Abstract
Disclosed is a motor vehicle running apparatus, comprising a frame provided with a running wheel, and a reduction box and a motor body which are arranged upon the frame, wherein the output shaft of the motor body extends into the reduction box; the reduction box is provided with a locating slot at one side adjacent to the motor body; the motor body is provided with a locating boss which, arranged upon the outer wall of the front side end cover adjacent to the reduction box, is matched to the locating slot; and the locating boss is inserted into the locating slot. The motor vehicle running apparatus of the utility model effectively simplifies the installing operation of the motor body by changing the installing and cooperating structure of the reduction box and the motor body. Moreover, the motor vehicle running apparatus effectively ensures the coaxiality of the output shaft of the motor body and the internal main shaft of the reduction box. In addition, the production quality is improved and the anti-shaking performance during the operating process is also improved.
Description
Technical field
The utility model belongs to electric locomotive structure-design technique field, is specifically related to a kind of electric locomotive running gear.
Background technology
Present colliery electricity consumption locomotive running gear device deficiency below existing aspect the connecting of motor and reduction box: motor mounting is on carriage, and carriage is connected with reduction box with bolt.Motor adopts shaft coupling (two half a couplers, elastomer block in the centre) with connecting of reduction box.Half a coupler is with the mode of bolted; Rely on that extruding comes transfer torque between bolt and the bolt hole wall, the maximum deficiency of this kind connecting mode is that the motor when installing is adjusted with the precision of the axiality of reduction box, and it is spool high often to adopt the mode of shimming to adjust; Enlarge the motor installing hole and adjust axiality etc.; The adjustment difficulty is high, and installation accuracy is difficult to guarantee that the shock resistance that electric locomotive is in operation is also relatively poor.
Summary of the invention
The purpose of the utility model provides that a kind of assembly technology is comparatively simplified and the comparatively accurate electric locomotive running gear of installing and locating.
The technical scheme that realizes the utility model purpose is: a kind of electric locomotive running gear comprises the framework that is provided with travelling wheel and is arranged on reduction box and the motor body on the framework; The output shaft of said motor body stretches in the reduction box; Said reduction box is provided with location notch at the side with the motor body adjacency; Said motor body with the outer wall of the front side end cap of reduction box adjacency on be provided with the positioning boss that matches with this location notch; Said positioning boss is inserted in the location notch.
In the such scheme, said location notch be shaped as circle, the periphery wall of said positioning boss also is circular.
In the such scheme, said framework is provided with bracing frame, and the diapire of said motor body is fixed on this bracing frame.
The utlity model has positive effect: (1) the utility model is through changing the installation fit structure of reduction box and motor body; Thereby effectively simplify the fitting operation of motor body; And can effectively guarantee the axiality of motor body output shaft and reduction box inner main axis; Improve product quality, also promoted the anti-seismic performance that electric locomotive is in operation.

Embodiment
(embodiment 1)
Fig. 1 to Fig. 4 has shown a kind of embodiment of the utility model, and wherein Fig. 1 is a kind of structural representation of the utility model; Fig. 2 is a kind of structural representation of running gear shown in Figure 1 after removing motor body; Fig. 3 is a kind of structural representation of motor body in the running gear shown in Figure 1; Fig. 4 is a kind of structural representation of front side end cap in the motor body shown in Figure 3.
Present embodiment is a kind of electric locomotive running gear, sees Fig. 1 to Fig. 4, comprises the framework 1 that is provided with travelling wheel 11 and is arranged on reduction box 2 and the motor body 3 on the framework 1; The output shaft 31 of said motor body 3 stretches in the reduction box 2; Said reduction box 2 is provided with location notch 21 at the side with motor body 3 adjacency; Said motor body 3 with the outer wall of the front side end cap 30 of reduction box 2 adjacency on be provided with the positioning boss 32 that matches with this location notch 21; Said positioning boss 32 is inserted in the location notch 21.
Said location notch 21 be shaped as circle, the periphery wall of said positioning boss 32 also is circular, the external diameter of positioning boss described in the present embodiment 32 is identical with the internal diameter of location notch 21.
Said framework 1 is provided with bracing frame 12, and the diapire 33 of said motor body 3 is fixed on this bracing frame 12.
Present embodiment is through changing the installation fit structure of reduction box and motor body; Thereby effectively simplify the fitting operation of motor body; And can effectively guarantee the axiality of motor body output shaft and reduction box inner main axis to have improved product quality, also promoted the anti-seismic performance that electric locomotive is in operation.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection range of the utility model.
