Description
Technical field
The present invention relates to a kind of Disk brake apparatus.
Background technique
In general, Disk brake apparatus is configured to comprise: internal drive, and this internal drive is arranged on the running shaft regularly; Brake disc, this brake disc are arranged on this internal drive, can move on axle direction, but the motion on sense of rotation are restricted; Armature and outside hung brake dish, this armature and outside hung brake dish lay respectively at the both sides of described brake disc; And coil, when energising, this coil holds described armature, thereby makes described brake disc be in free state.In above-mentioned Disk brake apparatus, there is the problem that causes the whole heating of Disk brake apparatus because of coil heating.In order to address this problem, a kind of scheme is for example disclosed in patent documentation 1, it is provided with helical fan on running shaft, with the past vent hole that is arranged on coiler part of wind, cool off (for example with reference to patent documentation 1) with this by this fan.
Patent documentation 1 spy of Japan opens flat 10-77179 communique
But, in the disclosed technology of above-mentioned patent documentation, owing to need carry out this processing operation of perforate in the side of coiler part, so there is the loaded down with trivial details problem of operation.In addition, this technology can't be applied in the existing equipment that has been provided with.
Summary of the invention
The present invention makes in order to solve the practical problem that exists in the above-mentioned prior art, the object of the present invention is to provide a kind of operation good, and can be applied in the Disk brake apparatus in the existing equipment that has been provided with.
To achieve these goals, a first aspect of the present invention has proposed a kind of Disk brake apparatus, and this Disk brake apparatus comprises: internal drive, and this internal drive is arranged on the running shaft regularly; Brake disc, this brake disc are arranged on this internal drive, can move on axle direction, but the motion on sense of rotation are restricted; Armature and outside hung brake dish, this armature and outside hung brake dish lay respectively at the both sides of described brake disc; And coil, when energising, this coil holds described armature, thereby make described brake disc be in free state, described Disk brake apparatus is characterised in that, end at described internal drive is provided with blade, mixes ambient air by this blade, with this peripheral equipment that comprises internal drive is cooled off.
According to a first aspect of the present invention with said structure, a kind of cooling structure can be provided, because this structure just is provided with the blade that mixes surrounding atmosphere in the end of internal drive, so installation is very simple, operation is very excellent.
In addition, according to a first aspect of the invention, the Disk brake apparatus of a second aspect of the present invention is characterised in that the size of described blade is less than the diameter of described internal drive.
According to this structure, when taking break apart, do not need to pull down blade.
According to the present invention, a kind of cooling structure is provided, because this structure just is provided with the blade that mixes surrounding atmosphere in the end of internal drive, so installation is very simple, operation is very excellent.

Embodiment
Followingly describe with reference to the mode of execution of accompanying drawing to Disk brake apparatus involved in the present invention.
Fig. 1 is the side cutaway view of expression as the Disk brake apparatus of one embodiment of the invention, and Fig. 2 is the front view of Fig. 1, and Fig. 3 is the unfolded drawing of three blades, and Fig. 4 is the unfolded drawing of four blades, and Fig. 5 is the unfolded drawing of six blades.
In Fig. 1 and Fig. 2, the internal drive 2 that is arranged on regularly on the solid of rotation 1 together rotates with solid of rotation 1.By the fixing end that with screw etc. blade 3 is fixed on internal drive 2 with hole 3a.At this moment, the size of blade 3 is set for diameter less than internal drive 2.Described internal drive 2 is provided with brake disc 7, and this brake disc 7 can move at axle direction, but the motion on sense of rotation is restricted.The both sides of this brake disc 7 are provided with armature 6 and outside hung brake dish 8.Utilization is pressed into this brake disc 7 on the outside hung brake dish 8 from armature 6 sides by pressing spring 9, makes thus between brake disc 7 and the armature 6 and between brake disc 7 and the outside hung brake dish and produces frictional force, produces braking moment by this frictional force.When the release break, make coil 5 energisings and make 4 magnetization unshakable in one's determination, armature 6 is attracted towards coil sides, thereby make between brake disc 7 and the armature 6 and the disappearance of the frictional force between brake disc 7 and the outside hung brake dish 8.
When making coil 5 energisings discharge break, the heat that produces in coil 5 makes the temperature of break integral body rise.When running shaft 1, internal drive 2 and blade 3 rotations, blade 3 is cooled by rotation, and its result has not only cooled off internal drive 2, but also has cooled off running shaft 1.In addition, because the effect of mixing that produced of blade 3, make and flow in the gap of air between armature 6, outside hung brake dish 8 and brake disc 7, thereby obtain effect that break is cooled off.
In addition, when making blade 3, make the plate object shown in the unfolded drawing of Fig. 3 to Fig. 5 earlier, then dotted portion 3b bending is obtained blade, can make things convenient for thus and make blade 3 at an easy rate.In addition, in order not hinder the apportioned effort of break, the size of blade shown in Figure 23 need be set for diameter less than internal drive 2.
Claims (2)
1. Disk brake apparatus, this Disk brake apparatus comprises: internal drive, this internal drive is arranged on the running shaft regularly; Brake disc, this brake disc are arranged on this internal drive, can move on axle direction, but the motion on sense of rotation are restricted; Armature and outside hung brake dish, this armature and outside hung brake dish lay respectively at the both sides of described brake disc; And coil, in when energising, this coil holds described armature, thereby makes described brake disc be in free state, and described Disk brake apparatus is characterised in that,
End at described internal drive is provided with blade, mixes ambient air by this blade, with this peripheral equipment that comprises described internal drive is cooled off.
2. Disk brake apparatus as claimed in claim 1 is characterized in that the size of described blade is less than the diameter of described internal drive.
