Abstract
The utility model relates to a braking device for bicycles, which is used when speed reduction or emergency braking is required in general. The utility model mainly achieves the purpose of braking via the methods such as friction, etc. When the speed of a bicycle needs to be increased after braking, force is needed to accelerate, which not only abrades mechanisms such as a steel ring, etc., but also consumes physical strength. Therefore, the utility model designs a new energy storing braking device which is composed of a wind spring disc, a spring sliding disc, a clutch sliding disc, a ratchet wheel, etc. The utility model has the functions of speed reduction, energy storage, emergency braking, etc. The utility model which has the advantages of simple structure and convenient installation does not influence the bicycle frame of the original bicycle.
Description
The utility model belongs to a kind of brake gear of bicycle.
The brake gear of bicycle slows down or uses during emergency braking at needs usually, and it mainly utilizes friction lining to be adjacent to the friction force that produces behind the movable parts to come brake bicycle.Therefore between friction lining and movable parts surface violent friction is arranged, this friction easily abrades parts surface, causes failsafety such as steel ring or main shaft to lose efficacy, and the speed of a motor vehicle after the brake needs firmly acceleration will return to speed before the brake time, consumes one's strength.
The purpose of this utility model is the bicycle brake device that stores and release energy of a kind of novelty of design.
Being characterized in installing on main shaft can be along the axially movable clockwork spring dish of main shaft, slip cap, clutch slider disc and spring slider disc, in the clockwork spring dish, clockwork spring is arranged, in clutch slider disc and spring slider disc inner chamber spring is arranged, during brake, the clutch slider disc contacts with the spring slider disc, clockwork spring tightens, energy storage, behind the releasing of brake, clockwork spring releases energy, rotate by ratchet and ratchet wheels, to save muscle power.
The utility model has the advantages that and to save physical demands.Brake is finished by two friction linings, has changed the sort of in the past mode of utilizing rubber bar friction braking on steel ring, and steel ring is difficult for scratch.
Fig. 1 is a constructional drawing of the present utility model.
As shown in the figure, this brake mainly is made up of main shaft 16, clockwork spring dish 17, spline 21, spring slider disc 8, shell 2 etc.A plurality of splines 21 are arranged on the main shaft 16.The clockwork spring dish 17 that side is equipped with clutch gear 22 can slide on main shaft 16, the interior circle of the cylindrical of clockwork spring dish 17 and ratchet 1 is connected with the outer end of clockwork spring 18, side has brake strip 4, the inner ring of clutch slider disc 13 is equipped with ratchet 12, link to each other by the cylindrical of ratchet 19 with slip cap 6, cylindrical is connected with the inner of clockwork spring 18, side has clutch friction plate 25, the slip cap 6 that endoporus has spline can slide on main shaft 16 under the effect of spring 15, its side is equipped with the clutch gear 24 that can be meshed with the clutch gear 22 on the clockwork spring dish 17, the cylindrical of shell 2 is equipped with tire steel wire 10, ratchet 3 is equipped with in the inboard, medial surface has brake strip 5, and the spring clutch 8 in its groove can slide under the effect of spring 9 vertically, is subjected to the spacing of spacing ring 14 simultaneously.Brake fork 27 links with the fixed mount 23 that is fixed on the main shaft 16 by a Xiao Ding, and the one end connects the silk 28 of stopping, and the other end contacts with clockwork spring dish 17.
During deceleration, pull the brake spanner, take out tight by brake fixed mount 23 silk 28 of will stopping, brake fork 27 is clockwise rotated, brake fork 27 promotes clockwork spring dish 17, slip cap 6 and clutch slider disc 13 move to right, the clutch gear 22 of clockwork spring dish 17 and 24 engagements of the clutch gear of slip cap 6, the friction lining 25 of clutch slider disc 13 and 26 engagements of the friction lining of spring clutch 8, clockwork spring is gradually tight, the speed of a motor vehicle slows down, the releasing of brake spanner, clutch slider disc 13 and slip cap 6 slide left under the effect of spring 15, and clockwork spring dish 17 is slippage left under the effect of spring 20, and its clutch gear 22 breaks away from clutch gear 24, the clockwork spring energy that discharges is by ratchet 1, ratchet 3 passes to shell 2, and the speed of a motor vehicle is gone up.During emergency braking, the spanner that will brake is pulled end position, makes brake strip 4 and 5 engagements of the brake strip on the shell 2 on the clockwork spring dish 17, reaches the braking purpose.Being installed in bearings 7 in the slip cap 6 among the figure, to play support spring 15,11 be fastener on the bicycle.
Claims (3)
1, a kind of bicycle dual-function braking device, form by brake silk 28, fork 27, friction lining 25,26 etc., it is characterized in that being equipped with on main shaft 16 can axially movable clockwork spring dish 17, clutch slider disc 13, slip cap 16 and spring slider disc 8, clockwork spring 18 is arranged in clockwork spring dish 17, there is ratchet 3 its outside, respectively carries the contact disk 25 and the friction lining 26 that can cooperatively interact on clutch slider disc 13 and spring slider disc 8.
2, device according to claim 1 is characterized in that at the inside face of clutch slider disc 13 ratchet 12 being arranged, and at the outside face of slip cap 6 ratchet 19 is arranged, and at the inner chamber of spring slider disc 8 spring 9 is arranged.
