Oil pump is rotated and drives reduction box, and reduction box drives steel ring to rotate, so as to realize the traveling of vehicle.
The wheel electrical machine of built-in reducing gear, and the axle structure tried out in wheel electrical machine is devised, facilitate connecing for motor
Line and its inspection.The motor volume is small, and moment of torsion is big, and compact with reduction box is integrated, is compared by reasonable selection reduction box speed,
The output torque for sending out motor big, reduces engine speed, can meet the requirement of flat car underloading fast running.In empty wagons and gently
When carrying traveling, electric drive mode is switched to, by storage battery power supply, battery can carry out quick charge by charging pile, also may be used
Trickle charge is carried out with by vehicle-mounted motor.Need to be switched to hydraulic motor when heavy duty and climbing and pattern is operated alone, work as flat car
When running into the big slope of the gradient, electric drive can be used as auxiliary power.
Power drives oil pump by diesel engine, by fluid pressure line, hydraulic oil is sent to the high-pressure mouth of drive motor.Diesel oil is sent out
Motivation also gives battery charging simultaneously.The displacement of pedal can be converted to according to the selection of gear by digital letter when stepping on the gas
Number, the proportional multi-way valve of control hydraulic motor is distributed to, so as to control hydraulic motor to export corresponding moment of torsion and rotating speed.Or handle
Data signal gives the controller of motor, and Synchronization Control motor is rotated.
It is special to develop the power management system for being exclusively used in flat car.When flat car is in zero load, underloading, heavy duty climbing, by
Power management system analysis speed, climbable gradient and power etc., through specific algorithm computing after, determine that drive pattern is hydraulic motor
Drive pattern or In-wheel-motor driving pattern, and In-wheel-motor driving pattern auxiliary hydraulic motor drive pattern.
It is for so that any person skilled in the art can all make or use this public affairs to provide of this disclosure being previously described
Open.Various modifications of this disclosure all will be apparent for a person skilled in the art, and as defined herein general
Suitable principle can be applied to spirit or scope of other variants without departing from the disclosure.Thus, the disclosure is not intended to be limited
