Abstract
An alarming unit of automatic clearance-adjustment arm for automobile brake is used for alarming of monitoring over-worn of the friction disk of an automobile brake. The alarming unit of automatic clearance-adjustment arm for automobile brake includes an automatic clearance-adjustment arm for automobile brake, which is composed of an adjustment arm body, an adjustment arm worm and a worm gear. The automatic clearance-adjustment arm for automobile brake is equipped with a monitoring unit, and the monitoring unit is composed of a permanent magnetic signaling body and a Hall element. The permanent magnetic signaling body is equipped on the worm shaft path, and the Hall element is equipped on the adjustment arm body. The Hall linear circuit connects to the interior of a driving cap, and the alarming signal is displayed in audio, light or other modes. The utility model can sense the wearing capacity of the friction disk of the brake-shoe at any time. When the friction disk is still in normal use not far from damage, the alarming unit of automatic clearance-adjustment arm for automobile brake may send the alarming signal beforehand to remind the car's driver to alter the friction disk of the brake timely, and so as to ensure that the automobile is always provided with favorable brake performance.
Description
Technical field
The utility model relates to the drg technical field of conveying rotary motion, especially relates to monitoring the excessive worn-down warning device of automobile brake friction plate.
Background technology
Automobile is in the braking procedure that travels, and owing to the worn-down reason, the gap of its brake wheel and brake shoe brake cheek causes sensitivity to reduce in continuous increase; If same axle two-wheeled brake clearance difference will make the two-wheel braking force inhomogeneous, sideslip, the phenomenon of wagging the tail can take place during automobile brake, influence traffic safety.Be head it off, existing many people have designed various automatic regulating apparatuses, the patent of invention of a kind of " arm for adjusting automobile brake clearance automatically " that the applicant once proposed (publication number: CN1580601A), promptly belong to this type of device.The effect of these setting devices is behind the motor vehicle brake shoe friction disc wear, can carry out the compensation of automatic equivalent to the hoof drum gap of having amplified, make automobile often have good deceleration and stopping performance, but along with the continuous wearing and tearing of friction lining, compensation damages until friction lining fully also constantly carrying out, compensation also can not stop, only when hand inspection is found, just can be corrected,, will be caused the damage of brake system if find untimelyly.
Summary of the invention
The purpose of this utility model is the defective that exists at prior art, a kind of warning device of arm for adjusting automobile brake clearance automatically is provided, will damage preceding and also be in the normal use age at friction lining, signal in advance can give the alarm, remind automobile driver in time to reline the brakes, often have good deceleration and stopping performance to guarantee automobile.
For achieving the above object, the technical solution of the utility model is such: a kind of warning device of arm for adjusting automobile brake clearance automatically, comprise arm for adjusting automobile brake clearance automatically and monitor unit on it is set, said monitor unit is made up of the Hall element that is installed in the permanent magnetism signalling body on the worm screw diameter of axle and be installed on the adjusting arm body, wherein the permanent magnetism signalling body has n1, Hall element has n2, the Hall linear circuit is connected in the operator's compartment, with form display alarm signals such as sound, light.
Its principle of work is such: in arm for adjusting automobile brake clearance automatically, because the abrasion amount of brake shoe lining is directly proportional with the anglec of rotation of adjusting arm worm screw, so can measure the abrasion amount that the anglec of rotation of adjusting arm worm screw is come the perception brake shoe lining.In such scheme, revolve when the adjusting arm worm screw and to turn around, n1 permanent magnet and n2 Hall element, with they arrangements separately, various combined situation such as form alignment or stagger can produce N signal, the angle that on behalf of the adjusting arm worm screw, each signal turn over is about 360 °/N, by sending the quantity of signal, just can know how many angles the adjusting arm worm screw has rotated, also just equal to have known the abrasion amount of brake shoe lining.
Owing to adopted technique scheme, the warning device of a kind of arm for adjusting automobile brake clearance automatically of the present utility model, at any time the abrasion amount of perception brake shoe lining, will damage preceding and also be in the normal use age at friction lining, signal in advance can give the alarm, remind automobile driver in time to reline the brakes, often have good deceleration and stopping performance to guarantee automobile.
