Abstract
The invention relates to a bicycle slow brake, which is used for braking a wheel ring. The bicycle slow brake comprises a brake group and a slow brake group, wherein the brake group comprises two brake arms and two brake blocks, the two brake arms are used for shortening the space correspondingly to the wheel ring, and the two brake blocks are respectively arranged on the braking arms and are used for clamping and braking the wheel ring. The slow brake group comprises at least one magnetic assembly which forms the linkage with the brake arms, and the magnetic assembly generates gradually enhanced magnetic fields on the wheel ring in the space shortening process of the brake arm, and generates magnetic resistance force exerted on the wheel ring when the wheel ring rotates to cut the magnetic field. Thereby, the invention can firstly start the pre-brake function before the brake blocks touch the wheel ring, the stability and the safety during the brake operation can be improved, and in addition, the service life of the brake blocks can also be prolonged.
Description
Technical field
The present invention relates to the slow very device of a kind of bicycle, particularly relate to a kind of bicycle slow very device and brake shoe thereof that is used for very stopping a wheel rim.
Background technology
Consult Fig. 1, the wheel rim 1 of Regular Bicycle mainly is to be limited by a brake 2 and to stop operating.This brake 2 has and is used for relatively that this wheel rim 1 dwindles two brake arms 21 of spacing, and is installed in this brake arm 21 and towards two brake shoes 22 of this wheel rim 1.When aforementioned brake arm 21 receives an external force effect and when dwindling spacing, will contact with this wheel rim 1 friction by the aforementioned brake shoe 22 of interlock, and then reach the purpose that the evil spirit stops this wheel rim 1.
Only, when the speed of a motor vehicle is accelerated, and the brake power can cause this wheel rim 1 deadlock when too quickly; Cause easily and skid, overturn ... wait danger, therefore, for the knight of specialty, can be by control brake power; Slow down the speed of a motor vehicle gradually, and keep handlingly, and then reduce dangerous generation probability; Yet the knight of specialty is a minority after all, for vast consuming public; The brake power is a kind of accumulation of empirical value and reaction when participating in the cintest, is not that everybody can control freely, and the doubt of safety aspect is arranged.
Summary of the invention
The objective of the invention is is providing a kind of bicycle slow very device and brake shoe thereof with preparatory evil spirit's function.
The slow very device of bicycle of the present invention is to be used for very stopping a wheel rim, comprises a brake group, and a slow very group.This brake group has and is used for relatively that this wheel rim dwindles two brake arms of spacing, and is separately positioned on this brake arm and towards two brake shoes of this wheel rim, aforementioned brake shoe is after aforementioned brake arm dwindles spacing, and rubbing with this wheel rim contacts.Should slow very group have at least one magnet assembly that forms interlock with aforementioned brake arm; This magnet assembly is to dwindle in the process of spacing the magnetic field that this wheel rim is produced crescendo at aforementioned brake arm; And when this wheel rim rotates cutting magnetic field, produce a reluctance force that acts on this wheel rim.
Beneficial effect of the present invention is: can produce in advance very function by reluctance force, reduce the rotating speed of this wheel rim, and then promote stability and safety when braking action, and prolong the service life of this brake shoe.
Description of drawings
Fig. 1 is a front elevation, and the brake of Regular Bicycle is described;
Fig. 2 is a block diagram, and a preferred embodiment of slow very device of the present invention's one bicycle and brake shoe thereof is described;
Fig. 3 is a top view of this preferred embodiment; And
Fig. 4 is a front elevation of this preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated:
Consult Fig. 2, Fig. 3 and Fig. 4, the slow very preferred embodiment of device of bicycle of the present invention is to be used for very stopping a wheel rim 2.This wheel rim 2 has a wheel frame 21, and takes turns a tire 22 of frame 21 around this.This takes turns frame 21 is a kind of conductors.Be somebody's turn to do slow very device and comprised a brake group 3, and a slow evil spirit organizes 4.
This brake group 3 has two brake arms 31, and two brake shoes 32.Aforementioned brake arm 31 is the bogie frames (figure does not show) that are hubbed on these wheel rim 2 two sides respectively, and being used for relatively, this wheel rim 2 dwindles spacing.Aforementioned brake shoe 32 has a matrix 321 that links with this brake arm 31 respectively, and is installed in this matrix 321 and takes turns a block 322 of frame 21 towards this wheel rim 2.Aforementioned block 322 is respectively a kind of rubber block.
Should slow very organize 4 and have four magnet assemblies 41 in this preferred embodiment.Aforementioned magnet assembly 41 is respectively a permanent-magnet material, is two two and is one group and is installed in this matrix 321, and be arranged in these block 322 2 sides and towards the wheel frame 21 of this wheel rim 2, and have two relative and opposite magnetic poles respectively.What deserves to be mentioned is that the thickness that direction is very stopped in block 332 edges of this brake shoe 33 is greater than this magnet assembly 41.
The aforementioned aforementioned magnet assembly 41 that lays respectively at these wheel rim 2 two sides can set up a magnetic field, at this moment to each other; Because aforementioned brake arm 31 is the states that are positioned at away from this wheel rim 2, the distance that aforementioned magnet assembly is 41 is far away, therefore; Magnetic field a little less than, can the rotating speed of this wheel rim 2 not exerted an influence yet.
Dwindle relatively in the process of spacing at aforementioned brake arm 31; Except meeting produces the magnetic field of crescendo because of aforementioned magnet assembly 41 hypotelorisms, the wheel frame 21 of rotation also can cutting magnetic field, produces and acts on the reluctance force that this takes turns frame 21; And along with velocity of rotation is faster; Reluctance force is stronger, and can form a preparatory very power to this wheel rim 2, and reduces the rotating speed of this wheel rim 2.
Whereby; Before this wheel rim 2 of evil spirit can not be pressed from both sides in the present invention at the block 322 of aforementioned brake shoe 32, have preparatory evil spirit's function, and can be after aforementioned brake arm 31 dwindles spacing relatively; Block 322 with aforementioned brake shoe 32 contacts with these wheel rim 2 frictions, and stable evil spirit stops this wheel rim 2.
Can know that according to the above slow very device of bicycle of the present invention and brake shoe thereof have advantage and effect:
The present invention can start in advance very function, the abrasion speed that not only can slow down aforementioned brake shoe 32 blocks 322 earlier by reluctance force before this brake shoe does not contact this wheel rim 2; Increase the service life; And importantly, no matter when being the very fast or emergency situations of general rotating speed or descending rotating speed, aforementioned preparatory evil spirit's function all can start automatically; And then can reduce the rotating speed of this wheel rim 2, stability and safety when promoting the brake action.
