摘要： PURPOSE:To perform braking safely and to improve operationability by driving the operational arm of brake with a spring through a cam while releasing with high pressure air then driving with high pressure air to be controlled through a foot valve. CONSTITUTION:Upon bringing an exchange valve 35 to the position 35a, the air is discharged from a piston cylinder 26 into the atmosphere. Consequently a cam 38 is rotated to the left by a spring 32 while the arm 20 is also rotated to the left, and the brake band is pulled to function the brake. Upon exchange of the valve 35 to the position 35b, high pressure air is supplied into the cylinder 26 to rotate the cam 38 to the right against the force of the spring 32 thus to release braking. Upon stepping of a pedal 36 prior to complete release of braking, high pressure air is supplied to the piston cylinder 25 to extend the piston rod accordingly. Consequently the arm 20 will rotate to the left to function the brake proportionally with the force regulated by the valve 36.
摘要翻译：目的：为了安全地进行制动，通过用弹簧通过凸轮驱动制动器的操作臂，同时用高压空气释放，然后用高压空气驱动，通过底阀控制，来提高操作性。构成：在将交换阀35带到位置35a时，空气从活塞缸26排出到大气中。因此，凸轮38通过弹簧32向左旋转，同时臂20也向左转动，制动带被拉动以起作用。当将阀35更换到位置35b时，高压空气被供应到气缸26中以克服弹簧32的力将凸轮38向右旋转，从而释放制动。在完全释放制动之前踏上踏板36时，将高压空气供应到活塞气缸25，以相应地延伸活塞杆。因此，臂20将向左旋转以与由阀36调节的力成比例地起作用。

摘要： PURPOSE:To prevent a hydraulic pump and a hydraulic motor from damaging, by providing a charge signal valve which can be switched through charge pressure so that a pilot pressure operating part of a brake control valve is drained when charge pressure is decreased. CONSTITUTION:When charge pressure is decreased, pilot pressure applying to a pilot pressure operating part 25 of a charge signal valve 21 is decreased and the signal valve 21 is returned to a No.1 position (a). Pilot pressure of a brake control valve 17 is drained through the signal valve 21 and a brake 13 is operated. Signal pressure to servo-controllers 15 and 16 of a hydraulic pump 1 and a hydraulic motor 3 is drained through the No.1 port (a) of the brake control valve 17, which becomes powerless and does not operate a car speed control valve 29, and a car body is stopped automatically due to decrease of the charge pressure. With this, the damage resulting from cavitation of the hydraulic pump and the hydraulic motor is prevented from occurring.

摘要： PURPOSE:To allow small operating force to produce large braking force in a braking device, which generates the braking force in compliance with the amount of movement of a rod or the like interlocked with the operating lever, by applying an additional braking force given by a brake cylinder. CONSTITUTION:Stamping on a lever 12 will oppose the force of No.1 rod 11 to the initial force set at a compression spring 10, so that No.2 rod 6 and a link 8 swing a lever 5 in the direction as fastening the brake band 2 while holding the initial condition of brake disengaged. A further stamping of the level 12 in order to let the force of the rod 11 increase exceeding the initial spring force of the spring 10 will shrink the spring 10 till the balanced spring force with the aid of link 8 and rod 9 to produce a relative movement between the rods 11 and 6, so that a variable pressure-reducer valve 7 makes expansion and the cylinder 15 is connected with a tank 31, when the pressure in the cylinder 15 drops down to the pressure balanced at the time. Thereby a compression spring 19 is expanded and the differential force between the spring force and cylinder 15 is transmitted to the lever 5. Thus the braking force is increased.
