Abstract
Disclosed is a servo-actuated brake device which is composed of a left hoof block, a right hoof block, an extension spring and a connection end, wherein the left hoof block and the right hoof block are formed via the connecting of the connection end, two ends of the left hoof block and the right hoof block are respectively pulled via employing two extension springs, a brake bearing surface is arranged on one end of the left hoof block, one end of the right hoof block is fixed on a boss of a wheel via an eccentric shaft, the eccentric shaft is composed of an eccentric block, a fixing pillar and a locking bolt, and a non-slipping block is arranged on an upper surface of a brake extrusion surface of the eccentric block. The utility model has the advantages of simple structure, convenient erection and utilization and the like, especially under emergency states, the utility model is capable of skidding the boss of the wheel quickly without producing any sound, thereby enabling the service time of the utility model to be increased substantially.
Description
Technical field:
The utility model relates to a kind of wheel hub brake gear of Electrical Bicycle.
Technical background: along with improving constantly of people's living standard, Electrical Bicycle is more and more accepted by numerous citizen.It is light, safe, quick that Electrical Bicycle has, lot of advantages such as energy savings.But Electrical Bicycle is running under the emergency state, usually can find relatively difficulty of brake, and follow brake, and wheel nave also can send ear-piercing brake sound.On the one hand, use so old-fashioned brake gear, under the generation emergency situation, can not effectively wheel be checked, on the other hand, the birdie of brake seriously causes environmental pollution, the service life of also having reduced Electrical Bicycle significantly simultaneously.
Summary of the invention:
The purpose of this utility model will provide a kind of servo-actuated brake gear exactly, and it can overcome the defective of above old-fashioned wheel hub of electric bicycle brake gear effectively.The purpose of this utility model is to realize like this, a kind of servo-actuated brake gear is made up of left hoof piece, right hoof piece, extension spring, coupling end, it is characterized in that: described left hoof piece and right hoof piece are to be formed by connecting by coupling end, two-end-point at left hoof piece, right hoof piece adopts two extension springs to hold respectively, end at left hoof piece is provided with the brake bearing surface, and an end of right hoof piece is fixed on the wheel hub of wheel by eccentric shaft; Described eccentric shaft is made up of eccentric block, fixed leg, lock bolt, is provided with nonslipping spur in the upper surface of described eccentric block brake compressive plane.The utlity model has characteristics such as simple in structure, easy to install, particularly running under the emergency state, can check wheel nave rapidly, and not produce any sound, make to have obtained its service life significantly improving.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of the utility model eccentric shaft;
1. right hoof piece, 2. left hoof piece, 3. coupling end, 4. extension spring, 5. brake bearing surface, 6. eccentric block, 7. nonslipping spur, 8. fixed leg, 9. lock bolt, 10. compressive plane.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing;
In the drawings, a kind of servo-actuated brake gear of the utility model is made up of left hoof piece 2, right hoof piece 1, extension spring 4, coupling end 3, it is characterized in that: described left hoof piece 2 and right hoof piece 1 are to be formed by connecting by coupling end 3, two-end-point at left hoof piece 2, right hoof piece 1 adopts two extension springs to hold 4 respectively, end at left hoof piece 2 is provided with brake bearing surface 5, and an end of right hoof piece 1 is fixed on the wheel hub of wheel by eccentric shaft; Described eccentric shaft is made up of eccentric block 6, fixed leg 8, lock bolt 9, is provided with nonslipping spur 7 in the upper surface of described eccentric block 6 brake compressive planes 10.During concrete enforcement, when Electrical Bicycle runs into the emergency state, the pulling brake gear, brake cable is attached on the lock bolt of eccentric shaft, when pulling brake wire harness, fixed leg drives the compressive plane rotation that is provided with on the eccentric build, compressive plane contacts with the brake bearing surface, the extruding bearing surface, the effect that makes left hoof piece overcome extension spring expands outwardly, contact with wheel nave, friction, thus wheel is stopped operating, and the nonslipping spur that is provided with in the upper end of the brake compressive plane of eccentric block, its objective is in brake process, left side hoof piece can not be extruded outside the track that detaches extruding in the crumpling process of eccentric block, makes the brake bearing surface of left hoof piece be in the extruding of eccentric block all the time, thereby guaranteed the safety of brake gear, after precarious position is removed, a left side, right hoof piece relies on the effect of extension spring, automatically restores to original mode of operation.The utility model adopts eccentric block to control moving of left and right hoof piece, have safe in utilization, convenient, do not produce characteristics such as any noise, and nonslipping spur is set on eccentric block, can prevent skidding off of left hoof piece effectively, when braking to reduce, the danger incessantly of stopping takes place.
