Specific embodiment
The utility model is further described with preferred embodiment with reference to the accompanying drawing.
It is as illustrated in fig. 1 and 2 the structural representation of the interlocking block structure of gear change system inside a kind of speed changer of the utility model
Figure, the interlocking block include interlocking block body 15, are provided centrally with centre bore 10 in interlocking block body 15, which can be with
Main shifting shaft is adapted, i.e., main shifting shaft passes through the centre bore 10.It is provided with open slot 9 on the side wall of interlocking block body 15,
The width of the open slot 9 is equal to shift fork prong thickness, and the shift fork of a certain gear can in this way be limited in the open slot 9, makes it
Only as main shifting shaft reversal means moves up and down realization gear shifting action.It is equal in the outer wall of interlocking block body 15, the two sides of open slot 9
It is provided with interlocking boss 8, two interlocking boss, 8 one radians are big, a radian is small and the side that interlocks boss 8 big in radian
It is arranged fluted 13, which can reduce the impact being linked into when reversing gear when reversing gear no synchronizer structure well, realize
The comfort and stability of shift.In addition, interlocking block body 15 lower planes be higher by interlocking boss 8 lower planes and mutually
The thickness for locking boss 8 is equal to shift fork prong width, shift fork prong can in this way be adapted with interlocking boss, and work as a certain gear
When shift fork is limited in open slot 9, the shift fork of remaining gear will receive the limitation of interlocking boss 8 and can not move up and down, from
And realize interlock function.It is additionally provided with V-arrangement boss 12 on the outer wall of interlocking block body 15, the V-arrangement boss 12 is big close to radian
Interlocking boss 8 side.In addition, being equipped with ball-type sliding block 11 in V-arrangement boss 12, which can be with outside spherical shape
Pin is adapted, and the rotary motion that interlocking block can be achieved is controlled by the rotation of external ball pin, to realize that gear selecting acts.This
Outside, the end face of V-arrangement boss 12 is made of the circular arc of two sections of rounding ofves, can be made V-arrangement boss in this way and is mounted on cabinet
Locking ball be adapted, and when shifting system is located at neutral gear, locking ball is located at the V-Bottom portion of V-type boss 12, when mutual
Closing piece clockwise or counterclockwise when, the spring in locking ball can be compressed, at this time only need to be to shift exterior bulb
Applying appropriately sized gear selecting power easily can cosily complete gear selecting movement.It is fixed to be additionally provided in the side of interlocking block body 15
Plane 14, the positioning surface 14 can be adapted with shell, five freedom degrees of interlocking block can be limited in this way, so that interlocking block can only be real
Now along the rotary motion of main shifting shaft axis.
The working principle of the utility model is as follows:
When shifting system is located at neutral gear, open slot 9, main shifting shaft reversal means and 3/4 gear shift fork prong are located at the same space
In plane, main shifting shaft reversal means can move up and down 3/4 gear shift fork of control in the axial direction and move up and down and be linked into 3/4 gear, and remaining
Limit of the gear shift fork prong by interlocking boss 8, can not move along main shifting shaft axis direction, realize interlocking.When needing to select
When selecting other gears, rotate interlocking block by external ball pin, when open slot 9 and a certain gear shift fork prong are located at same sky
Between in plane when, main shifting shaft reversal means can move control shift fork in the axial direction and be linked into corresponding gear, and remaining gear shift fork by
It to the effect of interlocking boss 8, can not be moved along main shifting shaft axis direction, realize interlocking.
Structure for speed variator reverse gear without synchronizer interlocks the groove on boss 8 when interlocking block rotation, which is chosen, reverses gear
13 will just be located in the same space plane with 5/6 gear shift fork prong.At this time because the thickness of interlocking boss 8 is less than 5/6 gear shift fork
Just the width of prong can make 5/6 gear shift fork that can move a bit of displacement along 6 gear directions of main shifting shaft axis, i.e., in this way
Can make the synchronous ring work of 6 gears so that be linked into reverse gear before input shaft it is synchronous with output shaft realization；But this displacement only enables to
6 keep off synchronous ring work, and 5/6 gear shift fork can not be made to be linked into 6 gears, and after input shaft and output shaft synchronous, main shifting shaft is stirred down
Shelves shift fork is linked into reverse gear, at this time 5/6 gear shift fork due to other spring structures effect and return to neutral gear position, i.e. transmission reverse gear
It also can be realized to be linked into when not increasing a synchronizer and reverse gear.
The above only expresses preferred embodiments of the present invention, and the description thereof is more specific and detailed, but not
Therefore it can be interpreted as that a limitation on the scope of the patent of the present invention.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the concept of the premise utility, several deformations can also be made, improves and substitutes, these all belong to
In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
