adopt precision forging forming technology to ensure stable raceway size and excellent surface accuracy, achieving high NVH performance.
