It is vertical.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of wheeled tractor gearshift, which is changed
Retaining device is not only simple in structure, is small in size, and convenient for manipulation.
In order to solve the above technical problems, a kind of wheeled tractor gearshift of the utility model, leads containing gear lever, gear
Plate, shift fork I and shift fork II, gear guide plate include shift slot, and gear lever is equipped with sphere, and the sphere installation is in support, shift fork I
It is stuck in shift fork II in the annular groove of two balladeur trains, also contains shift fork axle, the left part of shift fork axle is equipped with three gear position rings
Shape slot I, the right part of shift fork axle are equipped with three gear position annular grooves II, and the front of the shift fork I is equipped with sleeve I, the front of shift fork II
Equipped with sleeve II, the front end of the shift fork I is equipped with groove I, and the front end of the shift fork II is equipped with groove II, the gear lever
Middle and lower part is located in groove I or groove II, and the gear lever lower end is located in the shift slot of gear guide plate, the set of the shift fork I
Blind hole I is equipped in cylinder I, blind hole I is sequentially arranged with spring I and steel ball I, what the left part that a part of steel ball I is located at shift fork axle was equipped with
In three gear position annular grooves I, blind hole II is equipped in the sleeve II of the shift fork II, blind hole II is sequentially arranged with spring II and steel ball
II, in the three gear position annular grooves II that the right part that a part of steel ball II is located at shift fork axle is equipped with.
In above-mentioned wheeled tractor gearshift, since shift fork I and shift fork II are sleeved in shift fork axle, with existing skill
Art is compared, and eliminates a shifting block axis, two outer shifting blocks and shifting block, therefore be not only simple in structure, be small in size, and convenient for behaviour
It is vertical.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model wheeled tractor gearshift；
Fig. 2 is the connection relationship structural schematic diagram between gear lever, shift fork I, shift fork II and shift fork axle.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below.
In Fig. 1 and Fig. 2, a kind of wheeled tractor gearshift contains gear lever 3, gear guide plate 7, shift fork I 15 and shift fork
Ⅱ6.Gear guide plate 7 includes shift slot.Gear lever 3 is equipped with sphere 2, which is mounted in support 1.Shift fork I 15 and shift fork
II 6 are stuck in the annular groove of two balladeur trains.Also contain shift fork axle 5, the left part of shift fork axle 5 is equipped with three gear position annular grooves
I 16, the right part of shift fork axle 5 is equipped with three gear position annular grooves II 9.The front of the shift fork I 15 is equipped with sleeve I 17, shift fork II 6
Front is equipped with sleeve II 18.The front end of the shift fork I 15 is equipped with groove I 12.The front end 4 of the shift fork II 6 is equipped with groove
Ⅱ8.3 middle and lower part of gear lever is located in groove I 12 or groove II 8, and 3 lower end of gear lever is located at the gear of gear guide plate 7
In the slot of position.Blind hole I is equipped in the sleeve I 17 of the shift fork I 15, blind hole I is sequentially arranged with spring I 14 and steel ball I 13, steel ball I 13
A part be located in the three gear position annular grooves I 16 that the left part of shift fork axle 5 is equipped with.It is set in the sleeve II 18 of the shift fork II 6
