Description

SYSTEM OF THE AUTONOMOUS POWER SUPPLY OF RAILROAD
CARS OR PLATFORMS DRIVEN BY A WHEEL PAIR AXLE
DESCRIPTION
Prior Art
The claimed technical solution relates to railroad transport and provides an autonomous power supply for cars and / or platforms of the railroad vehicles.
The freight rolling stock performs transportation of a large range of types of goods, including perishable ones. Moreover, in the market of perishable cargo the railroad transport is fiercely competed by the automobile transport. One of the factors that permit reinforcing the position of the railroad transport in this market is modernization of the existing rolling stock - refrigerated rail cars and containers.
A significant proportion of container shipping abroad (up to 70 %) and the integration of Russia into the global market of transport services (in particular, the development of the transport corridor "East-West) create the preconditions for the growth of container traffic in our country.
Containers allow a transportation of various types of goods, including perishable ones. At the same time the transportation of the perishable cargo by means of containers requires
energy- equipped platforms.
The refrigerated rolling stock and the platforms for
transportation of refrigerator containers should have a source of electricity, which may be an undercar generator driven by a wheel pair axle.
"System of the autonomous power supply of railroad freight cars and / or platforms driven by a wheel pair axle" (utility model patent (RU) number 105861, Publ. 27.06.2011, B60L1/00 is known in the art.
The system includes an undercar generator equipped with a shaft mounted on a rigid frame, located in the undercar space and pivotally connected on one side to the frame (center sill) of the car and/or the platform, on the other side, to the wheel pair axle with the ability to allow free rotation of the axle in the rigid frame, and a drive.
The essence of the solution is that the rigid frame is connected to the center sill of the car and/or the platform by a rod with two spherical joints at both ends and to the wheel pair axle with split rubber bushings arranged in the inner cavity of the split hollow shaft, wherein the surface of the split hollow shaft has concentric grooves in which are
installed detachable supports in the form of rollers,
providing the free rotation of the wheel pair axle in the rigid frame on which the undercar generator is mounted.
The system is designed to provide the autonomous
uninterrupted power supply of the cars and / or the platforms from the wheel pair axles of frameless trucks when passing curved tracks.
However, the known solution has a number of essential shortcomings :
- in case of the drive belt failure, in order to install a new belt over the wheel pair axle, it is necessary to roll the car truck out from undercar space to release the wheel pair;
- minimum applicable belt length is dictated by the
necessity of pulling it over the wheel, that increases the length of the generator suspension rigid frame;
- the power transmitted by the belt-and-pulley transmission from the wheel pair axle to the generator is limited by the transmission ratio of the drive and driven pulleys, and
depends on the distance from the wheel pair axle to the track bed structure in the undercar space;
- when the car is empty, it does not require electricity, but the generator will continue to produce it due to the installed drive belts, which will eventually reduce the
service life of the drive and the generator bearings.
The mentioned system and is considered herein as the closest analogue (prototype) . The technical result of the claimed solution is to decrease the dimensions, to increase transmission ratio of the drive along with keeping drooping characteristics thereof, to
increase the service lifetime of the drive and of the
generator bearings by eliminating the idle run, and to ease the device maintainability.
SUMMARY OF THE INVENTION
The technical result is accomplished by the system of the autonomous power supply of railroad mainly freight cars and/or platforms driven by a wheel pair.
The system comprises an undercar generator mounted on a rigid frame, located in the undercar space and connected on one side to the frame of the car and/or of the platform by means of the suspension with ball joints at the ends and on the other side to the wheel pair axle by the split rubber bushings arranged in the inner cavity of the split hollow shaft. The surface of said split hollow shaft has concentric grooves for rolling the detachable supports on the rollers, and a drive connecting the wheel pair axle to the generator shaft .
The drive is realized as a two-step transmission, consisting of a gear transmission and a belt-and-pulley transmission interacting with each other. The gear transmission is realized as a drive gear and a driven gear coupled with one another. The belt-and-pulley transmission is realized as a drive pulley and a driven pulley connected by a drive belt. The drive gear is of split-type and is mounted on a divided hollow shaft. The driven gear of the gear transmission is mounted at the end of the intermediate shaft fixed to a rigid frame and provided with a mechanism adapted to discouple from the drive gear. The drive pulley of the belt-and-pulley transmission is mounted at the other end of the intermediate shaft and the driven pulley of the belt-and-pulley transmission is mounted on the
generator shaft. The drive belt of the belt-and-pulley transmission can be made detachable.
The belt-and-pulley transmission in the system can be implemented as a V-belt transmission with a V-shaped drive belt.
The V-shaped drive belt in the V-belt transmission can be made detachable.

DETAILED DESCRIPTION
System proposed herein relates to the systems for autonomous power supply of railroad preferably freight cars and/or
platforms driven by a wheel pair.
The system comprises an undercar generator mounted on a rigid frame, located in the undercar space and connected on one side to the frame of the car and/or of the platform by means of the suspension with ball joints at the ends and on the other side to the wheel pair axle by the split rubber bushings arranged in the inner cavity of the split hollow shaft. The surface of said split hollow shaft has concentric grooves for rolling the detachable supports on the rollers, and a drive connecting the wheel pair axle to the generator shaft .
The drive is realized as a two-step transmission, consisting of a gear transmission and a belt-and-pulley transmission interacting with each other.
The gear transmission is configured as a drive gear and a driven gear coupled with one another.
The belt-and-pulley transmission is realized as a drive pulley and a driven pulley connected by a drive belt.
The drive gear is of split-type and is mounted on a divided hollow shaft. The driven gear of the gear transmission is mounted at the end of the intermediate shaft fixed to a rigid frame and provided with a mechanism adapted to discouple from the drive gear.
The drive pulley of the belt-and-pulley transmission is mounted at the other end of the intermediate shaft and the driven pulley of the belt-and-pulley transmission is mounted on the generator shaft.
The drive belt of the belt-and-pulley transmission can be made detachable.
The belt-and-pulley transmission in the system can be implemented as a V-belt transmission with a V-shaped drive belt.
The belt-and-pulley transmission in the sheaves can comprise several grooves. The number of grooves depends on a power transfer level.
The V-shaped drive belt in the V-belt transmission can be made detachable.
The autonomous power supply system comprises the generator 1 located in the undercar space and the drive, connecting it with the wheel pair of the car and / or the platform.
The drive is realized herein as a two-stage unit and
comprises the first stage and second stage. It may be realized also as three or more stage unit.
The first stage of the two-stage drive is a gear
transmission. It consists of the detachable drive tooth gear 2 coupled with the driven gear 3. The tooth gear 2 is mounted on the split hollow shaft 4.
The driven gear 3 is mounted at the end of the intermediate shaft 5. The driven gear 3 is adapted to discouple from the tooth gear 2 by means of the mechanism 6. The discouple
mechanism 6 may be of any known type, suitable to fulfill this couple/discouple function.
The hollow shaft 4 is fixed on the axle 7 of the wheel pair of the car and/or the platform with the split rubber bushings 8 placed in the inner cavity of the hollow shaft 4. The second stage of the two-stage drive is a belt-and-pulley transmission comprising of the drive pulley 9, driven pulley 10, drive belts 11 and the tensioning device 12. The drive pulley 9 is mounted at the end of the intermediate shaft 5 opposite to the location of the driven gear 3. The driven pulley 10 is mounted on the generator 1 shaft.
The drive belt 11 can be made detachable. The belt-and- pulley transmission can be implemented as a V-belt
transmission with a V-shaped drive belt. The V-shaped drive belt can be made detachable.
In the known devices, if the drive belt of the belt-and- pulley transmission breaks, it is obligatory to roll the car truck out from under the car or the platform and release the wheel pair for installing a new belt over its axle.
The proposed construction of the belt-and-pulley
transmission is assumed to be detachable. It is adapted for fast and convenient drive belts maintenance (e.g. change).
If the belts break, it allows replacing them without rolling the car trucks out, thereby improving and making easier the system maintenance.
The belt-and-pulley transmission, based on the V-shaped belt, has is widely applicable in almost all sectors of the light and heavy industry throughout the world.
The V-belts, for example, according to GOST 1284.2 - 89 and the like, perfectly perform the task in an extremely wide variety of machines and units, conveyor machines, all kinds of special equipment and many other applications, where
mechanical energy from one mobile unit to another is to be transferred. Due to its cross -sectional V-shape, the V-belts have an extensive list of advantages which make them
outstanding in comparison with other types of transmissions (band transmissions and chain transmissions). Thus, for
example, the V- belt GOST 1284.2 - 89 and the like, does, ot require lubrication, thereby allowing achieving an easy
maintenance without surmounting whatever difficulties. They provide a high smoothness of the moving parts and are
extremely quiet in operation. Due to the induced slippage, the V-belts can easily withstand the overload applied thereto, without breaking and deteriorating. Moreover, due to their relative technological simplicity, this type of transmission is easy to manufacture and easy to install.
The generator 1, the belt tensioner 12 of the belt- and-pulley transmission and the intermediate shaft 5 are mounted on the rigid frame 13. The frame 13 is supported on one side at two locations by the hollow shaft 4 via the rolling bearings 14, and, on the other side, by the suspension 15 connected at one end to the rigid frame 13 and at the other end to the frame - to the car 16 and/or the platform via the spherical joints 17.
The split rubber bushings 8 allow the centering of the hollow shaft 4 with respect to the wheel pair axle 7 and the transfer of torque from the wheel set to the hollow shaft 4. At the ends of the shaft 4 there are grooves for rolling on there the roller bearings 14 mounted in the frame 13, allowing the wheel pair to rotate freely relative to the pair of the rigid frame 13 without radial and axial
displacements.
The presence of spherical joints 17 in the
suspension 15 and the free rotation of the rigid frame 13 relative to the hollow shaft 4 allows the gear and belt transmissions to stay in their planes when the car and/or the platform pass curved tracks. The ability to discouple the gear 3 from the drive tooth gear 2 permits not to rotate the drive and the generator during the empty runs of the car and/or the platform.
The proposed device operates as follows.
The indispensable condition of proper operation of this power supply system is the parallelism of the wheel pair 7 axle, the intermediate shaft 5, the shaft of the generator 1 and the coincidence of groove planes of the drive 9 and driven 10 pulleys of the belt-and-pulley transmission.
Before the operation, the gear 3 is coupled with the drive tooth gear 2 by means of the mechanism 6. During the car and/or the platform motion, the wheel pair via the rubber bushings 8 transmits the torque to the generator shaft 1 through the hollow shaft 4, drive tooth gear 2, driven gear 3, intermediate shaft 5, drive pulley 9, belts 11 and the driven pulley 10 mounted on the shaft of the generator 1,
sequentially .
The presence of the rigid frame 13 and its connection with the hollow shaft 4 via the roller supports 14 provides the support of parallelism stability of the generator shaft 1 in relation to the wheel pair axle and the absence of axial displacements. The ability of the frame 13 to rotate around the hollow shaft 4 on the roller bearings 14 and the presence of spherical joints 17 of the suspension 15 allows the frame 13 to move in relation to the car frame or the platform 16 while passing the curved tracks.
In general, the proposed solution enables the autonomous power supply of the cars/platforms from the wheel pair axles of the mainly freight car trucks while passing straight and curved tracks, and makes it possible to switch off the drive during empty runs.
Thus, the advantages of the proposed device, in comparison with the known ones are as follows: - they provide higher repair- and maintainability - the ability to perform the installation and the replacement of the drive belts without rolling out the wheel pair;
- they provide the ability to use the belts of wide range of lengths ;
- they provide a required level of power generator with a prospect to boost it by using two or more stages;
- gear discoupling function allows not to rotate the
generator drive during empty runs, thus increasing the service life time of the drive and the generator bearings.
