What is the principle of a transmission?
1 Answers
Mechanical transmissions primarily utilize the speed reduction principle of gear transmission. Below is an introduction to transmissions: 1. Function: A transmission contains multiple sets of gear pairs with different transmission ratios. The gear-shifting action during vehicle operation involves using the control mechanism to engage different gear pairs. For example, during low-speed operation, gear pairs with larger transmission ratios are engaged, while during high-speed operation, gear pairs with smaller transmission ratios are used. 2. Composition: A transmission consists of two main parts: the gear transmission mechanism and the gear control mechanism. The primary function of the gear transmission mechanism is to alter the magnitude and direction of torque and rotational speed. The control mechanism's main role is to manage the transmission mechanism, enabling the switching of transmission ratios (i.e., gear shifting) to achieve speed and torque variation.
