[0006] As a preferred embodiment, the air pump body is configured as an air compressor.
[0007] As a preferred embodiment, the spline shaft is set to a standard 10-tooth spline shaft.
[0008] As a preferred implementation, the adapter plate is sleeved outside the air pump body, and the back side of the adapter plate overlaps with the front side of the connecting plate.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] The utility model is provided with an adapter plate, a spline shaft, a second mounting hole, a first mounting hole, a through hole and an air pump body. The first mounting hole and the bolt cooperate with each other to connect the adapter plate to the air pump body, and the adapter plate is screwed into the threaded hole at the output port of the engine through two external bolts. At this time, the power of the engine PTU power output port can be transmitted to the air pump through the spline shaft. The air pump generates compressed air to provide an air power source for the brakes of engineering vehicles. The air pump has the advantages of compact structure and low maintenance cost, and solves the problem that there is no dedicated air pump for the engine PTU power output port in the industry.

[0016] The present invention will be further described below in conjunction with the embodiments.
[0017] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0018] See also Figure 1-4The utility model provides an engine-specific air pump, including an air pump body 1, a bolt 2, an adapter assembly 3 and a spline shaft 4. The air pump body 1 includes an air pump body 11, a connecting plate 12 and a through hole 13. The connecting plate 12 is welded outside the air pump body 11. The air pump body 11 is set as an air compressor. There are two through holes 13, and the two through holes 13 are both opened in the connecting plate 12. There are two bolts 2, and the two bolts 2 are inserted into the through holes 13. The adapter assembly 3 includes an adapter plate 31, two first mounting holes 32 and two second mounting holes 33. The two bolts 2 are threadedly connected in the first mounting holes 32. By setting the bolts 2 and the first mounting holes 32, the two first mounting holes 32 and the two bolts 2 cooperate with each other to connect the adapter plate 31 with the air pump body 1.
[0019] The spline shaft 4 is clamped in the input shaft of the air pump body 11. The spline shaft 4 is set as a standard 10-tooth spline shaft 4. By setting the spline shaft 4, because the spline shaft 4 is machined by a SAE standard 10-tooth spline shaft 4 and a matching shaft hole of the spline shaft 4, the spline shaft 4 can transmit the power of the output shaft of the engine to the air pump;
[0020] The adapter plate 31 is sleeved on the outside of the pump body 11, and the back of the adapter plate 31 overlaps with the front of the connecting plate 12. By setting the pump body 11, because the pump body 11 is set as a piston compressor, the rotating spline shaft 4 can drive the crankshaft in the pump body 11 to rotate.
[0021] The working principle and usage process of the utility model are as follows: when the air pump needs to be used, the adapter plate 31 is put on the outside of the air pump body 11, and the back side of the adapter plate 31 overlaps the front side of the connecting plate 12. First, the two bolts 2 are respectively inserted into the through holes 13, and the two bolts 2 are respectively rotated. The two bolts 2 are respectively screwed into the two first mounting holes 32 in the adapter plate 31, and then the two external bolts are inserted into the second mounting holes 33 and respectively screwed into the engine PTU power output port, and then the spline shaft 4 is inserted into the output shaft of the engine. The spline shaft 4 is responsible for transmitting the rotational power of the engine to the air pump. The air pump generates compressed air to provide an air power source for the brakes of the engineering vehicle.
[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
