Problems solved by technology

[0003] In particular, a three-wheeled vehicle with two single-wheel steering mechanisms and a three-wheeled vehicle with a front two-wheel steering mechanism have been proposed, which have different configurations, however, a compact vehicle cannot be achieved. Production, safe to ride, and easy to maneuver even with the lack of foot support
[0004] In practice, the general problem associated with the aforementioned three-wheeled vehicles can be considered to be the lack of stability of a car despite the handling agility of a motorcycle

Embodiment Construction

[0018] Referring to the accompanying drawings, there is shown a three-wheeled vehicle generally designated 11 with a front two-wheel steering mechanism according to the present invention.

[0019] The vehicle 11 mainly includes a fixed-axle rear wheel 12 , a vehicle frame 13 , and a pair of steered front wheels 14 , 15 . Also, a handlebar 16 is generally provided, through which the steering front wheels 14, 15 can be operated. With this first general scheme, it is evident that the motor propulsion group and the rear suspension are known from any series of vehicles, as is the front suspension, which is described in detail later; even in the novel and original scheme of the present invention, From wheels to steering tubes, complete equipment packages from any series of vehicles are also available.

[0020] The handlebar 16 shown is connected to the frame 13 via a cylindrical hinge 17 which corresponds to the steering axis. A lever 18 is integral with the handlebar 16 and exten...

Abstract

A three-wheel rolling vehicle with front two-wheel steering comprising a frame (13), a handlebar (16), a rear wheel (12) rotating with respect to the frame (13) and a steering group which operates two front wheels (14, 15), in which two horizontal crossbars (21, 22) are foreseen, connected through hinges (40-43) of the side tubes (36, 37) and through additional hinges (23, 24) to the frame (13), the tubes (36, 37) rotatably supporting steering tubes (31, 32).

Description

technical field [0001] The invention relates to a three-wheeled vehicle with a front two-wheel steering mechanism. Background technique [0002] In the field of vehicles, especially those with three wheels, important embodiment changes have been proposed over time. [0003] In particular, a three-wheeled vehicle with two single-wheel steering mechanisms and a three-wheeled vehicle with a front two-wheel steering mechanism have been proposed, which have different configurations, however, a compact vehicle cannot be achieved. Production, safe to ride, and easy to maneuver even with the lack of foot support. [0004] In practice, the general problem associated with the aforementioned three-wheeled vehicles can be considered to be the lack of stability of a car despite the maneuverability of a motorcycle. In short, the aim is to obtain a three-wheeled vehicle that can be steered like a two-wheeled vehicle (with the driver leaning) while maintaining the stability normally given...
