欧州特許第１１７６０７５号明細書European Patent No. 1176075

しかしながら、上記のような３つの液圧制御回路を有するブレーキ装置においてはその構造上のコストが高くなってしまうという問題があった。   However, the brake device having the three hydraulic pressure control circuits as described above has a problem in that its structural cost increases.

本発明は上記問題に鑑みてなされたもので、その目的とする処は、１つのマスタシリンダの操作により前輪のホイールブレーキ及び後輪のホイールブレーキに生じるブレーキ液圧を制御することができる、構造が簡単で動作信頼性の高いブレーキ装置を提供することにある。   The present invention has been made in view of the above-described problems, and its object is to control the brake fluid pressure generated in the front wheel brake and the rear wheel brake by operating one master cylinder. Is to provide a brake device that is simple and highly reliable in operation.

上記目的は、請求項１記載の特徴を有するブレーキ装置により達成される。   The object is achieved by a brake device having the features of claim 1.

本発明によれば、制御性能に関して決定的な損失を甘受することなく流入側切換弁及び流出側切換弁の個数をそれぞれ２つに削減することができるとともに、コストを削減することもできる。   According to the present invention, it is possible to reduce the number of inflow side switching valves and outflow side switching valves to two without accepting a decisive loss in terms of control performance, and it is also possible to reduce costs.

本発明の他の特徴及び利点は、従属請求項及び下記の実施の形態に記載されている。   Other features and advantages of the invention are set forth in the dependent claims and in the following embodiments.

以下に本発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

図１には本発明の基本的な構成を備えた自動二輪車用ブレーキ装置の液圧回路が示されている。当該ブレーキ装置は液圧で作動する前輪ブレーキ回路４（第１のブレーキ回路）及び後輪ブレーキ回路１０（第２のブレーキ回路）から成り、これら前輪ブレーキ回路４及び後輪ブレーキ回路１０は、手で操作されるマスタシリンダ７と、足で操作されるマスタシリンダ１３にそれぞれ接続されている。   FIG. 1 shows a hydraulic circuit of a motorcycle brake device having the basic configuration of the present invention. The brake device includes a front wheel brake circuit 4 (first brake circuit) and a rear wheel brake circuit 10 (second brake circuit) that are operated by hydraulic pressure. The front wheel brake circuit 4 and the rear wheel brake circuit 10 are configured by hand. Are connected to a master cylinder 7 operated by a foot and a master cylinder 13 operated by a foot.

又、前輪ブレーキ回路４及び後輪ブレーキ回路１０それぞれには電磁的に操作される流入側切換弁６及び流出側切換弁１２がスリップ制御用に設けられており、流入側切換弁６が常開型として形成されて両ブレーキ回路４，１０の液圧通路内に設けられる一方、流出側切換弁１２は常閉型として形成されて両ブレーキ回路４，１０それぞれの還流通路１５に設けられている。   Each of the front wheel brake circuit 4 and the rear wheel brake circuit 10 is provided with an inflow side switching valve 6 and an outflow side switching valve 12 that are electromagnetically operated for slip control, and the inflow side switching valve 6 is normally open. While being formed as a mold and provided in the hydraulic pressure passages of both brake circuits 4 and 10, the outflow side switching valve 12 is formed as a normally closed type and is provided in the return passages 15 of both brake circuits 4 and 10. .

ここで、上記各還流通路１５は、各ブレーキ回路４，１０に設けられた還流ポンプ９の流入パスと前輪のホイールブレーキ５及び後輪のホイールブレーキ１４をそれぞれ接続する。   Here, each of the return passages 15 connects an inflow path of the return pump 9 provided in each of the brake circuits 4 and 10 to a front wheel brake 5 and a rear wheel brake 14.

而して、各還流ポンプ９はその高圧側で両ブレーキ回路４，１０それぞれの液圧通路１８に接続されており、スリップ制御時に、前輪のホイールブレーキ５及び後輪のホイールブレーキ１４から流出するブレーキフルードの必要十分量を液圧通路１８に還流させることができる。尚、各還流ポンプ９のポンプピストンは共通のモータ２により駆動されている。   Thus, each return pump 9 is connected to the hydraulic pressure passages 18 of the brake circuits 4 and 10 on the high pressure side, and flows out from the front wheel brake 5 and the rear wheel brake 14 during slip control. A necessary and sufficient amount of brake fluid can be returned to the hydraulic passage 18. Note that the pump piston of each reflux pump 9 is driven by a common motor 2.

又、両ブレーキ回路４，１０を、その構造により共に、或いは互いに独立して作動させることができ、例えば、前輪ブレーキ回路４に接続されたマスタシリンダ７を手で操作する場合、スリップなしのブレーキング中、或いはスリップ制御されたブレーキング中において前輪のホイールブレーキ５にのみブレーキ圧力上昇或いはブレーキ圧力制御が生じる。   Further, both brake circuits 4 and 10 can be operated together or independently of each other. For example, when the master cylinder 7 connected to the front wheel brake circuit 4 is operated by hand, the brake without slip During braking, or during braking under slip control, only the front wheel brake 5 has a brake pressure increase or brake pressure control.

一方、後輪ブレーキ回路１０に接続されたマスタシリンダ１３を操作した場合には、スリップなしのブレーキング中、或いはスリップ制御されたブレーキング中において後輪のホイールブレーキ１４のみにブレーキ圧力上昇或いはブレーキ圧力制御が生じるわけではなく、本実施の形態においては前輪ブレーキ回路４と後輪ブレーキ回路１０の間にこれらを連通させる液圧接続通路１が介装されているため、前輪のホイールブレーキ５にもブレーキ圧力上昇或いはブレーキ圧力制御が生じる。   On the other hand, when the master cylinder 13 connected to the rear wheel brake circuit 10 is operated, the brake pressure is increased or braked only to the wheel brake 14 of the rear wheel during braking without slip or braking with slip control. In the present embodiment, the hydraulic pressure connection passage 1 is provided between the front wheel brake circuit 4 and the rear wheel brake circuit 10, so that the wheel brake 5 of the front wheel is provided with the pressure control. In this case, brake pressure rise or brake pressure control occurs.

ところで、本発明によれば、特許文献１に開示されているような３つの通路を有するブレーキ装置を２つの通路とし、制御性能に関して決定的な損失を甘受することなく流入側切換弁６及び流出側切換弁１２の個数をそれぞれ２つに削減することができるとともに、コストを削減することもできる。   By the way, according to the present invention, the brake device having three passages as disclosed in Patent Document 1 is used as two passages, and the inflow side switching valve 6 and the outflow are not accepted without decisive loss regarding control performance. The number of side switching valves 12 can be reduced to two, and the cost can be reduced.

又、前輪のホイールブレーキ５における後輪ブレーキ回路１０によるブレーキ圧力の発生及び制御が行われるように、液圧接続通路１がその片側で後輪ブレーキ回路１０に設けられた流入側切換弁６に接続されている。   Further, the hydraulic pressure connection passage 1 is connected to the inflow side switching valve 6 provided in the rear wheel brake circuit 10 on one side so that the brake pressure is generated and controlled by the rear wheel brake circuit 10 in the wheel brake 5 of the front wheel. It is connected.

そして、図１に示すように、液圧接続通路１は、後輪ブレーキ回路１０の流入側切換弁６、流出側切換弁１２及び後輪のホイールブレーキ１４を接続する液圧通路から分岐して前輪ブレーキ回路４の前輪のホイールブレーキ５まで延設されている。   As shown in FIG. 1, the hydraulic pressure connection passage 1 branches off from the hydraulic pressure passage connecting the inflow side switching valve 6, the outflow side switching valve 12, and the rear wheel wheel brake 14 of the rear wheel brake circuit 10. The front wheel brake circuit 4 extends to the front wheel brake 5.

又、図１に更に示すように、ディスクブレーキとして形成された前輪のホイールブレーキ５は互いに離間して配置された第１のブレーキシリンダ１９及び第２のブレーキシリンダ２０を備えており、第１のブレーキシリンダ１９は前輪ブレーキ回路４のみと接続されている一方、第２のブレーキシリンダ２０は液圧接続通路１を介して後輪ブレーキ回路１０のみと接続されている。   As further shown in FIG. 1, the front wheel brake 5 formed as a disc brake includes a first brake cylinder 19 and a second brake cylinder 20 that are spaced apart from each other. The brake cylinder 19 is connected only to the front wheel brake circuit 4, while the second brake cylinder 20 is connected to only the rear wheel brake circuit 10 via the hydraulic pressure connection passage 1.

従って、各ブレーキ回路４，１０で発生するブレーキ圧力をそれぞれ独立して前輪のホイールブレーキ５へ供給することができる。   Therefore, the brake pressure generated in each of the brake circuits 4 and 10 can be independently supplied to the wheel brake 5 of the front wheel.

又、キャリパにおいて互いに離間して配置された第１及び第２のブレーキシリンダ１９，２０を備えたディスクブレーキの他の形態として、前輪のホイールブレーキ５を多板ディスクブレーキとすることも可能であり、この際、前輪のホイールブレーキ５を２つのディスクブレーキで構成するのが好ましい。このように構成することで、大きなブレーキトルクを伝達することが可能である以外に、例えば、片方のディスクブレーキを前輪ブレーキ回路４に接続するとともに、もう一方のディスクブレーキを液圧接続通路１を介して後輪ブレーキ回路１０に接続し、必要に応じて各ブレーキシリンダ１９，２０へのブレーキ液圧を相違させることも可能である。   Further, as another form of the disc brake having the first and second brake cylinders 19 and 20 arranged apart from each other in the caliper, the front wheel brake 5 can be a multi-disc disc brake. In this case, it is preferable that the wheel brake 5 of the front wheel is constituted by two disc brakes. With this configuration, in addition to being able to transmit a large brake torque, for example, one disc brake is connected to the front wheel brake circuit 4 and the other disc brake is connected to the hydraulic pressure connection passage 1. It is also possible to connect the brake fluid pressure to the brake cylinders 19 and 20 as necessary, by connecting to the rear wheel brake circuit 10 via the rear wheel brake circuit 10.

ところで、後輪ブレーキ回路１０に接続されたマスタシリンダ１３を操作すると、”セレクトロー”に基づくアンチロック制御によるスリップ制御ブレーキングが両ホイールブレーキ５，１４に対してなされる。即ち、前輪及び後輪のうち少ないロックが生じている車輪により両ホイールブレーキ５，１４に対するブレーキ液圧が決定される。   By the way, when the master cylinder 13 connected to the rear wheel brake circuit 10 is operated, slip control braking by anti-lock control based on “select low” is performed for both wheel brakes 5, 14. That is, the brake fluid pressure for both wheel brakes 5 and 14 is determined by the wheel in which a small amount of lock is generated among the front wheels and the rear wheels.

更に、前輪及び後輪のうちどちらかがロックしてスリップ状態に陥ると、直ちに両ブレーキ回路４，１０の少なくともどちらかで高められたブレーキ液圧を流入側切換弁６及び流出側切換弁１２により減少させるために、各車輪の速度変化が電子制御装置８により検出・評価される。   Further, when one of the front wheels and the rear wheels is locked and falls into a slip state, the brake fluid pressure increased by at least one of the brake circuits 4 and 10 is immediately increased to the inflow side switching valve 6 and the outflow side switching valve 12. Therefore, the speed change of each wheel is detected and evaluated by the electronic control unit 8.

而して、前輪ブレーキ回路４に接続されたマスタシリンダ７及び後輪ブレーキ回路１０に接続されたマスタシリンダ１３を同時に操作するような場合には、前輪用のマスタシリンダ７で制動される前輪の回転数変化或いは速度変化が前輪ブレーキ回路４に一義的に割り当てられる。   Thus, when the master cylinder 7 connected to the front wheel brake circuit 4 and the master cylinder 13 connected to the rear wheel brake circuit 10 are operated simultaneously, the front wheels braked by the front wheel master cylinder 7 are controlled. A change in rotational speed or a change in speed is uniquely assigned to the front wheel brake circuit 4.

そのため、前輪ブレーキ回路４に接続されたマスタシリンダ７の操作が圧力センサ２１により検出される。そして、各ブレーキ回路４，１０において必要十分なアンチロック制御がなされるよう電子制御装置８によって流入側切換弁６及び流出側切換弁１２を電子的に操作するために、圧力センサ２１からの信号及び各車輪の車輪回転数センサ１７により検出された車輪回転状態に基づき電子制御装置８が後輪ブレーキ回路１０におけるブレーキ液圧を算出する。   Therefore, the operation of the master cylinder 7 connected to the front wheel brake circuit 4 is detected by the pressure sensor 21. A signal from the pressure sensor 21 is used to electronically operate the inflow side switching valve 6 and the outflow side switching valve 12 by the electronic control unit 8 so that necessary and sufficient antilock control is performed in each brake circuit 4, 10. The electronic control unit 8 calculates the brake fluid pressure in the rear wheel brake circuit 10 based on the wheel rotation state detected by the wheel rotation number sensor 17 of each wheel.

尚、上述の例とは逆に、後輪のホイールブレーキ１４を前輪のホイールブレーキ５の操作に依存して動作させ、液圧接続通路１を前輪ブレーキ回路４から後輪のホイールブレーキ１４における２つの互いに離間して配置されたブレーキシリンダの何れかに接続させても良い。   Contrary to the above-described example, the rear wheel brake 14 is operated depending on the operation of the front wheel brake 5, and the hydraulic connection passage 1 is moved from the front wheel brake circuit 4 to the rear wheel brake 14. It may be connected to any one of the two brake cylinders spaced apart from each other.

更に、後輪ブレーキ用のマスタシリンダ１３を足ではなく手で操作できるよう構成し、この後輪ブレーキ用のマスタシリンダ１３を前輪ブレーキ用のマスタシリンダ７と同様にハンドルバーに設け、手で操作するブレーキレバーとして構成することもできる。又、前輪ブレーキ用のマスタシリンダ７を足で操作するものとすることもできる。   Further, the rear-wheel brake master cylinder 13 can be operated by hand instead of the foot, and the rear-wheel brake master cylinder 13 is provided on the handlebar in the same manner as the front-wheel brake master cylinder 7 and is operated by hand. It can also be configured as a brake lever. It is also possible to operate the master cylinder 7 for the front wheel brake with a foot.

ところで、図１に示すように、常開型の流入側切換弁６及び常閉型の流出側切換弁１２は、それぞれ電磁的に操作される２ポート２位置型切換弁として形成され、通常はバネ付勢されてそれぞれの所定位置（開位置或いは閉位置）に保持されている。   By the way, as shown in FIG. 1, the normally open type inflow side switching valve 6 and the normally closed type outflow side switching valve 12 are each formed as a two-port two-position switching valve that is electromagnetically operated. Each spring is biased and held at a predetermined position (open position or closed position).

又、図１には明確に示してはいないが、上記従来技術のように遅延バルブを後輪ブレーキ回路１０、即ち図１における液圧接続通路１と後輪ブレーキ回路１０の接続点と後輪のホイールブレーキ１４との間に設けても良い。   Although not clearly shown in FIG. 1, the delay valve is connected to the rear wheel brake circuit 10, that is, the connection point between the hydraulic pressure connecting passage 1 and the rear wheel brake circuit 10 in FIG. It may be provided between the wheel brake 14.

而して、図１に抽象的に示してある電子制御装置８は、前輪ブレーキ回路４及び後輪ブレーキ回路１０を備えて一体的に構成されたブレーキユニット１１の統合された１つの部材を構成しており、ブレーキユニット１１内に配設された流入側切換弁６及び流出側切換弁１２に電気的に接続されている。   Thus, the electronic control device 8 shown abstractly in FIG. 1 constitutes one integrated member of the brake unit 11 that is integrally formed with the front wheel brake circuit 4 and the rear wheel brake circuit 10. The inflow side switching valve 6 and the outflow side switching valve 12 disposed in the brake unit 11 are electrically connected.

従って、ブレーキユニット１１をコンパクト化して自動二輪車の車体（フレーム）のバッテリ近傍に設けることができる。   Therefore, the brake unit 11 can be made compact and provided near the battery of the vehicle body (frame) of the motorcycle.

次に、上記構成を有するブレーキ装置のスリップ制御時の作用について説明する。   Next, the effect | action at the time of slip control of the brake device which has the said structure is demonstrated.

先ず、車輪回転数センサ１７からの信号に基づき電子制御装置１８が処理・評価して前輪或いは後輪のロック傾向が認識され、電子制御装置８からの信号に基づいて前輪ブレーキ回路４或いは後輪ブレーキ回路１０に設けられた流入側切換弁６が励磁されて閉鎖される。従って、前輪ブレーキ回路４或いは後輪ブレーキ回路１０での更なる増圧が回避される。   First, the electronic control unit 18 processes and evaluates based on the signal from the wheel rotational speed sensor 17 to recognize the tendency of the front wheel or the rear wheel to be locked. The inflow side switching valve 6 provided in the brake circuit 10 is excited and closed. Therefore, further pressure increase in the front wheel brake circuit 4 or the rear wheel brake circuit 10 is avoided.

ここで、ロック傾向を軽減すべく前輪ブレーキ回路４或いは後輪ブレーキ回路１０での更なる減圧が必要な場合には、低圧アキュームレータ１６に接続された流出側切換弁１２が開放される。しかし、この流出側切換弁１２は、ロック傾向を生じていた車輪の加速度が再び所定加速度以上となれば再び閉鎖される。そして、上記減圧時においても流入側切換弁６は閉鎖位置に維持され、マスタシリンダからの液圧が前輪ブレーキ回路４或いは後輪ブレーキ回路１０に伝達されないようになっている。   Here, when further pressure reduction is required in the front wheel brake circuit 4 or the rear wheel brake circuit 10 to reduce the locking tendency, the outflow side switching valve 12 connected to the low pressure accumulator 16 is opened. However, the outflow side switching valve 12 is closed again when the acceleration of the wheel that has caused the locking tendency again becomes equal to or higher than the predetermined acceleration. The inflow side switching valve 6 is maintained at the closed position even during the pressure reduction, so that the hydraulic pressure from the master cylinder is not transmitted to the front wheel brake circuit 4 or the rear wheel brake circuit 10.

そして、ロック傾向が軽減されたと判断されると、電子制御装置１８からの信号に基づき流入側切換弁６が時間を制限して開放され、前輪ブレーキ回路４或いは後輪ブレーキ回路１０での増圧がなされる。尚、増圧に必要なブレーキフルード量は還流ポンプ９により供給される。   When it is determined that the locking tendency has been reduced, the inflow side switching valve 6 is opened for a limited time based on a signal from the electronic control unit 18, and the pressure in the front wheel brake circuit 4 or the rear wheel brake circuit 10 is increased. Is made. The amount of brake fluid necessary for pressure increase is supplied by the reflux pump 9.
