Abstract
A kind of annular magnet permanent-magnet clutch for automobile, its structure is made up of driving shaft, flywheel, fixed disk, driving disc spacing pressing, driven shaft, clutch plate, magnet, magnetic conductive disk, release bearing, shift fork, spring, bell housing.During internal combustion engine, flywheel drives fixed disk, driving disc spacing pressing and magnetic conductive disk to rotate; When not stepping on clutch, magnetic conductive disk is in right position; Magnetic force initiatively between magnetic conduction ring gear, clutch plate magnetic inductive block, fixed disk magnetic teeth air gap is large, and the power of flywheel passes on clutch plate by magnetic force, is equivalent to clutch " conjunction ".When stepping on clutch, shift fork and release bearing promote separator levers to the right, make magnetic conductive disk be in left position; Magnetic conductive disk is positioned at magnet and driving disc spacing pressing reduced diameter section place, forms closed magnetic circuit between magnet, magnetic conductive disk and driving disc spacing pressing, and the magnetic line of force that magnet produces enters driving disc spacing pressing through magnetic conductive disk; The magnetic line of force initiatively between magnetic conduction ring gear, clutch plate magnetic inductive block, fixed disk magnetic teeth air gap is little, and the power of flywheel can not pass on clutch plate by magnetic force, is equivalent to clutch "Off".
Description
Technical field
The utility model relates to the clutch in a kind of car transmissions.
Background technology
All clutch is housed between car combustion engine and speed changer, generally adopts friction-type; But this clutch wear and tear in use than very fast, the life-span is shorter.For this reason, people have devised magnetic gear; General employing arc magnetic pole is alternately arranged, this kind of clutch magnet manufacture and installation inconvenience.
Utility model content
The purpose of this utility model is to provide a kind of annular magnet permanent-magnet clutch for automobile; The magnet of this clutch is annular; Be placed in driving disc spacing pressing, by the trend of the Position Control magnetic line of force at the magnetic conductive disk place of annular, change the magnetic force size between clutch plate and driving disc spacing pressing, realize clutch.Because the air gap between driving disc spacing pressing and clutch plate is very little, and multiple air gap can be formed; Thus large moment can be transmitted.
Structure of the present utility model is made up of driving shaft, flywheel, fixed disk, driving disc spacing pressing, driven shaft, clutch plate, magnet, magnetic conductive disk, release bearing, shift fork, separator levers, spring and bell housing.Wherein fixed disk is annular, is screwed on flywheel; Fixed disk left side is shaped with the equally distributed fixed disk magnetic teeth of a circle.Driving disc spacing pressing is stepped drum-shaped, is screwed on fixed disk; For stationary annular magnet and active magnetic conduction ring gear, and as yoke; Separator levers is installed in driving disc spacing pressing left side.Magnet is annular or watt shape, radial magnetizing; Be bonded in driving disc spacing pressing, for generation of magnetic field.Initiatively magnetic conduction ring gear is annular, and end face is shaped with a circle and is uniformly distributed the tooth identical with the fixed disk magnetic conduction number of teeth.Clutch plate is disc, uses non-magnet material manufacture, is loaded on driven shaft by spline; It is shaped with a circle and is uniformly distributed the clutch plate magnetic inductive block equal with the fixed disk magnetic conduction number of teeth; Clutch plate magnetic inductive block is corresponding with the tooth of fixed disk magnetic teeth and active magnetic conduction ring gear, and forms air gap.Magnetic conductive disk is disc, and external diameter is with magnet, driving disc spacing pressing reduced diameter section and initiatively magnetic conduction ring gear internal diameter is identical; And can slide between three.Adjustment bolt one end is fixed on magnetic conductive disk, and the other end is through the hole on driving disc spacing pressing left side; For pulling the position of magnetic conductive disk and restriction magnetic conductive disk, ensureing magnetic conductive disk and initiatively having suitable gap between magnetic conduction ring gear.Spring housing is on adjustment bolt, and spring is between driving disc spacing pressing end face and magnetic conductive disk; Spring force makes magnetic conductive disk be in right position.Shift fork and release bearing are used for promoting separator levers to the right, make magnetic conductive disk pull to left position.
Operation principle: during internal combustion engine, flywheel drives fixed disk, driving disc spacing pressing and magnetic conductive disk to rotate; When not stepping on clutch, spring force makes magnetic conductive disk be in right position, and magnetic conductive disk is positioned at magnet, initiatively magnetic conduction ring gear place; Closed magnetic circuit is formed between magnet, magnetic conductive disk, active magnetic conduction ring gear, clutch plate magnetic inductive block, fixed disk magnetic teeth, fixed disk and driving disc spacing pressing.Magnetic force initiatively between magnetic conduction ring gear, clutch plate magnetic inductive block, fixed disk magnetic teeth air gap is large, and the power of flywheel passes on clutch plate by magnetic force, is equivalent to clutch " conjunction ".When stepping on clutch, shift fork and release bearing promote separator levers to the right, and magnetic conductive disk is pulled to left position; Magnetic conductive disk is positioned at magnet and driving disc spacing pressing reduced diameter section place, forms closed magnetic circuit between magnet, magnetic conductive disk and driving disc spacing pressing, and the magnetic line of force that magnet produces enters driving disc spacing pressing through magnetic conductive disk and forms magnetic loop; The magnetic line of force initiatively between magnetic conduction ring gear, clutch plate magnetic inductive block, fixed disk magnetic teeth air gap is little, and the power of flywheel can not pass on clutch plate by magnetic force, is equivalent to clutch "Off".
Magnet due to annular magnet permanent-magnet clutch for automobile is watt shape of annular or negligible amounts, installs and convenient fixing, and initiatively forms two small air gaps between magnetic conduction ring gear, clutch plate magnetic inductive block, fixed disk magnetic teeth, can improve the transmission capacity of clutch.
