Embodiment 1

[0020] Such as figure 1 An AMT-based electronic throttle controller shown includes: an aluminum substrate 8, a casing 10, a casing cover 1, a control mechanism, an actuator and a position feedback mechanism, the bottom of the casing 10 is connected to the aluminum substrate 8, and the casing 10 The top is connected to the housing cover 1; the actuator includes: gear reduction device, bearing 12, copper sleeve and return spring, the gear reduction device, bearing 12, shaft sleeve 15, and return spring 14 are arranged in the housing 10, and There is a support plate 11, the support plate 11 is set at the lower end of the gear reduction device, the support plate 11 is provided with a mounting hole 17, and the bearing 12 is embedded in the support plate 11; the control mechanism is composed of a motor 2 and a control circuit board 9, and the motor 2 is fixed. On the housing cover 1, it is arranged inside the housing 10. The output shaft of the motor 2 is connected to the gear r...

Embodiment 2

[0024] Such as Figure 4 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the position feedback mechanism in this embodiment is composed of a magnet 5 and a Hall element 24, the magnet 5 is embedded in the shaft end of the gear II shaft 4, and the Hall The element 24 is arranged on the position corresponding to the magnet 5 on the control circuit board 9 .

[0025] The Hall element 24 can sense the position of the magnet 5, so that the movement of the wire reel 16 is transmitted through the second-stage gear, corresponding to the rotation angle of the magnet 5 on the gear II shaft, and at the same time controls the Hall element 24 on the circuit board 9 The rotation position of the magnet 5 is sensed, and the position information is fed back to the control circuit board 9 for information processing.

Embodiment 3

[0027] This embodiment is basically the same as Embodiment 1, except that the motor 2 in this embodiment is a DC brushless motor, and the output shaft of the DC brushless motor is connected to the gear reduction device.

[0028] Compared with traditional DC motors, brushless DC motors have the advantages of small size, light weight, high efficiency, high reliability, and good stability. The use of brushless DC motors has low cost, high work efficiency and stability.

Abstract

The invention relates to the technology of throttle control, and particularly provides an electronic throttle controller based on an AMT. The electronic throttle controller based on the AMT comprises an aluminum base plate, a shell, a shell cover, a controlling mechanism, an executing mechanism and a position feedback mechanism. The bottom of the shell is connected with the aluminum base plate, and the top of the shell is connected with the shell cover. The executing mechanism comprises a gear reducer, a bearing, copper bushes and a reset spring. The controlling mechanism is composed of a motor and a controlling circuit board. The executing mechanism further comprises a steel wire coil which is arranged outside the shell cover, the steel wire coil is coaxially connected with an output shaft of the gear reducer, the shell is provided with a mounting hole used for installing a flexible shaft connected with the steel wire coil, a wire clamping hole is formed in the steel wire coil, and the steel wire stay wire on the flexible shaft is connected with the steel wire coil through the wire clamping hole. The electronic throttle controller based on the AMT is simple in structure and convenient to maintain, the performance is stable, the manufacturing cost is low, and the popularization is suitable.

Description

technical field [0001] The invention relates to throttle control technology, in particular to an AMT-based electronic throttle controller. Background technique [0002] Due to environmental protection, economy, reliability and other reasons, most models now use AMT-based electronic accelerators. The characteristic of AMT-based electronic accelerators is that the accelerator pedal only represents the driver's operation intention, and the final control of the throttle is controlled by the controller. The device is complete. [0003] The throttle opening is controlled by the controller, and the throttle opening is collected in real time by the sensor that detects the throttle position, and the position feedback is performed for the closed-loop control. The throttle position sensor is the only detection element of the throttle position. The voltage signal can accurately detect the continuous rotation angle of the throttle valve. [0004] The existing throttle sensor controls ...
