Abstract

The invention provides a bogie for a track maintenance machine and the track maintenance machine. The bogie for the track maintenance machinery comprises a framework, a swing bolster, a swing bolster platform, a lifting rod and a traction pull rod, wherein the side bearing and a central pin seat are arranged on the swing bolster; the side bearing is in contact with a train body so as to support the train body; the central pin seat is provided with a vertical pin hole; a central pin of the train body is threaded in the pin hole; the swing bolster platform is arranged at the bottom of the swing bolster; a first spring device, which is vertically arranged, is connected between the swing bolster platform and the swing bolster; the lifting rod is vertically arranged, connected between the swing bolster platform and the framework and is used for enabling the swing bolster platform to swing relative to the framework; and the traction pull rod is arranged in a longitudinal direction of the framework and is connected between the swing bolster and the framework. According to the invention, the stability and comfort of the track maintenance machine during high speed running can be improved.

Description

technical field [0001] The invention relates to track equipment technology, in particular to a track maintenance machinery bogie and track maintenance machinery. Background technique [0002] Track maintenance machinery is an indispensable track tool in the initial stage of railway construction and formal operation. With the rapid development of high-speed railways, the demand for track maintenance machinery used in high-speed railways is increasing. [0003] The bogie is one of the important components of road maintenance machinery, which plays the role of supporting the car body and ensuring the safe operation of the vehicle. Bogies usually include wheel sets, axle boxes, frames and other components, and the frames are connected to the car body through suspension devices. [0004] Since the existing bogies for road maintenance machinery have poor dynamic performance when running at high speed, the road maintenance machinery has poor stability and comfort when running at ...
