What is the principle of a retarder?

The principle of a retarder is to energize the excitation coil of the stator assembly through a control circuit, generating a magnetic field. The rotor assembly rotates at high speed along with the vehicle's transmission parts, cutting the magnetic lines of force and producing a reverse torque to decelerate the vehicle. Retarders are classified into first-level retarders and second-level retarders based on torque. A retarder consists of a rotor, stator, working chamber, input shaft, heat exchanger, oil storage tank, and housing. The method of using a retarder is as follows: when the vehicle is ignited, the retarder is in standby mode. When the vehicle needs to decelerate, pulling the manual control switch handle step by step to the desired gear can achieve the deceleration purpose. To turn off the retarder function, simply pull the manual control switch handle back to the 0 position.

Can You Still Drive After the Tire Pressure Warning Light Comes On?

You should not drive after the tire pressure warning light comes on. The purpose of the tire pressure warning is to automatically alert and display the tire status when there is air leakage, excessive or insufficient tire pressure, or excessively high temperature, ensuring driving safety. The normal range for car tire pressure is between 2.2 and 2.8 bar. The hazards of excessive tire pressure include: 1. Reduced tire friction and adhesion, affecting braking performance; 2. Causing steering wheel vibration and deviation, reducing driving comfort; 3. Accelerating uneven wear of the central tread pattern, leading to tire bulging and stone trapping; 4. Overstretching and deforming the tire cords, reducing tire elasticity, increasing the load on the car while driving, and decreasing puncture resistance.
