Abstract
The utility model discloses a bicycle brake, which is composed of an axle 1, an operating device 2, a pressurizing device 3, a linkage device 4, an oil nozzle 5, an elastic body 6, a wheel hub component 7, a bearing, relevant fasteners and other parts. The bicycle brake is arranged on a front axle and a back axle. The inner part of the wheel hub is provided with a braking torque. The stress of the wheel is uniform without noise and vibration in the braking operation. Braking pressure is changed with the wheel rotation speed in the braking operation. If the wheel rotation speed is high, the braking pressure is high. If the wheel rotation speed is small, the braking pressure is small. The vehicle speed is provided with exponential decay with safety and stability. The bicycle brake is provided with a lubricating braking system and a braking element with little working abrasion and long service life. The bicycle brake has convenient installation and beautiful appearance.
Description
The utility model is a kind of bicycle brake
The employed brake of existing bicycle is various in style, but roughly be divided into band-type brake, three types of lock and backpedalling brakes rise.This three classes brake all is a local pressure when implementing brake for the wheel of motion, owing to be local pressure, the local modification and the localized wear that certainly lead to wheel, also have noise and vibration association, all totally unfavorable service life for bicycle and brake, and some brake is installed and is also made the bicycle profile too numerous and jumbled, influences attractive in appearance; The braking reliability of brake is relevant with initial installation, in use can not adjust voluntarily with the wearing and tearing in using.Though backpedalling brake does not have above-mentioned shortcoming, limited the sense of motion of sprocket wheel, promptly change one's profession forward and sail, oppositely inconvenience is used in then braking.
The utility model is a kind of new bicycle lock of design, is installed on the antero posterior axis brake activation moment in wheel nave, overcome the shortcoming of above-mentioned three class bicycle brakes, when using this novel brake to brake, wheel is stressed evenly, and brake is easy for installation, and is handsome in appearance.The design integrates brake, wheel hub, axletree, has reduced parts, helps reducing the car load manufacturing cost.
The utility model keystone configuration is seen accompanying drawing.By 1., 2. operating control, 3. pressure device, 4. clutch, 5. oil chew, 6. elastic body, 7. hub unit, 8. bearing and associated fasteners etc. are partly formed.Control handle is installed in the bicycle handle bar, carries out drag by handling control cord line control operating control.
According to assembly relation shown in the drawings, it is installed on the bicycle, each one of antero posterior axis is adjusted bearing space and is got final product.Operating control is a kind of one-way element of unidirectional rotation, can adapt to any installation site of pressure device.Pressure device is a kind of cam mechanism.Strain the control bands of operating control during use with handle, make the operating control rotation drive pressure device and apply certain pressure to clutch, clutch and wheel hub are closely as one, make the elastomeric resilient distortion by wheel inertia, evenly be affixed on the wheel hub inwall, and impose radial pressure, make wheel hub stop, thereby reach the purpose of drag.Wherein owing to the design of the utility model uniqueness, the radial pressure of elastic body tensioner wheel hub becomes with the rotating speed of wheel, and greatly then tensioner pressure is big for vehicle wheel rotational speed, and the little then tensioner of vehicle wheel rotational speed pressure is little, and is irrelevant with the pulling force size of operating control control bands.Therefore braking is reliable, and brake rear wheel rotating speed is exponential damping, steadily safety.
The utility model is a kind of lubricated brake system to be arranged, thereby wearing and tearing are little in the braking element work, long service life.
Figure of description is a kind of most preferred embodiment of the present utility model, its by 1., 2. operating control, 3. pressure device, 4. clutch, 5. oil chew, 6. elastic body, 7. hub unit, 8. bearing and associated fasteners etc. are partly formed.According to different situations the part being changed design slightly just can be contained on the antero posterior axis or hand-held design vehicle of bicycle, as mechanical bicycle, three-wheel vehicle, trail bike etc.
Claims (4)
1. a bicycle or other roadster brake, it is made up of axle (1), operating control (2), pressure device (3), clutch (4), oil nozzle (5), elastic body (6), hub unit (7), bearing (8) and fastener, it is characterized in that being installed on the elastic deformation that elastic body (6) on the axle (1) can be created in the inner brake activation moment of hub unit (7).
2. when brake according to claim 1 is characterized in that with operating control (2) enforcement brake, pressure device (3) can make clutch (4) and hub unit (7) connect airtight and be integral, thereby makes elastic body (6) produce corresponding elastic deformation by the rotation inertia force of wheel.
3. be also that according to claim 1,2 its features of described brake operating control (2) is a kind of one-way element of unidirectional rotation.
4. be also that according to claim 1,2 its features of described brake pressure device (3) is a kind of cam.
