Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a novel spliced ​​automobile coupling. Background Art

[0002] Couplings play an important role in automobiles. They are mainly used to connect the engine and wheel transmission system to ensure efficient power transmission and smooth operation of the car.

[0003] Chinese Utility Model Publication No. CN217440623U comprises a left half, a middle buffer, and a right half. The left half and right half have identical structures. The left half includes a toothed portion and a connecting tube. The toothed portion comprises a body having at least two raised portions, a mating groove formed between adjacent raised portions, and a mounting hole formed in the body. The connecting tube is inserted into the mounting hole and is welded to the body to secure the connecting tube to the toothed portion. This spliced ​​coupling boasts high processing efficiency, low production costs, high overall strength, and stable and reliable quality.

[0004] The applicant found that this patent had some shortcomings during use: the coupling's claws would be affected by factors such as rotational speed and load during long-term use, and would be prone to wear and tear and need to be replaced. However, since the mating grooves and protrusions were fixedly installed, it was not convenient to replace the damaged claws, and the overall replacement cost was relatively high.

[0005] Therefore, the utility model designs a novel spliced ​​automobile coupling to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of the present utility model is to provide a novel spliced ​​automobile coupling to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a novel spliced ​​automobile coupling, comprising: two connecting rings, a shaft cylinder is provided on one side of the connecting ring, a plum blossom elastic part is provided between the two connecting rings, and claws are provided around the other side of the connecting ring that engage with the plum blossom elastic part, a latch is installed on one side of the claw, a slot is provided on one side of the connecting ring to be plugged into the claw, a threaded hole 1 is provided on one side of the latch, and a threaded hole 2 is provided on the side of the connecting ring away from the slot to communicate with the slot, a screw is installed on the threaded hole 1 and the threaded hole 2 through threaded rotation, the claw can be formed by laser cutting and splicing the claw and the connecting ring. When a claw is worn and needs to be replaced, there is no need to replace the entire claw, only the worn claw needs to be replaced, thereby reducing the replacement cost.

[0008] Preferably, the connecting ring and the shaft cylinder are connected by welding. By welding, the shaft cylinder and the connecting ring are spliced ​​together. Compared with the traditional one-piece casting method, quality defects such as pores and cracks can be reduced.

[0009] Preferably, the latch is a regular hexagonal prism, and the slot is a regular hexagonal groove. The regular hexagonal prism is inserted into the regular hexagonal groove, which can improve the stability of the claw.

[0010] Preferably, the connecting ring and the shaft cylinder are both made of seamless steel pipes, which have high strength, corrosion resistance and good sealing performance, and can improve the strength and quality of the coupling.

[0011] Preferably, a circular groove connected to the second threaded hole is opened on one side of the connecting ring, and a hexagonal head is installed on one side of the screw. The hexagonal head is convenient for the staff to use a hexagonal wrench to screw the screw, and the circular groove is convenient for storing the hexagonal head.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. When a cam is worn and needs to be replaced, the hexagonal wrench can be used to twist the hexagonal head and unscrew the screw from between the first and second threaded holes. Then the damaged cam and the pin connected to it can be pulled out from the slot for replacement. The replacement is convenient, and only the damaged cam needs to be replaced separately, without replacing the entire cam, which saves the cost of replacement. BRIEF DESCRIPTION OF THE DRAWINGS
