Abstract
The present disclosure relates to a tilt cab truck having unique cab suspension means and cab tilting means. The suspension includes a pair of front and a pair of rear suspension arms that interconnect the cab and the frame. Front air springs are interposed between the front arms and the frame. The rear arms are connected to the frame by releaseable latch mechanisms and rear air springs are interposed between the latch mechanisms and the cab. Power cylinders for tilting the cab are arranged parallel to the front arms and are connected to the frame and the cab.
Claims23
A tilt cab truck comprising a truck chassis frame, a truck cab and suspension means interconnecting said frame and said cab,
- said suspension means being constructed to accommodate jounce and rebound movement of said cab relative to said frame,
- said suspension means including a plurality of rigid suspension arms and pivot means pivotally connecting said arms to said frame and to said cab,
- pivot means interposed between said cab and said frame providing a transverse tilt axis about which said cab may be angularly displaced relative to said frame,
- means operatively interposed between said cab and said frame constructed to exert a force tending to angularly displace said cab about said transverse tilt axis,
- spring means operatively interposed between said cab and said frame constructed to resiliently support said cab on said frame.
A tilt cab truck comprising a truck chassis frame, a truck cab and suspension means interconnecting said frame and said cab,
- said suspension means being constructed to accommodate jounce and rebound movement of said cab relative to said frame,
