Auxiliary framework type radial bogie suitable for various foundation brake devices

Abstract

The invention discloses an auxiliary framework type radial bogie suitable for various foundation brake devices. The auxiliary framework type radial bogie consists of a wheel set assembly, a side frame assembly, a rubber pile, a swing bolster assembly, the foundation brake devices, a rolling bearing device, a wheel set radial device, a central suspension device and an elastic side bearing assembly. The wheel set radial device is formed by a pair of U-shaped auxiliary frameworks; four groups of anti-falling mounting bases are arranged on the auxiliary frameworks and are connected above the round pins, and anti-falling bolts, nuts, gaskets and cotter pins are mounted in the anti-falling mounting bases; and a structural arm of the auxiliary framework is of a concave solid structure. The adaptability of the swing bolster is improved and the light weight is realized by optimally designing the assembly hole of the abdomen brake device of the swing bolster; the auxiliary framework part adopts a variable cross-section solid design to meet the assembling clearance requirements of various brake devices, and the application is reliable; according to the auxiliary framework type radial bogie suitable, the characteristics of low power, low abrasion, excellent curve passing capacity and the like of the bogie are guaranteed, and it is also guaranteed that the bogie can be provided with different basic braking devices.

Description

technical field [0001] The invention belongs to the field of design and manufacture of railway transportation devices, in particular to the structural design and manufacture of railway vehicle bogies, and relates to the matching design of railway freight car bogies and foundation braking devices, specifically a sub-frame type suitable for various foundation braking devices. Radial bogie. Background technique [0002] According to domestic and foreign freight vehicle market demand, customers have gradually increased requirements on bogie structure and performance. Most customers require bogies with low power, low wear and integrated braking devices, and sub-frame radial bogies can meet their requirements. Require. However, due to the limitation of the sub-frame bogie structure, the layout of the foundation brake device of the existing bogie is relatively simple, especially the structure type of the sub-frame and the structure of the fish belly assembly hole of the bolster ca...
