Abstract
The invention provides a pneumatic clutch control type permanent magnetism retarder, which relates to a permanent magnetism retarder which comprises a stator and a rotor, wherein, the stator comprises a stator frame, a magnet support, a magnet external holder, a permanent magnet; the rotor comprises a rotor disk and a flange, and the rotor disk and the flange are connected by a clutch device which has the same axis with the rotor disk; the permanent magnet is fixed on the magnet support. Under the normal driving state of a vehicle, the rotor disk does not rotate, does not generate eddy current which hinders the movement of a transmission shaft and does not generate heat. When speed is need to be lowered, the pneumatic clutch starts to work and the rotor disk rotates to realize speed slowing. By utilizing the pneumatic clutch to carry out control, the rotor does not rotate under non-working sate; therefore, the invention has the advantages of requiring no degaussing, no reverse braking torque when in no braking state, energy-saving, large torque moment, high reaction speed, compact structure, safety and long service life.
Description
Technical field
The present invention relates to automobile retarder, relate in particular to a kind of permanent-magnet speed buffer.
Background technology
Automobile retarder is the many a kind of automobile brake auxiliary devices of domestic in recent years use, and at present mainly based on current vortex retarder, other forms of retarder has Retarder, permanent-magnet speed buffer, generator-type retarder, exhaust brake retarder etc.Wherein permanent-magnet speed buffer in light weight with it, do not consume energy, advantage such as lossless, non-maintaining and be subjected to user's favor gradually.
Permanent-magnet speed buffer is the upgrading products of current vortex retarder, and it utilizes permanent magnet to replace utilizing in the current vortex retarder coil to produce magnetic field with iron core.Rotor disk rotates cutting magnetic line, and produces current vortex, produces braking moment, and realizes the purpose of braking.
The permanent-magnet speed buffer of home and overseas all is the mode that adopts demagnetization at present, realize not working of retarder, the mode of demagnetization generally all be magnet produce to be moved or dislocation after, with magnetic material the magnetic line of force is masked, and the purpose of realization demagnetization, the rotor cutting does not produce moment less than the magnetic line of force.It is to utilize the impetus of cylinder to come the interior magnet of mobile device, thereby whether the demagnetization of controlling magnet is to realize permanent-magnet speed buffer work.Limited in view of the motive force of cylinder, limited mainly due to the bleed pressure that automobile can provide, structure space restriction makes the cylinder diameter of cylinder can not be too big in addition.The reaction of cylinder simultaneously is slower, and the permanent-magnet speed buffer that can not adapt to the requirement of automobile brake, particularly high pulling torque is all the more so.In addition, there is leakage field phenomenon (demagnetization is unclean) in this permanent-magnet speed buffer, when not needing to brake, still has plugging moment, causes the automobile energy consumption to increase, and oil consumption is many, makes numerous drivers be reluctant to use.
Summary of the invention
The present invention is directed to above variety of problems and provide that a kind of rotor disk does not rotate under the normal vehicle operation state, thereby do not produce the Pneumatic clutch controlling permanent magnetic retarder of current vortex.
Technical scheme of the present invention is: it comprises stator and rotor, stator comprises stator frame, magnet holder, the outer retainer of magnet, permanent magnet, rotor comprises rotor disk, flange, and rotor disk is connected by arrangement of clutch with flange, described arrangement of clutch and rotor disk coaxial line; Permanent magnet is fixedly connected on the magnet holder.
Described arrangement of clutch is made up of source of the gas, cylinder barrel, piston, friction plate gland, back-moving spring, friction steel disc, friction plate, clutch support, rotor field spider; Cylinder barrel is fixedly connected on the magnet holder of stator, and cylinder barrel is established air inlet towards a side of stator support, and the opposite side of cylinder barrel is established piston, piston is a ring-type, be provided with step circle, establish the friction plate gland in the osculum of step circle, establish the axial thrust ball between step nose circle face and the friction plate gland; The friction plate gland is the step tubular, is located in the tube with the vehicular transmission shaft flange connecting, and back-moving spring is located between friction plate gland and the end face of flange, and flange is fixedlyed connected with the clutch support, and the clutch mid-stent is provided with a circle flange; Friction plate gland tube port position is established a circle flange; The flange end face correspondence is provided with the friction steel disc; With the corresponding friction plate that is provided with of friction steel disc, friction plate is connected on the flange of clutch support; Clutch is propped up and is erected in the tubular rotor field spider, and both are rotationally connected.
The present invention is provided with arrangement of clutch between rotor disk and flange, make vehicle under the cruising state, and rotor disk does not rotate, and does not produce the current vortex that hinders the power transmission shaft motion, also can not generate heat.When needs are slow, the work of air clutch device, rotor disk rotates, and realizes slow.Overcome present permanent-magnet speed buffer and had leakage field phenomenon (demagnetization is unclean), when not needing to brake, still had plugging moment, caused the automobile energy consumption to increase, the problem that oil consumption is many.The present invention utilizes pneumatic clutch to control, and rotor does not rotate when non operating state, has the demagnetization of need not, and does not have plugging moment when not braking, the effect energy-conservation, that moment of torsion is big, reaction speed is fast, compact conformation, safety, use birthday noodle are long.
