摘要： An electrical circuit for driving an electrically driven vehicle such as a dump truck is capable of preventing occurrence of accidents caused by an erroneous operation and thereby increasing safety by providing an arrangement such that the vehicle cannot start unless all necessary operations have been completed before starting. For this purpose, a power source of a control box controlling an exciting current for a generator is turned on to generate the exciting current only when all necessary operations have been completed. This is achieved by connecting a plurality of switches corresponding to various operations in series to a power source relay and thereby causing the power source relay to be actuated upon closing of all of these switches. The circuit also enables the motors to be utilized as generators to provide dynamic braking for the truck.

摘要： A control device for controlling accelerator and brake switches is designed to prolong life of the accelerator and brake switches as well as life of electromagnetic contactors for the accelerator and brakes which are energized and deenergized by these switches. According to the invention, once the accelerator switch has been turned on by depression of an accelerator pedal, the ON state of the accelerator switch is maintained unless a brake pedal is subsequently depressed. Similarly, once the brake switch has been turned on by depression of the brake pedal, the ON state of the brake switch is maintained unless the accelerator pedal is subsequently depressed. To this end, the control device comprises changeover valves respectively actuated by the accelerator and brake pedals, bistable means for performing a mechanical bistable operation by means of air supplied through the changeover valves and accelerator and brake switches actuated in correspondence to two positions of the bistable means.
摘要翻译：用于控制加速器和制动开关的控制装置被设计为延长加速器和制动开关的寿命以及用于加速器和制动器的电磁接触器的寿命，这些开关由这些开关通电和断电。根据本发明，一旦通过按下加速器踏板来接通加速器开关，则除非制动踏板随后被压下，否则保持加速器开关的接通状态。类似地，一旦通过按下制动踏板来接通制动开关，则除非加速踏板随后被压下，否则保持制动开关的接通状态。为此，控制装置包括由加速器和制动踏板分别致动的转换阀，用于通过转换阀供给的空气进行机械双稳态操作的双稳态装置和对应于双稳态的两个位置致动的加速器和制动开关手段。
