Hinged system of low-floor hinged type train or coach

Abstract

The invention relates to a hinged system of a low-floor hinged type train or coach. A front frame and a rear frame are fixedly connected with a rotary plate bearing respectively, and the front end of the front frame and the rear end of the rear frame respectively form a pitch axis. Preferably, each pitch axis comprises a spherical hinge, a spherical hinge installing hole and a spherical hinge fixing base. The spherical hinges can be inserted into the spherical hinge installing holes movably and fixed in the spherical hinge fixing bases. The front end of the front frame and the rear end of the rear frame are respectively provided with the spherical hinge installing holes. Mechanical lock devices are arranged on the front frame and the rear frame symmetrically in the right and the left directions. A super-angle sensing device is arranged on the rear frame. A rotary plate platform is arranged on the front frame, a front adhesive tape is fixedly connected with an adjacent carriage floor, and a rear adhesive tape is fixedly connected with the rotary plate platform and arranged below the front adhesive tape. The hinged system is good in torsion resistance and buffering effect, the front frame and the rear frame respectively form the pitch axis, even if a vehicle is pitched and overturned or moves vertically in a driving process, each pitch axis can move correspondingly, the vehicle can run smoothly without damage, and the hinged system is suitable for massive popularization and application.

Description

technical field [0001] The present invention relates to the technical field of vehicle structures, in particular to the technical field of a pull-type hinged system, in particular to a hinged system for low-floor articulated trains or passenger cars. Background technique [0002] With the rapid development of urbanization, public transportation has higher and higher requirements for passenger capacity, and there are more market demands for articulated passenger cars or trains composed of multiple carriages, such as figure 1 As shown, the vehicle system is composed of multiple carriages.

[0002] With the rapid development of urbanization, public transportation has higher and higher requirements for passenger capacity, and there are more market demands for articulated passenger cars or trains composed of multiple carriages, such as figure 1 As shown, the vehicle system is composed of multiple carriages. Except for the last carriage, each carriage is supported by two supporting bridges, and an articulation system is set between every two carriages. The multi-carriage improves the transportation capacity. It reduces the transportation cost, but it also brings some technical difficulties, such as the vehicle is affected by the environment, and the carriages supported by the two double bridges will appear on different planes (such as figure 2 As shown), at this time, it is necessary to ensure the pitching function of the hinge system and ensure that the vertical displacement of the vehicle is not affected. It is subject to a rotational force caused by the pitching of the hinge system, and at the same time, it is also necessary to ensure that this point can be displaced due to the upward displacement of the vehicle. Obviously, the above-mentioned movement cannot be achieved only by relying on a pitching axis at point A. At this time, the single pitching axis The articulation system cannot provide reasonable pitching and cushioning performance, and the vehicle is easily damaged. This articulation system between double-axle carriages is a technical blank at home and abroad
