Abstract

A device for reduction of tractive resistance of a vehicle, predominantly railway one, mounted on its front and directed motionwise. Device is made in the form of a chamfer socket, end part of which is connected with the tube located along transportation means, and front is located opposite its motion, and with transverse dimensions not exceeding the appropriate dimensions of the transportation means.

Description

The invention relates to transport and can be used to reduce the resistance to movement of vehicles, mainly rail vehicles, especially metro ones.

A known device for reducing the movement resistance of a vehicle, mainly a rail vehicle, which is mounted on its front part and directed in the direction of movement. It is made in the form of a rod, on the free end of which a disc is fixed. The rod is spring-loaded in the axial direction relative to the vehicle and is mounted on it with the possibility of rotation in the horizontal plane. (11.

The disadvantages of the known device are that it does not sufficiently reduce the resistance to movement, because it reduces it only due to the toroidal vortex flow in front of the disk, while the frontal resistance remains unchanged.

In addition, this device does not exclude the loss of speed of movement and additional energy of the vehicle for the movement of air masses in front of it, especially by a subway train, which, moving in the subway tunnels, drives this mass in front of it, like a piston in a cylinder. This movement of air is always felt when the train approaches the subway station. When turning the rod in the horizontal plane, transverse forces from air resistance also act on the main part of the vehicle, which leads to additional transverse loads on it and instability of its movement, which worsens the safety of movement. especially at high speed and turns.

The invention is based on the task of making a device for reducing the movement resistance of the vehicle in such a way that it collects, concentrates and directs the air, which is compressed and moves in front of the main part of the vehicle, into a pipe provided along it, for example near the bottom, which significantly reduces the movement resistance by passing air from the space in front of the main part of the vehicle along it through the pipe. In addition, this, in contrast to the consumption of energy in the prototype, allows you to use the bypass of air through the pipe to obtain additional energy. for example, for vehicle lighting.

This goal is achieved by the fact that the device for reducing the resistance to movement of a vehicle, mainly a rail vehicle, which is mounted on its front part and directed in the direction of movement, is made in the form of an intake bell, the rear part of which is connected to a pipe located along the vehicle, and the front part is placed against its movement and with transverse dimensions that do not exceed the corresponding dimensions of the vehicle. So that the horn does not interfere with visibility from the cab of the vehicle, part of its upper face is made transparent, and the lower face is shortened to the length necessary for inspection. To use (utilize) the flow of air, which passes along the vehicle through a pipe connected to the bell, a propeller is placed in it, the shaft of which is connected to the shaft of the generator, which produces additional electricity that can be used to light the vehicle.

This set of new essential features, which consist in the implementation of a device for reducing movement resistance in the form of an intake bell, which collects and directs the flow of air from the space in front of the main part of the vehicle along it along the pipe, and in the placement of a propeller in it, the shaft of which is connected to the generator shaft , which produces additional electricity, in interaction with a known feature, which consists in the presence of a device mounted on the front part and directed in the direction of movement of the vehicle to reduce the resistance of its movement. significantly reduces resistance. increases the stability and safety of the vehicle movement, and also allows using the air resistance of the vehicle movement to obtain additional energy.

Figure 1 shows a side view of a vehicle with the proposed device, Figure 2 shows a front view of it.

The device is mounted on the front part of the vehicle 1 and has a collection socket 2, the back side of which is connected to a pipe 3, which is placed along the vehicle 1, for example near its bottom.

The transverse dimensions of the assembly socket 2 are made no larger than the corresponding dimensions of the vehicle, and so that it does not interfere with visibility from the vehicle cabin, part of its upper face 4 is made transparent, and the lower part is shortened to the length necessary for inspection.

To use (utilize) the air flow in pipe C, a propeller 5 is placed in it, the shaft of which is connected, for example, through a reducer, to a generator 6, which produces additional electricity that can be used. for example, for vehicle lighting.

The device works as follows.

During the movement of the vehicle 1, the horn 2 collects, concentrates and directs the compressed air from the space in front of the vehicle along it along the pipe 3. This reduces the air pressure in front of the vehicle and, accordingly, the resistance to its movement, and the air flow in the pipe C works as an air harness, on which the vehicle 1 moves, which increases the stability and safety of its movement due to this and due to the absence of transverse loads from the air on the vehicle. The same air flow acts on the propeller 5, rotates it, and it, in turn, is a generator b, which produces additional electricity that can be used to light the vehicle. Thus, at the same time as reducing resistance and improving safety, the negative factor of vehicle movement is turned into a positive one, and this is especially appropriate for subway trains.
