Abstract
The invention discloses a safety device of a servo brake adjusting mechanism, which aims to overcome the disadvantage of the abrasion of a brake block caused by long-time use in the conventional servo brake. The safety device is arranged on an eccentric wheel adjusting mechanism passing through a connecting shaft between a main brake block and a secondary brake block. The safety device is characterized in that the secondary brake block is provided with a hole, a bolt shaft is placed in the hole, the bolt shaft passes through a brake shell and is fixed with a connecting plate through a nut, and the other end of the connecting plate is provided with a hole and is in clearance fit with the connecting shaft. By losing the nut, a shaft cover can be pulled to adjust the distance between the main brake block and the secondary brake block. Through the improvement on the servo brake adjusting mechanism, the structure of the adjusting mechanism on the servo brake is more reasonable and mature, safer, more reliable and longer in service life.
Description
Technical field
The present invention relates to a kind of servo brake adjusting mechanism, relate more specifically to the safety device of regulating mechanism.
Background technology
2,009,101,975,116 1 kinds of moped follow-up brakes that disclose, this servant brake arranges regulating mechanism between main brake piece 4 and secondary slipper 5, regulating mechanism is arranged on the eccentric wheel 19 that adapter shaft 8 periphery settings are connected with one, some recesses 20 from small to large are set on eccentric wheel 19, have waist shaped hole 10 on secondary slipper 5, on secondary slipper 5, anchor plate 16 is set, projection 21 is set on anchor plate 16, recess 20 on projection 21 and eccentric wheel 19 is complementary, owing to having waist shaped hole 10 on secondary slipper 5, projection 21 on the recess of eccentric wheel 19 and anchor plate 19 mates and leans on the effect of retracing spring 9 and be close to, period of service long and often spring 9 got rusty when losing efficacy, probably because main brake piece 4 and secondary slipper 5 long term wear regulate with eccentric wheel 19 recess 20 that increases to large position, make adapter shaft 8 on eccentric wheel 19, shaft-cup 18 is subjected to Vehicular vibration and may rotates, or artificial free curiosity is pulled generation main brake piece 4, secondary slipper 5 distances are dwindled, cause and wheel hub 7 excessive clearances, thereby weaken may existing of braking force, therefore the optimal effect of out of reach still.
A kind of adjuster for hub-brake of electric vehicle is disclosed, the projection 9 of arc is set on eccentric wheel 3, and eccentric wheel 3 is made of one with adapter shaft 2, nut 8 is set fixing with lock shell 11 on adapter shaft 2, this structure is used comparatively effective on the hub lock, and use on servant brake, certain difficulty is arranged.
Summary of the invention
the present invention relates to a kind of safety device of servo brake adjusting mechanism, comprise the lock shell, wheel hub, the main brake piece, secondary slipper, adapter shaft, shaft-cup, this structure is flexibly connected by adapter shaft between main brake piece and secondary slipper, adapter shaft is provided with the eccentric wheel of one, also be provided with shaft-cup on adapter shaft, have recess on eccentric wheel, secondary slipper has waist shaped hole, and on secondary slipper, anchor plate is set, anchor plate is provided with projection, shaft-cup is placed in outside the lock shell, and eccentric wheel arranges between lock shell and main brake piece, between main brake piece and secondary slipper, distance increases by the rotation of shaft-cup, recover the stability in the gap between main brake piece and secondary slipper and wheel hub, the present invention mainly arranges between adapter shaft and secondary slipper increases safety device again on regulating mechanism, safety device of the present invention is such realization: it comprises connecting panel, bolt shaft, the main brake piece, secondary slipper, nut, the lock shell, have waist shaped hole on the lock shell, have fixed orifice on secondary slipper, connecting panel one end has waist shaped hole, the other end has the hole with the adapter shaft coupling, bolt shaft one end fixes by secondary slipper hole and secondary slipper, the other end is provided with screw thread, bolt shaft is passed waist shaped hole on the waist shaped hole that has on the lock shell and connecting panel, secondary slipper is captiveed joint with the nut on bolt shaft with connecting panel, the connecting panel other end is flexibly connected by hole and adapter shaft, during use, unclamp nut, rotate shaft-cup, eccentric wheel on adapter shaft and the effect of secondary slipper upper support piece upper protruding block, distance between main brake piece and secondary slipper is enlarged, fastening nut again, thereby main brake piece and secondary slipper eccentric wheel effectively keep the distance, and the reasonable clearance between main brake piece and secondary slipper and wheel hub, connecting panel, shaft-cup can not rotate, engineered safety features structure of the present invention is very simple, and very easy to use, the structure of regulating mechanism is tending towards more reasonable, reliably, safety.

The specific embodiment
as Fig. 1, 2, 3, 4, the safety device of a kind of servo brake adjusting mechanism of the present invention comprises lock shell 1, wheel hub 22, eccentric cam 2, brake rod 3, main brake piece 4, secondary slipper 5, retracing spring 6, retracing spring 9, adapter shaft 8, brake rod 3 is fixing with eccentric cam 2, have waist shaped hole 7 on secondary slipper 5, also be provided with anchor plate 10 on secondary slipper 5, anchor plate 10 is provided with projection 11, adapter shaft 8 is provided with shaft-cup 12, also be provided with eccentric wheel 13 on adapter shaft 8, eccentric wheel 13 is provided with recess 14, projection 11 and recess 14 couplings, shaft-cup 12 is placed in the outside of lock shell 1, rotation by shaft-cup 12, and main brake piece 4 increases in the action pitch of eccentric wheel 13 recesses 14 with anchor plate 10 upper protruding blocks 11 with secondary slipper 5, the present invention mainly arranges safety device between adapter shaft 8 and secondary slipper 5, comprise by connecting panel 15, bolt shaft 16, main brake piece 4, secondary slipper 5, nut 17, lock shell 1, have waist shaped hole 18 on lock shell 1, one end of connecting panel 15 has waist shaped hole 19, the other end has the hole 20 that is complementary with adapter shaft 8, on bolt shaft 16 1 ends and anchor plate 10 and secondary slipper 5, hole 21 fixes in the lump, and the other end is provided with screw thread, waist shaped hole 19 on the hole 18 that bolt shaft 16 is passed lock shell 1 and connecting panel 15, secondary slipper 5 is fixing with connecting panel 15 use nuts 17, and the other end of connecting panel 15 is by coordinating with hole activity that adapter shaft 8 is complementary.
Use when adjusting, unclamp nut 17, rotate shaft-cup 12, by the effect of 13 recesses 14 of eccentric wheel on adapter shaft 8 with secondary slipper upper support piece 10 projections 11, distance between main brake piece 4 and secondary slipper 5 is increased, fastening nut 17 again, thereby the eccentric wheel of main brake piece 4 and secondary slipper 5 and regulating mechanism is keeping good performance.
