Description
Technical field
The utility model relates to a kind of wheeled tractor, especially a kind of wheeled tractor hand brake device.
Background technique
A kind of existing wheeled tractor, including gearbox, hand brake device, front axle assy and rear axle assy.Gearbox
Interior includes axis, axisIt is equipped with driving gear, driving gear is engaged with driven gear, and driven gear is arranged in preceding driving transmission shaft
On, preceding driving transmission shaft is arranged on the cabinet of gearbox by bearing.Hand brake device include control crank component, connecting rod,
Brake cam, rocker arm, shaft, axle bed, steel disc, friction plate component, pressing plate and pressing plate seat.Steel disc and friction plate component are sleeved on change
Axis in fast caseOne end on.Since steel disc and friction plate component are sleeved on the axis in gearboxOne end on, increase axis
Length, therefore result in gearbox cabinet lengthen, so that the volume of gearbox be made to become larger, increase production cost.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of wheeled tractor hand brake device, the wheeled tractors
Hand brake device can make the box deformation of gearbox small, to reduce production cost.
In order to solve the above technical problems, a kind of wheeled tractor hand brake device of the utility model, is arranged on gearbox,
It include axis in gearbox, axisIt is equipped with driving gear, driving gear is engaged with driven gear, and driven gear is arranged in forerunner
On dynamic transmission shaft, preceding driving transmission shaft is arranged on the cabinet of gearbox by bearing, and the hand brake device includes manipulation hand
Handle component, connecting rod, cam, rocker arm, shaft, axle bed, steel disc, friction plate component, pressing plate and pressing plate seat, steel disc and friction plate component
Driving transmission shaft one end is on splined shaft before being successively sleeved on, and pressing plate seat is arranged on the inner wall of gearbox, and pressing plate is mounted in pressure
On the stud of panel seat, and pressing plate can move on stud, and pressing plate is located at the outside of friction plate component, and shaft is mounted on axle bed,
Axle bed is arranged on the inner wall of gearbox, and cam is arranged in shaft, and cam is located at the outside of pressing plate, and one end setting is turning
On axis, the other end of rocker arm is connected with one end of connecting rod, and the other end of connecting rod is connected with control crank component, control crank component
It is arranged on gearbox.
In above-mentioned wheeled tractor hand brake device, since steel disc and friction plate component are successively sleeved on preceding driving transmission
Axis one end is therefore axis on splined shaftLength can shorten, to keep the box deformation of gearbox small, reduction is produced into
This.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model wheeled tractor hand brake device.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below.
In Fig. 1, a kind of wheeled tractor hand brake device is arranged on gearbox 4, includes axis in gearbox 412, axis12 are equipped with driving gear 11, and driving gear 11 is engaged with driven gear 10, and driven gear 10 is arranged in preceding driving transmission shaft 9
On.Preceding driving transmission shaft 9 is arranged on the cabinet of gearbox 4 by bearing.The hand brake device includes control crank component
1, connecting rod 2, cam 7, rocker arm, shaft 8, axle bed, steel disc 3, friction plate component 5, pressing plate 6 and pressing plate seat.Steel disc 3 and friction plate close
Driving 9 one end of transmission shaft is on splined shaft before part 5 is successively sleeved on.Pressing plate seat is arranged on the inner wall of gearbox 4, pressing plate 6
On the stud of pressing plate seat, and pressing plate 6 can move on stud.Pressing plate 6 is located at the outside of friction plate component 5.Shaft 8 fills
On axle bed, axle bed is arranged on the inner wall of gearbox 4, and cam 7 is arranged in shaft 8, and cam 7 is located at the outside of pressing plate 6.It shakes
Arm one end is arranged in shaft 8, and the other end of rocker arm is connected with one end of connecting rod 2, the other end and control crank component of connecting rod 2
1 is connected.Control crank component 1 is arranged on gearbox 4.
When needing to brake, control crank component 1 is manipulated, connecting rod 2 drives rocker arm to rotate shaft 8,8 band of shaft of rotation
Moving cam 7 rotates, and the cam 7 of rotation pushes pressing plate 6 to move inward, and pressing plate 6 compresses friction plate component 5 and steel disc 3, before making
Drive transmission shaft 9 static, at this moment axis12 also stop operating, to realize braking.
In above-mentioned wheeled tractor hand brake device, since steel disc 3 and friction plate component 5 are successively sleeved on preceding driving and pass
9 one end of moving axis is not occupy exceptional space, therefore axis on splined shaft12 length can shorten, to make gearbox 4
Box deformation is small, compact-sized, reduces production cost.
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model
The utility model processed, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done,
It should be included within the scope of protection of this utility model.
