Body bolster structure for articulated vehicle with swing bolster type bogie

Abstract

The invention discloses a body bolster structure for an articulated vehicle with a swing bolster type bogie. The body bolster structure is characterized in that the body bolster structure is a symmetric structure along the longitudinal center line and is matched with a concave structure of a swing bolster of the articulated bogie, special-shaped beams are U-shaped beams with hollow and concave middles, cover plates are arranged on two sides of each U-shaped beam, connectors are arranged at two ends of each special-shaped beam by means of machining, and holes are formed in U-shaped side edge beams of the special-shaped beams; a lower cover plate is matched with the integral lower portions of the special-shaped beams, a center hole is formed in the lower cover plate and is matched with a traction center pin, the longitudinal left end and the longitudinal right end of the lower cover plate are fixedly connected with a left edge beam and a right edge beam of vehicle chassis, the transversefront end and the transverse rear end of the lower cover plate are fixed to a traction beam and rear-end longitudinal beams, an upper cover plate is matched with the hollow concave portions of the special-shaped beams, a center hole is formed in the upper cover plate and is matched with the traction center pin, reinforcing beams are fixed to positions between grooves formed by the special-shapedbeams and the lower cover plate, and reinforcement upright plates are fixed to positions among the front end of the upper cover plate, the front end of the lower cover plate and U-shaped side edges ofthe special-shaped beams. The body bolster structure has the advantages that the problems of complicated structures of swing bolster type bogies of existing articulated vehicles and existing vehiclechassis and difficulty in butting can be solved by the aid of the body bolster structure; the body bolster structure is simple, practical, safe and reliable and is high in universality.

Description

technical field [0001] The invention relates to a bolster structure for a bolster type bogie hinged vehicle, belonging to the technical field of urban rail vehicles. Background technique [0002] In a train with a traditional structure, each car is supported by two bogies, and the cars are connected by a coupler buffer device. Articulated trains are different in underframe structure and bogie structure, and its main feature is that articulated trains use bolster bogies. According to the layout position, the bolster bogie is divided into bolster power bogie and bolster articulated bogie. A bolster-type articulated bogie is used between vehicles, that is, two adjacent vehicles share one bogie and is located under the passageway; while the front and rear ends of the train use bolster-type power bogies, the traction braking force is first Passed to the center pin, the center pin and the corbel structure are welded together, and then the force is transmitted to the corbel struc...
