Abstract
The present invention provides a kind of driving disc assembly of overload protective device; it includes flower keyboard (1); driving plate (2) are arranged in flower keyboard (1) side; reed (3) are equipped in driving plate (2) side; one group of elastic slice (3a) is evenly equipped on reed (3), between one end end insertion driving plate (2) of the elastic slice (3a) and flower keyboard (1).It is the configuration of the present invention is simple, easily manufactured, low in cost, after driver torque is more than setting value, by the disengaging of elastic slice and driving plate and flower keyboard, so that compressor stops working, to play the role of overload protection.
Description
Technical field:
The present invention relates to the drivers for air conditioning for automobiles, are specifically exactly a kind of driving disc assembly of overload protective device.
Background technique:
Air conditioning for automobiles driver, it is ensured that when compressor reaches quota torque value, compressor stops working, and dress can be effectively protected
The service life set.But the structure of existing air-conditioning torque limiter, most structure is complex, this makes air-conditioning driver
Manufacturing cost increases, and the maintenance after protective device damage is also more inconvenient.Although also occurring in existing technology some
Driver with overload protection, but be all mostly that overload protection, but reed are realized by the way of reed in discommect drive
The fragment to splash when disconnection usually damages other components, and the also extremely difficult thorough removing of then tiny fragment causes vehicle to run
The problems such as Shi Fangsheng abnormal sound.
Summary of the invention:
The present invention is exactly in order to overcome the shortcomings in the prior art, to provide a kind of driving disc assembly of overload protective device.
The present invention the following technical schemes are provided:
A kind of driving disc assembly of overload protective device, it includes flower keyboard, it is characterised in that: be evenly equipped on flower keyboard one group to
First extension of outer stretching is arranged with driving plate in flower keyboard side, and one group outwardly directed is evenly equipped in driving plate
Two extensions are equipped with a pair of of card slot on each second extension, the reed of annular are arranged in driving plate side, in annular
One group of arc spring lamination is evenly equipped on reed, one end end of the arc spring lamination is equipped with a pair of fixture block with card slot corresponding matching.
Based on the above technical solution, there can also be technical solution further below:
The first bending line and the second bending line are equipped on each arc spring lamination, the first bending line length direction
Extended line passes through the reed center of circle, second bending line and the first bending line parallelly distribute on, and the second bending line and reed are radial
Between be equipped with angle.
Width is all the same everywhere in the piece body of the arc spring lamination.
Invention advantage:
The configuration of the present invention is simple, easily manufactured, low in cost, compact overall structure, receiving torque value is big, when driver torque is super
After crossing setting value, by the disengaging of elastic slice and pin, so that compressor stops working, to play the role of overload protection.
Detailed description of the invention:
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the schematic perspective view of Fig. 1；
Fig. 3 is the structural schematic diagram of reed in Fig. 1.
Specific embodiment:
As shown in Figure 1-3, a kind of driving disc assembly of overload protective device, it includes flower keyboard 1, is evenly equipped with one on flower keyboard 1
The outwardly directed first extension 1a of group, is arranged with driving plate 2 in 1 side of flower keyboard, be evenly equipped in driving plate 2 one group it is outside
The the second extension 2a stretched out is equipped with the card slot 2b of a pair of symmetrical arc on each second extension 2a.
It is arranged with the reed 3 of annular in 2 side of driving plate, three pieces arc spring lamination 3a is evenly equipped on the outside of reed 3, it is described
The first bending line a and the second bending line b, the first bending line a length direction are equipped with the piece of every arc spring lamination 3a
Extended line pass through the center of circle of reed 3, the second bending line b and the first bending line a parallelly distribute on, and the second bending line b
Extended line is equipped with angle c between 3 radial direction of second bending line b and reed without the center of circle of reed 3.
It is equipped with the plug division of horizontal distribution in the end of the every side arc spring lamination 3a the first bending line a, on plug division
Equipped with a pair of fixture block 3b with card slot 2b corresponding matching, it is equipped with the interconnecting piece connecting with reed 3 in the other end of arc spring lamination 3a,
The mounting hole 3c that cooperation is connect with belt wheel not shown in figure is equipped on interconnecting piece, the interconnecting piece is also horizontal distribution, but
With plug division not in same level, the interconnecting piece and reed 3 are higher than the water where plug division in same level
Plane.
The center of circle of fixture block 3b on the plug division every arc spring lamination 3a is distributed on same circumference.Due to arc bullet
Interconnecting piece and plug division of the on piece equipped with the first bending line a and the second bending line b and arc spring lamination 3a be not in same level
On, so that reed is provided with certain elasticity radially.Width is homogeneous everywhere for the piece body of the arc spring lamination 3a length direction
Together.
The plug division of arc spring lamination 3a is inserted between the first extension 1a and the second extension 2a, and fixture block 3b is caught in
In corresponding card slot 2b, then driving plate 2 is fixedly connected on flower keyboard by rivet 4.
The center gasket of not shown compressor main shaft corresponding matching in figure is additionally provided in the splined sleeve 5 of flower keyboard 1
5a。
The course of work:
Belt wheel passs power to reed, and then reed passes through arc spring lamination for the power place of production to driving plate, and driving plate then passes through riveting
For nail by power special delivery to flower keyboard, last flower keyboard imparts power to compressor.When the torque of belt wheel input is more than specified value
Afterwards, the fixture block on arc spring lamination plug division will be detached from from the card slot on the second extension of driving plate.Due to the every arc
Shape elastic slice is connected with reed, and the center of circle of the fixture block on plug division is distributed on same circumference, thus ensuring that all cards
Block is synchronous with card slot to be detached from.It is disconnected so that the power of belt wheel conducts, plays the role of overload protection to compressor.
