Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
A kind of heat dissipation brake piston as shown in Figure 1, 2, the piston boit formed including cold extrusion and is used for positioned at piston boit front end
Connect the nose of brake block, the disc installation that nose includes the disc linkage section 1 affixed with piston boit, connect with brake block
Section 2 and the radiating segment 3 between linkage section 1 and construction section 2, radiating segment 3 include multiple in the circle for being conducive to support force structure
Week distribution while both ends are separately connected the thermal column 31 of linkage section 1 and construction section 2, the clearance space shape between multiple thermal columns 31
At fluid passage 32.When braking work, brake block contacts that friction generates heat with wheel, and the heat is from construction section 2 to rear side
Radiating segment 3 transmit, the air that when vehicle driving is flowed from the front to the back relatively can flow through each heat dissipation by fluid passage 32
The heat on its surface is taken away on the surface of column 31.
In the present embodiment, thermal column 31 includes columned core 311 and the shell 312 positioned at 311 outside of core, shell
312, which are cylindrical in shape both ends, passes through welding respectively and is fixed in linkage section 1 and construction section 2.
In the present embodiment, core 311 has outwardly extending a plurality of in expansion in one end that shell 312 is connect with construction section 2
The radiating part 313 of the outwardly extending thin sheet form of bulk, radiating part 313 fit in the surface of construction section 2 by welding to increase
Greatly with the contact area of construction section 2, so as to which quickly heat is transmitted from construction section 2 to thermal column 31.
