- 2. Description of Related Art
- Bicycles are very popular today. When a cyclist rides a bicycle along an uphill, the braking system ensures the safety for the cyclist and the modern braking system is operated by hydraulic system which drives the lining plates in the braking system to contact the braking disc to slow down and stop the wheel. For the reason of safety, it is necessary to brake frequently when the cyclist rides along a downhill. Consequently, the braking disc can be overheat and further reduce the friction coefficient between the lining plates and the braking disc, such that the cyclist might be dangerous when the braking system is not work.
- Some manufacturers set recesses defined in the braking disc to allow air to flow through the recesses along the tangent direction to remove the heat when the braking disc rotates. However, the braking disc is a hollow plate which cannot generate air ventilation by the rotation of itself, thus the temperature cannot be reduced efficiently. When the temperature of the braking disc continuously increases, the braking function is not sensitive and the braking disc may be deformed permanently. The deformation may cause cracks to the braking disc so that it is important to reduce the high temperature of the braking disc to ensure the safety of the riders.
- The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional braking systems and provides a cooling device for hydraulic braking systems to cool down the braking disc.
- The main objective of the present invention is to provide a cooling device for improving overheat of the conventional braking systems.
- To achieve the objective, a cooling device for hydraulic braking systems comprises 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, 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.
- 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.
- A diameter of the turbine unit is larger than a diameter of the through hole.
