The specific embodiment
Referring to Fig. 1-3, the output gear shaft 11 that the implementation case comprises input shaft 2, input gear 10, takes turns engagement with input tooth 10, input gear 10 is two finishing bevel gear cuter engaged transmission with output gear shaft 11, the corresponding torsion of driver output gear wheel shaft 11 increases the controller 28 of the servomechanism of output torque, the control motor 27 that drives servomechanism, driving control motor 27, and controlling motor 27 can be stepping motor, servomotor or DC machine etc.Between input shaft 2 and input gear 10, be provided with along with input shaft 1 and input gear 10 relatively rotate and the torsion bar 1 of the circumferential angle variation of the generation that links, between input gear 10 and input shaft 1, be fixed with the torque sensor 9 that detects torque and direction and transmit signal to controller 28, controller 28 receives torque sensor 9 signals, and processes the respective drive receiving and control motor 27 by driving the signal of servomechanism driver output gear wheel shaft 11.
Wherein, servomechanism comprises that interference fit is arranged at the worm gear 16 on output gear shaft 11, the worm screw 15 coordinating with worm gear, and worm screw 15 is connected through coupler 29 with control motor 27.Worm screw A cushion blocking 23 and worm screw B cushion blocking 24 are eliminated mechanical error and are vibrated the worm gear 16 bringing and mesh with worm screw 15 the uneven compliance producing.
In addition, controller 28 connects vehicle speed signal device, and receives vehicle speed signal, and the implementation case middle controller 28 can directly connect speed data collection device or gather vehicle speed signal on automobile.Control motor 27, torque sensor 9 are connected with controller 28 by wire with speed data collection device.
Wherein, spring 8 be becoming tight input gear 10 and output gear shaft 11 engagements, spring 8 is in order to adjust the gap of input gear 10 and output gear shaft 11 gears engagements and to eliminate the vibration that engagement irregularity produces.Torsion bar 1 one end flush fit is arranged in the axis hole of input gear 10, and the other end is fixed in the axis hole of input shaft 2 by torsion bar set pin 3.
Below in conjunction with specific works principle of the present utility model, further set forth the utility model.
When input shaft 2 applies moment of torsion, torsion bar 1 produces torsional deflection, and torque sensor 9 detects the size and Orientation of moment of torsion, converts electric signal transmission to controller 28; Controller 28 is controlled power-assisted size of current and the direction of motor 27 according to the calculated signals collecting; Motor 27 drives worm screw 15 rotations, and high-revolving worm screw 15, by the engaged transmission with worm gear 16, has increased the moment of torsion acting on output gear shaft 11.The engaged transmission of input gear 10 and 11 liang of finishing bevel gear cuters of output gear shaft has changed the steering torque acting in the actuator arrangement of angle, and motor 27 has been realized the object that increases angle actuator arrangement output torque through worm gear 16 and worm screw 15 speed reduction gearings, the size of the max. output torque of device can realize with the reduction ratio of worm screw 15 through increasing power, the change worm gear 16 of motor 27, until meet the required output torque of Vehicular turn.While being connected to vehicle speed signal as controller 28, this angle actuator arrangement can also increase " road feel " of chaufeur along with the size of the less output torque of increase of the speed of a motor vehicle, improves the safety of vehicular drive.
While being applied to the moment of torsion disappearance on input shaft 2, torsion bar 1 recovers distortion, and the moment of torsion that torque sensor 9 detects is zero, and controller 28 is controlled motors 27 and do not worked; Realized " the servo-actuated property " that turn to.
