Problems solved by technology

[0005] 1. The ability of a series of shock-absorbing spring components to reduce vibration is limited, resulting in poor vehicle stability indicators, and the safety of goods and the comfort of personnel cannot be guaranteed;
[0006] 2. The car body and the wheelset cannot rotate relative to each other around the vertical (vertical direction), resulting in weak vehicle curve passing ability, and the vehicle cannot pass through small-radius curves, which cannot be used on most routes

Abstract

A single-axle bogie comprises a frame with axle boxes mounted on the bottom surface; a wheel axle assembly is arranged between the two axle boxes, a series of vibration-absorbing spring assemblies aredisposed between the axle boxes and the frame; a brake assembly is mounted on the bottom surface of the frame; a mandrel pin is arrange in the center of the top surface of the frame, and both ends ofthe top surface of the frame have frame connecting assemblies; the frame connecting assembly comprises a frame connecting plate with a frame limit connecting seat in the center, a frame connecting long hole is longitudinally formed in the top surface of the frame limit connecting seat, an H-shape connector is inserted into the frame connecting long hole, longitudinal two ends of the frame connecting plate are clamped with secondary rubber spring assemblies; the secondary rubber spring assemblies comprise secondary rubber spring mounting plates and secondary rubber springs, the lower ends of the secondary rubber springs are clamped on the frame connecting plates, and the upper ends of the secondary rubber springs are vulcanized on the secondary rubber spring mounting plates. The highway and railway dual-purpose vehicle comprises a frame, a suspension with a large stroke and the single-axle bogie, wherein the suspension and the single-axle bogie are fixedly mounted on the frame respectively. The single-axle bogie is applicable to both road and rail vehicles.

Description

technical field [0001] The invention relates to the field of road transportation, in particular to a single-axle bogie and a road-rail vehicle. Background technique [0002] With the development of transportation capacity, cargo owners have higher and higher requirements for the timeliness of cargo delivery. The railways of various countries are constantly committed to improving the speed of cargo delivery, striving to form the speed advantage of cargo delivery, and gradually form container transportation. The "door-to-door" transportation, the road-rail vehicle is one of the important equipment to realize the "door-to-door" transportation. [0003] The road-rail vehicle has functional modules related to both railway and road driving. The shape of the vehicle is also limited by the shape of the railway and road, and the internal structure of the vehicle is compact. The single-axle bogie is an ideal railway driving function component for road and railway vehicles due to its ...
