Abstract
The utility model discloses a multifunctional transmission shifting fork. The multifunctional transmission shifting fork integrally comprises a fork leg, a shift gear groove, an interlocking groove, and a reverse gear lock, wherein the fork leg is arranged in a shift gear shaft sleeve ring groove and in surface connect with a shift gear shaft sleeve; the shift gear groove is used for bearing action force transferred by a shift gear and connected with the fork leg fixedly; the interlocking groove is used for holding an interlocking part; the self-locking hole is used for assembling the self-locking and positioning parts; and the reverse gear lock is used for preventing misoperation of reverse gear shifting and connected with the forklift fixedly. The multifunctional transmission shifting fork integrates the self locking, interlocking and reverse gear locking functions, reduces the number of parts, improves the precision of the shifting fork assembly, saves the resources and lowers the production cost.
Description
Technical field
The utility model relates to a kind of gearbox, particularly relates to a kind of speed-changing box pulling fork with self-locking, interlocking and the lock function that reverses gear.
Background technique
Speed-changing box pulling fork is mainly used in the shifting vehicle gearbox process motion of driving gear cover to realize gearshift.Reverse gear for preventing disorderly to keep off, trip stop in the gearbox shifting process and miss to hang, gearbox need be provided with extra interlock, self-locking device and prevent the device that the mistake extension reverses gear.To make like this that gearbox shifting operating mechanism part is many, mechanism is complicated, assembly low precision, cost be high.
Summary of the invention
The purpose of the utility model is to propose a kind of multifunctional gear box shift fork, and it integrates self-locking, interlocking and the lock function that reverses gear, compact structure, and precision is high, and is with low cost, thereby overcome deficiency of the prior art.
For realizing the foregoing invention purpose, the utility model has adopted following technological scheme:
A kind of multifunctional gear box shift fork comprises the integrated following assembly that is provided with:
One fork pin, this fork pin place gearshift axle sleeve annular groove, and contact through face with the gearshift axle sleeve;
Be used to bear the gearshift groove of the active force that gearshift refers to transmit, this gearshift groove with pitch pin and be fixedly connected;
Be used for the ccontaining interlocking groove that is used for the part of interlocking;
Be used to assemble the self-locking hole of the part of lock-bit;
And, being used to prevent hang the lock that reverses gear that reverses gear by mistake, this lock that reverses gear is fixedly connected with the fork pin.
Preferably, the tubular construction of said fork pin was connected with sliding joining of gearshift axle.
Said gearshift groove and interlocking groove are structure as a whole, this integrative-structure and fork pin riveted fixing.
Said lock and the fork pin riveted fixing of reversing gear.
Particularly, said fork pin places gearshift axle sleeve annular groove, and it promotes the axle sleeve motion through the face contact;
Said gearshift groove adopts riveted joint to connect with the fork pin, is used to bear shift gears refer to the active force that transmits;
Said interlocking groove Bao Na is used for the part of interlocking;
Said self-locking hole is used to assemble the part of lock-bit;
The said lock that reverses gear connects with the riveted joint of fork pin, is used to prevent that the mistake extension from reversing gear.
In general, the utility model is realized gearshift through the fork pin and the groove of shifting gears, and utilizes the interlocking groove to realize the interlocking of different gear shift forks, utilizes to be installed in the interior parts realization lock-bit of self-locking hole, utilizes the lock that reverses gear to prevent that the mistake extension from reversing gear.
Compared with prior art, the advantage of the utility model is: this speed-changing box pulling fork integrates self-locking, interlocking and the lock function that reverses gear, and has reduced number of spare parts, has improved the pull-fork assembly precision, economizes on resources and has reduced cost of production.
Description of drawings
Fig. 1 is the structural representation of speed-changing box pulling fork in the utility model one preferred embodiment.
Embodiment
Further specify below in conjunction with accompanying drawing and a preferred embodiment technological scheme the utility model.
Consult Fig. 1, the related speed-changing box pulling fork of present embodiment mainly is made up of fork pin 1, gearshift groove 2, interlocking groove 3, the self-locking hole 4 of integrated setting and the lock 5 that reverses gear; Wherein, the tubular construction of fork pin 1 is used for being connected with sliding joining of gearshift axle, assembles automatic locking positioning device in the self-locking hole 4, like spring and steel ball, utilizes the active force of steel ball and spring to realize lock-bit.Gearshift groove 2 is structure as a whole with interlocking groove 3, adopts clinching method affixed with fork pin 1, and the gearshift groove is used to bear gearshift and refers to the active force that transmits, and interlocking groove Bao Na is used for the parts of interlocking, to realize the interlocking of different gear shift forks.The lock 5 that reverses gear adopts clinching methods to be connected with fork pin 1, withdraws from the gearshift that the back directly hangs neutral from the forward gear with respect to the side of reversing gear and refers to through blocking, and prevents that extension reverses gear by mistake.The fork pin places gearshift axle sleeve annular groove, and the active force that the gearshift groove bears contacts with axle sleeve land face through the fork pin and promotes the axle sleeve motion, to realize gearshift.
This speed-changing box pulling fork collection self-locking, interlocking and reverse gear and lock in one have reduced number of spare parts, have improved the shifting fork assembly precision, economize on resources and have reduced cost of production.
The foregoing description is merely the technological method and the thinking of explanation the utility model, and its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, but can not limit the protection domain of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the utility model.
