Description

Technical Field

[0001] The utility model relates to the technical field of transmissions, in particular to a transmission clutch hub. Background Art

[0002] The clutch hub of a car transmission is an important component in the car transmission system. It is located between the flywheel housing of the engine and the input shaft of the transmission. It is responsible for connecting the power output of the engine and the transmission to achieve power transmission. The clutch hub is equipped with a clutch plate and a pressure plate. When the driver steps on the clutch pedal, the clutch plate and the pressure plate will separate, temporarily disconnecting the engine and the transmission to achieve power cutoff. When the driver releases the clutch pedal, the clutch plate and the pressure plate will combine to reconnect the engine and the transmission to achieve power transmission. The function of the clutch hub is to ensure the smoothness of power transmission and the smooth start of the vehicle.

[0003] During the use of the clutch, lubricating oil needs to be provided to the friction plate group to lubricate and cool the friction plate group. In the prior art, an oil guide hole is generally opened on the clutch hub, so that after the lubricating oil flows into the oil guide hole, under the action of centrifugal force, some of the lubricating oil enters the friction plate group through the oil guide hole to achieve the lubrication effect on the friction plate group. However, since the oil guide hole is fixed, the position reached by the lubricating oil under the action of centrifugal force is fixed each time, resulting in uneven distribution of the lubricating oil and reduced lubrication efficiency. For this purpose, a transmission clutch hub is designed. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a transmission clutch hub.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transmission clutch hub comprises a clutch hub body, an inner hole is opened in the middle of the clutch hub body, a plurality of fan-shaped holes are opened at equal distances on the circumferential outer surface of the clutch hub body, rectangular grooves are opened on both sides of each of the fan-shaped holes, an oil guide cover is rotatably connected to one end of each fan-shaped hole close to the inner hole, and the oil guide cover is adapted to the fan-shaped hole, curved grooves are opened on both sides of the outer wall of the oil guide cover, and a rotating mechanism is arranged on each of the rectangular grooves.

[0007] As a further solution of the utility model, the rotating mechanism includes a sliding rod fixedly connected between the top and bottom of the rectangular groove, a counterweight block is slidingly sleeved on the circumferential surface of the sliding rod, a circular hole matching the sliding rod is opened on the counterweight block, one end of the counterweight block close to the oil guide cover is fixedly connected to the sliding block, and the other end of the sliding block is slidably connected to the adjacent curved groove, and the end of the sliding rod away from the circumferential surface of the inner hole is sleeved with a spring. The setting of the spring ensures that when the centrifugal force of the clutch hub body is insufficient, the counterweight block can move quickly under the action of the spring and will not be stable in one position, making the oil guide cover more likely to rotate.

[0008] As a further solution of the utility model, a plurality of oil guide grooves are provided at equal distances on the inner hole, and one end of each oil guide groove located inside the inner hole is connected to the corresponding fan-shaped hole, and a chamfer is provided at the outer end of each oil guide groove. The chamfer is provided to facilitate the entry of lubricating oil.

[0009] As a further solution of the present invention, a plurality of racks are fixedly connected to the outer circumferential surface of the clutch hub body at equal distances.

[0010] As a further solution of the utility model, a plurality of tooth grooves are provided at equal distances on the surface of the inner hole.

[0011] As a further solution of the utility model, a plurality of oil guide holes are provided at equal intervals on the side surface of the clutch hub body.

[0012] The beneficial effects of the utility model are:

[0013] The utility model adopts the technical means of rectangular groove, oil guide cover, curved groove, sliding rod, spring, counterweight block and sliding block, and the lubricating oil enters the bottom of the fan-shaped hole through the oil guide groove. Since the bottom of the fan-shaped hole is rotatably connected with the oil guide cover, the lubricating oil enters the oil guide cover under the action of centrifugal force and is sprayed out from the outer end of the oil guide cover. At the same time, due to the rotation of the clutch hub body, multiple counterweight blocks slide outward along the sliding rod under the action of centrifugal force, so that the counterweight blocks are away from the inner hole. Due to the arrangement of the sliding block and the curved groove, the oil guide cover has different directions when the counterweight blocks are in different positions. At the same time, with the spring, the centrifugal force of the clutch hub body is different when the speed is different, so that the spraying angle can be changed at any time, and the spraying range of the lubricating oil can be larger, which effectively solves the problems raised in the background technology, and then realizes the real-time change of the lubricating oil outlet direction according to the speed of the clutch hub body and the centrifugal force, so that the contact range of the lubricating oil and the friction plate group is larger, the lubrication efficiency is higher, and the practical technical effect is improved.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Reference Figure 1-Figure 3 A transmission clutch hub comprises a clutch hub body 1, an inner hole 101 is opened in the middle of the clutch hub body 1, a plurality of fan-shaped holes 3 are opened at equal distances on the circumferential outer surface of the clutch hub body 1, rectangular grooves 301 are opened on both sides of each fan-shaped hole 3, an oil guide cover 4 is rotatably connected to one end of each fan-shaped hole 3 close to the inner hole 101, and the oil guide cover 4 is adapted to the fan-shaped hole 3, curved grooves 401 are opened on both sides of the outer wall of the oil guide cover 4, and a rotating mechanism is arranged on each rectangular groove 301.

[0021] In this embodiment, the rotating mechanism includes a sliding rod 5 fixedly connected between the top and bottom of the rectangular groove 301, and a counterweight block 502 is slidingly sleeved on the circumferential surface of the sliding rod 5. The counterweight block 502 is provided with a circular hole adapted to the sliding rod 5, and one end of the counterweight block 502 close to the oil guide cover 4 is fixedly connected to a sliding block 503, and the other end of the sliding block 503 is slidingly connected to the adjacent curved groove 401. Through the cooperation of the sliding block 503 and the curved groove 401, when the counterweight block 502 moves, the oil guide cover 4 will definitely rotate, and one end of the sliding rod 5 away from the circumferential surface of the inner hole 101 is sleeved with a spring 501. The setting of the spring 501 enables the counterweight block 502 to move quickly under the action of the spring 501 when the centrifugal force of the clutch hub body 1 is insufficient, and will not be stable in one position, making the rotation possibility of the oil guide cover 4 greater.

[0022] In this embodiment, a plurality of oil guide grooves 2 are provided at equal distances on the inner hole 101, and one end of each oil guide groove 2 located inside the inner hole 101 is connected to the corresponding fan-shaped hole 3, and a chamfer is provided at the outer end of each oil guide groove 2. The setting of the oil guide groove 2 facilitates the lubricating oil to enter the fan-shaped hole 3, and the setting of the chamfer further improves the convenience of the lubricating oil entering.

[0023] In this embodiment, a plurality of racks 102 are fixedly connected at equal distances to the outer circumferential surface of the clutch hub body 1, and the arrangement of the racks 102 is adapted to the friction plate.

[0024] In this embodiment, a plurality of tooth grooves 103 are equidistantly provided on the surface of the inner hole 101 . The tooth grooves 103 are arranged so as to mesh with the teeth on the bearing, thereby facilitating stable sliding of the clutch hub body 1 .

[0025] In this embodiment, a plurality of oil guide holes 104 are provided at equal intervals on the side surface of the clutch hub body 1. The provision of the oil guide holes 104 allows the lubricating oil to flow more easily.

[0026] Working principle: When in use, the transmission clutch hub is slidably sleeved on the gearbox bearing through the tooth slot 103 and the inner hole 101. The setting of the oil guide hole 104 allows the lubricating oil to pass through the oil guide hole 104, so that the lubrication between the two sides of the clutch hub body 1 is balanced. Through the setting of the oil guide groove 2, when the clutch hub body 1 rotates with the bearing, the lubricating oil enters the bottom of the fan-shaped hole 3 through the oil guide groove 2. Since the bottom of the fan-shaped hole 3 is connected to the oil guide cover 4, the lubricating oil enters the oil guide cover 4 under the action of centrifugal force and The oil is sprayed out from the outer end of the oil guide cover 4. At the same time, due to the rotation of the clutch hub body 1, multiple counterweights 502 slide outward along the slide bar 5 under the action of centrifugal force, so that the counterweights 502 are away from the inner hole 101. Due to the arrangement of the sliding block 503 and the curved groove 401, the orientation of the oil guide cover 4 is different when the counterweights 502 are in different positions. At the same time, with the spring 501, the centrifugal force of the clutch hub body 1 is different at different speeds, thereby realizing the change of the spraying angle at any time and achieving a larger spraying range of the lubricating oil.
