Abstract

The invention discloses a rail trailer running part which is mounted below a trailer body and comprises an axle, wherein axle box bodies are arranged at the two ends of the axle; an electromagnetic brake is mounted on the outer side of one axle box body; buffer devices are arranged at the upper ends of the two axle box bodies respectively and comprise plate springs; the lower ends of the plate springs are connected with the upper surfaces of the axle box bodies; one end of each plate spring is articulated with a first mounting seat; the other end of each plate spring is articulated with a transition mounting seat; second mounting seats are articulated above the transition mounting seats; and the first mounting seats and the second mounting seats are connected with the trailer bodies. The rail trailer running part is simple structure, light in weight and convenient to assemble and overhaul. The electromagnetic brake allows the trailer running part to have a braking function; a structureof the trailer running part is simplified; the trailer running part is more applicable to a light-weight design of a light rail trailer; and the production and manufacturing cost is lowered. The buffer devices transmit vertical, traction and braking loads between the trailer body and the running part and mitigate an impact load generated by an uneven pavement.

Description

technical field

[0001] The invention relates to the technical field of railway vehicle equipment, in particular to a running part of a rail trailer. Background technique

[0002] Rail trailers are often used as portable low-carrying rail vehicles for transportation equipment. They need to be light in weight, stable in operation, and capable of parking brakes. At present, most of the running parts of domestic rail vehicles have heavy shafts, heavy weights, steel wheel materials, brake cylinders and other structural forms, complex structures, high manufacturing costs, and inconvenient transportation; they cannot be installed on portable rail trailers. More can not satisfy the customer's requirement to the light weight of trailer. With the rapid development of high-speed rail vehicles such as EMUs and high-speed rail vehicles, the requirements for the braking function, structural strength, safety performance and lightweight of the trailer running part are getting higher and hi...
