Abstract
A bogie for use with a railway wagon, comprising a rigid horizontal frame adapted to be vertically pivoted to the underside of the wagon by a central vertical pivot, also with the interposition of a large diameter ball bearing assembly, co-axial with the pivot and positively maintaining the frame parallel to the bottom of the wagon. Rail-engaging wheels are each supported below the frame by an independent suspension assembly. Each of the latter comprises a pair of lever arms extending on both sides of the associated wheel and pivoted at one end to the frame and rigidly interconnected at their opposite ends by a cross-member. The wheel is rotatably carried by the intermediate portions of the two arms. An elastic suspension member extends vertically between the frame and the cross-member. The main parts of the bogie are of welded box-like construction formed of metal plates. The wheels can be easily dismounted for repair or replacement.
