Abstract
A spring device for a motor vehicle wheel suspension that includes a first leaf spring made of fiber-reinforced plastic and a second leaf spring made of fiber-reinforced plastic. The second leaf spring is shorter than the first leaf spring and together with the first leaf spring forms a V-shaped structure, which, in the region of the joined ends of the V-shape, has a first fastening device for the vehicle-body-side support and at the free ends of the V shape has a second fastening device on the first leaf spring for wheel-side support and a third fastening device on the second leaf spring for vehicle-body-side support.
Claims12
A motor vehicle wheel suspension comprising:
- a spring device provided on each respective wheel side of the motor vehicle, the spring device comprising:
- a first leaf spring made of fiber-reinforced plastic;
- and
- a second leaf spring made of fiber-reinforced plastic, which is shorter than the first leaf spring and together with the first leaf spring forms a V-shaped structure, which, in a region of joined ends, has a first fastening device for a vehicle-body-side support and at a free end of the first leaf spring, a second fastening device is provided for wheel-side support and at a free end of the second leaf spring, a third fastening device is provided for vehicle-body-side support,
- wherein, on each wheel side, the first and second leaf springs each extend in a vehicle transverse direction or extend at an angle of at most +/−15° from the vehicle transverse direction when viewed in a horizontal plane, and
- wherein the spring device provided on each wheel side has a coupling member that extends from the vehicle-body-side connection of the first fastening device in the direction of the vehicle center, such that the coupling member provides an extension of a length of the spring device in the direction of the vehicle center, wherein the coupling member of each wheel side are interconnected to one another at the vehicle center by a joint to reduce the mutual compression of the spring devices.
