Embodiment Construction

[0020] There are welding forks with various tooth shapes on the lower plane. There are two concentric holes on the upper end, which require high precision. They are used for the connection of the cross shaft. There are four threaded holes on the lower end to connect with the car transmission shaft. Below the concentric holes is a semicircular raised structure. , this structure can increase the strength of the part; on the lower plane of the welding fork, there are four threaded hole positions, there are four raised planes, and various tooth shapes that can increase the connection strength and reliability are milled out on the four raised planes .

[0021] The present invention is characterized in that the bottom plane of the welding fork has four small planes higher than the bottom plane at the four screw holes, the length is 35mm, and the distance between the two convex surfaces is 60mm.

[0022] The present invention is characterized in that various tooth shapes are milled o...

Abstract

The invention relates to a welding fork with the lower surface provided with multiple tooth forms, which belongs to the core technological field of transmission pats of automobile transmission shafts. The welding fork provided by the invention is mainly applied to transmission shaft connecting parts of heavy load automobiles such as an automobile bearing high torque load and the like and is particularly applied to innovated and improved in structure to meeting requirements for increasing torque of the transmission shaft connecting parts of automobiles; according to the adoption of the innovation and improvement of the structure, two concentric holes are arranged at the upper end of welding fork, the required precision is high, a cross shaft is connected with the automobile transmission shafts by four screw holes arranged at the lower end of the welding fork, a semi-circle raised structure is arranged below the two concentric holes and can enhance the strength of parts; four raised planes are arranged at the positions of the four screw holes in the lower plane of the welding fork; and the multiple tooth forms which can enhance the strength and the reliability are milled on the four raised planes.

Description

technical field [0001] The invention relates to the core technical field of transmission parts of automobile transmission shafts, and is mainly used in heavy-duty automobiles such as automobile transmission shaft connectors that bear high torque loads. Specifically, it aims at increasing the torque demand of automobile transmission shaft connection parts, and adopts structural innovation and improvement There are welding forks with various tooth shapes on the lower plane. Background technique [0002] Generally, the two ends of the steering transmission shaft of an automobile are connected to the cross shaft by a welded fork structure with ear holes, and the power is transmitted for rotation. The main problem is that the lower plane of the welding fork is in the shape of a plane. During the steering process, the matching plane is connected with screws. During the driving process of the car, the contact planes slide against each other, causing insufficient power transmission....
