Embodiment Construction

[0023] With reference to the above-mentioned figures, the reference numeral 4 generally designates an overall schematic view of a saddle-riding motor vehicle according to the invention.

[0024] For the purposes of the present invention, it should be pointed out that the term saddle motor vehicle must be understood in a broad sense without limitation in terms of size, material, motor size and engine type.

[0025] The definition of saddle type means that the motor vehicle is provided with a saddle 6, and the driving user is provided as the rider of the saddle itself, in particular the driving user has leg.

[0026] The saddle motor vehicle 4 comprises a front end frame 8 extending along the longitudinal direction Y-Y and supporting at least one front wheel 12 in a rotatable manner. The front wheels 12 are usually steered wheels; it is also possible to provide a quadricycle with two front steered wheels which may be connected together so as to be rigidly connected or connected...

Abstract

A riding-saddle motor vehicle (4) comprising a front frame (8) which extends along a longitudinal direction (Y-Y) having at least one front wheel (12), a rear frame (14) having a pair of rear wheels (16, 20) mounted on opposite sides of a rear wheel axis (22), a motor unit (24) mounted on board said front frame (8) and adapted to provide a driving torque to said pair of rear wheels (16, 20) and / or said front wheel (12). Said motor unit (24) is connected to said rear wheel axis (22) by means of an articulated transmission joint (32) adapted to allow a relative rotation, around said longitudinal direction (Y-Y), between said front frame (8) and said rear frame (14), and transmit a driving torque to said pair of rear wheels (16, 20).

Description

technical field [0001] The invention relates to a saddle motor vehicle having at least three wheels, including two rear wheels. Background technique [0002] It is known that motor vehicles with two rear wheels are used not only for transporting passengers, but especially for transporting objects, which motor vehicles have a considerable load capacity and stability due to the presence of the rear wheels paired with each other. [0003] Known motor vehicles have a front frame comprising at least one front wheel and a rear frame comprising a pair of rear wheels. [0004] The motor unit is mounted on the rear frame such that the front frame can be tilted with respect to the median plane of the motor vehicle. This kinematic mechanism allows facing curves as in normal two-wheeled motor vehicles and at the same time is able to carry the load on the rear axle at the rear wheels, making this load practically independent of the front end. [0005] However, there are some disadvanta...
