The drive rail of the xxi century
The invention relates to the unit of electric rail transport. As a traction motor is applied to the stepping motor, accumulating kinetic energy in the drive system introduced reversible hydrostatic transmission and intermediate gear. The controller is equipped with a microprocessor, in conjunction with the specified motor, provide a highly efficient energy recovery during braking of transport and increase the efficiency of operation in General, as when braking transport a large part of the kinetic energy accumulated by the rotor of the stepping motor. This electrohydroblock wheels and hydraulic brakes to be fitted with each leading trolley cars. In comparison with the existing specified the drive consumes significantly less power, increasing the efficiency of rail transport in General. 2 Il. The invention relates to the unit of electric rail transport.Known electric rail transport, containing the traction motor, which is connected through a reversible hydrostatic transmission and intermediate gear with prevodilacka known electric drive is the low efficiency of the motor, torque the flywheel with a high speed, which increases the demands on the transmission.The aim of the invention is to increase the efficiency of the traction motor, transmission and efficiency of the operation as a whole.This goal is achieved by the fact that it as a traction applied to the stepping motor , is designed as a battery kinetic energy supplied from the contact network established on the leading bogie under the bottom of the car with vertical axis of rotation of the rotor-battery, kinetic energy, allowing to recover energy during braking of the transport. Inside the motor is hosted generator low voltage. For optimal operation mode of the actuator used the controller with a microprocessor.In Fig. 1 shows the drive axle truck tram car, bottom view, and Fig.2 is a view of the power unit by A, where 1 is the main transmission; 2 - propeller shafts; 3 - intermediate gear; 4 - motors; 5 - high-pressure hoses; 6 - pump high pressure; 7 - stepper motor.The drive works as follows.When turning on the motor 7 will work given them the ez pump intermediate gear 3, the drive shaft 2 and the main gear 1 rotates the axis of the wheels, while the electric drive allows you to transfer kinetic energy from a constantly rotating motor to the wheels during braking back from the wheels to the motor, and it is additionally charged. Controller with microprocessor provides the optimum drive mode in General. Constantly running generator low voltage provides power lighting and other electrical appliances. The same, independent of other electrohidrodinamica each equipped with a leading bogie wagons.Control of electrical drives is controlled from a Central console driver of transport, in this case, depending on the load, the number of included trucks may vary.In comparison with a known, specified the drive consumes significantly less power, increasing the efficiency of rail transport in General.Sources of information 1.

FIELD: railway transport.
SUBSTANCE: body 1 is installed on frame of bogies 2 connected by springs 3 with wheelsets 4. Spring 6 are connected with body 1 and with beams provided with hubs on studs of which wheels with pneumatic tires are fitted. Projection 14, 5-25 cm high, with gentle slopes 15 are made on rails 13. Car is pulled by truck-tractor onto projections 14 along gentle slopes 15. Wheels 10 are fitted on studs of hubs and then car is rolled off from projections 14 along gentle slopes 15 and is trailed to stores by truck-tractor. Then cargo from car is discharged, and car is pulled back to station and rolled onto projections 14. Wheels 10 are removed from hubs after which car is rolled off from projections 14 onto rails 13 is coupled with locomotive.
EFFECT: improved efficiency.
