Abstract
A clamping stagnation prevention structure of a gearshift mechanism of an automobile speed changer is a solution scheme aiming at the problem of gear shift deadlocking of an automobile speed changer. An oil drain hole is arranged on a sleeved head part on a gearshift shaft interlock pin on speed changer gearshift shift forks. One end of the oil drain hole is communicated through a transverse hole of the sleeved head part, and the other end is communicated to the outside of the shift fork sleeved head part to communicate with the air outside, so that compressed gas and lubricating oil can be discharged outside a shift fork along an oil discharge groove, when a driver shifts gears; an interlock pin can be smoothly slide to the other side to achieve the purpose of gear shift; and the phenomenon of the gear shift deadlocking and being unable to engage with the gear, because of the oil or gas discharging blocking inside the speed changer can be effectively solved.
Description
Technical field
The utility model relates to gearshift mechanism of automotive transmission, is specifically related to the anti-clamping stagnation structure of gearshift mechanism of automotive transmission.
Background technique
In the automotive transmission structure, there is quite a few to adopt the middle cylinder that is, two ends are that the interlocking plunger of sphere carries out the gear interlocking.Its principle is the interlocking groove on the interlocking plunger corresponding two adjacent gearshift axles, during gearshift wherein a gearshift axle move axially, interlocking plunger just moves in the cross-drilled hole in the selector fork therein, supports toward the interlocking groove of another gearshift axle, another gearshift axle can't be moved, reach the purpose of gear interlocking.But this structure is because behind the interlocking plunger threading selector fork cross-drilled hole, the trepanning that this selector fork is installed the gearshift axle just becomes a more airtight space, this will cause being full of in the selector fork cross-drilled hole pressurized gas and lubricant oil, when crash change of speed, gap between gearshift axle and the shift fork is not enough to interior air gas or the lubricant oil of evacuation aperture at short notice, cause interlocking plunger to move, it is stuck to form gearshift.The gap can address this problem between gearshift axle and the shift fork though increase, consider shift fork will by the gearshift spindle guide to, the scheme that therefore strengthens gearshift axle and shift fork gap is infeasible.
The model utility content
The problems referred to above that the utility model exists at prior art, a kind of anti-clamping stagnation structure of gearshift mechanism of automotive transmission is proposed, under the prerequisite that does not influence positioning and guiding, make the driver when gearshift, pressurized gas and lubricant oil can be discharged outside the shift fork, allow interlocking plunger slide into opposite side smoothly, reach the purpose of smooth gearshift.
For achieving the above object, the technological scheme of employing of the present utility model is as follows:
A kind of anti-clamping stagnation structure of gearshift mechanism of automotive transmission, it comprises each gearshift axle and corresponding selector fork, interlocking plunger; Described each selector fork is separately fixed on each self-corresponding gearshift axle, each gearshift axle sequential parallel is arranged, between the gearshift axle interlocking plunger is set respectively, every gearshift axle on the side surface of interlocking plunger, all be shaped on the interlocking groove, when arbitrary gearshift axle was in neutral gear position, the interlocking groove part of its side was just in time aimed at interlocking plunger; Described interlocking plunger is assemblied in the cross-drilled hole of cover head of a selector fork in two adjacent gears slidably, and the trepanning vertical connection of gearshift axle is installed in described cross-drilled hole and the cover head;
It is characterized in that: be shaped on oil drainage hole on described cover head, described oil drainage hole one end is communicated with by the cross-drilled hole of cover head, thereby is communicated with the interlocking groove of corresponding gearshift axle, and the other end passes to beyond the shift fork cover head, connects with ambient air.
This structure is the stuck structure of problem of a kind of comparatively easy and effective solution shift of transmission, it increases oil drainage hole by the groove of each gearshift axle interlocking plunger of speed changer, make the driver when gearshift, pressurized gas and lubricant oil can be outside oil drainage hole be discharged shift fork, allow interlocking plunger slide into opposite side smoothly, reach the purpose of smooth gearshift.This device because inner oil extraction of speed changer or exhaust are not smooth, causes the stuck phenomenon that can't put into gear of gearshift to have positive reality and directive significance for solving.

Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As Fig. 1, a kind of anti-clamping stagnation structure of gearshift mechanism of automotive transmission, it comprises 1, No. two gearshift axle 3 of a gearshift axle and a corresponding selector fork 2 and No. two selector forks 5.Each selector fork is separately fixed on each self-corresponding gearshift axle, between 1 and No. two gearshift axle 3 of a gearshift axle interlocking plunger 4 is set, every gearshift axle on the side surface of interlocking plunger 4, all be shaped on interlocking groove 7, when arbitrary gearshift axle was in neutral gear position, the interlocking groove part of its side was just in time aimed at interlocking plunger.This interlocking plunger 4 is assemblied in the cross-drilled hole of cover head of No. two selector forks 5 slidably, and the trepanning vertical connection of gearshift axle is installed in described cross-drilled hole and the cover head.This scheme is the cover head designing and arranging oilhole 6 at No. two selector forks 5 of speed changer, and this Kong Yiduan is communicated with the cross-drilled hole of cover in the head, thereby connects with interlocking groove 7, and the other end passes to shift fork and overlaps beyond the head, connects with ambient air.
When driver's steering vehicle hung up certain retaining, interlocking plunger 4 was states shown in Fig. 2 and Fig. 2 A, and its left side sphere is to be stuck in the interlocking groove of a gearshift axle 1, prevents to hang up another retaining.When putting into gear fast this moment, need stir gearshift axle 1 No. one, drive selector fork 2 simultaneously No. one.This moment, interlocking plunger 4 certainly will support in the past along the turn right axle 3 of shifting gears for No. two of the cross-drilled hole of the cover head of No. two selector forks 5, pressurized gas of Dai Donging and lubricant oil just can be along the cross-drilled hole that overlaps head outside No. two selector forks 5 of oil drainage hole 6 discharges (as shown in Figure 4) simultaneously, allow interlocking plunger 4 slide into opposite side smoothly, prop up the interlocking groove of No. two gearshift axles 3, shown in Fig. 3 and Fig. 3 A, smoothness is shifted gears and the purpose of gear interlocking thereby reach.
