Embodiment Construction

[0032] Referring to the drawings, reference numeral 1 denotes an independent suspension for a vehicle according to the present invention. As already mentioned, the term "independent suspension" is intended to define an assembly configured to allow each wheel of the same axle to move vertically (ie react to bumps on the road) independently of the other.

[0033] Preferably, the suspension 1 is a suspension for directional wheels, more preferably the front wheels of the vehicle.

[0034] The suspension mainly includes: a steering knuckle 2 (with pins), on which the hub 3 of the wheel 4 is rotatably constrained during use; a pair of cross arms, namely an upper cross arm 5 and a lower cross arm 6; And the knuckle bracket assembly 7, which is pivoted to the arm by means of specific (horizontal) articulation points 5a, 6a and is rotatably associated with the knuckle 2 to allow rotation about the steering axis "A".

[0035] The knuckle 2 extends between an outer part 2 a and an inne...

Abstract

An independent suspension for vehicles, in particular for heavy vehicles, comprises a steering knuckle (2) developing between an outer portion (2a), defining the axis of rotation of a wheel hub, and an inner portion (2b), having a receiving seat extending transversely to the outer portion along a steering axis (A) and a knuckle-carrier (7) assembly rotatably coupled to the inner portion of the knuckle (2) to allow a relative rotation around the steering axis (A), and comprising at least a first (7a) and a second supporting portion (7b) defining each a substantially horizontal hinge point (5a,6a) for one end of a respective cross arm (5, 6). The knuckle-carrier assembly (7) comprises a first (16) and a second body (17), separate to each other, in which the first body (16) comprises a steering pin (11) developing along the steering axis (A) and the first supporting portion (7a), and the second body (17) is partially fitted around the steering pin (11) and comprises the second supportingportion (7b).

Description

technical field [0001] The present invention relates to an independent suspension for a vehicle, in particular preferably but not exclusively a suspension for steering wheels of a vehicle of passenger transport type such as a bus, coach, minibus. [0002] Therefore, the present invention is applicable to the field of automobiles, especially to the structure of the steering shaft. Background technique [0003] In the known art, independent suspensions have been invented for a long time, ie they are constructed to allow each wheel of the same axle to move vertically independently of the other (ie to react to bumps in the road). [0004] In the field of heavy vehicles, three independent suspension solutions are known, namely: [0005] Steering knuckle bracket; [0006] ball joint; [0007] "T" connector. [0008] The "classic" solution utilizing a knuckle bracket aims at connecting the upper and lower cross arms to the knuckle (which supports the hub) by means of a knuckle ...
