A kind of overrunning clutch with speed control power master-slave commutation

Abstract

The invention provides an overrun clutch achieving rotating speed control drive and driven power reversing. The overrun clutch is formed by combining two sets of pin roller overrun clutch bodies. An inner ring base and an outer ring base of the first set of pin roller overrun clutch body are fixedly combined with an outer ring base and an inner ring base of the second set of pin roller overrun clutch body respectively. In the initial stage, pin rollers of the two sets of pin roller overrun clutch bodies make contact with and separate from the inner walls of the outer ring bases through springs respectively. The clutch works in a low-speed state, a middle-speed state and a high-speed state. At the low speed, a drive mechanism drives a driven mechanism to rotate through the first set of pin roller overrun clutch body. At the middle speed, the speed of the driven mechanism is increased to exceed the speed of the drive mechanism, and the pin roller overrun clutch bodies are in a separation state. At the high speed, the speed of the driven mechanism is higher than that of the drive mechanism, the second set of clutch body works and reversely drags an original drive mechanism, and power reversing is achieved. The clutch can be applied to the aspects such as electric cars and engine turbine supercharging systems, the performance of a car is improved under driving of a motor at the low speed, the motor is reversely dragged for power generation to achieve energy saving at the high speed, and it is guaranteed that the mechanisms run within the appropriate speed range.

Description

technical field [0001] The invention relates to an overrunning clutch, which can realize the function of changing the power transmission direction as the rotation speed changes. Background technique [0002] The upper assembly mechanism of the car usually has the best speed for operation, such as exhaust gas turbocharging. Too high or too low speed will be very unfavorable to the structure or performance of the mechanism. If a mechanism can be developed so that a similar assembly can input power from the outside at low speeds and output power to the outside at high speeds, it will not only improve the operating efficiency and service life of the mechanism, but also effectively save energy and improve the economic performance of the car. [0003] The overrunning clutch is a basic component that appears with the development of mechatronics products. It is an important component used for power transmission and separation between the prime mover and the working machine or betwe...

Problems solved by technology

However, the current overrunning clutches are all one-way power transmission mechanisms, which cannot realize the above-mentioned functions (can input power from the outside at low speeds, and output power to the outside at high speeds).
