Abstract
The utility model discloses a disc brake wear warning device for a commercial vehicle, which comprises a singlechip, a power supply module, a plurality of disc brake wear sensors and a plurality of warning devices which have the same number, wherein the power supply module is connected with the singlechip, and a grounded terminal of the singlechip is grounded; one end of each brake wear sensor is connected onto the singlechip, and the other end of each brake wear sensor is grounded; one end of each warning device is connected onto the singlechip, and the other end of each warning device is grounded; and when detecting that the disc brake wear sensors are at a safe limit value, the singlechip drives the corresponding warning devices to give an alarm. The warning device can give an alarm when a disc brake pad is worn to the safety limit value, thereby greatly reducing the probability of loss of brake control.
Description
Technical field
The utility model belongs to the vehicle fitting equipment technical field, is specifically related to a kind of commercial car disc type brake wearing and tearing alarm.
Background technique
Commercial car in use for some time, disc brake pad on the car has wearing and tearing in various degree, and the driver only changes disc brake pad with the personal experience generally speaking, if change untimely, easily cause the brake under the emergency to lose efficacy, cause serious traffic accident.
Summary of the invention
The purpose of this utility model provides a kind of commercial car disc type brake wearing and tearing alarm, and it is alert to may wear to safety limit limit value Times at disc brake pad, has significantly reduced the probability out of control that brakes.
The technological scheme that the utility model adopted is, a kind of commercial car disc type brake wearing and tearing alarm, comprise single-chip microcomputer, be connected with power module on the single-chip microcomputer, and identical a plurality of disc type brake wear sensors and the alarm of quantity, power module is used for providing power supply to single-chip microcomputer, the grounding end ground connection of single-chip microcomputer, one end of a plurality of disc type brake wear sensors is connected on the single-chip microcomputer and the other end ground connection, one end of a plurality of alarms is connected on the single-chip microcomputer and the other end ground connection, single-chip microcomputer drives corresponding alarm equipment alarm when detecting the disc type brake wear sensor and be in the safety limit limit value.
Single-chip microcomputer, power module and a plurality of disc type brake wear sensor and alarm are installed in the same housing.Alarm is the LED lamp.The quantity of disc type brake wear sensor and alarm is 8.
A kind of commercial car disc type brake wearing and tearing of the utility model alarm can be by detecting the abrasion condition of multichannel disc brake pad, and it is out of control effectively to avoid braking.The one end ground connection the other end of a plurality of disc type brake wear sensors is connected with one-chip machine port, and like this, when commercial car of the present utility model being installed normally moving, the monolithic function detects ground signalling in real time.Because commercial car in use for some time, disc brake pad has wearing and tearing in various degree, when the wearing and tearing disc brake pad wears up to margin of safety, the disc type brake wear sensor can damage and open circuit, single-chip microcomputer detects less than ground signalling, drive corresponding alarm equipment alarm newspaper, need in time to change brake block thereby remind this car brake disc of driver to wear and tear, avoid so the brake that causes out of control.To sum up, the utility model reliable in function, easy for installation, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model commercial car disc type brake wearing and tearing alarm.
Wherein, 1. power module, 2. single-chip microcomputer, 3. disc type brake wear sensor, 4. alarm.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, the utility model comprises a kind of commercial car disc type brake wearing and tearing alarm, comprise single-chip microcomputer 2, be connected with power module 1 and a plurality of disc type brake wear sensor 3 and alarm 4 on the single-chip microcomputer 2, disc type brake wear sensor 3 is identical with the quantity of alarm 4.Power module 1 is used for providing power supply to single-chip microcomputer 2, the grounding end ground connection of single-chip microcomputer 2, and an end of a plurality of disc type brake wear sensors 3 is connected on the single-chip microcomputer 2 and the other end ground connection, and an end of a plurality of alarms 4 is connected on the single-chip microcomputer 2 and the other end ground connection.The signal of single-chip microcomputer 2 intermittent scanning disc type brake wear sensors 3, and when detecting disc type brake wear sensor 3 and be in the safety limit limit value, drive corresponding alarm 4 and report to the police.Wherein, alarm 4 is the LED lamp.The quantity of disc type brake wear sensor 3 and alarm 4 is 8.
Power module 1, single-chip microcomputer 2 and disc type brake wear sensor 3 and alarm 4 are installed in the same housing.This sample device level of integration height is convenient to install and use.
The utility model is installed on the rocker switch reserved opening on the indoor instrument panel of vehicle drive in use, and power module 1 is connected with key operation power supply DC24V.Under the situation of the normal operation of commercial car, single-chip microcomputer 2 is detected to be the ground signalling of disc type brake wear sensor 3; When disc type brake wear sensor 3 causes signal to disconnect because of wearing up to margin of safety, 2 detections of single-chip microcomputer are less than the ground signalling of disc type brake wear sensor 3, and the luminous warning of control corresponding LED lamp, disconnect with the wear sensor of reminding this position of user, need in time to change brake block.
