本発明は主としてオートバイその他の自動２輪車に使用

かるものでは特に２輪車が大型の場合、これに急制動を
与えることが困難である。Conventionally, in this type of device, when the mask cylinder is operated in conjunction with the operation of the brake lever, brake pedal, or other brake operator, pressure oil is guided into the caliper cylinder at the tip of the caliper body, and the pressure oil is drawn to the outside of the brake disc. There is a known type in which a pair of left and right pads are pushed together and actuated to close each other, but in such a type, the pressure of the pressure oil, and therefore the braking force from the pads, is not applied to the brake operator. Generally, the formula is approximately proportional to the operating force applied to the vehicle, and it is difficult to apply sudden braking to a two-wheeled vehicle, especially if the vehicle is large.
即ちこの場合ブレーキ操作子に大きな操作力を相当の長
時間継続して与えるを要し、これは必ずしも容易ではな
い。That is, in this case, it is necessary to continuously apply a large operating force to the brake operator for a considerable period of time, which is not necessarily easy.

A disc brake device in which a caliper body having a pair of left and right pads on both sides of a brake disc, which are pushed by pressure oil in the cylinder and actuated to close each other, is mounted on a wheel having the disc. The caliper body is swingably supported on the axis of the wheel, and a torque detection device comprising a torque rod and a torque cylinder fitted to a piston at the tip of the rod is provided between the caliper body and the vehicle body frame. The present invention is characterized in that a pressure chamber in the torque cylinder of the detector is communicated with a pressure chamber having a servo piston formed on the back surface of the pressure piston of the mask cylinder.
本発明実施の１例を別紙図面に付説明する。An example of implementing the present invention will be explained with reference to the attached drawings.

動されるようにした。The main body 5 has a caliper cylinder 6 therein as is well known.
According to the operation of the mask cylinder 8 in conjunction with the operation of the brake lever, brake pedal, or other brake operator 7, pressure oil is generated in the cylinder 8, and this is pumped into the caliper cylinder 6 via the brake hose 9. The above-mentioned pair of pads were pushed by this and were actuated toward each other in the closing direction.

This system automatically increases the pressure of the above-mentioned pressure oil and is constructed as follows.

１８内にこれに応じた油圧が発生されるようにした。That is, the caliper body 5 described above is attached to the shaft 1 of the wheel 2 described above.
4 so that it can swing freely, so that when the pad closes as described above, rotational torque accompanying the rotation of the brake disc 4 is applied to the pad, and furthermore, the tip of the main body 5 A torque detector 19 consisting of a torque rod 16 that can move freely forward against a spring 15 and a torque cylinder 18 that fits into a piston 17 at the tip of the torque rod 16 is interposed between the body frame 1 and the above-mentioned body frame 1. According to the rotational torque described above, the rod 16 moves forward in accordance with this, and a corresponding hydraulic pressure is generated in the cylinder 18.
これを換言すればキャリパ本体５に作用する車輪２のト
ルクがこれに対応する油圧として取出されるようにした
。In other words, the torque of the wheel 2 acting on the caliper body 5 is taken out as the corresponding hydraulic pressure.

昇を生じさせるべく作用するようにした。This oil pressure is then applied to the servo piston 20 to increase the pressure in the pressure oil in the caliper cylinder 6, and in the illustrated example, the servo piston 20 is applied to the pressure piston 10 in the mask cylinder 8. Prepare the pressure chamber 21 on the back side facing this, and connect the pressure chamber 21 on the back side with the hose 2.
The hydraulic pressure is communicated with the inside of the torque cylinder 18 through the piston 20, and acts to press the piston 10 through the piston 20 to cause a pressure increase in the pressure oil in the hydraulic chamber 11 in front of the piston 10. I decided to do so.

Almost the same braking is applied even when the vehicle is in use.

与えられる。To explain its operation, when the brake operator 7 is operated to operate the mask cylinder 8, pressure oil is introduced into the caliper cylinder 6, and the pair of left and right pads mutually operate toward the closing side. The fact that braking is applied to the wheel 2 is not particularly different from the conventional one, but according to this operation, the caliper main body 5 is engaged with the brake disc 4, and the rotational torque accompanying the rotation of the caliper is applied, and the torque is detected. This oil pressure acts on the servo piston 20 to push the pressure piston 10 in the mask cylinder 8 forward, thus reducing the pressure oil in the hydraulic chamber 11 in front of it, and thus The pressure oil in the caliper cylinder 6 is given a corresponding pressure increase.
これを換言すればキャリパ本体５に作用するトルクが制
動力を増大すべく利用され、かくてブレーキ操作子１に
作用する操作力は比較的少さくて足りる。In other words, the torque acting on the caliper body 5 is used to increase the braking force, and thus the operating force acting on the brake operator 1 only needs to be relatively small.

効果を有する。As described above, according to the present invention, the caliper main body is rotated along with the brake disc, and the rotational torque is detected as hydraulic pressure and is transferred to a pressure chamber having a servo piston provided in a mask cylinder. Since the operating force of the brake operating element is increased by this detected torque and a large braking action can be obtained, it is possible to provide good sudden braking with a relatively small operating force.
Moreover, since the detector is installed separately from the caliper body, the installation of the detector does not increase the unsprung weight of the vehicle, which impairs handling stability. It has the advantage of being easily attachable to the main body.
