Description
The present invention relates to bicycle brake device technical field.
Bicycle in the past, its brake system and drive system are fully independently, the function of the two also is antipodal: driving is to supply with bicycle with energy, and braking then is to consume its energy, promptly bicycle is slowed down so that stop by the friction between brake component and the braked part.Obviously, this brake system is very big to the waste of energy, will often slow down in the crowded traffic highway section for travelling to dodge or all the more so at the bicycle of the more intersected country of uphill/downhill.
Purpose of the present invention will be created a kind of New Brake exactly, when it implements glancing impact to the bicycle in travelling, not its energy to be consumed in vain mourn, but it is stored with another kind of form, when finishing glancing impact or when needed, these energy can be converted into propulsive effort again automatically.
The present invention realizes by the following method: adopt a dish clockwork spring as accumulator, and limit turning to of the inner and barrel of clockwork spring respectively with two ratchets, when bicycle is implemented glancing impact, operating a power-transfer clutch links wheel and clockwork spring the inner and spring is tightened and bicycle slows down so that stop, and when the end of braking spring discharged, barrel rotated and drive wheels.
Also describe the present invention in conjunction with the accompanying drawings in detail below by two embodiment.
Embodiment one:
Present embodiment adopts friction clutch.
Shown in figure one, energy storage type brake is made up of closed-centre system and clutch system.Closed-centre system mainly is made up of clockwork spring 13, barrel 11, bearing and ratchet assembly set 10, ratchet 14 and drg 12 etc.Bearing and ratchet assembly set 10(can adopt the structure that is similar to bicycle freewheel, form by a ratchet and two antifriction-bearing boxs), be fixed on the axletree rod 17, the inner of clockwork spring 13 is fixed on bearing and the ratchet assembly set 10, the outer end then is fixed on the inside of barrel 11, barrel 11 two side ends are sleeved on bearing and the ratchet assembly set 10 by antifriction-bearing box 9, and barrel 11 links by ratchet 14 and wheel floral disc 15.The effect of ratchet 14 is not drive barrel 11 when wheel rotates forward, and can drive wheel when clockwork spring 13 releases are rotated barrel 11 in the same way.Drg 12 is normal lock, and normal condition is held barrel 11 tightly.Clutch system mainly is made up of baffle ring 1, change 3, slip ring 4, throw-out collar 6, push rod 8, friction disc 16, spring 7 and two antifriction-bearing boxs 2 and 5.Slip ring 4 is sleeved on the spline of axletree rod 17, can slide vertically, and contact with pitch face with change 3.Some push rods 8 pass the through hole on the rotatable part of bearing and ratchet assembly set 10, two ends respectively with throw-out collar 6 and friction disc 16 Joints.
During the bicycle cruising, ratchet 14 is carry-over moment not, and friction disc 16 is thrown off with wheel floral disc 15, and therefore, clockwork spring 13 the inners and barrel 11 all do not rotate.
Work as glancing impact, the 18 pulling changes 3 of rim brake pull bar are rotated, promoting slip ring 4 under the effect of the axial component on its inclined-plane that contacts with slip ring 4 moves vertically, slip ring 4 promotes throw-out collar 6 by antifriction-bearing box 5 again, friction disc 16 is contacted with wheel floral disc 15, and under the effect of friction force, friction disc 16 rotates the rotatable components that drives bearing and ratchet assembly set 10 with wheel floral disc 15, thereby tighten clockwork spring 13, bicycle slows down so that stop.
During end of braking, change 3 counter-rotating reset (as common brake resets under the effect of spring force).Under the effect of spring 7, friction disc 16 grades also reset.Because the effect of ratchet, can not reverse in clockwork spring 13 the inners.
When needs, release the brake 12, clockwork spring 13 discharge and make barrel 11 rotate and rotate by ratchet 14 drive wheels.
From the aforesaid operations process as can be seen, this storage drg is the time-delay drive-type, and promptly the end of braking rear spring does not discharge immediately, only could be used for driving by release spring when drg 12 unclamps.The time-delay drive-type is suitable for the more intersected country of uphill/downhill, and unnecessary energy storage is got up in the time of can be with the bicycle descending, is used further to when to be gone up a slope drive.
If adopt a link gear that change 3 and drg 12 are linked up, promptly rotate and glancing impact in change 3, drg 12 is also held barrel 11 tightly, and when end of braking change 3 resetted, drg 12 also unclamped.So, energy storage type brake then becomes instant drive-type, and promptly during end of braking, spring can discharge immediately and drive bicycle.Instant drive-type is suitable for city and region of no relief.In addition, for increasing friction force, also friction disc 16 can be changed into other pattern (as the circular cone type or the lock etc. that rises), this class variation does not exceed the present invention.
Embodiment two:
Present embodiment adopts differential clutch.
Shown in figure two, energy storage type brake for bicycle mainly is made up of a dish clockwork spring 4, two ratchets (9,11), differential gear train and two drgs (8,10).Differential gear train is made up of the tie-rod 6 and the inner gear 3 of sun wheel 5, band satellite gear 7.
The same axle mounting of energy storage type brake and wheel.Clockwork spring 4 the inners are fixed on the sun wheel hollow shaft 1, link with ratchet 11 between this axle and the axletree rod 12, and the effect of ratchet 11 is that direction that sun wheel hollow shaft 1 can only be tightened toward clockwork spring 4 is rotated and can not be reversed.Clockwork spring 4 outer ends are fixed on barrel 2 inside, link with ratchet 9 between barrel 2 and the inner gear 3, the effect of ratchet 9 is that barrel 2 can drive inner gear 3 rotations when clockwork spring 4 was discharged, and rotates and do not drive barrel 2 when inner gear 3 rotates in the same way for the active crop rotation.Tie-rod 6 links with wheel.
When the bicycle cruising, drg 8 is releasing orientation, and wheel drives tie-rod 6 and rotates, and inner gear 3 is done idle running in the same way, and sun wheel 3 is not rotated owing to the load of clockwork spring 4.
Work as glancing impact, drg 8 is held inner gear 3 tightly and is made it to stop operating, and 1 of sun wheel hollow shaft is done and wheel rotation in the same way as driven shaft, and clockwork spring 4 is tightened, the kinetic energy of bicycle and potential energy promptly are converted into the energy storage of clockwork spring 4, and bicycle slows down so that stop.
When stopping glancing impact, drg 8 unclamps, because the effect of ratchet 11, sun wheel hollow shaft 1 can not reverse and maintain static, clockwork spring 4 discharges barrel 2 is rotated along the wheel working direction, and drives inner gear 3 rotations by ratchet 9, does to rotate in the same way with wheel thereby drive tie-rod 6.
After clockwork spring 4 had discharged, bicycle was returned to the cruising state.
In the operating process of above-mentioned energy storage type brake, do not use drg 10(and promptly can cancel), this is instant drive-type.If drg 10 is placed constant locked position, then this energy storage type brake becomes the time-delay drive-type
In the present embodiment, also can be with the shaft transposing direction of the shaft of tie-rod 6 and sun wheel 5, promptly sun wheel 5 links with wheel, and fixing the inner of clockwork spring 4 on the shaft of tie-rod 6.
By theory of machines as can be known:
When inner gear 3 fixedly the time, it is identical that tie-rod 6 and sun wheel 5 turn to, and the reduction ratio of 5 pairs of tie-rods 6 of sun wheel is
i
Sun wheel. tie-rod=1+(Z
Inner gear)/(Z
Sun wheel) (＞2)
When sun wheel 5 fixedly the time, inner gear 3 is also identical with turning to of tie-rod 6, and the reduction ratio of 3 pairs of tie-rods 6 of inner gear is
i
Inner gear. tie-rod=1+(Z
Sun wheel)/(Z
Inner gear) (＜2)
When tie-rod 6 fixedly the time, it is also identical that inner gear 3 and sun wheel 5 turn to, and the reduction ratio of 3 pairs of sun wheels 5 of inner gear is
i
Inner gear. sun wheel=(Z
Sun wheel)/(Z
Inner gear) (＜1)
According to above-mentioned analysis, when the scheme that adopts tie-rod and wheel to link, clockwork spring is tightened more than two circles because of wheel turns around, bicycle can be braked rapidly in short range.This scheme is suitable for crowded traffic areas such as city.Otherwise when the scheme that adopts sun wheel and wheel to link, wheel takes two turns above, and clockwork spring just tightens a circle, and spring discharges one and encloses, and wheel then turns around above.This scheme can make bicycle obtain the spring propulsive effort in long operating range under the certain condition of spring length.Therefore, be suitable for the more intersected country of uphill/downhill.
Compare with traditional cycle brake, the present invention can be that spring can store with the kinetic energy and the potential energy converting and energy of bicycle, when finishing glancing impact or needing, can be used for again driving.Braking force propulsive effort be can be converted into automatically, thereby rider's the muscle power and the hill climbing ability of increase bicycle saved greatly.
In practicality, can adopt common rim brake operating energy storage type brake.When adopting instant drive-type, can be only to the trailing wheel braking, and keep the common brake of a cover, be used to stop and the braking when not continuing to travel.And adopt when delaying time drive-type, then needn't keep common brake, the front and back two-wheeled all can be installed energy storage type brake.At this moment, can establish handle in addition and come operational brake 10.
The present invention also can be widely used in various rickshaws except that being used for bicycle, as pedal three-wheel vehicle and car for disabled persons etc.
