Magnetic side pressure internal control screw spring clutch

Abstract

A magnetic side pressure internal control screw spring clutch comprises a driven shaft with an external thread and a driven shaft wheel screwed on the driven shaft. The outer portion of the center of the outer circumference of the driven shaft wheel is sleeved with a driven free wheel, a plurality of clutch magnetic blocks are symmetrically installed on the outer circumference of the driven shaft wheel on one side of the driven free wheel, each clutch magnetic block is connected with a clutch seesaw device through a clutch seesaw cross rod, each clutch seesaw device is provided with a clutch seesaw wheel in an inner ring surface area of the driven free wheel, and a plurality of driven free wheel inner grooves matched with the clutch seesaw wheel are formed in the inner ring surface of the driven free wheel. Auxiliary wheels, buffer wheels, blocking wheels and springs are positioned on the left side and the right side of the driven shaft wheel, and a semicircular barrel magnetic shoe is installed on one side of the driven free wheel far away from a driving wheel. The magnetic side pressure internal control screw spring clutch is characterized in that the inner diameters, the number and the distribution of the driven free wheel inner grooves correspond to and are matched with the outer diameters, the number and the distribution of the clutch seesaw wheels.

Description

technical field [0001] The invention relates to a magnetic lateral pressure internal 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.

[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 wheel of the clutch device is installed on the inner ring surface of the passive movable wheel driven by the driven shaft wheel by using the magnetic repulsion principle. The outer peripheral surface of the shaft wheel, through the action of the clutch seesaw lever, keeps the clutch seesaw wheel away from the inner ring surface of the passive live wheel, so that the centrifugal force is too large and the clutch wheel is accidentally closed, thus forming a non-contact, spring-loaded Cushioned, non-frustrating clutch that transmits power as efficiently as gears
