Description

Technical Field

[0001] The utility model relates to the technical field of automobile transmission system components, in particular to a torque transmission flange for automobiles. Background Technique

[0002] The torque transmission flange for automobiles is an important component in the automobile transmission system. It is usually located between the drive shaft and other components (such as the differential, transmission, etc.), and plays a role in connecting and transmitting torque. Ensure that power can be effectively transmitted from the engine to the wheels, enabling the automobile to drive normally.

[0003] The existing torque transmission flange for automobiles still has the following problems in use: The torque transmission flange is usually arranged on the hub body. The internal spline hole of the hub body is usually connected to the output spline shaft of the gearbox. However, the hub body is usually of a disc structure, and a multi-stage groove is provided at the front end of the hub body. The actual depth of the spline hole opened is limited. After it is connected to the output spline shaft of the gearbox, the contact area with the output spline shaft of the gearbox is limited. When it bears torque, the pressure on the protruding part inside the spline hole is relatively large, and the protruding part inside the spline hole is extremely easy to be damaged by pressure. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the utility model provides a torque transmission flange for automobiles, which solves the problems put forward in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A torque transmission flange for automobiles, including a torque transmission mechanism. The torque transmission mechanism includes a hub body. Two rows of strip-shaped grooves are symmetrically arranged up and down on the outer side of the top of the hub body. Each row of strip-shaped grooves includes two groups of strip-shaped grooves arranged symmetrically. Each group of strip-shaped grooves is multiple and arranged at equal angles in an arc shape. An installation hole is provided in the middle of each group of strip-shaped grooves. The installation hole penetrates through the upper and lower ends of the hub body. A main spline hole is provided at the center position of the bottom wall of the hub body. A sleeve is fixedly connected to the bottom wall of the hub body and outside the main spline hole. An auxiliary spline hole is provided in the middle of the sleeve. The auxiliary spline hole is coaxially arranged with the main spline hole and has the same aperture.

[0006] As a further scheme of the utility model: A first groove is provided at the center position of the top wall of the hub body. A second groove is provided at the center position of the bottom wall of the first groove. A third groove is provided at the center position of the bottom wall of the second groove. A fourth groove is provided at the center position of the bottom wall of the third groove. The main spline hole penetrates through the center position of the bottom wall of the fourth groove.

[0007] As a further scheme of the utility model: A reinforcing ring is fixedly sleeved on the outer side wall above the sleeve. The top end of the reinforcing ring is fixedly connected to the bottom end of the hub body.

[0008] As a further solution of the present utility model: on the outer side wall above the reinforcement ring, four reinforcement blocks are fixedly connected at equal angles, and the tops of the four reinforcement blocks are fixedly connected to the bottom end of the hub body.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
