Abstract
The utility model relates to a brake device without braking noise, which consists of a brake drum, a brake block, a brake band, a silencing ring and a brake force transmission mechanism, wherein the silencing ring is arranged on the brake drum, the work surface of the brake drum is designed into a slotted shape for enhancing the rigidity of the brake drum, the noise generated by a brake during the braking can be eliminated under the simultaneous effect of the silencing ring and the brake drum with the enhanced rigidity, and particularly, the screaming generated by the brake device during electric bicycle braking can be eliminated.
Description
Affiliated technical field
The utility model relates to a kind of noiselessness brake gear.
Background technology
At present, the vehicular traffic brake noise has become one of source of pollution of city noise, bicycle, the employed brake holding of Electrical Bicycle, the lock that rises do not have sound arrester, the ear-piercing birdie that is sent during brake brings worry for cyclist and roadside pedestrian, especially Electrical Bicycle, he is bigger because of himself quality, the birdie that produces during brake more allows the people be difficult to stand, and along with the increase year by year of Electrical Bicycle quantity, the noise total amount also can increase thereupon.
Summary of the invention
In order to overcome existing brake drum and the brake facing of relying on, the brake gear brake that produces friction force work between brake drum and the brake band produces big this shortcoming of noise often, the utility model provides a kind of brake gear, the noise of generation when this device can be eliminated the brake gear brake of apply the brakes drum and brake band, brake facing.
The technical scheme that its technical matters that solves the utility model adopts is: brake is made up of brake drum, brake facing, brake band, noise reduction ring, brake weight transmission mechanism, inboard and noise reduction ring of lock brake drum arranged outside that rises at brake holding brake drum driving surface, the brake drum driving surface is designed to grooved, brake band and brake facing driving surface are designed to wedge shape, the flute profile angle of same brake brake drum driving surface is identical with the key groove of brake band, brake facing, and angle can require to select between 66 ° to 150 ° according to difference.After the brake drum driving surface is designed to flute profile, strengthened the rigidity of brake drum, played antihunt action, under the combined action that strengthens brake drum rigidity and noise reduction ring, can make in the noise control 25db of brake gear generation when brake.Under 70db road noise background, be to can't hear intensity that when brake produce at the following noise of 25db, we just can claim that also it is the noiselessness brake gear.
The beneficial effects of the utility model are, can eliminate the noise that brake is produced when work, the noise that is produced in the time of particularly can eliminating the large quantities of vehicle brake of cross roads on the road, and rider and pedestrian can avoid the hardship of birdie.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a brake holding apparatus structure plan sketch
Fig. 2 is a brake holding apparatus structure section plan
Fig. 3 is the brake gear structural plan scheme drawing that rises
Fig. 4 is the brake gear structural plan cutaway view that rises
1. brake drums among the figure; 2. brake band; 3. rocking bar; 4. brake facing; 5. pull bar; 6. noise reduction ring; 7. cam.
The specific embodiment
In Fig. 1, Fig. 2, brake weight acts on pull bar (5) during brake, and pull bar (5) drives rocking bar (3), and rocking bar (3) pulling brake band (2) makes brake band produce pressure to brake drum (1), thereby produce friction force between brake band and brake drum.
In Fig. 3, Fig. 4, braking action is in pull bar (5), and pull bar (5) drives rocking bar (3), and rocking bar (3) drives cam (7) and rotates, and brake facing (4) is expanded outwardly, and brake drum (1) is produced pressure.Thereby between brake band and brake drum, produce friction force.
Among Fig. 1, Fig. 3, pull bar (5) also can be a steel rope, and it is used for transmitting brake weight, and brake weight can be the direct application force of hand or pin, also can be the power that produces with hand or foot control system hydropneumatic device.
Under the combined action that strengthens brake drum (1) rigidity and noise reduction ring (6), can make in the noise control 25db of brake gear generation when brake.
Claims (2)
1. a noiselessness brake gear is made up of brake drum, brake facing, brake band, noise reduction ring, brake weight transmission mechanism, and it is characterized in that: brake drum is provided with the noise reduction ring.
2. noiselessness brake gear according to claim 1 is characterized in that the brake drum driving surface is designed to flute profile.
