For making those skilled in the art be better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings
With detailed description of the invention, this utility model is elaborated.
As it is shown in figure 1, embodiment of the present utility model discloses a kind of driving clutch, this driving clutch
Device for sending the compressor of air conditioner of hybrid vehicle to by power, and this driving clutch is arranged on support
On 12, this support 12 can be fixed on the fixed structures such as electromotor or the vehicle frame of hybrid vehicle, should
Support 12 forms a mandrel (or claiming support shaft), and need to make this mandrel and the output shaft of electromotor and electricity
The output shaft of machine is parallel.Driving clutch of the present utility model include first belt wheel the 1, second belt wheel 2 with
And rubber blanket 6；By clutch shaft bearing 10, (clutch shaft bearing 10 is axially limited first belt wheel 1 by jump ring 11
Position) it is arranged on the mandrel of support 12, this first belt wheel 1 is by first belt and compressor of air conditioner
Connecting, the second belt wheel 2 is arranged on the mandrel of support 12 by the second bearing 9, this second belt wheel 2
It is connected with electromotor by another root second belt, and the second belt wheel 2 carries with first in the axial direction of mandrel
Wheel 1 interval, rubber blanket 6 is arranged on the first belt wheel 1 or between the first belt wheel 1 and the second belt wheel 2,
Rubber blanket 6 is for buffering the first belt wheel 1 when the state that the first belt wheel 1 is in the second belt wheel 2 is combined
With the second belt wheel 2 play in the axial direction.
Owing to being provided with rubber blanket 6 on driving clutch of the present utility model so that the first belt wheel 1 He
Second belt wheel 2 is when because of certain external force generation axial float, and rubber blanket 6 can effectively buffer play, from
And greatly reduce the noise and abrasion produced because of play impact.
In a preferred embodiment of the present utility model, driving clutch also includes the 3rd belt wheel and control
Assembly；3rd belt wheel 3 is connected with motor by the 3rd root bark band, and the 3rd belt wheel 3 with the first belt wheel
1 mode rotated coaxially is arranged；Controlling assembly and include frictional disk 5 and coil assembly 4, frictional disk 5 is positioned at
Between first belt wheel 1 and the second belt wheel 2, and arranging in the way of with the first belt wheel 1 rotation, coil is total
Become 4 to be fixed on the second belt wheel 2, when coil assembly 4 is energized, produce electromagnetic force can attract to rub
Wiping dish 5, now rubber blanket 6 deforms, and when coil assembly 4 power-off, rubber blanket 6 restores to drive
Frictional disk 5 resets.So, when needing electromotor as the power source of compressor of air conditioner, wire harness is passed through
41 are energized to coil assembly 4, attract frictional disk 5 and make frictional disk 5 and second after coil assembly 4 energising
Belt wheel 2 combines, so that the first belt wheel 1 rotates with the second belt wheel 2, and then by the output shaft of electromotor
Power pass sequentially through second belt wheel the 2, first belt wheel 1 and pass to compressor of air conditioner, finally make air-conditioning pressure
Contracting machine works.When needing motor as the power source of compressor of air conditioner, make coil assembly 4 power-off, rub
Wiping dish 5 separates with the second belt wheel 2, and the power of the output shaft of motor passes sequentially through the 3rd belt wheel 3, first
Belt wheel 1 passes to compressor of air conditioner, and now, if electromotor is in running order, the second belt wheel 2 dallies
(the first belt wheel 1 and the second each autorotation of belt wheel 2, be independent of each other), if electromotor is not actuated, the second band
Wheel 2 holding resting state.
Driving clutch of the present utility model may utilize different dynamic source and drives compressor of air conditioner, and power source
Between switching simple, it is often more important that: when electromotor is the most not actuated, can be by motor
Power is provided for compressor of air conditioner as power source.
In a preferred embodiment of the present utility model, one end that the first belt wheel 1 is relative with frictional disk 5
Being formed with connection dish 14, rubber blanket 6 is fitted on the connection dish 14 side away from frictional disk 5, rubber

And rotate with the first belt wheel 1, as it is shown in figure 1, in a preferred embodiment of the present utility model, the
Three belt wheels 3 are one-body molded with the first belt wheel 1, are i.e. processed into two belt grooves on a wheel shaft side by side and shape
Become this first belt wheel 1 and the second belt wheel 2, thus eliminate and the first belt wheel 1 is installed with the 3rd belt wheel 3
Assembly process together.
When coil assembly 4 power-off, for quickly eliminating the electromotive force in coil assembly 4, and then make coil
Assembly 4 quickly loses the electromagnetic force attracting frictional disk 5, electrically connects diode on coil assembly 4, by
Existence in diode makes the coil assembly 4 of power-off quickly lose electromagnetic force, and the first belt wheel 1 can be fast
Speed separates with the second belt wheel 2.
In a preferred embodiment of the present utility model, coil assembly 4 is electrically connected with thermal fuse,
When temperature raises because of " skidding " for frictional disk 5 and the second belt wheel 2, for protecting this driving clutch,
Thermal fuse fuses, coil assembly 4 power-off, and the first belt wheel 1 realizes separating with the second belt wheel 2.
In a preferred embodiment of the present utility model, at the second belt wheel 2 away from one end of frictional disk 5
Offering and be formed with cannelure, coil assembly 4 is installed in cannelure, and the installing mode of coil assembly 4 makes
Obtain driving clutch compact conformation.
Driving clutch of the present utility model not only can switch power source, it is also possible to by the power of electromotor
Pass to motor, e.g., when the motor being to can be used as power source selected by motor, again can be as electromotor
Type time, this motor electrically connects accumulator again, when coil assembly 4 passes through, electromotor will be dynamic
Power passes to the second belt wheel 2 and the first belt wheel 1, while the first belt wheel 1 drives compressor of air conditioner, again
Drive the motor of the above-mentioned type so that motor is accumulator charging as electromotor, when by the above-mentioned type
When motor is as power source, accumulator constantly can provide electric energy for the motor as motor again.
Above example is only exemplary embodiment of the present utility model, is not used in restriction this utility model,
Protection domain of the present utility model is defined by the claims.Those skilled in the art can be new in this practicality
