Abstract

The utility model relates to a car air-condition clutch of balance weight, which is used wholly on the car air condition and comprises a transmission wheel, a electromagnetic loop and a gag bit (a driving plate assembly). The utility model is characterized in that a hub 5 of the gag bit is provided with a balance weight keyboard 9 and moves frontward along the axial direction of the keyboard 9, the keyboard 9, a driving board 6 and a reed 7 are connected into one unit by a rivet 3. Finally the whole gravity center of a driving plate moves frontward (from 3 to 4 mm) and the axial distance between the clutch and the compressor is shortened, the axial bending moment of the sport is reduced. Moreover because the separated balance weight makes the driving plate principally balanceable axially, the shake is reduced largely when the utility model works and the system noise of the compressor is debased more than 4 decibels; therefore the long-term problem of shake and super-standard noise is solved.

Description

Balance weight formula automobile air conditioner electromagnetic clutch
Technical field:
The utility model relates to the magnetic clutch that is exclusively used in air conditioning for automobiles.
Background technology:
Now the automobile air conditioner electromagnetic clutch that uses has three parts and forms: i.e. power wheel, magnet coil, driving disk assembly (armature).Power wheel on the compressor protecgulum, drives running by driving engine by bearing installation, and the coil rear end is fixed on the compressor protecgulum, and front end places in the corresponding iron core slot of power wheel, and driving disk is connected on the compressor main shaft by binding.Coil electricity during work, the driving disk adhesive, belt pulley drives the driving disk running, and driving disk drives the compressor main shaft running by key.And single syncline disc type compressor with variable displacement particularly, because its constructional feature, internal motion spare produces a unbalanced moment, is the normal operation that guarantees compressor, the reverse counterweight of general using power-transfer clutch keeps balance.Conventional clutch realizes by adding a Weight plate on the driving disk.This counterweight mode has been brought new problem simultaneously in the balance that keeps total system, power-transfer clutch itself is in axially and the non-equilibrium state of both direction radially, the noise that compressor and power-transfer clutch vibrations etc. produce during high-speed operation is bigger, along with the raising of auto-industry to the noise strength standard requirement, system noise can not be up to standard during the running of original design power-transfer clutch, and bigger for satisfying counterweight needs Weight plate area, manufacturability is relatively poor.Extensively retrieve at the problems referred to above, do not find relevant technical scheme as yet.
Summary of the invention:
The purpose of this utility model is exactly a kind of later-model automobile air conditioner electromagnetic clutch of shortcoming design-calculated that the Weight plate area is big, noise is big, manufacturability is relatively poor that exists in the prior art for solving.
To achieve these goals, the utility model has adopted following technical scheme: balance weight formula automobile air conditioner electromagnetic clutch, it is made up of power wheel, magnet coil and armature (driving disk assembly), magnet coil is fixed in the iron core slot of power wheel, armature matches with magnet coil and power wheel, it is characterized in that on the wheel hub of armature a counterweight keyboard being set and along wheel hub axial advancement certain distance, described counterweight keyboard and drive plate and reed combine as a whole with rivet.The essence of this programme is that former drive plate counterweight is decomposed, be divided into keyboard counterweight and drive plate counterweight, the flange face of keyboard is made weight off-centre, former drive plate counterweight reduces weight, by the combined riveting of reed, pad etc., makes the reach of counterweight keyboard near the sucker attrition surface, finally make the whole center of gravity reach of driving disk (about 3-4 mm), shortened the axial distance with compressor, the axial moment of flexure when having reduced motion, and since separately counterweight make driving disk be in the longitudinal balance state basically.
Owing to adopted technique scheme, vibrations greatly reduce when making the utility model work, more than the compressor assembly noise decline 4-5 decibel, have solved the problem that noise for a long time exceeds standard; Drive plate of the present utility model in addition adopts riveted joint to connect with wheel hub and keyboard, and than the welded structure good manufacturability of original employing, cost also decreases.
In order to describe the utility model in detail, following accompanying drawing provides a most preferred embodiment of the present utility model.
Description of drawings:
Fig. 1 is a front view of the present utility model;
Fig. 2 is the E-E cutaway view of Fig. 1.
The specific embodiment:
As shown in Figure 1 be the front view of armature of the present utility model (driving disk assembly), it mainly is made up of sucker 1, wheel hub 5, three reeds 7, drive plates 6, drive plate 6 is provided with three noise reduction plugs 2, the outer rivet 8 of each reed 7 usefulness is riveted on the sucker 1; The position of reed 7 and inside and outside rivet 3,8 is symmetrically arranged with the sucker center, wheel hub 5 is provided with counterweight keyboard 9, the flange face of drive plate 6, counterweight keyboard 9 is (below drive plate, as shown in phantom in FIG.) be asymmetric small one and large one sector structure, purpose is in order to give the compressor assembly balance weight.As shown in Figure 2, interior rivet 3 riveted joints of drive plate 6, reed 7, pad 4 and counterweight keyboard 9 usefulness connect, counterweight keyboard 9 moves down 3-5mm along the axial Z of wheel hub 5, be arranged in the sucker circular hole, can reduce the counterweight amount and the area of drive plate 6 like this, make the whole down-shift of working center 3-4mm of sucker, promptly shortened the axial distance of power-transfer clutch and compressor, moment of flexure when having reduced the compressor main shaft motion, under the state of compressor high-speed motion, the small reach of power-transfer clutch center of gravity makes reducing of compressor moment of flexure, to reducing to shake and The noise all is huge.
