摘要： A suspension unit of a vehicle, particularly for an electric vehicle, comprises a frame module (16) and two wheel supports (28) each connected to the frame module (16) by an upper oscillating arm (29) and a lower oscillating arm (30), each arm having a first end portion swivelly connected to the respective wheel support (28) by means of a first swivel joint (31, 33) and a second end portion swivelly connected to the vehicle frame (16) by means of at least one second swivel joint (32, 34). The suspension spring means (LS) comprise a single leaf spring (LS), constituting a separate element with respect to the upper and lower oscillating arms (29, 30) of the suspension and arranged transversely with respect to the longitudinal direction of the vehicle, in a symmetrical position with respect to the vertical median plane of the vehicle. The leaf spring (LS) has a central portion connected to the frame module (16) and end portions connected to the upper oscillating arms (29) of the suspension. In a further improved version, the central portion of the leaf spring (LS) is connected to the frame module (16) by a device (57) for adjustment of the position in height of said central portion with respect to the frame module (16).

摘要： An electric vehicle comprises a vehicle frame module (16) carrying an electric motor unit (25) and a suspension (13) including, for each wheel, an upper oscillating arm (29) and a lower oscillating arm (30), connected to a wheel support (28) by means of swivel joints (31, 33) which define a steering axis (11) of the wheel. The suspension further comprises two shock absorber devices (D) arranged in substantially horizontal positions and along directions substantially transversal with respect to the longitudinal direction of the vehicle, below or above the electric motor unit (25), which is carried by the frame module (16) centrally on the vehicle. Each shock absorber cylinder (D) is operatively connected to a respective oscillating arm by means of an oscillating linkage member (41). In one example, the spring means of the suspension are constituted by a leaf spring (LS) arranged transversally above the suspension unit. The brake discs (9) are arranged at remote positions with respect to the wheels, on two output shafts (26) at two opposite sides of the above mentioned electric motor unit (25), which, in one example, comprises two electric motors and two respective gear reducer units from which there project the above mentioned output shafts (26) carrying the brake discs (9); the latter are connected to the wheel hubs (H) by means of two drive shafts (27). The suspension arms define steering axes (11) passing through the wheel centers (C) with no need of extending the wheel supports (28) upwardly above the wheels. In one example, with each shock absorber cylinder (D) there is associated an actuator for suspension active control and with the leaf spring (LS) there is associated an actuator for controlling the height of the vehicle with respect to the ground.
