What is a Retarder?
1 Answers
Retarder is used as an auxiliary device for the braking system, mainly applied to buses over 5 tons and trucks over 12 tons. For vehicles frequently operating in mountainous or hilly areas, its primary function is to enable sustained speed reduction or maintain stable speed during long downhill descents, while alleviating or eliminating the load on service brakes. Detailed information about retarders is as follows: 1. Based on different working principles, they can be classified into engine retarders, hydraulic retarders, electric turbo retarders, motor retarders, and aerodynamic retarders. 2. According to different forms of braking torque application, they can be categorized as primary retarders (acting on the front end of the transmission) and secondary retarders (acting on the rear end of the transmission).
