Abstract

The invention provides a universal joint fork comprising a joint fork mounting head, fork lugs and a reinforcing locking hoop, the two fork lugs are symmetrically arranged above the joint fork mounting head, the joint fork mounting head comprises a long side fixing seat and a short side fixing seat which are symmetrically arranged, and a locking opening groove is formed between the long side fixing seat and the short side fixing seat. The long side fixing seat and the short side fixing seat are connected through a plurality of first fastening bolts to lock a transmission shaft in a mounting cavity, a reinforcing locking hoop is connected with the long side fixing seat through a plurality of second fastening bolts to lock the transmission shaft in the mounting cavity, an anti-release limiting groove is formed in the inner circumferential wall of the reinforcing locking hoop, and the transmission shaft is provided with an anti-release clamp matched with the anti-release limiting groove. The transmission shaft is locked through the fastening bolts on the two sides, so that the transmission shaft is stressed more uniformly. Secondary locking can be achieved through the first fastening bolts and the second fastening bolts. The anti-release clamp is additionally arranged, so that the problem of looseness of the transmission shaft due to vibration is avoided.

Description

【Technical field】 [0001] The invention relates to the technical field of universal joint parts, in particular to a universal joint fork. 【Background technique】 [0002] In the automobile steering system, the universal joint fork is used to connect the input shaft of the steering wheel and the universal joint. The universal joint fork is roughly U-shaped, the U-shaped bottom is called the fork head, and the groove walls on both sides are called fork lugs. Connecting holes for knuckles. Usually, one side of the through hole of the fork is provided with a groove, and the force on one side of the universal joint is severely uneven; and the joint between the universal joint and the transmission shaft may become loose and fall off after a long period of use. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a universal joint yoke capable of accurate positioning, ensuring uniform force, and effectively lo...
