The invention discloses a combined third-gear and fourth-gear shifting transmission fork of an automobile. The combined third-gear and fourth-gear shifting transmission fork of the automobile comprises a transmission fork body (1) which is provided with a transmission fork shaft mounting hole (4), wherein a fork port (5) which is leftwards opened is formed in the upper left side of the transmission fork body (1); a right transmission fork arm (2) and a left transmission fork arm (3) are symmetrically arranged at the lower side of the transmission fork body (1); a semicircular transmission fork opening is formed in the right transmission fork arm (2), the transmission fork body (1) and the left transmission fork arm (3); frictional sleeve heads (7) sleeve the front ends of the right transmission fork arm (2) and the left transmission fork arm (3); a frictional sheet (6) is arranged at the bottom part of the transmission fork opening. According to the combined third-gear and fourth-gear shifting transmission fork of the automobile, the frictional sleeves sleeve the front ends of the transmission fork arms, and the frictional sheet is arranged at the bottom part of the opening, so that the service life of the transmission fork can be effectively prolonged; the surfaces of the frictional sleeves and the frictional sheet are plated with chrome, so that the abrasion resistance of the transmission fork can be further improved.
Description
technical field [0001] The invention relates to the technical field of gear shifting of motor vehicles, and relates to a shift fork which reduces wear of a shift fork hole and a tooth collar, in particular to a combined shift fork for third and fourth gears of an automobile. Background technique [0002] The shift fork is a part of the auto parts. It is mainly used to push the sliding gear. There is a ring groove on the sliding gear. The shift fork rides in this ring groove. When the driver pushes the shift lever, the shift lever drives the shift fork shaft. The fork shaft drives the shift fork, and the shift fork pushes the gear to achieve gear shifting. The existing shift forks are prone to friction with the gears, the wear of the shift forks is relatively serious, the overall strength of the shift forks is relatively low, frequent breakage occurs, and the safety factor is relatively low, which shortens the service life of the shift forks and greatly reduces the risk of st...
