Abstract
The utility model relates to an automobile air compressor with an electromagnetic clutch, which comprises a drive shaft. The drive shaft is provided with a belt pulley connected with an engine; the belt pulley is internally provided with an electromagnetic clutch; an electromagnetic core packed with an electromagnetic coil is arranged in the cavity body of the belt pulley and is connected with a flange to form a whole; the electromagnetic core and the flange are fixed on an air compressor; one end surface of a drive shaft hub is connected with a spring leaf and supports and is connected with a suction disc through the spring leaf; the drive shaft hub is connected with the belt pulley through a bearing arranged on the drive shaft hub; and the end surface of the belt pulley corresponding to the electromagnetic coil and the suction disc is provided with at least two arc-shaped permeable grooves. The automobile air compressor attracts and separates the suction disc through the electromagnetic device and controls the drive shaft hub to drive the air compressor to work as required, thereby solving the problem that the air compressor does idle work at the most of the time to improve the effective power of the engine.
Description
Technical field
The utility model relates to a kind of automotive air compressor, specifically a kind of air compressor of charged magnet clutch.
Background technique
The air compressor of Shi Yonging generally directly is connected with motor by gear train or belt in the market, figure one is existing air compressor structure schematic representation, belt pulley 2 is installed on the live axle 8 of air compressor 1, motor is by belt pulley 2 runnings of belt drives air compressor 1, and structure is very simple.The air compressor and the motor of this kind structure start simultaneously, work and stop.Driving performance according to vehicle can be known with the decomposition of operation cycle in conjunction with correlation test in " GB18352 light-duty vehicle pollutant emission limit and method of measurement ", operating mode such as vehicle deceleration, braking is no more than 20% of whole operating modes, vehicle quickens, at the uniform velocity, operating mode such as slide and do not need to brake.Because structural reason, air compressor is still turning round always under these operating modes, consumption of engine power.The gas holder of vehicle just can be full of at short notice, and the pressurized air that continue to produce is discharged into the atmosphere by pressure-limit valve, thus the air compressor most of the time all flogging a dead horse, wasted a large amount of energy.And engine speed is very high when vehicle is run at high speed on the good road of road conditions such as expressway, the running rotating speed of corresponding air compressor is also very high, run up for a long time and will greatly shorten the life-span of air compressor, cause the accident causing vehicle to brake in case air compressor breaks down.And air compressor generally is installed in a certain side of motor, and the vibrations that the piston crank mechanism to-and-fro motion causes when its work can reduce the travelling comfort of vehicle.
Summary of the invention
Technical problem to be solved in the utility model is: at the shortcoming that exists in the above prior art, propose a kind of air compressor of charged magnet clutch, can solve the problem that the air compressor most of the time flogs a dead horse, and can improve effective engine power.
The technological scheme that the utility model solves above technical problem is:
The air compressor of charged magnet clutch, comprise live axle, the belt pulley that links to each other with motor is installed on the live axle, be provided with magnetic clutch in the belt pulley, magnetic clutch comprises the electromagnetic core that coats electromagnetic coil, flange plate, drive axle hub, spring sheet and adhesive dish, be provided with the electromagnetic core that coats electromagnetic coil in the belt pulley cavity, electromagnetic core links to each other with flange plate and becomes an integral body, electromagnetic core and flange plate are fixed on the air compressor, be connected with spring sheet on one end face of drive axle hub, and by spring sheet supporting connection adhesive dish, drive axle hub links to each other with belt pulley by the bearing of establishing thereon, is provided with at least 2 saturating magnetic grooves of circular arc with the end face of electromagnetic coil and the corresponding belt pulley of adhesive dish.
Electromagnetic core and flange plate are by being bolted on the air compressor.Drive axle hub is fixed on the live axle by swivel nut, is connected to the woodruff key that drives air compressor work on the drive axle hub.
Belt pulley is the electromagnetic coil rotation of electromagnetic core periphery relatively, and whether electromagnetic coil has electricity can not contact between the two.Motor is by the belt pulley running of belt drives air compressor, belt pulley did not contact with the adhesive dish when electromagnetic coil of electromagnetic core periphery was switched on, belt pulley is by being supported on the bearing rotation on the drive axle hub, belt pulley the idle running just and live axle of air compressor does not rotate, so air compressor is not worked.The electromagnetic coil energising of just giving the electromagnetic core periphery when having only baroceptor on being positioned at air delivering pipeline to detect pressure to be lower than setting value, under the effect of electromagnetic field, adhesive dish and belt pulley adhesive, by friction drive spring sheet and drive axle hub between the two, drive axle hub is fixed on the live axle by swivel nut, drives air compressor work by woodruff key.
The utility model has the advantages that: the utility model carries out adhesive and separates the adhesive dish by calutron, the controlling and driving propeller boss drives air compressor and works as required, solved the problem that air compressor most of the time flogs a dead horse, improve effective engine power, year is saved about 5000 yuan of fuel costs, the travelling comfort and the Security that have improved vehicle simultaneously.And having kept the installation of former air compressor and driving mode constant, original support and fitting seat can be general.

Embodiment
Embodiment one
The structure of present embodiment as shown in Figure 2, Fig. 3 is the structural representation of magnetic clutch of the present utility model, the belt pulley 2 of mounting strap magnetic clutch on the live axle 8 of air compressor 1, be provided with the electromagnetic core 3 that coats electromagnetic coil in belt pulley 2 cavitys, electromagnetic core 3 and flange plate 11 as a whole synthetic parts, be fixed on the air compressor 1 by bolt 12, belt pulley 2 is the electromagnetic coil rotation of electromagnetic core 3 peripheries relatively, and whether electromagnetic coil has electricity can not contact between the two.Be connected with spring sheet 5 on one end face of drive axle hub 6, and connect adhesive dish 4 by spring sheet 5 supportings; Be provided with at least 2 saturating magnetic grooves of circular arc with the end face of electromagnetic coil and adhesive dish 4 corresponding belt pulleys 2.Motor is by belt pulley 2 runnings of belt drives air compressor 1, belt pulley 2 did not contact with adhesive dish 4 when the electromagnetic coil of electromagnetic core 3 peripheries was switched on, belt pulley 2 is by being supported on bearing 9 rotations on the drive axle hub 6, belt pulley 2 the idle running just and live axle 8 of air compressor 1 does not rotate, so air compressor is not worked.The electromagnetic coil energising of just giving electromagnetic core 3 peripheries when having only baroceptor on being positioned at air delivering pipeline to detect pressure to be lower than setting value, under the effect of electromagnetic field, adhesive dish 4 and belt pulley 2 adhesives, by friction drive spring sheet 5 and drive axle hub 6 between the two, drive axle hub 6 is fixed on the live axle 8 by swivel nut 7, drives air compressor work by woodruff key 10.
The utility model can also have other mode of execution, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
