RU2753938C1 - Steering control apparatus for a motor-wheeled vehicle - Google Patents

Abstract

FIELD: vehicles.

SUBSTANCE: invention relates to a steering control apparatus for a motor-wheeled vehicle. The steering control apparatus comprises a steering shaft, forks of the motor wheels, a steering tube. Each of the forks of the motor wheels includes two shock absorbers with springs, fixed detachably on a crossbar with the steering tube, fixed whereon is a toothed belt transmission pulley. A raised floor is installed below the floor level of the body or frame of the vehicle, wherein the axis of the steering reducer gearbox, whereon the belt transmission steering pulley is fixed, is placed between said floors. A central pulley is located between the body or frame and the raised floor, receiving rotational movement from the belt transmission steering pulley, the movement is then transmitted by means of belts from the central pulley to each toothed pulley located on the steering tube, which in turn rotates the fork with the motor wheel located therein.

EFFECT: increase in the load capacity, increase in the maneuverability are achieved.

Description

The product proposed in the drawings is called "Steering device for a motor-wheeled vehicle", hereinafter referred to as "control". The product is proposed for use in the field of electric transport and is intended for driving on roads with heavy traffic and off-road, due to the increased maneuverability that arises at the time of using this "control", which provides improved cross-country ability.

I am not aware of any analogues of electric vehicles with a similar steering system. Something similar to the proposed "control" forks has been used in the front forks of motorcycles, bicycles, and shock absorbers in front-wheel drive cars.

In this description, to improve the concept of the above, the Dayunov motor-wheel will be used as an example, although if adopted for production, it is possible to use this "control" with motor-wheels "of any electric vehicle manufacturers.

The essential features that distinguish "management" from the closest "relative" - provided that motorcycles or bicycles are mistaken for such, are the following:

- Using all four or more wheels when performing a maneuver, depending on the number of wheels in the used vehicle model

- Design features of the transmission allowing the vehicle to move at any angle to the axis of movement.

- Facilitated parking, due to the design features of the "control", especially in cities with high traffic density.

- Movement over the terrain off-road (forest, park, etc.) since a vehicle with this "control" has the ability to move directly from the point of location in any direction without needing a section of terrain with a radius for turning.

This product consists of:

1. Of four forks (when used on four-wheeled vehicles, when using a different number of wheels - the number of forks must correspond to the number of wheels), each of which consists of: two shock absorbers - 1, with springs - 2 removably attached to the cross member - 3 with a steering tube - 4 on which (by means of splines, keys or other detachable fasteners) a toothed pulley for a belt drive -5 is fixed (figure 1). After that, the steering tube - 4 is passed through the eyelet - 6 with internal bearings - 7 (the eyelet is attached to the frame or body of the vehicle, it can be located both inside the frame and outside on the body of the frame or body), allowing the steering tube to rotate in place - 4 and the wheel-motor located in the fork - 8, 360 degrees without moving in either horizontal or vertical position (figure 2). A similar principle is used in the front fork of a bicycle.

Below the level of the floor of the body (frame) - 9 of the vehicle, a raised floor - 10 is installed, between which are located: axis - 11, removed from the steering gear - 12, for example, similar to VAZ 2101-2107 or another model, the main thing is that the axis - 11 is perpendicular body (frame) floor - 9 and raised floor -10. On this axis of the steering gear, the steering pulley of the belt drive is fixed - 13. Also, in the center of the underground space between the body (frame) and the raised floor, there is a central pulley - 14, which receives the rotational movement of the steering wheel through the belt - 15 from the belt drive pulley -13 on the axle - 11 of the steering gear - 12. Further, from the central pulley - 14 by means of four belts -16 (of the same section, shape and length), the movement enters each pulley - 5, located on the steering tube - 4, which in turn rotates the fork - 1 with in it, the motor is wheel-8. (Figure 3, the diagram shows a belt for only one fork with a pulley). In the future, in the case of using this "control", in order to avoid stretching and slipping off the belts from the pulleys, it will be necessary to add additional belt tensioners to the design.

Thus, when the driver rotates the steering wheel, a simultaneous rotational force is transmitted to each fork with a motor-wheel, turning them by the same degree of motion angle, which allows the vehicle to move in the selected (depending on the steering wheel rotation) direction of travel, for example, diagonally or sideways, from the location of the vehicle.

To reduce efforts when making a maneuver, it is possible to use pulleys of various diameters, or to install a steering amplifier at the discretion of the manufacturer. A feature of this design, due to the use in forks, shock absorbers and springs, is also the increased carrying capacity of a vehicle with motor-wheels.

To avoid breaking the electrical wiring that supplies power to the wheel motor from a power source, when making a maneuver, it is possible to use a hitch consisting of a plastic case - 17, in which there are two round electrically conductive plates - 18 with a hole in which a metal ball of a slightly larger diameter is inserted, than the holes in the plates - 20. (figure 4). The electrically conductive plates are under the influence of springs - 19, pressing the plates to the ball, which allows them to be kept in constant electrical contact by means of wires - 21, attached to the plates.

Thus, when turning the fork with the wheel motor, the wire from one of the spring-loaded plates (inside the hitch body), rotating with the fork, does not lose contact with the ball touching the second plate in the hitch body. However, taking into account the frictional force between the ball and the hitch plates, when turning and in order to avoid the destruction of the plates and the ball, as well as rubbing and breaking of the supply wire, it is necessary to use an electrically conductive lubricant. In addition, for additional electrical protection of circuits, it is necessary to install electrical fuses of a certain rating.

The "control" design is environmentally friendly, has all driving, independent wheels, low weight, increased carrying capacity (compared to other wheel-motor vehicles - there is no gearbox, clutch, cardan shafts, axles, etc.)
