Abstract

The utility model relates to an engine rotation speed signal extracting device, comprising a crankshaft which is arranged inside an engine body. The engine rotation speed signal extracting device is characterized in that the device also comprises a signal disc and a sensor; the signal disc is arranged at the direct port at the end of the crankshaft; the sensor is arranged at the position of the engine body wall right facing to the signal disc. Therefore, by adopting the structure of the utility model, the signal out of the engine crankshaft can be directly extracted by the sensor which is arranged on the engine body, the phenomena such as signal offsetting and unstable signal which are caused by the conversion of vehicle types or installation errors are not generated; furthermore, the engine rotation speed signal extracting device has the advantages of simple structure, high universality, convenient installation and removal, high accuracy, etc.

Description

The engine rotational speed signal extraction apparatus
Technical field
The utility model relates to a kind of engine rotational speed signal extraction apparatus.
Background technique
Develop rapidly along with the motor industry, existing motor more and more develops towards electrification, especially be embodied on the control system of motor, two stop signals that the most basic parameter is exactly engine speed and motor that the electronic control system of motor need be extracted, therefore, the good signal source choose and stable signals collecting is most important.Existing motor generally adopts the rotating speed that extracts engine flywheel to the extraction of engine rotational speed signal, determine the rotating speed of motor, because engine application is in different automobile types or other equipment, the flywheel of motor also changes thereupon so, will cause whole signal extracting device to change like this, cause cost to improve; Also having a kind of structure in addition is to adopt sensor installation in the gear chamber of motor, extract the gear rotational speed in the gear chamber, determine the rotating speed of motor, owing in engine body, extract signal, the installing/dismounting inconvenience, also may interfere tach signal when moving simultaneously and extract,, also have deficiencies such as detecting and keep in repair inconvenience in addition to such an extent as to the signal that is extracted is inaccurate because of the vibrations that motor brings.
Summary of the invention
The utility model provides a kind of simple in structure, engine rotational speed signal extraction apparatus that degree of accuracy is high for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of engine rotational speed signal extraction apparatus, comprise the bent axle that is installed in the engine body, it is characterized in that: also comprise signal panel and sensor, signal panel are installed in the Zhi Kouchu of crankshaft end, on the engine body wall over against the position sensor installation of signal panel.
The utility model can also adopt following technical measures:
Described signal panel are packed on the straight mouth of crankshaft end by countersunk screw.
Advantage and the good effect that the utlity model has are: because signal panel are installed at straight mouthful of place of the bent axle in engine body, signal panel are solid on bent axle by countersunk screw, position over against signal panel on the engine body wall has through hole, sensor installation in through hole, sensor by bolton on engine body, by being installed in the direct tach signal that extracts from engine crankshaft of sensor on the engine body, can not produce like this because the conversion of vehicle and alignment error cause phenomenons such as the signal skew of extracting and instability, the utility model also has simple in structure in addition, the versatility height, easy installation and removal and extraction signal degree of accuracy advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A sectional view among Fig. 1.
Among the figure: 1, engine body; 1-1, through hole; 2, bent axle; Straight mouthful of 2-1, bent axle; 3, signal panel; 4, countersunk screw; 5, sensor.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, signal panel 3 are installed at straight mouthful of 2-1 place of the bent axle 2 in engine body 1, it is solid on bent axle 2 that signal panel logical 3 are crossed countersunk screw 4, position over against signal panel on engine body 1 wall has through hole 1-1, sensor installation 5 in through hole 1-1, sensor is fastened on the engine body 1 by bolt 6, directly extract from the engine crankshaft tach signal by the sensor that is installed on the engine body, can not produce like this because the conversion of vehicle and alignment error cause phenomenons such as the signal skew of extracting and instability, the utility model also has simple in structure in addition, the versatility height, the degree of accuracy advantages of higher of easy installation and removal and extraction signal.
