Operation principle：
In use, control arm 2 is fixed in vehicle bridge, adjusting the shell 1 of arm can rotate around control arm 2, tool in big worm gear 3
There is spline, assembled with the splined shaft of arrestment mechanism, there is bolt set to be connected with braking effort source on shell 1.
When skidding, shell 1 is entirely pushed to be rotated around control arm 2, since ring gear 5 is fixed on control arm 2 not
It being moved together with shell 1, the pinion gear 1702 that connection is engaged with ring gear 5 is driven rotation, to drive small helical teeth 1701 to rotate,
Small helical teeth 1701 drives big helical teeth 12 to rotate, due to having gap between big helical teeth 12 and driving helical teeth set 11, particularly
There is gap between clearance groove and driving key 1101, since the resistance of resetting spring 13 is smaller, and drive worm set 9 and big worm screw
4 be discrete state, so small helical teeth 1701 drives big helical teeth 12 to rotate its prepsetting gap, when 12 prepsetting gap of big helical teeth is not covered
Automobile has been braked, has illustrated the brake clearance between brake drum and brake-shoe in normally braking range, if ought greatly tiltedly
12 prepsetting gap of tooth is covered, and automobile is not braked also, indicates that the brake clearance between brake drum and brake-shoe is excessive, the row of brake
Journey will increase, and 4 stress of big worm screw is more than the pressure of thrust spring 8 at this time, and clutch detaches at this time, and the stroke of augmenting portion is then
Big helical teeth 12 can be driven to rotate, but since clutch separation makes 11 idle running of driving helical teeth set, big helical teeth 12 and driving are oblique at this time
Tooth set 11 restores initial makeup location, i.e. prepsetting gap restores.
When releasing of brake, still stress, control arm 2 drive big helical teeth 12 to rotate backward to adjustment early period arm, clutch at this time
Mechanism is in discrete state, so that big helical teeth 12 is driven driving helical teeth set 11 and drives the whole idle running of worm set 9, and resetting spring 13
Elastic force keep big helical teeth 12 drive driving helical teeth set 11 prepsetting gap it is constant, when big worm screw 4 axial force be less than thrust bullet
When the pressure of spring 8, there are two types of situations：
1, brake clearance is in values：
At this point, control arm 2 drives pinion gear 1702 together with ring gear 5, to make big helical teeth 12 invert, to make unidirectional sliding mechanism
Reversed power transmission, and then clutch is made to be closed, and within a preset range due to brake clearance at this time, so torsion is insufficient to allow greatly
Worm screw 4 rotates, and resetting spring is surrendered at this time, makes big helical teeth 12 that driving helical teeth set 11 be driven to relatively rotate, it is default to turn over it
Gap adjusts arm return, is not above prepsetting gap, does not adjust, and adjustment arm keeps original state.
2, brake clearance is more than preset value：
Namely say above, if when 12 prepsetting gap of big helical teeth is covered, and automobile is not braked also, indicates brake drum and brake-shoe
Between brake clearance it is excessive, the stroke of brake will increase, and 4 stress of big worm screw is more than the pressure of thrust spring 8 at this time, at this time from
Organizational separation is closed, the stroke of augmenting portion can then drive big helical teeth 12 to rotate, but since clutch separation makes driving helical teeth set
11 dally, at this time big helical teeth 12 and 11 recovery initial makeup locations of driving helical teeth set, i.e. prepsetting gap recovery, corresponding at this time time
Cheng Wei：Control arm 2 drives pinion gear 1702 together with ring gear 5, to make big helical teeth 12 invert, to keep unidirectional sliding mechanism reversed
Power transmission, and then clutch is made to be closed, since the reaction force for the brake travel more walked early period is larger, so torsion makes big worm screw
4 rotations, to drive big worm gear 3 to rotate namely have adjusted the brake clearance between brake drum and brake-shoe, and big worm screw 4 drives
The gap that big worm gear 3 rotates is the excess gap between brake drum and brake-shoe, and so on gradually makes brake drum and system
Brake clearance between dynamic hoof is kept within a preset range.
Due to the adoption of the above technical solution, the beneficial effects of the invention are as follows：It is proposed a kind of automatic clearance adjuster,
Gap adjustment, one-directional rotation and clutch structure are arranged on big worm screw, are allowed to simple for structure, processing assembling it is simpler, it can be achieved that
For left and right adjustment arm other than shape shell, remaining all component is all general.And control arm driveline components can be in adjustment arm
Two sides arbitrary load.So the puzzlement of uncontrolled arm or so deflecting, keeps assembly more simple and reliable.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
