Abstract
A kind of opposed double-motor driving devices of EPS of the present invention, category automobile electric booster steering system field.The present invention is to provide for bigger power-assisted ability.The technical solution adopted for the present invention to solve the technical problems is：Torque sensor signal in EPS is divided into two into two-way, the power supply and signals of vehicles that vehicle is provided also are divided into two into two-way；Using two controllers, each controller receives torque sensor signal and vehicle power supply and signals of vehicles all the way, and controls a motor respectively；Two motors are arranged in the same two ends of worm screw, while drive worm screw to drive worm gear wheel, so that power-assisted is doubled；The housing for installing motor has two flanges, while worm screw two ends are respectively disposed with dog, with the dog connection on corresponding rotor, realizes that moment of torsion is transmitted.The beneficial effects of the invention are as follows：Double EPS power-assisted ability, realization is matched with more big load vehicle.
Description
Technical field
The invention belongs to electric automotive power-assisted steering machine system regions, and in particular to the electricity of electric boosting steering system
Machine actuating device.
Background technology
Electric boosting steering system (EPS) is now vigorously promoted the use in, with automobile steering system.EPS presses motor
The difference of installation site, is divided into different types, have C-EPS (Column type Electric Power Steering,
Pipe column type electric power-assisted steering system system), P-EPS (pinion type Electric Power Steering, pinion type
Electric boosting steering system) and R-EPS (Rack type Electric Power Steering, rack-and-pinion electric power steering
System).P-EPS extends DP-EPS (Double-pinion type Electric Power again in actual use
Steering, double-pinion type electric boosting steering system).For C-EPS, P-EPS and DP-EPS, it is constituted substantially all includes
Torque sensor, controller, motor and Worm Wheel System pair.Its operation principle is exactly：During steering wheel rotation, torque sensor
The moment of torsion for applying on the steering wheel is detected, and torque signal is sent to controller, controller receives torque signal, and combines
Vehicle GES, to motor, motor work output torque drives worm screw to output current, then is increased by secondary deceleration of Worm Wheel System
After torsion, torque is delivered to worm gear output.
But with being continuously increased for EPS matching car loads, the power of existing EPS motors seems not enough, and develops
More powerful motor and matching controller difficulty are very big, it is also not possible to unlimited expanded motor power.
The content of the invention
The present invention provides a kind of opposed double-motor driving device, to increase power-assisted ability, it is adaptable to C-EPS, P-EPS and
DP-EPS。
The technical solution adopted for the present invention to solve the technical problems is：By the torque sensor signal one in EPS
It is divided into two one-tenth two-way, the power supply and signals of vehicles that vehicle is provided also are divided into two into two-way, signals of vehicles includes that igniting is believed here
Number, GES and engine rotational speed signal；Using two controllers, each controller receive torque sensor signal all the way and
Vehicle power supply and signals of vehicles, and a motor is controlled respectively；Two motors are arranged in the same two ends of worm screw, while driving
Worm screw drives worm gear wheel, so that power-assisted is doubled.In this programme, the housing for installing motor has two flanges, for pacifying
Dress motor, while worm screw two ends are respectively disposed with dog, its one end dog is monolithic construction with shaft, and other end dog is in snail
After bar is installed on housing, it is pressed onto on the small end of worm screw by way of press-fiting.The dog at worm screw two ends turns with corresponding motor
Dog docking on son, realizes that moment of torsion is transmitted, and be mounted on cushion pad between motor dog and worm screw dog.
The beneficial effects of the invention are as follows：On the basis of prior art ability, double power-assisted ability, realize with more
The matching of big load vehicle.

In figure：1. motor, 2. bolt, 3. housing, 4. worm screw, 5. worm gear, 6. dog, 7. cushion pad.
Specific embodiment
Principle of the invention and assembly relation are reflected in Fig. 1 to Fig. 2 completely.
During steering wheel rotation, torque sensor detects the moment of torsion for applying on the steering wheel, and torque signal is converted into
Electric signal is divided into two-way and is sent to two controllers.The power supply and signals of vehicles that vehicle is provided also are divided into two into two-way and are sent to
The two controllers, here signals of vehicles include ignition signal, GES and engine rotational speed signal.Each controller according to
Received torque signal, and vehicle signals of vehicles is combined, while giving motor (1) output current respectively, two motors (1) are same
When work output torque, drive worm screw (4) to drive worm gear (5) to rotate, output torque.The housing (3) for installing motor (1) has two
Flange, two motors (1) are separately mounted on two flange faces of housing (3), are tightened by bolt (2).Motor (1) is arranged in
The two ends of worm screw (4), worm screw (4) two ends are respectively disposed with dog, and its one end dog is monolithic construction with shaft, and the other end is convex
Pawl (6) is pressed onto on the small end of worm screw (4) after worm screw is installed on housing (3) by way of press-fiting.Worm screw (4) two ends
Dog and the dog docking on corresponding rotor, realize that moment of torsion is transmitted, and be respectively mounted between motor dog and worm screw dog
There is cushion pad (7).
Claims (4)
1. opposed double-motor driving devices of a kind of EPS, it is characterized in that：The torque sensor signal of EPS is divided into two into
Two-way, vehicle power supply and signals of vehicles are also divided into two into two-way, and signals of vehicles includes ignition signal, GES and hair here
Motivation tach signal；Using two controllers, each controller receives torque sensor signal and vehicle power supply and vehicle all the way
