Spring clutch of laterally controlled screw

Abstract

The invention discloses a spring clutch of a laterally controlled screw. The clutch comprises a driven shaft with a strip of outer thread and a driven shaft wheel screwed on the driven shaft, wherein a driven free wheel sleeves the center of the periphery of the driven shaft wheel; the periphery of the driven shaft wheel at one side of the driven free wheel is symmetrically provided with a plurality of clutch crank arm wheels; the left side of the driven shaft wheel is provided with a left auxiliary wheel, a left buffer wheel, a left blocking wheel and a left spring; the right side of the driven shaft wheel is provided with a right auxiliary wheel, a right buffer wheel, a right blocking wheel and a right spring, and a semicircular barrel magnetic shoe is arranged at one side, far away from a driving wheel, of the driven free wheel; the clutch is characterized in that the driven free wheel is installed in the center of the periphery of the driven shaft wheel; a plurality of driven free wheel side slots are formed in one side of the driven free wheel symmetrically, and one sides of the driven free wheel side slots are symmetrically provided with the plurality of clutch crank arm wheels; one end of each clutch crank arm is provided with a small roller shaft of the clutch crank arm and a small roller wheel of the clutch crank arm, and the other end of each clutch crank arm is provided with a clutch crank arm rail rod; the left side of each clutch crank arm rail rod is provided with a left tail fin of the clutch crank arm, and the right side of each clutch crank arm rail rod is provided with a right tail fin of the clutch crank arm.

Description

technical field [0001] The invention relates to a side control screw spring clutch, which is suitable for clutch transmissions of all automobiles and belongs to the technical field of automobile transmissions. Background technique [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.

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. The present invention makes corresponding improvements to the above defects. Based on Wei Boqing's invention patent "201510000063.1 Screw Spring Synchronizer", the use The screw and the spring are ingeniously combined and the clutch device is installed on the side of the rotating wheel driven by the driven wheel by using the principle of magnetic attraction. Excessive centrifugal force will cause the magnetic block to be thrown out and the clutch device will be closed unexpectedly, thus forming a non-contact, spring-buffered, non-obvious clutch that transmits power as efficiently as gear transmission efficiency
