Description
Technical field
The present invention relates to a kind of left shifting fork structure of transmission countershaft, belong to vehicle accessory.
Background technology
The shifting fork structure of existing transmission countershaft is made from cast steel material, and shift fork stirs the allocating slot in shift fork by poke rod
When, the stress fork face contacted is vulnerable to larger abrasion, and different wear surfaces can be produced because of unbalance stress, therefore
Unreasonable structure be present, stir the defects of dumb smooth.The shifting fork structure of other existing transmission countershaft be divided into again left shift fork with
Right shift fork, because the direction of shift fork is different, thus structure is also variant, and at present because structure is almost identical, cause in stress side
In the case of difference, easily cause the difference of stress size, reduce service life.
The content of the invention
It is an object of the invention to overcome the shortcomings of the prior art, and offer is a kind of rational in infrastructure, uses operation side
Just, shift fork is flexibly smooth, and abrasion is small, the left shifting fork structure of the transmission countershaft of service life length.
The purpose of the present invention is completed by following technical solution, a kind of left shifting fork structure of transmission countershaft, and it leads
To be made into integration by the shift fork body for the shift fork axle and sheet for being provided with axially extending bore, the front portion of shift fork body offers semicircle dial
Groove, for the notch of the semicircle allocating slot towards left side, the notch front and rear side edge of semicircle allocating slot is respectively arranged with the semicircle of projection
Ring shift fork plane, and applied in shift fork plane and be formed with one layer of wear-resistant coating；Described shift fork body bottom is mutually connected in shift fork axle
Left side section, the right side section of shift fork axle is higher by shift fork body at least half, and forms left shifting fork structure；Respectively use the side of shift fork body two
Thicken the both sides that inclined-plane rib connects the shift fork axle；Axially extending bore axle is provided perpendicular on the left side wall of the shift fork axle
The locating dowel at center.
As preferred：Two outside hypotenuses of the shift fork body semicircular ring phase raised with the perisporium and notch of shift fork axle respectively
Cut connection, and the outer bulge loop to connect on the perisporium of the shift fork axle formed with a circle with the outside hypotenuse of shift fork body two；It is described fixed
It with the axis center of axially extending bore and the notch line of centres is in 90 ° that the arrangement of position post, which is, and it is small to be additionally provided with end in the locating dowel
Projection.
The invention belongs to improvements over the prior art, it has rational in infrastructure, and use is easy to operate, and gearshift is smooth, abrasion
It is small, the features such as service life is long.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 Fig. 1 A direction views.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail：Fig. 1, shown in 2, a kind of transmission countershaft of the present invention
Left shifting fork structure, it is mainly made into integration by the shift fork body 3 of the shift fork axle 2 and sheet that are provided with axially extending bore 1, shift fork body
3 front portion offers semicircle allocating slot 4, and the notch of the semicircle allocating slot 4 is towards left side, before and after the notch of semicircle allocating slot 4
Edge is respectively arranged with the semicircular ring shift fork plane 5 of projection, and is applied in shift fork plane 5 and be formed with one layer of wear-resistant coating；Described
The bottom of shift fork body 3 is mutually connected in the left side section of shift fork axle 2, and the right side section 6 of shift fork axle 2 is higher by least half of shift fork body 3, and forms
Left shifting fork structure；Described 3 liang of sides of shift fork body respectively connect the both sides of the shift fork axle 2 with thickening inclined-plane rib 7, serve reinforcement
The effect of muscle, further enhance bonding strength between the two；Axle is provided perpendicular on the left side wall of the shift fork axle 2
To the locating dowel 8 of the axis center of through hole 1.
Shown in figure, two outside hypotenuses 9 of the shift fork body 3 semicircle raised with the perisporium and notch of shift fork axle 2 respectively
The tangent connection of ring, and the outer bulge loop to connect on the perisporium of the shift fork axle 2 formed with a circle with the outside hypotenuse 9 of shift fork body two
10；It with the axis center of axially extending bore 1 and the notch line of centres is in 90 ° that the arrangement of the locating dowel 8, which is, in the locating dowel 8 also
It is provided with end small convex pillar 11.
It is of the present invention left and right be by being defined shown in Fig. 1, the inside and outside left side using shown in Fig. 2 be it is interior, the right side be it is outer, just
It is good with it is corresponding shown in Fig. 1.
The present invention is the improvement to prior art, therefore, those skilled in the art on the basis of present invention is understood,
Using common sense and known technology that itself is grasped, the present invention can be advantageously carried out.
