Abstract

The invention discloses a bogie for a passenger car. The bogie comprises a framework system, a wheel set axle box system, a primary suspension positioning system, a secondary suspension system, a central traction device and a basic braking system, wherein the primary suspension positioning system adopts rocker arm type positioning; a positioning rocker arm is fixedly connected with the wheel set axle box system through a clamping band; one end of a vertical shock absorber of the positioning rocker arm is connected with the positioning rocker arm; the other end of the vertical shock absorber is connected with a shock absorber support of the framework system; and split type elastic nodes are installed in node holes of the positioning rocker arm and connected with a node support installed in the framework system through tapered pins and connection bolts. According to the bogie for the passenger car, optimal configuration of the bogie structure and the suspension positioning damping system is carried out, so that the bogie is stable in performance, simple and reliable in structure, light in weight and low in cost, can meet the requirements for high speed and heavy load, and can also guarantee excellent stability, safety and comfort of the bogie during high-speed operation.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a passenger car bogie. Background technique [0002] Some existing bogies include frame, wheel set, primary suspension device, secondary suspension device, traction device and foundation braking device; wherein the beam and side beam of the frame are welded together through a connecting seat, and on the side beam In addition, a brake hanger is welded; the wheel set is formed by pressing the wheels at both ends and the solid axle in the middle; the primary suspension system adopts the combination of spiral steel spring + rotating arm rubber joint + rubber pad; the secondary suspension device adopts air spring +Anti-rolling device+Hydraulic height adjustment device, also equipped with a transverse shock absorber; traction device adopts a single-rod push-pull structure. [0003] The disadvantages of this structure are: the frame carries the traction and braking force through ...
