Abstract
The utility model relates to a contracting brake structure with low noise for an electric bicycle, which is characterized in that the contracting brake structure comprises a brake chamber (1), a contracting brake metal band (2), a brake shoe (7), a contracting brake connecting rod (3), a cylindrical pin (4) and a curved rod (5). One end of the contracting brake metal band (3) is hinged with one end of the contracting brake connecting rod (3) and the other end of the contracting brake metal band (2) is hinged with one end of the curved rod (5); the other end of the curved rod (5)is hinged with the contracting brake connecting rod (3); one side face of the curved rod (5) contacts with the cylindrical pin (4) and can move to-and-fro along the cylindrical pin (4); and the brake shoe (7) is arranged in the inner side face of the contracting brake metal band (2). A brake disc (6) is braked by the brake shoe (7) to stop the electric bicycle from moving forward. The contracting brake structure overcomes the disadvantage of big contracting braking noise of the brake and is durable, good in effect, low in cost, simple in structure and easy to popularize.
Description
Technical field
The utility model relates to a kind of novel brake that reduces Electrical Bicycle band-type brake brake noise.
Background technology
At present Electrical Bicycle has become the indispensable walking-replacing tool of people, universal day by day along with battery-driven car, and the thorn ear noise that its band-type brake brake produces also more and more has influence on environment and the physical and mental health around ours.Originally the simple band-type brake brake that was used for bicycle generally has been installed in Electrical Bicycle, because the quality of battery-driven car is big, speed is fast, makes band-type brake brake noise very big (can reach the 90-100 decibel).
Summary of the invention
The purpose of this utility model then is at above-mentioned the deficiencies in the prior art, and the low-noise electric bicycle band-type brake that a kind of cost is low, braking effect is good brake structure is provided.
The purpose of this utility model can realize by following measure:
A kind of new Electrical Bicycle band-type brake brake structure, it is characterized in that it includes fuse-box, brake disc, band-type brake brake steel band, brake rubber block, band-type brake brake linkage bar, pin and knee are formed, one end of band-type brake brake steel band and an end of band-type brake brake linkage bar are hinged, the other end and knee one end of band-type brake brake steel band are hinged, the other end of knee and band-type brake brake linkage bar are hinged, the lateral surface of knee contacts with pin and a side of knee can move around on pin, band-type brake brake steel band medial surface is provided with brake rubber block, brake disc is installed in the fuse-box, and band-type brake brake linkage bar is hinged in fuse-box by fixed rotating shaft.
A side of described knee contacts with the side of pin, and contacted side, the side of knee and straight pin can be an also curved surface of plane, this side can move around along the side of straight pin, one end of knee one end and band-type brake brake steel band is hinged, and the other end of knee and band-type brake brake linkage bar are hinged.
Described brake rubber block is two or three.
The utility model has changed the big shortcoming of original brake band-type brake brake noise, durable and good braking effect, and cost is low, and is simple in structure, is easy to promote.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model includes fuse-box 1, band-type brake brake steel band 2, brake rubber block 7, band-type brake brake linkage bar 3, straight pin 4 and knee more than 5 parts, one end of band-type brake brake steel band 2 and an end of band-type brake brake linkage bar 3 are hinged, the other end and knee 5 one ends of band-type brake brake steel band 2 are hinged, the other end of knee 5 and band-type brake brake linkage bar 3 are hinged, a side of knee 5 contacts with straight pin 4, band-type brake brake steel band 2 medial surfaces are provided with brake rubber block 7, brake disc 6 be installed in the fuse-box 1 and with the bearing fixing of battery-driven car trailing wheel together, thereby coming disk brake lock 6 to rotate by brake rubber block 7 stops reduction of bearing rotating speed even rotation, makes battery-driven car stop to move ahead.One end of knee 5 one ends and band-type brake brake steel band 2 is hinged, the other end of knee 5 and band-type brake brake linkage bar 3 are hinged, a side of knee 5 contacts with straight pin 4, straight pin 4 is fixed on the fuse-box 1, a side of knee 5 can prolonged straight pin 4 and moved around, realize brake rubber block on its medial surface 7 and brake disc 6 deciliter, brake rubber block 7 is two or three.Band-type brake brake linkage bar 3 is hinged in fuse-box 1 by fixed rotating shaft 8.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
