Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1, a kind of gear selecting and journey stop gear thereof reliably, comprise: select shift shaft 3, described choosing in the middle part of shift shaft 3 is installed with interlock board 5, gear shift 4 is provided with in interlock board 5, selecting on shift shaft 3 of interlock board 5 side is provided with linear bearing 2, ensure gear selecting time select shift shaft 3 can freedom and flexibility move axially or axial rotation carries out gear-change operation, select to be provided with outside shift shaft 3 and select gear shift seat 9, select between gear shift seat 9 and interlock board 5 and be provided with lock screw 1, lock screw 1 one end is fixed on by screw thread to be selected on gear shift seat 9, the other end is stuck in the kidney slot of interlock board 5, selecting on shift shaft 3 of interlock board 5 both sides is provided with limited location snap ring 8, return spring 6 is provided with between limited location snap ring 8 and interlock board 5.
Described limited location snap ring 8 side is provided with spacing shim 7, and spacing shim 7 is enclosed within and selects on shift shaft 3.
Described limited location snap ring 8, interlock board 5, gear shift 4 are fixedly mounted on and select on shift shaft 3.
Wherein left and right limited location snap ring 8, interlock board 5 and gear shift 4 is all fixed together with selecting shift shaft 3, and during gear selecting, these parts will move left and right with part 3; Part 2 is linear bearings, be used for ensure the gear selecting time 3 can freedom and flexibility move axially or axial rotation carries out gear-change operation etc.; Part 1 is lock screw, and its one end is fixed on by screw thread to be selected on gear shift seat 9, and the other end is stuck in the kidney slot of interlock board 5, and the limit travel being used for carrying out gear selecting is spacing, and gear selecting return is realized by left and right return spring 6; Right limit pad 7 pines in left and right are enclosed within and select on shift shaft, and have one side dependence to select gear shift seat inwall spacing!
Be illustrated in figure 2 neutral position; Now gear shift head, interlock board, left and right limited location snap ring etc. are with selecting shift shaft to be in gear selecting stroke neutral position, namely neutral position, and now axial rotation selects shift shaft then can carry out 3,4 gear shift operations,
Be illustrated in figure 3 and choose 1/2 file location; When carrying out 1/2 grade of gear selecting action, External Force Acting makes to select shift shaft to move right with left and right limited location snap ring, left limit pad, interlock board, first of gear shift, the return spring on the right is compressed formation 1/2 gear selecting power simultaneously, when to move right to design runlength always, lock screw external cylindrical surface can contact with interlock board kidney slot, thus prevention selects shift shaft to continue to move right, form gear selecting stroke limit, now namely rotatably select shift shaft to carry out changing 1,2 grade of operation
Be illustrated in figure 4 and choose 5/R file location; When carrying out the gear selecting action of 5/R shelves, External Force Acting makes to select shift shaft to be moved to the left with left and right limited location snap ring, right limit pad, interlock board, first of gear shift, the return spring on the left side is compressed and is formed 5/R gear selecting power simultaneously, when to be moved to the left to design runlength always, lock screw external cylindrical surface can contact with interlock board kidney slot, thus prevention selects shift shaft to continue to be moved to the left, form gear selecting stroke limit, now namely rotatably select shift shaft to carry out changing 5, the operation of R shelves
When selecting 1/2 grade, gear shift head, interlock board, left and right limited location snap ring, left limit pad carry out axial gear selecting motion with selecting shift shaft, right limit pad with select gear shift seat internal chamber wall to contact and do not move, contact spacing by lock screw with interlock board kidney slot when gear selecting puts in place and stop continuing to move axially.
When selecting 5/R shelves, gear shift head, interlock board, left and right limited location snap ring, right limit pad carry out axial gear selecting motion with selecting shift shaft, left limit pad with select gear shift seat internal chamber wall to contact and do not move, contact spacing by lock screw with interlock board kidney slot when gear selecting puts in place and stop continuing to move axially.
In gear selecting process, gear selecting power and gear selecting returning place force are produced by the return spring between interlock board and left and right spacing shim.Left and right spacing shim pine is enclosed within to select on shift shaft and relies on left and right limited location snap ring spacing, and moves towards interlock board direction in gear selecting process.
When selecting 1/2 grade, left limit snap ring with left limit pad together with selecting shift shaft to move right, right limit pad then to select the spacing transfixion of gear shift seat internal chamber wall, right limit snap ring also along with selecting shift shaft to move right together, until lock screw contacts with interlock board kidney slot.
When selecting 5/R shelves, right limit snap ring with right limit pad together with selecting shift shaft to be moved to the left, left limit pad then to select the spacing transfixion of gear shift seat internal chamber wall, left limit snap ring also along with selecting shift shaft to be moved to the left together, until lock screw contacts with interlock board kidney slot.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
