In more detail, referring to Fig. 5 A and Fig. 5 B, column 104 usefulness one planar member is stamped to form.One end of column 104 forms a flange part 104-1.Flange part 104-1 is determining the depth of penetration of column 104 in hole portion 102.One perforation 104-3 is arranged on the other end of column 104 or the bottom surface 104-2.
From Fig. 1 and Fig. 2 as seen, the first pit 96-1 and the second pit 96-2 are arranged on the periphery of reverse gearwheel driving lever 96.Ball spare 106 was not against the first pit 96-1 when bar 96 was not swung.During bar 96 swings, ball spare 106 is against the second pit 96-2.The volume ratio first pit 96-1 of the second pit 96-2 is little.
As shown in Figure 1, thus when finishing assembling ball spare 106 during against the first pit 96-1, the thrust that bar 96 overcomes spring 108 pushes ball spare 106 in the column 104 slightly.Thereby a very little gap " S " appears between projection 110 and the ball spare 106.
In this embodiment, projection 110 is to pound the limit by an end of column 104 to form.
The following describes the service condition of this embodiment.
In the column 104 of before the hole portion 102 that column 104 is inserted front gear boxs 46, spring 108 being packed into.When spring 108 is subjected to 106 compressions of ball spare, an end of column 104 is pounded the limit, thereby form projection 110, prevent that ball spare 106 from ejecting column 104.
Then in the column 104 patchhole portions 102.
At this moment, the flange part 104-1 of column 104 1 ends is determining the depth of penetration of column 104 in hole portion 102.
When assembling was finished, as shown in Figure 1, ball spare 106 was against the first pit 96-1 of reverse gearwheel driving lever 96.The thrust that bar 96 overcomes spring 108 pushes ball spare 106 in the column 104 slightly.Thereby generate a minim gap " S " between projection 110 and the ball spare 106.
As shown in Figure 2, when when bar 96 swing reverse gear idler gear 60 being slided vertically, ball spare 106 is pushed away and against the second pit 96-2 of bar 96.Therefore, generate another gap between projection 110 and the ball spare 106 greater than above-mentioned gap " S ".
Therefore, being formed on cylindrical in the front gear box 46 of change speed gear box 10 has not perforated 102 at the end to make the exterior clutch chamber of this gear transmission not be communicated with this gear transmission in-to-in gear chamber.Therefore leakage of oil can not take place, thereby help actual use.
In addition, detent mechanism 100 structures make the hole portion 102 that comprises, column 104, ball spare 106 and spring 108.Therefore, but three parts of detent mechanism 100 are column 104, ball spare 106 and spring 108 assembled in advance is in the same place.Therefore need only be just finishing whole fitting work in the column 104 patchhole portions 102 that are pre-assembled.This feature reduction fitting work, part number reduce, cost reduces, thereby more economical.
In addition, column 104 has projection 110 in flange part 104-1 inside, prevents that ball spare 106 from coming off on the one hand, can position ball spare 106 on the other hand.Therefore projection 110 makes ball spare 106 to eject from column 104.This feature has improved reliability, the simplification that helps assembling.
And, when ball spare 106 is against the first pit 96-1 finishing assembling between projection 110 and the ball spare 106 very little gap " S " appears.Therefore projection 110 does not change the position after ball spare 106 assembles.Therefore when forming projection 110, need not to improve dimensional accuracy.Therefore projection 110 is convenient to make.
In addition, form projection 110, so the making of projection 110 is simplified owing to an end of column 104 is pounded the limit.This helps actual use.
Should see, the invention is not restricted to the foregoing description, and can carry out all changes and correction.
For example, according to the foregoing description, an end of column 104 forms projection 110 by pounding the limit.Fig. 6 illustrates another embodiment.Exactly, an end of column 104 is collapsible and form a projection 112.Therefore, with the foregoing description to pound the limit the same, the making of projection 112 is simplified.This helps actual use.
In addition, according to the foregoing description, the protrusion in the column 104 is a ball spare 106.Fig. 7 illustrates another embodiment (SG1), and protrusion 122 is bullet-shaped in this embodiment.Protrusion 122 can move around reliably.In addition, need only carry out Wear-resistant Treatment to the top of protrusion 122 and just can prevent protrusion 122 wearing and tearing.
In addition, according to the foregoing description, an end of column 104 is pounded the limit and is formed incorporate projection 110.Fig. 8 illustrates another embodiment (SG2).That is, can tightly be pressed into an annular element 132 at an end of column 104 and be used as a projection.At this moment, annular element 132 is an individual components; But that will do just is pressed into annular element 132 in the column 104.Therefore, fitting work is still very simple.In addition, leakage of oil can not take place.
In addition, according to the foregoing description, detent mechanism 100 comprises hole portion 102, column 104, ball spare 106 and spring 108.Fig. 9 illustrates another embodiment (SG3).Say that definitely a location mechanism 142 can comprise two parts: one cylindrically has not perforated 144 at an end, and this hole portion 144 is formed on front gear box 46 inside of change speed gear box 10; An and elastic component 146 that inserts in this hole portion 144.
In more detail, as shown in Figure 9, elastic component 146 comprises a flange part 146-1, a butting section 146-2 and a jut 146-3 who makes one.Flange part 146-1 extends on the periphery of elastic component 146.It is inner and all the time against hole portion 144 that butting section 146-2 is positioned at flange part 146-1.Jut 146-3 stretches and against reverse gearwheel driving lever 96 inwards from butting section 146-2.
This embodiment makes the exterior clutch chamber of gear transmission not be communicated with gear transmission in-to-in gear chamber, thereby can leakage of oil, and this helps actual use.In addition, 142 of detent mechanisms are made of hole portion 144 and elastic component 146.This feature makes that component count reduces, cost reduces, thereby more economical.In addition, because fitting work just elastic component 146 patchhole portions 144, therefore assembles and simplifies.
In addition, the following describes front gear box 46.As shown in Figure 9, the width of front gear box 46 " W " can reduce, thereby the volume of whole gear transmission can reduce.
In addition, according to the foregoing description, cylindrical have not perforated 102 at the end to be formed on front gear box 46 inside; In the column 104 patchhole portions 102, thereby form detent mechanism 100.But also available any other structure makes the exterior clutch chamber of gear transmission not be communicated with gear transmission in-to-in gear chamber.Figure 10 illustrates such example (SG4).That is, front gear box 46 has a perforated portion 152.In addition, a column 156 has a flange part 154.The cross-sectional plane of this column 156 takes the shape of the letter U.This column 156 is inserted in the perforated portion 152, thereby constitutes detent mechanism 158.
The same with first embodiment, a ball spare (not shown) and a spring (not shown) are arranged in the column 156.In addition, column 156 also has a projection.
Therefore, need only be just making the exterior clutch chamber of gear transmission no longer be communicated with in the column 156 insertion perforated portions 152 with gear transmission in-to-in gear chamber.This feature is convenient to making, designs simplification, cost reduction, thereby more economical.
