Abstract

A useful model is a device designed to transform a scooter into a motor vehicle for sports, entertainment and other purposes and to increase its comfort, which is a spatial structure that is easily mounted on a scooter, including a device for transmitting torque from one or two engines to the scooter wheel by means of a friction transmission in the form of a roller in contact with the peripheral surface of the scooter wheel, mount for engines of any kind (including ICE, electric motor, m flywheel, air, etc.) with proper matching, a saddle for the driver and fastening to the scooter. The basis of this design is the frame, which is the fork of the beam scheme, bearing the friction drive roller, rotating in bearings mounted in the holders on the fork beams, resting directly on the axle of the scooter wheel; on the opposite side, this fork has as its basis a seatpost tube, on the lower end of which there is a support for attaching to the scooter frame (platform), a saddle pin is inserted from its upper end. This industrial design differs from known similar devices by the combination of the following features: 1. It does not require any changes in either the presentation of the scooter carrier, or its design in particular, neither during installation nor during its operation; dismantling the PM directly returns the carrier scooter to its original presentation. 2. Mounting the PM on the carrier scooter does not require any third-party (additional) devices, since fastening to the scooter is carried out by supporting the PM fork on the scooter wheel axle with the regular wheel nuts of the scooter clamped to the wheel fork and clamping the front support on the scooter frame (platform). In this case, the friction drive roller comes into contact with the peripheral surface of the scooter wheel, ensuring its direct functioning. 3. The preload and adjustment of the clamp of the friction roller to the scooter wheel is carried out by the weight of the driver, the fixation of the selected position is ensured by the provided constructive take-off in the slots on the forks of the fork resting on the wheel axle. 4. The bearings of the friction roller mounted on the beams of the PM fork are suitable for fastening from any outside of the engine of any kind, including on each clip at a time; and, if desired, even of various kinds (ICE and flywheel, etc.). 5. One of the important distinguishing features of the PM is the adjustable driver seat, the seatpost of which is included in the structural power scheme of the PM.6 frame. The design and decoration of the PM follows, first of all, from the technical feasibility and general functionality of this model, designed to work within the framework of the concept of the most light, cheap and simple motor vehicle. The most pronounced example of this is the combination of mass-dimensional indicators and structural and artistic solutions that complement each other in this design. The absence of excess material leads to a design lacy, the arch of the fork beams successfully perceives the load, minimized due to the fact that in practice the driver’s weight is directly transferred to the wheel through the roller, providing the necessary compression of the friction drive, which makes the constructive presence of the saddle not only convenient from an ergonomic point of view but also functional with technical, etc. 7. The use of the claimed PM model makes the transformation of the scooter into a motor vehicle the most affordable since it ensures the fastest possible installation by the hands of the wearer on any appropriate scooter, the most convenient since the design is made as light as possible and has a saddle, the most liquid in view of absolute safety presentation of both PM and scooter during dismantling. 8. The PM, within the framework of the claimed sample, can be either a unit from a size range for mounting on scooters with different sizes and types of wheels, or be universal, with the possibility of advanced adjustment of the distance from the axis of the scooter wheel to the friction roller.

Description

II. APPLICATION AREA

Land vehicles, scooters, scooter motorization with an increase in its comfort.

III. BACKGROUND

To date, all known technical solutions for the transformation of a scooter into a motor vehicle, for the most part, are an integral part of the scooter design as a whole. Samples of structures that can be mounted on a USUAL MOTOR-FREE Scooter, while maintaining a mutually salable appearance, are a variety of similar structures for bicycles. In these samples, to transfer torque from the engine to the wheel, chain or belt drives are used that require one or another intervention in the original design in view of the need to adapt the wheel to be able to work with the above types of gears. Known designs with a friction roller interacting with the periphery of the wheel, however, in these designs the issue of a certain guarantee of preserving the pre-press roller to ensure the functioning of the transmission during actual operation is not resolved. One of the closest analogues of the claimed product can be considered a "motor drive" RU 19716 U1 (see appendix). This design, hereinafter referred to as ANALOGUE, embodies the idea of motorizing a bicycle by supplying it with a light ICE with a belt drive to the wheel. When installing ANALOGUE, additional elements and fasteners are required, as well as finalization of the drive wheel. With regard to the scooter, ANALOGUE and all similar designs exacerbate their drawbacks, due to the small size of the scooter wheels. In addition, the nature of the scooter, where the driver is standing, and the distance between the axles of the wheels is small, does not contribute to safety when scooter is motorized, when the speed increases significantly with the center of gravity high. Based on the foregoing, the author proposes to express the idea of transforming a conventional scooter into a motor vehicle by implementing the PULSIVE MODULE (PM) design for scooters (Figs. 1-3), which is a spatial frame with a saddle for a driver that is easily mounted on a scooter and designed to carry any suitable engine supporting device for direct transmission of torque from the engine to the wheel, and not requiring additional elements and fasteners during installation and operation.

IV. DISCLOSURE OF THE ESSENCE OF A USEFUL MODEL

A PERSPECTIVE MODULE for scooters (PM) (Fig. 1) is a rigid independent spatial frame in the form of a fork 1 with a seatpost 2 and a driver seat pin 3, attached to the front of the scooter during installation to the frame of the scooter with a universal clamp 4, the bearing roller of the friction gear 6, rotating in bearings, cages 5 of which are fixed on the beams of the fork 1 of the frame, resting on the scooter when mounting the PM directly on the wheel axis (Fig. 3) and, along with the flanges 8 of the roller 6, have a correspondence 7 for mounting forcefully st installation. A power plant that meets this concept in terms of power and weight and dimensions, which is an engine of any kind with a gear change device or without it, is mounted on the flange 7 of the bearing race 5, the output shaft of the engine (power plant) is connected to the friction roller by any type of coupling (blind, compensating, clutch of any type, etc.) or directly (Fig. 2), when mounting the PM on the scooter, the friction drive roller 6 comes into contact with the peripheral surface of the wheels and a scooter, transmitting torque from the power plant to the wheel (Fig. 3). The fastening of the PM fork to the scooter wheel axis has a constructive geometric take-off 9 for the possibility of installing the PM on scooters with different outer diameters of the wheels and for adjusting the friction gear pressure. The weight of the driver is perceived by the seat tube 2 and, partly, through it by the friction gear 6, which is used to adjust the pre-press of the gear and compensate for the weakening of the pressure during operation of the PM.

DIFFERENCES AND ADVANTAGES

A comparative analysis of PM with analogues reveals the following differences and advantages of PM:

PM can carry any engine corresponding to the concept:

ICE, electric, pneumatic, flywheel, etc., and potentially, on both cages at the same time - two engines, even different kinds (ICE and flywheel, etc.), when installing one engine, the flange of the unused cage is closed by a cover (Fig. . 2). The PM does not use belts, chains and other intermediary categories for transmitting torque, which require frequent replacement, lubrication, adjustment and interference with the original design of the carrier. Torque transmission is carried out by a friction roller. The frame design of the PROPULSION MODULE contains a mount for the driver’s saddle (Fig. 2), which, in addition to increasing comfort and safety, due to the lowering of the Center of Gravity, also solves the issue of the preload of the friction drive roller to the scooter wheel, carried out by the driver’s weight. During operation, this gives undeniable advantages, since the well-known drawback of friction gears is slippage when the coupling coefficient suddenly drops (moisture, temperature, loosening, etc.), this is compensated by the possibility of using the driver's weight. The labor costs when installing a PM on a scooter are unprecedentedly low and have no analogues, because they come down only to loosening the wheel nuts of the rear wheel of the scooter, installing the PM on the scooter, clamping the wheel nuts and nuts of the front support and replacing the right handlebar grips with the gas handle included in the PM kit. The nature of the PM fastening allows the friction roller to be brought out of contact with the wheel using the geometric adjustment run of the fork supports. This makes the scooter with PM indistinguishable in ease of free running from a conventional scooter due to the lack of resistance of the drive. PM can be operated without an engine at all. The friction roller is either removed or removed from contact with the wheel, as mentioned above. Scooter converted to a runbike. The geometrical dimensions and weight of the PM, subject to the strength required by the operating conditions, are minimized. The weight of the scooter with PM is minimal among analogues. In view of the minimum material and labor intensity of the PM, its purpose for assembling conventional scooters of common models, the total cost of the resulting motor vehicle is unprecedentedly low.

V. IMPLEMENTATION

PM is prepared for serial production (Fig. 4a-c) in the form of models of two sizes for scooters with pneumatic wheels and one for scooters with all-rubber wheels. Within each frame, the necessary adjustment is provided for the model of a particular wheel. When using the PM for the motorization of the scooter, a very small weight of the vehicle is ensured, lower than the average average bicycle, the cost of the scooter with the PM is lower than the cost of any analogue. PM is made of accessible materials by the simplest operations of cutting and bending sheet steel, turning on a steel circle and welding. Photos of the implemented PM are attached (Fig. 5).
