Abstract

The invention discloses a radial bogie mechanism, which relates to the technical field of locomotive vehicle structure design, and can effectively solve the problems existing in the radial bogie mechanism in the form of an existing sub-frame. One end of the left front tie rod is hinged on the left front axle box, and the other end is hinged on the left end of the front crossbeam. One end of the right front tie rod is hinged on the right front axlebox, and the other end is hinged on the right end of the front crossbeam. Hinged to the left end of the rear beam, one end of the right rear tie rod is hinged to the right rear axle box, the other end is hinged to the right end of the rear beam, the front beam is hinged to the left of the center of the frame, the rear beam is hinged to the right of the center of the frame, the front beam It is connected with the coupling rod between the rear beams, so as to realize the linkage between the wheel sets. When the bogie passes through the curve, each wheel set tends to the radial position, which is beneficial to reduce the angle of attack between the wheel rim and the rail, thereby reducing the wear of the wheel rim and improving the adhesion of the rolling stock on the curve. It is mainly used for the bogies of locomotives or freight cars.

Description

technical field [0001] The invention belongs to the technical field of locomotive and vehicle structure design, in particular to the technical field of design and manufacture of locomotive and vehicle bogies. Background technique [0002] During the operation of railway rolling stock in the curved section, the wheel-rail creep force realizes the radial occupation of the wheel set on the curve through the radial adjustment mechanism, which can effectively reduce the wheel-rail friction and wear. The radial bogie in the form of sub-frame The more famous ones are the Scheffel bogie in South Africa and the HTCR radial bogie in the United States. Please refer to the article "Unconventional BogieDesigns-Their Practical Basis and Historical Background" and the radial bogie disclosed in Chinese patent CN03148641.X. These two types of bogie The direction of use is different. Since there is no good independent property right of radial bogies in my country, it needs to be authorized b...
