Four-point link

A four-point link for an axle suspension of a rigid axle of a vehicle, the four-point link comprising:

• four bearing seats (3) of which two bearing seats (3) are pivotable on the axle and two bearing seats (3) are pivotable on a frame of the vehicle, at least one of the four bearing seats is aligned in a longitudinal direction of the vehicle,
• a twistable link body (1, 2) having lateral side edges and a laterally intermediate region centrally located between the side edges, the link body is substantially inscribed by a trapezoid formed by the four bearing seats (3), and the link body (1, 2) being a fiber-composite arrangement formed of a fiber material in which at least three quarters of a mass of fibers of the fiber material are aligned in the longitudinal direction of the vehicle, the link body having an upper surface and an opposed lower surface that are spaced from one another such that a space between the upper and the lower surfaces in the intermediate region is at least as great as a space between the upper and the lower surfaces at the side edges of the link body,
• the fiber-composite arrangement comprising at least one longitudinal fiber arrangement (10, 11) which is dedicated to at least one bearing seat (3), and the at least one longitudinal fiber arrangement (10, 11) encases at least along half a circumference of the at least one bearing seat (3) and extends along at least part of the link body (1, 2), and
• the link body (1, 2) forms a profile having a first open passage that extends in a lateral direction of the vehicle completely through the four-point link between the upper and the lower surfaces, and a second open passage that extends in the longitudinal direction of the vehicle completely through the four-point link between the lateral side edges and the upper and the lower surfaces.

A four-point link for an axle suspension of a rigid axle of a vehicle, the four-point link comprising:

• four bearing seats (3) of which two bearing seats (3) can be articulated on the axle and two bearing seats (3) can be articulated on a frame of the vehicle;
• a twistable link body (1, 2) which is substantially inscribed by a trapezoid formed by the four bearing seats (3), and the link body (1, 2) being formed of a fiber-composite arrangement;
• the fiber-composite arrangement comprising at least one longitudinal fiber arrangement (10, 11) which is dedicated to at least one bearing seat (3), and the at least one longitudinal fiber arrangement (10, 11) encases at least along half a circumference of the at least one bearing seat (3) and extends along at least part of the link body (1, 2);
• and
• the link body (1, 2) comprises at least one variable-length spacer (8) located between two opposing walls (6, 7) of the link body (1, 2).
