Description

Safety clutch formula electric compressor, power-assisted steering oil pump all-in-one machine

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.

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.
