きる限り摩耗粉がでないことを要求されている。 Generally, a shift fork is used to change the meshing of gears in a transmission, and this shift fork changes the meshing of the gears via a sleeve. In recent years, with the shift to no oil changes, abrasion particles generated on the friction surfaces between the shift fork and the sleeve in the oil are causing damage to the bearings. This tendency is particularly strong after long-term use, and it is required that wear particles be produced as little as possible.

上に摩耗していることが判明した。 Therefore, when we closely observed the wear status of the shift fork, we found that the friction surfaces where the shift fork and the sleeve come into contact are provided at two places on the left and right, and the line connecting their centers passes through the center of the sleeve. The shift fork is tilted against the
It was discovered that the pads that make up the friction surface were worn at their edges more than expected.

を目的とする。 In order to prevent the tilting caused by the structure of the conventional shift fork, the present invention is characterized by having three friction surfaces where the shift fork and the sleeve come into contact, resulting in a simple structure and less friction powder. The purpose is to provide a shift fork for transmission.

かまわない。 This embodiment shows a shift fork 1 used in an automobile transmission, and although not shown, changes the meshing of the gears of the transmission to determine the reduction ratio of the gear train. This shift fork 1 switches the meshing of gears via a hub sleeve 2 indicated by a two-dot chain line in the figure. The shift fork 1 and the hub sleeve 2 are fitted together by inserting the bifurcated leg portion 4 of the shift fork 1 into a groove 3 formed on the outer periphery of the hub sleeve. In this case, the friction surfaces 5 and 6 where the leg portion 4 and the groove 3 come into contact are formed with pads made of a wear-resistant material. That is, the friction surfaces 5 are located at both ends of the shift fork 1, and are offset H in the direction of the ends with respect to the center O of the hub sleeve 2, as shown in FIG. Further, the other friction surface 6 is located at the base of the shift fork 1 and is located at the base of the shift fork 1.
At the same time, the sleeve 2 is pressed and moved. The material of this friction surface 6 may be conventional steel, cast iron, aluminum alloy, etc., or it may be a new piece of plastic.

摩擦面にバランスさせることも容易となる。 Therefore, compared to the conventional model which has friction surfaces at two places on the left and right sides, since the friction surfaces are provided at three places, it is possible to make a three-point contact that is less likely to tilt, and the force applied to the root friction surface is also applied to the other friction surfaces. Since the inclination is further reduced by the offset, it becomes easier to balance the three friction surfaces.

効果大なるものがある。 As described above, according to the configuration of the present invention, the friction surfaces of the shift fork and the groove of the sleeve are brought into three-point contact, and both friction surfaces of the tip of the shift fork are offset in the tip direction with respect to the center of the sleeve. The simple structure prevents the sleeve and shift fork from tilting, reducing wear on the friction surfaces, allowing the sleeve to slide smoothly, and reducing wear particles in the oil. It has great effects as a maintenance-free technology.
