Universal joint, is a very important car parts.
Universal joint, is a very important car parts.
Universal joints and drive shaft combination, known as the universal joint transmission. In the front-engine rear-wheel drive vehicles, the universal joint transmission device installed in the transmission output shaft and drive axle between the main reducer input shaft; while front-engine front-wheel drive vehicles omitted shaft, universal joint installation In the face of responsible driving is also responsible for steering the front axle between the axle and wheels.
Universal joints with (Universal Joint Mate)
In line with universal joints, a parts (output shaft) around its axis of rotation was done by another component (input shaft) around its axis of rotation-driven.
Universal Joint universal joint that is the English name of the universal joint, is to achieve variable power transmission of the mechanical point of view for the need to change the direction of shaft-line position, which is the vehicle drive system of the universal transmission device of "joint" part. Universal joints and drive shaft combination, known as the universal joint transmission.
The structure and role of the universal joints a bit like the human body on a limb joints, which allows the parts are connected between the change in angle within a certain range. To meet the power transmission, steering and vehicle to adapt to run-time generated by beating up and down the angle caused by changes in the former driving the car drive axle, axle and axle joints between the commonly connected. However, due to the axial size restrictions and require relatively large angle again, a single universal joints can not make the output shaft and the shaft into the shaft of the instantaneous angular velocity equal, likely to cause vibration, mechanical damage increased, resulting in considerable noise, Therefore, extensive use of a wide range of constant-velocity joints. Former drive vehicles, each axle with two constant velocity universal joint, close to the variable speed drive axle is the axle universal joints inside the joints, near the axle is the axle outside of joints. In the latter driving the car, engine, clutch and transmission installed in the frame as a whole, while driving through the elastic suspension bridge to connect with the frame, there is a gap between the need to connect. Uneven road vehicle operation, resulting beating, load change, or two to install the potentiometer assembly, will be making transmission output shaft and drive axle final drive input shaft angle and distance between the change, so in the post-drive vehicle of the universal joint transmission forms a dual universal joint, that is, drive shaft universal joints at both ends of each one, whose role is to make the same angle between the shaft ends to ensure that the output shaft into the shaft axis and the instantaneous angular velocity is always the same.
