Detailed description of the invention
Referring to Fig. 1, Fig. 2, the present invention includes pedal tread 1, pedal arm 10, drive motor 8, transmission device and operating-controlling mechanism.Drive motor and transmission device are arranged on pedal arm, and operating-controlling mechanism is arranged on the console place of operator's compartment.Rotated by operating-controlling mechanism control drive motor, drive motor drive transmission device moves, thereby realizes the angular adjustment of the relative pedal arm of pedal tread.
Still, referring to Fig. 1, Fig. 2, transmission device comprises worm screw 5, worm gear 3, pedal tread bracing frame 2 and turning cylinder 4.Worm screw is connected through coupler 7 with drive motor output shaft, and coupler is selected to be had elastic damping, noiseless, do not need the diaphragm coupling that lubricates, transmission accuracy is high.Worm screw, the intermeshing connection of worm gear, pedal tread bracing frame and pedal tread are welded and fixed, and pedal tread bracing frame drives institute's pedal tread synchronously to rotate while rotation.Described turning cylinder 4 is successively through worm gear, pedal tread bracing frame and pedal arm, and a side of turning cylinder is fixedly connected with worm gear, pedal tread supporting framework circumferentially through flat key 14, and turning cylinder opposite side and pedal arm form hinged.Described transmission device utilizes Worm Wheel System, can not only change the direction of transfer of moment of torsion, and there is reverse self-locking function, the moment of torsion being transferred out by drive motor can only pass to worm gear by worm screw, and worm gear cannot rotate by reverse drive worm screw, therefore can carry out the Das Gaspedal face angle after adjusting lockedly, while preventing chaufeur pushes pedals face, pedal tread, because of the stressed pedal tread automatic rotation that causes, departs from set angle and cause failure of adjustment.Stable for ensureing worm gear, worm movement, set up worm screw support sleeve 6, worm gear support sleeve and pedal arm are fixed, and the bar portion of worm screw is through worm screw support sleeve, and worm screw support sleeve free-running fit.Drive motor 8 is fixed on drive motor support 9, and drive motor support and pedal arm 10 are fixing, and drive motor is selected stepper drive motors,
Referring to Fig. 1, operating-controlling mechanism comprises CPU11, angular transducer 13 and instrument carrier panel 12, and angular transducer is arranged on pedal tread back, and angular transducer is delivered to CPU by the pedal tread angle signal of collection by circuit; CPU connection instrument carrier panel, the integrated LCDs of instrument carrier panel, CPU accepts button conditioning signal, controls drive motor and does rotation forward or backwards.
Referring to Fig. 3, the principle of work of operating-controlling mechanism is as follows: whether driver is comfortable by first examination pedal subjective feeling pedal tread angle, in the time that sensation angle causes foot uncomfortable, LCDs button on adjusting apparatus dash board, CPU is by accepting instrument carrier panel touch key-press conditioning signal, through signal, processing converts impulse singla to and passes to stepper drive motors, controlling drive motor rotates forward or backwards, drive motor output torque passes to transmission device by coupler, worm gear rotates and drives pedal tread fine setting through pedal tread bracing frame, thereby adjust to gradually the work angle of pedal tread to the most comfortable.
Referring to Fig. 4, workflow of the present invention is as follows: in vehicle energising situation, driver tramples Das Gaspedal Mian Shi subjective feeling foot angle sensation, as uncomfortable, by adjusting the touch key-press in instrument carrier panel liquid crystal display, CPU control unit receives after key information, carry out signal processing and be converted to stepper drive motors electronic pulse signal applicatory, stepper drive motors receives the impulse singla that microprocessor sends, carry out forward or reversion according to impulse singla information, stepper drive motors can be controlled the rotation number of turns accurately according to impulse singla, carry out accurate transmission, when pulse-free signal input, servo drive motor can not rotate.The torque of servo drive motor is passed to worm screw through diaphragm coupling, drives worm screw rotation, and under the drive of worm screw, worm gear rotates, and worm gear rotates and drives turning cylinder to rotate, and turning cylinder drives pedal tread bracing frame to rotate, thereby realizes the angular adjustment of Das Gaspedal face.The angle detecting sensor that pedal tread back arranges, can accurately detect the pedal tread angle of vehicle on level road, by the signal transmission of angular transducer, can be in dashboard displays clearly demonstrates pedal tread angle storage.In the time that different driver's steering vehicles causes accelerator pedal angle to change, vehicle owner can accurately give the angle that set early stage for change, and whole adjustment System quits work after angular adjustment completes.
