Description
Technical field
The utility model belongs to electric power steering, and in particular to a kind of electric power steering applied to three-wheeled motor car fills
Put.
Background technology
The vehicle of tricycle front-wheel steer at present with steering be typically all using non helping hand mechanical steering structure or
Mechanical type hydraulic power-assisted steering structure.For non helping hand mechanical steering structure because not having power source, manipulation is heavy, easily causes driving
The manipulation fatigue of member, influences traffic safety；Although the manipulation of mechanical type hydraulic power-assisted steering structure is light, because hydraulic system
Typically all by devices such as hydraulic pump, oil pipe, pressure flow hybrid control valve, belt pulley, oil storage tanks, cost is high, volume is big, can not apply
On motor pedicab；In addition, the pressure of hydraulic pump is very big, can not effectively be controlled, it is easy to damage force aid system and
Vehicle part, so, seldom applied on three-wheeled motor car.
The content of the invention
To solve the above problems, the utility model provides a kind of electric power-assisted steering apparatus applied to three-wheeled motor car, bag
Input shaft, described input shaft one end closure disk are included, other end connection turns to output shaft, sets and turns on input shaft
Machine, the turning machine include servomotor, controller, torque sensor, and the servomotor is connected with controller, servomotor
Rotating shaft is connected with input shaft, and the torque sensor is arranged on input shaft, is connected by wire with controller, on the controller
Connect speed data collection device.
Further, the servomotor roller end is provided with gear, is screw-rod structure at the input shaft corresponding gear,
Servomotor and input shaft pass through gear and screw rod engagement connection.
The utility model cost is low, small volume, control are simple, solves former non helping hand mechanical steering device and manipulates heavy ask
Topic.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model concrete application schematic diagram；
Wherein, 1 is speed data collection device, and 2 be controller, and 3 be servomotor, and 4 be input shaft, and 5 be torque sensor, and 6 are
Steering wheel, 7 be output shaft, and 8 be turning machine.
Embodiment
The utility model embodiment, a kind of electric power-assisted steering apparatus applied to three-wheeled motor car, including input
Axle 4, the described one end closure disk 6 of input shaft 4, other end connection turn to output shaft 7, turning machine are set on input shaft 4
8, the turning machine 8 includes servomotor 3, controller 2, torque sensor 5, and the servomotor 3 is connected with controller 2, watched
Take the rotating shaft of motor 3 with input shaft 4 to be connected, the torque sensor 5 is arranged on input shaft 4, by wire and controller 2 is connected
Connect, speed data collection device 1 is connected on controller 2.
The roller end of servomotor 3 is provided with gear, is screw-rod structure at the corresponding gear of input shaft 4, and servo is electric
Machine 3 and input shaft 4 pass through gear and screw rod engagement connection.
Torque sensor obtains the steering moment signal of steering wheel, and controller control servomotor provides power-assisted, input shaft
By manual steering torque and servomotor steering moment superposition to output shaft.
