Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a perspective view of an alarm probe, the alarm probe comprises a head part 1, a middle part 3 and a tail part 4, wherein the head part 1 is provided with a through hole 2, and a section of wire of an alarm wire harness can pass through the through hole 2 and is fixed at the head part of the alarm probe. The alarm probe is made of high-temperature-resistant friction materials, the probe is fixed on a steel back of the friction plate, when the friction plate is worn to the limit position, the head 1 of the alarm probe is also worn, meanwhile, a lead in the through hole 2 is also worn off, and then the alarm is given through circuit breaking. The left end surface of the head part 1 is long and protrudes from the left end surfaces of the middle part 3 and the tail part 4.

Fig. 2 is a front view of the alarm probe, 1 is a head part, the upper part of the head part is trapezoidal, the lower part of the head part is rectangular, and a through hole 2 is arranged in the trapezoidal area at the upper end. The middle part 3 is rectangular, the width is narrower than the head part, and the tail part 4 is rectangular as a whole and slightly wider than the middle part 3. The shape is convenient for fixing the alarm head on the brake pad and arranging the U-shaped clamping piece.

Fig. 3 is a rear view of the alarm probe, and the head 1 is provided with a through hole 2 and a groove 3.

After the alarm wire harness (wire) passes through the through hole, the alarm wire harness (wire) can be placed in the groove, so that the alarm probe is convenient to mount, and the stability is higher.
