Abstract
A truck cab (32) is disclosed as having a lower cab component (38) including a unitary, lower member (46) with a rear wall (48), a floor (50), and a toe panel (52), and as also having an upper cab component (40) including a unitary, upper member (66) having a roof (68), a pair of windshield pillars (70), and a cowl (72). An upper connection (42) connects an upper end (54) of the rear wall (48) of the lower cab component to the rear end (74) of the roof (68) of the upper component, and a lower connection (44) connects an upper end (64) of the toe panel (52) to the cowl (72) of the upper cab component. The unitary, lower and upper members (44,66) are disclosed as being made by resin transfer molding, compression molding, or sheet metal forming. With a resin transfer molded lower and upper members, an outer roof panel (104) is also utilized to cover the roof (68) of the upper member (66). The compression molded embodiment also has an outer roof panel (110) covering ribs (108) of roof (68) and having windshield pillar portions (114) connected to a cowl portion (115) to cooperate with the compression molded upper member (66) to provide the requisite strength.
