Description

Technical Field

[0001] The utility model relates to the technical field of torque transmission shafts, in particular to a torque transmission shaft with a replaceable connector. Background Technique

[0002] The vehicle driveline transfers torque or power from a drive source (e.g., an internal combustion engine) to the vehicle wheels, and the torque or power can be transmitted through a series of driveline components (e.g., gears, couplings, and shafts), which provide a certain level of torsional stiffness to meet performance requirements.

[0003] When the torque transmission shaft is in use, both ends are connected through connectors so that the torque can be transmitted. After long-term use, the connectors will be worn, damaged, or need to be replaced. However, most torque transmission shafts integrate the connectors with the shaft body, so the connectors cannot be replaced separately.

[0004] Therefore, those skilled in the art have provided a torque transmission shaft with a replaceable connector to solve the problems raised in the above background technique. Content of the Utility Model

[0012] As a further solution of the utility model: A sealing gasket is fixedly connected to the left side surface of the connection head, and the left side surface of the sealing gasket is in contact with the right side surface of the transmission shaft.

[0013] As a further solution of the utility model: Two limit pin shafts are arranged on the outer surface of the connection head, and the mutually approaching ends of the two limit pin shafts sequentially penetrate through the connection head and the serrated ring and extend into the interior of the connection column.

[0014] As a further solution of the utility model: A protective sleeve is sleeved on the outer surface of each of the limit pin shafts, and the mutually approaching side surfaces of the two protective sleeves are in contact with the outer surface of the connection head.

[0022] Please refer toFigures 1-4 , a torque transmission shaft with a replaceable connector, including a transmission shaft 1, and a connection structure 2 is arranged on the right side of the transmission shaft 1;

[0023] The connection structure 2 includes a connector 201. A connection column 205 is fixedly connected to the right end of the transmission shaft 1. Serrated rings 204 are fixedly connected to the outer surface of the connection column 205 and the inner wall of the connector 201. The two serrated rings 204 are meshed with each other. Fixed rings 203 are fixedly connected to the outer surfaces of the transmission shaft 1 and the connector 201. Threaded pin shafts 202 arranged at equal distances are arranged on the right side of one of the fixed rings 203. Each threaded pin shaft 202 threadedly penetrates through the fixed ring 203 and extends to the left side of the other fixed ring 203.

[0024] Specifically, a limit hole 7 is opened inside the connection column 205, and a limit frame 8 is fixedly connected to the inner wall of the connector 201. The outer surface of the limit frame 8 is in contact with the inner wall of the limit hole 7.

[0025] Through the above technical solution, by cooperating the limit frame 8 with the limit hole 7, the connection column 205 can be limited when connected to the connector 201, improving the connection stability.

[0026] Specifically, reinforcing plates 4 arranged at equal distances are fixedly connected to the outer surfaces of the transmission shaft 1 and the connector 201. One side of each group of reinforcing plates 4 close to each other is fixedly connected to one side of the two fixed rings 203 away from each other.

[0027] Through the above technical solution, by the reinforcing plates 4, the connection between the fixed ring 203 and the transmission shaft 1 and the connector 201 can be strengthened, improving the firmness during use.

[0028] Specifically, a protective threaded cap 3 is threadedly connected to the outer surface of each threaded pin shaft 202, and the right side surface of each protective threaded cap 3 is fixedly connected to the left side surface of the other fixed ring 203.

[0029] Through the above technical solution, by the protective threaded cap 3, the fixed length of the threaded pin shaft 202 can be extended, further improving the fixing stability.

[0030] Specifically, a sealing gasket 9 is fixedly connected to the left side surface of the connector 201, and the left side surface of the sealing gasket 9 is in contact with the right side surface of the transmission shaft 1.

[0031] Through the above technical solution, by using the sealing gasket 9, it can be squeezed between the connector 201 and the transmission shaft 1, thereby sealing the connection part.

[0032] Specifically, two limit pin shafts 6 are arranged on the outer surface of the connector 201. One ends of the two limit pin shafts 6 close to each other sequentially penetrate through the connector 201 and the serrated ring 204 and extend into the inside of the connection column 205.

[0033] Through the above technical solution, by using the limit pin shaft 6, it can penetrate between the connector 201, the serrated ring 204 and the connection column 205, thereby improving the stability of torque transmission.

[0034] Specifically, a protective sleeve 5 is sleeved on the outer surface of each limit pin shaft 6, and one side surface of the two protective sleeves 5 close to each other is in contact with the outer surface of the connector 201.

[0035] Through the above technical solution, by using the shape of the protective sleeve 5, it can closely adhere to the circular outer surface of the connector 201, so that the connection between the connection column 205 and the connector 201 can be more stable.

[0036] The working principle of the present utility model is as follows: When in use, first, move the connector 201 to a suitable position. When it is necessary to assemble and replace the transmission shaft 1 and the connector 201, align the limit hole 7 and the limit frame 8, and move the limit frame 8 into the limit hole 7. Then, make the two serrated rings 204 engage with each other. At the same time, sleeve the connector 201 on the outside of the connection column 205. When moving to the point where the sealing gasket 9 contacts the transmission shaft 1, by rotating the threaded pin shaft 202, move the two fixing rings 203 closer to each other and thread them into the internal thread of the protective thread cap 3 until the two fixing rings 203 contact each other. After fixation, sleeve the protective sleeve 5 on the limit pin shaft 6, and penetrate the limit pin shaft 6 through the connector 201 and the serrated ring 204 and fix it in the connection column 205, so as to assemble and replace the transmission shaft 1 and the connector 201.

[0037] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
