CN202441779U - Brake drum - Google Patents

Abstract

The utility model discloses a brake drum consisting of a connection part and a brake part, wherein the connection part is connected with a vehicle wheel housing; and one end of the brake part, far away from the connection part, is provided with a press fit spherulitic graphite ring at the periphery, and the press fit spherulitic graphite ring is matched with the brake part. The brake drum has the following advantages: one end of the brake part, far away from the connection part, is provided with the press fit spherulitic graphite ring at the periphery, and the press fit spherulitic graphite ring is matched with the brake part and is unlikely to crack due to excellent toughness, so that the brake drum can be protected from easily cracking and the service life is longer.

Description

Brake drum

Technical field

The utility model relates to a kind of vehicle body fittings, more specifically to the brake drum that uses on a kind of automobile.

Background technique

The brake drum that uses on the vehicle at present generally adopts the gray cast iron manufacturing, and by connecting partly and the brake portion composition, this brake drum of being processed by gray cast iron breaks easily, thereby causes brake failure to cause the generation of traffic accident.

The model utility content

The purpose of the utility model is the deficiency that overcomes existing technology, the brake drum that provide a kind of and be difficult for breaking, braking quality is good.

The purpose of the utility model realizes through following technical proposals: brake drum is made up of attachment portion and brake portion; The attachment portion is connected with the vehicle hub; Its outer rim of an end away from the attachment portion in the brake portion is provided with the pressing spheroidal graphite circle that is complementary with it, that is to say that the utility model brake drum is in the brake portion of original brake drum, to add away from its outer rim of an end of attachment portion to load onto the pressing spheroidal graphite circle that is complementary.

The utility model has the advantages that because after in the brake portion of original brake drum, installing pressing spheroidal graphite circle additional with excellent toughness away from its outer rim of an end of attachment portion; Because the protection of pressing spheroidal graphite circle is arranged; Make brake drum be difficult for breaking; It is good that braking quality keeps, thereby avoid traffic accident generation, and the working life of this brake drum is longer than general brake drum.
