Compression spring type buffer friction gear meshing clutch

Abstract

A compressed spring type buffer friction gear meshed clutch comprises a driving shaft, a driving wheel, a driven wheel and a set of engaged wheels, wherein the driving shaft is sleeved with the driving wheel, the driven wheel and the engaged wheels, and the engaged wheels are arranged between the driving wheel and the driven wheel. The clutch is characterized in that the engaged wheel set comprises a long bearing, a left engaged wheel, a right engaged wheel, a left engaged wheel left spring and a spring between the left engaged wheel and the right engaged wheel, wherein the left engaged wheel, the right engaged wheel, the left engaged wheel left spring and the spring are arranged on the long bearing, and the spring between the left engaged wheel and the right engaged wheel is implemented according to three schemes. According to the first scheme, the large spring is arranged between the left engaged wheel and the right engaged wheel; according to the second scheme, a plurality of small springs are arranged between the left engaged wheel and the right engaged wheel, and are symmetrically arranged around the long bearing; according to the third scheme, a spring set composed of a left spring and a right spring is arranged between the left engaged wheel and the right engaged wheel, the left spring and the right spring are arranged in series connection, and the winding directions of the left spring and the right spring are opposite; the long bearing is arranged on the driving shaft, and the long bearing can rotate around the axial line of the driving shaft but cannot move along the axial line of the driving shaft.

Description

technical field [0001] The invention relates to a compression spring type cushioning friction gear meshing clutch, which is suitable for various mechanisms requiring clutch speed change and clutch speed regulation, such as clutch speed change devices of various vehicles, gearboxes of lathes, etc., and belongs to the technical field of clutch and gear transmission. Background technique [0002] Today's automobile clutches include friction clutches, hydraulic couplings, and electromagnetic clutches. They all use soft contact, that is, friction, hydraulic force, or electromagnetic force, to transmit the rotational power of the engine. The power transmission efficiency of these soft contacts is relatively high. Low; the reason why the modern developed automobile industry still uses the soft contact clutch method with low power transmission efficiency is because the meshed gears are difficult to separate when the gear meshing transmission rotates at high speed, and no hard transmi...

Problems solved by technology

[0002] Today's automobile clutches include friction clutches, hydraulic couplings, and electromagnetic clutches. They all use soft contact, that is, friction, hydraulic force, or electromagnetic force, to transmit the rotational power of the engine. The power transmission efficiency of these soft contacts is relatively high. Low; the reason why the modern developed automobile industry still uses the soft contact clutch method with low power transmission efficiency is because the meshed gears are difficult to separate when the gear meshing transmission rotates at high speed, and no hard transmission that is easy to mesh has not been found yet. The gear separation and gear meshing transmission method with higher transmission efficiency is a difficult problem in improving the transmission efficiency of automobiles; although Wei Boqing's invention patent "201410151795.6 Threaded Sleeve Clutch" can achieve high-efficiency transmission of gear clutch meshing, but its There is an intermediate driven wheel with a relatively wide structure and relatively large volume, and the clutching process in Wei Boqing's other invention "201410162087.2 Spring Pressure Friction Gear Engagement Clutch" also has a certain frictional impact effect. The effect of compression, twisting and buffering realizes the high-efficiency transmission structure of gear clutch meshing with small clutch impact
