Abstract
The utility model relates to auto parts, in particular to a brake drum, e.g. a steel hoop brake drum, with the view of solving the problem that the prior brake drums, cast-iron brake drums in particular, are vulnerable to crack. The steel loop brake drum is characterized in that a steel loop is fixedly sleeved on the waist loop part of the brake drum in an interference-fit manner. In the utility model, the steel loop, built in a reasonable material, is sleeved on the steel loop part of the brake drum on a reasonable interference-fit basis, so that a prestress created by the steel loop fit firmto the brake drum not only improves the strength of the waist loop part, but also, in conjunction with the pressure stress applied in anticipation to the brake drum by the interference fit, improvesthe capability of the whole brake drum in resisting a pull.
Description
Technical field
The utility model relates to auto parts machinery, and particularly brake drum is specially a kind of stirrup brake drum.
Background technique
Existing brake drum mostly is a cast iron quality, often occurs the brake drum cracking when complicated in overload of vehicle, road conditions, not only causes the maintenance expenses increase but also influences vehicle safe driving.Main cause is the cast iron quality insufficient strength, high strength material brake drum is also arranged, but expense is bigger.
Summary of the invention
The utility model provides a kind of stirrup brake drum in order to solve the particularly problem of the easy cracking of brake drum of cast iron quality of existing brake drum.
The utility model is to adopt following technological scheme to realize: the stirrup brake drum, interference fit is overlapped intrinsic stirrup at the waist hoop position of brake drum.During concrete enforcement, described stirrup can be made with seamless steel pipe (or other steel).Because during the brake drum cracking, the stressed maximum of brake drum waist hoop portion, the utility model adopts seamless steel pipe (or other steel) to be fixed in brake drum waist hoop place by interference fit, not only improved the intensity at waist hoop position but also because interference fit to brake drum pressure stress in advance, has improved the pulling force that is subjected to of whole brake drum.
Stirrup brake drum described in the utility model has been set up stirrup at brake drum waist hoop position, select reasonable stirrup material, and definite reasonable interference fit value, be loaded on brake drum stirrup position by heating resistance collar, make stirrup firmly be assemblied on the brake drum and form certain prestressing force, not only improved the intensity at waist hoop position but also because interference fit to brake drum pressure stress in advance, has improved the pulling force that is subjected to of whole brake drum.

Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the sectional view of Fig. 1;
Fig. 4 is the structural representation of existing brake drum;
Embodiment
The stirrup brake drum, interference fit is overlapped intrinsic stirrup 1 at the waist hoop position of brake drum.During concrete enforcement, described stirrup 1 usefulness seamless steel pipe (or other steel) is made.During concrete suit, need to stirrup (seamless steel pipe) heating, to satisfy the needs of interference fit.
Claims (2)
1, a kind of stirrup brake drum is characterized by: interference fit is overlapped intrinsic stirrup (1) at the waist hoop position of brake drum.
2, stirrup brake drum as claimed in claim 1 is characterized by: it is characterized by: stirrup (1) is made with seamless steel pipe.
