Abstract
A cab body mounting (100) in a vehicle has a frame-side bracket (102) attached to a chassis frame side rail (18) and a body-side bracket (104) attached to a cab body rail (16). An elastomeric bushing (108) and a fastener (109) associate brackets 102, 104 so as to allow limited motion between them accompanied by bushing deformation. Bracket (102) has an upright wall (110) that is spaced a distance from an end (16E) of rail (16). A sufficiently large relative acceleration of the body on the frame, such as during a frontal impact, will cause an edge portion of bracket (104) to abut wall (110), which arrests further movement of the bracket in the fore-aft direction, and thereby shares the loading that is being imposed on the mounting due to the acceleration force. This occurs before the stress in the shank of fastener (109) reaches the characteristic maximum allowable shearing stress for the fastener material.
