Block 5, select the feel block 6 that reverses gear.In correct position increase feel pin assembly 7, feel pin assembly 7 assembles band successively from inside to outside
The ejector pin 9 of rolling steel balls 8, cylindrical spring (the second flexible member) 10, packing ring 11 and nut 12.Shifting shifting block 1 is in block selecting
In shift process, the part in open recess 14 contacts the second flexible member 10 of compression with rolling steel balls 8 and produces feel power.
As shown in Figure 1-2, shift-feel block 4 is rectangular block structure, and its inner side long side is concordant with the inwall of open recess 14, its
Outer long side edge is arc structure, and arc structure stretches out the outward flange of open recess 14；Described choosing reverse gear the inner side of feel block 6 with
The inwall of open recess 14 is concordant, and its outside sets raised, and two choosings are reversed gear and form the first groove between feel block 6；Described block selecting
The groove gap of feel block 5 and first coordinates, and the outside of block selecting feel block 5 is provided with tip.Formed between two tips for positioning sky
Second groove of gear；Sophisticated the 3rd groove formed between projection for positioning 1,2 gears of side, raised outside is formed for positioning
The 4th groove to reverse gear, sophisticated the 5th groove formed between projection for positioning 5,6 gears of opposite side.The top of open recess 14 and
The quantity of half slot 13 of bottom margin is four, and is correspondingly arranged up and down；Four half slots are corresponding in turn to the 4th groove, the 3rd
Groove, the second groove and the 5th groove.First groove inwall is inclined-plane, block selecting feel block 5 and the first slot structure to matching, two block selecting feels
Block 5 leaves gap.
When speed changer is in neutral gear position, first flexible member of the inside of shifting shifting block 12 and feel pin assembly 7
In same center, rolling steel balls 8 are arranged in the second groove, and block selecting feel block 5 is arranged on the bottom of the first groove, the first elasticity
Element 2 is in compressive state, and the second flexible member 10 is in compressive state.First flexible member 2 and the second flexible member 10 are equal
For spring.
Through hole on block selecting feel block 5 coordinates with the gap of bolt assembly 3.The diameter of half slot 13 is less than rolling steel balls 8
Diameter.Fixed seat 12 is connected with case of transmission, the shifting axis connection of shifting shifting block 1 and speed changer.
With reference to Fig. 2-1 to Fig. 5, the utility model principle of specifically shifting gears is as follows：
(1) when selecting gear shifting pulling head 1 to be in neutral gear position in feel pin assembly 7 and the open recess 14 of shifting shifting block 1
Hole is concentric.When selecting gear shifting pulling head 1 to be acted on axial movement by external force, the block selecting feel block 5 for being machined with long slot bore is made in ejector pin 9
Under, moved on the boss cylinder of shift-feel block 4 to inside shifting block open recess 14 so as to compress bullet in the hole of open recess 14
Spring 2.Feel block 6 is reversed gear in choosing and shift-feel block 4 is fixed in the open recess 14 of shifting shifting block 1 by hexagon-headed bolt.
(2) in shifting shifting block 1 by the gear of neutral selection 1/2 or during reversing gear, the axle under external force of shifting shifting block 1
To movement, block selecting feel block 5 and choosing are reversed gear the slip relative with the ejector pin with rolling steel balls 8 of feel block 6, now block selecting feel block 5
With the geo-stationary of shifting shifting block 1, ejector pin slides to block selecting feel block 5 and forms block selecting suction sense after selecting the top of feel block 6 of reversing gear；
In shifting shifting block 1 by 1/2 gear or during reversing gear and retracting neutral, work of the block selecting feel block 5 in the ejector pin 9 with rolling steel balls 8
The hole inner spring of open recess 14 is compressed to inside the open recess 14 of shifting shifting block 1 with the lower boss cylinder along shift-feel block 4
It is mobile, shifting shifting block 1 is easily precisely returned to neutral gear position, while the hole inner spring 2 of open recess 14 is by block selecting feel block 5
Recover to initial position.
(3) during shifting shifting block 1 hangs random shift, shifting shifting block 1 is rotated under external force, gearshift
Feel block 4 is relative with the ejector pin 9 with rolling steel balls 8 to be slided, and the ejector pin 9 with rolling steel balls 8 slides to the skewed slot of shift-feel block 4
Gearshift suction sense is formed behind top.When selecting gear shifting pulling head 1 to be suspended to random shift, the ejector pin with rolling steel balls 8 is pointing exactly to half
Circular groove, and then ejector pin is spacing to the progress of shifting block upper half-round slot, is finally reached reduction in gear gap purpose.
The course of work of the present utility model is as follows：
When speed changer is in neutral gear position (such as Fig. 1-1), the contained spring 2 of shifting shifting block 1 and feel pin assembly 7
In same center.
During speed changer is by the gear (such as Fig. 3-2) of neutral (such as Fig. 2-2) selection 1/2, shifting shifting block 1 is used in outer masterpiece
Lower axial movement, block selecting feel block 5 is relative with the ejector pin 9 with rolling steel balls 8 to be slided, and now block selecting feel block 5 is dialled with shifting
First 1 geo-stationary, ejector pin 9 form block selecting suction sense after sliding to the top of block selecting feel block 5.
During speed changer retracts neutral (such as Fig. 2-2) by 1/2 gear (such as Fig. 3-2), block selecting feel block 5 rolls steel in band
The hole inner spring 2 of open recess 14 is compressed to shifting shifting block 1 along the boss cylinder of shift-feel block 4 in the presence of the ejector pin 9 of ball 8
The inside of open recess 14 is mobile, shifting shifting block 1 is easily precisely returned to neutral gear position, while the hole inner spring of open recess 14
2 recover block selecting feel block 5 to initial position.
During speed changer reverses gear (such as Fig. 4) by neutral (such as Fig. 2-2) selection, shifting shifting block 1 is under external force
Move axially, choosing is reversed gear, and feel block 6 is relative with the ejector pin 9 with rolling steel balls 8 to be slided, and now selects reverse gear feel block 6 and shifting
The geo-stationary of shifting block 1, ejector pin 9, which slides to choosing and reversed gear, forms block selecting suction sense behind the top of feel block 6.
When speed changer is by reversing gear during (such as Fig. 4) retract neutral (such as Fig. 2-2), although the ejector pin 9 with rolling steel balls 8 is right
The return of shifting shifting block 1 has certain resistance, but choosing displacement of reversing gear is big, shifting shifting block 1 also can be easily crossed choosing and reverses gear feel
Block 6, and repeat to retract neutral step by 1/2 gear, finally precisely return to neutral gear position.
During speed changer hangs random shift (such as Fig. 5) by neutral (such as Fig. 2-2), shifting shifting block 1 is used in outer masterpiece
Under rotated, shift-feel block 4 and the ejector pin 9 with rolling steel balls 8 are relative to be slided, and the ejector pin 9 with rolling steel balls 8 slides to gearshift
Gearshift suction sense is formed after the top of the chute of feel block 4.
When elected gear shifting pulling head 1 is suspended to random shift (such as Fig. 5), the ejector pin 9 with rolling steel balls 8 is pointing exactly to half slot,
And then ejector pin 9 is spacing to the progress of shifting block upper half-round slot, reduction is finally reached in gear gap purpose.
More than, preferred embodiment only of the present utility model, it is not limited only to practical range of the present utility model, Fan Yiben
The equivalence changes and modification that the content of utility model scope is done, it all should be technology category of the present utility model.
