Abstract
The utility model relates to a composite brake pad, which comprises a steel back, wherein a friction material layer covers the front of the steel back. The friction material layer comprises a hard wearing layer and a heat dissipation layer; the heat dissipation layer covers the steel back; and the hard wearing layer covers the heat dissipation layer. The composite brake pad has the characteristics of reliable structure, reasonable design and good heat dissipation. The adhesive force and the bond area of the friction material layer can be increased through back holes and grooves arranged in the steel back, a metal base plate in a damping silencing sheet can damp and dissipate heat. Friction plates select multi-component composition of materials such as ceramic fiber, aluminum silicate fiber, red copper fiber and the like, and the friction plates have the characteristics of wear resistance and high temperature resistance. The brake pad overcomes the defects of the current brake pad and has a good promotional value.
Description
Technical field
The utility model relates to a kind of braking device, especially relates to a kind of composite brake sheet.
Background technique
Brake block generally is made of steel plate, thermal-protective coating, brake pad, pushes brake block to brake disc by hydraulic mechanism during brake, plays the effect of slowing-down brake by friction, and brake block also has the effect of damping and sound-absorbing simultaneously.When the unreasonable meeting of the insulating layer structure of brake block causes heat-insulating capability poor, if can not in time dispel the heat during frequently braking, heat can be delivered to hydraulic mechanism by brake block, causes the hydraulic oil vaporization, may cause braking effect variation or malfunctioning, cause accident to occur.
Summary of the invention
The purpose of this utility model is to provide a kind of composite brake sheet, and existing brake block structure is unreasonable, effect of heat insulation is poor to improve, have the technical problem such as potential safety hazard.
The utility model mainly solves the problems of the technologies described above by following technical proposals: a kind of composite brake sheet, comprise steel backing, described steel backing front is coated with friction material layer, this friction material layer comprises wearing layer and heat dissipating layer, wherein heat dissipating layer covers on steel backing, and wearing layer covers on heat dissipating layer.
As preferably, offer two dorsal pores on described steel backing, the one side that steel backing contacts with friction material layer is provided with the groove of array distribution.
The utlity model has reliable in structure, reasonable in design, the good characteristics of dispelling the heat, the dorsal pore that arranges on steel backing and groove can improve adhesion and the bond area of friction material layer, the heat dissipating layer of wiping in material layer can not only dispel the heat and the energy damping, friction plate Ceramics fiber, aluminum silicate fiber, red copper fiber and other material are polynary compound, have wear-resisting, resistant to elevated temperatures characteristics.This brake block has overcome the deficiency of existing brake block, has good promotional value.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is the structural representation of steel backing;
Fig. 4 is that the A-A of steel backing is to sectional view.
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.Fig. 1 is structural representation of the present utility model, and Fig. 2 is plan view of the present utility model, and Fig. 3 is the structural representation of steel backing, and Fig. 4 is that the A-A of steel backing is to sectional view.As seen from the figure, this composite brake sheet, comprise steel backing 1, its steel backing 1 back side is provided with shock absorption sound deadening sheet 2, steel backing 1 front is coated with friction material layer 3, and friction material layer 3 comprises wearing layer 31 and heat dissipating layer 32, and wherein heat dissipating layer 32 covers on steel backing 1, wearing layer 31 covers on heat dissipating layer 32, is provided with vertical discharge launder 33 on friction material layer 3.
Offer two dorsal pores 11 on steel backing 1, steel backing 1 one side has rectangular recess 12 with array distribution, and the distribution density of this groove 12 is 2.7-7/cm
2, the notch area of each groove 12 is 2.5-9mm
2
The wearing layer 31 of friction material layer 3 is as base material with Mullite Ceramic Fibres, potassium titanate crystal whisker, aramid fibre pulp, as modifier and bulking agent, do that Bond is bonding to be formed with nano-aluminum hydroxide, barite, potassic feldspar, magnesium hydroxide, zine oxide, graphite granule, expanded graphite with nitrile butadiene rubber, cashew nut oil modified alkyd resin.Described heat dissipating layer 32 forms with material adhesives such as red copper fiber, glue spraying aluminum silicate fiber, iron oxide, chromite, phenolic resin.
This composite brake sheet is that after wearing layer 31, heat dissipating layer 32 are mixed respectively, layering laminates, and sends into after then gluing with steel backing 1 in vulcanizing press in 270 ℃, 18MPa and makes in compound 15 minutes.
At last, should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-mentioned embodiment, and many distortion can also be arranged.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment all should be thought to belong to protection domain of the present utility model.
Claims (2)
1. a composite brake sheet, comprise steel backing, and described steel backing front is coated with friction material layer, and this friction material layer comprises wearing layer and heat dissipating layer, and wherein heat dissipating layer covers on steel backing, and wearing layer covers on heat dissipating layer.
