A wheel suspension for a motor vehicle including a wheel carrier supporting a wheel. The wheel carrier connected via at least one upper camber link, a lower control arm, and a lateral toe link to the vehicle body or subframe. A stabilizer rod connects to the wheel carrier. The wheel suspension including a damper unit and a spring unit wherein the stabilizer rod and the damper unit connect to the wheel carrier at a common connecting point.

Some embodiments are directed to a suspension assembly of a vehicle having a frame and an engine. The suspension assembly can include a trailing arm having first and second ends and configured to extend from the frame at the first end. The suspension assembly can further include a knuckle connected to the second end of the trailing arm. The suspension assembly can include an arm assembly configured to extend from the frame to support the knuckle and facilitate translational movement of the knuckle relative to the frame in at least one predetermined direction. The suspension assembly can include a damper and a connecting link configured to extend from the frame and connected to the trailing arm. The suspension assembly can include a stabilizer bar connected to the connecting link and extending rearward around the engine.

A vehicle includes a vehicle body, a road wheel, and a suspension corner connecting the road wheel to the vehicle body. The suspension corner includes a suspension arm connected to the road wheel and to the vehicle body, and also includes a suspension force decoupling system disposed on an axis extending between the suspension arm and the vehicle body. The suspension force decoupling system includes an actuator having an actuator mass arranged on the axis that is configured to output an actuator force in opposite directions along the axis in response to an actuator control signal. The system also includes a compliant element connected along the axis to the actuator mass and one of the body and the suspension arm, and providing a predetermined level of mechanical compliance. A controller determines and generates the actuator force in response to a threshold acceleration of the vehicle body.

A control arm for a wheel suspension of a motor vehicle. The control arm including a base body having a spring seat for receiving a helical spring of the wheel suspension. The control arm having a first end region connected to a spring-loaded component of the motor vehicle and a second end region connected to an unsprung component of the motor vehicle. The base body includes a first partial shell composed of steel and a second partial shell composed of a composite material, the shells undetachably fixedly connected to one another at least in one region of the spring seat.

A coil spring for use in a link-motion-type suspension includes a lower end turn portion, an upper end turn portion, and an effective portion of a cylindrical shape between the lower end turn portion and the upper end turn portion. Further, the coil spring includes a bowing control portion including a taper portion formed in at least one end turn portion of the lower end turn portion and the upper end turn portion. The taper portion has a shape whose thickness is reduced from the middle of the end turn portion toward a distal end of a wire along its length, and bowing of the effective portion is suppressed by absorbing a change in the inclination of a spring seat by the taper portion.

A trailing arm device (1) of a drivable torsion beam axle (2) is described. The trailing arm device (1) has a housing (5) in which a drive-train (8) can be arranged and is connected to a trailing arm (4). The housing (5), as fitted into position within a vehicle, has a sidewall (11) formed integrally with a central housing region (9) on a side facing toward a wheel. The sidewall delimits a housing interior space (10) that accommodates, at least partially, the drive-train (8). On the side facing away from the wheel, the housing interior space (10) is delimited by at least one cover element (14) that can be detachably connected to the central housing region (9).

A connecting rod for a multiple connecting rod axle of a motor vehicle, especially a lower wishbone for a multiple connecting rod rear axle, includes a substantially Y-shaped basic framework with a first arm, the free end region of which has a first seat for linking the connecting rod to an auxiliary frame or a vehicle body, with a second arm, the free end region of which has a second seat for linking the connecting rod to the auxiliary frame rod or the vehicle body, and with a third arm, the free end region of which has a third seat for linking the connecting rod to a wheel carrier. The connecting rod is manufactured in one piece with the seats.

The present invention relates to an active suspension system allowing the force acting axis of a spring to be controlled, wherein a control means for the force acting axis of a spring is installed either between an upper seat plate and an upper arm, or between a lower seat plate and a lower arm so as to allow the wheel rate and vehicle height to be controlled by varying the force acting axis of the coil spring, and a manipulation unit capable of controlling the operation of the control means for the force acting axis of a spring is installed inside the vehicle. By varying the force acting axis of the coil spring, the present invention can significantly improve the marketability of the suspension system and reliability of the vehicle by varying the ride quality.

A vehicle includes a vehicle body, a road wheel, and a suspension corner connecting the road wheel to the vehicle body. The suspension corner includes a suspension arm connected to the road wheel and to the vehicle body, and also includes a suspension force decoupling system disposed on an axis extending between the suspension arm and the vehicle body. The suspension force decoupling system includes an actuator having an actuator mass arranged on the axis that is configured to output an actuator force in opposite directions along the axis in response to an actuator control signal. The system also includes a compliant element connected along the axis to the actuator mass and one of the body and the suspension arm, and providing a predetermined level of mechanical compliance. A controller determines and generates the actuator force in response to a threshold acceleration of the vehicle body.

A spring isolator assembly may include an outer shell with a spring track, an inner wall, and an outer wall for receiving a coil of a spring. The spring track may be disposed between the inner wall and the outer wall. The assembly may also include an insert disposed within the outer shell and includes an angled portion disposed between an inner portion and an outer portion. The insert may include a plurality of holes configured to receive the outer shell. The outer shell may include an inner ring disposed adjacent to the inner wall. The outer shell may include at least one spline configured about the inner diameter of the inner ring. The spring isolator may include at least one spline. The outer shell may include an alignment guide.
