Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to cooling device for
hydraulic braking systems, and more particularly to a cooling
action to the hydraulic braking system by air ventilation.
[0003] 2. Description of Related Art
[0004] 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.
[0005] 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.
[0006] 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.
SUMMARY OF THE INVENTION
[0007] The main objective of the present invention is to provide a
cooling device for improving overheat of the conventional braking
systems.
[0008] 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.
[0009] 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.
[0010] A diameter of the turbine unit is larger than a diameter of
the through hole.
[0011] 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.

DETAILED DESCRIPTION OF THE INVENTION
[0018] Referring to the drawings and initially to FIGS. 1 to 3, the
cooling device for hydraulic braking systems in accordance with the
present invention comprises a case 1, a turbine unit 2 and a ring 4
that is connected to an end of a hub 3. The case 1 is a spiral case
and a thorough hole 11 is defined therethrough. A ventilation exit
12 is defined on the case 1 and communicates the inside and the
outside of the case 1, so that the air convection between the
inside and the outside of the case 1 is possible. The turbine unit
2 is located and operated in the case 1 and the turbine unit 2 has
a fixing hole 21 which communicates with the through hole 11. A
plurality of protrusions 22 is located at an inside of the fixing
hole 21 and each protrusion 22 is an oval protrusion. The
conjunction portions between the two sides of the protrusion 22 and
the fixing hole 21 are two recesses so as to be pivotably connected
with the ring 4. A guide groove 23 is defined in a side of the
turbine unit 2 which has an open end and a closed end to reinforce
the air flows. A plurality of ribs 24 is located around the guide
groove 23 and the ribs 24 extend inclinedly along a curvature and
counterclockwise toward the fixing hole 21. An aperture 25 is
defined between any of the two adjacent ribs 24 and located on the
periphery of the guide groove 23. The aperture 25 is an elongate
hole which is cooperated with the ribs 24 to generate air flows.
The diameter of the turbine unit 2 is larger than the diameter of
the through hole 11. By the arrangement, when the turbine unit 2
operates in the case 1, the turbine unit 2 does not drop off form
the case 1. The ring 4 is connected to the fixing hole 21 of the
turbine unit 2 and a plurality of notches 41 is defined in the
outer periphery of the ring 4. The protrusions 22 are engaged with
the notches 41. The ring 4 drives the turbine unit 2 which
generates air flows in the case 1. The air flows flow to the
outside of the case 1 via the ventilation exit 12 to remove
heat.
[0019] Referring to FIG. 4, the operation status comprises a
hydraulic clamper 5 and a braking disc 6. The air flows are guided
to the hydraulic clamper 5 and the braking disc 6 via the
ventilation exit 12 to cool the braking disc 6.
[0020] Referring to FIG. 5, in the second embodiment of the present
invention, wherein the turbine unit 2 has a plurality of clamping
plates 26 located around the fixing hole 21 and the clamping plates
26 are arranged in pairs and corresponding to two sides of the
portions between two notches 41 for clamping. The ring 4 is fixed
to the turbine unit 2 so that when the hub 3 is operated, the ring
4 is co-rotated and drives the turbine unit 2 which generates air
flows in the case 1. The air flows are guided to outside of the
case 1 via the ventilation exit 12 to achieve the purpose of
cooling.
[0021] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.
