Description
Technical field
The brake apparatus of a kind of bicycle, tricycle, electric car is the utility model is related to, especially a kind of brake block and dish
The double-side driving of dish gap adjust automatically pulls mechanical disc brake.
Background technology
The problem of existing Bicycle dished brake is deposited has：First, when using the structure of one side driving, it may appear that disk is variable
Shape causes friction plate scratch disk to produce the phenomenon of drag so as to produce bounce；Second, the gap between existing disc brake hoof block
Increase with the abrasion of hoof block friction material and be unable to adjust automatically, this causes the idle stroke of brake lever constantly to increase, especially
It is force amplifying function when this meeting large effect designs for mechanical disc brake.
Utility model content
The purpose of this utility model is just to provide that a kind of cost is low, and braking moment is big, and brake block is adjusted automatically with disc gap
Whole double-side driving pulls mechanical disc brake.
A kind of brake block of the utility model and the double-side driving of disc gap adjust automatically pull mechanical disc brake, including left hoof
Block, bolt 1, left friction plate, right friction plate, disc, housing, mounting seat, steel wire rope, positioning screw, handle spacing collar, handle
It is the unidirectional needle bearing of axle, handle, handle, bolt 2, active voussoir, spacing collar, unidirectional needle bearing, rocking arm, compression spring, fixed
Position axle, by dynamic voussoir, steel ball, small compression spring.Left friction plate, right friction plate are arranged on the left and right ends of disc, and its feature exists
In left friction plate is arranged on left hoof block, and left hoof block is connected on housing by stove bolt；Right friction plate is arranged on housing bore
It is interior, and contacted with active voussoir left end；Through the hole on housing, axle right-hand member has a convex tendon for axle on active voussoir, active voussoir with
Steel ball is housed, steel ball is respectively with active voussoir inclined-plane, by dynamic voussoir contact of incline plane between dynamic voussoir；Shell is arranged on by dynamic voussoir
In body opening, and it is fixed in housing neck by inserting；Unidirectional needle bearing is installed, outside unidirectional needle bearing in housing right-hand member hole
Circle is interference fitted with housing bore, unidirectional needle bearing inner ring and spacing collar interference fit, is fixed on housing equipped with positioning screw single
To needle bearing outer ring；Spacing collar left end is provided with 3 apertures being uniformly distributed along the circumference, and hole is built with small compression spring, in spacing collar
Hole is provided with neck, and the right-hand member of neck contacts with the convex tendon on active voussoir axle, and convex tendon can rotate in neck；Active voussoir axle is right
End is equipped with rocking arm, and rocking arm is fixed on active voussoir axle by king-bolt；Compression spring is housed between rocking arm and housing；Steel wire rope
One end is fixed on rocking arm, and is fixed on through the hole in compression spring and housing, the other end on handle；There is a hole on handle,
There is convex tendon in hole, convex tendon is stuck in handle spacing collar groove and rotated；The spacing ring gap of handle, which coordinates, to be arranged in handle hole, handle
Spacing collar endoporus is interference fitted with the unidirectional needle bearing outer ring of handle；The unidirectional needle bearing inner ring of handle is matched somebody with somebody with Handle axis interference
Close；Locating shaft passes through the hole on housing and mounting seat, is to be threadedly coupled between locating shaft and mounting seat, locating shaft and housing
It is that gap coordinates between hole, housing can the left and right slip on locating shaft；
The utility model brake block and the course of work for pulling mechanical disc brake of disc gap adjust automatically are, in initial shape
State, the gap between left and right friction plate and disc are respectively 0.25 mm in size, and manpower rotates handle counterclockwise, in handle hole
Convex tendon is rotated in handle spacing collar groove, while handle is rotated counterclockwise by rope belt motion rocker arm, compression spring compression,
Rocking arm drives active voussoir axle to rotate counterclockwise, and the inclined-plane on active voussoir is acted on by dynamic voussoir inclined-plane by steel ball, is led
The active voussoir right friction plate of movement progress moving contact disc to the left to the left is caused, then stop motion, is driven then as handle
Rocking arm is rotated further, and promotes housing to move right in the presence of steel ball by dynamic voussoir, housing drives left hoof block by stove bolt
Move right, left hoof block promotes left friction plate to move right to contact disc, so far completes left and right friction plate and compresses disc
Action, handle hole inner convex rib touches handle spacing collar groove top, while drives active voussoir axle to rotate counterclockwise in rocking arm
During compressing disc to left and right friction plate pressure, the convex tendon on active voussoir axle turns to contact in spacing collar neck and connect
Touch neck left end.With the progress of braking procedure, left and right friction plate constantly wears, and continues to rotate counterclockwise handle, in handle hole
Convex tendon is rotated counterclockwise by handle spacing collar groove bands fixed handle spacing collar, and rocking arm continues to drive active voussoir axle counterclockwise to turn
Dynamic, left friction plate moves right, and for right friction plate to left movement, the convex tendon on active voussoir axle drives spacing collar and one-directional rotation axle
Hold inner ring to rotate counterclockwise, active voussoir axle, spacing collar, unidirectional needle bearing inner ring rotate counterclockwise equal angular, hand simultaneously
Handle, handle spacing collar also rotate counterclockwise equal angular simultaneously, are acted in release on handle after manpower, rocking arm is in compression spring
In the presence of rotate clockwise, rocking arm drives active voussoir, handle to rotate clockwise, due to the unidirectional needle bearing outer ring of handle only
It can rotate counterclockwise and can not rotate clockwise, so handle spacing collar remains stationary as, handle hole inner convex rib, which turns to, to be touched
Handle spacing collar groove stops operating behind top.Simultaneously as unidirectional needle bearing inner ring can only rotate counterclockwise and can not be suitable
Hour hands rotate, so spacing collar remains stationary as, then the convex tendon on active voussoir axle is clockwise to contact spacing collar groove
Right-hand member, rocking arm stop rotating clockwise.During being rotated clockwise in rocking arm, handle, active voussoir axle rotates clockwise
Angle with by original state change to the angle phase that rotates counterclockwise of active voussoir axle during left and right friction plate clamping disc state
Deng, the angle that handle rotates clockwise with it is counterclockwise to handle during left and right friction plate clamping disc state by original state change
The angle of rotation is equal, so left friction plate leaves 0.25 millimeter of disc to the left in the presence of disc counter-force, right friction plate to
0.25 millimeter of disc is left on the right side, so as to compensate for, due to increasing gap caused by left and right friction disc wear, realizing gap automatically
Automatic regulating function.
