御器で制御したものである。In the embodiment of the braking system for a transport vehicle according to the present invention, in the transporting machine, the non-excitation actuated electromagnetic brake is provided on the transmission shaft of the reduction gear transmitting power from the prime mover. This electromagnetic brake is the front brake FB. The release and braking by the current flowing through the electromagnetic brake are released if the command input of the switch LS1 is ON and the current is positive, and the switch LS1 is OF.
If it is F, braking is performed. Normally (when the present invention is not used), LS1 is released in the ON state. The current value flowing in this electromagnetic brake is
When LS1 was switched to the OFF state, it rapidly became zero, so the electromagnetic brake had to be activated suddenly. By connecting this to a variable resistor (volume) to the current controller, The degree of braking is adjusted according to the situation at the site, such as inclination angle. However, the embodiment of the present invention is controlled by the current controller so as to gently change the braking force of the electromagnetic brake from small to large.

Electrical control is performed so that the braking force of the electromagnetic brake FB gradually increases from small to large over time.

Then, a release current flows from the current controller 1, the non-excitation actuated electromagnetic brake provided on the transmission shaft of the reduction gear device is released, and the vehicle is started and power is transmitted from the prime mover. When the start lever is returned to the stop position or the neutral position, the limit switch LS1 for detecting the stop or neutral position provided on the start stop lever is cut off, so that the braking force of the electromagnetic brake gradually changes from small to large within a certain period of time. The current controller 1 changes the current value so that the braking can be performed gently.

る。A negative-acting electromagnetic brake is also provided on a carrier truck that moves in connection with a power vehicle. The relay contact R2 a connected to the coil of the control timer TM1 of the rear brake RB is disconnected when electricity flows to the relay R2 to release the front brake, and is connected when the front brake works and the relay of R2 is not working. ing. Timer T
Since M1B is connected when the timer is not working, the electromagnetic brake RB of the carrier is released.
When the current flowing through relay R2 is cut off, relay contact R2
B is connected, and the fact that the electromagnetic brake of the motor vehicle is working is displayed on the display lamp of RL4. At this time, since the contact of R2 a is connected, current flows through the coil TM1 of the control timer, but the timer TM1b does not work until the set time. At this time, the timer TM1
RL4 says that B is connected to the rear brake and the rear brake is released, but the front brake of the power vehicle is in effect, and therefore the brake of the power vehicle is in effect.
Indicator lamp lights up. The relay contact R2a is connected, and after the set time of the timer TM1, the timer contact TM1B of the rear brake RB is disconnected and the rear brake RB is activated. Since the timer TM1 can be set to operate several seconds after the front brake is started, the timer TM1 is electrically controlled so that the braking start time of the transport vehicle is delayed from the braking start time of the motor vehicle. It will be.

衝撃が大きくなる不具合があった。As described in detail in the section of the above-mentioned prior art, the electromagnetic brakes conventionally used in transport vehicles are:
Since the spring forcibly operates by turning off the current, it takes an extremely short time from the start of operation to the end of braking. For this reason, the impact of stopping is inevitably great when the slope is descending. Since it is a braking system for railroad vehicles traveling on sloping ground, it is customary to provide multiple brakes with a large braking capacity. There was a problem that the shock was large.

That is, in order to gradually exert the braking force of the non-excitation actuated electromagnetic brake provided on the power vehicle, the brake release current is electrically controlled. It is possible to provide a shock-free stop device that is electrically controlled to start after the end.
