Model utility content
The purpose of this utility model is for above-mentioned the problems of the prior art, provides a kind of structure simple, the scope gear cylinder stopper mechanism of reliable performance.
To achieve these goals, the technical solution adopted in the utility model is: comprise and complementing one another and all pneumatic cylinder of tool and cylinder head, cylinder and cylinder head offers the first inlet hole respectively and the second inlet hole makes air cavity and ft connection; Arrange piston in the air cavity of cylinder, piston is connected with declutch shift shaft, and the declutch shift shaft the other end of cylinder outside connects shift fork; Described declutch shift shaft offers several grooves, cylinder installs hollow bolt, hollow bolt inside arranges Compress Spring, Compress Spring head rest supporting has the place kick with fit depressions, when moving under the drive of declutch shift shaft at piston, place kick falls into corresponding groove, and under the elastic force effect of Compress Spring, realize location stopper.
Described Compress Spring diameter is equal with the inner aperture of hollow bolt.
The groove that described declutch shift shaft is offered is ball-type groove or circular groove.
The corresponding high gear air inlet of described groove and low gear air inlet are provided with two.
The corresponding high gear air inlet of described groove, middle apron air inlet and low gear air inlet are provided with three.
Described place kick is steel ball.
The first described inlet hole is communicated with bottom the air cavity on cylinder.
Described declutch shift shaft and the connecting end of piston arrange boss, and boss is fixed by nut through piston.
Compared with prior art, the utility model by offering groove on scope gear shifting cylinder declutch shift shaft, and on scope gear shifting cylinder, hollow bolt is installed, the built-in place kick of hollow bolt and Compress Spring, when the gearshift of scope gear is to working position, place kick falls in groove in the elastic force effect of Compress Spring, and then realize stopper, make scope keep off when working position like this, not easily deviate from from gear, ensure that the normal operation of speed changer, thus improve the safety in operation of vehicle.The utility model structure is simple, reliable performance.
Further, the utility model Compress Spring diameter is equal with the inner aperture of hollow bolt, by means of hollow bolt endoporus and limit Compress Spring activity direction, and then declutch shift shaft is when moving, place kick can not drive Compress Spring to swing, and improves reliability when device uses.
Accompanying drawing explanation
The cylinder gearshift structural representation of Fig. 1 traditional range shift transmission;
Fig. 2 overall structure schematic diagram of the present utility model;
In accompanying drawing: 1. declutch shift shaft; 2. cylinder; 3. piston; 4. nut; 5. cylinder head; 6. shift fork; 7. bolt; 8. the first inlet hole; 9. the second inlet hole; 10. hollow bolt; 11. Compress Springs; 12. place kick; 13. grooves.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, the cylinder gearshift of traditional range shift transmission, one end fitting limit gear cylinder piston 3 of declutch shift shaft 1, and fix with nut 4, the other end fitting limit gear cylinder selector fork 6, and fix with bolt 7; Meanwhile, scope gear shifting cylinder 2 and scope gear shifting cylinder lid 5 are processed with the first inlet hole 8 and the second inlet hole 9 respectively.After inputting the gas of certain air pressure from the first inlet hole 8 or the second inlet hole 9 respectively, scope gear cylinder range piston 3 under the influence of air pressure, corresponding position is moved to by scope gear selector fork axle 1 sphere of driving gear cylinder selector fork 6, transmission range is kept off and is linked into required gear, to realize the fundamental function of transmission range gear gearshift.
See Fig. 2, the utility model comprises and complementing one another and all pneumatic cylinder 2 of tool and cylinder head 5, cylinder 2 and cylinder head 5 offer the first inlet hole 8 respectively and the second inlet hole 9 makes air cavity and ft connection, wherein the first inlet hole 8 is communicated with bottom the air cavity on cylinder 2; Arrange piston 3 in the air cavity of cylinder 2, piston 3 is connected with one end of declutch shift shaft 1, and declutch shift shaft 1 arranges boss with the connecting end of piston 3, and boss is fixed by nut 4 through piston 3.Declutch shift shaft 1 the other end of cylinder 2 outside connects shift fork 6; Declutch shift shaft 1 offers several grooves 13, groove 13 is ball-type groove or circular groove, cylinder 2 is installed hollow bolt 10, hollow bolt 10 inside arranges Compress Spring 11, Compress Spring 11 diameter is equal with the inner aperture of hollow bolt 10, Compress Spring 11 head rest supporting has the place kick 12 matched with groove 13, and place kick 12 is steel ball.When declutch shift shaft 1 moves under the drive of piston 3, place kick 12 falls into corresponding groove 13, and under the elastic force effect of Compress Spring 11, realize location stopper.Wherein, if the corresponding high gear air inlet of groove 13 and low gear air inlet are provided with two, if the corresponding high gear air inlet of groove 13, middle apron air inlet and low gear air inlet are provided with three.
