Specific implementation mode
The utility model is described in further detail below in conjunction with Figure of description, and provides specific implementation mode.
Referring to Fig.1, a kind of power take off of speed change, including shell 1, input unit, slave unit, manipulation device, institute
It includes input shaft 2, input gear group to state input unit, and the slave unit includes the output shaft 5 with external splines and carries interior flower
The driven gear group of key, the manipulation device include control stick, self-locking mechanism, limited cover 14, and the input unit passes through input
Axis 2 is fixed on shell 1, and the slave unit is connected to by output shaft 5 on shell 1.There are two teeth for the driven gear group
Wheel includes the connecting bridge 8 of preceding driven gear 6, rear driven gear 7, connection preceding driven gear 6 and rear driven gear 7.It is described defeated
Enter gear set there are two gear, including driving gear 3, input gear 4, the input gear 4 is by bearing holder (housing, cover) in input shaft 2
On, the driving gear 3 is fixedly arranged at by key on input gear 4.The diameter of driving gear 3 is less than the diameter of input gear 4, can
It is engaged with driven gear before realization 6 and driving gear 3, rear driven gear 7 and input gear 4 engage.The diameter of preceding driven gear 6
It is greater than rear driven gear 7, when the rotating speed of input is the same, the diameter of above-mentioned two gear is different, driven gear 6 before institute
It is engaged respectively with input gear group with rear driven gear 7, the speed of output is different.
With reference to Fig. 2, control stick includes manipulating mobile jib 9, shift fork 10, positive stop lug boss 11, rocking arm 12, and the shift fork 10 is installed on
Manipulate mobile jib 9 lower end, rocking arm 12 be installed on manipulate mobile jib 9 upper end, positive stop lug boss 11 manipulate mobile jib 9 centre, it is described
11 intermediate finite position hole 18 of positive stop lug boss.With reference to Fig. 4, limiting slot 19 is offered on the limited cover 14.With reference to Fig. 3, it is described from
Latch mechanism includes the self-locking hole 15, spring 17, ball 16 being opened on shell, and the spring 17 is placed in the self-locking hole on shell
In 15, ball 16 is connected on spring 17.9 through hole of manipulation mobile jib passes through shell 1, and positive stop lug boss 11 is with lower part position
In in shell, shift fork 10 is stuck among driven gear group, and positive stop lug boss 11 covers on shell 1, covers self-locking mechanism, limited cover
14 be through manipulate mobile jib 9 on cover positive stop lug boss 11, positive stop lug boss 11 is located in the limiting slot 19 of limited cover 14, limited cover 14 lead to
Bolt is crossed to be fixed on shell 1.
According to the above, the implementation of control stick has the following steps：First, the rocking arm 12 in control stick and manipulation mobile jib 9
In a plane, mobile jib 9 and shift fork 10 are manipulated in another plane.Two planes recited above are orthogonal, so shaking
When the drive of arm 12 manipulates mobile jib 9 clockwise or counterclockwise, shift fork 10 can moved accordingly clockwise or counterclockwise.Its
It is secondary.Limited cover 14 is equipped with limiting slot 19, and positive stop lug boss 11 is assemblied in limiting slot 19, and rocking arm 12, which drives, manipulates the rotation of mobile jib 9
When, it is assemblied in the space for manipulating the positive stop lug boss 11 on mobile jib 9 because of limiting slot 19, defines the movement model of positive stop lug boss 11
It encloses, because 11 motion range of positive stop lug boss is limited, manipulates the angle that mobile jib 9 rotates and be limited, the rotating range of rocking arm 12 is also corresponding
It is restricted.It is a gear that rocking arm 12, which is rotated clockwise to the limit, and it is another gear to rotate counterclockwise to the limit.Most
Afterwards, self-locking mechanism, compressed spring, positive stop lug boss 11 can all be covered as long as positive stop lug boss 11 moves in the space of limiting slot 19
Without gap between 1 contact plane of shell, only when the ball 16 for being moved to limit hole 18 and self-locking mechanism coincide, because having
The space of limit hole 18, spring bounce, and so that ball 16 is entered in limit hole 18, play the role of locking, at this moment, entirely take
Power device is in neutral gear position.
Referring to Fig.1, the shift fork 10 is stuck in the connecting bridge 8 of driven gear group.Preceding driven gear is stirred in the realization of shift fork 10
6 make driven gear group travel forward, and can stir rear driven gear 7 makes driven gear group move backward.
It is to sum up told, when rocking arm 12 rotates counterclockwise, shift fork 10 stirs rear driven gear 7 and input gear 4 engages, power taking
Device exports a kind of speed.When rocking arm 12 rotates clockwise, driven gear 6 and driving gear 3 engage before shift fork 10 is stirred, power takeoff
Another speed of output.When rocking arm 12 is in neutral position state, self-locking mechanism works, and power takeoff is in off working state.Shift fork
When 10 driving driven gear group, the movement locus of shift fork 10 is a circular arc, and different from other power takeoffs with drive shaft, band drives
The track that the movement locus of the power takeoff shift fork of moving axis is engaged or detached with driven gear is equidirectional.
The utility model realizes the power takeoff of two speed outputs, reduces requirement of the assembling structure to power source, structure letter
It is single, without others auxiliary device, it is easy to accomplish, the requirement to installation space is small.
Finally illustrate, above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to this
The technical solution of utility model is modified or replaced equivalently, without departing from the objective and model of technical solutions of the utility model
It encloses, should all cover in the right of the utility model.
