Abstract
A cab suspension and repositioning system (110) for a truck includes a control arm assembly (130) having two control arms (134, 136) with distal ends pivotably attached to a truck chassis (112) and proximal ends pivotably attached to a cab (102), and one or more follower control arms (144, 146) having a distal end pivotably attached to the chassis (112) and a proximal end pivotably attached to the cab (102). Cab suspension assemblies (114, 170) releasably lock the cab (102) to the chassis (112) during operation. The control arm assembly (130) further provides motion control to the cab (102). Hydraulic cylinders (140) engage the control arm assembly (130) and are operable to move the cab (102) between an operating position adjacent the chassis and an access position away from the chassis (112) substantially without rotating the cab (102). A control system (200) powers the cylinders (140) and controls the transition between the operating and access positions.
