Embodiment Construction

[0021] The present invention will be further described below with reference to the drawings and embodiments.

[0022] Such as figure 1 , 2 As shown, the primary suspension device of the high-speed freight car bogie of the present invention includes a primary external circular spring 1, a primary internal circular spring 2, a vertical elastic stop 3, an upper axle box 4, and a rotating arm Elastic rubber node 5, one lower axle box 6, one spring mounting support plate 7. Such as figure 1 Shown. The structure can obtain the longitudinal and lateral stiffness values ​​required by the bogie for high-speed operation by adjusting the longitudinal and lateral stiffness of the elastic rubber node 5 of the boom, and realizes the wear-free design of a series of axle box spring suspension system, and a series of external circular springs. 1 and a series of inner circular spring 2 are placed on the top of the upper axle box 4, so that the elastic rubber node of the arm 5 will not be subjecte...

Abstract

The invention discloses a single-stage suspension device for a bogie of a high-speed rail wagon. The device comprises a rocker arm type shaft box, wherein one end of the shaft box is connected with a wheel set, and the other end of the shaft box is connected with a framework through a rocker arm elastic rubber pitch point; the rocker arm type shaft box has a separated type positioning structure; and the positioning structure of the rocker arm type shaft box specifically comprises an upper shaft box and a lower shaft box which are in butt joint with each other up and down. By the suspension device, the requirement that the highest shaft weight is 18t when the highest speed of the wagon is 200km / h can be met; and the suspension device has the remarkable characteristics of simple structure, convenience for maintenance and reliably performance.

Description

Technical field [0001] The invention relates to a primary suspension device of a railway freight car bogie, in particular to an axle box primary suspension of a high-speed railway freight car bogie. Background technique [0002] At present, railway freight car bogies generally have three-piece freight car bogies and frame type freight car bogies. The suspension system adopted by the three-piece freight car bogie adopts the central suspension, which is located between the bolster and the side frame, which causes The unsprung mass is too large, and the damage to the line is large, and its operating speed will not exceed 120km / h. The suspension system of the frame-type freight car bogie basically adopts a series of axle box suspension. Chinese patents ZL01275171.5 (publication number CN 2517641Y), ZL200620034959.8 (publication number CN 200945865Y), ZL200720063538.2 (publication number CN201068149Y) respectively A "high-speed freight car bogie", a "fast railway freight car bogie", ...
