Summary: | 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.
Un sistema de reposicionamiento y suspensión de cabina (110) para un camión incluye un conjunto de brazo de control (130) que tiene dos brazos de control (134, 136) con extremos distales fijados de manera pivotable al chasis de un camión (112) y extremos proximales fijados de manera pivotable a una cabina (102), y uno o más brazos de control seguidores (144, 146) que tienen un extremo distal fijado de manera pivotable al chasis (112) y un extremo proximal fijado de manera pivotable a la cabina (102). Los conjuntos de suspensión de cabina (114, 170) bloquean de manera liberable la cabina (102) al chasis (112) durante el funcionamiento. El conjunto de brazo de control (130) proporciona, además, control de movimiento a la cabina (102). Los cilindros hidráulicos (140) acoplan el conjunto del brazo de control (130) y son operables para mover la cabina (102) entre una posición de funcionamiento adyacente al chasis y una posición de acceso lejos del chasis (112) sustancialmente sin girar la cabina (102). Un sistema de control (200) acciona los cilindros (140) y controla la transición entre las posiciones de funcionamiento y de acceso. |
