Abstract
The utility model discloses a power takeoff assembly with a speed changer connected with a rotating shaft, which comprises a power takeoff front case, a power takeoff back case, a power takeoff spline shaft, an input gear shaft, an output gear shaft, a slide sleeve, an output flange, a pulling fork shaft, a spring and a pulling fork, wherein the input gear shaft and the output gear shaft are parallelly arranged in the power takeoff front case and the power takeoff back case, the slide sleeve is sheathed on the input gear shaft through splines, the output flange is fixedly sheathed on the output gear shaft, the pulling fork is used for pulling the slide sleeve, and screw bolt holes which share one axial line and are connected with a speed changer box body are formed on the power takeoff front case and the power takeoff back case. The screw bolt holes which share one axial line and are connected with the speed changer box body are formed on the power takeoff front case and the power takeoff back case, during the installation, a whole power takeoff can be directly arranged on the speed changer box body, the dismounting and the separation are not needed, and the fault rate of the power takeoff can be reduced. Because the power takeoff is integrally installed, the single preservation of an installation hole position of the power takeoff front case is not needed, the size of a casing can be reduced, the weight of the whole body can be reduced, the cost is low, and meanwhile, the production processing and assembling beat is faster.
Description
Technical field
The utility model relates to a kind of vehicle power transmission mechanism, relates in particular to the power takeoff assembly that a kind of change-speed box switches through moving axis.
Background technology
Power takeoff on the change-speed box is to be used for running car engine power in addition to supply with, and for example the rear platform of self-unloading truck is supplied with power with power takeoff and realized self-unloading.Power takeoff drives additional equipment, such as the crane that drives oil pump, and tip lorry, concrete mixer, the water truck of drive water pump, the suction-type sewer scavenger of band vacuum pump etc.
The power takeoff assembly structure that change-speed box of the prior art switches through moving axis as shown in Figure 1, 2.The power takeoff assembly that change-speed box switches through moving axis comprises power takeoff fore shell 1a, power takeoff back cover 2a, power takeoff castellated shaft 3a, be set in parallel in input gear axle 4a in power takeoff fore shell 1a and the power takeoff back cover 2a and output gear shaft 5a, by the sliding sleeve 6a of spline package on input gear axle 4a, fixed cover on output gear shaft 5a output flange 7a, declutch shift shaft 8a, spring 9a and be used to stir the shift fork 10a of sliding sleeve 6a.Power takeoff fore shell 1a is provided with and mission case bonded assembly bolt hole, and is provided with on power takeoff back cover 2a and power takeoff fore shell 1a bonded assembly bolt hole 11a, and the bolt hole on power takeoff fore shell 1a and the power takeoff back cover 2a is not on same axis.
Mainly there is following deficiency in the power takeoff assembly that the change-speed box of said structure switches through moving axis: one, install inconvenient, at first need during installation down the dismounting of power takeoff back cover, the power takeoff fore shell is installed on the mission case, then the power takeoff back cover could be installed, the back is installed like this compares, will cause the fault rate of power takeoff to increase with the original-pack of power takeoff; Two, because of the power takeoff fore shell for being arranged separately on the mission case, need stay the installation position of power takeoff fore shell, cause the housing volume of power takeoff to increase, quality is heavy, cost up; Three, because the power takeoff dismounting need be carried out secondary assembling, so production and processing, assembling beat are slower.
The utility model content
At the prior art above shortcomings, need not to split just direct mount but the utility model provides a kind of, and the housing volume is little, in light weight, cost is low, production and processing simultaneously, assembling beat change-speed box faster switches through the power takeoff assembly of moving axis.
The change-speed box that the utility model provides switches through the power takeoff assembly of moving axis, comprise power takeoff fore shell, power takeoff back cover, power takeoff castellated shaft, be set in parallel in input gear axle in power takeoff fore shell and the power takeoff back cover and output gear shaft, by the sliding sleeve of spline package on the input gear axle, fixed cover on output gear shaft output flange, declutch shift shaft, spring and be used to stir the shift fork of sliding sleeve; Described power takeoff fore shell and power takeoff back cover be provided with same axis and with mission case bonded assembly bolt hole.
Compared with prior art, the change-speed box of the present utility model power takeoff assembly that switches through moving axis has following advantage:
1, power takeoff fore shell and power takeoff back cover be provided with same axis and with mission case bonded assembly bolt hole, during installation, can directly whole power takeoff be installed on the mission case, need not to split, can reduce the fault rate of power takeoff.
2, because power takeoff is integral installation, need not to stay separately the mounting hole site of power takeoff fore shell, can dwindle the volume of housing, overall weight is light, and cost is low.
3, production and processing simultaneously, assembling beat are faster.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail.
Fig. 3 switches through the front view of the power takeoff assembly of moving axis for the utility model change-speed box, and Fig. 4 is along the cross section view of B-B direction, as shown in the figure among Fig. 3.The power takeoff assembly that change-speed box switches through moving axis comprises power takeoff fore shell 1, power takeoff back cover 2, power takeoff castellated shaft 3, be set in parallel in input gear axle 4 in power takeoff fore shell 1 and the power takeoff back cover 2 and output gear shaft 5, by spline package the sliding sleeve on the input gear axle 46, fixed cover on output gear shaft 5 output flange 7, declutch shift shaft 8, spring 9 and be used to stir the shift fork 10 of sliding sleeve 6; Power takeoff fore shell 1 and power takeoff back cover 2 be provided with same axis and with mission case bonded assembly bolt hole 11.
When this change-speed box being installed switching through the power takeoff assembly of moving axis, bolt hole on the power takeoff housing 11 is corresponding with bolt hole on the mission case, bolt directly passes the bolt hole on power takeoff back cover 2, power takeoff fore shell 1 and the mission case, again by the fastening nut lock bolt, so just whole power takeoff is installed on the mission case, easy for installation, quick.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
