Abstract:
1. A trailer for a trailer truck, the trailer comprising; a chassis comprising a central chassis element: at least one wheel axle with an independent wheel suspension, which is connected to the chassis, the at least one wheel axle for rotatably supporting a wheel mounted thereon; the independent wheel suspension comprising: a first, lower wheel suspension arm having a first end which is pivotally connected to the chassis, under the central chassis element, about a first pivot axis that extends substantially in a longitudinal direction of the chassis, a second, higher wheel suspension arm having a first end which is pivotally connected to the chassis about a second pivot axis that extends substantially in a transverse direction of the chassis, a steering knuckle, which extends between a second end of the first wheel suspension arm and a second end of the second wheel suspension arm, connecting the first wheel suspension arm and the second wheel suspension arm, the second end of the first wheel suspension arm being spaced from the first end of the first wheel suspension arm by a distance (y), as seen in a top plan view of the independent wheel suspension, wherein the at least one wheel axle is attached to the steering knuckle, wherein the second end of the second wheel suspension arm is spaced from the first end of the second wheel suspension arm by a distance (x), as seen in the top plan view of the independent wheel suspension, wherein the second wheel suspension arm comprises at least two hinges spaced from each other, in line with the second pivot axis, at the first end of the second wheel suspension arm for connecting the second wheel suspension arm to the chassis, wherein the second wheel suspension arm is substantially Y-shaped, wherein a hinge of the at least two hinges is provided at a free end of each of two diverging legs of the Y-shape that form the first end of the second wheel suspension arm, wherein the second wheel suspension arm is connected to the steering knuckle at a free end of a single leg of the Y-shape that forms the second end of the second wheel suspension arm, the single leg of the second wheel suspension arm extending at an oblique angle from the second end of the second wheel suspension arm toward the chassis, as seen in the top plan view of the independent wheel suspension, and wherein at least one of the two diverging legs of the second wheel suspension arm extends substantially at an oblique angle away from the chassis, as seen in the top plan view of the independent wheel suspension.
