Intermediate articulated bogie with small-curve negotiation capability of six-axle high-floor light rail vehicle

Abstract

An intermediate articulated bogie with small-curve negotiation capability of a six-axle high-floor light rail vehicle comprises a bolster device, a framework device, two wheelset devices, axle box devices, basic braking devices and a rotary device, wherein the bolster device is mounted on the framework device; a plurality of primary suspension devices are mounted at the bottom of the framework device; the axle box devices are separately arranged at the end parts of the two wheelset devices; the axle box devices are connected to the primary suspension devices; the basic braking devices are mounted on the wheelset devices; the rotary device is mounted on the bolster device; and the rotary device comprises a center pin rubber sleeve, a lower friction disk and an upper friction disk which arearranged on the center pin rubber sleeve in a sleeving mode, a center pin inserted in the center pin rubber sleeve, a lower articulated device connected to the center pin, and an upper articulated device connected to the lower articulated device through a spherical plain bearing. The intermediate articulated bogie has the advantages of simple structure, light weight, low cost, controllable rotaryresistance and wide application range.

Description

technical field [0001] The invention belongs to the technical field of bogies for rail transit vehicles, and in particular relates to a non-powered intermediate articulated bogie shared by two adjacent car bodies of a six-axle high-floor light rail vehicle with small curve passing capacity. Background technique [0002] Existing large and medium-sized subway vehicles generally require the minimum curve radius of the main line track to be between 300-350 meters, adopt all-steel wheels, and have an axle weight of about 14 tons to 16 tons, with large transportation volume, high noise, and high construction costs. It is not suitable for the operation of urban elevated and ground lines, so it is not suitable as a backbone rail transportation tool for small and medium-sized cities. The six-axle high-floor light rail vehicle uses rubber elastic wheels with an axle load of about 10.5 tons to 12.5 tons, which can pass through the main line curve radius of 25 to 50 meters, reducing th...
