Abstract
The utility model is related to a kind of safety clutch formula electric compressor, power-assisted steering oil pump all-in-one machines, belong to the power saving features on new-energy automobile.Driving motor one end output shaft is keyed with power-assisted steering oil pump, and the other end output sleeve of the driving motor and the outer shroud of safety clutch device connect, and the inner ring of safety clutch device and the axle key of air compressor connect.Advantage is:Structure novel, can stop operating in air compressor machine failure or when driving motor inverts protects air compressor machine, reduce cost depletions when fault of integrated;Straight line is arranged in order for air compressor, safety clutch device, driving motor and power-assisted steering oil pump, and layout integrated level is high, light-weight, small, is accomplished to mitigate light weight, is simplified vehicle arrangement, saves Bus inner layout space, effectively reduces vehicle energy consumption.
Description
Technical field
The utility model belongs to power saving features more particularly to a kind of electric air press, power-assisted turn on new-energy automobile
To oil pump all-in-one machine.
Background technology
Since 21 century, social progress is along with the development of New Energy Industry, new energy vapour with the development of economy
Vehicle has gradually come into the visual field of people, and the development of new-energy automobile has become the certainty of history.Currently, being applied to new energy vapour
Electric air compressor, power-assisted steering oil pump all-in-one machine on vehicle, structure are that a driving motor drives electronic pneumatics simultaneously
Machine, power-assisted steering oil pump, can meet the air pump during normal vehicle operation inflate, power-assisted steering work.But when air compressor machine goes out
Existing failure, when pneumatics arbor is stuck, driving motor is by related stuck cisco unity malfunction, therefore power-assisted steering oil pump also can not be normal
Work, vehicle can not be completed to turn to pulling over observing work, be easy to happen traffic accident.In addition, air compressor machine is screw air compressor,
Screw deadlocking, air compressor machine failure are be easy to cause when reversion.
Invention content
A kind of safety clutch formula electric compressor of the utility model offer, power-assisted steering oil pump all-in-one machine, it is existing to solve
All-in-one machine in electric compressor failure when, influence steering pump work the problem of.
The technical scheme adopted by the utility model is that:Driving motor one end output shaft is keyed with power-assisted steering oil pump, should
The other end output sleeve of driving motor and the outer shroud of safety clutch device connect, and inner ring and the air of safety clutch device compress
The axle key of machine connects.
The safety clutch device includes outer shroud, inner ring, support spring and latch, and support spring both ends are separately connected interior
Ring and latch, latch one end are clamped with the locking groove on inner ring rotation connection, the other end and outer shroud.
Protective cover is mounted on outside safety clutch device.
The utility model has the advantages that:Structure novel passes through axis and key connection between air compressor and driving motor
Safety clutch device, the safety clutch device are a kind of to utilize the variation of the relative rotation speed of driving motor and air compressor machine or revolution side
To transformation, the clutch that engages and disengage automatically is normal operating conditions when driving motor drives air compressor machine to rotate together;
When air compressor machine failure stops operating, driving motor voluntarily operates, and does not influence power-assisted steering oil pump normal work;When such as reversion,
Guard mode can then be entered;Driving motor is protected in air compressor machine failure, air compressor machine can be also protected when driving motor inverts, no
Air compressor machine is damaged, cost depletions when fault of integrated are reduced;Air compressor, safety clutch device, driving motor and power-assisted
Steering pump in order arrange by straight line, and layout integrated level is high, light-weight, small, accomplishes to mitigate light weight, simplifies vehicle cloth
It sets, save Bus inner layout space, effectively reduce vehicle energy consumption.

Fig. 2 is the structural schematic diagram of the utility model safety clutch device;
When Fig. 3 is that utility model works are normal, the state diagram of safety clutch device;
Fig. 4 is the utility model air compressor machine failure, when pneumatics arbor is stuck, the state diagram of safety clutch device;
When Fig. 5 is the reversion of the utility model driving motor, the state diagram of safety clutch device.
Specific implementation mode
4 one end output shaft of driving motor is keyed with power-assisted steering oil pump 5, the other end output sleeve of the driving motor 4
It is connect with the outer shroud 301 of safety clutch device 3, the inner ring 302 of safety clutch device 3 is connect with the axle key of air compressor;
The safety clutch device 3 includes outer shroud 301, inner ring 302, support spring 303 and latch 304, support spring
303 both ends are separately connected inner ring 302 and latch 304,304 one end of latch and the rotation connection of inner ring 302, the other end and outer shroud
Locking groove clamping on 301;
Protective cover 2 is mounted on outside safety clutch device 3.
Operation principle:As shown in Fig. 2, safety clutch device outer shroud 301 carries locking groove, outer shroud 301 and drive motor shaft
Set connection, inner ring 302 and air compressor machine axis connection, when air compressor machine does not break down, and driving motor runs well, latch 304
In locking groove, driving motor band engine-driven air compressor operates, and working properly, safety clutch device status is as schemed at this time
Shown in 2;When air compressor failure, when air compressor axis is stuck, inner ring 302 is static, and driving motor outputting torsion is more than only
Dynamic slot is applied to the stopping power of latch 304, and latch glides at this time, compresses support spring 303,301 phase of inner ring 302 and outer shroud
To being detached from, outer shroud 301 remains in operation under the drive of driving motor axle sleeve, and driving motor can drive power-assisted steering oil pump just at this time
Often work, safety clutch device status are as shown in Figure 4;When installation and debugging the utility model, such as artificial patching operations
It is improper, when driving motor being caused to invert, drive motor shaft set drive outer shroud 301 rotate backward, latch 304 along stop trough rim from
By gliding, 301 relative separation of inner ring 302 and outer shroud, inner ring 302 rotates backward under the limitation of pneumatics arbor, not, plays guarantor
The effect of air compressor is protected, safety clutch device status is as shown in Figure 5 at this time.
