In the high-speed bogie driving device, the operating environment thereof is changed qualitatively. When the bogie is operated at high speed, a large amount of dust is rolled up, and when the bogie is operated in a windy and sandy area, the bogie is also attacked by a large amount of wind and sand, so that great harm is brought to a bogie driving device, the assembly precision among all parts is correspondingly required to be improved, and a completely closed environment is required to be formed in the chamber and the box body, so that the driving and braking of the bogie are prevented from being influenced by the invasion of the wind and sand.
In the existing bogie driving device, a gear box adopts a central box dividing surface structure, the installation and sealing between an upper box body and a lower box body are difficult to meet the precision requirement, and wind sand easily enters the gear box.
In addition, the coupling is a key component for connecting the driving motor and the gear box, and after the existing coupling is connected with the crowned tooth taper hole and the transmission shaft (comprising the output shaft of the driving motor and the pinion shaft), proper protection is lacked between the outer cylinder of the coupling and the transmission shaft, so that dust and wind sand are easy to enter the coupling to influence the transmission performance of the coupling.
SUMMERY OF THE UTILITY MODEL
Bogie drive arrangement, its design aim at solve above-mentioned problem and adopt and go up the integral gear box of branch case face and shaft coupling outer end protection airtight measure to realize improving the machining precision of key parts such as gear box, improving the sealing performance of the inside cavity of part, prevent the invasion of dust and sand blown by the wind, guarantee rail vehicle's safe high-speed operation.
In order to achieve the above design object, the bogie driving device includes: a gear box, a drive motor, and a crowned tooth flexible coupling. Wherein, the gear wheel of the gear box is arranged on the axle of the bogie;
the axis of the output shaft of the driving motor is parallel to the axis of the bogie axle and is connected with the pinion shaft of the gear box in a collinear way through a crowned tooth flexible coupling.
The improved scheme is that the gear box is of an integral structure with an upper box dividing surface, and an end cover is arranged at the upper part of the box body.
When a train is pulled, the driving motor drives the coupling, the coupling drives the pinion shaft of the gear box, the pinion shaft drives the bull gear, and the bull gear drives the wheel pair to run along the track direction; when a train is braked, the wheel pair drives the large gear, the large gear drives the small gear shaft, the small gear shaft drives the coupling, the coupling drives the driving motor, the driving motor at the moment operates as a generator, and kinetic energy of the train is converted into electric energy to be fed back to a power grid.
The gear box of the driving device can be made of aluminum alloy materials, the weight of the gear box is reduced by about 2/3 compared with the traditional cast iron or cast steel materials, and the weight of a member under a series of springs can be effectively reduced, so that the overall running performance of the railway vehicle is improved.
The gear box adopts the face structure of dividing the case, compares with current center face structure of dividing the case, and integral box can more guarantee the machining precision of key position such as bearing frame, branch case face. Moreover, under the same machining and assembling precision standard, the sealing performance of the upper box dividing surface structure is better, and the invasion of dust and sand wind is easier to prevent.
In order to realize the position adjustment between the center of the pinion shaft of the gear box and the center of the output shaft of the driving motor, the lower end of the gear box suspender is arranged at the lower part of the gear box through a fastening device; the upper end of the gearbox suspender is suspended below the bogie frame through a suspension seat, and gaskets for adjusting the vertical height are respectively arranged above and below the suspension seat.
The lower part of the gear box is fastened, the upper end of the gear box forms a movable end to be hung below the framework, and the position between the center of the pinion shaft and the center of the output shaft of the driving motor can be conveniently adjusted by adjusting the gaskets above and below the hanging seat.
In order to improve the sealing and wind and sand prevention performance of the coupling, a flexible protection plate is embedded between an outer cylinder end cover of the crowned tooth flexible coupling and a transmission shaft, so that a closed space is formed in the coupling, dust, wind and sand and other impurities are prevented from entering the coupling, and the transmission performance of the coupling is ensured.
As described above, the utility model discloses bogie drive arrangement has the advantage be:
1. the improved upper box surface gear box is easier to process parts with high precision and better sealing performance.
2. The position adjustment performance between the gear box and the transmission shaft is improved, and the relative height of the pinion shaft is conveniently adjusted.
3. The sealing and sand-proof performance of the coupling is improved, and the transmission performance of the coupling in a sand-proof environment is effectively improved.
