Abstract

The utility model relates to a railway freight car bogie for meter-gauge lines, which comprises a bottom bolster and a foundation brake rigging, the bottom bolster is provided with a lower center plate integrated with the bottom bolster, and the railway freight car bogie solves the inertial mass problem that the bolts of the lower center plate can be easily loosened and broken. Because both ends of the lower center plate are respectively provided with a safe lifting lug which can prevent throwout caused by derail, the train body can be prevented from being separated from the bogie when the train derails, and hazards caused by derail can be reduced. Because cast iron gapped lower side bearings are arranged in the side bearing boxes of the bottom bolster, the curve passage capability and twisted line adaptability of a car can be enhanced, and the manufacturing and maintenance costs are low. Because a brake beam in the foundation brake rigging adopts an integrated weldless structure, fatigue cracks caused by welding are avoided, and the inertial mass problem of the failure of the brake beam caused by cracks is solved. Because a lower pull rod safety hanger is arranged on the brake beam, running accidents caused by the separation of the brake beam are prevented, and thereby the running safety of the car is improved. The utility model has the advantages of simple structure, convenient maintenance and low production and maintenance costs.

Description

Rice path road railway goods train bogie

Technical field

The utility model relates to a kind of railway goods train bogie, especially a kind of meter path road railway goods train bogie.

Background technology

At present, the China railways circuit gauge overwhelming majority is 1435mm (standard gauge), only also has the rice path road of a spot of 1000mm within the border in Yunnan Province of China, and abroad, rice path road mainly is distributed in Southeast Asian countries and African country.Bogie truck is as the critical component of rolling stock, and the quality of its performance directly affects the riding quality and the safe in operation of vehicle.Owing to politics, the many-sided reason of economic dispatch, the vehicle technology level on these meters path road is lower, show that mainly vehicle load is few, bogie axle is heavily little, running velocity is low, its reason is these meters rail roller bearing adapter stabilizer bar poor-performing, when vehicle derailing, can not prevent separating between car body and bogie truck.

Summary of the invention

The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, axle is great, running velocity is higher, curve negotiation ability is better and have the roller bearing adapter stabilizer bar that is applicable to meter gage railway that anti-derailing throws away function.

For achieving the above object, the utility model adopts following technical proposals:

A kind of meter path road railway goods train bogie comprises bolster and foundation brake rigging, and described bolster is provided with it and is the truck center plate of one, and the both sides of truck center plate are provided with safe hanger, are provided with cast iron gap bottom side bearing in the side bearing box of bolster; Brake beam in the foundation brake rigging is integral type, solderless access node structure, and the lower link safety jaw is set on brake beam.

Described bolster and truck center plate adopt inblock cast or are welded to connect.

The utility model has the following advantages compared with prior art:

1, be provided with on bolster and have the safe hanger that anti-derailing throws away function, reduce the harm that derailing brings separating between car body and the bogie truck when preventing derail.

2, adopt truck center plate and bolster integral structure, solved the inertial mass problem that the truck center plate bolt becomes flexible easily, fractures.

3, adopt cast iron gap bottom side bearing, improve the adaptive capacity of the curve negotiation ability and the distortion circuit of vehicle, manufacturing and maintenance cost are lower.

4, the brake beam in the foundation brake rigging adopts integral type, solderless access node structure, has avoided the endurance crack that causes because of welding, has solved the inertial mass problem that brake beam lost efficacy because of crackle.The lower link safety jaw is set on brake beam, prevents the train operation accident that comes off and cause because of brake beam, improved the safe in operation of vehicle.

5, bogie truck can satisfy the vehicle performance requirement, and simple in structure, to be convenient to maintenance, production and maintenance cost lower.

Among the figure: 1, wheel is right, and 2, bogie side frame, 3, bolster, 4, foundation brake rigging, 5, bolster central mounting vibration insulating system, 6, bearing arrangement, 7, adapter, 8, bottom side bearing, 9, cartridge abrasion dish, 10, side bearing box, 11, truck center plate, 12, safe hanger, 13, car body safety hanger, 14, brake beam, 15, the brake beam slide block, 16, the lower link safety jaw.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 2 and shown in Figure 3, rice of the present utility model path afloat car bogie truck is the same with traditional three piece truck, comprises that two wheels are to 1, two bogie side frame 2, bolster 3, foundation brake rigging 4, bolster central mounting vibration insulating system 5, four bearing arrangements 6, four adapters 7, two bottom side bearings 8, cartridge abrasion dish 9 and two safe hangers 12.Side frames 2 and four adapters 7 are formed integral seats and are dropped on two wheels having four bearing arrangements 6 on 1, a bolster 3 drops on two bogie side frames 2 by two bolster central mounting vibration insulating systems 5, foundation brake rigging 4 is installed on the bogie side frame 2 by the brake beam slide block 15 at brake beam 14 two ends, two bottom side bearings 8 are placed in the side bearing box 10 of bolster 3, bottom side bearing 8 is a cast iron gap side bearing, adopt this structure can improve the curve negotiation ability of vehicle and the adaptive capacity of twisting circuit, by optimizing the gap of 2 of adapter 7 and sides, bolster central mounting vibration insulating system 5 is realized the coupling of bogie truck running velocity and curving performance.Cartridge abrasion dish 9 is placed in the truck center plate 11 on the bolster.

As shown in Figure 4, two safe hangers 12 are arranged on the bolster 3, are positioned at the both sides of truck center plate 11.Two safe hangers 12 by with car body on two car body safety hangers 13 to connection, make car body link to each other with bogie truck, when preventing derail, bogie truck separates with car body.Truck center plate 11 and bolster 3 cast solid formula structures have solved the inertial mass problem that the truck center plate bolt becomes flexible easily, fractures; Bolster 3 can be the inblock cast form with being connected of truck center plate 11, also can be Type of Welding.

As shown in Figure 5, the brake beam 14 in the foundation brake rigging 4 adopts integral type, solderless access node structure, at the middle part of brake beam 14 lower link safety jaw 16 is set, and has improved the service life of brake equipment and the safe in operation of vehicle.

All the other structures then adopt routine techniques.
