TECHNICAL FIELD [0001] The present invention relates to a wear detection member mounting apparatus for a brake pads of a vehicle,

The present invention relates to a wear detection member mounting apparatus for informing a replacement timing of a brake pad for a vehicle, and more particularly to a mounting apparatus for temporarily fixing a disc brake pad, And a pressing means for pressing down the sensor-engaging rivet when the disc brake pad is mounted by the contact sensor, so that the sensor can be effectively engaged and fixed to the disc brake pad The present invention relates to a wear detection member mounting apparatus for informing a replacement timing of a brake pad for a vehicle.

Generally, a brake mounted on a vehicle is for reducing a vehicle during running or for stopping or stopping the vehicle, and includes a drum type hydraulic brake and a disk type hydraulic brake. The disk brake is a disk type The disk is pressed strongly from both sides to the pad to obtain the braking force.

1, the disc brake is divided into a housing 10 in which the piston 20 is installed and a carrier 40 which is fixed to the vehicle body and on which the pad plates 50 and 60 are installed. A cylinder 11 is formed in the housing 10 and a piston 20 which moves back and forth by the hydraulic pressure transmitted through the inlet 12 is formed. On the other hand, fastening holes 13 are formed at both ends of the housing 10 for fastening with the carrier 40.

An installation space 42 is formed in the center of the carrier 40 and a pair of pad plates 50 and 60 with pads 51 and 61 are provided. The pad plates 50 and 60 are spaced apart from each other by a predetermined distance so as to move back and forth in the installation space 42. The inner and outer pads 50 and 60, And an outer pad plate 60. The other surface of the outer pad plate 60 is in contact with the fingers 15 extended from the housing 10 and the outer surface of the outer pad plate 60 is in contact with the outer surface of the piston 20. [ And is configured to advance inward when braking. A disc-shaped disc 70 is inserted between the pair of pads 51 and 61, and a part of the outer periphery thereof is inserted and rotated together with a wheel (not shown) with a certain clearance therebetween.

The housing 10 provided with the piston 20 and the carrier 40 provided with the pad plates 50 and 60 are slidably engaged with each other. First, as described above, fastening holes 13 are formed at both ends of the housing 10, and fastening grooves 41 of a predetermined depth are also formed at both ends of the carrier 40 so as to face the fastening holes 13 Consists of. One end of the guide rod 30 is fastened to the fastening hole 13 with the bolts 14 and the other end is slidably inserted into the fastening groove 41 so that the carrier 40 fixed to the vehicle body, The housing 10 is engaged. Reference numeral 21 denotes a seal for restoring the piston 20 when the cylinder 11 is released to the hydraulic pressure.

When the driver presses the brake pedal (not shown) when the automobile having the general disk brake configured as described above is operated, the hydraulic pressure acts from the master cylinder (not shown), and this hydraulic pressure continues to flow through the inlet 12, Lt; / RTI > The inner pad 51 attached to the inner pad plate 50 is momentarily pressed onto the disk 70 by the advance of the piston 20 by the oil pressure. Since the hydraulic pressure is present in the cylinder 11, the housing 10 itself, which is slidably coupled to the carrier 40 using the guide rod 30, moves in the opposite direction, The outer pad 61 attached to the outer pad plate 60 is pressed against the disk 70 to perform the braking action. When the brake pedal (not shown) is released, the piston 20 is restored to its original position due to the elastic restoring force of the seal 21, and the disc 70 and the pads 51 and 61 are spaced apart from each other by a predetermined distance.

On the other hand, if the braking action is repeated, the pads 51 and 61 are continuously worn out due to the friction with the disc 70, and the brake performance is lowered. Therefore, in order to recognize the replacement time of the pad plates 50 and 60 with the pads 51 and 61, the wear of the pads 51 is recognized on the pad plate 50 as shown in FIG. A pad abrasion detecting member 80 is provided. This will be described in more detail with reference to the accompanying drawings.

The pad wear detecting member 80 is fixed to one end of the pad plate 50 by one end by riveting means 81 and the other end is bent and extended so as to face the side surface of the disk 70 at a predetermined distance have.

Therefore, when the disc brake is used for a long period of time, the pad 51 for pressing the disc 70 on both sides will gradually wear, and when the pad 51 is worn out as shown in FIG. 3, The other end of the sensing member 80 is in contact with the side surface of the disk 70.

At this time, a metal frictional sound is generated due to the contact between the disk 70 and the pad wear detection member 80, which rotate together with the wheel (not shown), and the friction sound is heard by the driver, The replacement of the pad plate 50 is recognized.

Meanwhile, since the pad wear detection member is fixed to the one end of the pad plate by the riveting means, conventionally, the riveting means is manually fixed, which results in a problem of low working efficiency.

In other words, conventionally, in a state where the pad wear detection member is temporarily coupled to the pad plate and the rivet is inserted, the rivet compression means is lowered in a state of being attached to the rivet compression means to fix the pad wear detection member, The problem was that it was very inconvenient to work because it had to be precisely riveted to the pressure tip of the riveting tool manually.

The disc brake pad 100 includes a pad friction material 110 and a pad plate 110. The pad friction material 110 made of synthetic resin is wrapped and fixed by a pad plate 120 made of a metallic material.

The wear detection member 10 for a brake pad is in the form of a trapezoid and is coupled to one side of the brake pad 100 so that when the pad friction material 110 constituting the brake pad 100 is worn out more than the reference, It is in contact with the disk to generate noise.

The abrasion detecting member coupling rivet 20 is inserted and coupled through the center axis of the wear detection member 10 for the brake pad so as to fix the wear detection member 10 for the brake pad to one side of the brake pad 100, So that the wear detection member 10 remains fixed to the brake pad 100. [

That is, the light amount data outputted from the infrared ray receiving means is read by the dust measurement control unit, and the light amount of the infrared light emitting means is automatically controlled based on the read light amount data, so that the sensitivity adjustment is automatically maintained constant. So that the measurement can be performed while maintaining the sensitivity state.

In other words, the dust measurement control section C determines that the degree of contamination is high when the amount of received light of the infrared ray receiving means B is low, and outputs a control signal to increase the light amount of the infrared ray transmitting means A If the amount of light received by the infrared ray receiving means C is too high, a contamination-free state or a precise measurement becomes difficult. Therefore, a control signal is outputted so as to lower the light amount of the infrared ray transmitting means A That is, it is necessary to keep the amount of infrared transmission light in an appropriate state. The infrared ray amount measured through the infrared ray receiving means is accurate and the dust amount can be more precisely predicted. Therefore, the dust amount data measured by the dust measurement control unit of the present invention can output the dust measurement result with high reliability.

It is needless to say that the number of the fitting holes 6a and the weight adjusting pins 6b may be varied according to need. In the embodiment of the present invention, three fitting holes 6a and three weight adjusting pins 6b ), So that the explanation can be made more convenient.

In addition, according to the present invention, when dust is detected as a reference or more and a notification situation occurs, the dust measurement unit (3000) displays the notification status through the communication signal automatic output unit (1000) The automatic output unit 1000 includes a power supply unit 1110, a first switching transistor, a second switching transistor, a third switching transistor, a fourth switching transistor, a relay switch, a first circuit connection switch sw1, A second circuit connection switch sw2, and a communication control unit 1120. [

The power source unit 1110 applies power to its own power source.

The first switching transistor Q1 switches the circuit according to a switching signal input to the base.

The second switching transistor Q2 operates in accordance with the operation of the first switching transistor and switches the power source output from the power source unit.

The third switching transistor Q3 switches the circuit according to a switching signal input to the base.

The fourth switching transistor Q4 is provided on the other side of the output terminal of the power supply unit to switch the power supply unit output from the power supply unit.

The relay switch RL1 is coupled to the output terminal of the fourth switching transistor and generates a magnetic force when the fourth switching transistor is switched.

The first circuit connection switch sw1 performs a function of energizing the circuit by pulling the iron piece by the relay switch.

The second communication signal output power switch sw2 serves to induce a communication signal to be output through the communication signal output unit 1150 by supplying power to the communication signal output control unit 1140 while the iron wire is pulled by the relay switch do.

The communication controller 1120 switches the third switching transistor and the fourth switching transistor to switch the relay switch so that the first circuit connection switch and the second communication signal output power switch are switched, A first circuit connection switch configured to switch the first switching transistor and the second switching transistor while turning off the switching transistor and the fourth switching transistor and to turn off the relay switch and simultaneously to be interlocked with the first switching transistor and the second switching transistor And maintains the communication state by continuing the switching state of the second communication signal output power switch.

In addition, the present invention is characterized in that it comprises a circuit board 1131 for operation, a wire piece 1132 for connection to a power supply for operating a communication signal control unit, a first resilient holding means 1133, a second resilient holding means 1134, (1133a), and a manual operation switch (1135).

The circuit-operating piece 1131 contacts the first circuit connection switch sw1 and relays the power delivered from the second switching transistor to continue the flow of power.

The communication signal output control unit power connection iron piece 1132 is designed to operate in conjunction with the circuit operation iron piece 1131. When the circuit operation iron piece 1131 is turned on, power is supplied to the communication signal output control unit 1140 Thereby inducing the communication device to operate.

The first elastic holding means 1133 is provided at the lower end of the circuit operation steel plate 1131 so that the first circuit connection switch sw1 and the circuit operation wire 1131 are always kept in the off state when the relay switch is not operated .

The second elastic holding means 1134 is installed on the upper portion of the first circuit connecting switch sw1 and is spaced apart from the first elastic holding means by a predetermined distance. When the relay switch is operated, the circuit breaker 1131 is pulled to be coupled with the first resilient holding means 1133 while the first resilient holding means is overlapped, and at the same time, the first circuit connecting switch sw1 is switched So that even if the operation of the relay switch is stopped, the state of attaching the circuit breaker 1131 continues to maintain the power supply state through the first switching transistor and the second switching transistor. At this time, when the circuit breaker 1131 is operated by the operation of the relay switch, the communication piece 1132 is automatically operated to output the communication signal to the outside.

The gap maintaining means 1133a guides the second elastic holding means 1134 and the first elastic holding means 1133 to be engaged with each other while maintaining a constant gap without being directly coupled to each other when the first elastic holding means 1134 and the first elastic holding means 1133 are engaged, 1133 and the second resilient holding means 1134 can be more smoothly separated from each other by the action of the gap maintaining means at the time of disassembly. If the gap maintaining means is not present, the first elastic holding means 1133 and the second elastic holding means 1134 are directly attached to each other, so that mutual separation becomes difficult later. Accordingly, in the present invention, the first elastic holding means 1133 and the second elastic holding means 1134 can be easily separated by further providing the gap holding means 1133a.

The manual operation switch 1135 is connected to a wire for circuit operation and a wire for connection to a communication signal output control unit. When the user operates the wire to interrupt the operation of the communication signal, So that the operation of the communication signal output unit is stopped so that the communication signal is no longer output.

Hereinafter, the operation of the communication signal automatic output unit 1000 will be described.

First, a control relation for outputting a communication signal will be described. In the control unit, a power is applied to the third switching transistor and the fourth switching transistor to operate the relay switch RL1. Accordingly, the first circuit connection switch sw1 and the communication signal output power switch sw2 are turned on by the operation of the relay switch, and the power is applied to the communication signal output control unit 1140 to display the communication signal.

When the first circuit connection switch sw1 is operated, the control unit interrupts the operation of the third switching transistor and the fourth switching transistor to cut off the operation of the relay switch, and simultaneously operates the first switching transistor and the second switching transistor.

On the other hand, if the operator turns off the first circuit connecting switch and the communication signal output power switch in the middle of outputting the communication signal, the control unit recognizes this, and then the third switching transistor and the fourth switching transistor are operated, It is possible to keep the closed circuit while moving the iron piece and at the same time return the power outputted to the communication signal control part 1140 to continuously operate the communication signal output part 1150.

That is, according to the present invention, if the notification factor is not solved, the communication signal is continuously output to induce the notification factor to be solved.

That is, when a switching signal is applied to the third switching transistor, the fourth switching transistor, the first switching transistor, and the second switching transistor in the control unit, the communication signal is automatically output by returning the power source again, It is possible to induce the operator to reliably solve the cause of the communication signal.

If it is no longer necessary to output a communication signal, the control unit no longer applies a power supply signal to the first switching transistor, the second switching transistor, the third switching transistor, and the fourth switching transistor. ) Can be manually operated by a user to interrupt the communication signal.
