Abstract
The utility model discloses a thrust gasket of shifting that manual transmission used. The gear shifting thrust washer is small in friction factor and long in service life. The plain sliding bearing is a circular ring plain sliding bearing with a round hole in the center, wherein a copper alloy layer is sintered on one surface of a steel plate, and a concave oil hole and/or oil groove is pressed on the surface of the copper alloy layer. When the manual transmission is used, the gear-shifting thrust washer is sleeved on the spline shaft, and the convex claws are clamped in the spline grooves, so that the gear-shifting thrust washer and the spline on the shaft cannot generate relative circumferential rotation motion, abnormal sound and abnormal abrasion of the inner hole of the spline-swapping stop-push washer are eliminated, and the service life of the manual transmission is prolonged. The oil holes and the oil grooves improve the lubricating performance between the friction pairs, and the process is very simple as long as the friction pairs are directly extruded during manufacturing.
Description
Technical Field
The utility model relates to a slide bearing further includes the thrust gasket of shifting that manual transmission used.
Background
The existing manual transmission gear shifting thrust washer is mostly made of single spring steel materials, the surface of the existing manual transmission gear shifting thrust washer is not provided with an oil groove, the existing manual transmission gear shifting thrust washer is sleeved on a shaft in an unfixed circumferential direction, and two adjacent gear end faces are separated. In the gear shifting process, the thrust washer is not fixed in the circumferential direction, so that the thrust washer and the shaft can rotate together to generate abnormal sound. When the speed changing gear shifts, the thrust washer rotates circumferentially on the spline shaft along with the contact of one gear end face, the inner hole of the thrust washer and the excircle of the spline on the shaft rotate relatively, the hardness of the surface of the spline shaft is far greater than that of the thrust washer, the inner hole of the thrust washer can be scraped, the condition that the inner hole of the thrust washer is abnormally abraded is caused, the abraded metal powder can cause secondary abrasion of moving parts in the gearbox, and the service life of the gearbox is shortened.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a friction factor is little, long service life's a thrust gasket of shifting that manual transmission used.
In order to meet the requirement, the utility model discloses a thrust washer of shifting that manual transmission used, it is the annular plane slide bearing of circle that the center system has the round hole, plane slide bearing be in a surface sintering of steel sheet have the copper alloy layer, the surface suppression on the copper alloy layer has recessed oil pocket and/or oil groove, characterized by inwards stretches out at least one convex claw of card in the spline groove at the edge of round hole.
The oil holes are spherical pits.
The oil groove is a straight groove with an arc surface.
The oil groove is bordered by the convex claw.
The number of the convex claws is two, and the two convex claws are arranged oppositely.
According to the gear-shifting thrust washer for the manual transmission, the gear-shifting thrust washer is sleeved on the spline shaft when in use, and the convex claws are clamped in the spline grooves, so that the gear-shifting thrust washer and the splines on the shaft cannot generate relative circumferential rotation motion, abnormal noise and abnormal abrasion of the inner holes of the spline-shifting thrust washer are eliminated, and the service life of the manual transmission is prolonged. The oil holes and the oil grooves improve the lubricating performance between the friction pairs, and the process is very simple as long as the friction pairs are directly extruded during manufacturing.
Drawings
FIG. 1 is a front view of a shift thrust washer for a manual transmission;
FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1;
FIG. 3 is a state diagram of a shift thrust washer for a manual transmission.
In the figure: 1. a circular hole; 2. a steel plate; 3. a copper alloy layer; 4. oil holes; 5. an oil sump; 6. a spline groove; 7. a convex claw; 8. a shift thrust washer; 9. a spline shaft.
Detailed Description
The invention is further described with reference to the accompanying drawings and specific embodiments.
Fig. 1 and 2 are schematic structural views of a shifting thrust washer for a manual transmission. The plane sliding bearing is a circular ring plane sliding bearing with a circular hole 1 at the center, a copper alloy layer 3 is sintered on one surface of a steel plate 2, the alloy layer 3 adopts CuSn10Bi3 as an alloy material, a concave oil pocket 4 and an oil groove 5 are pressed on the surface of the copper alloy layer 3, the oil pocket 4 is a spherical pit, and the oil groove 5 is a straight groove with a cambered surface. Two convex claws 7 used for being clamped in the spline grooves 6 extend inwards from the edge of the round hole 1, the two convex claws 7 are oppositely arranged, and the oil grooves 5 are bordered by the convex claws 7.
In use, the shifting thrust washer 8 is slipped over the splined shaft 9 and the dogs 7 snap into the splined grooves 6 as shown in figure 3. Therefore, the gear-shifting thrust washer 8 and the spline shaft 9 cannot generate relative circumferential rotary motion, abnormal noise and abnormal abrasion of the spline to the inner hole of the gear-shifting thrust washer 8 are eliminated, and the service life of the manual transmission is prolonged.
Claims (5)
1. A shift thrust washer for manual speed variator is a circular plane slide bearing with central hole, which is made up by sintering copper alloy layer on one surface of steel plate and pressing concave oil hole and/or oil groove on the surface of copper alloy layer, and features that at least one convex claw is extended inward from the edge of circular hole and clamped in spline groove.
2. The shifting thrust washer for manual transmission of claim 1 wherein said oil pockets are spherical dimples.
3. The shifting thrust washer for the manual transmission according to claim 1, wherein the oil groove is a straight groove with a cambered surface.
4. A gear shifting thrust washer for a manual transmission according to claim 1 wherein said oil groove borders said lug.
