What are the types of universal transmission devices?
1 Answers
Universal transmission devices can be classified into enclosed universal transmission devices and open universal transmission devices. A universal transmission device is used to transmit power between two shafts whose relative positions constantly change during operation. Its function is to connect the transmission output shaft and the differential input shaft, which are not aligned, and ensure reliable power transmission even when the angle and distance between the two shafts frequently change. The enclosed universal transmission device uses a single universal joint, with the drive shaft enclosed in a sleeve. The sleeve is connected to the frame via a ball joint and fixed to the drive axle. Its most notable feature is that the transmission housing serves as a thrust tube to transmit the vehicle's longitudinal force, allowing the drive shaft housing to function as a longitudinal swing arm in the suspension system's guiding mechanism. The open universal transmission device has a simple structure and is lightweight, making it widely used in modern vehicles.
