Auxiliary device and method for cleaning electronic throttle valve plate

Abstract

The invention relates to an auxiliary device and a method for cleaning an electronic throttle valve plate, and belongs to the technical fields related to mechanical engineering and vehicle engineering. The device part mainly includes a base, and a throttle cleaning agent lifting mechanism is provided on the base; the left side of the base is fixedly connected to the first bracket, the first bracket is slidingly matched with the throttle mounting seat, and the throttle mounting seat is located in the throttle cleaning agent lifting mechanism Above; the right side of the base is fixedly connected to the second bracket, and the second bracket is provided with a positioning mechanism for controlling the opening of the throttle valve plate; wherein the positioning mechanism is located above the throttle mounting seat. By designing a new structure, this device can immerse the lower part of the throttle valve plate in standard throttle valve cleaning agent, so as to remove carbon deposits on the throttle valve plate without basically damaging the throttle valve seal, and reducing the burden on technicians. Physical hazards.

Description

technical field [0001] The invention relates to technical fields related to mechanical engineering and vehicle engineering, in particular to an auxiliary device and method for cleaning an electronic throttle plate. Background technique [0002] Throttle valve (throttle valve) is a controllable valve used to control the air entering the engine. After entering the intake pipe, it is mixed with gasoline to become a combustible mixture and participate in combustion to do work. [0003] In terms of control mode and structure, throttle valves generally include mechanical throttle valves and electronic throttle valves. [0004] The mechanical throttle generally applies a torque to the valve plate through a zipper (or called a pull wire) to overcome the torque of the torsion spring of the throttle assembly itself, so that the valve plate rotates relatively to realize the opening of the throttle (that is, intake air). [0005] The main difference between the electronic throttle valv...

Problems solved by technology

[0021] Although this device can keep the valve plate in the open state for a long time, it still belongs to "removing and cleaning the throttle valve with carburetor cleaning agent" in essence, because the throttle valve assembly cannot be rotated as a whole after it is fixed, so there are still influences. Disadvantages of service life of valve and health of technicians

[0022] At the same time, the existing electronic throttle valves all use a servo motor and a torque conversion mechanism to drive the valve plate to rotate, and the servo motor is usually located inside the throttle valve assembly, and the non-output end of the output shaft of the servo motor exposed outside the motor housing is only It is about 2mm, so it is difficult to use the rotating disk and the matching structure in the above scheme to drive the output shaft of the servo motor to rotate
