It is used merely to that people is helped to will be readily understood that the present invention, therefore the present invention is not limited thereto.
Before the gear teeth thickness of power shift gear 31 is formed as thinner, when power shift gear 31 is engaged with clutch gear 61
When, the length of action (a) between power shift gear 31 and the gear teeth of clutch gear 61 is maintained at 2mm, and the same time shift of sleeve 30
Dynamic stroke is 8.8mm.
On the contrary, power shift gear 31 be cut out a certain amount of (be denoted as deviate broken line) and it is thinning in the case where, work as shift
When gear 31 is engaged with clutch gear, the length of action (b) between power shift gear 31 and the gear teeth of clutch gear 61 increases
To 2.34mm.But since the length of action between power shift gear 31 and clutch gear 61 should be still fixed at 2mm, because
It is the more than needed of 0.34mm that increment, which has occurred, in this length of action.
In this way, the shift motion of sleeve 30 reduces the increment of 0.34mm, therefore the stroke S2 of sleeve 30 is decreased to
8.46mm is 0.34mm smaller than the original stroke (i.e. 8.8mm) of sleeve 30.
In this way, as shown in fig. 6, the steering force of speed-changing lever reduces, this is when the shift motion of sleeve 30 reduces
Because if the stroke S1 of speed-changing lever is constant, then lever ratio increases.
Meanwhile according to the present invention, center groove 32 is formed in the center that the power shift gear 31 contacted is formed with synchronous key 40
Place, and stop surfaces 33 are formed as the form of cut or cuts on the opposite side of center groove 32.As a result, when according to sleeve 30
Movement and when synchro-meshing occurs, synchronous key 40 can be formed with stop surfaces 33 and be contacted, and by the stop surfaces 33
Support.
That is, synchronous key 40 slides over from central fovea during and speed mobile with sleeve 30 changes
The opposite side of slot 32 chamfered part outstanding, and it is stopped the support of surface 33.In this way, being stopped the synchronous key of the support of surface 33
40 become engaging with chamfered part outstanding, so that it is guaranteed that firm velocity variations and preventing from the backgear of velocity variations to be detached from nibbling
It closes.
Synchronizer according to the present invention for speed changer, power shift gear 31 form first gear teeth contacted with synchronous key 40
Thickness L1 is formed larger than the second gear teeth thickness (that is, conventional use of gear teeth thickness) of power shift gear 31, so that applying
Pressure on to the surface of the power shift gear 31 contacted with synchronous key 40 is dispersed and is reduced, thus increase power shift gear 31 and
The durability of the synchronous key 40 contacted with power shift gear 31.
In addition, according to the present invention, the gear teeth thickness L2 that power shift gear 31 is engaged with clutch gear 61 is formed as thinner, from
And power shift gear 31 is generated relative to having more than needed in the length of action of clutch gear 61, so that the shift motion of sleeve 30
Reduce the more than needed of length of action.In this way, the steering force of speed-changing lever reduces when the shift motion of sleeve 30 reduces,
This is because lever ratio increases if the stroke of speed-changing lever is constant.
Further, according to the present invention, during and speed mobile with sleeve 30 changes, the sliding of synchronous key 40 is got over
It crosses from the opposite side of center groove 32 chamfered part outstanding, and is stopped the support of surface 33.In this way, being stopped 33, surface
The formation of the synchronous key 40 of support and chamfered part outstanding engage, so that it is guaranteed that velocity variations consolidated and after preventing velocity variations
Gear is disengaged from.Accordingly, because the function of latch can be substituted by construction of the invention, therefore eliminates and routinely install
Latch to save installation latch for the expense of generation, and thereby saves the weight of synchronizer.
