What is the working principle of the reverse gear in a transmission?
1 Answers
The working principle of the reverse gear in a transmission varies depending on the type: 1. For manual transmissions, the reverse gear works by shifting the gear lever to switch the driving gear on the intermediate shaft, engaging different gear combinations with the power output shaft to alter the torque and speed of the driving wheels. 2. For automatic transmissions, the reverse gear operates using a planetary gear mechanism to change speed automatically based on the degree of throttle pedal pressure and vehicle speed changes, requiring the driver to only control the speed via the accelerator pedal. The functions of a transmission include: 1. Changing the transmission ratio to expand the range of torque and speed variations for the driving wheels. 2. Enabling reverse driving without altering the rotation direction of the engine crankshaft. 3. Interrupting power transmission to the driving wheels during engine start, idle operation, gear shifting, or when stopping to output power. 4. Allowing neutral gear, where the transmission does not output power when the clutch is engaged.
