Abstract

The utility model relates to a five-axle bogie, which solves the problem that the bearing capacity of the common bogie cannot satisfy the demands because the practical transportation capacity demands of wide and large cargo transportation enterprises in the power industry, the metrological industry, the chemical industry, the heavy machinery industry and the like are increased. The five-axle bogie comprises a frame (1). Five wheel sets (3) are installed below the frame (1). Rolling bearing devices (14) are arranged at the two ends of each wheel set (3). An axle box (15) is arranged below each wheel set (3). An outer circular spring (16) and an inner circular spring (17) are arranged above the axle box and on the two sides of each wheel set (3) and are connected with the frame (1). A brake rigging (6) is fixed on the frame (1). A truck center plate (4), a center pin (5) and a side bearing iron (7) are fixed on the frame (1). An adjusting pad is arranged in the side bearing iron. The five-axle bogie can be used as supporting facilities for railway freight traffic.

Description

Five axle bogies

Technical field:

The utility model relates to novel five axle bogies of a kind of railway freight.

Background technology:

For many years, multi axle truck occupy a tiny space in the railway freight traffic of China, because electric power, control industries such as gold, chemical industry, heavy-duty machinery the transport enterprise of wealthy, big goods to the actual demand of transport capacity, multi axle truck before have the defective that the number of axle is few, load-carrying is little can not satisfy heavily stressed requirement.

Summary of the invention:

The purpose of this utility model provides a kind of novel five axle bogies, in order to satisfy the demand of industry counterweights such as electric power, metallurgy, chemical industry, heavy-duty machinery, big goods transport, has designed this bogie truck, and this bogie truck adopts the welded type framework.

Above-mentioned purpose realizes by following technical scheme:

Five axle bogies, its composition comprises: framework, it is right to be connected with five groups of wheels below the described framework of employing Q345E, described take turns to following be that axle box is formed, the axle box suspension gear connect described take turns right, connect truck center plate, center pin and side bearing iron above the described framework, have in the described side bearing iron and foundation brake rigging is installed above adjusting the described framework of backing plate.

Described five axle bogies, described framework is a H type integral solder framework, comprise two curb girders, a cartridge beam is arranged in the middle of the described curb girder, described cartridge beam both sides respectively have a crossbeam to be connected on the described curb girder, there are four end carriages at described curb girder two ends, are welded with two side bearing boxes above the described curb girder, uniform 20 drawing strickle guides below the described curb girder.

Described five axle bogies, described end carriage end connects support beam and fixed pivot seat, opposite side end carriage end connects in order to the fixing brake cylinder flap seat of brake equipment, be welded with 4 pairs on the curb girder lower plane in order to connecting the flap seats of brake equipment, coil spring and outer coil spring in comprising below the described drawing strickle guide.

The beneficial effects of the utility model:

1. the utility model is considered the enterprise practical traffic requirements, it is essential that axle box and drawing strickle guide have suitable gap, therefore axle box composition and drawing strickle guide composition are optimized design, scheme comparison, guarantee the vertical and horizontal gap between axle box and the drawing strickle guide, improved the curve performance of passing through of this bogie truck.

2. the utlity model has 5 axletrees, vehicle load reaches 125 tons, thereby the conveying efficiency height.

3. the utlity model has characteristics such as simple to operate, that working service is convenient.

4. the utility model has adopted Q345E sheet material in a large number, and actv. has increased intensity, alleviated deadweight.

Accompanying drawing 1 is the main TV structure scheme drawing of this product.

Accompanying drawing 2 is plan structure scheme drawings of accompanying drawing 1.

The specific embodiment:

Embodiment 1:

Described five axle bogies, its composition comprises framework 1, five groups of wheels is housed to 3 below the described framework 1, and described to take turns 3 two ends are rolling bearing systems 14, be axle box 15 below, above the described axle box, to be outer coil springs 16 to 3 both sides link to each other with interior coil spring 17 and with framework composition 1 wheel.Foundation brake rigging 6 is fixed on the described framework 1, is fixed with truck center plate 4, center pin 5 and side bearing iron 7 above the framework 1, and the adjustment backing plate is arranged in the side bearing iron.

Described five axle bogies, described framework 1 middle part is a cartridge beam 9, and both sides are two curb girders 8, and two ends are four end carriages 11, one side beam end connects support beam 18 and fixed pivot seat 19, and opposite side end carriage end connects brake cylinder flap seat 20 in order to fixing brake equipment 6; Respectively there is a crossbeam 10 cartridge beam 9 both sides, and crossbeam 10 is connected with curb girder 8; Be welded with fixed pivot seat 21 on the crossbeam of left side; Respectively be welded with bottom side bearing box 12 above two curb girder 8 middle parts; Be welded with 4 pairs of flap seats on the two curb girder lower planes in order to connect brake equipment 6; Uniform 20 drawing strickle guides 13 on two curb girders, 8 lower planes.

This product is applied on the extraordinary flatcar of 450T, and the extraordinary flatcar of 450T uses on full gauge railway, is mainly used in big, heavy goods such as shipment electric power, metallurgy, chemical plant and heavy-duty machinery.
