Embodiment Construction

[0043] With reference to the preceding figures, reference numeral 4 generally designates a motor vehicle according to the invention.

[0044]For the purposes of the present invention, it should be noted that the term motor vehicle should be taken broadly to include any vehicle having at least three wheels (i.e., two aligned wheels and at least one rear wheel as better described below). motorcycle. This definition therefore also includes so-called quadricycles, which have two wheels on the front wheel carrier and two wheels on the rear.

[0045] The motor vehicle 4 includes a frame 6 extending from a front wheel carrier 8 supporting at least two front wheels 10 to a rear portion 12 supporting one or more rear wheels 14 . A distinction can be made between the left front wheel 10' and the right front wheel 10", wherein the definition of left 10' and right 10" is merely formal and relative to the understanding of the driver of the vehicle. The wheels are arranged to the left and...

Abstract

A forecarriage of a rolling motor vehicle (4), comprising a forecarriage frame (16), at least one pair of front wheels, each wheel being connected to a first kinematic mechanism (20) by means of a respective axle journal (60), a roll block system (100) comprising a second kinematic mechanism (110) which is susceptible to take on a free configuration in which it is configured to passively follow the movements of said two front wheels with respect to each other and with respect to the forecarriage frame (16) and a blocked configuration in which it is configured to block the angle formed by a lying plane of at least one front wheel with respect to the ground, said lying plane being orthogonal to the axis of rotation (R'-R', R"-R") of said front wheel.

Description

technical field [0001] The invention relates to a front wheel carrier of a rolling motor vehicle with a roll arrest. [0002] In particular, the motor vehicle according to the invention may be a motor vehicle equipped with two steering and rolling wheels at the front and with fixed axle drive wheels at the rear. Background technique [0003] In the field of motor vehicles, more and more "hybrid" vehicles are offered, which combine the characteristics of a motorcycle with the stability of a four-wheeled vehicle in terms of maneuverability. [0004] Such a model is represented, for example, by a three-wheeled motor vehicle equipped with two front steerable wheels, and by a four-wheeled motor vehicle called a QUAD. [0005] More specifically, the aforementioned three-wheeled motor vehicles are provided with two steering and rolling wheels (ie, tilt or skew) at the front and fixed axle drive wheels at the rear. The rear wheels are intended to provide torque and thus allow trac...
