Description
Technical field
The utility model relates to a kind of speed change locking framework, particularly a kind of motor vehicle speed change locking framework.
Background technique
At present, motor vehicle speed change locking framework generally all is to be made of the groove on the gearshift axle, locking steel ball and self-locking spring.This speed change locking framework is realized locking by the pretightening force of self-locking spring, must overcome this pretightening force when gearshift, can't unlock, and the problem of existence is, if pretightening force is big inadequately, then easily in the vehicle operating process off-gear cause danger; If continue to increase pretightening force, then increase the gearshift difficulty, and still cannot say for sure to demonstrate,prove not off-gear.
Summary of the invention
The purpose of this utility model is, provides a kind of and can overcome existing speed change locking framework deficiency, and the reliable and release of locking is the speed change locking framework completely.
The technical solution of the utility model is: it also comprises special gearshift shaft locking mechanism and locking operating mechanism except that comprising the gearshift axle.
Its gearshift shaft locking mechanism can be separated the lock shaft of locked groove for band, and also have groove on the gearshift axle, separate locked groove when corresponding with the gearshift axle position on this lock shaft, gearshift spool can be twitched, this separates that locked groove staggers with gearshift axle and lock shaft when embedding in the gearshift axle groove, and the gearshift axle is locked.
Its gearshift shaft locking mechanism can be lock pin, and has groove or hole on the gearshift axle, lock pin on inserting the gearshift axle groove or the hole in the time, the gearshift shaft lock is fixed, lock pin is when the gearshift axle is deviate from, the gearshift axle can move axially.
Its gearshift shaft locking mechanism can also for, band is separated the lock shaft and the locking steel ball between lock shaft and gearshift axle of locked groove, have groove on the gearshift axle, on the lock shaft separate locked groove with locking steel ball when staggering, the locked steel ball locking of gearshift axle, when the locking steel ball fall on the lock shaft separate locked groove the time, the locking steel ball can be deviate from from gearshift axle groove, the gearshift axle can move axially.
The utility model has been owing to increased special gearshift shaft locking mechanism, thus can conveniently accomplish positive lock, and release is thorough, thus make vehicle operating safer, and it is also more laborsaving to shift gears.

Embodiment
In attached Fig. 1 and 2 illustrated embodiment, have annular groove on three gearshift axles 1, this groove is equipped with interlocking steel ball 2 as interlock slot respectively between adjacent gearshift axle 1.Lock shaft 3 is a circular shaft, a processed plane on the axle, and this plane length reaches three gearshift axles 1, separates locked groove for three that are equivalent to be linked to together, between lock shaft 3 and the gearshift axle 1 locking steel ball 4 is arranged.Crank 6 is equipped with in the end of described lock shaft 3, and return spring 7 and operating handle 8 are housed on the crank 6, and operating handle 8 links with on-off control mechanism.Like this, when gearshift front control on-off control mechanism, operating handle 8 drives lock shaft 3 rotations by crank 6, it is relative with the position that locks steel ball 4 that plane on the lock shaft 3 rotates to, thereby locking steel ball 4 can come out from the groove of gearshift axle 1 under gearshift power effect, when hanging up properly after retaining loosens on-off control mechanism, under the effect of return spring 7, stagger with locking steel ball 4 in plane on the lock shaft 3, locking steel ball 4 is crushed in the groove of gearshift axle 1, can not deviate from.For preventing that lock shaft 3 from deviating from, be processed with a circular groove thereon, the head of stop screw 12 drops in this circular groove.The effect of two interlocking steel balls between the axle 1 of shifting gears is to prevent random retaining.
Accompanying drawing 3 is compared with the foregoing description with 4 illustrated embodiments, has increased self-locking steel ball 9 and self-locking spring 10, and self-locking spring 10 is pressed on the self-locking steel ball 9, and on the lock shaft 3 three separate locked groove and are not associated in together.The benefit that increases self-locking spring 10 and self-locking steel ball 9 is the gearshift good hand touch.This embodiment's working method is also all identical with previous embodiment with action principle.
In accompanying drawing 5 illustrated embodiments, gearshift axle 1 band groove, the self-locking spring 10 that is contained in the self-locking steel ball 9 in the groove and is pressed on the self-locking steel ball 9 is being shifted gears between axle 1 and the lock shaft 3, separate locked groove on the lock shaft 3, locking steel ball 4 is between lock shaft 3 and self-locking spring 10, and lock 5 is contained in the self-locking spring 10.This assembly relation should guarantee, during separating locked groove and stagger with locking steel ball 4 on the lock shaft 3, self-locking steel ball 9 is crushed in the groove of gearshift axle 1 to deviate from, locking steel ball 4 fall on the lock shaft 3 separate locked groove the time, self-locking steel ball 9 can be deviate from from the groove of gearshift axle 1.Among this embodiment, lock shaft 3 along the axial direction moving linearly, for release reliably puts in place, is provided with positive stop lug boss on lock shaft 3 in the process of release gearshift axle 1; Return spring 7 and stear drawing line 11 are housed on the lock shaft 3, and stear drawing line 11 links with on-off control mechanism.Like this, when handling on-off control mechanism, stear drawing line 11 pulling lock shafts 3, make locking steel ball 4 fall into separating in the locked groove of lock shaft 3, locking framework is in released state, thereby self-locking steel ball 9 can take off from the groove of gearshift axle 1 to realize gearshift, because the effect of self-locking spring 10, the gearshift feel is better; After loosening on-off control mechanism, under the effect of return spring 7, lock shaft 3 retreats, and locking steel ball 4 comes out from the locked groove of separating of lock shaft 3, and lock shaft 3 is pressed in self-locking steel ball 9 in the groove of gearshift axle 1 by locking steel ball 4 and lock 5, no longer can deviate from.
The utility model is not limited to above-mentioned several mode of execution, multiple conversion and remodeling can also be arranged, as shift gears shaft locking mechanism can for, have groove on the gearshift axle, have on the lock shaft and separate locked groove, as long as separate locked groove and gearshift axle position when corresponding on the lock shaft, gearshift spool can move axially, with gearshift axle on groove when staggering, the gearshift axle can not move axially just can.Equally, when lock state, can not move axially, when released state, can move axially as long as guarantee the gearshift axle, can be porose on the gearshift axle, but gearshift shaft locking mechanism lock pin.The locking operating mechanism is not if link with the clutch control system, and Joystick is loaded onto at position that can also staff can directly grip on gear level, and this handle by backguy or pull bar is final and gear level links just.
