Coupler and frame assembly and highway and railway dual-purpose vehicle

Abstract

A coupler and frame assembly comprises two longitudinal beams arranged in parallel, the two longitudinal beams are connected with each other through a longitudinal beam connecting plate, a lifting airbag mounting seat is arrange between that two longitudinal beams, a position of a lower cover plate of the longitudinal beam corresponding to the lifting airbag mounting seat has a carrier airbag insertion hole, a carrier airbag mount seat is installed in the carrying airbag insertion hole, load-bearing pillow beams are installed on the outsides of the longitudinal beams, a coupler seat is arrangebetween the front ends of the two longitudinal beams, and a tightly connected coupler is installed in the coupler seat through a coupler pin. The invention also discloses a highway-railway dual-purpose vehicle, which comprises the coupler and frame assembly, a suspension with large stroke and a single-axle bogie, wherein the suspension and the single-axle bogie are fixedly installed on the coupler and frame assembly respectively. The coupler and frame assembly 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 coupler and frame assembly 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. "Door to door" transportation. [0003] Due to a relatively late start, the development of my country's transportation and logistics industry has been lagging behind foreign countries, and the realization of railway "door-to-door" transportation equipment is only used in the field of railway container transportation. However, railway container transportation has always been wandering between "door-to-station and station-to-door" transportation, and has not realiz...

AI Technical Summary

Problems solved by technology

[0007] 1. When transporting from road to railway, it is necessary to add one sleeper assembly, two sleeper assemblies and bogies; when transferring from railway to road, it is necessary to remove one sleeper assembly, two sleeper assemblies and bogies, so that Greatly increased transit time

[0008] 2. When the road and railway operation modes are switched between road and railway vehicles, it needs to be carried out in a dedicated site, and the corresponding forklift truck for moving the bogie must be equipped, and the conversion site must have a hardened ballast bed suitable for the length of the vehicle, and the ballast surface and the rail surface The same height and can ease the transition to the ground, and the railway stations that participate in the conversion of public-rail transportation need to set up special assembly and storage sites for traction pillows with bogies. In this way, the number of railway stations that can use public-rail conversion will be greatly reduced. limit
