Description
Technical field
The utility model relates to the hinged motor train unit bogie technical field of low floor, particularly relates to the hinged motor train unit bogie of a kind of low floor and drives and brake equipment.
Background technology
The hinged motor train unit of low floor for short-distance passenger transportation are because its passenger capacity is large, the development tendency that becomes Eurocities suburbs rail transport compared with advantages such as Automobile Transportation safety, passenger getting on/off convenience, environmental protection.But domesticly also do not grasp the hinged motor train unit technology of low floor at present, mainly because hinged motor train unit bogie technical sophistication, realize low floor and just more difficult for.And the actuating device in bogie structure and brake equipment are the gordian techniquies that can realize low floor.
Utility model content
Goal of the invention of the present utility model is the blank filling up the hinged motor train unit bogie truck driving of domestic low floor and braking technology, domestic platform height is generally 1000mm ~ 1250mm, adopt this actuating device and brake equipment, floor level can be down to 550mm ~ 750mm, facilitate passenger getting on/off, reduce line project cost.
To achieve these goals, the technical scheme taked of the utility model is as follows:
The hinged motor train unit bogie of a kind of low floor drives and brake equipment, comprises traction electric machine, gear system, brake disc and brake unit; It is characterized in that: the diameter of traction electric machine is not more than 500mm, the height that traction electric machine end face exceedes axletree is not more than 200mm, and traction electric machine hangs on truck frame by four metal-rubber articulated liftings, above traction electric machine and axletree, be provided with safety stop; Gear system adopts double reduction gear box structure, and the height that gear case end face exceedes axletree is not more than 200mm, and the height that vertical gear case suspension rod summit exceedes axletree is simultaneously not more than 200mm; Gear case is provided with safety stop, and gear case is connected with traction electric machine by coupler, and is arranged on together inside framework; Brake disc is arranged on wheel, and brake unit is arranged in wheel to outside, is symmetrically distributed in bogie truck end, and each brake unit is hung architecturally by four suspension centres, is provided with height adjusting block between brake unit and framework.
The beneficial effects of the utility model are as follows:
1) traction electric machine adopting external form elongated, the height that its end face exceedes axletree is not more than 200mm, provides space for car body floor face reduces.
2) height that gear case end face exceedes axletree is not more than 200mm, and the height that vertical gear case suspension rod summit exceedes axletree simultaneously is also not more than 200mm, ensure that there are enough reduction spaces in car body floor face.
3) brake unit is arranged in wheel to outside, reduces the setting height(from bottom) of brake unit, is also convenient to the maintenance and repair of brake unit, reduces maintenance and repair cost.
4) be provided with height adjusting block between brake unit and framework, different floor levels can be adapted to, for the reduction of floor provides space.
