Description
Technical field
The utility model is related to the radial friction formula clutch that a kind of plunger case pushes taper guide rail, the utility model can answer
In the driving of full-sized car or engineering truck brake system air compressor.
Background technology
Using the automobile of air-pressure brake, needed during automotive service by gas compression into gas receiver, in vehicle system
Brake circuit is driven when dynamic, is generally completed by the power source drives air compressor such as engine, the power sources such as engine and air
The connections such as leather machine belting are compressed, the power sources such as engine are started to work, and air compressor follows work.In use above,
It can be seen that power source is kept in motion always, the power of power source is continually taken, it, can not be by it when not needing the work of power source
It is thoroughly cut off with power source, if air compressor is when gas receiver reaches target air pressure, circuit and big gas phase will be inflated by valve
Even, make air compressor unloaded operation, but the abrasion of air compressor internal friction loss of energy and element can not be eliminated.Especially
In today of the increasingly leading automobile market of new-energy automobile, how thoroughly eliminating the waste of unnecessary energy, reducing discharge is base
The starting point and foothold of this structure design.
The clutch applied in machinery industry at present according to《Chinese clutch manufacturing production and marketing demand and investment forecasting point
Analysis report prediction》Four kinds of electromagnetic clutch, magnetic powder cluth, friction clutch and fluid clutch can be divided into.Wherein, electromagnetism from
Clutch is that the engagement and separation of clutch are controlled by the power on/off of coil：When coil is powered, magnetic force is generated, by frictional disk
Passing power is compressed, when coil blackout, magnetic force disappears, and frictional disk separation cuts off power, this is switched on engagement type electromagnetic clutch
Device can also manufacture power-off engagement type electromagnetic clutch according to demand；Magnetic particle coupling is put between driving link and driven member
Set magnetic material, when energization, driving link, magnetic material, driven member are connected as rigid body, and passing power can control the big of electric current
It is small, to carry out the differential gearing between driving part and slave unit；Slip clutch quotes most wide clutch at present, by
Active part, secondary part, hold-down mechanism and operating mechanism composition, control actuating element offset the pressing force of hold-down mechanism, often
State is engagement state；Fluid clutch, as driving medium, is pumped out by pump impeller using fluid and is transferred to impeller reality by guide wheel
The transmission of existing power, does not need control mechanism.In terms of the structure & working mechanism of above four kinds of clutches, electromagnetic clutch and magnetic
Powder clutch has portable construction, controls simple advantage, using energization engagement type, is arranged in vehicle chassis, can meet with
On design requirement, but two kinds of clutches do not have fail safe measure, and it is not to apply this security fields in automobile brake
Can with；And traditional clutch is that normal engagement state works with fluid clutch, can not meet use and design requirement.This
Utility model mainly reaches the requirement of normal mask work state between power source and air compressor, and operating mechanism power takes
From air compressor itself, it is not necessarily to accessory power supply, and there is fail safe function.
In conclusion power source carries out connection when necessary with air compressor, and when air pressure reaches setting target, cut-out
Connection between power source and air compressor saves power source and consumes energy, reduce motor element fretting wear, improves component
The service life of system is should mainly to solve the problems, such as at present, while considering that control section simplifies as possible, reliability and durability；Have
Fail safe function；The relevant issues such as control cost have realistic meaning.
Invention content
Technical problem to be solved in the utility model is：On the one hand, existing clutch such as electromagnetic clutch cost is solved
Height, is risen big using process medium temperature, and additional supply is needed to be driven, such as slip clutch and fluid clutch volume is big, cloth
Inconvenience is set, parasitic loss is big, the problems such as cannot simply changing the state that it is often engaged；On the other hand, it is more suitable for new energy
The use of source automobile, rationally takes the power of driving motor, and the towing astern from wheel drive system can drive sky when vehicle braking
