Abstract

The invention relates to a one-way transmission device with a buffer function. A first friction ring and a second friction ring are respectively connected with an inner ring assembly and an outer ring assembly through a reinforcement transmission mechanism and a conical face friction pair in matching mode, wherein the inner ring assembly and the outer ring assembly can rotate around the same axis, the reinforcement transmission mechanism is in a constant meshed state, and the conical face friction pair exerts initial pressure through an elastic pre-tightening piece. When tangential external component force in different directions appears between the inner ring assembly and the outer ring assembly, under the effect of the reinforcement transmission mechanism, the conical face friction pair rotates in sliding mode or keeps a static state, and therefore the unidirectional transmission torque function similar to an overrun clutch is achieved. In addition, the one-way transmission device has excellent buffer performance, effectively buffers various impact force in the process of mechanical transmission and prolongs service life of a transmission system.

Description

technical field [0001] The invention relates to a transmission wheel in the field of mechanical power transmission, especially a one-way transmission device with a buffer function, such as a belt pulley, a sprocket, a gear, a flange, etc., which is a basic functional component widely used in mechanical transmission. [0002] Background technique [0003] The existing one-way transmission device with a buffer function, such as a pulley, is provided with a belt loop groove that matches the belt, and the power of the engine is input to the driven wheel through the belt, and the driven wheel drives the output shaft to transmit the power to the corresponding connected parts. Mechanical devices that use sprockets, gears, etc. to transmit power are basically the same or similar to pulley drives. [0004] In the power plant that uses a pulley drive engine, such as German cars, European and American cars, Japanese and Korean cars, because the instantaneous speed of the engine fluct...
