Abstract: The invention relates to a shock absorbing assembly including a steering assembly for a vehicle, such as a mobile crane, and consisting of a shock absorbing leg including an outer tube securable to the frame of the vehicle, a wheel carrier telescopically extensible downwards from the outer tube by a piston/cylinder unit, and a steering assembly for the wheel carrier. The steering assembly includes a steering input coupler at the top end of the shock absorbing leg for transmitting steering forces to the wheel carrier through the piston/cylinder unit.

Abstract: An extrusion damper for interposing between two members to absorb energy of motion which may be induced between the two comprises an outer jacket (1) surrounding a body of plastically deformable energy absorbing material (3) such as lead and a shaft (2) which moves through the outer jacket to deform the lead during induced motion. The body of lead may be fixed relative to the outer jacket and the shaft has a portion of reduced diameter (2a) which moves through the lead. Alternatively the body of lead may be fixed to the shaft and the outer jacket has a portion of enlarged diameter (21a) through which the energy absorber passes. The body of energy absorbing material may optionally be subjected to approximately hydrostatic pressure preferably exceeding the shear yield stress of the energy absorbing material.

Abstract: The present invention relates to a hydraulic unit for an automotive vehicle brake system according to the recirculation principle, wherein each brake system in the area of the hydraulic unit includes a prefilling location which opens into the pump suction conduit to take up brake fluid. Thus, filling of the hydraulic unit can be simplified by prefilling of the secondary circuit in the vehicle.
