In the optinal plan of the present embodiment, tooth-like recesses 13 are cone mark of mouth slot, straight-tooth groove or sawtooth grooves.
The working principle of the utility model embodiment: 2 inner hole of worm gear of the utility model is spline, when assembly and brake
The spline of camshaft matches, and the other end links together air chamber push rod 15 with the utility model by flat-headed pin, is mounted in shell
The control arm 5 concentric on body 1 and with worm gear 2 is fixed on brake camshaft, is thereby realized and is installed on the utility model
On camshaft type drum brake.The control panel 4 of the fluted notch of marginal belt is fixed together with control arm 5, when work not
It is rotated with shell 1.When braking, the air chamber push rod 15 of brake pushes the shell 1 of the utility model, and shell 1 passes through the snail in it
Bar axis 3 drives worm gear 2, and worm gear 2 drives brake-toggle shaft, to make cam rotate an angle and brake lining is driven to be pressed
On brake drum, torque required for braking is generated.When the gap of brake lining and brake drum, (automatic adjusting arm to be adjusted
Gap) in presetting range when (brake lining is without state of wear), brake chamber 14 pushes the corner value of the utility model to get togather
The angular clearances value of corresponding control panel 4 edge groove notch and 7 hooked projection of rack gear, control panel 4 is static and rack gear 7 is by reset bullet
Spring 9 is pressed on shell 1 to be rotated within the scope of this angular clearances with shell 1, this hour rack 7 and shell 1 do not have relative displacement, this
When without gap adjust；When the own abrasion of brake lining is that brake clearance becomes larger, the stroke of air chamber push rod 15 increases, this is practical
Novel corner also increases accordingly therewith, at this point, brake chamber 14 pushes the corner value of the utility model to be greater than corresponding angle
Gap width, rack gear 7 with shell 1 in addition to rotating together with, due also to the downside of 4 groove of control panel pushes the hooked projection on rack gear 7
Make 7 compression reseting spring 9 of rack gear and opposite shell 1 move up a variate-value, this value with the degree of wear of brake lining and
Variation.In the process, it is not able to rotate since the rotation of shell 1 is pressed on worm shaft 3 to the right on shell 1, while clutch shaft
Set 10 is separated with worm shaft 3, and rack gear 7, which is moved and driven with respect to shell 1, adjusts gap gear 6, and gap gear 6 is adjusted to keep unilateral bearing 11 positive
(the without hindrance torque direction of unilateral bearing 11) rotates corresponding angle.When releasing braking, the utility model resets, worm shaft 3
Right end and shell 1 are detached under the action of holddown spring 8, and left end is re-engaged with clutch axle sleeve 10, and rack gear 7, which also drives, adjusts gap tooth
Wheel 6 resets under the action of reset spring 9, due to the single effect of unilateral bearing 11, makes to adjust gap gear 6, clutch axle sleeve 10 logical
It crosses unilateral bearing 11 to be linked together in return with worm shaft 3, move simultaneously.It adjusts the rotation of gap gear 6 and passes through tooth-like recesses
13 drive worm shaft 3 to rotate, and worm drive worm gear 2 reaches automatic so that brake camshaft be made accordingly to rotate an angle variables
The effect for compensating the gap of brake lining and brake drum, just completes the vehicle brake gap adjust automatically of the utility model at this time
One duty cycle of arm.

The automobile for being equipped with automatic adjusting arm currently on the market does not all have automatic adjusting arm failure detection and warning function, uses
Family often can only judge whether automatic adjusting arm fails from conditioning function by the quality of braking effect.But when user is obvious
When feeling that braking effect is bad, for some time away from automatic adjusting arm self-regulated disabler, brake efficiency is largely
Decline, traffic safety risk at this time are very big.
Specifically, automatic adjusting arm is to increase excessive gaps automatic compensation function on the basis of hand regulation arm, only
It can be turned down when brake clearance is excessive to normal range (NR), will not be tuned up automatically when brake clearance is too small.From conditioning function
In normal situation, the angle, θ that automatic adjusting arm is turned in complete braking is certain, i.e. maximum of 14 push rod of brake chamber
Stroke S is certain.It therefore can be using the range of air chamber push rod 15 as foundation whether detection automatic adjusting arm failure.
If the stroke of air chamber push rod 15 has been more than that range under normal circumstances can determine that automatic adjusting arm from conditioning function when braking
Failure.
Specifically, sensor is made of sensor body 16 and sensor activity end 17, sensor body 16 is fixed on gas
On room, sensor activity end 17 is mounted on the junction of automatic adjusting arm Yu air chamber push rod 15.
By the stroke of air chamber push rod 15, input controller judges sensor in electrical signal form when automobile brake, and leads to
Crossing CAN bus will be as the result is shown in instrument, if the stroke of air chamber push rod 15 is greater than range (fixed value), i.e. display is automatic
Adjustment arm self-regulated disabler is simultaneously alarmed, and user can learn this situation in time.In the embodiment for alarm only give in addition to
This scheme of instrument, as an alternative solution, loudspeaker or LED light also can be used in instrument, and there is the device of prompt facility to be replaced.
