Slide block is provided with in first cavity of described manipulation housing; One end of slide block and selection lever fixes, and is provided with the first spring for transverse shear stress selection lever between selection lever and baffle plate; And the first spring is positioned at the second cavity, the step place of the first cavity and the second cavity, is provided with the spring seat to the first spring retainer;
The both sides up and down of described slide block are provided with groove about selection lever axisymmetrical, and the sidewall of groove is slope shape;
Described manipulation housing is provided with the bolt run through for a pair; The head end of bolt is all fixed with fixture block, and fixture block is arranged in the groove of slide block; The second spring is provided with between bolt and fixture block.
Between described slide block and selection lever, via pins is fixed.
Described fixture block is steel ball or pin.
Described baffle plate is arranged on through clamping bolt and handles on housing.
The utility model has following beneficial effect: prior art of comparing, and the utility model, due on the basis of original structure, adds slide block, and slide block and selection lever are fixedly connected into by pin and are integrated; Handling installation fixture block symmetrical on housing, spring and bolt, spring is in its pre-compressed state under the effect of fixture block and bolt.When driver selects R shelves again, overcome the active force of spring and spring simultaneously, an obvious feel prompting driver can be produced; The ramp structure of slide block simultaneously, when driver selects R to keep off fast, due under the effect of momentum, fixture block can climb up slope fast, makes driver can feel light and comfortable in feel.This device improves gear selecting clearness and reliability greatly, and when especially selecting 1/2 gear position from neutral, when fixture block encounters the ramp structure of slide block, feel can make driver clearly select 1/2 gear to put in place clearly, can carry out engage a gear operation; Ramp structure on slide block, when selecting gear fast, due under the effect of momentum, fixture block can climb up slope fast, makes driver can feel more light and comfortable in feel.Reduce the requirement to driver, the clearness with gear selecting is high, and reliability is high simultaneously, the advantage that travelling comfort is good.Avoid driver to select wrong shelves to a greater extent simultaneously.And this device is applicable to spread and extensive use.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 3,4, the utility model comprises inside and offers the manipulation housing 1 of the first mutually through cavity 13 and the second cavity 14 and be installed on the baffle plate 2 handled on housing 1; The internal diameter of the first cavity 13 is less than the internal diameter of the second cavity 14; Slide block 5 is provided with in first cavity 13 of manipulation housing 1; Slide block 5 fixes with one end of selection lever 4, and is provided with the first spring 3 for transverse shear stress selection lever 4 between selection lever 4 and baffle plate 2; And the first spring 3 is positioned at the step place of the second cavity 14, first cavity 13 and the second cavity 14, is provided with the spring seat 11 spacing to the first spring 3; The both sides up and down of slide block 5 are provided with groove 12 about selection lever 4 axisymmetrical, and the sidewall of groove 12 is slope shape; Handle on housing 1 and be provided with the bolt 7 run through for a pair; The head end of bolt 7 is all fixed with fixture block, and fixture block is arranged in the groove 12 of slide block 5; The second spring 8 is provided with between bolt 7 and fixture block.Between slide block 5 and selection lever 4, via pins 6 is fixed.Fixture block is steel ball 9 or pin 10.Baffle plate 2 is arranged on through clamping bolt and handles on housing 1.
On the basis of original structure, add slide block 5, slide block 5 and selection lever 4 are fixedly connected into by pin 6 and are integrated; Be in its pre-compressed state handling under the effect at steel ball 9 and bolt 7 of installation steel ball 9, second spring 8 symmetrical on housing 1 and bolt 7, second spring 8.
Select the working principle summary of 3/4 grade of i.e. neutral: selection lever 4, under the effect of the first spring 3 and the second spring 8, is in equilibrium position, i.e. neutral gear position.
Select the summary of 1/2 grade of working principle: selection lever 4 moves right together with slide block 5, and compress the first spring 3 and move right, when the slope on slide block 5 contacts with steel ball 9, gear selecting terminates.
Select the summary of 5/6 grade of working principle: selection lever 4 is moved to the left together with slide block 5, the active force that steel ball 9 only overcomes the second spring 8 climbs up the slope of slide block 5, and when slide block 5 is with when handling the confined planes of housing 1, gear selecting terminates.
R shelves working principle is selected to sketch: selection lever 4 moves right together with slide block 5, and compress the first spring 3 and move right, when the slope of slide block 5 climbed up by steel ball 9 or pin 10, the Far Left one being gear selection position (Fig. 1) due to R shelves arranges gear selecting, therefore limit structure is provided with in speed changer inside, when selection lever 4 cannot move right again, gear selecting terminates.When driver selects R shelves again, need the active force simultaneously overcoming the first spring 3 and the second spring 8, have an obvious feel prompting driver; The ramp structure of slide block 5 simultaneously, when driver selects R to keep off fast, due under the effect of momentum, steel ball 9 or pin 10 can climb up slope fast, make driver can feel light and comfortable in feel.
This device improves gear selecting clearness and reliability greatly, and when especially selecting 1/2 gear position from neutral, when the ramp structure of slide block 5 encountered by steel ball 9 or pin 10, feel can make driver clearly select 1/2 gear to put in place clearly, can carry out engage a gear operation; Ramp structure on slide block 5, when selecting gear fast, due under the effect of momentum, steel ball 9 or pin 10 can climb up slope fast, make driver can feel more light and comfortable in feel.Avoid driver to select wrong shelves to a greater extent simultaneously.
