Embodiment Construction

[0052] Referring to the preceding figures, the reference numeral 4 generally designates a schematic overall view of a motor vehicle according to the invention.

[0053] For the purposes of the present invention, it should be noted that the term motor vehicle should be taken broadly to include any motorcycle having at least three wheels (ie two aligned wheels and at least one rear wheel as better described below). Such a definition therefore also includes so-called quadricycles with two wheels on the front bogie and two wheels on the rear axle.

[0054] The motor vehicle 4 comprises a frame 6 extending from a front bogie 8 supporting at least two front wheels 10 , 10 ′, 10 ″ to a rear axle supporting one or more rear wheels 12 .

[0055] A distinction can be made between left front wheel 10' and right front wheel 10", wherein the definition of left and right 10', 10" is purely formal and relative to the driver of the vehicle. Said wheels are arranged to the left and to the rig...

Abstract

A motor vehicle (4) comprises a forecarriage frame (16), a pair of front wheels (10', 10'') kinematically connected to the forecarriage frame (16) by means of an articulated quadrilateral (20), a steering bar which is mechanically associated with handlebars and wheel support elements of each wheel (10', 10'') by means of first and second roll hinges and first and second steering hinges, wherein when the wheels (10', 10'') are straight and parallel to the forward direction, the first and second steering hinges are arranged offset from cross members (24', 24'') of the articulated quadrilateral (20) in the longitudinal direction such that, with respect to a projection plane parallel to the ground, and the straight lines joining the steering axes (S' -S', S'' -S'') of the wheels (10', 10'') with the first and second steering hinges, intersect at a support point of the rear wheel on the ground.

Description

[0001] This application is a divisional application of a Chinese patent application with application number 201680076382.3 and titled "Motor Vehicle" (based on an international patent application with an international filing date of December 27, 2016 and an international application number of PCT / IB2016 / 058018). technical field [0002] The invention relates to a front bogie of a tilting motor vehicle and the motor vehicle thereof. Background technique [0003] As is known, three-wheeled motor vehicles in the prior art have rear drive wheels and two steering and tilting, ie rolling or inclining, wheels at the front. [0004] Thus, the rear wheels are intended to provide torque and thus allow traction, while the paired front wheels are intended to provide directionality to the vehicle. [0005] Using two front wheels instead of two rear avoids adding a differential for torque transfer. This enables cost and weight reductions on the rear axle. [0006] The paired wheels at t...
