Mounting seat for hinged mechanism of low-floor tram

Abstract

The application discloses a low-floor rail car hinged mechanism mounting seat, which includes a car body mounting plate and a hollow trapezoidal connecting column. The trapezoidal connecting column includes a trapezoidal upper base plate, a trapezoidal lower base plate, a support plate and an I-shaped support column; The shape of the trapezoidal connecting column is a parallelogram. Viewed from the side of the support plate or from the side of the I-shaped support column, the projection of the trapezoidal connecting column is a parallelogram; The mounting surface of the hinge mechanism, each mounting surface of the hinge mechanism is respectively provided with a bolt mounting hole. After adopting the above structure, it can be cast as a whole, and after optimized analysis and design, it can meet the bearing requirements. At the same time, it has the advantages of simple and compact structure design, low manufacturing cost, convenient installation and maintenance, light weight, and high installation fit. It will be widely used in the rail transit field and has a good market prospect.

Description

technical field [0001] The present application relates to a hinge mechanism mounting seat structure, in particular to a low-floor tram hinge mechanism mounting seat. Background technique [0002] Modern low-floor trams adopt a short body module design in order to meet the needs of passing through small radius curves, and the modules are connected by hinge mechanisms. The hinge mechanism bears the weight of the vehicle and the traction and braking force of the vehicle. At the same time, by restraining and releasing the degree of freedom between the vehicle modules, the vehicle can pass through the small radius curve smoothly and quickly to ensure the smooth operation of the vehicle. Therefore, the hinge mechanism is the preferred choice for low-floor trams. The key components. [0003] Because the mounting base for installing the hinged mechanism bears the complex dynamic load of the hinged mechanism, strong bearing capacity is the first requirement. The existing hinge mech...

AI Technical Summary

Problems solved by technology

The existing hinge mechanism mounting seat is divided into two parts, welding and casting. Although the bearing capacity is sufficient, there are disadvantages such as complex structural design, troublesome manufacturing process, and inconvenient installation and maintenance.

[0004] In addition, in the existing articulation mechanism, because the damper of the articulation mechanism has an inclination angle of about 7 degrees from the horizontal plane, the position of the end connecting the mounting seat to the articulation mechanism is high, while the position of the end connecting the mounting seat to the vehicle body module is opposite. Low, the phenomenon that the installation fit is difficult
