Abstract
The invention relates to an electronic throttle valve actuating mechanism. The worm wheel and worm self-locking principle is adopted for eliminating the interference with a motor due to inlet airflow, mechanical vibration and the like of a throttle valve. The electronic throttle valve actuating mechanism comprises the motor, a first-stage transmission mechanism, a worm wheel and worm transmission mechanism and the throttle valve. An output shaft of the motor is fixedly connected with a driving gear in the first-stage transmission mechanism. A driven gear in the first-stage transmission mechanism is connected with a worm in the worm wheel and worm transmission mechanism. A worm wheel in the worm wheel and worm transmission mechanism is fixed installed on a rotary shaft of the throttle valve. According to the electronic throttle valve actuating mechanism, the worm wheel and worm transmission mechanism with the self-locking function is adopted for transmitting the torque, and the unidirectional torque transmission of the motor to the throttle valve is achieved; a return spring part is omitted, and the cost is reduced while the structure is simplified; the mechanical failure rate is decreased. In addition, the motor can work by means of quiescent current under non-rotation working conditions, and thus the purpose of energy conservation is achieved and the service life of the motor is prolonged.
Description
Technical field
The present invention relates to a kind of electronic throttle actuator, it utilizes worm and gear self-lock mechanism to eliminate the interference to motor such as charge air flow, mechanical vibration of closure, and eliminate return spring parts, designs simplification meets power conservation requirement simultaneously.
Background technique
As shown in Figure 1, electronic throttle actuator comprises driver part, parallel-axes gears reducing gear and closure, and wherein driver part is stepper motor or brush direct current motor.Electronic throttle actuator is often subject to the charge air flow disturbance of closure in use, the interference such as mechanical vibration, if these interference react on stepper motor as driver part or brush direct current motor by parallel-axes gears reducing gear, clockwise and anticlockwise frequent starting will be there is to the motor of rotor-position tracing control, the rotor-position fluctuation suppressing above-mentioned interference to bring with this, eliminate interference effect, but due to system damping, rotary inertia, the impact of the factors such as backlash, motor engineering being in work near zero load operating mode is difficult to suppress interference in this way, for this reason, the electronic throttle of prior art usually as shown in Figure 1, adopt and add at the output terminal of parallel-axes gears reducing gear the output torque that a return spring increases motor, carry out " dieing out " throttle inflow air-flow, the parameter perturbations such as mechanical vibration, realize the tracing control of rotor-position, but the motor in this kind of structure and be still bi-directional torque transmission between closure, the one-way moment transmission of motor to closure can not be realized thoroughly to eliminate interference effect, adopt the structure of return spring Ye Shi electronic throttle actuator to become complicated simultaneously, improve cost of production and rate of fault, also increase the current drain of motor static reactive moment of torsion.
Summary of the invention
The object of the present invention is to provide a kind of electronic throttle actuator, utilize worm and gear self-lock mechanism to eliminate the electronic throttle actuator of the interference such as throttle inflow air-flow, mechanical vibration, while simplifying structure, also meet power conservation requirement.
