Abstract
The utility model relates to a combined type brake block. The combined type brake block comprises a steel backing, a friction piece arranged on one side of the steel backing, and a damping piece arranged on the other side of the steel backing. The friction piece, the damping piece and the steel backing are bonded through fixing glue. An installation protrusion extending outward is arranged on the circumference of the steel backing, and a chip groove is arranged in the friction piece. The combined type brake block is characterized in that a notch is arranged on the damping piece, and heat emission holes are formed at the position, corresponding to the notch, of the steel backing. With the technical scheme, the combined type brake block has the advantages that heat emission effect is good, heat produced between the friction piece and a brake disc can be emitted in time, and service life of the combined type brake block is prolonged.
Description
Technical field
The utility model relates to the auto parts machinery field, particularly a kind of combined type brake block.
Background technique
Existing a kind of combined type brake block, include steel backing, be arranged on the friction piece of steel backing one side, be arranged on the vibration damping sheet of steel backing opposite side, described friction piece, vibration damping sheet and steel backing are all bonding through fixing glue, and described steel backing circumferentially is outward extended with installs projection, described friction piece is provided with groove, the abrasive dust that this groove produces when being used for brake is discharged, thereby can prevent generation of static electricity, guarantees the frictional force between friction piece and the brake disc.
But the combined type brake block of this structure is because friction piece is when rubbing with brake disc, can produce heat, and because the steel backing opposite side is coated with vibration damping sheet, further reduce the radiating effect of steel backing, thereby so that the radiating effect of brake block is poor, working life is short.
Summary of the invention
The purpose of this utility model: in order to overcome the defective of prior art, the utility model provides a kind of combined type brake block, and its good heat dissipation effect can in time with the dissipation of heat that produces between friction piece and the brake disc, prolong its working life.
The technical solution of the utility model: a kind of combined type brake block, include steel backing, be arranged on the friction piece of steel backing one side, be arranged on the vibration damping sheet of steel backing opposite side, described friction piece, vibration damping sheet and steel backing are all bonding through fixing glue, and described steel backing circumferentially is outward extended with installs projection, and described friction piece is provided with groove, it is characterized in that: described vibration damping sheet is provided with breach, and corresponding gap position is provided with radiation hole on the described steel backing.
Adopt technique scheme, the breach that arranges at vibration damping sheet and the radiation hole that corresponding gap position arranges on steel backing are so that the brake block good heat dissipation effect can in time with the dissipation of heat that produces between friction piece and the brake disc, prolong its working life.
Further setting of the present utility model: described radiation hole is provided with even number, and described radiation hole axially is symmetrical arranged along steel backing.
Adopt above-mentioned further setting, this radiation hole set-up mode, so that the brake block heat radiation is evenly, stationarity is good.
Further setting of the present utility model: described groove sectional shape includes two parallel sides, and described two parallel sides lower ends are connected with semicircle base.
Adopt above-mentioned further setting, the groove of this shape, the stress between its two side and the bottom is little, can prevent that it from producing distortion because localized stress is excessive; And this groove can conveniently be discharged abrasive dust without the dead angle, guarantees the service behaviour of brake block.
