Accompanying drawing explanation
Fig. 1 is the structural representation of power steering system of the present utility model.
Detailed description of the invention
As shown in Figure 1, the servo steering system of the utility model combination drive comprises pure electric steering mechanism and electric hydraulic power-assisted steering mechanism, pure electric steering mechanism comprises storage battery 6, EPS controller 5, EPS motor 4 and torque sensor 3, torque sensor 3 is arranged on steering column 2, for gathering the torque of steering handwheel 1, bearing circle 1 is fixedly connected with steering column 2, EPS motor 4 is arranged on steering column 2, steering column 2 is driven by turning cylinder, EPS controller 5 is connected with EPS motor 4, for controlling EPS motor 5 start and stop, the mouth of torque sensor 3 is connected with the input end of EPS controller 5, EPS controller 5 is sent to for steering wheel torque signal will be collected, storage battery 6 is connected with EPS controller 5, as the power resources of EPS motor 4, electric hydraulic power-assisted steering mechanism comprises electrokinetic cell 11, electric machine controller 10, steer motor 9, power steerig pump 8 and deflector 7, deflector 7 is connected with power steerig pump 8 oil circuit, steer motor 9 and power steerig pump 8 are mechanically connected, steering controller 10 and steer motor 9, electrical source of power 11 is all connected by high tension cord with steering controller 10, and electrical source of power 11 is the energy source of steer motor 9.Steering controller 10 is connected by CAN line with EPS controller 5, for the communication between pure electric boosted and electric hydaulic force aid system.
In the present embodiment, storage battery adopts 24V storage battery, and EPS motor is 24V DC brushless motor, and steer motor is phase asynchronous alternating current dynamo.
Above-mentioned servo steering system has three kinds of mode of operations, and when not beating direction, pure electric boosted mechanism and electric hydraulic power-assisted steering mechanism all do not work, and are all in stopped status; When beating direction, pure electric steering mechanism works immediately, and transmit working signal to electrohydraulic steering mechanism simultaneously, make electrohydraulic steering system work, power steering electric boostedly to be provided with electric hydaulic power-assisted with joint efforts jointly by pure; When pure electric booster turning mechanism breaks down, electrohydraulic steering system works always, and power steering is provided by electric hydraulic power-assisted steering system completely.Specific works process is as follows:
When not beating direction, it is that 0, EPS controller 5 inputs without dtc signal that torque sensor 3 collects dtc signal, controls EPS motor and shuts down; EPS controller 5 sends halt command to electric machine controller 10 by CAN line simultaneously, makes to turn to also to be in stopped status, and system power dissipation is almost nil.
When beating direction, torque sensor 3 will detect that steering wheel torque signal is sent to EPS controller 5, EPS controller 5 works after receiving dtc signal immediately, EPS controller 5 sends work order to electric machine controller 10 by CAN line simultaneously, electric machine controller 10 controls steer motor work, and now, power steering is electric boostedly made a concerted effort to provide with electric hydaulic power-assisted by pure.
When pure electric power steering breaks down, EPS controller 5 sends work order to steering controller 10 by CAN line always, steering controller 10 controls electric hydraulic power-assisted steering system and works always, and power steering has electric hydraulic power-assisted steering system to provide completely.
