Definitions
- the invention relates to an electrically drivable rail vehicle, for example Low-floor tram, with at least one four-wheeled bogie Frame on which wheels from an electric motor via a drive shaft, a clutch and a gear can be driven, the motor and the drive shaft in the direction of travel and in the area between two wheels of the frame arranged one behind the other Are arranged essentially laterally on the outside of the same.
- An electric vehicle of the type cited above is known from EP-A-0 364 847. With this Electric vehicle, the wheels of motors are driven via drive shafts, the Motors with the respective drive shafts in the direction of travel and in the area between two wheels of the bogie lying one behind the other, but essentially laterally the same are arranged.
- This known electric vehicle has for the parallel wheels continuous axles on, so that a height construction for a low-floor rail vehicle not possible.
- DE-A1-3144999 describes such a drive for rail vehicles, for example:
- An electric motor attached to a bogie drives one via a gearbox continuous transverse axis, at the ends of which a wheel is attached. Therefore, for two driven wheels only one motor necessary, which, however, disadvantageously between the Wheels is under the floor of the rail vehicle.
- Both the transverse axis and the engine also requires a relatively high minimum distance from the vehicle floor from the rails.
- a drive of a rail vehicle can be seen in which a single wheel by means of a synchronous motor, which is on the outside of the Single wheel is arranged, is driven.
- This synchronous motor is designed that the stator is rigid with a fixed axis of the single wheel is connected, while the external rotor is connected to the single wheel Connected screws and is rotatably mounted on the axis with this.
- a cross axis can be omitted, however, so that the vehicle floor between two Wheels or between the rails can be lowered.
- a drive from at the same time two wheels by a single motor is disadvantageously not possible. In order to get enough traction, this has to be done for everyone A separate motor can be provided for the wheel.
- EP-A1-413337 and EP-A1-463168 also describe comparable solutions comparable advantages and disadvantages.
- the used motors a small volume, but also one bring low drive power with it.
- COBRA Commercially-known vehicle
- motors extending in the direction of travel of the vehicle are provided, which have a gearbox on the engine and a cardan shaft each a gearbox, each with rigidly coupled to a wheel.
- This is a very complex structure in itself maintenance-intensive with regard to the cardan drives and expensive with regard to the gears and wide, so that even with this construction there is no optimal width Interior passage lights results.
- none can with this relatively bulky structure Four-wheel bogie can be used, giving its advantages such as Impact reduction on the vehicle body on uneven rails or the like not effective come.
- the invention has for its object an electrically operated To create a vehicle with high drive power per engine, in which the light Clearance inside the vehicle is affected as little as possible by the engines, the focus is accordingly low and the known advantages of a bogie Should find application.
- the invention is intended be made possible to drive two wheels per motor at the same time. The disadvantages mentioned should be avoided as far as possible.
- the Wheels as known per se, are constructed or mounted as idler gears and each have one elastic coupling are connected to the associated transmission, which via a Gear coupling is essentially rigidly connected to the associated motor.
- the known advantage of bogies is in contrast to conventional ones Maintain solutions, whereby the bogie is of course preferred to keep the structure is that it is lower in the area of the vehicle floor than, for example, in the area the bearings and the wheels.
- the use of a single wheel bogie according to the invention also brings compared to the frequently practiced portal frame design, the advantage that the wheels have a have good guidance in the bogie frame and stable running results.
- the Noise is reduced, as is wheel rim wear, and that Improved cornering, with the bogie opposite if necessary the vehicle body also in a plane approximately perpendicular to the direction of travel can be.
- the invention also creates the possibility of two Allowing wheels to be driven by a motor at the same time, without being expensive
- gearbox or cardan solutions for example if at least two Drivable wheels lying one behind the other simultaneously with one continuous motor shaft as the drive shaft of a single motor over one each Gearbox are in drive connection.
- the motor is now at a location where it is different Facilities such as Door mechanisms etc. do not bother. Nevertheless, it can do optimally cooled (e.g. water cooling), which increases its power density.
- optimally cooled e.g. water cooling
- a cone (tooth) wheel gearbox is recommended as a gearbox, this like mentioned is elastically coupled to the (respective) wheel according to the invention.
- This clutch reduces engine and transmission loads and saves on the other hand the use of gimbals for which on a bogie due to the relatively short wheelbase there would be no space.
- the smoothness and Noise minimization is further improved when the clutch is vibration-damped between the gearbox and the associated wheel, so that jerky torques from the engine or the wheel are reduced and damped are transmitted, and / or that mass vibrations of the drive part (motor and gear) are reduced to the wheel.
- Variants are also within the scope of the invention, in which the transmission with a Axle or with an axle stub drivingly connected via the coupling, provided that at least one wheel with this axle or with this stub axle is rigid connected is.
- the preferred elastic attachment of the motor to the bogie reduces in Association with the elastic couplings between gear and wheel undesirable Actions between these components.
- the structure according to the invention allows advantageous further development, according to at least one between the motor and the driven wheel Braking device is arranged, which in the braking state directly or indirectly the drive shaft works. It can e.g. around a shoe brake, Disc brake or the like act. Due to their good effectiveness at high They can build speeds (engine speed) particularly small, light and cheap. you Use between gearbox and motor allows a maximum of integrated compact Construction.
- the brake is there on a well ventilated and closed cooling place.
- mechanical ones are also Brakes directly on the wheel or on and parallel to the wheel connected brake disc possible.
- a comfortable wheelbase with little stress (wear and tear) during Cornering results in a distance between the axes of rotation of the wheels in a row from approx. 180 to 200 cm.
- a compact rail vehicle results when two bogies are used preferably four wheels are provided, the structure of the Rail vehicle between the two bogies at least one joint for has improved cornering.
- the transport performance can be increased economically.
- the invention includes variants with motors on each side of one Electric vehicle or variants with motors only on one side of the Vehicle.
- FIG. 1 illustrates: On a bogie 7 provided according to the invention, the more or is less rotatably connected to the vehicle body are via elastic silent blocks 15 a-c motors 3a, b laterally attached. They each drive a gear 5a, b and 5c, d two wheels 2a, b and 2c, d each.
- the motor or drive shaft 4a, 4b of the Motors 3a, 3b are designed to protrude on both sides.
- a variant with short protruding on one or both sides Shaft pieces with one-sided or two-sided gear coupling via one type Gear coupling or the like. It is also conceivable to have two motors in a row to be provided so that an apparently continuous drive shaft between the Engines is disconnected.
- the drive shafts also each carry a symbolically indicated one Braking device 9a, 9b, e.g. a disc brake.
- the gears 5a-d are with the wheels 2a-d via symbolically indicated elastic Couplings 8a-d connected to both three-dimensional vibrations as well To cushion torque fluctuations.
- a rail vehicle 10a, b according to Fig. 3,4 has three vehicle sections 12a-c, 12d-f, which are interconnected via joints 11a, b and 11c, d, respectively.
- the Joints serve the curve suitability of the rail vehicles 10a, b.
- the sections If necessary, 12b and 12e are via non-driven wheels 2e, f and 2d, h, respectively Rails 13 supported. But it could also be individually driven wheels.
- the top edge of the vehicle floor is e.g. at 30cm above the rail level.
- Gear coupling (17) can be provided.
