Arrangement for mounting a cab structure to a vehicle frame

摘要

Cab and rollover structures are useful for protecting an operator while operating a vehicle. When an integral cab rollover structure is used it is necessary to provide a mount which will isolate the structure from the frame to reduce vibration and noise and also to provide a solid connection to transfer loads during rollover. The subject mounting arrangement will provide a mounting structure which will isolate the cab rollover structure from the frame in a normal first operating condition to reduce noise and vibration within the cab. In a second condition of operation the isolating structure will deform allowing the mounting structure to contact the frame and withstand forces on the cab rollover structure. This arrangement of components provides an isolated mount which will not be overstressed during a vehicle rollover.
