Embodiment Construction

[0023] 1 , 2 , 3 relate to a rear axle, the direction of travel of which is indicated by the reference number 1 . There is no representation of the car itself. The suspensions of the right wheel 2 and the left wheel 3 and their wheel supports 4, 5 are of course symmetrical. Wheel frames 4, 5 are fixedly connected or integrated with wheel longitudinal swing arms 6 (right), 7 (left). The longitudinal wheel arms 6 , 7 are here hollow bodies in the form of bent tubes, which are articulated pivotally on the vehicle in joint points formed by the first elastic bushings 8 , 9 . The first elastic bushing allows rotation about the pin 8' in the x-z plane and a slight pivoting of the wheel longitudinal arms 6, 7 in the x-y plane, and rotation in the y-z plane when the wheel camber changes. It is also possible to use a ball and socket joint instead of a bush. Furthermore, transverse control arms 12 , 13 are provided. The right transverse control arm 12 is articulated at an articulatio...

Abstract

An independent wheel suspension for the wheels (2,3) is composed of: longitudinal control arms (6,7), which are connected at one end to the vehicle in an articulated fashion and at the other end to a wheel carrier (4,5) in a secure fashion, transverse control arms (12,13), which are connected to the vehicle and to the wheel carrier (4,5) in an articulated fashion, and further connections between longitudinal control arms (6,7) and the vehicle whose articulation points (22, 27) are offset with respect to the articulation points (14,16) of the transverse control arm (12,13), which causes the toe-in and king pin inclination to be adjusted independently of the spring deflection.; The rest of the connection is in each case a leaf spring (20,25) which is arranged approximately in the transverse direction of the vehicle and one end (21,26) of which is clamped in a secure fashion to the motor vehicle and the other end of which is connected to the longitudinal control arm (6,7) in an articulated fashion at the articulation point (22,27). The leaf springs (20,25) are connected (30) to one another in the central plane of the vehicle.

Description

technical field [0001] The invention relates to an independent suspension for the wheels of the axle of a motor vehicle, which comprises, for each wheel component: a wheel longitudinal swing arm, one end of which is articulated with the motor vehicle or subframe a fixed connection to the wheel frame; a transverse control arm, which is hinged at one end to the vehicle and at the other end to the wheel frame; The articulation points on the wheel trailing arms are offset relative to the articulation points on the transverse control arms. Background technique [0002] Can involve front or rear axles, driven or non-driven. The following directional axes use the symbols commonly used in automobile manufacturing: x-axis=longitudinal axis, y-axis=horizontal axis, z-axis=height axis. The terms x-direction, y-direction and z-direction are used accordingly. [0003] A wheel suspension of this type is known, for example, from patent document GB310391. It consists of the upper transv...
