Description
Technical field
The utility model relates to a kind of selector fork, the selector fork especially in manual transmission, belongs to auto parts and components equipment technical field.
Background technique
What use along with automobile popularizes, and the requirement of user to automotive performance is more and more higher.Selector fork in tradition passenger car manual transmission is by the restriction of self structure, a selector fork can only be realized at axial same position place and use a synchronizer, thus increase the axial distance of speed changer, become the limiting factor that transmission gear gear space is arranged.
Model utility content
The utility model object is to provide a kind of selector fork, can realize two selector forks at axial same position and use two synchronizers, thus make the layout of the shift gear of manual transmission and axle more flexible, solve Problems existing in background technique.
The technical solution of the utility model is:
A kind of selector fork, comprise selector fork body, described selector fork body both sides are respectively equipped with shift fork a and shift fork b, the all curved structure of shift fork a and shift fork b, arc opening is towards the same side, selector fork body is also provided with fitting hole, positioning pin hole a and positioning pin hole b, guide block and lightening grooves, positioning pin hole a and positioning pin hole b and fitting hole are arranged vertically, positioning pin hole a and positioning pin hole b dead in line, the axis of positioning pin hole a and positioning pin hole b and the axes intersect of fitting hole, guide block is located at above fitting hole.
Described shift fork a and shift fork b semicircular in shape structure, the axes normal of its central axis and fitting hole is arranged.
Described shift fork a, shift fork b and tooth overlap gear ring and are connected.
The U-shaped structure of described guide block.
Described lightening grooves concave architecture triangular in shape.
Adopting the utility model, after fitting hole and positioning pin hole a, positioning pin hole b fix, by stirring guide block, selector fork body being moved axially, thus drive two teeth cover gear rings to realize gearshift function.
The beneficial effects of the utility model are: can realize two selector forks at axial same position and use two synchronizers, thus the object that the gear that can reach adjacent two gears is arranged apart, the space of gear and axle is arranged more flexible, structure is simple, easily manufactured and cost of production is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
In figure: shift fork a1-1, shift fork b1-2, fitting hole 2, positioning pin hole a3-1, positioning pin hole b3-2, guide block 4, lightening grooves 5.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, a kind of selector fork, comprise selector fork body, described selector fork body both sides are respectively equipped with shift fork a1-1 and shift fork b1-2, the all curved structure of shift fork a1-1 and shift fork b1-2, arc opening is towards the same side, selector fork body is also provided with fitting hole 2, positioning pin hole a3-1 and positioning pin hole b3-2, guide block 4 and lightening grooves 5, positioning pin hole a3-1 and positioning pin hole b3-2 and fitting hole 2 are arranged vertically, positioning pin hole a3-1 and positioning pin hole b3-2 dead in line, the axis of positioning pin hole a3-1 and positioning pin hole b3-2 and the axes intersect of fitting hole 2, guide block 4 is located at above fitting hole 2.
In the present embodiment, selector fork body is that cast inblock forms, shift fork a1-1 and shift fork b1-2 semicircular in shape structure, and the axes normal of its central axis and fitting hole 2 is arranged, shift fork a1-1, shift fork b1-2 and tooth overlap gear ring and be connected.The U-shaped structure of guide block 4, lightening grooves 5 concave architecture triangular in shape.
Guide block 4 jointly can be cast with selector fork body and form, and also can be connected by welding and selector fork body.An independently part can also be become, realize direct or indirect drive selector fork body and move axially.
Lightening grooves 5 is under the prerequisite ensureing wall thickness, and can increase several lightening grooves as required, lightening grooves 5 can be the groove structure of any shape.
After fitting hole 2 and positioning pin hole a3-1, positioning pin hole b3-2 fix, by stirring guide block 4, selector fork body is moved axially, thus drive two teeth cover gear rings to realize gearshift function.
