What is the function of the universal transmission device?
2 Answers
The universal transmission device serves to connect the transmission output shaft and the main reducer input shaft that are not aligned in a straight line, ensuring reliable power transmission even when the angle and distance between the two shafts frequently change. Universal transmission devices can be divided into two types: 1. Closed universal transmission device: It uses a single universal joint, with the drive shaft enclosed in a sleeve. The sleeve is connected to the frame via a ball joint, thus fixedly connected to the drive axle. 2. Open universal transmission device: It has a simple structure and is lightweight. Modern vehicles widely use open universal transmission devices.
I've been driving for over a decade and have long noticed the crucial role of universal joints in our daily driving. Simply put, their main function is to smoothly transmit the engine's power to the wheels, especially when turning or on bumpy roads. Think about it - cars don't always drive straight, and roads aren't perfectly flat. This device allows for angular changes between the driveshaft and wheels, preventing power interruption. For example, when you make a sharp turn at an intersection, without it, the entire chassis would shake violently, and you might even struggle to turn the steering wheel. Last time I drove my friend's old car, because this component was worn out, it made clicking noises when turning, and the repair cost quite a bit. Regular maintenance is crucial - checking for signs of looseness or wear - otherwise, it could cause major issues during long-distance driving. Overall, it ensures driving comfort and vehicle stability, making driving safer and smoother.
