Problems solved by technology

[0002] Since the birth of automobiles, human beings have never stopped studying the clutches of automobiles. People have developed a variety of automobile clutches. Modern commonly used clutches mainly include friction clutches, hydraulic coupling clutches, electromagnetic clutches, etc., but these Clutches cannot achieve the high transmission efficiency of gear transmission; Wei Boqing's invention patent "201510001309.7 Screw Spring Clutch" is cleverly designed, but it is greatly affected by the centrifugal force of rotation, that is, when the rotation speed of the driven wheel is high, the driven wheel drives The small magnetic block in the rotating wheel may accidentally close the clutch due to excessive centrifugal force. Although Wei Boqing's invention patent "201510042453.5 Side Control Screw Spring Clutch" has improved this, the improved magnetic block is in the process of clutch separation. In the state, it is adsorbed on the outer surface of the rotating wheel, so that the magnetic attraction force of the semicircular barrel magnetic tile is very large when the clutch is closed, which brings difficulties to the miniaturization of the clutch. The present invention strives to make greater improvements to these defects, namely Combining the screw and the spring ingeniously and using the principle of magnetic repulsion, the magnetic repellent block installed on the side of the rotating wheel driven by the driven wheel pushes the magnetic repelling block of the semi-circular barrel magnetic tile to the axis of the rotating wheel, so that the opening and closing of the clutch device does not stop. Affected by centrifugal force, it forms a non-contact, spring-buffered, non-obvious clutch that transmits power as efficiently as gear transmission efficiency. The synchronizer used in this invention can also use Wei Boqing's latest invention "201510055279.8 screw rod Magnetic Repulsion Synchronizer》
