Model utility content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, provides the double-clutch automatic gearbox shifting fork assembly that a kind of rigidity of shifting gears is high.
In order to realize above object, a kind of double-clutch automatic gearbox shifting fork assembly that the utility model provides, at least comprise three pull-fork assemblies, each described pull-fork assembly comprises shift fork and yoke bracket again respectively, described shift fork is connected with described yoke bracket by connecting plate, and the working surface of described shift fork and the material cross direction of described shift fork are arranged vertically.By being designed to by the working surface of shift fork be arranged vertically with the material cross direction of shift fork, like this, the Impact direction of shift fork is consistent with the material cross direction of shift fork, thus greatly increases the gear shift rigidity of shift fork.
In such scheme, described shift fork is dull and stereotyped bent part, is respectively equipped with the clamping boss matched with speed changer inter-sync cover inside the two ends of described shift fork.
In such scheme, the position of the corresponding described clamping boss in described shift fork two ends is respectively equipped with covered plastics layer, and the position of the correspondence described clamping boss bi-side of described covered plastics layer is described working surface.By adding covered plastics layer on the surface of clamping boss, not only increase gear shift wear resistance like this, but also reduce gear shift noise.
In such scheme, described yoke bracket is provided with the inductive component matched with gear inductor in speed changer.The inductive component added matches with gear inductor in speed changer, can be speed changer and provides shift fork gear information exactly.
In such scheme, described inductive component comprises magnet and magnet mounting bracket, and described magnet is arranged on described yoke bracket by described magnet mounting bracket.
In such scheme, the two ends of described yoke bracket are respectively equipped with linear bearing.The linear bearing added can reduce gearshift slip resistance widely.
The beneficial effect that the technological scheme that the utility model provides is brought is:
1, by being designed to by the working surface of shift fork be arranged vertically with the material cross direction of shift fork, like this, the Impact direction of shift fork is consistent with the material cross direction of shift fork, thus greatly increases the gear shift rigidity of shift fork;
2, by adding covered plastics layer on the surface of clamping boss, not only increase gear shift wear resistance like this, but also reduce gear shift noise;
3, the inductive component added matches with gear inductor in speed changer, can be speed changer and provides shift fork gear information exactly;
4, the linear bearing added can reduce gearshift slip resistance widely.
The utility model is compared with the prior art, and fully its superiority of display is: gear shift rigidity is high, and gear shift noise is little, and the good and slip resistance of shifting gears of wear resistance is little.
