Embodiment Construction

[0035] With reference to the above-mentioned figures, a general schematic diagram of the steering group of a motor vehicle 8 is generally indicated at 4 .

[0036] For the purposes of the present invention, it should be clarified that the term "motor vehicle" must be considered broadly to encompass any motor vehicle having at least two wheels, namely front wheels 10 and rear wheels. Therefore, this definition also includes motor vehicles with three wheels, e.g. motor vehicles comprising a single steered wheel on the front axle and two drive wheels on the rear Motor vehicles with drive wheels. Also included in this definition are four-wheeled vehicles having two front steerable wheels which may be tilted and two rear wheels (whether driven or not).

[0037] The present invention focuses on the front axle 12 of the motor vehicle 8; the rear axle is not described or illustrated. For the purposes of this invention, the rear axle can be of any type. In general, both the rear for...

Abstract

A steering group (4) for a motor vehicle (8) comprising a front frame (16) provided with a steering tube (20) rotatably receiving a steering shaft or pin (24) about a steering axis (X ‑X) swivel, the front frame (16) is provided with an upright (32) integrally formed with the steering tube (20), the front frame (16) includes a steering bracket (36) integrally formed in rotation with the steering shaft (24) . Advantageously, the steering group (4) comprises elastic return means (44) elastically influencing the steering shaft (24) to position itself symmetrically with respect to the front frame (16), the elastic return means (44) being inserted in the upright (32) and the steering bracket (36), so as to compress the elastic reset device when the steering shaft (24) rotates relative to the central symmetrical position, wherein the elastic reset device (44) has a regression tendency elastic response.

Description

technical field [0001] The invention relates to a steering group for a motor vehicle, and a related motor vehicle comprising said steering group. Background technique [0002] As is known, the front axle of a motor vehicle comprises a steering group connected to the front steered wheels of the motor vehicle. [0003] During use, especially at low speeds, the steering of a motor vehicle may tend to lock, ie apply a steering angle greater than that set by the user via the handlebar. [0004] The reason for this dynamic behavior of the front axle is essentially related to the fact that the front wheels rotate around the steering axis, which has a certain inclination angle with respect to the vertical to the ground. This angle of inclination, combined with the fact that the steering axis does not pass through the pins of the front wheels but is generally set back relative to the pins in the direction opposite to the direction of travel, gives the front wheels a so-called "trail...
