Cooling device for hydraulic braking systems

Abstract

A cooling device for hydraulic braking systems includes a case, a turbine unit, and a ring which is connected to an end of a hub. The case has a thorough hole and a ventilation exit communicating inside and outside of the case is defined on the case. The turbine unit is located in the case and has a fixing hole which communicates with the through hole. The ring is connected to the fixing hole of the turbine unit. The ring drives the turbine unit which generates air flows in the case. The air flows flow to the outside of the case via the ventilation exit to remove the heat of the braking system.

1 . A cooling device for hydraulic braking systems comprising:
 a case having a thorough hole defined therethrough and a ventilation exit defined on the case, the ventilation exit communicating inside and outside of the case;   a turbine unit located in the case and having a fixing hole, the fixing hole communicated with the through hole and having a plurality of protrusions at an inside of the fixing hole; and   a ring connected to an end of a hub and connected to the fixing hole of the turbine unit, the ring having a plurality of notches to engage with the protrusions;   wherein the ring drives the turbine unit which generates air flows in the case, the air flows flowing to the outside of the case via the ventilation exit to remove the heat.   
     
     
         2 . The cooling device for hydraulic braking systems as claimed in  claim 1 , wherein a guide groove is defined in a side of the turbine unit and a plurality of ribs are located around the guide groove, the ribs extended inclinedly along a curvature and toward the fixing hole, an aperture defined between any of the adjacent ribs and located on a periphery of the guide groove. 
     
     
         3 . The cooling device for hydraulic braking systems as claimed in  claim 1 , wherein a diameter of the turbine unit is larger than a diameter of the through hole. 
     
     
         4 . The cooling device as claimed in  claim 1 , wherein the turbine unit has a plurality of clamping plates located around the fixing hole and the clamping plates are arranged in pairs and located on two sides of the portions between two notches for clamping.
