Abstract
The invention discloses a servo brake. A brake box is provided with an eccentric cam shaft mounting hole and a connecting shaft servo hole. Each end of a primary braking block and a secondary braking block are hinged together through a connecting shaft; and the connecting shaft is mounted in the connecting shaft servo hole. An eccentric wheel shaft is mounted in the eccentric cam shaft mounting hole and the other end outside an eccentric wheel shaft brake box is provided with a crank throw. The end part of one end in the eccentric wheel shaft brake box is an eccentric body and the eccentric body is a flat column body; and two narrow side faces are circular-arc-shaped faces. A vertical central line of the eccentric body is deviated from an axis of an eccentric wheel shaft and is parallel to the axis of the eccentric wheel shaft; and a pre-set distance is kept. The end parts of the primary braking block and the secondary braking block respectively lean against the wide side faces of the eccentric body. According to the servo brake disclosed by the invention, when the eccentric body rotates, the eccentric body is stressed between the end parts of the two braking blocks and is dynamically stressed, so that a clamping phenomenon that a brake is not loosened after being locked is greatly reduced and the servo brake has an anti-clamping effect. With the adoption of an eccentric structure, the braking effect is ensured.
Description
Technical field
The present invention relates to a kind of bicycle, boosted vehicle, electric vehicle servant brake.
Background technology
Chinese utility model patent (patent No. 200720035491.9) discloses a kind of servant brake for electric motor cycle, and Chinese invention patent (patent No. 200910197511.6) discloses a kind of motor-car servant brake.Servant brake disclosed in two patent documents, its basic structure is identical, all have employed the basic structure that existing servant brake generally adopts.The basic structure of existing servant brake by the hoof block group in fuse-box and fuse-box (also known as major and minor slipper, or upper and lower hoof block) form, major-minor slipper is flexibly connected with fuse-box by adapter shaft, and fuse-box servo-actuated hole is herein waist shaped hole, there is the servo-actuated interval of secondary slipper.Brake rod connects adapter shaft, and the other end of secondary slipper is fixed on adapter shaft, and adapter shaft end is provided with eccentric cam, and eccentric cam is resisted against the other end of main brake block.Rolling brake bar, eccentric cam relies on eccentric action main brake block to produce braking force, and along with being rotated further of eccentric cam, main brake block drives secondary slipper servo-actuated by adapter shaft, and two hoof blocks produce braking force thereupon simultaneously.Take-off the brake bar, eccentric cam can turn round reset, and two hoof blocks reset thereupon.But, this structure, its eccentric cam is coaxial assembling with secondary slipper end, not stressed, only stressed with main brake block end, add the reason that eccentric cam shape is intrinsic, in high vehicle speeds process, when carrying out emergency braking, after braking procedure terminates, eccentric cam and main brake block end there will be stuck phenomenon, can not reset, cause brake locking.
Summary of the invention
Technical matters to be solved by this invention, is the defect overcoming prior art existence, proposes a kind of servant brake, effectively can prevent the generation of brake stuck phenomenon.
Servant brake of the present invention, comprises fuse-box, main brake block, secondary slipper, crank throw, eccentric cam shaft; Fuse-box is provided with eccentric cam shaft mounting hole and the servo-actuated hole of adapter shaft; One end of main brake block and secondary slipper is hinged by adapter shaft, and adapter shaft is arranged in the servo-actuated hole of adapter shaft; Camshaft is arranged in eccentric cam shaft mounting hole, and crank throw is installed in the one end outside camshaft fuse-box; It is characterized in that: in camshaft fuse-box, end, one end is eccentric body, described eccentric body is flat-shaped cylinder, and two narrow side is arc surface; The longitudinal centerline of eccentric body departs from camshaft axis and is parallel to each other, and keeps the spacing of setting; Establish extension spring between the other end end of main brake block and secondary slipper, the end of main brake block and secondary slipper is resisted against on the broad side surface of eccentric body respectively.
During car brakeing, pull crank throw, rotate eccentric body, eccentric body is due to eccentric structure, and eccentric body can drive the end of main brake block to move rapidly outward, first main brake block produces braking force, along with being rotated further of eccentric body, main brake block can drive secondary slipper servo-actuated by adapter shaft, and eccentric body can drive the end of secondary slipper slowly to move outward simultaneously, until two slipper all produce braking force, reach the object of brake.Unclamp crank throw, eccentric body, major-minor slipper can reset under the effect of extension spring.
The present invention, because eccentric body is flat-shaped cylinder, the force structure close to stress balance is there will not be when braking, simultaneously, because eccentric body has motivator to main brake block and secondary slipper, be in dynamic stress, therefore, do not unclamp the generation of i.e. stuck phenomenon after greatly reducing brake locking, there is anti-seize effect.Owing to adopting eccentric structure, ensure that braking effect.
So-called eccentric body is flat-shaped cylinder, refer to two slipper against position be flat-shaped cylinder.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figure 1, 2, 3, servant brake 1, comprises fuse-box 2, main brake block 12, secondary slipper 14, crank throw 10, eccentric cam shaft 8; Fuse-box is provided with eccentric cam shaft mounting hole 27 and the servo-actuated hole 24 of adapter shaft.One end of main brake block and secondary slipper is hinged by adapter shaft 5, and adapter shaft 5 is arranged in the servo-actuated hole 24 of adapter shaft.Pad 3 is sleeved on adapter shaft 5, and inside jam nut 4, jam nut 4 is sleeved on adapter shaft 5, for the axial motion of fixed connection shaft 5 on fuse-box 2.Adapter shaft 5 one end is contained on main brake block and secondary slipper, and be used for supporting main brake block and secondary slipper and rotate, one end is contained in the servo-actuated hole 24 of fuse-box adapter shaft, and when guaranteeing to brake, main brake block and secondary slipper is servo-actuated, increases braking force.Axis mounting hole 6 is used for installing brake on motor axis.
Camshaft 8 is arranged in eccentric cam shaft mounting hole 27, crank throw 10 is installed in one end outside camshaft fuse-box, crank throw jam nut 7 coordinates for locking crank throw 10 with crank throw lock screw 9, makes crank throw be fixed on eccentric cam shaft 8, and the crank throw of crank throw stops line mounting hole 11 for connecting line of stopping.In camshaft fuse-box, end, one end is eccentric body 28.As shown in Fig. 4,5,6,7,8, described eccentric body 28 is flat-shaped cylinder, and two narrow side is arc surface.The longitudinal centerline of eccentric body 28 and camshaft axis, keep the spacing of setting not point-blank and be parallel to each other.Establish extension spring (also known as slipper reset tension spring) 18 between the other end end of main brake block and secondary slipper, the end of main brake block and secondary slipper is resisted against on the broad side surface of eccentric body 28 respectively.
