Abstract

PURPOSE: To bring about powerful and quiet braking and facilitate easy replacement of pads by letting contact means include a yoke constructed at the rear side in the direction of the disc running between calipers, and by providing fastening means at the calipers with pins surrounded by the yoke. CONSTITUTION: Each pad 5 has the contact means 13 adjoining the fastening means 14. The contact means has the yoke 15 at the rear end of the plate 6 in the arrowed direction G of the pad 5. The fastening means sits on the caliper 2, and has a pin 17 provided encircled by the yoke 15. In forward running braking, the pad 5 is held by a rear wall 15b contacting a rear line 18b of a cylindrical head 18, and continued strong braking does not cause vibration and shaking. In backward running braking, the pad 5 is held by a front wall contacting the front line 18a of the cylindrical head 18, and continued strong braking does not cause vibration and shaking. The pad can easily be replaced by removing the pad 5 from a spring 12 and a pin 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc brake used in automobiles and the like.

[0002]

Disc brakes are known as having substantially square brake pads, the front and rear ends of which form an arch. Both ends of this brake pad are placed so as to abut the leading and trailing walls of each pad seat, or preferably along the generatrix of the cylindrical head of each screw facing the interior of said seat. It is preferably arranged. This is the car moving forward,
Alternatively, it depends on applying the brake when the vehicle is moving backward.

This construction is useful in many respects, such as rapid pad replacement. However, when the brake is applied for a long time and strongly, this is not enough and vibration and noise are likely to occur.

Some disc brakes are also known in which each brake pad is provided with two hooks. One of the hooks protrudes from the rear end and the other protrudes from the front end, and when the car is braked while the car is moving forward or backward, it connects to the pins on the brake caliper. ..

[0005]

When the above-mentioned two hooks are used, vibration and rattling can be eliminated, but replacement of the pad is very difficult. When you replace the pads,
The caliper body loosens and rotates vertically around the pin on the shaft, causing it to flip over.

SUMMARY OF THE INVENTION The technical problem addressed by the present invention is therefore to provide a disc brake having a construction and performance characteristics which overcomes the aforementioned drawbacks associated with the prior art.

Further objects and effects of the present invention will be described in more detail in the embodiments.

Embodiments of the present invention will now be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a disc brake used in a fixed caliper type automobile or the like according to an embodiment of the present invention.

The disc brake 1 includes a brake caliper 2 (hereinafter simply referred to as a caliper) and a brake caliper.
The disk 3 is provided.

The caliper 2 is provided for connecting from the suspension of the automobile to the shaft by screws 2a and 2b. The brake disc 3 has an annular braking strip 4 and serves to stop the wheels of the motor vehicle.

The caliper 2 is provided so as to straddle a braking strip 4 which runs through the caliper 2 when the vehicle is driven in a forward direction, that is, a predetermined direction indicated by an arrow G in FIG. ..

The traveling direction described above is opposite when the vehicle moves backward.

The two pads 5 comprise a steel plate 6 holding a friction lining 7 and are fixed to the caliper 2 in a seat 8. This seat 8 is open in the radial direction of the brake disc 3 going outwards through the gap 9. Two hydraulic cylinders 5a and 5b are arranged to move on each pad 5.

More specifically, the pad 5 is fixed to the caliper 2 by a pin 10 which penetrates an elongated hole 11 formed in the plate 6. The spring 12 provided on the caliper 2 when the brake is not operating.
Always urges the pin 10 and the pad 5 to prevent rattling.

The plate 6 of each pad 5 has a leading end 6a and a trailing end 6b in the direction of arrow G, which indicates the direction in which the braking strip 4 penetrates the caliper 2. In this way, when moving through the caliper 2 in the forward gear state, the braking strip 4 firstly moves toward the trailing end 6b.
Then, the leading edge 6a is faced.

Each pad 5 comprises an abutment means 13 adjacent to a locking means 14 provided on the caliper 2 under the braking force exerted in the tangential direction of the braking strip 4 by being braked.

In the disc brake of the present invention, the contact means 13 is provided with a yoke 15 at the trailing end of the plate 6 in the direction of the arrow G of each pad 5.

More specifically, the yoke 15 has a leading wall 15a and a trailing wall 15b which are leading and trailing in the direction of the arrow G while facing each other. Inner space 16
Is provided between the leading wall 15a and the trailing wall 15b and opens toward the outside of the circumference of the braking strip 4.

It has to be noted here that the leading wall 15a lies substantially on the same straight line as the trailing end 6b of the plate 6.

The locking means 14 for a disc brake according to the present application has a pin 17 provided on the caliper 2 and surrounded by a yoke 15. In other words, the pin 17 is the front wall 15 of the yoke 15.
It is provided in the inner space 16 between the a and the trailing wall 15b.

The pin 17 can more preferably be embodied as a cylindrical head 18 of a screw 9 which penetrates the caliper 2.

In operation, when the brake is applied during traveling in the forward direction, the pad 5 is held by the trailing wall 15b which abuts the rear line 18b of the cylindrical head 18. Therefore, even when the brake is applied strongly for a long time, the entire pad is exposed to the tension, and the vibration or rattling does not occur.

Further, when traveling in the reverse direction, the pad 5
Is held by the leading wall 15a that abuts the front line 18a of the cylindrical head 18, and the entire pad 5 is exposed to the tension. No vibration or rattling will occur.

Brake pad replacement is accomplished by simply removing the pads from spring 12 and pin 10. That is, the pad 5 is rotated around the cylindrical head 18 in the direction of arrow F so as to move to the position shown by the broken line, and passes through the gap 9 while the cylindrical head 18 is removed from the yoke 15. Be removed.

The greatest advantage of the disc brake of the present invention is that strong and quiet braking operation can be achieved as well as easy replacement of the brake pads.

The disc brakes described above can be modified in many ways to meet the attendant specific requirements without departing from the scope of the claims.

[0031]

As described above, according to the disc brake of the present invention, strong and quiet braking without rattling is possible, and at the same time, the brake pad can be easily replaced. obtain.
