Abstract

The invention belongs to the technical field of rail transit, and particularly relates to a vehicle frame. The vehicle frame comprises a basic frame, the basic frame comprises a main longitudinal beam, a plurality of center pin holes are formed in the main longitudinal beam at intervals, the center pin holes and center pins are arranged in a one-to-one correspondence mode, the lower ends of the center pins movably penetrate through the corresponding center pin holes, the lower ends of the center pins are connected with a swing bolster, and the swing bolster is located below the basic frame. And a plurality of elastic pieces are arranged between the swing bolster and the main longitudinal beam. The stress level of the frame can be improved, and the fatigue life of the frame is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a vehicle frame. Background technique [0002] The suspended rail transit system uses a box-section track beam with an open bottom. The frame runs under the track beam, and the frame and track beam are connected by bogies. [0003] In the prior art, the bolster of the bogie is mostly located above the frame, the upper end of the center pin of the central suspension device moves through the bolster, and the lower end of the center pin of the central suspension device is connected to the vehicle frame located below the bogie. [0004] In the process of realizing the present invention, the applicant finds that there are at least the following deficiencies in the prior art: [0005] The assembly method of the center pin and the frame in the prior art will cause stress concentration at the joint between the center pin and the frame, thereby reducing the overall fatig...
