故障時でも車両の安定性を保証し、かつ法的に要求され
たブレーキ管路を得るためにはやはり圧力制限器若しく
は減圧器がブレーキ機構に備えられる。In many motor vehicles equipped with hydraulic brake systems, a pressure limiter or pressure reducer is arranged between the wheel brake cylinder of the rear axle and the master cylinder in order to prevent overbraking of the rear axle and thus skidding of the vehicle. For this purpose, the brake circuit is configured such that locking of the front wheels occurs before locking of the rear wheels. This is achieved by a pressure reducer or pressure limiter located within the brake system. Cars with anti-lock control devices have ABS
It is not necessary to have a pressure limiter in order to ensure the stability of the vehicle when functioning, but it is necessary to ensure the stability of the vehicle even in the event of a failure of the anti-lock control device, and the legally required brake line In order to obtain this, a pressure limiter or pressure reducer is also provided in the brake mechanism.
しかし、公知の圧力制限器若しくは減圧器の組込みは、
特にこれらがアンチロック制御装置の故障時にだけ使用
されることを考慮すれば著しく不経済である。However, the incorporation of known pressure limiters or pressure reducers
This is extremely wasteful, especially considering that they are used only in the event of a failure of the anti-lock control device.
［発明の利点１
請求項１に記載のブレーキ装置の利点とするところは、
圧力制限器が簡単に構成されると共に、ＡＢＳ機能時に
制御回路になんの影響も及ぼさないことにある。[Advantage 1 of the invention The advantage of the brake device according to claim 1 is that
The pressure limiter is simple in construction and does not have any influence on the control circuit during the ABS function.

ねじ込まれることもでき、又はフランジ弁として形成さ
れることもできる。それゆえ、本圧力制限器は簡単に自
動車に取付けることができる。The release of the pressure limiting function takes place directly by means of the integrated 2/2-way magnetic valve. Known pre-connected valves with additional valve elements are not provided according to the invention. The pressure limiter is therefore simple to construct. In this case, the pressure limiter is also designed as a screw-in valve, but it can also be screwed coaxially into the brake line as a line valve, or it can also be designed as a flange valve. Therefore, the present pressure limiter can be easily installed in a motor vehicle.

力制限器はＡＢＳ機能、例えば圧力保持又は減圧を行わ
ない。The pressure limiter is used as an emergency valve, which does not act on the brake circuit when A or B S is activated during normal operation;
Acts as a pressure limiting valve only when BS fails. When ABS is activated, this valve is in the inactive position. Therefore, this pressure limiter does not perform an ABS function, such as pressure holding or pressure reduction.
この圧力制限器は、後車輪ブレーキ圧を制御するアンチ
ロック制御装置を備えた自動車の公知圧力制限器若しく
は減圧器の代わりを務める。This pressure limiter replaces the known pressure limiters or pressure reducers in motor vehicles equipped with anti-lock control systems that control the rear wheel brake pressure.

ーキ圧が一定の値に制限される。圧力制限器は減圧器と
して形成されることができる（請求項１１〜１３）。こ
の場合には、切換え圧の導入以後、ブレーキ圧が一定の
７アクタだけ減少する。When the magnetic valve is activated in the event of an ABS failure, the brake pressure is regularly limited to a certain value. The pressure limiter can be designed as a pressure reducer (claims 11 to 13). In this case, after the introduction of the switching pressure, the brake pressure decreases by a constant 7 actors.
圧力制限機能を解除できることによって、部分制動範囲
内での後車輪ブレーキ圧の増大による均一なライニング
摩耗が得られ、その場合、全制動でのＡＢＳ故障時の車
両安定性が維持される。The ability to release the pressure limiting function results in uniform lining wear due to an increase in rear wheel brake pressure within the partial braking range, in which case vehicle stability is maintained in the event of an ABS failure with full braking.

る。In this configuration, instead of a pressure limitation, a pressure reduction takes place in the wheel brake cylinder 14 of the rear axle. This pressure reduction is caused by the brake fluid pressure flowing from the left side in the drawing and acting on the left end surface 19 of the piston 20.
0 moves to the right against the piston spring 4 and closes the ball valve. At the same time, however, the right-hand end face 21 of the piston 20 is likewise loaded with brake pressure by the brake fluid passing through the inlet 18, causing the piston 20 to move to the left and thereby opening the ball valve 7 again. Due to this mutually opposite movement of the pistons 20, the pressure supplied by the master cylinder 12 is reduced by a certain factor and is supplied as brake pressure to the wheel brake cylinders 14. In that case, the outlet pressure decreases compared to the inlet pressure depending on the area ratio of the end face 19.21 of the piston 20.
