ABSTRACT:
Disclosed is a level load spring axle assembly for trailers and the like which has a main shaft rotatably mounted on the frame of a vehicle by a pair of spaced bearing brackets. A pair of parallel extending spaced crank arms are fixed to each end of the main shaft on either side of each of the bearing brackets. The crank arms extend transverse to the length of the main shaft. Wheel spindles are mounted to extend parallel to the main shaft from each of the outer crank arms. A spring follower is rigidly coupled between the crank arms coaxial with the wheel spindles. A leaf spring is attached to the bearing brackets which in turn may be attached to the frame of the vehicle. The spring is narrower in width than the space between the pairs of crank arms. The spring has a first portion which extends away from the main shaft and a second curved portion which extends from the end of the first portion back in a direction toward the main shaft. A third portion extends from the second portion and forms a hook of a size to engage the spring follower pin.
