The connecting structure for an automobile gear shifting fork and a fork shaft comprises a shifting fork and a fork shaft, the shifting fork comprises a connecting portion and two fork claws which are integrally formed with the connecting portion, spaced and arranged symmetrically, a groove is disposed on the side of the fork shaft, a mounting groove is arranged on the connecting portion of the shifting fork, and the connecting portion of the shifting fork can be clamped onto the groove via the mounting groove on the connecting portion. The groove is arranged on the side of the fork shaft, the mounting groove is disposed on the connecting portion of the shifting fork, the connecting portion of the shifting fork can be clamped onto the groove via the mounting groove, so that the shifting fork can be mounted on the fork shaft conveniently, and the shifting fork mounted on the fork shaft is accurate in positioning, high in strength and not easy to deform.
Description
Technical field
The utility model belongs to the vehicle transmission technical field, relates to a kind of selector fork, particularly relates to the connection structure of a kind of automobile gear shift shift fork and fork shaft.
Background technology
Selector fork is one of important component in the change-speed box, and during work, selector fork is to be the cantilever beam of fulcrum with the fork shaft, and traditional shift fork and fork shaft generally all use the alloy steel to forge, and its weight is bigger, poor-performing.
According to this above-mentioned situation, present shift fork and fork shaft great majority are made by the cold isostatic compaction to sheet material, because the cost that sheet material is made is low, the profiled member that causes making shift fork and fork shaft by sheet material is used widely, mode by welding after shift fork and fork shaft moulding is connected both, since the shift fork thinner thickness, shift fork and fork shaft welding back vent pawl easy deformation; Be out of shape with fork shaft welding back vent pawl for fear of shift fork, after increasing the plate of shift fork gradually, and increased the overall weight of change-speed box behind the increase plate to a certain extent, the essential power that will be bigger of the weight general trend of events, so not only user's operation inconvenience to some extent when gearshift, simultaneously also can strengthen the loss of automotive oil, thereby cause waste; And the shift fork relative position that is welded on fork shaft difficulty comparatively when being installed in the location, can waste a lot of human and material resources.
The utility model content
The purpose of this utility model is at existing deficiency, and a kind of not yielding, accurate positioning, the convenient automobile gear shift shift fork of installing and the connection structure of fork shaft are provided.
The purpose of this utility model can realize by following technical proposal: the connection structure of a kind of automobile gear shift shift fork and fork shaft, comprise shift fork and fork shaft, described shift fork comprises connecting portion and is separated by and symmetrically arranged fork pawl with integrated two of connecting portion, it is characterized in that, have groove on the described fork shaft sidepiece, the connecting portion of described shift fork has mounting groove, and the connecting portion of above-mentioned shift fork can be connected on the above-mentioned groove by the mounting groove on it.
The connection structure of this automobile gear shift shift fork and fork shaft, mainly by shift fork and fork shaft, shift fork and fork shaft used the mode of clamping to link together, and made things convenient for shift fork to be installed on the fork shaft, made fork be installed in accurate positioning on the fork shaft, intensity is big.
In the connection structure of above-mentioned automobile gear shift shift fork and fork shaft, described fork shaft is strip.The purpose of She Zhiing is like this, saves the installing space of fork shaft.
In the connection structure of above-mentioned automobile gear shift shift fork and fork shaft, the access section of described shift fork and fork shaft is welded to connect.Further improve the mechanical strength of fork and fork shaft junction.
In the connection structure of above-mentioned automobile gear shift shift fork and fork shaft, described shift fork and fork shaft are made by plate stamping respectively.Make shift fork and fork shaft in change-speed box, the miniaturization that occupation space is littler, help change-speed box.
Compared with prior art, the connection structure of this automobile gear shift shift fork and fork shaft, on the fork shaft sidepiece, have groove, the connecting portion of shift fork has mounting groove, the connecting portion of shift fork can be connected on the groove by mounting groove, make things convenient for shift fork to be installed on the fork shaft, make fork be installed in accurate positioning on the fork shaft, intensity is big, shift fork and fork shaft are made by sheet material respectively, it is little that shift fork and fork shaft are taken up room in change-speed box, helps the miniaturization of change-speed box, and the junction of shift fork and fork shaft is welded to connect, both junctions make the fork pawl not yielding away from the fork pawl position of shift fork.

The specific embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Automobile is in the process of travelling, and regular meeting carries out gear shift operation according to road conditions are different, and automobile gear shift is finished by change-speed box, and the gearshift on the change-speed box realizes by synchro, selector fork and gearshift.Transmission assembly when assembling gearshift is stirred shift fork and is referred to, selector fork fork pawl is stirred synchronizer gear sleeve, makes it to realize the shift of transmission function with the gear engagement indented joint.
As Fig. 1, Fig. 2, shown in Figure 3, the connection structure of this automobile gear shift shift fork and fork shaft, mainly form by shift fork 1 and fork shaft 2, shift fork 1 and fork shaft 2 are made with sheet material respectively, shift fork 1 has connecting portion 1a and is separated by and symmetrically arranged fork pawl 1b with integrated two of connecting portion 1a, and the connecting portion 1a of shift fork 1 has mounting groove 1c, and fork shaft 2 is strip, have groove 2a on fork shaft 2 sidepieces, the connecting portion 1a of shift fork 1 can be connected on the groove 2a of fork shaft 2 by the mounting groove 1c on it.For the mechanical strength of the junction of improving shift fork 1 and fork shaft 2, be connected in the access section welding of shift fork 1 with fork shaft 2.
Specific embodiment described herein only is that the utility model spirit is made casehistory.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
