Abstract
The utility model provides an under the prerequisite, can alleviate brake drum self weight of guaranteeing brake drum performance to realizing whole car lightweight, reducing the vehicle oil consumption, reduce the lightweight brake drum of carbon emission, the strengthening band of evenly being located on the flange face mounting hole and being located the brake lining periphery by brake lining, the flange face, the circumference that link to each other with the brake lining constitutes, evenly is equipped with the lightening hole in flange quotation circumference, lightening hole and mounting hole staggered arrangement, and two adjacent lightening hole symmetrical arrangement are in corresponding mounting hole both sides.
Description
Technical field
The utility model relates to the drum brake of vehicle, particularly a kind of lightweight brake drum.
Background technology
At present, automobile industry is all carrying out light-weight design to car load, and automotive light weight technology design has become as to be led both at home and abroad
The Automobile Enterprises wanted reduce the important development aspect of oil consumption, not only reduce carbon emission amount, and improve the usability of vehicle
Can, present industry generally believes that light-weight design is mainly started with terms of product structure design, material etc..
Automobile brake drum is the key components and parts in brake assembly, is also relative weight than a larger part, system
Dynamic drum be by braking surface, be connected with braking surface flange face, circumference is uniformly located at flange face upper installing hole with outside braking surface
The reinforcing strip in week is constituted, and this brake drum own wt weight increased complete vehicle weight, leads to the oil consumption of vehicle high, carbon emission amount
Greatly.
Content of the invention
The utility model is to solve above-mentioned technical problem, providing a kind of premise in guarantee brake drum serviceability
Under, brake drum own wt can be mitigated, thus realizing car load lightweight, reducing vehicle oil consumption, reducing the lightweight of carbon emission amount
Brake drum.
Technical solution of the present utility model is:
A kind of lightweight brake drum, the flange face by braking surface, being connected with braking surface, circumference are uniformly pacified on flange face
Dress hole and the reinforcing strip located at braking surface periphery are constituted, and it is characterized in that and is uniformly provided with lightening hole in flange surface circumference,
Described lightening hole and installing hole interlaced arrangement, and adjacent two lightening holes are arranged symmetrically in corresponding installing hole both sides.
Further, described lightening hole is bar shaped.
The beneficial effects of the utility model are:
Due to being uniformly provided with the lightening hole with installing hole interlaced arrangement in flange surface circumference, make the weight of single brake drum
Alleviate more than 0.5kg, the loss of weight amount of only multiple brake drums has just reached more than 4kg, alleviates braking taking heavy truck as a example
Drum own wt, makes tremendous contribution for realizing car load lightweight, reduces vehicle oil consumption, decrease carbon emission amount.And loss of weight
Hole decreases the installation contact area of flange face and wheel rim, brake shoes and braking surface friction, produces amount of heat, partial heat
Discharged by lightening hole, accelerate radiating rate, improve the service life of brake drum；And when installing brake drum, decrease
Wheel rim and the contact surface of brake drum flange face, improve assembly precision.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the a-a sectional view of Fig. 1；
In figure: 1- braking surface, 2- flange face, 3- installing hole, 4- reinforcing strip, 5- lightening hole.
Specific embodiment
As illustrated, a kind of lightweight brake drum, by braking surface 1, the flange face 2 that is connected with braking surface 1, circumference uniformly set
Reinforcing strip 4 in flange face 2 upper installing hole 3 with located at braking surface 1 periphery is constituted, and is uniformly provided with bar shaped in flange surface circumference
Lightening hole 5, described lightening hole 5 and installing hole 3 interlaced arrangement, and adjacent two lightening holes 5 are arranged symmetrically in corresponding installing hole 3
Both sides.
Proved by test: due to being uniformly provided with the lightening hole 5 with installing hole 3 interlaced arrangement in flange surface circumference, make
The weight saving of single brake drum more than 0.5kg, the loss of weight amount of only multiple brake drums just reaches taking heavy truck as a example
More than 4kg, alleviates brake drum own wt, makes tremendous contribution for realizing car load lightweight, reduces vehicle oil consumption, reduces
Carbon emission amount.
During braking, brake shoes is rubbed with braking surface 1, produces amount of heat, and partial heat is discharged by lightening hole 5, plus
Fast radiating rate, improves the service life of brake drum, and when installing brake drum, decreases wheel rim and brake drum flange face
2 contact surface, improves assembly precision.
These are only specific embodiment of the utility model, be not limited to the utility model, for this area
Technical staff for, the utility model can have various modifications and variations.All of the present utility model spirit and principle within,
Any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
