Embodiment Construction

[0014] figure 1 It is a schematic diagram of the structure of the signal plate of the present invention, which is made of a circular metal sheet, so that the circular plate is bounded by the diameter, and the outer diameter of half of it is the semicircular part of the outer edge of the circular metal plate, which is along the circular The thin metal plate is punched in a direction parallel to the axial direction, so that the surface of the semi-circular ring part, that is, the second surface 4, is at a certain distance from the surface of the rest of the circular metal sheet, that is, the first surface 3 in the axial direction. Both surfaces 4 are preferably perpendicular to the axis. The rotation center hole 1 located at the center of the signal disc 6 is used for the passage of the camshaft (not shown), and the signal disc 6 is fixedly connected with the camshaft. The bolt passes through the positioning hole 2 so that the signal plate 6 and the camshaft drive wheel 5 are p...

Abstract

The invention provides a turning position signal panel of the engine camshaft which is installed on the engine camshaft or the camshaft driving wheel. The signal panel is round and has the first surface and the second surface which are far from some distance along the signal panel axis. The out edge of the signal panel is set with the locating hole, so it can be set in the engine to decrease the weight and cost, also it can decrease the accident capability.

Description

technical field [0001] The invention relates to a rotational position signaling disc for an engine camshaft. Background technique [0002] Due to the requirements of environmental protection and economy, modern engines generally use electronically controlled fuel injection systems to manage the operating conditions of the engine by a computer (ECU), so that the operating conditions of the camshaft need to be accurately obtained according to the working principle of the engine. The common practice of existing engine is: a set of position signal generator is set at the rear end of engine and is mechanically connected with camshaft end with connecting shaft and rotates with camshaft so as to produce the position signal of rotation (signal is picked up by special electromagnetic signal sensor). Due to the high temperature and vibration inside due to the operation of the engine, at the same time, to ensure the safe operation of the engine, the inside and outside must be tightly i...
