摘要: A cooling system and method for an auxiliary braking device of a hydrogen fuel cell truck, are provided in consideration that auxiliary braking force generated by the regenerative braking of the motor may be unnecessary and the brake resistor may be unnecessary when a sufficient amount of auxiliary braking force is generated alone by the operation of a retarder. A portion of thermal energy generated by the retarder is distributed to a stack cooling system so that the portion of thermal energy is removed by the stack cooling system. Accordingly, due to sufficient cooling of the retarder, a sufficient amount of auxiliary braking force is provided, and the brake resistor that has consumed surplus electrical energy generated by regenerative braking is removed.

摘要: A method for braking a train set having guiding and guided locomotives interconnected by a time multiplex train bus, includes detecting actual operating current of the guided locomotive, detecting actual operating current of the guiding locomotive, detecting maximum return current, detecting pneumatic braking request of compressed air brake line, determining maximum return current and target braking of the guided locomotive from actual operating current of the guided locomotive, actual operating current of the guiding locomotive, maximum operating current and pneumatic braking request of the brake line, and electrically braking the train set using electrical target braking, while not exceeding maximum return current of the guided locomotive. The maximum current fed back by the guided locomotive is known, and the guided locomotive controlled through the main air line is braked while not exceeding the maximum return current. The braking force is divided by blending among E and pneumatic brakes.

摘要: An electrically-driven mining vehicle includes an obstacle detector, a speed detector, and an alarm. The alarm outputs a first warning, which urges an operator of the electrically-driven mining vehicle to operate a regenerative brake pedal that actuates only the regenerative brake device, and a second warning, which urges the operator to operate a cooperative brake pedal that uses the regenerative brake device and the mechanical brake device in combination. If the travel speed of the vehicle is included in a low speed range in which no difference can be considered to exist in distance between a first braking distance upon actuation of only the regenerative brake device and a second braking distance upon operation of a cooperative braking, a signal for performing the first warning is outputted earlier by at least a warning time interval.

摘要: The present invention provides a braking control apparatus capable of preventing or reducing a change in a deceleration of a vehicle. The braking control apparatus is configured to change a braking force to be generated by a frictional braking device so as to achieve a calculated target braking force, and generate a braking force corresponding to a difference between the braking force to be generated by the frictional braking device and the target braking force with use of an electric braking device, when a predetermined condition is satisfied.

摘要: A magnetic suspension of a vehicle for an underpass with a ferromagnetic rail of an arbitrary cross section is proposed, which comprises permanent magnets and electromagnets mounted to be able to be attracted to a ferromagnetic rail. Permanent magnets are installed being arranged to control the force of attraction to the ferromagnetic rail. The position and/or mass of the permanent magnets can be adjusted before starting the movement under the weight of the vehicle and the transported load.
