Abstract
The invention belongs to the technical field of friction damping devices for rail wagons, particularly relates to a combined holder body and aims to solve the problems of unstable friction coefficient, influence on safe and stable operation of a wagon and inconvenience in maintenance of the conventional holder body. The combined holder body comprises a holder body, wherein a friction plate which is in interference fit with the holder body is embedded into the side face of the holder body; and the center of the surface of the friction plate is provided with a full-length groove. The invention has the advantages that: the combined holder body has stable friction coefficient, enhances wear resistance, prolongs overhaul period and lowers overhaul workload; repair welding processing performed after the wear of the conventional metal component can be avoided, wear limit can be judged according to a wear limit mark, great convenience is brought to overhaul and maintenance, the conventional maintenance mode is changed fundamentally, maintenance efficiency and quality are improved and requirements on part repair and repair based on condition can be met; simultaneously, compared with a metal material with the same size, the device has the advantages of low density and light weight.
Description
Technical field
The invention belongs to the technical field of railway freight-car friction damping device, be specifically related to a kind of combined type holder body.
Background technique
The vibration insulating system of railway goods train bogie is to reduce its Oscillation Amplitude and vibration frequency by the fricting movement between the parts with frication pair in this system, reaches the purpose of safety and steady operation.The essence of this system's damping effect is that the friction by friction pair makes mechanical vibration be converted into heat energy or surface chemistry energy and finally absorbs or distribute.So parts with frication pair is the crucial Component that influence the operation of lorry safety and steady, require stable friction factor, friction layer antifriction and maintenance easily.After the railway speed-raising truck, Vehicular vibration sharply increases.Therefore, railway speed-raising truck has proposed requirements at the higher level to the lorry vibration damper.
The holder body is the friction damping parts of railway freight-car Li Nuoer vibration damping equipment, the former steel that is designed to No. 45, and the influence of its rubbing surface bits that rub on a small quantity, gravel and dirt etc. of being invaded at work, the friction factor instability influences the operation of lorry safety and steady; Though Quenching Treatment has been passed through on its surface, because the abrasion of the friction pair of steel to steel are bigger, the wear resistance of its friction layer can not satisfy usage requirement, causes the vibration damper damping property to descend, even inoperative in the long-term back of using.In addition, holder body wearing and tearing back is adopted restive quality such as soldering processing and is damaged the traditional maintenance method of body, is inconvenient to overhaul and safeguard, influences maintenance efficiency and quality, and incompatibility is changed the requirement that part is repaiied, state is repaiied.
Summary of the invention
The present invention to have holder body friction factor instability now in order solving, to influence the operation of lorry safety and steady, and the problem of being inconvenient to keep in repair, and a kind of combined type holder body is provided.
The present invention adopts following technological scheme to realize:
Combined type holder body comprises holder body body, and the side that it is characterized in that holder body body is inlaid with the friction plate with holder body body interference fit, and friction plate centre of surface place has elongated groove.
Friction plate is made up of friction layer, adhesive layer and enhancement layer three parts, and described friction layer adopts phenol-formaldehyde resin modified, and enhancement layer adopts galss fiber reinforced resin, and adhesive layer adopts organic binder.Friction plate is provided with the mark that may wear to limit.
The present invention has following beneficial effect: adopt the polymer composite friction plate, stable friction factor has improved wear resistance, has prolonged the repair cycle, has reduced maintenance workload; Can avoid the soldering processing after original metal parts weares and teares, whether wear away limit by wearing away the limit marker for judgment, be very easy to maintenance and maintenance, fundamentally changed the traditional maintenance mode, improved maintenance efficiency and quality, can adapt to and change the requirement that part is repaiied, state is repaiied.Simultaneously, compare, have that density is little, the advantage of light weight with the metallic material of equal volume.
