The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: joint 17 is led in the front end 6 of block selecting drag-line 1, gearshift drag-line 2, shifting drag-line support 3, block selecting Rocker arm 4, gearshift Rocker arm 5, speed change bonnet, block selecting drag-line axis hole 7, block selecting attachment pegs 8, block selecting axle 9, block selecting torsion spring 10, gearshift drag-line axis hole 12, gearshift attachment pegs 13, gearshift axle 14, block selecting backguy, the gearshift backguy is led joint 18, change-speed box in-to-in gearshift 19.Annexation is: block selecting drag-line 1 passes the block selecting drag-line hole 7 on the shifting drag-line support 3, is connected by block selecting attachment pegs 8 and block selecting Rocker arm 4 pin connection.Block selecting drag-line 1 leads the position that joint 17 is stabilized in block selecting drag-line hole 7 by the block selecting backguy.And the block selecting Rocker arm 4 joins by block selecting axle 9 and block selecting torsion spring 10, change-speed box in-to-in block selecting mechanism pin, and finishes block selecting by acting on power drive change-speed box in-to-in block selecting mechanisms different on the block selecting torsion spring 10.Shifting drag-line support 3 is fixed on the front end 6 of speed change bonnet by two bolts 16.Gearshift drag-line 2 passes the gearshift drag-line hole 12 on the shifting drag-line support 3, is connected by gearshift attachment pegs 13 and gearshift Rocker arm 5 pin connection.Gearshift drag-line 2 leads the position that joint 18 is stabilized in gearshift drag-line hole 12 by the gearshift backguy.And the gearshift Rocker arm 5 links to each other with change-speed box in-to-in gearshift by gearshift axle 14, and by acting on the power drive change-speed box in-to-in gearshift 19 on the gearshift axle 14, finishes gearshift.
Shifting drag-line support 3 is integrated, form by three faces, similar h type, be upwards 90 ° the plane of band block selecting drag-line axis hole 7 and gearshift drag-line axis hole 12 on one side, shifting drag-line axis hole lays respectively at the both sides on this plane, the position of block selecting drag-line axis hole 7 and gearshift drag-line axis hole 12 determines that according to the position of two rocking arms gearshift drag-line axis hole 12 is consistent with level, and block selecting drag-line axis hole 7 becomes 12.5 ° with level.When block selecting drag-line 1 passed block selecting drag-line axis hole 7, it was stable to lead joint 17 by the block selecting backguy.When gearshift drag-line 2 passed gearshift drag-line axis hole 12, it was stable to lead joint 18 by the gearshift backguy.Another side is the downward 90 ° plane with two bolts hole 11, and two bolts hole 11 lay respectively at the both sides on this plane, is used for fixing gearshift drag-line support 3.
The block selecting Rocker arm 4 also is integrated, and the similar U type of shape, an end of U type are block selecting attachment pegs 8 upwards, is used for connecting with block selecting drag-line 1 pin connection, and the other end is downward block selecting axle 9, is used for by block selecting torsion spring 10 and change-speed box in-to-in block selecting mechanism pin connection.
The gearshift Rocker arm 5 is integrated equally, is a bar that four foldings are arranged, and an end is a gearshift attachment pegs 13 to the right, is used for linking to each other with gearshift drag-line 2, and the clump weight 15 of the circle of the other end is used for stable gearshift rocking arm, and increases the feel of gearshift.Gearshift axle 14 is to the right arranged at the second folding place, be used for joining with change-speed box in-to-in gearshift pin.
Shifting drag-line support 3, the block selecting Rocker arm 4, the size of each size of gearshift Rocker arm 5 is decided by the size of different change-speed boxs.
When wanting block selecting, application force makes block selecting drag-line 1 stressed, block selecting drag-line 1 is through block selecting drag-line axis hole 7, act on the block selecting attachment pegs 8, make the block selecting Rocker arm 4 stressed, and drive 9 rotations of block selecting axle, block selecting axle 9 is then by block selecting torsion spring 10, stir the block selecting shifting block in the change-speed box, thereby realized the block selecting of one/two, three/four, the five/position of reversing gear.
As shown in Figure 5, usually during block selecting the size of general block selecting power about 15N.Now establishing the hand application force is T1, and the block selecting application force is F1, so according to the relation of application force and antagonistic force, acts on the size and Orientation that the F1 ' on the block selecting attachment pegs attachment pegs 8 equals.In addition, be wired to 90 ° between the direction of F1 ' power and block selecting axle 9 and the block selecting attachment pegs 8, the moment that produces does not have extra loss, act on fully on the block selecting axle 9, make and produce moment M ' on the block selecting axle 9, moment M ' overcomes moment of elasticity M on the block selecting torsion spring 10, can be drawn by block selecting torsion spring 10, measures 10 moments that can provide of torsion spring according to the material of torsion spring 10, sectional area, number of turn etc.: five/reversing gear is 2100Nmm; One/two retaining is 1600Nmm.Check five/fall stressed, hand application force T1 can obtain:
By 50F1 '=M,
M＝2100
And F1=F1 '=42Nmm
Lever ratio by joystick obtains:
65F1＝243T1
T1＝11.2N·mm
The result proves that this mechanism's block selecting power is littler than expection.
In the time will shifting gears, application force makes gearshift drag-line 2 stressed, and block selecting drag-line 2 is through gearshift drag-line axis hole 12, act on the gearshift attachment pegs 13, make the gearshift Rocker arm 5 stressed, and drive 14 rotations of gearshift axle, stirred on the gearshift 19 in the change-speed box and realized that gear changes high and low retaining.
As shown in Figure 6, it is big that generally gearshift power is wanted, about 65N.If application force T2, the gearshift application force is F2, tensile force f 2 promptly acts on the block selecting drag-line 2, arrive gearshift attachment pegs 13, because the relation of application force and antagonistic force, generation power F2 ', direction is opposite, equal and opposite in direction, gearshift shifting block bulb in the gearshift 19 in gearshift attachment pegs 13, gearshift axle 14 and the change-speed box has structurally formed one group of lever ratio (as Fig. 3) again, after this group lever ratio, the gearshift shifting block bulb place of the gearshift 19 in change-speed box produces thrust N2, and thrust N2 acts at last on the gearshift shifting block and realized that gear changes high and low retaining.
According to the influence of the factors such as sectional area of material, gearshift shifting block bulb, the maximum holding capacity of the gearshift shifting block bulb of the gearshift 19 in the change-speed box is 250N, and promptly the maximum, force of N2 is [250] N:
32·N2＝35.5·F2’
The substitution of N2 value is got:
And F2=F2 '=[225.4] Nmm
Obtain by lever ratio by joystick:
65·F2＝243·T2
T2＝[60.3]N·mm
The power limit that is T2 is no more than about 60Nmm.
By calculating than expecting to such an extent that value is little, gearshift power is little.
So the choosing of the utility model structure, gearshift power are little, use light.
