<p>In a motor vehicle steering assembly, for protecting shock sensitive, precision- made and expensive components such as the steering gearbox against impact damage originating at the vehicle's steered wheels, the invention provides at least one force transmission element or buffer member in the steering assembly, between the steering gearbox and steering arms of the steering linkage and which is arranged in use to yield axially when subjected to an axially directed shock- like force exceeding a predetermined maximum service force. In Figure 1 a tie rod coupled by a ball joint 4 to a track rod or a toothed rack includes two parts 1,3 connected by a prestressed resilient body made of rubber or plastics material. In an alternative construction the steering linkage includes a ball joint having a ball socket axially supported in a joint housing by a plastically deformable member. <IMAGE></p> |
