Abstract
The invention relates to an eccentric cam braking safety mechanism for a braking device of an electric vehicle. The eccentric cam braking safety mechanism mainly comprises an eccentric cam 1, a main brake block sheet, a main brake block and an auxiliary brake block. The eccentric cam braking safety mechanism is characterized in that an eccentric shifting block is arranged on the eccentric cam; a guiding recess is arranged at the lower end of the eccentric shifting block; an integrally fixed sheet is connected to the main brake block; a shifting block is arranged on the sheet; a guiding block is arranged at one end of the shifting block; when the eccentric cam braking safety mechanism is used, the guiding block is arranged at the upper end of the auxiliary brake block and the lower end of the eccentric shifting block; and the guiding block is movably matched with the guiding recess. Because the guiding block is arranged at the front end of the shifting block of the sheet, the favorable stability and reliability are greatly improved when the brake block is utilized in a wheel hub, the defect that the braking effect is affected by the up and down movement of the eccentric shifting block is overcome, and the eccentric cam braking safety mechanism is very convenient to use and manufacture.
Description
Technical field
Eccentric cam in the brake gear that the present invention relates to use on bicycle, battery-driven car, the motor bike and the safety gear between the contact pin of main brake piece.
Background technology
A kind of moped follow-up brake of I disclosed ZL200910192516, this structure has increased service life by continuous expansion of eccentric gear when the wearing and tearing of drag piece, but the structure in background technology is when braking, eccentric cam 2 rotates, and is connected with one slipper 4 on the monolateral mobile shifting block 22 and is flexibly connected secondary slipper 5 stressed increases.But because monolateral mobile shifting block 22 makes the shifting block effect often because of the stressed bearing surface of jumping out of main brake piece, and lost braking function, this structure exists certain defect, and does not solve the service life of whole moped follow-up brake.
Also have a kind of disclosed ZL200620126697.8 bicycle and electric vehicle servo brake and follow-up lock valve eccentric cam shaft.This structure arranges raggle block 2 at cam 3.Raggle block 2 covers hoof piece contact pin top and prevents in the braking procedure that shoe plate is climbed to the top of cam 3.Although the improvement that this structure has can not be fited with cam during the frequent return of hoof piece upper splicing, be stuck in raggle block 2 on.It is unclear that brake gear is unclasped, and affected the normal service life of brake gear.
Summary of the invention
The present invention is mainly by eccentric cam, contact pin, and main brake piece, secondary slipper, eccentric cam are provided with screw thread, connect square, eccentric block, eccentric shifting block, and eccentric cam is integrated with the square that is threaded, eccentric block, eccentric shifting block.The present invention mainly sets up guide recess below eccentric shifting block, the rivet mounting hole that fixes with the main brake piece is set in the contact pin, and be fixed as one with rivet and slipper, an end setting of the contact pin DIP piece that contacts with eccentric shifting block, the present invention mainly sets up orienting lug at the front end of DIP piece.
The present invention arranges DIP piece front end in guide recess and the contact pin by eccentric shifting block below on the eccentric cam and orienting lug is set is complementary and is provided with the free gap, stir eccentric cam during use, the DIP piece that connects on the eccentric shifting block contact main brake piece, the time guide recess of orienting lug in eccentric shifting block lower end that makes that the main brake piece moves also begins to move simultaneously.
The present invention has increased the main brake piece greatly by such improvement, and secondary slipper is stability when the recessed all lateral wearings of hub lock.Can be because main brake piece upper splicing be subjected to eccentric shifting block extention effect power, climb up eccentric shifting block and ineffective, or eccentric block is set up raggle block and stuck main brake piece recess.The present invention is not only simple, and uses very conveniently, makes the brake gear of bicycle, battery-driven car more ripe.

The specific embodiment
A kind of eccentric cam safety mechanism for braking: be provided with screw thread 4 by eccentric cam 1, contact pin 2, main brake piece 3, secondary slipper 12, eccentric cam 1, connect square 5, eccentric block 6, eccentric shifting block 7, eccentric cam 1 and screw thread 4 connect square 5, eccentric block 6, eccentric shifting block 7 is integrated.The present invention arranges guide recess 8 in the lower end of eccentric shifting block.Fixed installation hole 9 with main brake piece 3 is set in the contact pin 2.Contact pin 2 and main brake piece 3 are fixed as one by rivet, and an end of contact pin 2 is provided with DIP piece 10, and the present invention is provided with orienting lug 11 at the front end of DIP piece 10.Orienting lug 11 is integrated with 10 contact pin 2 of DIP piece.The present invention arranges guide recess 8 movable cooperation mutually by arranging in the contact pin 2 on orienting lug 11 and the eccentric cam 1.
During use, when pulling eccentric cam 1, eccentric cam 1 rotating eccentricity shifting block 7 rotation directions are rotated and are contacted with contact pin 2 DIP pieces 10,3 rotations of main brake piece, and main brake piece 3 is connected with orienting lug 11 in the one contact pin 2 in the upper end of secondary slipper 12.Mobile in the guide recess 8 of eccentric shifting block 7 lower ends.The present invention improves servant brake greatly by such improvement, the service life of hub lock, and manufacturing cost is very low, and it is also very easy to make, and makes the brake apparatus of bicycle, battery-driven car be tending towards more ripe.
