定をもってアウトプットロッド３に踏力を伝えている。The operation of such a negative pressure booster is based on the input rod 1.
1) Separate the popular chamber B from the negative chamber A by operating the valve based on the zero base, and introduce outside air into the atmospheric chamber B. The pedal force is transmitted to the output rod 3 by pressing the put rod 3 and also by directly suppressing the reaction disk 2 by the input rod 1, determining the J ratio of J to the reaction disk 2. .

いう問題点があった。However, in such a conventional negative pressure force device, the contact area of the implant 1-rod 1 and the power piston 4 with respect to the rear axis 31-disk 3, and the reaction of the outgut 1-rod 3 are limited. Since the contact area against the disc 2 is always constant with respect to the pedal force, the second
As shown in the graph in the figure, the multiplication ratio is constant, which causes the problem that the brakes are too effective when lightly stepping on the brakes.

A rear axicon disc consisting of an inner disc and an outer disc with a large contact area is used 1. Under heavy 211 force, the inner disc contacts JJ and the boost ratio is low, and with strong pedaling force, the inner disc is in contact with JJ. The outer disc's power output was increased by the deformation of the '-r frame (boosting ratio was increased).
以下、本発明の実施例を図面に基づいて説明”する。Embodiments of the present invention will be described below with reference to the drawings.

ている。First of all, to explain the structure, in the center between the inlets 1 to 11 and 10 and the outboards 1 to 14, there is a disk-shaped inner disk 18 with a size that does not come into contact with the power screws 1 to 4. This inner disk 1
An annular outer disk 20 is provided on the outside of the power piston 4 with a gap 19 therebetween.

１で作動づる。The operation of the embodiment shown in FIG. 3 is as follows: First, when the pedal force is small, the inner disk 18 provided between the output 1'' rod 14 is compressed by the forward movement of the input button 1 and the rod 10, and the inner disk 18 is compressed by the power piston. Since the force 4 is not acting, the pedaling force of the input rods 1 to 10 is directly transmitted to the output rod 14, and the output rod 14 is operated with a force ratio of 1.

Fill in 9, inner disk 18 and outer disk 2
0 is integrated into the input rod 10 and power screw 1
The force of ~4 is transmitted to the output 14 to increase the force ratio of 18. In other words, as shown in the graph of Figure 4, when the pedal force is small, the boost ratio is 1. ~

４つる。FIG. 5 is a cross section 1.52 showing another embodiment of the present invention in which a part of the inner disk 18 that is similar to the embodiment of FIG. 3 is brought into contact with the power screws 1 to 4. This is a clear drawing, and a part of the inner disk 18 has a bar 1 and no piston 4.
Due to the force acting on j, the boost ratio when the pedal force is ILL can be over 1, and as a result, the pedal horn is small (I+, 'iσ ) (Of course, it is possible to make the 74 force ratio higher than that of the embodiment of FIG. 3 shown in the graph of FIG. 4, and even in the embodiment of FIG.
If the pedaling force increases until the deformation occurs to fill one gap with the outer disc 2o, then i;b switches to the B horn ratio.

出來る。Next, to explain the present invention in detail, (to determine the H'5 force ratio, the axis 1 disc is formed of an inner disc and an outer disc whose abutting surface is set back. Therefore, when the pedal force is low, only the inner disc is used. Since the contact area with the output rod is small, a low boost ratio is achieved, preventing the brake from becoming too effective even if the brake pedal is depressed, and allowing fine adjustment of the braking force. As a result, braking feeling can be greatly improved.
