Abstract

The invention discloses a plastic shell light-weight electronic throttle valve which comprises a throttle valve body, a throttle valve shaft, a throttle valve piece, a gear transmission assembly and a driving motor, the throttle valve body is composed of a plastic shell and a metal lining, the metal lining is embedded in the plastic shell, and the metal lining is provided with a throttle valve air channel, an upper shaft hole and a lower shaft hole; one end of the throttle shaft penetrates through the upper and lower shaft holes and is rotatably connected with the metal lining through a bearing, and the other end is connected with the driving motor through a gear transmission assembly; and the throttle valve sheet is sleeved on the throttle valve shaft and is driven by the throttle valve shaft to rotate in the throttle valve air passage. A traditional die-casting aluminum shell structure is omitted, the plastic valve body structure that the metal insert is wrapped by the plastic body is adopted, and the weight of the throttle valve body is reduced.

Description

technical field [0001] The invention relates to the technical field of an electronic throttle, in particular to a lightweight electronic throttle with a plastic shell. Background technique [0002] The throttle valve is a controllable valve that controls the air entering the engine. After the gas enters the intake pipe, it will be mixed with gasoline, diesel, etc. to become a combustible mixture, thereby burning and doing work. It connects the air filter on the top and the engine block on the bottom, which is called the throat of the car engine. [0003] The traditional throttle valve basically adopts a high-pressure cast aluminum shell structure, which is heavy and does not conform to the development trend of lightweight automobile manufacturing. The market urgently needs to realize the application of the technology of replacing steel with plastic in the manufacture of throttle valves. Contents of the invention [0004] In order to solve the above problems, the present i...
