The functions of a transmission can be categorized into the following three types: 1. Speed and torque variation: To expand the range of torque and speed transmitted from the engine to the driving wheels, adapting to frequently changing driving conditions. 2. Direction change: To enable the vehicle to reverse while maintaining the engine's rotation direction. 3. Power interruption: Utilizing neutral gear to interrupt power transmission, allowing the engine to start, idle, and the vehicle to stop briefly or coast. In off-road vehicles, to distribute the power output from the transmission to each drive axle, a transfer case is installed behind the transmission. The transfer case is also a gear transmission system, with its input shaft connected to the transmission's output shaft via a universal drive, and the output shafts connected to each drive axle through universal drives.

Why is the windshield washer fluid consumed so quickly?

If the windshield washer fluid in your car is being consumed rapidly, it may be due to a leak in the washer fluid reservoir. Function of windshield washer fluid: Windshield washer fluid helps slow down the aging of wiper blades. When using the wipers, the blades can produce a harsh scraping noise due to their stiffness. The ethylene glycol in the washer fluid has high viscosity, which provides lubrication and reduces friction between the wiper blades and the windshield. Additionally, the presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, offering antifreeze properties and quickly dissolving frost. Location of the washer fluid reservoir: There is a filler-like reservoir near the front bumper in front of the engine. This reservoir is the windshield washer fluid filler. While driving, dust or other debris can obstruct visibility through the windshield, making the washer fluid particularly important.
