目前,一般汽车发动机采用的节汽门,与自动变速机构是分开控制的,发动机的控制与自动变速控制不能很好自动匹配。不同车型的发动机,其参数又不同。因此,匹配更困难。本发明是将一组滑轮,扭簧、角位移传感原件与驱动电机组成的执行器。自动将油门踏板的信号,根据电子自动变速系统的要求去控制,补偿发动机的节汽门,以达到优化整车的匹配。At present, the throttle valve used in general automobile engines is controlled separately from the automatic transmission mechanism, and the control of the engine and the automatic transmission control cannot be automatically matched. Engines of different models have different parameters. Therefore, matching is more difficult. The invention is an actuator composed of a group of pulleys, a torsion spring, an angular displacement sensing element and a driving motor. The signal of the accelerator pedal is automatically controlled according to the requirements of the electronic automatic transmission system, and the throttle valve of the engine is compensated to achieve the optimal matching of the whole vehicle.

With a torsion spring, torque can only be transmitted in one direction, and the opposite direction has no effect. The driven pulley is mounted on the drive motor shaft through bearings. A shift block fastened by screws is mounted on the root of the drive motor shaft. Through the screws on the passive pulley, the torque in the force direction of the driving motor and the driving pulley is transmitted to the passive pulley, which acts as a one-way wheel, and the passive pulley drives the throttle valve through the throttle cable.

如图1所示,本发明由踏板拉索(19)牵动主动滑轮(21)。角位移传感器(14)上的芯轴(5),装上带有轴承(15)的主动滑轮(21),通过主动滑轮(21)上的螺钉支点(8)、(10)、(11)装上扭簧(9)及被动滑轮(12)上的螺钉支点(8)、(10)、(11),与被动滑轮(12)连接将扭矩传递到被动滑轮(12)。主动滑轮(21)通过扭簧(9),只能向一个方向传递扭矩,相反方向无效。被动滑轮(12)通过轴承(15)装在驱动电机(1)轴的前端。驱动电机(1)轴的根部装上由螺钉(3)紧固的拨块(4)。通过被动滑轮(12)装上的螺钉(16),靠在能传递驱动电机(1)扭矩的拨块(4)上。将驱动电机(1)与主动滑轮(21)受力方向一致的扭矩通过拨块(4)传给被动滑轮(12),但又可不影响主动滑轮(21)的角位置,起到单向轮的作用。被动滑轮(12)通过油门拉索(21)连接牵动节气门。支架(2)上固定的定位块(4),控制被动滑轮(12)的起始位置。角位移传感器(14)与驱动电机(1),由支架(2)通过螺钉组(6)、(7)连接,扭簧(4)内部装上扭簧轴(20),轴承(15)的轴向定位通过内卡簧(13)和外卡簧(17)完成。As shown in Figure 1, the present invention drives driving pulley (21) by pedal cable (19). Mandrel (5) on the angular displacement sensor (14), load onto the driving pulley (21) that has bearing (15), pass the screw fulcrum (8), (10), (11) on the driving pulley (21) Load onto the screw fulcrum (8), (10), (11) on the torsion spring (9) and the driven pulley (12), be connected with the driven pulley (12) and transmit the torque to the driven pulley (12). Driving pulley (21) can only transmit torque to one direction by torsion spring (9), and the opposite direction is invalid. Driven pulley (12) is contained in the front end of drive motor (1) shaft by bearing (15). The root of the drive motor (1) shaft is loaded onto the shifting block (4) fastened by the screw (3).

The driving motor (1) is transmitted to the passive pulley (12) through the shifting block (4) with the torque in the same direction as the driving pulley (21), but the angular position of the driving pulley (21) can not be affected, so as to act as a one-way wheel. role. Passive pulley (12) connects and affects throttle valve by throttle cable (21). The fixed positioning block (4) on the support (2) controls the starting position of the passive pulley (12).
