Description

Technical Field

[0001] The invention belongs to the technical field of transmissions, and in particular relates to a dual-mass flywheel clamp. Background Art

[0002] Due to the structural limitations of the traditional clutch itself, the torsional stiffness of the vibration reduction system is large and the vibration isolation rate is low under the premise of meeting the torque transmission capacity. NVH problems such as abnormal noise at idle, acceleration resonance and acceleration roar are prone to occur. The use of a dual-mass flywheel can greatly reduce the torsional stiffness and the vibration isolation rate can reach more than 70%, meeting the needs of reducing the torsional vibration and noise of the vehicle power transmission system and the increasing comfort requirements. However, when assembling the dual-mass flywheel on the production line, manual installation is adopted, which is difficult, inefficient and unstable. Summary of the invention

[0003] In order to solve the problem of workers manually installing a dual-mass flywheel, the present invention further provides a dual-mass flywheel clamp. The clamp is used during the assembly process, and the hole positions are aligned using production line equipment, which can achieve the purpose of convenient, safe, stable and efficient installation.

[0004] The technical solution adopted by the present invention is:

[0005] A dual-mass flywheel clamp comprises a clamp body, two clamp side arms and two limit blocks; the two clamp side arms are both concave structures and are arranged opposite to each other, and sockets are provided on the relative concave surfaces of the two clamp side arms, one end of the two limit blocks are respectively connected to the clamp side arms through the sockets, and the other ends of the two limit blocks are respectively used to be inserted into the limit grooves of the dual-mass flywheel, and the two clamp side arms are slidably connected through the clamp body.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The present invention is suitable for the assembly of dual-mass flywheels on production lines. The limit block of the clamp cooperates and extends into the limit groove of the dual-mass flywheel to form fixation and clamping. The positioning tool extends into the positioning hole of the clamp to ensure the accuracy of the dual-mass flywheel and the crankshaft during assembly. The invention is easy to implement and is convenient and efficient.

[0008] The present invention is used in the assembly process to facilitate workers to quickly, safely and stably install the dual-mass flywheel, thereby improving efficiency and ensuring accurate assembly.

[0009] The present invention avoids complex structures, is easy to install and use, and the consumable parts are easy to replace. The limit points of dual-mass flywheels of different forms and sizes can be changed through the sliding structure, and the applicability is wider. At the same time, the present invention has positioning holes, so that the dual-mass flywheel can be accurately matched with the crankshaft during the assembly process. The assembly steps of the production line are improved to facilitate the operation of workers, so as to achieve the purpose of convenience, efficiency, safety and stability.

[0017] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0018] like Figure 1 to Figure 6 As shown, the present invention provides a dual-mass flywheel clamp, including a clamp body 101, two clamp side arms 102 and two limit blocks 103; the two clamp side arms 102 are both concave structures and are arranged opposite to each other, and sockets 107 are provided on the relative concave surfaces of the two clamp side arms 102, one end of the two limit blocks 103 is respectively connected to the clamp side arms 102 through the sockets 107, and the other ends of the two limit blocks 103 are respectively used to be inserted into the limit grooves of the dual-mass flywheel 2, and the two clamp side arms 102 are slidably connected through the clamp body 101.

[0019] like Figure 2 As shown, the middle portion of the clamp body 101 is an arc portion 108 , which is concentrically arranged with the dual mass flywheel 2 , and both ends of the clamp body 101 are straight connecting portions 109 for connecting with the clamp side arms 102 .

[0020] like Figure 1 As shown, the portion where each of the clamp side arms 102 is connected to the clamp body 101 is configured as a T-shaped plug block 106 , and the connecting portion 109 of the clamp body 101 is provided with a slot 105 matching the T-shaped plug block 106 .

[0021] A plurality of steel ball locking mechanisms are provided between the T-shaped plug block 106 and the slot 105 to achieve multiple locking positions and locking positioning.

[0022] The steel ball locking mechanism adopts the existing mechanism, that is, the steel ball and the spring are arranged in the installation groove set in the T-shaped plug block 106, and then the corresponding fixing groove is arranged on the connecting surface of the slot 105. In the process of the T-shaped plug block 106 and the slot 105 sliding against each other, the steel ball can be pushed out by the spring and inserted into the fixing groove of the slot 105 to fix the T-shaped plug block 106 and the slot 105, or compressed by the slot 105 back into the installation groove set in the T-shaped plug block 106.

[0023] like Figure 1 As shown, a positioning hole 104 is provided on the side wall of each of the clamp side arms 102 .

[0024] First, assemble the clamp body 101, the clamp side arm 102 and the limit block 103 (as shown in FIG. Figure 2 There are multiple clamping points available at the joint of the clamp body 101 and the clamp side arm 102, which are stretched to the maximum limit to ensure that the dual mass flywheel 2 can be smoothly assembled with the clamp. Then, adjust the dual mass flywheel 2 and the direction of the clamp so that the limit block 103 of the clamp is stuck in the limit groove of the dual mass flywheel 2, so that the clamp is locked in the axial direction of the dual mass flywheel 2. At the same time, adjust the clamping point so that the clamp is locked in the radial direction of the dual mass flywheel 2 (such as Figure 4 After the two are assembled successfully, the positioning tool is inserted into the fixture positioning hole 104, and the assembly machine of the production line will align the pin hole and bolt hole on the dual mass flywheel 2 and the crankshaft 3 and screw in the bolt 4, such as Figure 6 After the dual-mass flywheel 2 is installed, the clamp can be removed by pulling the side arms 102 of the clamp outward.
