Description

Technical Field

[0001] This application belongs to the technical field of clutch components, specifically relating to a clutch housing. Background Technology

[0002] The clutch housing is a crucial component of an engine, widely used in motorcycles. Its primary functions include housing the clutch, preventing dust and impurities from entering the clutch interior, and providing some support for other clutch components such as the valve cover and camshaft cover. Furthermore, it functions as a sealant and noise reducer, preventing oil leaks, maintaining cleanliness and lubrication within the clutch, and minimizing noise generated during operation. Therefore, the clutch housing is indispensable for the proper functioning of the clutch, and its integrity is critical to the engine's performance and lifespan.

[0003] The clutch housing cover has a protruding structure to house the crankshaft inside the clutch. During motorcycle operation, if an accidental collision or friction occurs, this protruding structure is easily damaged because it extends beyond the clutch housing. Since the clutch housing cover in current technology is a one-piece structure, damage to the protruding structure requires replacing the entire cover, resulting in significant financial losses for the user. Furthermore, routine maintenance of the motorcycle engine necessitates disassembling the entire cover to inspect the internal components; even if only the crankshaft corresponding to the protruding structure needs to be inspected, the entire cover must be removed, causing inconvenience. Utility Model Content

[0004] This application provides a clutch housing to solve the technical problems of conventional clutch housings where the cover can only be replaced as a whole, resulting in poor economy and difficulty in repairing the internal components of the clutch housing.

[0005] The technical solution adopted in this application is as follows:

[0006] A clutch housing includes a housing and a cover that covers the housing. The cover includes a first cover and a second cover. The first cover has a boss-shaped structure and is arranged corresponding to the crankshaft inside the housing. The first cover has a plurality of first mounting holes, and the second cover has a plurality of second mounting holes. The first cover and the second cover are detachably connected by inserting a first fixing member into the first mounting hole and the second mounting hole in sequence.

[0007] The clutch housing described in this application also includes the following additional technical features:

[0008] The second cover also includes a fixing hole. The box is provided with a mating hole that aligns with the fixing hole. The second cover is detachably connected by inserting a second fixing member into the fixing hole and the mating hole in sequence.

[0009] A portion of the first mounting hole aligns with the fixed insertion hole, and the first cover, the second cover, and the box are detachably connected by sequentially inserting the first mounting hole, the fixed insertion hole, and the third fixing member that mates with the insertion hole.

[0010] The first cover includes an outward protrusion, the outward protrusion being hollow to form a first mounting hole that aligns with the fixed insertion hole.

[0011] The top of the first mounting hole, which is aligned with the second mounting hole, is lower than the upper surface of the first cover, so as to form an operating space between the top of the first mounting hole and the upper surface of the first cover for inserting or removing the first fastener.

[0012] The first cover includes a top wall and a side wall. The first cover has a plurality of reinforcing ribs on the side facing the interior of the box. The reinforcing ribs abut against the top wall and the side wall respectively.

[0013] The top wall has a reinforcing boss on the side facing the interior of the housing. Each reinforcing rib is connected to the reinforcing boss. The reinforcing boss is aligned with the crankshaft and forms a clearance through hole for avoiding the crankshaft.

[0014] The first cover has multiple pull plates arranged at intervals along its circumference.

[0015] Most of the second mounting holes are spaced apart circumferentially along the second cover.

[0016] The first mounting hole and the second mounting hole are provided with matching internal threads, and the first fastener is a bolt.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0018] 1. The clutch housing of this application includes a first cover and a second cover. The first cover has a boss-shaped structure to form a large internal accommodating space. Since the crankshaft inside the housing needs to extend outward, it needs to occupy a large space. The accommodating space inside the first cover is used to accommodate the crankshaft. Based on this, the first cover and the second cover are provided with a first mounting hole and a second mounting hole, and the first cover and the second cover are detachably connected by a first fixing member that passes through the first mounting hole and the second mounting hole in sequence. In this way, when the first cover is damaged alone due to factors such as collision or tipping of the motorcycle, the first cover can be removed and replaced without replacing the second cover, which is more economical. In addition, when inspecting the internal components of the housing, if only the first cover needs to be opened to inspect the target component, such as the crankshaft, then only the first cover needs to be disassembled for inspection, instead of disassembling the entire cover for inspection, which reduces the difficulty of inspection.

[0019] 2. As a preferred embodiment of this application, the second cover and the box are detachably connected through a fixing hole and a mating hole. On the one hand, this facilitates the removal of the first cover connected to the second cover for the inspection of the internal components of the box. On the other hand, when the second cover is damaged or the entire cover is damaged, the second cover can be removed for replacement or the entire first cover can be replaced, reducing the difficulty of replacing the cover.

[0020] 3. In a preferred embodiment of this application, the first mounting hole is partially aligned with the fixed insertion hole, and the first cover, the second cover, and the box are detachably connected by sequentially inserting the first mounting hole, the fixed insertion hole, and the third fixing member that matches the insertion hole. This allows the first cover to be connected separately to the second cover on one hand, and sequentially connected to the second cover and the box on the other hand, thereby improving the connection strength between the first cover, the second cover, and the box and providing a stable guarantee for the protection of the internal components of the box by the cover.

[0021] 4. As a preferred embodiment of this application, since the third fastener is inserted into the first mounting hole, the fixing hole, and the mating hole in sequence, the length of the third fastener is relatively long, requiring a large operating space to be inserted from the first mounting hole. By setting the first outward protrusion and making the outward protrusion hollow inside to form the first mounting hole that aligns with the fixing hole, the first mounting hole is located on the outer periphery of the first cover body, making it easier for the operator to manipulate the third fastener into the first mounting hole, thus reducing the assembly difficulty of the cover body.

[0022] 5. As a preferred embodiment of this application, since the first cover protrudes from the box body, it is more likely to deform due to factors such as collisions. By setting reinforcing ribs, the structural strength of the first cover body can be improved, and the impact resistance and deformation resistance of the first cover body can be improved.

[0023] 6. As a preferred embodiment of this application, by providing a reinforcing boss, the impact resistance and deformation resistance of the first cover can be further improved, and the avoidance through hole provided in the reinforcing boss provides an avoidance position for the crankshaft, thus optimizing the structural design of the cover.

In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application.

[0038] like Figures 1 to 4 As shown, a clutch housing includes a housing 3 and a cover that covers the housing 3. The cover includes a first cover 1 and a second cover 2. The first cover 1 has a boss-shaped structure and is arranged corresponding to the crankshaft. The first cover 1 is provided with a plurality of first mounting holes 11, and the second cover 2 is provided with a plurality of second mounting holes 21. The first cover 1 and the second cover 2 are detachably connected by first fixing members that are sequentially inserted into the first mounting holes 11 and the second mounting holes 21.

[0039] The clutch housing of this application includes a first cover 1 and a second cover 2. The first cover 1 has a boss-shaped structure to form a large internal accommodating space. Since the crankshaft inside the clutch housing needs to extend outward, it needs to occupy a large space. The accommodating space inside the first cover 1 is used to accommodate the crankshaft. Based on this, the first cover 1 and the second cover 2 are provided with a first mounting hole 11 and a second mounting hole 21 respectively. The first cover 1 and the second cover 2 are detachably connected by a first fixing member that passes through the first mounting hole 11 and the second mounting hole 21 in sequence. In this way, when the first cover 1 is damaged alone due to factors such as collision or tipping of the motorcycle, the first cover 1 can be removed and replaced without replacing the second cover 2, which is more economical. In addition, when inspecting the internal components of the clutch housing, if only the first cover 1 needs to be opened to inspect the target component, such as the crankshaft, then only the first cover 1 needs to be disassembled for inspection, instead of disassembling the entire cover for inspection, which reduces the difficulty of inspection.

[0040] As a preferred embodiment of this application, such as Figure 3 As shown, the second cover 2 also includes a fixing hole 22, and the box 3 is provided with a mating hole that aligns with the fixing hole 22. The second cover 2 is detachably connected by inserting the second fixing member into the fixing hole 22 and the mating hole in sequence.

[0041] The second cover 2 and the box 3 are detachably connected through the fixing hole 22 and the mating hole. On the one hand, it is convenient to remove the first cover 1 connected to the second cover 2 for inspection of the internal components of the box 3. On the other hand, when the second cover 2 is damaged or the entire cover is damaged, the second cover 2 can be removed for replacement or the first cover 1 can be replaced together, reducing the difficulty of replacing the cover.

[0042] As a preferred embodiment of this implementation, such as Figures 1 to 3 As shown, part of the first mounting hole 11 is aligned with the fixed insertion hole 22, and the first cover 1, the second cover 2 and the box 3 are detachably connected by sequentially inserting the first mounting hole 11, the fixed insertion hole 22 and the third fastener of the matching insertion hole.

[0043] The first mounting hole 11 is partially aligned with the fixed insertion hole 22. The first cover 1, the second cover 2, and the box 3 are detachably connected by sequentially inserting the first mounting hole 11, the fixed insertion hole 22, and the third fastener that matches the insertion hole. This allows the first cover 1 to be connected to the second cover 2 independently on one hand, and to the second cover 2 and the box 3 sequentially on the other hand, thereby improving the connection strength between the first cover 1, the second cover 2, and the box 3 and providing a stable guarantee for the protection of the internal components of the box 3 by the cover.

[0044] In this embodiment, most of the first mounting hole 11 is aligned with the second mounting hole 21, and a small portion of the first mounting hole 11 is aligned with the fixing hole 22.

[0045] As a preferred example in this embodiment, such as Figure 2 As shown, the first cover 1 includes an outward protrusion 12, the interior of which is hollow to form a first mounting hole 11 that aligns with the fixing insertion hole 22. Since the third fastener is inserted sequentially into the first mounting hole 11, the fixing insertion hole 22, and the mating insertion hole, the third fastener is relatively long and requires a large operating space to be inserted into the first mounting hole 11. By providing the first outward protrusion 12 and making it hollow to form the first mounting hole 11 that aligns with the fixing insertion hole 22, the first mounting hole 11 is located on the outer periphery of the first cover 1. This allows the operator to more easily manipulate the third fastener into the first mounting hole 11, reducing the assembly difficulty of the cover.

[0046] Specifically, the protrusion 12 is a boss with a certain thickness, and the first mounting hole 11 is vertically opened inside the protrusion 12.

[0047] As another preferred example under this embodiment, such as Figure 2 As shown, the top of the first mounting hole 11, which is aligned with the second mounting hole 21, is lower than the upper surface of the first cover 1, so as to form an operating space between the top of the first mounting hole 11 and the upper surface of the first cover 1 for inserting or removing the first fastener.

[0048] Since the first fastener needs to be inserted into the first mounting hole 11 and the second mounting hole 21 in sequence above the first mounting hole 11, the staggered arrangement between the top of the first mounting hole 11 and the upper surface of the first cover 1 provides operating space for the disassembly tool when the first fastener is removed, making it easy for the operator to remove the first fastener, thereby achieving the separation of the first cover 1 and the second cover 2.

[0049] As a preferred embodiment of this application, such as Figure 4 As shown, the first cover 1 includes a top wall 13 and a side wall 14. The first cover 1 has multiple reinforcing ribs 15 on the side facing the interior of the housing 3, and the reinforcing ribs 15 abut against the top wall 13 and the side wall 14 respectively. Since the first cover 1 protrudes outward from the clutch housing, it is more likely to deform due to collisions or other factors. By providing reinforcing ribs 15, the structural strength of the first cover 1 can be improved, enhancing its impact resistance and deformation prevention capabilities.

[0050] Preferably, such as Figure 4As shown, the top wall 13 has a reinforcing boss 16 on the side facing the interior of the housing 3. Each reinforcing rib 15 is connected to the reinforcing boss 16. The reinforcing boss 16 is aligned with the crankshaft and forms a clearance through hole 161 for avoiding the crankshaft. By setting the reinforcing boss 16, the impact resistance and deformation resistance of the first cover 1 can be further improved. The clearance through hole 161 in the reinforcing boss 16 provides a clearance position for the crankshaft, thus optimizing the structural design of the cover. Each reinforcing rib 15 is connected to the reinforcing boss 16, so that when the first cover 1 is subjected to an impact force, at least part of the impact force can be transferred to the reinforcing boss 16 through the reinforcing rib 15, thereby improving the deformation resistance of the first cover 1.

[0051] As a preferred embodiment of this application, such as Figure 2 As shown, the first cover 1 is provided with a plurality of spaced lifting plates 17 along its circumference. By providing the lifting plates 17, a lifting position is provided for the user when disassembling the first cover 1, making it convenient for the user to lift and disassemble the first cover 1 through the lifting plates 17.

[0052] As a preferred embodiment of this application, such as Figure 3 As shown, most of the second mounting holes 21 are spaced apart circumferentially along the second cover 2. Setting the second mounting holes 21 to be spaced apart circumferentially along the second cover 2 helps to improve the connection strength and stability between the second cover 2 and the housing 3.

[0053] In a preferred embodiment of this application, the first mounting hole 11 and the second mounting hole 21 are provided with matching internal threads, and the first fixing member is a bolt. This arrangement reduces the difficulty of forming the first mounting hole 11 and the second mounting hole 21, as well as the difficulty of fitting the first fixing member with the first mounting hole 11 and the second mounting hole 21 respectively, making it easier to install and separate the first cover 1 and the second cover 2.

[0055] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
