Abstract

The invention relates to a non-contact intelligent electronic throttle and belongs to an intelligent electronic throttle control assembly for an engine of an automobile. The throttle comprises a sensor structure, a sensor shaft driving mechanism controlled by a throttle pedal, and a singlechip main controller. The sensor structure is as follows: two magnets are fixed on a shaft of the sensor; two linear hall sensors perpendicular to each other are fixed on a circuit board, the circuit board is fixed on a body; and the hall sensors are positioned within a uniform magnetic field generated by the two magnets. The sensor shaft driving mechanism controlled by the throttle pedal is as follows: a pressure pad is arranged on the body, an intermediate shaft is arranged in and suspended by a limit notch of the body and an opening of the pressure pad and is provided with a spring clip, a limit plate and a resetting spring; one end of the resetting spring is connected with the body, while the other end is fixed on the limit plate; when put in place, the resetting spring generates a restoring force; one end, extending out of the body, of the intermediate shaft is connected with the pedal, while the other end is connected with the shaft of the sensor. The throttle has the characteristics of long service life, high precision, high reliability and intelligent control.

Description

technical field

[0001] The invention relates to an engine throttle control system, in particular, it belongs to the technical field of an electronic throttle control assembly of an automobile internal combustion engine. Background technique

[0002] At present, the accelerator system of the automobile internal combustion engine system is divided into two types: mechanical type and electronic type. The mechanical type uses a steel wire and a lever to connect with the throttle shaft. The driver pulls the steel wire by stepping on the accelerator to control the opening of the throttle and change the output power of the engine. The mechanical throttle is mainly used for the mechanical throttle. The main problem is that it is connected by a steel wire, which is easy to wear and the control is not precise. Now the engine control system is gradually replacing it with an electronic throttle.

[0003] At present, most electronic throttles use contact angle sensors, the principle of ...
