Abstract
The utility model discloses a bimetallic front-axle brake drum which comprises a brake drum body and a nodular cast iron outer lining ring sleeved on the end of the brake drum body, wherein the nodular cast iron outer lining ring is also the special part of the brake drum. The bimetallic front-axle brake drum is advantageous in that due to the arrangement of sleeving the nodular cast iron outer lining ring on the brake drum body, the strength of the brake drum end face is enhanced such that the end face of the brake drum is not easy to crack even in situations of weather changes or bad road conditions, and thus the service life of a brake drum can be prolonged to six months.
Description
Technical field
The utility model relates to a kind of brake drum, the bimetal propons brake drum that particularly a kind of heavy vehicle uses.
Background technique
Brake drum is the part of drum brakes system, and during brake, piston is exerted pressure to two pairs of semi-moon shaped brake shoes, makes it be close to the tympanum inwall, thereby produces the rotation that friction stops wheel.Usually brake drum is cast as integrative-structure by gray cast iron, and in use low because of its intensity, road condition change can cause brake drum to begin cracking from end face, and use just needed to change in 3～4 months.
Summary of the invention
The technical problem that the utility model will solve provides a kind of bimetal propons brake drum of not easy to crack, long service life.
A kind of bimetal propons brake drum comprises the brake drum body, and its special way is: be socketed with lining ring outside the spheroidal graphite cast iron in the port of said brake drum body.
Above-mentioned bimetal propons brake drum, the lining ring position is provided with ladder outside the corresponding spheroidal graphite cast iron on described port, and described spheroidal graphite cast iron outer lining snare is contained on the ladder.
The utility model has the advantages that: through being socketed with lining ring outside the spheroidal graphite cast iron in brake drum body port, improve the intensity of brake drum end face, make it not easy to crack under the bad situation of changes of weather, road conditions, can extend to 6 months working life.
