Abstract
The utility model relates to an interlocking device for a shifting rod of a transmission case. A through hole is arranged in a cover of the transmission case, a shifting fork shaft is mounted in the through hole, a shifting block is mounted on the shifting fork shaft, guide tracks are arranged on the two long sides of the through hole, a gearshift interlocking plate is arranged on the guide tracks, a crisscross guide hole is arranged on the gearshift interlocking plate, four cuboids are respectively arranged on the sides which are in fit with the crisscross guide hole on the bottom surface of the gearshift interlocking plate, and a crisscross guide groove which is in fit with the crisscross guide hole is constituted by the four cuboids. The shifting rod can shift the shifting block to move along the crisscross guide groove, realize the functions of gear engagement, gear disengagement and neutral gear, enable the shifting rod and the shifting block to always keep positioning and interlocking linkage in each gear position under the action of the gearshift interlocking plate, easily realize gear engagement, gear disengagement and neutral gear and avoid the occurrence of out-of-gear and disorder of gear phenomena, has the advantages of compact structure, convenience in manipulation, accurate positioning and reliability in working, and is in line with the requirements of structural design of an operating mechanism of the transmission case.
Description
Technical field
The utility model relates to a kind of gearbox, relates in particular to a kind of gear box deflector rod interlock of gearbox operating mechanism.
Background technique
In gearbox operating mechanism, the general position device of not setting between driving lever and the shifting block, driving lever slides in the shifting block groove, realizes putting into gear or plucking gear, and this structure gearbox is random gear easily; Though some gearbox is provided with fixing gearshift interlock board, it is smooth and easy not when driving lever slides in fixing gearshift interlock board guide groove, so it is more painstaking to handle, driving lever and gearshift interlock board contacts the wearing and tearing that can cause guide groove again, time has been grown, has worn and torn large will cause the inaccurate difficult gearshift of gear, easy phenomenon of disorderly keeping off to occur, gearbox operating mechanism, it requires reliable operation, handiness, good manufacturability, occupies than consequence in structural design.
The model utility content
In order to overcome the shortcoming of prior art, in order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of compact overall structure, can light realization put into gear, pluck gear, neutral; Remain between driving lever and the shifting block that interlocking connects; Avoid off-gear and disorderly keep off the gear box deflector rod interlock that phenomenon occurs.
The technological method that its technical problem that solves the utility model adopts is: a kind of gear box deflector rod interlock, comprise gear shift cover, in gear shift cover, be provided with open-work, declutch shift shaft is installed in open-work, at declutch shift shaft shifting block is installed, two long limits of described open-work are provided with guide rail, at guide rail the gearshift interlock board is housed, be provided with in length and breadth to " ten " word guide hole at this gearshift interlock board, be provided with in the bottom surface of gearshift interlock board and be respectively equipped with four cuboids on the limit to " ten " word guide hole in length and breadth, by four cuboids forms and above-mentioned in length and breadth to " ten " word guide hole match in length and breadth to " ten " word guide groove.
The beneficial effects of the utility model are: install the gearshift interlock board between driving lever and shifting block, being sleeved on the shifting block of declutch shift shaft to " ten " word guide groove in length and breadth on the gearshift interlock board, the gearshift interlock board just can be in guide rail under the driving lever effect and the shifting block selection gear that moves laterally, when choosing gear, driving lever is stirred shifting block and is being vertically moved to " ten " word guide groove in length and breadth, realizes putting into gear, plucking the function of gear, neutral.Under gearshift interlock board effect, remain location between each gear driving lever and the shifting block, interlock and connect; Can light realization put into gear, pluck gear, neutral, avoid off-gear and disorderly gear phenomenon generation; Advantage with compact structure, handiness, accurate positioning, reliable operation meets the Structural Design Requirement of gearbox operating mechanism.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is gearshift interlock board 3 reverse side structural drawing among Fig. 1.
Fig. 3 is Fig. 2 side view.
Fig. 4 is Fig. 2 worm's eye view.
Among the figure: 1-gear shift cover, 2-open-work, 3-declutch shift shaft, 4-shifting block, 5-guide rail, 6-gearshift interlock board, 7-in length and breadth to " ten " word guide hole, 8-cuboid, 9-in length and breadth to " ten " word guide groove.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of gear box deflector rod interlock, comprise gear shift cover 1, in gear shift cover 1, be provided with open-work 2, declutch shift shaft 3 is installed in open-work 2, at declutch shift shaft 3 shifting block 4 is installed, two long limits of described open-work 4 are provided with guide rail 5, at guide rail 5 gearshift interlock board 6 is housed, be provided with in length and breadth to " ten " word guide hole 7 at this gearshift interlock board 6, be provided with in the bottom surface of gearshift interlock board 6 and be respectively equipped with four cuboids 8 on the limit to " ten " word guide hole 7 in length and breadth, by four cuboids 8 forms and above-mentioned in length and breadth to " ten " word guide hole 7 match in length and breadth to " ten " word guide groove 9.In the practical application, the shifting block 4 of declutch shift shaft 3 is sleeved on is provided with in length and breadth to " ten " word guide hole 7 and is provided with in length and breadth in the gearshift interlock board 6 of " ten " word guide groove 9, when just can driving gearshift interlock board 6, stirring of driving lever move at the guide rail 5 of gear shift cover 1 guide hole 2, at the shifting block 4 selection gear that moves laterally, when gear chooses, shifting block 4 just can move to " ten " word guide groove 9 in length and breadth under the driving lever effect, realizes putting into gear, plucking the function of gear, neutral.Under gearshift interlock board effect, make between each gear driving lever and the shifting block 4 and remain that location, interlocking connect, avoid off-gear and disorderly keep off the phenomenon generation.The utlity model has compact overall structure, handiness, accurate positioning, reliable operation, good manufacturability, meet the Structural Design Requirement of gearbox operating mechanism.
