High Accuracy Testing System of Transmission Performance and Reliability

Introduction

A transmission is a machine in a power transmission system, which provides controlled application of the power. Transmissions can be automatic or manual. In a manual transmission, the operator shifts the lever to a higher or lower gear to control the speed and torque of the engine and wheels. The operator presses the clutch and then shifts the gear for smooth transmission. In an automatic transmission, the transmission automatically shifts through different gears based on the use of the gas and brakes from the driver. Various tests should be performed on the gearbox to ensure its working performance, including a shift performance test, transmission test, leak test, and noise test. The transmission test bench is the test bench which is situated at the end of the assembly line to check the above parameters in driving and the dragging test. The synchromesh test is carried out to check the test bench is running properly or not.

Application

Any vehicle requires more torque while ascending on the hill and less speed. Vice versa vehicle requires less torque on level roads. High torque is not required because of the momentum of the vehicle. Hence some system is needed which can change the vehicle’s torque and its speed according to the level of road or when the operator requires it. This device is known as the transmission box or the gearbox. The main function of the gearbox is to transmit the torque and motion between the prime shaft and the drive shaft in the driving and the dragging conditions. The rotation of the front wheel and the rare wheel must be the same.
