Truck hood motion control apparatus

摘要

A hood assembly for a conventional truck includes structure for maintaining alignment of the hood relative to the cab during operation of the truck, structure for sealing the gap between the hood and a cowl of the truck, and a four bar linkage hood motion control apparatus, with or without a secondary pivot which can be activated to increase the degree of forward tilt of the hood. The four bar linkage provides for easy forward tilting of the hood assembly by causing horizontal movement of the hood in the first phase of the opening motion followed by pivoting of the hood toward a vertical position to allow access to an engine compartment therebeneath. The linkage is connected to the hood adjacent the center of gravity thereof and provides a truck tilt hood assembly which is significantly decreased in weight.
