Abstract
The invention relates to a mounting structure for brake pads of a motor train unit, which comprises an arc-shaped large steel backing and a spring clamp. The large steel backing comprises a base plate and vertical plates, and the base plate of the large steel backing comprises a spherical surface groove, brake pad through holes and fastener grooves. The invention further provides a brake pad mounting method, which is used for mounting brake pads by the aid of the mounting structure. The mounting structure for the brake pads of the motor train unit adopts a mounting mode which leads a brake pad friction surface to realize self adjustment, so that the brake pads on the steel backing are ground in place advantageously as soon as possible and can be tightly attached onto a brake disc in a braking process, the structure is simple, and cost is reduced.
Description
Technical field
The present invention relates to a kind of mounting structure of rail motor set brake pad, belong to the train braking system field.
Background technique
Powder metallurgy friction material is to be matrix with metal and alloy thereof, adds friction constituent element and lubricant component, the composite material of processing with powder metallurgy process.Powder metallurgy friction material has enough intensity, suitable and stable friction factor, and stable working is reliable, and is wear-resisting and pollute advantages such as few, is to use one of material more widely in the modern braking material family.
Present China rapid economic development, the railway passenger and freight transport volume increases sharply, and the speed up of railway transport has become inevitable development trend.China has opened the above EMU train of speed per hour 300km at present.The train speed up is had higher requirement to the brake pad that braking system has very high requirement, particularly braking system, and wherein technology is the most ripe, most widely used is the powder metallurgy brake pad.
The brake lining that powder metallurgical technique is processed is assembled on the brake plate support, refills to be fitted in the braking system.In order to make the brake lining reliable contact brake disc in braking process that is installed on the brake plate support, the arrangement of brake lining on brake plate support keeps appropriate gap.And in order to make brake lining held stationary in braking process, brake lining all is designed to definite shape.Existing brake lining shape comprises circle, Hexagon, triangle or the like.
Brake lining and steel backing generally adopt technologies such as riveted joint, welding to realize at present.This method is for the friction material and the middle low speed train of routine, because the friction material wear resistance is general, can in use reach the degree of break-in quickly.But development along with bullet train; The wear resistance of friction material increases substantially; Therefore need the installation of a kind of brake lining and steel backing to realize a kind of brake lining adjustment mode; The brake lining that is beneficial to be installed on the steel backing realizes that as soon as possible break-in puts in place, and in braking process, can closely fit on the brake disc.
Summary of the invention
The present invention provides a kind of mounting structure of novel rail motor set brake pad, is used to overcome above deficiency.
The mounting structure of rail motor set brake pad of the present invention comprises the big steel backing and the spring clamp of arc, and big steel backing comprises substrate and riser, and big steel backing substrate comprises spherical groove, brake lining via hole and fastener recess.
The present invention also provides a kind of installation method of brake lining, is used for realizing utilizing mounting structure of the present invention that brake lining is installed.Installation method of the present invention comprises, the brake lining via hole that makes the fastening connection piece of brake lining pass big steel backing gets into fastener recess, utilizes spring clamp that brake lining is fastened on the substrate of big steel backing.
Powder metallurgy brake lining mounting structure of the present invention is a kind of mounting type that makes brake lining rubbing surface oneself adjustment; The brake lining that is beneficial to be installed on the steel backing realizes that as soon as possible break-in puts in place; And in braking process, can closely fit on the brake disc, relatively simple for structure, cost reduces.

Embodiment
The present invention is described with reference to the accompanying drawings.
The mounting structure of powder metallurgy brake lining of the present invention; The big steel backing 1 and spring clamp 3 that comprise arc; Big steel backing 1 comprises substrate 101 and riser 102,102 ', 103,103 '; The substrate 101 of big steel backing 1 also comprises a plurality of brake linings installation position, and each installation position comprises spherical groove 105, brake lining via hole 106 and fastener recess 104.
Brake lining mounting structure of the present invention is when installing brake lining; The brake lining via hole 106 that makes the fastening connection piece 23 of brake lining 2 pass big steel backing gets into fastener recess 104; Utilize spring clamp 3 brake lining 2 to be fastened on the substrate 101 of big steel backing, the elasticity of spring clamp 3 makes the steel backing sphere 21 of brake lining be adjacent to spherical groove 105.
Powder metallurgy brake lining mounting structure of the present invention is the mounting type that makes brake lining rubbing surface oneself adjustment; Through the sphere of brake lining steel backing and the spherical groove of big steel backing substrate; Make brake lining with brake disc applying process in can realize rubbing surface direction adjustment; Thereby the rubbing surface of brake lining contacts brake disc as much as possible, and the brake lining that is beneficial to be installed on the steel backing realizes that as soon as possible break-in puts in place, and in braking process, can closely fit on the brake disc.
