Abstract
Improvements in a suspension arm for a land vehicle. The suspension arm is an A-Frame box suspension arm to be essentially fabricated from sheet metal. The sheet metal members are fabricated to the desired shape and then some members are bent. The top and bottom plate members to be keyed. The keyed members both position the components and minimize or eliminate the need for a fixture that holds the parts while they are being welded together. The driver and passenger suspension arms flipper or mirror images. This allows both the left and right sides of the vehicle to utilize the same suspension arm. The box structure transfers loads along the multiple wall structures of the suspension arm when loads are encountered by the wheels and then transferred into the frame. The suspension arms are used in off-road and on-road vehicles for transportation.
