Поясная тележка Improved archbar bogie with all metallic elements, welded bolster and combined suspesion of coiled and elliptical leaf springs
Improved archbar bogie. The first Archbar bogies were built in 1898 at the Mytishchi Carriage Works for freight cars of the former Moscow-Ryazan-Kazan Railway. Subsequently, their design was improved, and they were used for many years on all types of four-axle freight cars. The belt bogie (Fig. 83) consists of two assembled longitudinal side frames, two wheelsets with axle boxes with bearings mounted on the axle necks, two spring assemblies, a spring beam, a spring beam, and a lever brake transmission. Each side member is assembled from three steel belts: upper 1, middle 4, and lower 5. In the middle part of each side member, between the upper and middle belts, there are two cast steel hollow columns 2 through which bolts 3 pass, tightening all three belts. The columns also serve as guides for the upper crossbar 9 when it is moved vertically; the bracket for the brake shoe hangers is cast onto them. At the ends of the side frame, between the middle and lower belts, there are axle boxes. The belts, together with the axle boxes, are tightly fastened with axle box bolts 6 with crown nuts. Both side frames of the bogie are connected to each other by a cross tie 8, located on the middle belts between the columns and held by plates welded to the lower surface of the tie. At the ends of the cross member there are metal pallets on which spring assemblies 7 are installed. Each set consists of four cylindrical springs and one elliptical spring or four and five double-row cylindrical springs (for older belt trolleys). As part of modernization, 4- and 5-spring spring sets have been replaced with an improved (standardized) spring set consisting of three cylindrical springs arranged in a row and an elliptical spring.
A bolster is laid across the bogie on top of the spring sets. Previously, bogies had box-section beams of riveted and welded construction. With the introduction of reinforced bogies and bogies with cast sidewalls, a cast steel over-spring beam was used, which is distinguished by its greater strength and wear resistance compared to the beams previously used.
