Abstract
The utility model discloses a three fourth speeds in roll formula car shift fork of shifting, right shifting fork arm (2) and left fork arm (3) including integrated into one piece, it drives the fender to form semi -circular shifting fork between right shifting fork arm (2) and left fork arm (3), the shift fork belonged to planar declutch shift shaft mounting hole (1) about left side right shifting fork arm binding site was equipped with the perpendicular to, left side fork arm (3) and right fork arm (2) front end inboard are equipped with roller assembly (5) respectively, the shift fork leaves the fender bottom and is equipped with crescent friction disc (4). The utility model discloses a friction sleeve is established to shift fork pot head before fork arm, sets up the friction disc in division fender bottom, can effectively improve the life of shift fork, the utility model discloses at friction sleeve and friction disc chrome -faced, the ability of resistance to wearing of shift fork has further been increased.
Description
Technical field
This utility model relates to Automatic transmission technical field, relates to the shift fork reducing shift fork hole with the abrasion of the tooth collar, keeps off selector fork particularly to a kind of roller automobile three or four.
Background technology
Shift fork is belonging to the part in auto parts and components, mainly promoting balladeur train, balladeur train has an annular groove shift fork just ride in this annular groove, when driver promotes gear lever, gear lever drives shift fork axle, shift fork axle drives shift fork, and shift fork promotes gear again thus reaches gearshift.Existing shift fork easily rubs with gear, and the abrasion ratio of shift fork is more serious, and the bulk strength ratio of shift fork is relatively low, and the situation of fracture often occurs, and safety coefficient ratio is relatively low, shortens the service life of shift fork, greatly reduces the reliability of automobile starter work.
Summary of the invention
In view of this, this utility model provides a kind of roller automobile three or four and keeps off selector fork.
A kind of roller automobile three or four keeps off selector fork, including integrated right shift fork arm and left shift fork arm, form semicircle shift fork between described right shift fork arm and left shift fork arm and open gear, described left and right shift fork arm binding site is provided with the shift fork axle installing hole being perpendicular to shift fork place, left and right plane, described left shift fork arm and right shift fork arm leading inside are respectively equipped with roller assembly, and described shift fork is opened and is provided with crescent friction plate bottom gear.
Further, described roller assembly includes that roller shaft and roller, described roller shaft one end are arranged on inside shift fork arm, and the other end is connected with roller, and described roller can rotate around roller shaft, and described roller is metal material, and its surface is coated with the chromium that 50-100 micron is thick.
Further, shift fork leaves and is provided with breach bottom gear, and described friction plate is inlayed or is fixed in this breach by securing member, and described Friction Disk Surface is coated with the chromium that 30-50 micron is thick.
The beneficial effects of the utility model are:
Shift fork of the present utility model arranges roller assembly in shift fork arm front end, friction tile is set bottom gear opening, is relative rolling between roller with release bearing during use, shift fork abrasion is greatly reduced, this utility model, in roller and friction pad chrome-faced, can extend its service life further.Roller assembly of the present utility model and the most dismountable setting of friction pad, replace corresponding component, it is not necessary to change shift fork body after abrasion.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is described in further detail, wherein:
Fig. 1 is that this utility model three or four keeps off selector fork structure chart；
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, 2, a kind of roller automobile three or four keeps off selector fork, including integrated right shift fork arm 2 and left shift fork arm 3, form semicircle shift fork between described right shift fork arm 2 and left shift fork arm 3 and open gear, described left and right shift fork arm binding site is provided with the shift fork axle installing hole 1 being perpendicular to shift fork place, left and right plane, described left shift fork arm 3 and right shift fork arm 2 leading inside are respectively equipped with roller assembly 5, and described shift fork is opened and is provided with crescent friction plate 4 bottom gear；
In the present embodiment, described roller assembly 5 includes that roller shaft and roller, described roller shaft one end are arranged on inside shift fork arm, and the other end is connected with roller, and described roller can rotate around roller shaft, and described roller is metal material, and its surface is coated with the chromium that 50-100 micron is thick；
In the present embodiment, shift fork leaves and is provided with breach bottom gear, and described friction plate 4 is inlayed or is fixed in this breach by securing member, and described friction plate 4 surface is coated with the chromium that 30-50 micron is thick.The present embodiment is additionally provided with the shift fork axle fastener hole 6 that communicate vertical with shift fork axle installing hole 1.
Shift fork of the present utility model is at the sheathed friction sleeve in shift fork arm front end, friction plate is set bottom gear opening, strengthens the friction resistant ability at shift fork friction position, improve its service life, this utility model, in friction sleeve and Friction Disk Surface chromium plating, further increases the antiwear property of shift fork.Friction sleeve of the present utility model and the most dismountable setting of friction plate, replace corresponding component, it is not necessary to change shift fork body after abrasion.
Finally illustrate is, above example is only in order to illustrate the technical solution of the utility model and unrestricted, although this utility model being described by referring to preferred embodiment of the present utility model, but it will be understood by those within the art that, in the form and details it can be made various change, the spirit and scope of the present utility model limited without departing from appended claims.
