Description

Technical Field

[0001] This application relates to the field of transmission splines, and more specifically, to a transmission spline conversion sleeve for an air compressor. Background Technology

[0002] Air compressors are crucial components of automotive systems. They drive brake and clutch calipers to control braking; compressed air also functions as a water spray function in water brakes to cool the brake drums; and the air compressor is the heart of the automotive air conditioning system, enabling the refrigerant to change from a gaseous to a liquid state, thus facilitating refrigerant cooling and condensation. Hydraulic pumps are the power components of hydraulic systems, driven by an engine or electric motor. They draw hydraulic fluid from a tank, pressurize it, and deliver it to the actuators. Their working principle involves changes in the pump chamber volume caused by motion, compressing the fluid and giving it pressure energy. Hydraulic pumps are classified by structure into gear pumps, piston pumps, vane pumps, and screw pumps, among others.

[0003] Air compressors and hydraulic pumps are important component systems in various vehicles such as automobiles, engineering vehicles, and agricultural vehicles, and have a wide range of applications. Their design layouts are also diverse. However, traditional air compressor and hydraulic pump transmission splines require specially designed matching splines. Dedicated splines undoubtedly have poor versatility and great limitations. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides an air compressor drive spline conversion sleeve, which can solve the problem that traditional air compressor and hydraulic pump drive splines need to be specially designed, and that a single type of spline has poor versatility and great limitations.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An air compressor drive spline conversion sleeve includes an air compressor assembly and a drive assembly.

[0007] The air compressor assembly includes an engine block and an air compressor body, with the air compressor body located on one side of the engine block.

[0008] The transmission assembly includes a hydraulic pump body, a connecting plate, a transmission spline, and a spline conversion sleeve. The connecting plate is disposed at one end of the hydraulic pump body, the transmission spline is fixedly connected to the end of the hydraulic pump body, the spline conversion sleeve is installed at the end of the rotating shaft of the air compressor body, the connecting plate is fixedly connected to one side of the air compressor body, and the spline conversion sleeve includes a first spline sleeve and a second spline sleeve.

[0009] In one specific implementation, a gear chamber is provided on one side of the engine block, and the air compressor body is mounted on one side of the gear chamber.

[0010] In the above implementation process, by setting up a gear chamber, the traditional engine cylinder crankshaft drives the transmission gear in the gear chamber to rotate, thereby driving the air compressor body to operate.

[0011] In one specific implementation, the air compressor body has a mounting surface on one side, and the mounting surface has a threaded hole.

[0012] In the above implementation process, a mounting surface is provided with threaded holes for mounting and fixing with bolts to cooperate with the connecting plate.

[0013] In one specific implementation, a flange is provided on the other side of the air compressor body, and the flange is arranged correspondingly to the gear chamber.

[0014] In the above implementation process, a flange adapted to the gear chamber is used to stably install and connect the air compressor body to the gear chamber.

[0015] In one specific implementation, the first spline tube is an eleven-tooth spline tube, and the second spline tube is a nine-tooth spline tube.

[0016] In the above implementation process, by setting an eleven-tooth splined first splined and a nine-tooth splined second splined, it can be applied to a hydraulic pump body equipped with an eleven-tooth splined transmission spline or a nine-tooth splined transmission spline. The first and second splineds can be interchanged and adapted to the transmission splines of different hydraulic pump bodies, thereby adapting and assembling two transmission splines with different numbers of teeth and hydraulic pump bodies.

[0017] In one specific implementation, a rectangular hole is provided between the first splined cylinder and the second splined cylinder, and the rectangular hole is adapted to the end of the rotating shaft of the air compressor body.

[0018] In the above implementation process, by setting a rectangular hole, the spline conversion sleeve can fit snugly onto the rotating shaft of the air compressor body, ensuring stable and synchronous rotation during transmission.

[0019] In one specific implementation, a convex ring is provided on the outer side of the spline conversion sleeve, and the convex ring is located on the outer side of the first spline cylinder and the second spline cylinder.

[0020] In the above implementation process, by setting a convex ring, not only is the structural strength improved, but it also facilitates fixed connection during installation.

[0021] In one specific implementation, the spline conversion sleeve and the convex ring are integrally molded.

[0022] In the above implementation process, the unibody design structure has high strength and is more durable.

[0023] The advantages of this application embodiment are: by setting up an engine block, an air compressor body, a hydraulic pump body, a connecting plate, a transmission spline, and a spline conversion sleeve, the transmission spline and spline conversion sleeve can be used to make a transmission connection between the air compressor body and the hydraulic pump body. At the same time, the spline conversion sleeve includes a first spline sleeve and a second spline sleeve, which can adapt to the transmission splines on two types of hydraulic pump bodies, reduce the design and matching changes of the hydraulic pump, reduce the change design of the engine to set a special interface for the hydraulic pump, and improve the generalization design of important automotive component systems.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments.

[0030] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0031] In the embodiments, unless otherwise specified, all methods used are conventional methods in the art.

[0032] Please see Figures 1-4This application provides an air compressor drive spline conversion sleeve, which includes an air compressor assembly 100 and a transmission assembly 200.

[0033] Please see Figure 1 and 2 The air compressor assembly 100 includes an engine block 110 and an air compressor body 130, with the air compressor body 130 located on one side of the engine block 110.

[0034] The engine block 110 has a gear chamber 120 on one side, and the air compressor body 130 is installed on one side of the gear chamber 120. By setting the gear chamber 120, the traditional crankshaft of the engine block 110 drives the transmission gear in the gear chamber 120 to rotate, thereby driving the air compressor body 130 to operate.

[0035] Please see Figure 1 , 2 3 and 4, the transmission assembly 200 includes a hydraulic pump body 210, a connecting plate 220, a transmission spline 240 and a spline conversion sleeve 260. The connecting plate 220 is disposed at one end of the hydraulic pump body 210, the transmission spline 240 is fixedly connected to the end of the hydraulic pump body 210, the spline conversion sleeve 260 is installed at the end of the rotating shaft of the air compressor body 130, the connecting plate 220 is fixedly connected to one side of the air compressor body 130, and the spline conversion sleeve 260 includes a first spline cylinder 261 and a second spline cylinder 262.

[0036] The air compressor body 130 has a mounting surface 131 on one side, and the mounting surface 131 has a threaded hole. The mounting surface 131 and the threaded hole are used to cooperate with the connecting plate 220 for installation and fixation with bolts.

[0037] Specifically, a flange 132 adapted to the gear chamber 120 is provided for the stable installation and connection of the air compressor body 130 to the gear chamber 120.

[0038] In this embodiment, the first spline tube 261 is an eleven-tooth spline tube, and the second spline tube 262 is a nine-tooth spline tube.

[0039] It should be noted that a rectangular hole 263 is provided between the first splined sleeve 261 and the second splined sleeve 262. The rectangular hole 263 is adapted to the end of the rotating shaft of the air compressor body 130. By providing the rectangular hole 263, when the splined conversion sleeve 260 is adapted to the rotating shaft of the air compressor body 130, it can fit snugly and ensure stable synchronous rotation during transmission.

[0040] In one specific implementation, a protruding ring 270 is provided on the outer side of the spline conversion sleeve 260. The protruding ring 270 is located on the outer side of the first spline cylinder 261 and the second spline cylinder 262. By providing the protruding ring 270, not only is the structural strength improved, but it also facilitates the fixed connection during installation.

[0041] In one specific implementation, the spline conversion sleeve 260 and the convex ring 270 are integrally molded. In the above implementation process, the integrally molded design has high structural strength and is more durable.

[0042] The working principle of the air compressor transmission spline conversion sleeve is as follows: When assembling the hydraulic pump body 210, the spline conversion sleeve 260 is fitted onto the rotating shaft of the air compressor body 130. The rectangular hole 263 of the spline conversion sleeve 260 is used to fit onto the rotating shaft of the air compressor body 130 for fixing. Then, the hydraulic pump body 210 is installed, and the connecting plate 220 and the mounting surface 131 are aligned. Bolts are then passed through the threaded holes of the connecting plate 220 and screwed into the threaded holes. At the same time, the transmission spline 240 is aligned and inserted into the spline conversion sleeve 260 for connection. Furthermore, when installing the spline conversion sleeve 260, the first spline sleeve 261 or the second spline sleeve 262 is selected to face outward according to the number of teeth of the transmission spline 240 on the hydraulic pump body 210, ensuring that the transmission spline 240 can be adapted. It can adapt to the transmission spline 240 on two types of hydraulic pump bodies 210, reducing the design and matching changes of the hydraulic pump, reducing the need for the engine to set up a special interface for the hydraulic pump, and improving the generalization design of important automotive component systems.

[0043] It should be noted that the specific model and specifications of the air compressor body 130 and the hydraulic pump body 210 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0044] The power supply and operating principle of the air compressor body 130 and the hydraulic pump body 210 are clear to those skilled in the art and will not be described in detail here.

[0045] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
