Technical Field

[0001] The utility model belongs to the technical field of automobile accessories and relates to an accessory of a torque damper, in particular to a disc hub for the torque damper. Background Art

[0002] Currently, the disc hub for torque damper is an integral structure, which includes a flange and a disc hub core located in the center of the flange. The disc hub core is cylindrical and both ends of the disc hub core axially protrude from the corresponding end surface of the flange.

[0003] During manufacturing, the rods are forged by a large-tonnage forging machine, which results in high manufacturing costs. Furthermore, during heat treatment, the blanks need to be laid flat or staggered to prevent the blanks from overlapping and blocking the through holes of the hub core, making it impossible to pour oil into the through holes of the hub core, so as to ensure that the hub core of the blank after heat treatment has sufficient structural strength. This increases the labor intensity of the workers and the heat treatment time, resulting in low processing efficiency and high manufacturing costs. In addition, the amount of turning of the flange is large and the material utilization rate is low. Summary of the invention

[0004] The utility model aims to solve the above problems existing in the prior art and to provide a disc hub for a torque damper which has high material utilization and is easy to manufacture.

[0006] In the above-mentioned disc hub for torque damper, the connection structure includes a plurality of circumferentially evenly distributed riveted teeth on the outer wall of the disc hub core, and the flange has grooves for accommodating the corresponding riveted teeth.

[0007] As a second case, in the above-mentioned disc hub for torque damper, the connection structure includes welding rings at the joints between the disc hub core and the two end surfaces of the flange.

[0008] As a third case, in the above-mentioned disc hub for torque damper, the connection structure includes teeth evenly distributed circumferentially on the outer wall of the disc hub core, and the flange has a groove for each tooth to be inserted into, and the groove width of the groove is greater than the tooth width of the tooth.

[0009] In the above-mentioned hub for torque damper, the hub core has an inner spline hole.

[0010] In the above-mentioned disc hub for torque damper, the flange is axially penetrated by a plurality of through holes arranged around the disc hub core.

[0011] In the above-mentioned disc hub for torque damper, the flange plate is axially penetrated by a plurality of windows evenly distributed in the circumferential direction.

[0012] Compared with the prior art, the torque damper is manufactured by splitting the disc and the hub, which is convenient to manufacture, has a high material utilization rate, and has good heat treatment efficiency and effect, and low manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example 1

[0021] like Figure 1 and Figure 2 As shown, the disc hub for the torque damper includes a disc-shaped flange 1, a split disc hub core 2 is axially penetrated at the center of the flange 1, the disc hub core 2 is connected to the flange 1 through a connecting structure, the disc hub core 2 is cylindrical, and both ends of the disc hub core 2 protrude axially from the corresponding end faces of the flange 1.

[0022] The torque damper uses a disc hub flange 1 and a disc hub core 2 that are manufactured separately. The flange 1 is manufactured by stamping or cutting a plate, which is convenient to manufacture, requires little turning, and has a high material utilization rate. Moreover, the flange 1 and the disc hub core 2 are heat treated separately, so there is no problem in the past where the through hole of the disc hub core 2 is blocked and oil cannot be filled. The heat treatment efficiency and effect are good, and the manufacturing cost is reduced.

[0023] In this embodiment, the connection structure includes a plurality of circumferentially evenly distributed riveting teeth 3 on the outer wall of the hub core 2, and the flange 1 has grooves for accommodating the corresponding riveting teeth 3. The hub core 2 axially passes through the flange 1, and the riveting teeth 3 are located in the corresponding grooves. Then, the riveting teeth 3 are riveted, so that the riveting teeth 3 are deformed and fastened in the grooves, thereby completing the fixed connection between the hub core 2 and the flange 1.

[0024] The flange 1 is axially penetrated by six through holes 7 arranged around the hub core 2, which play the role of avoidance and weight reduction. The flange 1 is axially penetrated by four circumferentially evenly distributed windows 8, which play the role of avoidance and facilitate the installation of the spring. The hub core 2 has an internal spline hole 9, which can increase the connection strength, have a strong load-bearing capacity, reduce stress concentration, and provide good torque transfer capability. Example 2

[0025] like Figure 3 and Figure 4 As shown, the structure and principle of this embodiment are basically the same as those of the first embodiment, except that the connection structure in this embodiment includes welding rings 4 at the junction of the hub core 2 and the two end surfaces of the flange 1. After the hub core 2 passes through the flange 1, two welding rings 4 are formed by welding to weld the hub core 2 and the flange 1 together. Example 3

[0026] like Figure 5 and Figure 6 As shown, the structure and principle of this embodiment are basically the same as those of the embodiment 1, except that the connection structure in this embodiment includes teeth 5 uniformly distributed on the outer wall of the hub core 2 in the circumferential direction, and the flange 1 has a slot 6 for each tooth 5 to be inserted into, and the slot width of the slot 6 is greater than the tooth width of the tooth 5. The hub core 2 and the flange 1 are connected by tooth matching, and the slot width of the slot 6 is greater than the tooth width of the tooth 5, which has a delay effect when in use to meet different driving requirements.
