Abstract
Wheel suspension for a pair of driven motor vehicle wheels, comprising a member (1), which consists of two cast aluminum member elements (2, 3) which are joined to each other. The member is intended to be fixed to a vehicle undercarriage. A wheel carrier (15) for each wheel is carried by the member via an upper and a lower link arm (12, 13), a slotted rod (14) and a longitudinal bar (18). A final drive unit (4) is fixed to the member together with a transverse leaf spring (30), which forms the wheel spring system, without the use of any special through-fasteners.

Wheel suspension for a pair of driven motor vehicle wheels, comprising a member intended to be fixed to a vehicle undercarriage, for each wheel an upper and a lower link arm pivotally joined to a wheel carrier, a longitudinal bar pivotally connectable to the vehicle undercarriage and pivotally connected to the wheel carrier, a slotted rod pivotally joined to the member and to the respective wheel carrier, spring means for providing compression and extension acting between the respective wheel carrier and the member, shock absorbers and an anti-roll bar, a differential carried by the member, and a pair of wheel axles driven by the differential, said axles each being joined to an individual wheel hub mounted in the respective wheel carrier, wherein the member comprises an upper and a lower cast aluminum member element (2,3), said elements being screwed securely to each other and fixing the differential (4) between them via elastic damping elements (7,8).
Wheel suspension for a pair of driven motor vehicle wheels, comprising a member designed to be fixed to a vehicle undercarriage, for each wheel an upper and a lower link arm pivotally joined to the member and to a wheel carrier, a longitudinal bar pivotally connectable to the vehicle undercarriage and to the respective wheel carrier, a slotted rod pivotally joined to the member and to the respective wheel carrier, spring means for providing compression and extension between the respective wheel carrier and the member, shock absorbers and an anti-roll bar acting between the respective wheel carrier and the member, a differential carried by the member, and a pair of wheel axles driven by the differential and which are joined to individual wheel hubs mounted in respective wheel carriers, wherein the spring means are formed by a transverse leaf spring (30), which has a central portion (31) securely fixed to the member (1), and end portions acting against a top side (35) of each lower link arm (13).
Wheel suspension for a pair of driven motor vehicle wheels, comprising a member intended to be fixed to a vehicle undercarriage, for each wheel upper and lower link arms pivotally joined to a wheel carrier, a longitudinal bar pivotally connected to the vehicle undercarriage and pivotally connected to the respective wheel carrier, a slotted rod pivotally connected to the member and to the respective wheel carrier, spring means for providing compression and extension between the respective wheel carrier and the member, shock absorbers and an anti-roll bar acting between the respective wheel carrier and the member, a differential carried by the member, and a pair of wheel axles driven by the differential, said wheel axles being joined to individual wheel hubs mounted in respective wheel carriers, wherein the anti-roll bar (24) is U-shaped and curved, and is joined to each longitudinal bar (18) and to the member (1), the connection to the respective longitudinal bar being approximately midway between the two ends of the respective longitudinal bar.
