Abstract
The utility model discloses a brake disc of a bicycle, which is provided with an annular working area combined with a brake. A area, which is enclosed by an inner ring of the working area, on the brake disc is a non-working area, the non-working area on one side of the brake disc is fixedly connected with a gear ring, a transmission gear is integrated with the brake disc, installation space for parts is reduced, and the integral bicycle is small in volume and light in weight. Power transmission between the gear ring and a generator gear can charge a storage battery during traveling of the bicycle so as to provide energy for a bicycle-mounted electrical part, and energy is saved. The gear ring can be a plastic gear ring, the gears contact with each other flexibly, and transmission noise is reduced.
Description
Technical field
The utility model relates to a kind of braking device, is specifically related to a kind of Bicycle dished brake sheet.
Background technique
The bicycle brake device that people know has the brake jig arm that is articulated symmetrically, and the brake jig arm is clamped in the bi-side of disc brake sheet cylindrical respectively.
In addition; Bicycle develops towards direction high-grade, fashion; To complete vehicle quality, processing technology etc. require increasingly high; Traditional bicycle brake device can not satisfy bicycler's demand, so the high-grade bicycle in top, market uses the disc brake apparatus that is used for locomotive originally at bicycle.This type of Bicycle dished brake device can only provide brake function at present; And the gear that driving wheel is rotated in the conventional electric bicycle drive system is fixed on the wheel rim; Gear and disc brake sheet are separately fixing; The car load volume and weight is all bigger, can not satisfy bicycle lightweight, the market demand that volume is little.
Summary of the invention
The goal of the invention of the utility model provides a kind of bicycle brake sheet, through the use of this brake block, makes bicycle structure simple, and volume is little, in light weight.
For reaching the foregoing invention purpose; The technological scheme that the utility model adopts is: a kind of Bicycle dished brake sheet; Its outer rim is the annular working district that combines with brake; On the said disc brake sheet by in this working area the ring area surrounded be nonclient area, the nonclient area of said disc brake sheet one side is fixedly connected a gear ring.
In the preceding text, gear ring constitutes concentric the fixed connection through the disc brake sheet that is fixed on the bicycle drive shaft with wheel, and this device promptly can be used for electric bicycle, also can be used for ordinary bicycle, and generally there are following two kinds of situation in its usage mode:
(1) motor of electric bicycle is installed on the fork leg of front fork or is installed in back vent one side, small gear on the motor shaft and the gear ring engagement that is arranged on the disc brake sheet, and motor drives wheel through gear transmission and turns round.
(2) gear ring on the disc brake sheet drives on the fork leg that is installed in front fork or the generator work of back vent one side during wheel, is the power devices such as illumination of bicycle.
Preferably, said gear ring is the overall structure of integrated injection molding.Thus, gear ring has certain flexibility, and adaptive ability is strong, and wear resistance is good.
Because the technique scheme utilization, the utility model compared with prior art has advantage:
1. driving gear of the utility model and disc brake sheet combine, and reduce the installing space of part, and the car load volume is little, in light weight.
2. gear ring of the utility model and the power transmission between the generator gear can be charge in batteries in bicycle is advanced process, for vehicle mounted electrical apparatus spare provides energy, and energy saving.
3. the gear ring of the utility model is connected with the disc brake sheet body-fixed, can adopt working of plastics to make gear ring thus, through engaging, be spirally connected or mode such as riveted joint is fixed on the disc brake sheet; Also can directly be injected on the disc brake sheet; Adopt the plastics gear ring, gear is flexible contact, reduces rotational noise.
Description of drawings
Fig. 1 is the utility model embodiment one a structural representation;
Fig. 2 is embodiment one a left view;
Wherein: 1, disc brake sheet; 2, vent hole; 3, insulation hole; 4, gear ring; 5, flower-drum lockhole; 6, flower-drum jack.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Embodiment one: shown in Fig. 1～2, and a kind of Bicycle dished brake sheet, a flower-drum jack 6 is offered at its center, offers 6 flower-drum lockholes 5 around the flower-drum jack, utilizes screw to be fixedly connected with flower-drum; The edge is circumferentially with a plurality of oval insulation holes 3 and triangle vent hole 2 in the working area of disc brake sheet 1.Through said structure, the ventilation and heat performance of disc brake sheet 1 is good.
The outer rim of said disc brake sheet 1 is provided with the annular working district that combines with brake, on the said disc brake sheet 1 by in this working area the ring area surrounded be nonclient area; The nonclient area inner ring of said disc brake sheet 1 one sides is fixedly connected a ring gear 4, and said gear ring 4 is between insulation hole 3 and flower-drum lockhole 5, and near insulation hole 3.Fricative high temperature damaged gear ring 4 to the inner ring transmission when disc brake sheet 1 utilized insulation hole 3 to stop its brake.
Preferably, said gear ring 4 is concentric with flower-drum jack 6, is fixed on the disc brake sheet 1, and this gear ring 4 has certain flexibility for to be processed by composite material, and adaptive ability is strong, and wear resistance is good, realizes the low noise gear engagement driving.Gear ring 4 in the present embodiment according to circumstances also can use external toothing.
In the preceding text, gear ring constitutes concentric the fixed connection through the disc brake sheet that is fixed on the bicycle drive shaft with wheel, and this device promptly can be used for electric bicycle, also can be used for ordinary bicycle, and generally there are following two kinds of situation in its usage mode:
(1) motor of electric bicycle is installed on the fork leg of front fork or is installed in back vent one side, small gear on the motor shaft and the gear ring engagement that is arranged on the disc brake sheet, and motor drives wheel through gear transmission and turns round.
(2) gear ring on the disc brake sheet drives on the fork leg that is installed in front fork or the generator work of back vent one side during wheel, is the power devices such as illumination of bicycle.
Claims (2)
1. Bicycle dished brake sheet; Which is provided with the annular working district that combines with brake; It is nonclient area that said disc brake sheet (1) is gone up by ring area surrounded in this working area, and it is characterized in that: the nonclient area of said disc brake sheet (1) one side is fixedly connected a gear ring (4).
2. Bicycle dished brake sheet according to claim 1 is characterized in that: said gear ring (4) is the overall structure of integrated injection molding.
