Abstract
The utility model discloses a vehicle shift fork, its technical scheme main points are including shift fork body, spliced pole, the spliced pole is integrative to be set up in shift fork body one end, the shift fork body other end is equipped with two and connects the fork, the shift fork body is close to spliced pole one side and is equipped with the kink, the kink is the echelonment, this first strengthening rib that has the slope between kink and the shift fork body, be equipped with the second strengthening rib of slope between spliced pole and the kink.
Description
Technical field
The utility model relates to a kind of vehicle component and manufactures field, and more particularly, it relates to a kind of vehicle shift fork.
Background technique
Vehicle shift fork is used to promote transmission gear, changing the instrument of gear position, changing tooth ratio, to reach the object of speed change by gear being changed position.The gear of speed changer is all load on main shaft and countershaft, promotes them and advances or retreat, just can change tooth ratio by shift fork.Thus the structure of vehicle shift fork and the effect of speed changer have very important relation.
And the active force produced when shifting gears when running all can by vehicle shift fork, and shift fork attachment post is comparatively weak with shift fork body joint, thus when stressed excessive time easily produce and bend or rupture.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of attachment post and the high vehicle shift fork of shift fork body joint structural strength.
For achieving the above object, the utility model provides following technological scheme: a kind of vehicle shift fork, comprise shift fork body, attachment post, described attachment post is wholely set in shift fork body one end, the described shift fork body the other end is provided with two cleviss, and described shift fork body is provided with kink near attachment post side, and described kink is stepped, between described kink and shift fork body, this has the first stiffening rib of inclination, is provided with the second stiffening rib of inclination between described attachment post and kink.
Preferably, described first stiffening rib is identical with the second stiffening rib inclination.
Preferably, described attachment post side is provided with handle connecting head, and described handle connecting head is provided with contiguous block.
Preferably, the inclination of described first stiffening rib and shift fork body is 50 degree.
Preferably, the inclination of described kink side and shift fork body is 72.7 degree.
Compared with prior art, the beneficial effects of the utility model are: owing to being provided with stair-stepping kink between shift fork body and attachment post, and the kink produced has good elasticity, and make between shift fork body and attachment post, to produce 2 road angles, and angle is respectively equipped with the first stiffening rib and the second stiffening rib, thus make through active force can together segmentation by the first stiffening rib and the second stiffening rib, what make that the superfluous active force of part can be temporary transient exists on kink, thus avoid larger power and directly pass through and produce fracture, thus effectively raise the life-span of use, and at the middle part of kink, owing to there is no the support of stiffening rib, thus make kink effectively carry out vibration by a small margin by elastic reaction, thus effectively can consume the superfluous active force of gathering, effectively decrease active force to have an impact to shift fork body, improve working life.
Accompanying drawing explanation
Fig. 1 is the stereogram of the utility model vehicle shift fork embodiment;
Fig. 2 is the plan view of the utility model vehicle shift fork embodiment;
Fig. 3 is the side view of the utility model vehicle shift fork embodiment.
Reference character: 1, shift fork body; 2, attachment post; 3, clevis; 4, kink; 41, the first stiffening rib; 42, the second stiffening rib; 5, handle connecting head; 51, contiguous block.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model vehicle shift fork embodiment is described further.
A kind of vehicle shift fork, comprise shift fork body 1, attachment post 2, described attachment post 2 is wholely set in shift fork body 1 one end, described shift fork body 1 the other end is provided with two cleviss 3, described shift fork body 1 is provided with kink 4 near attachment post 2 side, described kink 4 is stepped, between described kink 4 and shift fork body 1, this has the first stiffening rib 41 of inclination, the second stiffening rib 42 of inclination is provided with between described attachment post 2 and kink 4, owing to being provided with stair-stepping kink 4 between shift fork body 1 and attachment post 2, and the kink 4 produced has good elasticity, and make between shift fork body 1 and attachment post 2, to produce 2 road angles, and angle is respectively equipped with the first stiffening rib 41 and the second stiffening rib 42, thus make through active force can together segmentation by the first stiffening rib 41 and the second stiffening rib 42, what make that the superfluous active force of part can be temporary transient exists on kink 4, thus avoid larger power and directly pass through and produce fracture, thus effectively raise the life-span of use, and at the middle part of kink 4, owing to there is no the support of stiffening rib, thus make kink 4 effectively carry out vibration by a small margin by elastic reaction, thus effectively can consume the superfluous active force of gathering, effectively decrease active force to have an impact to shift fork body 1, improve working life.
Described first stiffening rib 41 is identical with the second stiffening rib 42 inclination, makes be entered smoothly on the second stiffening rib 42 by the power of the first stiffening rib 41, avoids producing deviation during force transmission, causes stressed generation bending distortion in the middle part of kink 4.
Described attachment post 2 side is provided with handle connecting head 5, and described handle connecting head 5 is provided with contiguous block 51, thus outside handle capable of being is connected with contiguous block 51 easily, carries out transmission easily.
Described first stiffening rib 41 is 50 degree with the inclination of shift fork body 1, because shift fork body 1 length is greater than the length of attachment post 2, thus the relative attachment post 2 of clevis 3 is distant, thus when the first stiffening rib 41 inclination is 50 degree, from the connection area making the first stiffening rib 41 and the connection area of shift fork body 1 be greater than the first stiffening rib 41 and attachment post 2, thus active force is made more comprehensively, to be effectively transferred on shift fork body 1.
The inclination of described kink 4 side and shift fork body 1 is 72.7 degree, because kink 4 also has the inclination of 72.7, thus active force can be delivered on shift fork body 1 more smoothly through kink 4.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
