Technical Field

The invention belongs to the field of brakes, and particularly relates to a brake shoe assembly with a wireless alarm function.

Background

The friction plate is an important device in a vehicle braking device and is one of parts which are worn out greatly in the use process of a vehicle, the friction plate is often used for forcing the vehicle to slow down and stop in the use process of the vehicle, so the friction plate is worn out more and thinner, and the friction plate must be replaced when the wear reaches a certain limit, otherwise, driving hidden trouble is caused, and the safety of drivers and passengers is endangered. Because the service conditions of all vehicles are different, some friction plates are worn quickly, and need to be replaced when the maintenance time is short, and some friction plates are used less, if the friction plates are replaced blindly during maintenance, waste can be caused.

Disclosure of Invention

In view of the above, an object of the present invention is to provide a brake shoe assembly with a wireless alarm function, which can actively alarm when a friction lining reaches a wear limit, and has high alarm accuracy, precise alarm and convenient arrangement.

In order to achieve the purpose, the invention provides the following technical scheme:

a brake shoe assembly with a wireless alarm function comprises a brake shoe and a friction lining laid on the inner circular surface of the brake shoe; the brake shoe or the friction lining is provided with a wireless alarm, and the wireless alarm is arranged on the brake shoe or the friction lining to monitor the thickness change of the friction lining and send an alarm signal to an instrument panel.

Further, the wireless alarm is arranged on the inner circular surface of the brake shoe, and the detection end part of the wireless alarm extends into the friction lining.

Further, the wireless alarm is arranged inside the friction lining and close to one side of the inner circle surface of the brake shoe.

The invention has the beneficial effects that:

by additionally arranging the wireless alarm in the brake shoe assembly, when the friction lining is worn to the limit thickness, the wireless alarm sends an alarm signal to the instrument panel after detecting. The alarm precision is high, and the alarm is timely; meanwhile, the production process only needs to use the traditional manufacturing process, the traditional braking part is not needed to be modified in the aspect of realizing the integral braking, and the brake is simple to manufacture, safe and reliable.

Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the means of the instrumentalities and combinations particularly pointed out hereinafter.

Referring to fig. 1 to 4, a brake shoe assembly with a wireless alarm function includes a brake shoe 1 and a friction lining 2 laid on an inner circular surface C of the brake shoe 1; the brake shoe brake pad further comprises a wireless alarm 3, wherein the wireless alarm 3 is arranged on the brake shoe sheet 1 or the friction lining sheet 2 to monitor the thickness change of the friction lining sheet and send an alarm signal to an instrument panel.

Specifically, the wireless alarm 3 with the active alarm function can detect the abrasion condition of the friction lining 2, when the friction lining 2 is abraded to the limit thickness, the wireless alarm 3 transmits information to the automobile ECU after detecting, alarm graphs or sounds are displayed on an instrument panel, and an alarm signal is actively sent out. This scheme is through setting up wireless alarm 3 on 1 or friction lining 2 on the brake shoe, can initiative and accurate detection friction lining 2's wear limit thickness to initiatively report to the police, thereby avoid influencing personnel's safety or leading to unnecessary loss of property because of friction lining 2 changes untimely. This scheme is applicable to the drum brake, and wireless alarm 3 is wireless initiative alarm.

The wireless alarm 3 has several mounting forms.
