Abstract
The invention relates to a mounting structure for powder metallurgy brake pads of a high-speed train, which comprises an arc-shaped large steel backing, small triangular supports and a spring clamp. The large steel backing comprises a base plate, four vertical plates and six groups mounting positions for the small triangular supports, each group of mounting positions comprises a spherical surface groove, a guiding hole, a positioning hole, three brake pad through holes and a fastener groove, and each small triangular support comprises a spherical surface, a guiding column, a positioning column and a brake pad spherical surface groove. The mounting structure for the powder metallurgy brake pads of the high-speed train adopts a floating mode so as to be favorable for realizing that the brake pad mounted on the steel backing is ground in place as soon as possible, and can be tightly attached onto a braking disc in a braking process.
Description
Technical field
The present invention relates to a kind of mounting structure of high speed train powder metallurgy brake lining, 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 bullet 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 ralocatable 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 high speed train powder metallurgy brake lining, is used to overcome above deficiency.
The mounting structure of high speed train powder metallurgy brake lining of the present invention; Comprise the big steel backing and the leg-of-mutton little triangle holder of arc; Big steel backing comprises a substrate and four risers; Big steel backing also comprises the installation position of 6 groups of little triangle holders, and every group of installation position comprises spherical groove, guide hole, positioning hole and 3 brake lining via holes and fastener recess, and little triangle holder comprises sphere, leads a post, locating column and brake lining rounded channels.
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.
Powder metallurgy brake lining mounting structure of the present invention is a kind of ralocatable mode, 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.

Embodiment
The present invention is described with reference to the accompanying drawings.
The mounting structure of powder metallurgy brake lining of the present invention; Comprise the big steel backing 1 of arc, leg-of-mutton little triangle holder 2 and spring clamp 4; Big steel backing 1 comprises a substrate 105 and four risers 106,106 '; Big steel backing also comprises the installation position of 6 groups of little triangle holders 2, and every group of installation position comprises spherical groove 101, guide hole 102, positioning hole 103 and 3 brake lining via holes 104 and fastener recess 107, and little triangle holder 2 comprises sphere 201, leads a post 202, locating column 203 and brake lining rounded channels 204.
Brake lining mounting structure of the present invention in use; Earlier little triangle holder 2 is installed on the big steel backing 1; The post 202 of leading of little triangle holder 2 is inserted respectively in the guide hole 102 and positioning hole 103 of big steel backing 1 with locating column 203, and the sphere 201 of little triangle holder 2 is fitted with the spherical groove of big steel backing 1 101.Again brake lining 3 is contained in the little triangle holder 2, makes the fastening connection piece 31 of brake lining 3 pass the brake lining rounded channels 204 of little triangle holder 2 and the brake lining via hole 104 of big steel backing 1, utilize spring clamp 4 that brake lining 3 is fastening.Like this, after 3 brake linings were installed in the little triangle holder 2,3 spring clampes 4 fastening the time, also were fixed on 3 brake linings 3 on the big steel backing 1 with this triangle holder 2.So can accomplish installing and fixing of 6 groups little triangle holders and brake lining.
Powder metallurgy brake lining mounting structure of the present invention is a kind of ralocatable mode; Through the sphere of brake lining steel backing and the sphere of little triangle holder; 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.
