Description
Technical field
This utility model relates to a kind of servant brake, a kind of two-way slave lock.
Background technology
In prior art, Chinese utility model patent (patent No. 89219913.X) discloses a kind of bicycle brake, in
State's utility model patent (patent No. 200520077029.6) discloses a kind of front braking servo brake of electric bicycle, and China is practical
New patent (patent No. 200720035491.9) discloses a kind of servant brake for electric motor cycle, and China's utility model is special
Profit (patent No. 200910197511.6) discloses a kind of moped follow-up brake, the Chinese utility model patent (patent No.
201010112514.8) disclose a kind of moped follow-up brake.Servant brake disclosed in above-mentioned prior art, its basic structure is:
Servant brake is by fuse-box, hoof block group (comprising major and minor brake block), connecting shaft, two back-moving springs, hoof block apparatus for adjusting position, partially
Cardiac prominence wheel shaft, crank throw are constituted.Major and minor brake block is flexibly connected with fuse-box by connecting shaft, and the fuse-box servo-actuated hole herein is waist
, there is the servo-actuated interval of brake block in shape hole.Crank throw connects eccentric cam shaft, and the other end of secondary brake block is arranged on fuse-box fixing
On eccentric cam shaft centring ring cylindrical, eccentric cam shaft end is provided with eccentric cam, and eccentric cam is resisted against the another of main brake block
One end.
Existing servant brake operating principle: rotate crank throw, crank throw drives eccentric cam shaft to rotate.Eccentric cam drives main brake
Block moves, and main brake block contact brake hub produces brake force, and along with being rotated further of eccentric cam, main brake block passes through connecting shaft
Driving secondary brake block motion, major and minor brake block the most all contacts brake hub and produces brake force.Unclamping crank throw, eccentric cam can return
Turning and reset, major and minor brake block resets under two action of reset spring therewith.
The advantage of existing servant brake: due to connecting shaft can in mounting hole movable, secondary brake block and major-minor braking
Block Impact direction is the same is all neck hoof, and the direction that neck hoof produces frictional force when braking is identical with the direction of cam actuated power, because of
And make brake-shoe and brake hub paste tighter, there is self-servo action.The other end of secondary brake block is arranged on fuse-box fixing inclined
On cardiac prominence wheel shaft centring ring cylindrical, it it is the support shaft of servo brake shoe block group herein.Because this support shaft is integrally fixed on fuse-box,
So the counteracting force producing frictional force during braking all acts on fuse-box.So the advantage of servant brake is light for operation, braking
Effective.
But above-mentioned servant brake, main brake block end is by the motivator of eccentric cam, and connecting shaft is passed through in secondary brake block one end
Being connected with main brake block, the other end of secondary brake block is fixed on fuse-box on fixing eccentric cam shaft centring ring cylindrical, and not
By the motivator of eccentric cam, cause existing servant brake forward braking effect plugging weak effect very well.Servant brake is braked
Time, main brake block first contacts brake hub and contacts brake hub after secondary brake block, and during braking, stationarity is bad.
Utility model content
Technical problem to be solved in the utility model, is the defect overcoming prior art to exist, it is proposed that Yi Zhongshuan
To servant brake, can effectively solve the plugging weak effect that brakes, the phenomenon that during braking, stationarity is bad.
This utility model solves technical problem and realizes the basic ideas of utility model purpose:
Solving the plugging weak effect that brakes, cam also to drive secondary brake block, simultaneously drives major and minor brake block, makes
Drive major and minor brake block to open simultaneously, reset simultaneously.
The connecting shaft of servant brake can be movable in mounting hole, and secondary brake block is the same with major-minor brake block Impact direction
Being all neck hoof, the direction that neck hoof produces frictional force when braking is identical with the direction of cam actuated power, thus makes brake-shoe and system
Dynamic hub pastes tighter, has self-servo action.
Based on above-mentioned thinking, this utility model is to realize the two-way slave lock that utility model purpose proposes, the skill used
