Definitions

  • the present invention relates to a covered small size high mobility three wheel vehicle for light duty transportation.
  • Another drawback of such a vehicle is a poor stability thereof on bends since said vehicle is provided with three conventional wheels.
  • the aim of the present invention is to overcome the above mentioned drawbacks, by providing a covered small size three-wheels vehicles, having high mobility and transportation capability features, which allows to properly protect the driver thereof from the atmospheric agents, without hindering its "agility" in the city traffic.
  • a main object of the present invention is to provide such a three-wheel vehicles allowing to easily load thereon small articles susceptible to be easily arranged in suitably provided spaces.
  • Another object of the present invention is to provide such a three-wheel vehicle which has a very high driving stability and facility, together with very good aesthetic and operating properties.
  • Yet another object of the present invention is to provide such a three-wheel vehicle which has comparatively low making and maintenance costs.
  • a small size high mobility three-wheel vehicle for light duty transportation characterized in that said vehicle comprises a vehicle frame, coupled to a chassis, and supporting a central front wheel and two side rear wheel, a suspension assembly being moreover provided for suspending said rear wheels thereon, said suspension assembly including swinging forks supporting said rear wheels, and being interconnected by an equalizer element causing said forks to swing in an opposite direction for allowing said vehicles to be slanted in a bend.

  • the covered small size high mobility three-wheel vehicle for light duty transportation which has been generally indicated by the reference number 1, comprises a main vehicle frame 2 which, advantageously is made of a steel material. Said vehicle frame is coupled, by resilient supporting elements, to the vehicle chassis 3, which is provided with a protective cap or cover 4 for protecting from atmospheric agents and operating both as a windshield and as a covering element for covering the regions of the seat 5 where the driver will be arranged.
  • a vehicle sub-frame is moreover provided, supporting the vehicle engine and mechanical parts, and being pivoted to the main frame so as to allow the chassis to be fully tilted and so as to facilitate the assembling and disassembling of the vehicle.
  • the vehicle is provided with a front central wheel, indicated by the reference number 10, which is advantageously supported by a cushioned front fork 11 which is coupled to a handlebar 12.

  • a cushioning element 40 is connected, which substantially vertically extends and is articulated to a connecting rod 21 mounted on the vehicle frame.
  • This interconnection is very important since it will allow the vehicle to be bent on a road bending, as if it would be provided with a single wheel, thereby providing an enhanced stability.
  • the rear wheels are provided with a great swinging range capability, in order to provide a great stability even at comparatively high running speeds.
  • the vehicle has been specifically designed so as to fit the movable portion size thereof to the loading requirements, with the possibility of providing receiving spaces for batteries, in an electric ⁇ type of the vehicle.
  • the subject vehicle can be driven in a very easy manner, even by an unskilled driver and, moreover, the vehicle has a high stability bend performance, even at a comparatively high running speed, the driving thereof being particularly amusing.
  • a free wheel vehicle which, owing to its specifically designed rear suspension assembly, is provided with novel features allowing the vehicle to be easily tilted on a road bending.
  • the used materials, as well as the contingent size and shapes can be any, depending on requirements.

Abstract

L'invention concerne un véhicule utilitaire à trois roues, de petite dimension et à haute mobilité, destiné à des transports légers. Ledit véhicule est essentiellement caractérisé en ce qu'il comprend une structure (2) reliée à un châssis (3) et supportant une roue centrale avant (10) et deux roues latérales arrière (15). En outre, un système (20) de suspension des roues arrière (15) comprend des fourches (21) de balancement, entre lesquelles sont placées les roues arrière (15), reliées l'une avec l'autre par un stabilisateur (30) qui provoque le balancement des fourches (21) dans un sens opposé afin de permettre au véhicule de s'incliner dans un virage.
