Abstract
The utility model relates to a steel back structure of a high-speed train powder metallurgical brake pad, which comprises a steel plate part with a concave middle part and a T-shaped connection part. The steel plate part and the T-shaped connection part of the steel back structure provided by the utility model can be manufactured respectively through stamping and common heading methods; and during pressure sintering, the steel plate part and the connection part are assembled together and directly combined with a frication body, and no other procedure is needed. The steel back structure has the advantages of simplicity of manufacturing and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of high speed train powder metallurgy brake lining steel backing structure, belongs to the powder metallurgy friction material 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 made from 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 made as depicted in figs. 1 and 2, is made up of friction piece 1 and steel backing 2, is assembled on the brake plate support, refills to be fitted in the braking system.Steel backing 2 comprises plane steel plate part 3 and elongate cylinder attachment portion 4.Steel plate part 3 in the pressure sintering process of brake lining with friction piece 1 strong bonded together, friction piece 1 can not come off in braking process.Attachment portion 4 is fixed on the brake plate support by clamp.Must there be high adhesive strength attachment portion 4 with steel plate part 3, guarantees that the friction piece 1 that combines with steel plate part 3 is fixed on the brake plate support reliably.
The steel plate part 3 of the steel backing 2 of prior art and attachment portion 4 can be to process respectively, link into an integrated entity by welding or riveted joint again; Also can be to be cast as integrative-structure.Attachment portion 4 and steel plate part 3 joints cracking or disconnection also can appear in the steel backing 2 manufacture cost height that these modes are made, and cause the accident.
Summary of the invention
The utility model provides a kind of steel backing structure of novel powder metallurgy brake lining, is used to overcome above deficiency.
Steel backing structure of the present utility model comprises umbilicate steel plate part and T-shaped attachment portion.
This steel backing structure of the present utility model can be made by the usual way of punching press and heading respectively, when pressure sintering, the two is combined directly combines with friction piece, does not need to pass through other operation again.Therefore, it is simple that steel backing of the present utility model has manufacturing, advantage of low manufacturing cost.
Description of drawings
Fig. 1 is a prior art powder metallurgy brake lining structure;
Fig. 2 is the steel backing structure of prior art powder metallurgy brake lining;
Fig. 3 is a steel backing structure of the present utility model;
Fig. 4 is the steel plate part of the utility model steel backing;
Fig. 5 is the attachment portion of the utility model steel backing.
Embodiment
The utility model is described with reference to the accompanying drawings.
Fig. 2 is the steel backing structure of bullet train brake lining of the present utility model.Steel backing of the present utility model comprises umbilicate steel plate part 6 (see figure 4)s and T-shaped attachment portion 7 (see figure 5)s.The elongate cylinder 9 of T-shaped attachment portion 7 can be passed from the center hole 8 of steel plate part 6.The bottom surface 11 of the head of attachment portion 7 is spherical, and is consistent with the central spherical concave surface 10 of steel plate part 6.After steel plate part 6 was inserted in attachment portion 7, the end face of attachment portion 7 was concordant with the end face of steel plate part 6.
In pressure sintering process, friction material will be in the same place with attachment portion 7 and steel plate part 6 sintering, and attachment portion 7 and steel plate part 6 also can combine by effects such as diffusions.Constitute a brake lining integral body thus.
This steel backing structure of the present utility model, steel plate part 6 can be by the impact style manufacturing, and attachment portion 7 can be made by the usual way of heading, when pressure sintering, the two is combined directly combines with friction piece, does not need to pass through other operation again.Therefore, it is simple that steel backing of the present utility model has manufacturing, advantage of low manufacturing cost.
Claims (2)
1. the steel backing of a high speed train powder metallurgy brake lining is characterized in that steel backing comprises umbilicate steel plate part (6) and T-shaped attachment portion (7).
2. steel backing according to claim 1, the elongate cylinder (9) that it is characterized in that T-shaped attachment portion (7) can be passed from the center hole (8) of steel plate part (6), the bottom surface (11) of the head of attachment portion (7) is spherical, consistent with the central spherical concave surface (10) of steel plate part (6), after attachment portion (7) inserted steel plate part (6), the end face of attachment portion (7) was concordant with the end face of steel plate part (6).
