To the side that described brake disc is axial, described electromagnetic type proximity switch is positioned at the axial side of described brake disc and is fixedly mounted on
On the free end of described installation arm.
In the above-mentioned clamp-type brake unit with abrasion pre-warning, described support has elongated hole, the peace of described installation arm
Dress end to end is risen and is followed successively by thread segment, guide section and spacing section, described guide section has and coordinates with described elongated hole two side
Parallel surface, the gauge of spacing section is more than the width of described elongated hole.
In the above-mentioned clamp-type brake unit with abrasion pre-warning, alarm includes power supply, buzzer, flasher, described
Circuit loop is formed with electromagnetic type proximity switch, power series after buzzer and flasher serial or parallel connection.
Compared with prior art, this prior-warning device movement-less part, reliability is high, can not make drive axle entirety for the present invention
Any change, directly installs additional, reduces all kinds of management costs that change brings.Can effectively solve potential safety hazard and prevent brake
The problems such as damage.

Parts title and sequence number in figure:
Support 1, install arm 2, screw hole 21, spacing section 22, guide section 23, thread segment 24, nut 3, screw 4, electromagnetic type
Proximity switch 5, liner plate 6, friction plate 7, brake disc 8, electrical harness 9, power supply 10, buzzer 11, flasher 12, caliper body 13.
Detailed description of the invention
Specific embodiments is described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the clamp-type brake unit in the present embodiment, including brake and brake disc 8, brake disc 8 is positioned at
In the caliper body 13 of brake, the both sides of brake disc 8 have friction plate 7, and friction plate 7 is fixed on liner plate 6, and liner plate 6 is arranged on
In caliper body, brake disc 8 is fixing with drive shaft to be connected, and the caliper body 13 of brake is fixing with the axle housing of vehicle to be connected.
As Fig. 3 friction disc wear prior-warning device includes alarm and the electromagnetic type proximity switch 5 being connected with alarm, at folder
Caliper 13 is provided with the installing rack for installing electromagnetic type proximity switch 5, and electromagnetic type proximity switch 5 is arranged on installing rack.Peace
Shelving the support 1 including being fixed in caliper body and install arm 2, the one end installing arm 2 is installation end, and installation end is fixed on support
On 1, the other end is free end, and free end stretches to the axial side of brake disc 8, is provided with screw hole 21 on free end, electricity
Magnetic-type proximity switch 5 is positioned at the axial side of brake disc 8 and is fixedly mounted on installation by screw 4 with coordinating of screw hole 21
On the free end of arm 2.Having elongated hole on support 1, the installation end installing arm 2 is followed successively by thread segment 24, guide section 23 from end
With spacing section 22, guide section 23 has the parallel surface coordinated with elongated hole two side, the gauge of spacing section 22 be more than elongated hole
Width, thread segment 24 coordinates with nut 3 makes installation arm 2 be fixed on support 1, unclamp after nut guide section can in elongated hole edge
The length direction of elongated hole moves, thus regulates the position of free end, so reach to adjust electromagnetic type proximity switch and brake disc it
Between distance.
As in figure 2 it is shown, alarm includes power supply 10, buzzer 11, flasher 12, buzzer 11 connect with flasher 12 or
Concatenate formation circuit loop with electromagnetic type proximity switch 5, power supply 10 after parallel connection.
In the present embodiment, if the abrasion of friction plate 7 is in allowed band, namely its thickness is in the scope allowing use
In, during braking, friction plate 7 and liner plate 6 move to brake disc, but owing to the thickness of friction plate 7 is sufficiently thick, liner plate 6 can not enter into
In the induction range of electromagnetic type proximity switch；When friction plate gradually wears out, liner plate 6 side gradually shifts near proximity switch 5 sensitive surface,
During to specific thickness t, friction plate liner plate 6 and proximity switch 5 produce electromagnetic induction makes proximity switch connect, thus switches on power
10, buzzer 11, the path of flasher 12, produces sound and light alarm, points out operator's more renewal of facing renewal.This prior-warning device is without motion
Parts, reliability is high, drive axle entirety can not be made any change, directly install additional, reduces all kinds of management costs that change brings.
Can effectively solve the problems such as potential safety hazard and the damage preventing brake.
