Description
Technical field
The utility model belongs to mechanical part technical field, is specifically related to a kind of shift fork.
Background technique
Shift fork, for the gear plectrum of two occlusions being come in operating mechanism, again one of them gear that can slide on bearing is pushed on another one gear to obtain another speed, realize the position of the shifting slide gear changing operating mechanism, realizing speed change, is mechanical part conventional in mechanical mechanism.But existing shift fork, fork arm soundness is not good, easily ruptures, and axle sleeve is the ring body of sealing, is tightened on bearing, and when shift fork carrys out back rotation, the screw thread easily in wearing and tearing axle sleeve, shortens its working life.
Model utility content
The technical problem that the utility model solves overcomes existing shift fork, and fork arm soundness is not good, easily ruptures, and axle sleeve is the ring body of sealing, is tightened on bearing, when shift fork carrys out back rotation, the screw thread easily in wearing and tearing axle sleeve, shortens its problem in working life.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is:
A kind of shift fork, it is characterized in that: comprise axle sleeve and fork body, be connected by fork arm between described axle sleeve and fork body, described fork arm is provided with large end, small end, and width reduces from large end gradually to small end, the large end of described fork arm is positioned at fork side, the small end of described fork arm is positioned at axle sleeve side, the middle part of described fork arm both sides is equipped with a stiffening rib, described axle sleeve is also provided with breach, the axle sleeve of described breach both sides is equipped with fixing projection, is linked together by lock bolt between two fixing projections.
Aforesaid a kind of shift fork, is characterized in that: described stiffening rib is right-angled triangle, and the right angle side of described stiffening rib is close to the side of fork arm.
Aforesaid a kind of shift fork, is characterized in that: the width of described breach is 0.5-1cm.
Aforesaid a kind of shift fork, is characterized in that: the width of described breach is 0.8cm.
Aforesaid a kind of shift fork, is characterized in that: the inwall of described axle sleeve is provided with steel bushing in a circle boron carbide.
Aforesaid a kind of shift fork, is characterized in that: in described boron carbide, steel bushing is provided with gap, and described gap is identical with the width of breach.
The beneficial effects of the utility model are: shift fork of the present utility model; the middle part of fork arm both sides is equipped with a stiffening rib, improves the soundness of fork arm, axle sleeve is also provided with breach; the axle sleeve of breach both sides is equipped with fixing projection; linked together by lock bolt between two fixing projections, can when axle sleeve carry out back rotation, the screw thread in protection axle sleeve; extend the working life of shift fork; structure is simple, easy to use, has a good application prospect.
Accompanying drawing explanation
Fig. 1 is the plan view of shift fork of the present utility model.
Fig. 2 is the side view of shift fork of the present utility model.
The implication marked in accompanying drawing is as follows:
1: axle sleeve; 2: fork body; 3: fork arm; 4: stiffening rib; 5: breach; 6: fixing projection; 7: lock bolt; 8: steel bushing in boron carbide.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figures 1 and 2, a kind of shift fork, comprise axle sleeve 1 and fork body 2, be connected by fork arm 3 between axle sleeve 1 and fork body 2, fork arm 3 is provided with large end, small end, and width reduces from large end gradually to small end, the large end of fork arm 3 is positioned at fork side, the small end of fork arm 3 is positioned at axle sleeve side, the middle part of fork arm 3 both sides is equipped with a stiffening rib 4, stiffening rib 4 is right-angled triangle, the right angle side of stiffening rib 4 is close to the side of fork arm 3, the soundness of fork arm can be improved, axle sleeve 1 is also provided with breach 5, the axle sleeve 1 of breach 5 both sides is equipped with fixing projection 6, linked together by lock bolt 7 between two fixing projections 6, the width of breach 5 is 0.5-1cm, preferred 0.8cm, can when axle sleeve carrys out back rotation, the headspace of breach 5, screw thread in protection axle sleeve, extend the working life of shift fork, and, the inwall of axle sleeve 1 is provided with steel bushing 8 in a circle boron carbide, in boron carbide, steel bushing 8 slows down the wearing and tearing of axle sleeve 1 further, and steel bushing 8 is provided with gap in boron carbide, gap is identical with the width of breach 5, reserved axle sleeve carrys out back rotation time space.
In sum, shift fork of the present utility model, the middle part of fork arm both sides is equipped with a stiffening rib; improve the soundness of fork arm; axle sleeve is also provided with breach, the axle sleeve of breach both sides is equipped with fixing projection, linked together by lock bolt between two fixing projections; can when axle sleeve carrys out back rotation; screw thread in protection axle sleeve, extend the working life of shift fork, structure is simple; easy to use, have a good application prospect.
More than show and describe basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
