Electronic throttle valve device with vanes rotating through arc rack

Abstract

The invention provides an electronic throttle valve device with vanes rotating through an arc rack, and belongs to the technical field of electronic throttle valves. The electronic throttle valve device with the vanes rotating through the arc rack comprises a shell and a throttle valve body, wherein the shell covers the throttle valve body, the shell and the throttle valve body are fixed into a whole through bolts, a central air inlet is formed in the throttle valve body, a plurality of vanes are spliced into a complete circle, rotating pins are fixed at the tail ends of movable vanes, the movable vanes are connected to a bottom plate located on the throttle body through the rotating pins, a servo motor is installed on the throttle body, a motor gear of the servo motor is meshed with a middle large gear, the middle large gear and a middle pinion rotate coaxially, the middle pinion is meshed with an outer arc rack of a gear ring with the outer arc rack, inner teeth of the gear ring with the outer arc rack are meshed with a transmission gear, and then the movable wings are driven to rotate. According to the electronic throttle valve device with the vanes rotating through the arc rack, the movable vanes rotate stably, the air intake flow is stable, the air intake efficiency is high, the rotating precision of the movable vanes is improved, and it is ensured that an engine works under the optimal working condition all the time.

Description

technical field [0001] The invention belongs to the technical field of electronic throttle, and relates to a circular-arc rack rotary vane type electronic throttle device, which can ensure smooth and precise control of the air intake of the engine, so that the engine can work in the best range, and is beneficial to improving the engine speed. play a certain role in the overall performance. Background technique [0002] Electronic throttle is a flexible control system. As an important control part of the engine, it can precisely control the throttle opening to ensure proper intake air volume, reduce emissions, and improve vehicle power, economy and safety. [0003] The utility model patent with the publication number CN210087489U discloses an aperture type electronic throttle device, which adopts the rear end of the movable flap of the aperture to be hinged with the aperture gear, and fixes the movable flap of the aperture in the movement slot through a fixed pin. With the r...
