Tailgate assembly

Abstract

Trucks and other work machines require strong and easily operated and maintained tailgate assemblies. Often, the operating structure of the tailgate assembly requires precise alignment and relatively large clearance space to operate effectively. The operating structure is also commonly under great stresses from the tension and compression forces that power the operating structure to move the tailgate. A tailgate assembly including a tailgate and an; operating structure is provided. The tailgate is attached to a platform in a hinge d manner and allowed to move pivotally with respect to the platform. The operating structure includes a linear actuator and a linking member. The linear actuator is attached to the platform. The linking member has a first end portion pivotally attached to the linear actuator, a fulcrum pivotally attached to the platform, and a second end portion attached to a tracking member. The tracking member is adapted to contact the tailgate and to move vertically with respect to the tailgate. The use of the tracking member helps eliminate stresses and alignment requirements in the operating structure. The linking member may be used in a relatively small clearance space. The tailgate assembly of the present invention is a robust design, suitable to a high stress work machine environment.
