Rotary Damper Working principle: one of the advantages of disc braking is that friction pads and brake discs produced by friction will soon be thrown out, the heat will also be the brake disc faster distribution out, so as to obtain better braking performance. The drum brakes are obviously relatively weak in this respect. Because of the rapid response of disc brakes and the ability to do high frequency braking, many cars use disc brakes and ABS systems, as well as VSC and TCS systems to meet the need for rapid operation of such systems. For these reasons, and in order to obtain a large braking capacity, many cars are fitted with four-wheel brakes. Some models in the brake caliper will install a damper, it can be effective in the braking process of the noise control, this noise mainly comes from the brake pads and brake disc friction between the vibration, and the addition of the damper can be part of this vibration to resolve. The rotary damper is to use the braking mechanism to make the brake shoe pressed on the inside of the brake friction plate, thus producing the braking force, slowing the wheel or stopping in a short distance according to the need, to ensure the safety of the driving, and to guarantee the car parking reliable can not slip automatically. Drum brakes of the rotating components is the brake drum, the fixed element is the brake hoof, the cost, and conforms to the traditional design.Vane Rotary Dampers.
The characteristics of the rotary damper: speed, rotating damper According to the change of the rotational speed, the torque also changed. The change law is as follows: The speed is increased and the torque is increased. The speed slows and the torque drops. The torque differs from the standard torque when starting.Vane Rotary Dampers.
The temperature characteristic, the rotary damper according to the use ambient temperature change, the torque also has the change. The change rule is as follows: when the ambient temperature increases, the torque decreases and the ambient temperature decreases. This is because the viscosity of the viscous oil in the damper changes as the ambient temperature changes. However, when the ambient temperature is restored to normal temperature, the torque is restored to its original value.Vane Rotary Dampers.
