Abstract

This invention relates to railway transport, in particular, to a traction drive locomotive. The purpose of the invention is to reduce the size of the width. The torque from the drive shaft of the axial gearbox is transmitted through the drive gear 9 either to the driven gear 10 of the first stage, then to the fixed gear 18 of the second step rigidly connected to it, to the crown 14 and the wheel set, or to the intermediate gear 13, the driven gear of the second stage and wheelset. In the first direction of the power flow, the gear ratio is approximately twice as large as in the second direction of the power flow. The required gear ratio is set using the control mechanism on command from the control panel of the locomotive. When this gear 9 can be installed in one of three fixed positions corresponding to the maximum, minimum gear ratio or the disabled position - there is no engagement. 3 il.

The BTS includes a body 1 and a sniper with a bottom 2. The body 1 on one side rests on the axles 3 and A of rolling on the axis 5 of the wheelset, and on the other, using reaction 6 (FIG. 1) on the frame of the tray. In addition, the gearbox contains a balanced articulated coupling 7, connecting the shaft of an electric motor; 1 engine with a hollow gear 8 of the gearbox and providing torque measurement at their relative displacements. A gear 9 is installed on the drive shaft of the axial gearbox with axial displacement along with the driven gear 10 of the first stage at its extreme position (Fig. 2) libg with the bearing 11 installed on the psi 12 intermediate gear 13 located in constant chapel with a crown of the 14th century — DOMO11 gears of the second dullness at its extreme ninth position 1, FIG. 3).

The intermediate shaft 1 3, mounted in the housing on bearings 16 and 17 of rolling, pressed the first stage gear 10 and the second stage gear 18, the latter of which is also like the intermediate gear 13 in constant engagement with the rim 1. The bottom is the dynamics drive the crown 14 is connected to the pressed-on (on.-5 wheelset with the hub 19 by means of elastic elements 20.

there is a jagged jungle 23, let's combine -; ; with a Pynemati Iskogo rod 1 cylinder; (and having a constant gearing with a spiked ear 24, which is mounted on the sleeve, it is possible to rotate the roller 26. The sleeve 23 is equipped with a retone1. | m section 27, on which the clip 28 is screwed.

The gearbox works as follows.

The BpauiaKnmiii moment from the shaft of the electric motor 2 is assisted by equilibration of the drive shaft of the clutch 7 and is transmitted to the drive shaft 8 and from it by the drive gear 9 or the driven gear 10 of the first stage, then to the second gear rigidly connected with it 18 on the crown 14, the elastic elements 20, the hub 19 and on the wheelset, or on the intermediate gear 13, the driven gear of the second stage and on the wheel pair. In the first direction of the power flow, the ratio of the axial gearbox is approximately two times larger than the ratio in the second direction of the force I o flow. The required gear ratio is set at the time of the pneumatic system by a command from the locomotive control panel. In this case, the gear rail 23, which is connected with the pneumatic cylinder of the cylinder 1B, can be installed in one of three fixed positions corresponding to the maximum or minimum gear ratio, or the position at which the motor is disconnected from the wheelset. As a result of linear movement of the rail 23, the gear wheel 24 and the sleeve 25 associated with it receive a rotational movement, as a result of which the clamp 28, moving along the threads of the new section 27, moves the gear 9 to a predetermined position. The appropriate signaling devices inform the driver of the operation of the gearshift ratio of the axial 50 gearbox driver.
