Abstract

The invention discloses a built-in hall-type neutral gear position sensor, comprising a neutral gear sensor subassembly and a magnetic subassembly. The neutral gear sensor subassembly comprises a shell and a hall element which is installed in the shell. The neutral gear sensor subassembly is fixed on a speed changer box body. The magnetic subassembly comprises a magnet element and an installing element. The magnetic subassembly is fixed on a shifting shaft through an elastic pin. The magnetic element and the hall element are oppositely arranged so as to ensure that the hall element can sense the magnetic line change of the magnet element in rotating process. The invention is featured with simple structure, installation convenience and long service life, reduces oil consumption and exhaust emission, and particularly applies the vehicles in the crowded road sections of the city.

Description

technical field [0001] The invention relates to the field of magnetoelectric sensors, in particular to a sensor for detecting whether an automobile transmission is in neutral or in gear. Background technique [0002] At present, the two major problems facing the sustainable development of the world's automobile industry are environmental pollution and oil shortage. Environmental protection and energy saving are an important development direction of automobile technology in the 21st century. an important indicator of . At present, there are more and more cars in the city, but the roads in the city are limited, and the engine is often in an idling state due to various conditions during driving. The traditional mechanical contact neutral switch has low service life and is difficult to install on the transmission, so a neutral sensor with long service life and simple installation is required. Frequent starting or idling of the engine will not only emit a large amount of harmfu...
