Abstract
The utility model discloses a working condition control device of an auto air compressor, which aims to convert the air compressor between two working conditions of working and stopping working and achieve the purposes of saving energy and increasing efficiency. The working condition control device comprises an air compressor housing (10), an air compressor main shaft (11) and a driving wheel (12) which is driven by an engine. The working condition control device is characterized in that the driving wheel (12) is installed and fixed on the air compressor main shaft (11) by a bearing (13); a sliding sleeve (20) is arranged on the air compressor main shaft (11) by a key (14), and a friction disk (21) is arranged on the sleeve (20); and an electromagnetic clutch device which acts on the sliding sleeve (20) is arranged on the air compressor housing (10).
Description
Technical field
The utility model relates to automobile air compressor, and particularly a kind of air compressor that makes is at the control gear of working, quitting work and changing between two kinds of operating modes.
Background technique
Automobile air compressor is to provide braking force to transmit the equipment of energy to Pneumatic braking system.In general, motor car engine its air compressor that turns round also will ceaselessly turn round, and to the gas receiver inflation of Pneumatic braking system, use during in order to car brakeing.
The main shaft of existing automobile air compressor is connected with engine crankshaft belt pulley through fan pulley by belt transmission, and behind the engine start, air compressor is just worked always.During automobile running, if frequently do not use automobile brake, because air compressor does not stop inflation, the air pressure of pressurized gas can surpass the qualification pressure of its pressure-limit valve in the gas receiver, and at this moment, the pressurized air that pressure-limit valve is delivered to gas receiver with air compressor is discharged gas receiver.At this moment, the energy of the motor of air compressor consumption just has been wasted.Truck all adopts Pneumatic braking system, and particularly fully loaded when long slope (or long period at the uniform velocity travel) on expressway, it is important that these energy dissipations more seem, because more urgent to the needs of energy during vehicle driving up.
The model utility content
Technical problem to be solved in the utility model provides a kind of automobile air compressor operating mode control gear, and this device can make air compressor working, quitting work and change between two kinds of operating modes, makes it reach the purpose of energy efficiency.
The technological scheme that its technical problem that solves the utility model adopts is: automobile air compressor operating mode control gear of the present utility model, comprise air compressor housing, air compressor main shaft and by engine-driven drive wheel, it is characterized in that: described drive wheel is fixed on the air compressor main shaft by Bearing Installation; By key throwout sleeve is installed on the air compressor main shaft, sleeve is provided with friction plate; The air compressor housing is provided with the electromagnetic clutch device that acts on throwout sleeve.
The beneficial effects of the utility model are, can make air compressor work, quit work and change between two kinds of operating modes, after the air pressure of pressurized gas can reach and limit force value in gas receiver, air compressor quit work, thereby saves the energy consumption of motor effectively; Simple in structure, switching motion is reliable, can improve the existing traveling gear (truck, engineering machinery etc.) of air-pressure brake that uses easily, makes it reach the purpose of energy efficiency.
Description of drawings
This specification comprises as next width of cloth accompanying drawing:
Fig. 1 is the structural representation of the utility model automobile air compressor operating mode control gear.
Component shown in the figure, toponym and pairing mark: air compressor housing 10, air compressor main shaft 11, drive wheel 12, bearing 13, key 14, throwout sleeve 20, friction plate 21, spring 22, electromagnetic coil 23.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, automobile air compressor operating mode control gear of the present utility model comprises air compressor housing 10, air compressor main shaft 11 and by engine-driven drive wheel 12.Described drive wheel 12 is fixed on the air compressor main shaft 11 by bearing 13.Air compressor main shaft 11 is by being equipped with throwout sleeve 20 on the key 14, sleeve 20 is provided with friction plate 21.Air compressor housing 10 is provided with the electromagnetic clutch device that acts on throwout sleeve 20.Drive wheel 12 can adopt belt pulley or gear.Fig. 1 has shown the simplest electromagnetic clutch device of a kind of structure simultaneously, described electromagnetic clutch device is made of spring 22 and electromagnetic coil 23, electromagnetic coil 23 is fixedly mounted on the air compressor housing 10, on the spring 22 cover air compressor main shafts 11, its two ends act on throwout sleeve 20, air compressor housing 10 respectively.
When the pressure of braking system gas receiver is lower than 0.4MPa (or a certain setting atmospheric pressure value), spring 22 axial action are in throwout sleeve 20, make it to drive wheel 12 1 end slippages, when the friction plate on the throwout sleeve 20 21 with after drive wheel 12 contacts, drive wheel 12 just drives 11 rotations of air compressor main shaft, and air compressor is to the gas receiver inflation of braking system.When compressed-air actuated pressure in the gas receiver surpasses 0.8MPa (or a certain setting atmospheric pressure value), electromagnetic coil 23 is connected power supply and is produced magnetic force, make throwout sleeve 20 overcome the elastic force of spring 22 to returning slippage, drive wheel 12 and drive wheel 12 are disengaged, after this drive wheel 12 rotates and air compressor main shaft 11 does not rotate, and air compressor stops the gas receiver inflation to braking system.Therefore, the utility model can make air compressor work, quit work and change between two kinds of operating modes, and after the air pressure of pressurized gas can reach and limit force value in gas receiver, air compressor quit work, thereby saves the energy consumption of motor effectively.In addition, also have simple in structure, switching motion reliable, can carry out improved characteristics to the existing traveling gear (truck, engineering machinery etc.) of air-pressure brake that uses easily.
Some principles of the above the utility model automobile air compressor operating mode control gear that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the Applicable scope, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
