ABSTRACT:
A new type of cab suspension and restraining device is provided to retain, in operational position, an automotive truck cab that is pivoted to be swung between an operational position above the truck engine and a maintenance position where the engine is exposed (especially such a cab of the tractor unit of a truck-trailer combination). The device is constructed to provide the cab with a cushioned, air suspension ride by providing a normal air spring between the restraining elements. The device has a housing shell carrying an air spring whose bearing block extends beyond the shell. A portion of this shell fits telescopically into a second housing shell, and restraining means secure the two so that a portion of the first shell is always within the second shell to substantially prevent relative lateral movement of the two but allowing limited relative axial in and out movement thereof to permit operation of the air spring when in operational position.
