TOY RAILROAD CAR DRIVE GEAR REDUCER Russian patent published in 2021 - IPC A63H19/10 A63H19/16 

FIELD: toys.

SUBSTANCE: invention relates to gearboxes of toy railroad carts. The proposed gearbox contains gears installed in the housing, kinematically connected to the driving axles 2 of the bogie wheels electrically isolated from each other. Driving axle shafts 2 with driving wheels 3, 15 at the ends are installed in bearings 4 of the gearbox. Each driving wheel pair is located so that it can move up and down in the vertical plane and left and right in the horizontal plane. In the gearbox housing, elastic electrically conductive plates 8 of the current collection are installed, electrically connecting the driving axle shafts 2 of the corresponding sides of the front and rear wheel pairs, the elastic plates have contact leads for connecting the control board to them and side leads for contact with the wheels of the driven middle axle 9. Plates 8 abut against the upper surface of the current-carrying bearings 4 of the driving axle shafts 2. Between the driving wheels along the length of the gearbox, a steel driven axle 9 is installed with a driven bogie wheel 3 pressed at one end of it and fixed at its other end, by means of an electrically insulating sleeve 11, with another driven bogie wheel 10. The driven axis is installed with a gap in a vertical groove in the cylindrical protrusion 12 of the gearbox housing with the possibility of its free movement in the vertical plane up and down and left and right in the horizontal plane. On the cylindrical protrusion 12, the parasitic gear 13 of the reducer is fixed, which is in kinematic connection with the driving gears 1, which are fixed at the ends of the driving axle shafts 2 and does not have a kinematic connection with the middle driven axis 9.

EFFECT: increasing the reliability and efficiency of the gearbox in conjunction with the work of the bogie, which are combined in one unit of the locomotive drive.
