It includes associated control devices t, g of valve type. In the first position of the control lever , such a controller controls the fluid source via the conduit and associated passageway 70. key valve 7/, and located between the parking brake piston OD and the third piston OD. is transmitted under pressure to the annular chamber 7.2 in which the parking brake piston is held in the released position. hold The brake pedal 73 is movable from the first position to the second position and is connected to the conduit and A pressurized fluid is communicated from the conduit 70 to the miso q2 via an associated passageway 7q to connect the service block to the miso q2. Move the rake piston to the right position. In the second position of the control lever, the The pressure fluid source is connected by the control device to these conduits and to a drain (not shown) in the control device. When chamber 7 is depressurized, it is cut off from both the conduit and the depressurized conduit. , the combined force between the ribs 50 and 51I automatically moves the parking brake piston q6. and put it in a consistent state. The second manual control lever 76 used in the same control is the auxiliary fluid. Source 77 is pumped into the conduit to the annular chamber go and associated passages h-, 7g to form the third annular chamber. Push the piston Otsu0 to the left and move the parking brake piston so that the Sakai is in an unbalanced state. It is now possible to

産業上の利用可能性 この発明の作用は前述の説明から明瞭であると思４つれるか、以下に更に詳しく 説明する。車の移動中には第１制御レバー品は実線の第１位置にあって、制御装 置は加圧流体源を導管および関連する通路りθおよび駐車ブレーキ室７コ内へ連 通する。室７．２内のそのような流体圧力はばわＳＱの力を克服することにより 駐車ブレーキピストンｑ乙を完全に解放し、ペダル７３か実線の第１位置にある と、流体は弁７１により室幻から遮断される。このようにして、駐車ブレーキピ ストンが軸方向に左方へ移動すると、軸方向に圧縮されたばわりＯを介して常用 ブレーキピストンｑｏが解放する。このようにして、二つのピストンは解放され た状態に置かれる。Industrial applicability The operation of the invention should be clear from the foregoing description, or may be explained in more detail below. explain. When the vehicle is moving, the first control lever item is in the first position shown by the solid line, and the control device is in the first position. The location connects a source of pressurized fluid to the conduit and associated passageway θ and into the parking brake chamber 7. Pass. Such fluid pressure in chamber 7.2 is increased by overcoming the force of SQ Completely release parking brake piston qB and place pedal 73 in the first position indicated by the solid line. Then, the fluid is shut off from the chamber by valve 71. In this way, the parking brake pin When the stone moves to the left in the axial direction, it is compressed in the axial direction through the tension O. Brake piston qo is released. In this way, the two pistons are released be placed in a state of

常用ブレーキを掛けるには、ペダル７３を破線の第２位置へ移動させ、導管７０ から導管７ｑおよび常用ブレーキ作動室クヘ流本を操縦者の要求に釣合った圧力 で透析的に送るようにブレー子弁７／を位置させることによって達成できる。室 グ２が加圧されると、ばわ５０を克服してピストンｑＯを、係合板３２および互 い違いのブレーキ円板３１Ｉ、ブレーキ板３乙に対し直接右方向へ押しつけ、反 動板３０に押圧縮する１、このようにして、円板がハウジング９に対し摩擦で蹄 付けられて、スピンドル／乙すよひ７ランノ２０は回転しないよう保持される。To apply the service brake, move the pedal 73 to the second position indicated by the dashed line and open the conduit 70. The flow from the conduit 7q and the service brake operating chamber to the pressure commensurate with the operator's demands is maintained. This can be achieved by positioning the breaker valve 7/ to deliver dialysis. room When the plug 2 is pressurized, it overcomes the stiffness 50 and pushes the piston qO against the engagement plate 32 and the Press directly to the right against the different brake discs 31I and 3B, and then 1. In this way, the disc is pressed against the housing 9 by friction. The spindle/Otsusuyohi 7 runno 20 is held so that it does not rotate.

駐車状態においては、駐車ブレーキ室７−に対する流体圧力は動画装置６ｇを介 して排出される。圧力が所定値以下に下がると、ばね界およびりＯが作動して、 駐車ブレーキピストン１６を板３２に対し直接当接させるように片寄せ、ブレー キ円板３’ｌおよびブレーキ板３６を板３０に対し１罰縮して、スピンドル／６ を静止状態に保持する。In the parking state, fluid pressure to the parking brake chamber 7- is applied via the video device 6g. and is discharged. When the pressure falls below a predetermined value, the spring field and the spring O are activated, Move the parking brake piston 16 to one side so that it comes into direct contact with the plate 32, and then remove the brake. The disk plate 3'l and the brake plate 36 are reduced by 1 with respect to the plate 30, and the spindle/6 hold in a stationary state.
