Abstract: An axle arrangement for a motor vehicle includes two opposite wheel carriers which are connectable to a bodywork of the motor vehicle via links, and a transverse leaf spring which is connected to the two wheel carriers. The transverse leaf spring is manufactured as one piece from fiber-reinforced plastic, has at least two bands spaced apart from one another and is at least partially integrated in a shear field. The shear field extends between the two wheel carriers and on both sides is connected fixedly to the body or the bodywork of the vehicle and projects beyond the transverse leaf spring, as viewed in the longitudinal direction of the vehicle.

Abstract: A suspension for a vehicle having a chassis rail and a longitudinal axle arranged substantially orthogonal thereto. The vehicle suspension has a primary spring, which may be a leaf spring having a first end for pivotally coupling to the chassis of the vehicle at a first primary pivot coupling, and a distal second end for pivotally coupling to the chassis of the vehicle at a second primary pivot coupling. The primary spring can be a coil spring. A secondary leaf spring has a first end for pivotally coupling to the chassis of the vehicle at a secondary pivot coupling, and a second end for coupling to the axle. The longitudinal configuration of the secondary leaf spring is arranged to be angularly displaced with respect to the longitudinal configuration of the primary leaf spring. The first primary pivot coupling and the secondary pivot coupling are arranged to be substantially coplanar.
Abstract: A suspension for a vehicle having a chassis rail and a longitudinal axle arranged substantially orthogonal thereto. The vehicle suspension has a primary air-responsive spring that couples between the chassis and the axle of the vehicle. The primary spring can be a coil spring that surrounds an air helper spring. A secondary leaf spring has a first end for pivotally coupling to the chassis of the vehicle at a secondary pivot coupling, and a second end for coupling to the axle. The longitudinal configuration of the secondary leaf spring can be arranged to be angularly displaced with respect to a chassis rail of the vehicle.

Abstract: A vehicle drive arrangement for a vehicle of the type having differential power transmission arrangement that converts the rotatory motion of the rotatory power shaft to rotatory motion of first and second drive shafts disposed substantially orthogonal the rotatory power shaft. Primary leaf springs are each coupled at their respective centers to respective drive shafts by pivotal arrangements. The first and second primary springs may include helical springs that are used in place of, or in combination with, the primary leaf springs. Secondary leaf springs may be splayed and therefore need not be arranged parallel to the primary leaf springs. Control over vehicle kinematics is enhanced by configuring the resilience of a fulcrum bumper using resilient, rheological, or active systems. An active system will control vehicle height while stationary to facilitate loading and unloading of the vehicle.
