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 mechanical disc brake that dish gap automatically adjusts.
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
The mechanical disc brake of section.
The mechanical disc brake that the utility model brake block automatically adjusts with disc gap, including friction plate 1, friction plate two
19th, base, right hoof block, disc, left hoof block, steel ball, housing, one-directional rotation bearing, limited block, pin, block, axle, rocking arm, big pressure
Contracting spring, small compression spring, torsionspring, big nut, primary nut.Left hoof block, right hoof block are arranged on the left and right ends of disc, its
It is characterised by, friction plate is arranged on the hoof block of left and right, and left hoof block is threadingly attached on 2 axles, and 2 axles pass through housing and bottom
Hole on seat；Housing is enclosed on left hoof block and contacted with the shaft part between base and with the shaft shoulder on axle；Axle on right hoof block passes through shell
Hole on body and base, is equipped with steel ball between right hoof block and housing, steel ball respectively with right hoof block inclined-plane, housing contact of incline plane；Gear
Block is fixed on right hoof block axle by pin, has a protrusion structure deeply to be connect into the groove of limited block and with groove top on block
Touch；For rocking arm on right hoof block axle, right hoof block axle right-hand member fixes rocking arm equipped with big nut；One-directional rotation bearing is housed on housing,
Limited block is on one-directional rotation bearing outer ring；Big compression spring is arranged between base and the shaft shoulder of axle；Small compression spring peace
Between left hoof block and housing；Torsionspring is arranged between base and rocking arm；Primary nut is arranged on axle right-hand member and and base
Contact.
The course of work for the mechanical disc brake that the utility model brake block automatically adjusts with disc gap is, in original state,
Gap length between left and right hoof block friction plate and disc is respectively 0.3 mm in size, and manpower rotates rocking arm, and rocking arm drives right
Hoof block is rotated counterclockwise, and the inclined-plane on right hoof block is acted on housing inclined-plane by steel ball, is caused right hoof block to move to the left and is connect
Touch disc after stop motion, be rotated further then as rocking arm, housing move right by axle drive left hoof block move right to
Contact disc, so far complete the action that left and right hoof block compresses disc, at the same rocking arm drive right hoof block rotate counterclockwise to it is left,
During right hoof block compresses disc, block rotates together with right hoof block, deeply to the protrusion in limited block groove on block
Form touch is to limited block groove bottom.With the progress of braking procedure, the friction plate of left and right hoof block constantly wears, and rocking arm continues
Right hoof block is driven to rotate counterclockwise, left hoof block moves right, and right hoof block is to left movement, and spring continues between left hoof block, right hoof block
Compression, block rotate counterclockwise with right hoof block and drive limited block and one-directional rotation bearing by contacting limited block groove bottom
Rotate counterclockwise, block, limited block, one-directional rotation bearing rotate counterclockwise equal angular simultaneously with right hoof block, are unclamping manpower
Afterwards, rocking arm rotates clockwise in the presence of torsionspring, drives right hoof block, block to be clockwise to block contact limited block
Groove top, because one-directional rotation bearing can only rotate counterclockwise and can not rotate clockwise, so limited block remains stationary as, so
Rear arm, right hoof block, block stop rotating clockwise.Simultaneously during rocking arm, right hoof block, block rotate clockwise, small
Left hoof block leaves 0.3 millimeter of disc to the left in the presence of compression spring, and right hoof block leaves to the right disc and moves 0.3 millimeter, so as to
Automatically compensate for, due to increasing gap caused by the hoof block friction disc wear of left and right, realizing the automatic regulating function in gap.
