Description

Adopt the engine truck of motor-hollow axle wheel to actuating device
Technical field
The utility model relates to engine truck technical field, and especially a kind of motor-hollow axle that adopts takes turns engine truck to actuating device.
Background technology
Because the vibration between high-speed locomotive steering frame motor and gear pair is comparatively large, be unfavorable for the transmission of moment of torsion, easily gear pair and motor shaft produced and impact, affect its service life.In order to address this problem, domestic existing engine truck all adopts the mounting structure of hollow axle wheel set actuating device.This structure needs to increase the assembling of a set of hollow shaft in the outside of axletree, increases wheel like this to driving the space taken, and makes to take turns and strengthens the width between centers between motor, add the length of bogie truck.Be unfavorable for that space is arranged, the weight that also add, is unfavorable for light-weight design.
Utility model content
In order to the width between centers overcome between existing steering framing wheel pair and motor strengthens, add the deficiency of the length of bogie truck, the utility model provides a kind of motor-hollow axle that adopts and takes turns engine truck to actuating device.
The utility model solves the technical scheme that its technical matters adopts: a kind of motor-hollow axle that adopts takes turns engine truck to actuating device, comprise framework, described framework is provided with draw gear, it is right to take turns actuating device, disc brake and wheel, described wheel is provided with motor shaft in actuating device, on described motor shaft, cover has hollow shaft, described hollow shaft is connected with plunging joint, and described plunging joint is connected with gear case.
According to another embodiment of the present utility model, comprise further, described gear case by the gear pair in its casing with take turns being connected.
According to another embodiment of the present utility model, comprise further, described hollow shaft lower end is connected with plunging joint by diaphragm.
The beneficial effects of the utility model are, the engine truck of this employing motor-hollow axle wheel to actuating device, its structure can meet the operation needs of high-speed locomotive steering frame, this bogie truck reduces vibration and the impact of gear pair, improve the operation environment of gear, thus extend the life-span of gear, and structure is simple, reliability is strong, is conducive to the light-weight design realizing bogie truck.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure 1, framework, 2, draw gear, 3, take turns actuating device, 4, disc brake, 5, hollow shaft, 6, motor shaft, 7, plunging joint, 8, gear case, 9, take turns right.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of motor-hollow axle that adopts takes turns engine truck to actuating device, comprise framework 1, described framework 1 is provided with draw gear 2, takes turns actuating device 3, disc brake 4 and wheel 9, described wheel is provided with motor shaft 6 in actuating device 3, on described motor shaft 6, cover has hollow shaft 5, and described hollow shaft 5 is connected with plunging joint 7, and described plunging joint 7 is connected with gear case 8.
According to another embodiment of the present utility model, comprise further, described gear case 8 is connected 9 with wheel by the gear pair in its casing.
According to another embodiment of the present utility model, comprise further, described hollow shaft 5 lower end is connected with plunging joint 7 by diaphragm.
The engine truck of this employing motor-hollow axle wheel to actuating device, wheel exports from motor shaft 6 moment of torsion of the motor of actuating device 3, hold (i.e. figure hollow mandrel 5 upper end) to be connected with the A of hollow shaft 5, be delivered on hollow shaft 5, then be connected with diaphragm type plunging joint 7 by B end (i.e. figure hollow mandrel 5 lower end), thus be delivered on the gear pair in gear case 8, be finally delivered to wheel on 9.
In order to adapt to demand at a high speed, this bogie truck is provided with the motor of hollow shaft 5 structure, and moment of torsion is delivered to gear case 8 again from motor output end (A end) output and inputs (B end), is different from conventional motors and directly outputs on gear case 8 at B end.By increasing transmission length, making the Oscillation Amplitude of motor output end (A end) be delivered to gear case 8 and inputting (B end) time and weaken widely.Significantly can reduce Relative Vibration under High Rotation Speed state of motor and gear pair and impact, make moment of torsion transmission more stable, reduce the probability that Gear Contact planar defect produces, improve the operation environment of gear, thus extend the life-span of gear.
Plunging joint 7 adopts diaphragm type transmission, adapts to the high-revolving demand of the low moment of torsion of typotron.
Hollow shaft 5 is set in motor, shortens the length of taking turns the width between centers between motor and bogie truck, be conducive to space and arrange, achieve the light-weight design of bogie truck.
Bogie truck motor is rigid suspended on framework 1, reduces the unsprung weight of bogie truck wheel-rail impact.
Actuating device adopts the rigid suspended and diaphragm type plunging joint 7 of motor, and structure is simple, and reliability is strong.
Multiple disc brake can meet the brake request in speed car.
