衝突試験用台車のブレーキ装置。 A collision test truck that collides with a test vehicle at a predetermined speed is equipped with a hydraulic brake, and the brake is activated to stop the truck after the collision so as not to hit the test vehicle twice. A control system consisting of a hydraulic circuit with a control valve that can be freely switched between an oil supply side that supplies pressure oil from a device to the brake and an oil drain side that drains oil from the brake, and a control circuit for the control valve. The control circuit is activated by an acceleration sensor and a signal from the sensor generated at the time of a collision, and continuously outputs a refueling signal that switches the control valve to the refueling side until it is reset by a reset switch. 1. A braking device for a collision test trolley, comprising: a relay for controlling the refueling signal; and a timer on the output side of the relay, the timer delaying the refueling signal by a predetermined time and inputting the signal to the control valve.
