Description
Technical field
The invention belongs to automobile technical field, particularly relate to a kind of vehicle brake-holder block abrasion condition monitoring device.
Background technique
Along with China's economic development, people's living standard progressively improves, and family-sized car comes into huge numbers of families.Family-sized car brings people easily simultaneously, and the potential safety hazard of automobile becomes the problem that people are concerned about gradually.In numerous potential safety hazard, vehicle brake-holder block abrasion condition is detected as people are concerned about and the problem of headache.The traffic accident malfunctioning due to braking automobile is of common occurrence, brings huge loss to the lives and properties of people.How simple and effective detection braking plate abrasion condition becomes important and meaningful thing.
Domestic and international at present have multiple method for vehicle brake-holder block abrasion condition detection technique, and as coating, mass method etc., these methods are complicated, and cost is high.And have many submethods in daily life, as seen thickness, listening, sensation dynamics etc., all there is risk in these methods, should not use.
Summary of the invention
For the technical problem of above-mentioned existence, the invention provides a kind of vehicle brake-holder block abrasion condition monitoring device.Its reliable operation, with low cost, easily promote, can be people's traffic safety and provide safeguard.
The object of the invention is to be achieved through the following technical solutions:
Present invention resides in described vehicle brake-holder block and the sensor wire of three different wearing depths, voice plate and single-chip microcomputer are set near rubbing surface, described three sensor wires and voice plate are all connected on single-chip microcomputer, and three sensor wires are connected to both ends of power respectively by series resistors, described three sensor wires lay respectively at as the running-in wear degree of depth, moderate wearing depth and the greatest wear degree of depth.
Further, the distance a being positioned at the sensor wire distance friction plate rubbing surface of the running-in wear degree of depth described in is: 0.4 ± 0.01mm.
Further, the distance b being positioned at the sensor wire distance friction plate rubbing surface of moderate wearing depth described in is 0.8 ± 0.01mm.
Further, the distance c being positioned at the sensor wire distance friction plate rubbing surface of the greatest wear degree of depth described in is: 1.2 ± 0.01mm.
Beneficial effect of the present invention is:
The present invention by arranging the sensor wire of different depth on brake block, and to detect brake block wearing and tearing in various degree, real-time voice is reminded, and during to heavy wear, disconnect engine ignitor, automobile can not start, and reduces fault; Its structure is simple, reliable operation, with low cost, easily promote, reduce the potential safety hazard that people drive to go on a journey.

Fig. 2 is the structural representation of brake block of the present invention.
Fig. 3 is the plan view of Fig. 2.
Fig. 4 is the I portion enlarged diagram of Fig. 3.
In figure: 1. braking plate, L1 is the sensor wire of the running-in wear degree of depth, and L2 is the sensor wire of moderate wearing depth, and L3 is the sensor wire of the limiting wear degree of depth, and 8031 is mcs51 series monolithic, and T6668 is voice plate, and R1-R3 is resistance.
Embodiment
Describe the present invention below in conjunction with drawings and Examples.
Embodiment 1: as shown in Figure 1, present invention resides in described vehicle brake-holder block 1 and be disposed radially the sensor wire of three different wearing depths, voice plate and single-chip microcomputer 8031 near rubbing surface, described three sensor wires and voice plate are all connected on single-chip microcomputer 8031, and three sensor wires are connected to both ends of power respectively by series resistors, described three sensor wires lay respectively at as the running-in wear degree of depth, moderate wearing depth and the greatest wear degree of depth.
The described distance a being positioned at the sensor wire L1 distance friction plate rubbing surface of the running-in wear degree of depth is 0.41mm.
The described distance b being positioned at the sensor wire L2 distance friction plate rubbing surface of moderate wearing depth is 0.8mm.
The described distance c being positioned at the sensor wire L3 distance friction plate rubbing surface of the greatest wear degree of depth is 1.21mm.
In the present invention, three sensor wires are directly connected with 3 access ports of single-chip microcomputer 8031, and at the access port T6668 voice plate in succession of single-chip microcomputer 8031.After the saltus step of Single-chip Controlling signal is Actual level, the time delay of 16 more than ms must be had, otherwise T6668 voice plate is ignored.Article three, sensor wire can damage according to sequencing owing to wearing and tearing.In the process of automobile normal running, when Article 1 sensor wire damages, the braking plate of automobile is in running-in wear scope, and controller controls voice plate and reminds driver " to take care to drive "; When Article 2 sensor wire damages, the braking plate of automobile is in moderate wear range, and controller controls voice plate and reminds driver's " braking plate heavy wear suggestion is changed in time "; When Article 3 sensor wire damages, the braking plate of automobile is in the greatest wear limit, and controller controls voice plate and reminds driver that " ignition mechanism is locked, please stops immediately, changes braking plate! " simultaneously, the ignition mechanism of motor disconnects motor and can not start.
Embodiment 2: this example as different from Example 1: the distance a being positioned at the sensor wire L1 distance friction plate rubbing surface of the running-in wear degree of depth described in this example is 0.4mm.
The described distance b being positioned at the sensor wire L2 distance friction plate rubbing surface of moderate wearing depth is 0.81mm.
The described distance c being positioned at the sensor wire L3 distance friction plate rubbing surface of the greatest wear degree of depth is 1.19mm.
Embodiment 3: this example as different from Example 1: the distance a being positioned at the sensor wire L1 distance friction plate rubbing surface of the running-in wear degree of depth described in this example is 0.39mm.
The described distance b being positioned at the sensor wire L2 distance friction plate rubbing surface of moderate wearing depth is 0.79mm.
The described distance c being positioned at the sensor wire L3 distance friction plate rubbing surface of the greatest wear degree of depth is 1.2mm.
