The invention relates to a device for attaching a balancing weight (2) to a mounting surface (17) on an inner side (3) of a rim dish of a wheel rim (4) and provides for a mounting head (1) to be dimensioned in such a way that it fits into the rim dish. The mounting head (1) includes a support element (5), which is radially displaceable relative to the wheel rim (4) and on which a feeler element (6) is axially movably arranged, the feeler element (6) having a convex contact surface (14) and a receptacle (12) for at least one balancing weight (2), said receptacle being oriented towards the inner side (3). The mounting head (1) is configured in such a way that the contact surface (14) may be brought into contact with a boundary surface (18) of the inner side (3), and may be displaced along said boundary surface until the balancing weight (2) comes radially into contact with the mounting surface (17).

A vibration damper is provided with two rotating members, i.e. an oscillating inertial flywheel and a member to be damped driven by a torque following a torque path between a driving member and a driven member, wherein the inertial flywheel is connected kinematically to the torque path between the driving member and the driven member solely by way of the member to be damped. Connecting modules between the two rotating members permit a relative angular displacement θ between the two rotating members on the two sides of a reference relative angular position. Each connecting module is provided with a roller associated with a first of the two rotating members and a cam track connected resiliently by a resilient element to a second of the two rotating members.

Methods, systems, and devices are described for mounting an antenna assembly to a vehicle, whereby rotational degrees of freedom between the antenna assembly and the vehicle are constrained. For example, an antenna mount may employ an intermediate structure between the antenna assembly and the vehicle. In various examples, the intermediate structure may be coupled with one of the vehicle or the antenna assembly by a linear coupling, and the intermediate structure may be coupled with the other of the vehicle or the antenna assembly by a planar coupling. The antenna assembly may be coupled with the vehicle by a compliant coupling that provides a centering force between the antenna assembly and the vehicle. According to various examples, rotational movement between the antenna assembly and the vehicle may be suppressed, and vibration from the vehicle to the antenna assembly may be attenuated.
