Description
Technical field
The utility model belongs to design of automobile transmission field, is specifically related to a kind of front and back point thimble shape speed changer shelves shift fork switching mechanism.
Background technique
The domestic armstrong's patent speed changer containing overdirve gear at present, needs to arrange changement in selector gear when changing overdirve gear, with realize gear shifting handle on the gear order indicated, harmonious with actual shift gear.The current domestic over drive transmision overdirve gear changement form of commutation plectrum that adopts realizes more, but this kind of mechanism form is mainly suitable for dividing hull shape formula up and down, divides thimble shape over drive transmision more difficult use for front and back.The utility model patent provides a kind of mechanism that can be used for realizing front and back point thimble type over drive transmision overdirve gear commutation.
Model utility content
Technical problem to be solved in the utility model is: provide a kind of front and back point thimble shape transmission selector fork switching mechanism, before and after realizing, divide the commutation of thimble type over drive transmision overdirve gear.
In order to solve above technical problem, the technological scheme that the utility model provides is as follows:
Point thimble shape transmission selector fork switching mechanism before and after a kind of, it is characterized in that, this mechanism forms primarily of selector fork 1, pivot 2 and insert 6;
Top bulb 7 is provided with above described selector fork 1, and above side, selector fork 1 two ends, have two symmetrical fulcrum holes, described pivot 2 is containing bigger diameter end and miner diameter end, wherein, the miner diameter end of pivot 2 is connected by fulcrum hole and selector fork 1, and bigger diameter end and the case of transmission of pivot 2 are connected;
One end of described insert 6 is cylindrical structure, and insert 6 is connected by the pilot hole below this cylindrical structure and side, selector fork 1 two ends.
Further, this mechanism also comprises locking plate 4 and bolt 5, and the circumferential surface of described pivot 2 bigger diameter end has semi-circular groove, and this semi-circular groove is inserted in one end of locking plate 4, and the other end is arranged on case of transmission by bolt 5.
Further, this mechanism also comprises O RunddichtringO 3, and the circumferential surface of described pivot 2 bigger diameter end also has annular groove, and described O RunddichtringO 3 is arranged in this annular groove.
The beneficial effects of the utility model are: point thimble type over drive transmision before and after this selector fork switching mechanism is applicable to, structure is simple, and applicability is strong.

Embodiment
The technical solution of the utility model is illustrated further below in conjunction with Figure of description:
As depicted in figs. 1 and 2, the utility model discloses a kind of front and back point thimble shape transmission selector fork switching mechanism, this mechanism forms primarily of selector fork 1, pivot 2 and insert 6, and wherein pivot 2 and insert 6 respectively have a pair, is arranged on selector fork 1 both sides respectively.
Top bulb 7 is provided with above selector fork 1, two symmetrical fulcrum holes are had above side, selector fork 1 two ends, pivot 2 is containing bigger diameter end and miner diameter end, wherein, the miner diameter end of pivot 2 is connected by the fulcrum hole and selector fork 1 inserting selector fork 1, pivot 2 bigger diameter end circumferential surface on have semi-circular groove, this semi-circular groove is inserted in one end of locking plate 4, the other end is connected with case of transmission by bolt 5, and then realizes being connected of pivot 2 and case of transmission.Pivot 2 bigger diameter end circumferential surface on also have an annular groove, O RunddichtringO 3 be arranged in this annular groove for realize sealing.
One end of insert 6 is cylindrical structure, has two symmetrical pilot holes below side, selector fork 1 two ends, and insert 6 is by inserting cylindrical structure in this pilot hole to realize being connected.The other end of insert 6 is plane, coordinates with synchronizer.
During gearshift, be applied on the top bulb 7 of selector fork 1 effectively, promote top bulb 7 to a lateral movement, selector fork 1 is 2 rotations pivotally, the opposite direction motion that selector fork 1 drives insert 6 to move to top bulb 7, and then drive synchronizer, realize upset gearshift function.
