Abstract
A brake drum comprises an outer layer, an inner friction layer and an adhesive layer, wherein the adhesive layer is arranged between the outer layer and the inner friction layer. The brake drum is safe to use and simple in structure and is economic and adaptable.
Description
Technical field
Background technique
Brake drum is the pith of drum brakes system, and in when brake, piston is exerted pressure to two pairs of brake blocks, makes it to be close to the tympanum inwall, through between the frictional force that produces stop the rotation of wheel, reach the purpose of braking.At present, brake drum commonly used generally is made up of the wear resisting cast iron of outer field wrought cast iron and internal layer, and two-layer cast iron passes through bolt.And the wear resisting cast iron layer of brake drum internal layer only need use 5～10mm usually, but because need construction bolt, wear resisting cast iron layer need thicken 2～3cm usually; The brake drum of this structure; Not only the raw material consumption is big, and adopts the mode of bolt, bolt easily and brake drum be sticked together; Causing can't repair and replacement, has had a strong impact on traffic safety.
The model utility content
The utility model aims to provide a kind of safe in utilization, and is economic and practical, brake drum simple in structure.
The technological scheme that the utility model adopted is: a kind of brake drum, comprise outer layer body and internal friction layer, and it is characterized in that also comprising that bonding layer, bonding layer are located between outer layer body and the internal friction layer.
Said internal friction layer is divided into four, through the sticking outer layer body inside that is posted on of bonding layer.
Said bonding layer is a resin bonded laminate.
Said outer layer body is the wrought cast iron layer.
Said internal friction layer is the wear resisting cast iron layer.
The beneficial effect of the utility model is: through the fire resistant resin tackiness agent brake drum outer layer body and internal layer applying back oven dry can be used; Simple in structure, saved the operation that conventional brake rouses boring, installs bolt additional, and; Internal layer friction layer thin thickness has been saved raw material.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of brake drum of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
The embodiment of the utility model is shown in accompanying drawing, and a kind of brake drum comprises outer layer body 1, internal friction layer 2, bonding layer 3, and bonding layer 3 is located between outer layer body 1 and the internal friction layer 2, with outer layer body 1 and internal friction layer 2 good bond.In the actual production, outer layer body 1 can select for use the strong cast iron of forgeability to produce, and the cast iron that it is good that internal friction layer 2 can be selected wear-resisting property for use is produced, and bonding layer 3 adopts the fire resistant resin tackiness agent.In the actual application, internal friction layer 2 can be divided into some uniformly, and four, six or eight evenly are bonded in the inboard of outer layer body 1, thereby the brake drum that the effect of effectively having avoided expanding with heat and contract with cold is brought destroys, and has improved the performance of brake drum.
Claims (5)
1. a brake drum comprises outer layer body and inside, it is characterized in that also comprising that bonding layer, bonding layer are located between outer layer body and the internal friction layer.
2. a kind of brake drum according to claim 1 is characterized in that: said internal friction layer is divided into four, sticks on outer layer body inside through bonding layer.
3. a kind of brake drum according to claim 1 is characterized in that: said bonding layer is a resin bonded laminate.
4. a kind of brake drum according to claim 1 is characterized in that: said outer layer body is the wrought cast iron layer.
5. a kind of brake drum according to claim 1 is characterized in that: said internal friction layer is the wear resisting cast iron layer.
