Description
Technical Field

Background
The hydraulic retarder is a retarder for reducing the running speed of a vehicle through a hydraulic device, and has unique advantages particularly in the downhill braking process of the vehicle. The main working principle is that the rotor rotates to drive the liquid to rotate, so that a certain impact force is generated on the stator, the Newton's law of interaction force shows that the rotor blade is bound to receive a reaction force, and the braking torque generated by the reaction force provides a certain braking effect.
Different road conditions need to provide different braking effects, so that the research on the automatic regulation function of the braking effect of the hydraulic retarder is of great significance. Factors that actually affect the braking effect of the hydrodynamic retarder are many, such as the amount of liquid filling, the number of blades, the diameter of a circle, the inclination angle of the blades (the forward inclination of the blades increases the braking effect), the rotor speed, and the like.
In order to achieve the purpose of providing different braking effects for automobiles under different driving road conditions, experts and technicians in the related art have made many attempts. The common method in the market at present is to control the liquid filling amount of the hydraulic retarder (the ratio of the oil content to the air content inside the hydraulic retarder) by using a sensor, and further achieve the purpose of adjusting the braking effect of the hydraulic retarder according to road conditions. However, as the amount of the charged liquid increases, the energy waste caused in the oil liquid backflow process will also become larger, and another automatic adjustment method is urgently needed to be found to reduce the energy loss.
In nature, the scales on the wings of the butterfly have the function of automatically regulating the body temperature. The mechanism is mainly that the radiation angle of sunlight is changed by adjusting the inclination angle of the scale, so that the amount of solar heat energy absorbed is controlled, and the purpose of controlling the body temperature is finally achieved. The invention designs a hydraulic retarder rotor structure capable of automatically adjusting the blade inclination angle according to the strength of a signal received by a sensor on the basis of the action mechanism of the bionic butterfly scale.
