Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As depicted in figs. 1 and 2; A kind of gear mutual interlocking gear speed changer that has; Comprise first declutch shift shaft that is used for gearshift between a retaining and two retainings; And second declutch shift shaft of shifting gears between being used for five retainings and reversing gear, first declutch shift shaft 2 is provided with first shifting block 1 and first shift fork 3, and the first synchronous gearshift 10 that is connected with first shift fork 3; Second declutch shift shaft 5 is provided with second shifting block 4, five and keeps off the shift fork 6 and the mechanisms 7 of pulling pin of reversing gear; Be connected with synchronous gearshift 11 on the said five retaining shift forks 6; Said reverse gear to pull pin be connected with the idle pulley 12 that reverses gear in the mechanism 7; The synchronous gearshift 11 of the axial motion of second declutch shift shaft 5 control five retainings with reverse gear idle pulley 12, thereby realize five retainings and reverse gear between conversion, it also comprises the gear mutual interlocking gear; Said gear mutual interlocking gear comprises interlocking bearing pin 8 and interlocking key seat 9; Said interlocking bearing pin 8 is inserted in the hole of interlocking key seat 9, and said interlocking key seat 9 is fixedly connected on the case of transmission, and said first declutch shift shaft 2 is provided with first interlock slot 13; Be provided with second interlock slot 14 with first interlock slot, 14 corresponding positions on said second declutch shift shaft 5, the two ends of said interlocking bearing pin 8 can embed respectively in the first interlocking cotter way 14 and the second interlocking cotter way 14.
First shifting block 1 and first shift fork 3 are connected on first declutch shift shaft 2 through the resilient key cover respectively, through the axial motion control first synchronous gearshift 10 of first declutch shift shaft 2, thereby realize the gearshift between a retaining and two retainings; Second shifting block 4 and five retaining shift forks 6, the mechanism 7 of pulling pin of reversing gear are connected on second declutch shift shaft 5 through the resilient key cover respectively; Five retaining shift forks 6 are connected with the synchronous gearshift 11 of five retainings; The reverse gear mechanism 7 of pulling pin is connected with the idle pulley 12 that reverses gear; The synchronous gearshift 11 of axial motion control five retainings through second declutch shift shaft 5 with reverse gear idle pulley 12, thereby realize five retainings and change down between gearshift.
Described first shifting block 1, second shifting block 4 middle part in speed changer that is arranged in parallel links through resilient key and first declutch shift shaft 2, second declutch shift shaft 5 respectively.
Described first shift fork 3 and five retaining shift forks 6, the mechanism 7 of pulling pin of reversing gear link through resilient key and first declutch shift shaft 2, second declutch shift shaft 5 respectively, directly control the first synchronous gearshift 10, five and keep off the synchronous gearshift 11 and the idle pulleys 12 that reverse gear.
As shown in Figure 2, described interlocking bearing pin 8 is slidingly mounted in interlocking key seat 9 holes.
Described interlocking key seat 9 passes through two bolt on case of transmission.
Limit axial motion separately through the interlocking bearing pin 8 that slides in the interlocking key seat 9 between described first declutch shift shaft 2 and second declutch shift shaft 5.
After speed changer is accomplished the block selecting process, begin to carry out shift process, the gearshift shifting block stirs first shifting block 1 or second shifting block 4 moves along the gear direction of manipulator's expectation, and concrete moving direction is any one in two gears in the opposite direction.After for example accomplishing first block selecting, the operator can make the gearshift shifting block select a direction to stir, and accomplishes the shift process of a retaining or two retainings.In like manner, the shift process of accomplishing five retainings or reversing gear.
One retaining, two retainings are contained in a retaining and two retainings with five retainings, the interlock process of reversing gear, or among five retainings and the shift process that reverses gear.
When speed changer was hung into five retainings or reversed gear, second declutch shift shaft 5 promotes interlocking bearing pin 8 and in interlocking key seat 9 holes, in axial direction moves to first declutch shift shaft, 2 directions, and was final stuck in first interlock slot 13 of first declutch shift shaft 2; At this moment, first declutch shift shaft 2 can not move fully, in the case; 3 motions that can limit the first synchronous gearshift 10 fully of first shift fork; Thereby eliminate five retainings or reverse gear, can thoroughly solve in actual use, hang and reverse gear when going the design deficiency of influence of a retaining or two retainings; First synchronizer gear sleeve that possibly cause is to two retaining direction plaies; Cause the retaining of two in first synchronous gearshift synchronizer non-normal working, cause synchronous conical surface inordinate wear, cause two retaining synchronizer early failues; And then when normal driving taking place hanging two retainings, it is not enough even do not have the incipient fault hidden danger of beating tooth synchronously because of synchronizing capacity two retainings to occur.
When speed changer is hung into a retaining or two retainings; First declutch shift shaft 2 promotes interlocking bearing pin 8 and in interlocking key seat 9 holes, in axial direction moves to second declutch shift shaft, 5 directions, and is final stuck in second interlock slot 14 of second declutch shift shaft 5, at this moment; Second declutch shift shaft 5 can not move fully; In the case, five retaining shift forks 6 can limit the synchronous gearshift 11 of five retainings respectively fully and reverse gear the motion of idle pulley 12 with the mechanism 7 of pulling pin of reversing gear, thereby eliminate a retaining or the two retainings design deficiency to five retainings or the influence of reversing gear.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
