SU11227A1 - Adaptation to the car for driving on rails - Google Patents

Description

The proposed adaptation to a car for driving on rails is related to a car equipped with additional wheels with flanges that are installed in height, and that the axles of the additional wheels are fixed on pivotally connected double-arm levers, whose short arms can be moved and moved apart from the car engine by means of a suitably arranged drive .

In the schematic drawing of FIG. 1 shows a side view of a car equipped with the proposed device; ig. top view; FIG. 3-brake device for extra wheels.

In addition to conventional wheels, the car is equipped with eight railway wheels, themselves 11 with flanges, sitting in pairs on four parallel axes, of which the two front axles are solid, and the two rear 27 are cut (Fig. 2) and connected by a sleeve 34 ,. but without the use of the differential in them, since these semi-axes work through the usual automobile differential 33.

The mechanism for raising and lowering railway wheels consists of a box 26 (Fig. 2) through which the transmission shaft 31 passes from the engine to the differential and in which the clutch mechanism and transmission mechanism of a particular system, such as an epicyclic, is placed, which transmits rotation to the transverse roller 30 in one direction or another, as desired, depending on the depth of pressure of the pedal; Screws 15 (Fig. 1) on this roller transmit the rotation to the worm wheels 16 on both longitudinal rollers 17 having right 24 and left 25 cutting for nuts 23 fastened with short shoulders of two shoulders, hinge-connected, arms 12, at the ends of which axles of additional wheels fortified 11.

The transfer of work to the moving wheels occurs in the case of driving on ordinary automobile wheels, the usual way for a car, for example, in chain transmission, through chains 19, and when driving on railway wheels - using other chains 20 and auxiliary 21a and 22. Switching on some chains with pre-switching off of others, it is produced by moving the lever 4, which using a double set of levers moves the clutches on the sides of the differential 33 (Fig. 2).

To put the car on a ride on rails using rail

wheels 11 with flanges levers 12 (fig. 1), moving together like when closing scissors, using screws 24 and 25 (fig. 2) with right and left threads and using pair nuts 23, which, in order to avoid bending the screw, some slip in the fingers 47 (fig. 3), raise the usual wheels of the car from the rails. When these screws, located in bearings 22 (Figs. 1 and 2), are rotated using a special mechanism from the engine 7: you drive the car in the opposite direction with wheels, you first of all allow the car wheels to stand on the ground, or on the crossing boards, and then they are separated from the ground and in a high position do not interfere with driving a car outside the tracks on its normal wheels. FIG. Figure 1 shows the average position of the railway wheels, when they were just starting up and the automobile wheels touched the ground (or rails).

Special brakes may be attached to the railway wheels 11 (FIG. 3),

in which the brake shoe 48 is pressed against the wheel AND for braking through a system of levers and pull 49, 39, 38, 37, 36, 35, 41, 43-46,

The subject of the patent.

Adaptation to the car for driving on rails using the equipment | extra wheel height: with flanges, characterized by the fact that the axles of the additional wheels 11 are fixed at the ends of the pivotally connected two arms of the levers 12, whose short shoulders can be moved and moved apart from the car engine by; a drive consisting of gear 26, sweat of the pepper roller 30, worm gears 15, 16 and two longitudinal shafts 17 with right and left cutting for nuts 23 ,. c) fixed with levers 12, than the transfer of rotation to the rear drive wheels 11 is made additional; chains 20, 21a and 22a (Figures 1-3).
