Magnetically-controlled side pressing type screw rod and spring clutch

Abstract

The invention relates to a magnetically-controlled side pressing type screw rod and spring clutch, which comprises a driven shaft and a driven shaft wheel, wherein the driven shaft is provided with external threads, the driven shaft wheel is screwed onto the driven shaft, a driven movable wheel sleeves the exterior of the center of the outer circumference of the driven shaft wheel, a plurality of clutch crank arm wheels are symmetrically arranged at the outer circumference of the driven shaft wheel at one side of the driven movable wheel, a left auxiliary wheel, a left buffering wheel, a left retaining wheel and a left spring are arranged at the left side of the driven shaft wheel, a right auxiliary wheel, a right buffering wheel, a right retaining wheel and a right spring are arranged at the right side of the driven shaft wheel, and a semicircular bucket magnetic bearing is arranged at one side, away from a driving wheel, of the driven movable wheel. The magnetically-controlled side pressing type screw rod and spring clutch is characterized in that the driven movable wheel is arranged at the center of the outer circumference of the driven shaft wheel, a group of bearings are arranged at an inner ring of the driven movable wheel and are connected with the driven shaft wheel, the driven movable wheel side grooves are symmetrically formed in one side of the driven movable wheel, each clutch crank arm wheel is provided with a clutch crank arm lower spring, a clutch crank arm small roller shaft and a clutch crank arm small roller are arranged at one side surface, near the driven movable wheel, of each clutch crank arm, and the number of the clutch crank arm small rollers is matched with the number of the driven movable wheel side grooves in the side surface of the driven wheel.

Description

technical field [0001] The invention relates to a magnetically controlled lateral pressure 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...

[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
