Abstract
A frame bracket for mounting a trailing arm to a trailer frame in a trailing arm suspension system comprising a U-shaped frame having a front wall and two side walls, a combined stiffener and gusset having a stiffening portion extending between the U-shaped frame side walls, and a gusset portion extending outwardly from at least one of the U-shaped frame side walls and adapted to mount to the trailer frame to provide additional stiffening, and an attachment flange curving inwardly from an upper edge of at least one of the front and side walls of the U-shaped frame; whereby a weld may be placed between the attachment flange and the trailer frame which is substantially in line with the at least one front or side wall having the attachment flange.
Claims11
A mounting bracket assembly for mounting a trailing arm to a vehicle frame in a trailing arm suspension system, the mounting bracket assembly comprising:
- a side frame having a front plate and two side plates extending substantially parallel to each other from the front plate;
- and
- a one-piece rear gusset having a brace portion and a stiffening portion, the stiffening portion extending obliquely from the brace portion and sized to fit in a space between the side plates and welded thereto, and the brace portion having a laterally extending portion extending laterally of the space between the side plates, said laterally extending portion of said brace portion having an interior edge extending along one of said side plates and being secured thereto, and a top edge adapted to be secured to the vehicle frame wherein said brace portion laterally extending portion extends laterally of said one of said side plates and extends between said one of said side plates and said vehicle frame when the mounting bracket assembly is assembled to the vehicle frame.
A vehicle suspension having a mounting bracket mounting a trailing arm suspension to a vehicle frame, said mounting bracket comprising a front plate and two side plates extending substantially parallel to each other from the front plate, each of said front and side plates welded directly at upper portions thereof to the vehicle frame without a panel therebetween, the improvement comprising:
- at least one of said front and side plates being deformed laterally at an upper portion thereof and terminating in a terminal edge adjacent a side of said at least one plate to form a gap between an outer surface of the deformed portion and the vehicle frame;
- the deformed portion being secured to the vehicle frame by a weld in the gap, the weld being disposed above the at least one plate wherein moments about said weld between said at least one plate and said frame due to vertical loads on the mounting bracket are minimized;
- and
- a rear gusset having a stiffener portion and a brace portion, said stiffener portion extending obliquely from the brace portion and between the side plates, and welded thereto, said brace portion extending away from one of the side plates and having a portion thereof welded to the vehicle frame.
