Abstract
The utility model discloses a kind of automotive gear-shifting fork, being intended to provide a kind of rubs little with gear, stressed good, lightweight, and with shift fork axle, firmly automotive gear-shifting fork is installed, its technological scheme mainly arranges ball on the face of shift fork and Gear Contact, the friction produced during its relative movement is rubbed by East China and becomes rolling friction to reduce the stressed of shift fork, offer through hole at shift fork and shift fork axle joint simultaneously, through hole and shift fork are soldering point with the tactile limit that is coupling, add shift fork and shift fork axle bonding area, ensure that shift fork and shift fork axle install more firm stable, face offers through hole with fork, be used for alleviating the overall weight of shift fork.
Description
Technical field
The utility model relates to a kind of automobile shift fork, and mainly a kind of being used for controls the selector fork of automobile gear shift.
Background technique
Selector fork is applied in the gearshift of gearbox, declutch shift shaft joint is enclosed within gear shift fork shaft, pressing fork rack is then clipped in the groove of duplex change wheel, when needs speed change, handle speed change lever, conversion operating mechanism just drives shift fork slippage in gearbox together with gear shift fork shaft by the pilot slot of shift fork head, and pressing fork rack is stirred duplex change wheel and to be slided on spline change gear, thus change speed.
The shift fork of prior art, pressing fork rack directly contacts with gear circular groove, sliding friction, during pinion rotation, the friction that shift fork is subject to is very large, and long-time use can be subject to larger wearing and tearing, reduce the working life of shift fork, meanwhile, fork drawing material mostly is cast steel, and raw material use more, shift fork overall weight is heavier, add shift fork almost vertical with declutch shift shaft, automobile shift hunting works, and the connection of shift fork and declutch shift shaft is difficult to ensure firm and stable connection.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of rubs little with gear, stressed good, lightweight, and installs firmly automotive gear-shifting fork with shift fork axle.
For achieving the above object, the utility model provides following technological scheme: a kind of automotive gear-shifting fork, comprise declutch shift shaft joint, fork face and crotch, described fork face is axisymmetric shape, fork face is fixedly connected with joint, face is arranged with crotch with fork, described crotch is provided with contacting part, described contacting part is provided with ball recess, described ball recess opening direction is towards the symmetry axis in fork face, described ball recess internal fixtion is embedded with ball, described ball can in ball recess inner rotation, the opposite side end face that described joint connects relative to fork face is provided with groove, described fork face is provided with through hole, described through hole is waist through hole, described waist through hole bends towards crotch dorsad.
By adopting technique scheme, contacting part arranges ball recess, ball is inlayed in ball recess, during the motion of shift fork driven gear, ball and gear ring connected in star connecting part, avoid contacting part surface directly and the contact of gear ring connected in star, sliding friction is become rolling friction, decrease the frictional force suffered by shift fork contacting part, thus alleviate the frayed degree of shift fork contacting part, effectively improve the working life of shift fork, joint is provided with groove, when shift fork joint welds with declutch shift shaft, groove four limit can be welded with declutch shift shaft, add the bonding area of shift fork and declutch shift shaft, thus ensure that shift fork and declutch shift shaft more firm, stable connection, through hole is offered in face with fork, alleviate shift fork overall weight, when making automobile gear shift, the required power being applied to shift fork is smaller, simultaneously, via design is waist through hole, and crotch bending dorsad, such design, both simply easy to process, alleviate again the overall weight of shift fork, also assures that shift fork has certain rigidity simultaneously, can not rupture easily.
The utility model is set to further: described ball recess is evenly distributed on contacting part, and described ball is mounted in ball recess, and the ball recess degree of depth is greater than ball bearing radius and is less than ball diameter.
By adopting technique scheme, described ball recess is evenly distributed on contacting part, described ball is mounted in ball recess, the ball recess degree of depth is greater than ball bearing radius and is less than ball diameter, more solid and reliable when ensure that ball rolls in ball recess, can not drop out from ball recess, improve shift fork overall work reliability.
The utility model is set to further: described crotch is arc.
By adopting technique scheme, crotch is designed to arc, shift fork crotch can be made to contact with gear ring connected in star tightr, coordinate better, thus improve the service behaviour of shift fork.
The utility model is set to further: described shift fork aluminum alloy material makes.
By adopting technique scheme, shift fork adopts aluminum alloy replacement cast steel to make, and aluminum alloy is compared with cast steel, and wear resistance is good, and material is light, makes shift fork with aluminum alloy, and overall weight is light, controls applying power required when shift fork moves little.
Accompanying drawing explanation
Fig. 1 is a kind of automotive gear-shifting fork structural drawing of the utility model.
In accompanying drawing, 1. joint; 11. grooves; 2. pitch face; 21. through holes; 3. crotch; 4. contacting part; 41. ball recess; 42. balls.
Embodiment
A kind of automotive gear-shifting fork, comprise joint 1, fork face 2, crotch 3, fork face 2 is welded and fixed is connected with crotch 3, joint 1 respectively, and joint 1 is used for being enclosed within declutch shift shaft and welds with declutch shift shaft.
Crotch 3 is fixed with contacting part 4, described contacting part 4 and the manufacture of crotch 3 Integral design, contacting part is provided with ball recess 41, ball 42 is inlaid with in ball recess, ball recess 41 degree of depth is greater than ball 42 radius and is less than ball 42 diameter, ball 42 can not drop when rolling in ball recess 41, ball recess 41 is evenly distributed on contacting part 4, when under the drive of shift fork at declutch shift shaft during the motion of control gear axle, contacting part 4 does not directly contact with gear ring connected in star, but contacted with annular groove by ball 42, during pinion rotation, ball 42 rolls, such setting makes contacting part 4 rub with the slip of annular groove and becomes rolling friction, reduce the frictional force suffered by contacting part 4, thus alleviate the frayed degree of contacting part 4, improve the working life of shift fork entirety.
Joint 1 offers groove 11, when joint 1 and declutch shift shaft are welded to connect, the limit that groove 11 contacts with declutch shift shaft also can be welded, and adds the bonding area of joint 1 and declutch shift shaft, thus improves firm, stability that shift fork is fixedly connected with declutch shift shaft to a certain extent.
Fork face 2 is provided with waist through hole 21, and described waist through hole 21 and joint 1 concentric design, alleviate the overall weight of shift fork, also assures that shift fork has certain Rigidity and strength simultaneously, can not show off offer through hole on 2 and rupture because of difference.
