The effective rapid and accurate separation and combining of the clutch can be ensured in the prescribed air pressure value, the abrasion is reduced, and the service life is raised.
Description
The utility model belongs to the braking technology field of motor vehicle, is specifically related to a kind of technological improvement of auto-controlled clutch of air compressor.
Chinese patent CN86210628, the disclosed technological scheme of CN88203851 specification, it is the robot control system(RCS) that two patented technologies is used for the motor vehicle air compressor, clutch device is at the air compressor crank power intake, and the automatic control reverser is contained on the pipeline between clutch and the gas receiver, and the two is installed respectively and causes drawbacks such as structure is numerous and diverse, huge.
In addition, the automatic control reverser during real work, can not be carried out effectively control because structural design is unreasonable in the transition point of air pressure.And the pellet shot from a slingshot in the valve body is under the effect of spring, and the plunger with activity is in the state of suppressing all the time, and long term wear is easy to make plunger surface to produce impression and burr, even plunger and the stuck phenomenon of valve body can occur, influences the normal operation of air compressor.
The utility model overcomes the deficiencies in the prior art part, and a kind of self-controlling on and off air compressor of ladder plunger solenoidoperated cluthes gas circuit of simple in structure, reliable operation is provided.
The utility model is to realize like this, the self-controlling on and off air compressor, comprise the bent axle Piston and rod assembly, cylinder cap assembly, cylinder body, crankcase assembly, filter assembly, the air compressor of the air delivering pipeline and the parts that are connected and fixed, the power intake of air compressor is equipped with clutch assembly, in the clutch assembly clutch that it is characterized in that linking with air compressor gas circuit control mechanism and air delivering pipeline is housed.
---the right part that the cylinder of air delivering pipeline is positioned at the ladder plunger communicates with the intake duct of compression air compressor, the radial line that is located at the vertical each other sealing pipeline on the valve body communicates with the groove and the bleeder port of ladder plunger, axially pipeline communicates with air chamber, and air chamber is positioned at the top of piston.
---the gas circuit control mechanism is contained between valve body and the interior cover, is made up of piston, ladder plunger, spring, adjustment nut etc., and piston and clutch link, and seal ring is housed between ladder plunger and the piston, and spring is contained in the ladder plunger and adjusts between the nut.
The external diameter of ladder plunger of the present utility model is made of large and small two different diameters, and minor diameter one end has groove and several bleeder ports that communicate with atmosphere, and an end of bleeder port communicates with groove.
The utility model adopts ladder plunger control mechanism to control the clutch of air compressor clutch, not only accelerated plunger movement and also can guarantee fully clutch in the regulation atmospheric pressure value effectively, rapidly, clutch exactly.
Gas circuit control mechanism of the present utility model also can be contained on the pipeline between gas receiver and the clutch and use, and is equipped with respectively to communicate with the air compressor air intake road and block up joint, elastic member, adjustment component and constitutes by being contained in ladder plunger in the valve body and two ends.Description of drawings:
Fig. 1 is the structure erection drawing that gas circuit control mechanism of the present utility model and clutch combine as a whole
Fig. 2 is the assembly structure figure that is contained in the gas circuit control mechanism on the pipeline between gas receiver and the clutch of the present utility model

With reference to the accompanying drawings embodiment is done further detailed description.
It is example that present embodiment is contained on the east wind EQ-140 automobile with the self-controlling on and off air compressor, during installation, at first should be the pressure loosening valve of installing on the former automobile of installing to former air compressor cylinder cap top from gas receiver, pressure regulator valve and air delivering pipeline all remove and each output, inlet are shut, and all the other mounting points still remain unchanged.
The utility model is by air compressor host, crank Piston and rod assembly, cylinder cap assembly, filter assembly, air delivering pipeline, clutch assembly, compositions such as gas circuit control mechanism, the right part that the cylinder 19 of air delivering pipeline is positioned at the ladder plunger communicates with gas receiver, the gas circuit control mechanism is contained between valve body 1 and the interior cover 2, be made up of piston 6, ladder plunger 7, spring 8, adjustment bolt 13, oil sealing 14, ring washer 15 etc., spring 8 is contained in ladder plunger 7 and adjusts between the bolt 13.
Clutch mechanism shown in Figure 1 is a jointing state, when the pressurized air of continuous rising entered in the cylinder 19 from gas pipeline, ladder plunger 7 moves right under pressure, and was tangent with the left margin of radial seal pipeline 20, at this moment, the elastic force of spring 8 equates with the active force of air pressure specified value; When air pressure continues to raise, plunger 7 continues to move right, open radial seal pipeline 20, air pressure enters air chamber 21 from radial seal pipeline 20 through axial seal pipeline 20, plunger 7 overcomes the elastic force of spring 8, at this moment acts on active force on the plunger 7 considerably beyond the elastic force of spring 8, and the plunger 7 pneumatic tube passage that moves to right is rapidly all opened, at this moment act on elastic force that pressure on the piston overcomes spring 9 and promote clutch 12 and separate with wearing piece 4, air compressor quits work.When air pressure drops to 588KPa-637KPa, the elastic force of spring 8 makes plunger 7 move to left the right to the left side of groove 22 and radial seal pipeline 20 along tangent, at this moment the elastic force of spring 8 equates with active force on acting on plunger 7, air pressure continues to descend, plunger 7 is to moving to left, open the passage that cylinder 21 leads to atmosphere, pressurized gas releases through sealing pipeline 20, bleeder port 23; At this moment, the elastic force of spring 8 is far longer than the active force in the cylinder 19, and plunger 7 moves to left rapidly and resets.Spring 9 promotes piston and moves to right rapidly under the effect of elastic force, and clutch 12 engages with wearing piece 4, and air compressor is resumed work.
Embodiment 2 is mounted in the gas circuit control mechanism on gas receiver and the clutch pipeline, and working procedure is identical with embodiment 1.
The utility model compared with prior art has simple in structure, reliable operation, and gas circuit is unimpeded, and non-resistance can be controlled rapid, the accurately work of air-compressor clutch effectively, is a kind of renewal product of motor vehicles air compressor machine.
