Abstract

PURPOSE: To damp effectively and surely the vibration of a friction member slidably making contact with a disk in braking and eliminate completely the creak of a disk brake caused by the vibration. CONSTITUTION: The vibration of a pad 1 in the tangential direction of a disk is detected by a vibration detector 6 and the detecting signal is inputted to a control circuit 5. Also, a torque member 2 is provided with a cylinder 9 to supply oil pressure from an oil pressure generator 4 so that a restricting piston 3 is inserted in the cylinder 9. A signal is sent from the control circuit 5 to the oil pressure generator 4 to generate oil pressure corresponding to the amplitude of the detecting signal and the pad 1 is pressed against a torque receiving surface 2a of the disk circuit side. Thus, the vibration of the pad 1 in the tangential direction of the disk is stopped and the creak in the braking is not generated.

2. Description of the Related Art In a disc brake, a squeal phenomenon is generated due to various causes due to vibrations of a disc rotor (which is simply referred to as a disc in the present invention) and a friction member (pad) slidingly contacting the disc rotor during braking. May
Therefore, various measures have been taken to stop this squeal.

For example, Japanese Utility Model Laid-Open No. 2-134331 provides means for pressing and constraining a pad in the radial direction of a disk, and the means has a stronger force during braking than that during non-braking, specifically, a brake piston. A technique is disclosed in which the vibration of the pad is stopped by restraining the pad with a force proportional to the brake fluid pressure applied to the pad.

Further, in Japanese Patent Laid-Open No. 4-54324 and the like, vibration of a pad is detected by using a piezoelectric element, and based on the detection signal, the pad is excited by the piezoelectric element in a direction in which the brake vibration is cancelled. A damping device that suppresses squeal is shown.

On the other hand, the method of restraining the pad is easier to control than the former method because it eliminates the movement allowance of the vibration of the pad, but as shown in Japanese Utility Model Laid-Open No. 2-134331, the restraining force is reduced. It is not guaranteed that the vibration of the pad is stopped by the method of increasing the pressure in proportion to the brake fluid pressure.

The vibration of the pad does not increase in proportion to the brake fluid pressure, and a large vibration may occur even if the brake fluid pressure is low. Therefore, in this method, the restraint force may lose the force for moving the pad to cause vibration of the pad, and the squeal cannot be completely stopped. In addition to this, various squeal measures are being considered,
The reality is that none of them are truly satisfying even today.

In order to solve the above-mentioned problems, in the present invention, a device for detecting the vibration of a friction member which is in sliding contact with a disk, a means for restraining the friction member,
The restraint means control device is provided, and the friction member is restrained by the restraint means under the control of the control device by a force corresponding to the amplitude of the vibration detected by the vibration detection device.

It is considered that the squeal of the disc brake starts from the stick-slip vibration, which is a frictional vibration, and starts to vibrate, which then becomes a self-excited vibration to generate a squeal. The evidence is that, immediately before the squeal occurs, the friction member (pad) produces characteristic vibrations in the disk circumferential direction, which are considered to be stick-slip vibrations, and in the disk axial direction which is linked to it. In the present invention, this vibration is detected by the detection device, and the friction member is constrained by the force corresponding to the detected vibration by the constraining means. Therefore, the constraining force does not lose the force for moving the friction member, Before the vibration becomes self-excited vibration, it is securely pressed in and no squeaking occurs.

In the disc brake, the size of the restraint means that can be installed and the installation place are limited. Considering this, it is difficult to sufficiently bring out the squeal suppressing effect in the structure in which the friction member is pressed and restrained in the disc axial direction. That is, the optimum constraint point changes depending on the vibration mode of the squeal, and the position and area where the constraint can be performed are limited in the entire area of the friction member, and it is difficult to move the constraint point according to the squeal mode. Therefore, the most effective position cannot be restricted, and the vibration damping efficiency does not increase.

On the other hand, if the friction member is constrained by pressing the torque transmission surface in the tangential direction of the disk, the area of the torque transmission surface is small and the entire surface or almost the entire surface can be restricted. , Even if the squealing mode changes, the damping efficiency does not change, and it is possible to deal with squealing at any frequency.

Further, the two friction members placed on both sides of the disk do not necessarily vibrate in synchronism before a squeal is generated and a resonance state is generated, but vibration detection and restraint are individually performed for each friction member.

1 shows an example in which the present invention is applied to a floating disc brake. FIG. 1A is a view of the entire brake as viewed from the outer side in the disc axial direction. The pad (friction member) 1 has ears at both ends in the disc tangential direction as guide grooves provided in the torque member 2. It is loosely fitted and supported slidably in the disc axial direction. Also, caliper 7
Inserts a slide pin 8 (see FIG. 1B) into a pin hole (not shown) of the torque member to support the torque member 2 slidably in the disc axial direction. The brake piston (also not shown) inserted into the cylinder presses the inner pad against the disc, and the reaction force at that time causes the caliper 7 to slide to the inner side, causing the outer pawl of the caliper to slide the outer pad against the outer pad. It is structured to be pressed against.

The vibration detector 6 is connected to the control circuit 5. Further, the control circuit 5 is provided in the hydraulic pressure generator 4, and the hydraulic pressure generator 4 is provided in the cylinder 9 provided in the torque member 2.

In the exemplary disc brake having such a structure, when braking is performed, the vibration detector 6 provided on the disc feed-out side torque receiving surface portion at the time of normal rotation of the disc causes the pad 1 to vibrate in the disc tangential direction. Is detected, and the detection information flows to the control circuit 5. The control circuit 5 includes a circuit that determines whether or not the detected vibration requires squeal suppression control by checking the amplitude and frequency, and outputs a control execution signal from this circuit. Then, a control signal (current or voltage) flows from the control circuit 5 to the hydraulic pressure generator 4. The control signal is adjusted so as to increase the hydraulic pressure output from the hydraulic pressure generator 4 according to the amplitude of the detected vibration, and the hydraulic pressure controlled based on the signal is applied to one surface of the piston 3. Therefore, the piston 3 protrudes from the cylinder 9 and presses the torque transmitting surface on the disk advancing side at the time of normal rotation of the pad 1 toward the disk advancing side with a force according to the vibration amplitude, and the force causes the disk rotating of the pad 1 The output-side torque transmitting surface is pressed against the feed-out side torque receiving surface 2a to securely restrain the pad 1, and the restraint produces an excellent vibration damping action to prevent squeaking.

In the example brake, a piezoelectric element is used as the vibration detector 6, but an acceleration sensor, a strain gauge or the like may be used as the detector 6. The pad can also be restrained by using a piezoelectric element that utilizes an inverse piezoelectric effect instead of the piston 3 and pressing the pad with this element.

Furthermore, when the restraint control of each pad is performed independently, two sets of hydraulic pressure generators 4 are provided to individually control the hydraulic pressures supplied to the inner and outer cylinders 9, respectively.
The purpose can also be achieved by controlling the hydraulic pressure generation device 4 as one set and making the hydraulic pressure proportional to the one of the two detectors 6, 6 which has a larger amplitude. This configuration is advantageous in terms of cost because only one hydraulic pressure generator is required.

In addition to the above, the example brake has a structure corresponding to only the squeal at the time of normal rotation of the disk in consideration of the cost (since squeal is generally likely to occur when the vehicle is moving forward, this is sufficient), but vibration If the installation point of the detector 6 is shifted to a portion other than the torque receiving surface and the piston 3 and the cylinder 9 into which the piston 3 is inserted are provided in the left and right torque receiving portions, it is possible to cope with squeal when the disc is rotated in reverse.

The results of the confirmation test of the effect using the exemplified disc brake will be described below. The test was carried out on a dynamo tester using a vehicle equipped with an example brake. Whether or not the configuration of the present invention is effective for squealing cannot be accurately determined unless comparative evaluation is performed under braking conditions in which squealing is stably reproduced, so squeaking occurs almost without exception here. Conditions were selected such that the tire rotation speed was 30 km / h, the brake fluid pressure was 2 kgf / cm 2 , and the disk temperature was 80 ° C.

As in (a), a peak, which is the resonance frequency of the squeal, clearly appears in the detected sound. On the other hand, when the pad is restrained by a force corresponding to the vibration amplitude to suppress the vibration, as shown in FIG. 2B, the brake noise is small and the detected sound reaches the same level as that when the tire is idling.
