Abstract
The invention discloses an eccentric camshaft for a servo brake. The eccentric camshaft for the servo brake consists of a crank throw connection part, a driving shaft and an eccentric body in sequence. The eccentric camshaft for the servo brake is characterized in that the eccentric body is a flat cylinder, two narrow side surfaces of the eccentric body are arc surfaces; the longitudinal center line of the eccentric body is parallel to the axial line of the driving shaft and a set distance is kept between the longitudinal center line and the axial line. According to the eccentric camshaft, the eccentric body is the flat cylinder, so that the eccentric body does have a structure with stress closed to be balanced during the braking; and at the same time, the eccentric body has motivation force to both a primary brake block and a secondary brake block and is dynamically stressed, so that the phenomenon of locking after brake locking without loosening is greatly reduced and the effect of preventing the locking is provided.
Description
Technical field
The present invention relates to a kind of bicycle, boosted vehicle, electric vehicle servant brake parts, is that a kind of servant brake is used eccentric cam shaft specifically.
Background technology
China's utility model patent (patent No. 200720035491.9) discloses the automobile-used servant brake of a kind of electric motorcycle, and Chinese invention patent (patent No. 200910197511.6) discloses a kind of motor-car servant brake.Two disclosed servant brakes of patent document, its basic structure is identical, the basic structure that has all adopted existing servant brake generally to adopt.The basic structure of existing servant brake (is claimed major and minor slipper again by the hoof piece group in fuse-box and the fuse-box; Or upper and lower hoof piece) constitutes; The major-minor slipper flexibly connects through adapter shaft and fuse-box, and fuse-box servo-actuated hole herein is a waist shaped hole, exists secondary slipper servo-actuated interval.Brake rod connects adapter shaft, and the other end of secondary slipper is fixed on the adapter shaft, and the adapter shaft end is provided with eccentric cam, and eccentric cam is resisted against the other end of main brake piece.Rolling brake bar, eccentric cam rely on eccentric action main brake piece to produce braking force, and along with being rotated further of eccentric cam, the main brake piece is through the servo-actuated of adapter shaft driving auxiliary slipper, and two hoof pieces produce braking force thereupon simultaneously.Take-off the brake bar, eccentric cam can turn round and reset, and two hoof pieces reset thereupon.But, this structure, its eccentric cam is coaxial assembling with secondary slipper end; Do not have stressedly, only stressed, add the reason that the eccentric cam shape is intrinsic with main brake piece end; In the high vehicle speeds process, carry out under the situation of emergency braking, after braking procedure finishes; Stuck phenomenon can appear in eccentric cam and main brake piece end, can not reset, and causes brake locking.
Summary of the invention
Technical matters to be solved by this invention is to overcome the defective that prior art exists, and has proposed a kind of servant brake and has used eccentric cam shaft, is used for servant brake, the generation of the stuck phenomenon that can effectively prevent to brake.
A kind of servant brake of the present invention is used eccentric cam shaft, is made up of successively crank throw connecting portion, axle drive shaft, eccentric body; It is characterized in that: said eccentric body is flat-shaped cylinder, and its two narrow sides are arc surface; The distance that the longitudinal centerline of eccentric body is parallel with drive axis and maintenance is set.
Servant brake comprises fuse-box, main brake piece, secondary slipper, crank throw, eccentric cam shaft.Fuse-box is provided with eccentric cam shaft mounting hole and adapter shaft servo-actuated hole.One end of main brake piece and secondary slipper is hinged through adapter shaft, and adapter shaft is installed in the adapter shaft servo-actuated hole.Camshaft is installed in the eccentric cam shaft mounting hole, and the outer end of camshaft fuse-box is installed crank throw.Camshaft adopts servant brake of the present invention to use eccentric cam shaft.Establish extension spring between the other end end of main brake piece and secondary slipper, the end of main brake piece and secondary slipper is resisted against respectively on the broad side surface of eccentric body.
Further improvement project is: the end of eccentric body is provided with circular end cap, between eccentric body and axle drive shaft, establishes the circular platform that is connected.The effect of end cap is to guarantee the stable of eccentric body and main brake piece and secondary slipper mutual alignment relation.
During car brakeing, the pulling crank throw rotates eccentric body; Eccentric body is owing to eccentric structure, and eccentric body can drive outer rapidly the moving in end of main brake piece, and the main brake piece at first produces braking force; Along with being rotated further of eccentric body, the main brake piece can pass through the servo-actuated of adapter shaft driving auxiliary slipper, slowly outer the moving in end of the driving auxiliary of eccentric body meeting simultaneously slipper; All produce braking force up to two slipper, reach the purpose 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 near stress balance can not occur at glancing impact; Simultaneously; Because eccentric body all has motivator to main brake piece and secondary slipper, is in dynamic stress, therefore; Greatly reduce that not unclamp behind the brake locking be the generation of stuck phenomenon, have anti-stuck effect.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is explained further details.
Like Fig. 1,2,3, shown in 4, servant brake is made up of crank throw connecting portion 81, axle drive shaft 82, eccentric body 83 with eccentric cam shaft 8 successively.Eccentric body is flat-shaped cylinder, and its two narrow sides are arc surface; The longitudinal centerline 84 of eccentric body and drive axis 85 are parallel and keep the distance set.
Adopt the structure of the servant brake of eccentric cam shaft of the present invention: like Fig. 6,7, shown in 8.Servant brake 1 comprises fuse-box 2, main brake piece 12, secondary slipper 14, crank throw 10, eccentric cam shaft 8; Fuse-box is provided with eccentric cam shaft mounting hole 27 and adapter shaft servo-actuated hole 24.One end of main brake piece and secondary slipper is hinged through adapter shaft 5, and adapter shaft 5 is installed in the adapter shaft servo-actuated hole 24.Pad 3 is sleeved on the adapter shaft 5, jam nut 4 the insides, and jam nut 4 is sleeved on the adapter shaft 5, is used for fixing the axial motion of adapter shaft 5 on fuse-box 2.Adapter shaft 5 one ends are contained on main brake piece and the secondary slipper, are used for supporting main brake piece and secondary slipper and rotate, and an end is contained in the fuse-box adapter shaft servo-actuated hole 24, and the servo-actuated of main brake piece and secondary slipper when guaranteeing to brake increases braking force.Axis mounting hole 6 is used on the motor axis, installing brake and uses.
Camshaft 8 is installed in the eccentric cam shaft mounting hole 27; The outer end of camshaft fuse-box is installed crank throw 10; Crank throw jam nut 7 cooperates with crank throw lock screw 9 and is used to lock crank throw 10, and crank throw is fixed on the eccentric cam shaft 8, and the crank throw of the crank throw line mounting hole 11 of stopping is used for connecting the line of stopping.An end end is an eccentric body 83 in the camshaft fuse-box.Establish extension spring (claiming the slipper reset tension spring again) 18 between the other end end of main brake piece and secondary slipper, the end of main brake piece and secondary slipper is resisted against respectively on the broad side surface of eccentric body 83.
As shown in Figure 5, the end of eccentric body is provided with circular end cap 86, between eccentric body and axle drive shaft, establishes the circular platform 87 that is connected.The effect of end cap is to guarantee the stable of eccentric body and main brake piece and secondary slipper mutual alignment relation.
