Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Art

[0002] Air conditioning, as a configuration to improve the comfort in the cockpit, has gradually become one of the indispensable functions of some all-terrain vehicles.

[0003] The air conditioning system's refrigeration components mainly include: compressor, condenser, expansion valve and evaporator. After receiving the refrigeration command, the compressor's clutch engages, thereby driving the compressor's internal structure to work. During vehicle driving, the tires will throw up sand, mud and other foreign objects. When foreign objects enter between the clutch and the main body of the compressor, the clutch engagement will easily cause wear and even damage between the compressor and the clutch.

[0004] In the existing air conditioner electromagnetic clutch, a dust cover is fixedly mounted on the transmission wheel and wraps the clutch. The existence of the dust cover protects the clutch, but there are the following defects:

[0005] The fixing screws of the dust cover are located on the circumferential surface of the transmission wheel. During the rotation of the transmission wheel, the screws will have a radial outward centrifugal force. At this time, the dust cover is at risk of loosening or even falling off, and the protection of the clutch is unreliable. Summary of the invention

[0006] In order to address the deficiencies of the prior art, the purpose of the present application is to provide an all-terrain vehicle that reduces the probability of loosening or even falling off of the protective cover.

[0007] To achieve the above-mentioned purpose, the present application adopts the following technical solutions: an all-terrain vehicle, the all-terrain vehicle comprises a frame, a transmission assembly, a power system and a compressor assembly, the transmission assembly is at least partially supported by the frame, the power system is at least partially arranged on the frame, and the power system is transmission-connected to the transmission assembly; the compressor assembly comprises a compressor, a clutch, a protective cover and a transmission wheel, the compressor comprises a body and a main shaft arranged on the body, the transmission wheel is mounted on the main shaft, and the transmission assembly is transmission-connected to the transmission wheel to drive the transmission wheel to rotate around the axis of the main shaft; the protective cover is arranged on the side of the transmission wheel away from the body, and the protective cover and the transmission wheel are enclosed to form a receiving cavity; the clutch is mounted on the main shaft and is located in the receiving cavity; at least two limiting grooves extending along the axial direction of the main shaft are opened on the transmission wheel, and each of the limiting grooves is arranged at intervals along the circumference of the transmission wheel on the periphery of the receiving cavity, and the compressor assembly also includes a connecting piece corresponding to the limiting groove, and the connecting piece is mounted on the protective cover and can be at least partially constrained in the limiting groove.

[0008] Furthermore, the transmission wheel has a flange on the end surface facing the protective cover, the flange extends along the circumference of the transmission wheel and is located at the periphery of the clutch, and the limiting groove is located on the flange. In addition, the flange can also be provided on the protective cover, but from the perspective of reliability, it is preferred to form the above-mentioned flange on the transmission wheel.

[0009] The connecting member and the protective cover can be detachably connected or fixedly connected, such as by forming a buckle on the protective cover. However, from the perspective of installation reliability, the preferred solution is that the connecting member is a screw or bolt with a screw rod, and the protective cover is provided with a mounting hole for the screw rod to pass through at a position corresponding to the limiting groove, and the limiting groove is a screw hole that cooperates with the screw thread.

[0010] Furthermore, the protective cover includes a cover body and an extension plate extending radially outward from the outer periphery of the cover body, and the mounting hole is located on the extension plate. The existence of the extension plate and the location of the mounting holes on the same mounting surface ensure the reliability of the connection between the protective cover and the transmission wheel, and avoid the protective cover from falling off during the rotation of the transmission wheel.

[0011] Furthermore, the flange is provided with a groove in which at least a portion of the extension plate is located, the groove extends along the circumference of the flange, and the limiting groove is located in the groove.

[0012] During the rotation of the transmission wheel, the presence of the groove further limits the radial outward movement of the protective cover along the transmission wheel, which is beneficial to improving the firmness of the installation of the protective cover and providing more reliable protection for the clutch.

[0013] There are many structural forms of the transmission assembly, which can be a driving wheel and belt, a driving wheel and chain, or a driving wheel and other gear transmission. The preferred forms are as follows:

[0014] The transmission assembly includes a driving wheel and a belt for transmitting power to the transmission wheel. The power system is transmission-connected to the driving wheel. The transmission wheel is a pulley. The belt surrounds the driving wheel and the pulley.

[0015] To facilitate the overall installation of the compressor assembly, the power system includes an engine and a bracket, the engine has a shell, and the bracket is installed on one of the left and right side walls of the shell along the width direction of the frame, and the compressor assembly is installed on the bracket.

[0016] In order to prevent foreign objects from contacting the belt and damaging the belt, the power system also includes a protective cover, and the side wall of the outer shell on which the bracket is installed is defined as a side panel, and the protective cover is installed on the side panel. The protective cover, the bracket and the side panel together enclose a accommodating cavity, and the compressor assembly and the transmission assembly are both located in the accommodating cavity.

[0017] Furthermore, the all-terrain vehicle also includes an exhaust pipe, which is at least partially disposed on the frame, and the protective cover is located below the exhaust pipe.

[0018] The arrangement of the exhaust pipe and the protective cover enables the protective cover to separate the exhaust pipe from the compressor, which can play a certain heat insulation role and also improve the cooling effect of the air conditioner to a certain extent.

[0019] In order to facilitate the disassembly and assembly of the air-conditioning pipeline, the compressor assembly also includes a pipeline connected to the compressor, and the protective cover is provided with an escape opening for the pipeline to pass through at a position corresponding to the pipeline.

[0020] In the above-mentioned all-terrain vehicle, the connecting piece arranged on the protective cover can be at least partially constrained in the limiting groove of the transmission wheel. In this way, the connection between the protective cover and the transmission wheel can be achieved through the connecting piece. The protective cover and the transmission wheel wrap the clutch. During the rotation of the transmission wheel, even if there is centrifugal force, since the limiting groove extends along the axial direction of the main shaft, the radial outward movement of the protective cover is avoided. The protective cover is more reliably connected to the transmission wheel, and the clutch will be more reliably protected, avoiding the situation where foreign objects contact the clutch due to loosening or even falling off of the protective cover, thereby extending the service life of the clutch.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0032] like Figure 1 As shown, the length direction of the all-terrain vehicle 100 is taken as the front-to-back direction, the width direction of the all-terrain vehicle 100 is taken as the left-right direction, and the height direction of the all-terrain vehicle 100 is taken as the up-down direction. Figure 1 Front, back, left, right, top, and bottom are defined.

[0033] Depend on Figure 1 Combination Figure 3 and Figure 5 It can be seen that the all-terrain vehicle 100 includes a frame 11, a power system 12, a transmission assembly 13, a compressor assembly 14, an exhaust assembly 15, a travel assembly 17 and a suspension assembly 18. Figure 2 As shown, the frame 11 includes a front frame 111, a middle frame 112 and a rear frame 113 which are sequentially arranged along the length direction of the frame 11. The front frame 111, the middle frame 112 and the rear frame 113 are sequentially connected from front to back.

[0034] Depend on Figure 1 Combination Figure 2It can be seen that the travel assembly 17 is arranged on the frame 11 through the suspension assembly 18, the suspension assembly 18 includes a front suspension 181 and a rear suspension 182, the travel assembly 17 includes a front wheel 171 and a rear wheel 172, the front wheel 171 is installed on the front frame 111 through the front suspension 181, and the rear wheel 172 is installed on the rear frame 113 through the rear suspension 182. The power output end of the power system 12 is drivingly connected to the front wheel 171 and / or the rear wheel 172, that is, the power system 12 is drivingly connected to the front wheel 171 and / or the rear wheel 172, so as to realize the travel of the all-terrain vehicle 100.

[0035] like Figure 2 , Figure 3 Combination Figure 5 As shown, the power system 12 is at least partially disposed on the vehicle frame 11. The power input end of the transmission assembly 13 is transmission-connected to the power output end of the power system 12, that is, the power system 12 is transmission-connected to the transmission assembly 13. In this embodiment, the power system 12, the compressor assembly 14 and the exhaust assembly 15 are at least partially disposed on the rear frame 113.

[0036] like Figure 6 , Figure 7 Combination Fig. 9 As shown, the compressor assembly 14 includes a compressor 141, a clutch 142, a protective cover 143, a transmission wheel 144 and a pipeline 145. Figure 8 and Fig. 9 As shown, the compressor 141 includes a body 1411 and a main shaft 1412 disposed on the body 1411. The transmission wheel 144 is mounted on the main shaft 1412. Figure 5 As shown, the transmission wheel 144 is in transmission connection with the power output end of the transmission assembly 13, that is, the transmission assembly 13 is in transmission connection with the transmission wheel 144, so that the transmission wheel 144 can rotate around its own axis under the transmission of the transmission assembly 13. In this way, the power is transmitted to the transmission wheel 144 through the transmission assembly 13. In this embodiment, the transmission assembly 13 is at least partially supported by the frame 11, such as Figure 5 and Figure 7 As shown, the transmission assembly 13 includes a driving wheel 131 and a belt 132 for transmitting power to the transmission wheel 144. Figure 3 Combination Figure 5As shown, the power system 12 includes an engine 121, a protective cover 122 and a bracket 123. The driving wheel 131 is installed on the power output end of the engine 121, that is, the engine 121 is connected to the driving wheel 131. The aforementioned driving wheel 131 is located in front of the transmission wheel 144. The aforementioned transmission wheel 144 is a pulley, and the belt 132 surrounds the driving wheel 131 and the outer periphery of the pulley. In this way, when the engine is working, it drives the driving wheel 131 to rotate around its own axis, and the rotating driving wheel 131 drives the pulley to rotate around its own axis through the belt 132.

[0037] like Figure 5 As shown, the engine 121 has a housing 1211. Along the width direction of the vehicle frame 11, the bracket 123 is mounted on one of the left and right side walls of the housing 1211, and the compressor 141 is mounted on the bracket 123. The side wall of the housing 1211 on which the bracket 123 is mounted is defined as a side plate 1211a. In this embodiment, the side plate 1211a is on the right side wall of the housing 1211, and the compressor 141 is mounted on the right side of the bracket 123. Then, the compressor 141 is mounted on the right side wall of the housing 1211 through the bracket 123. In this embodiment, Figure 7 As shown, the front side of the bracket 123 has a guard plate 1231 extending to the right, and the compressor 141 is located behind the guard plate 1231.

[0038] In order to avoid direct impact of foreign objects such as branches and stones on the compressor 141, thereby protecting the safety of the compressor 141 and the transmission assembly 13, as shown in FIG. Figure 2 , Figure 3 and Figure 5 As shown, the protective cover 122 is mounted on the side plate 1211a of the housing 1211. The protective cover 122, the bracket 123 and the side plate 1211a together form the accommodating chamber 101. Figure 2 Combination Figure 3 and Figure 5 As shown, the compressor assembly 14 and the transmission assembly 13 are both located in the accommodating chamber 101. In this embodiment, the protective cover 122 is located on the right side of the engine 121. In addition, the right side of the above-mentioned pulley is close to the right rear suspension (not shown), and the right rear suspension is located on the right side of the protective cover 122. Then the protective cover 122 separates the pulley and the right rear suspension, further ensuring the safety of the belt 132 during operation.

[0039] In addition, if Figure 6 and Figure 7 As shown, the protective cover 122 and the bracket 123 are provided with connection holes 103 for connecting the mounting member. The connection hole 103 is arranged away from the guard plate 1231. The mounting member is a screw or a bolt. The screw or the bolt is installed on the connection hole 103 to realize the installation of the protective cover and the bracket 123.

[0040] like Figure 2 , Figure 4 Combination Figure 5 As shown, the exhaust assembly 15 includes an exhaust pipe 151, which is at least partially disposed on the vehicle frame 11, and the compressor assembly 14 is located below the exhaust pipe 151. During the driving of the all-terrain vehicle 100, the exhaust pipe 151 will have a relatively high temperature around it. In order to prevent the heat from being transferred to the compressor 141 and affecting the performance of the compressor 141, the protective cover 122 is located below the exhaust pipe 151. In this way, the protective cover 122 separates the exhaust pipe 151 from the compressor 141, which can play a certain role in heat insulation, and also improves the cooling effect of the air conditioner to a certain extent.

[0041] like Figure 6 As shown, the above-mentioned pipeline 145 is connected to the compressor 141, and the above-mentioned pipeline 145 is an air conditioning pipeline. Since the air conditioning pipeline needs to be connected to the compressor 141, there will be a need for maintenance and assembly. In order to facilitate maintenance and assembly, Figure 3 and Figure 6 As shown, the protective cover 122 is provided with an escape opening 1221 at a position corresponding to the pipeline 145 for the pipeline 145 to pass through.

[0042] When the all-terrain vehicle 100 is running in a harsh environment, small foreign objects such as sewage, mud, and dust brought up by the tires may enter between the clutch 142 and the compressor 141. In order to prevent foreign objects from entering between the clutch 142 and the compressor 141, Figure 8 and Fig. 9 As shown, the protective cover 143 is arranged on the side of the transmission wheel 144 away from the body 1411. The protective cover 143 and the transmission wheel 144 enclose a receiving chamber 102. The clutch 142 is mounted on the main shaft 1412, and the clutch 142 is located in the receiving chamber 102. When the compressor is in high-speed operation after the clutch 142 is engaged, the receiving chamber 102 enclosed by the protective cover 143 and the transmission wheel 144 wraps up the clutch 142, ensuring that the clutch 142 on the compressor 141 is in a dust-free environment, and is as unaffected by the outside world as possible during the engagement process, that is, it is prevented from foreign objects entering and causing wear or even damage to the clutch 142, thereby increasing the service life of the clutch 142.

[0043] In addition, the protective cover 143 can be closely attached to the transmission wheel 144, thereby protecting the clutch 142 while occupying as little additional space as possible.

[0044] In order to achieve reliable installation of the protective cover 143, as Figure 8 and Fig. 9As shown, the transmission wheel 144 has a circle of flange 1441 on the end surface facing the protective cover 143, and the flange 1441 extends along the circumference of the transmission wheel 144. The flange 1441 is located at the periphery of the clutch 142, and at least two limiting grooves 1441a are provided on the flange 1441, both extending along the axial direction of the main shaft 1412. The aforementioned limiting grooves 1441a are located on the transmission wheel 144. At least two limiting grooves 1441a are arranged at intervals along the circumference of the flange 1441. In this embodiment, there are three limiting grooves 1441a. In addition, more than three limiting grooves can also be used.

[0045] like Figure 8 and Fig. 9 As shown, the compressor assembly 14 further includes a connecting piece corresponding to the limiting groove 1441a, the connecting piece is mounted on the protective cover 143, and at least a portion of the connecting piece can be constrained in the limiting groove 1441a. In this embodiment, the protective cover 143 is provided with a mounting hole 1432a at a position corresponding to the limiting groove 1441a, through which only a portion of the connecting piece passes. The aforementioned connecting piece is a screw 147 or a bolt having a screw rod 1471, the limiting groove 1441a is a screw hole threadedly matched with the screw rod 1471, and the aforementioned mounting hole 1432a is only for the screw rod 1471 to pass through.

[0046] During the rotation of the transmission wheel 144, even if there is centrifugal force, since the limiting groove 1441a extends along the axial direction of the main shaft 1412, the radial outward movement of the protective cover 143 is avoided, and the protective cover 143 will be more reliably connected to the transmission wheel 144. The clutch 142 will be more reliably protected to avoid the situation where foreign objects contact the clutch due to loosening or even falling off of the protective cover 143, thereby extending the service life of the clutch 142.

[0047] In some embodiments, the protective cover 143 includes a cover body 1431 and an extension plate 1432 extending radially outward from the outer circumference of the cover body 1431, and the mounting holes 1432a are located on the extension plate 1432. Then, each mounting hole 1432a is located on the same extension plate 1432. In addition, the flange 1441 is provided with a groove 1441b in which at least a portion of the extension plate 1432 is located, and the groove 1441b extends along the circumference of the flange 1441. The above-mentioned limiting groove 1441a is located in the groove 1441b.

[0048] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to this application.
