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
The present invention relates to a kind of rotational position signal dish that is used for engine cam.
Background technique
The operation conditions that modern motor generally adopts electronic fuel injection system to manage motor by computer (ECU) because of the requirement of environmental protection and Economy is obtained the running state of camshaft thus exactly according to the working principle needs of motor.The common practice of available engine is: a cover position signal generating means is set in the rear end of motor also rotates with camshaft so that the position signal that rotates (signal is picked up by special-purpose electromagnetic signal sensor) with the terminal mechanical connection of camshaft with coupling shaft.Because engine operation makes inner produce higher temperature and vibrations, need tight isolated for the security of operation inside and outside that guarantees motor simultaneously, original like this camshaft signal generating means must be provided with firm external form and fixing device so that combine with engine body is firm, also need design simultaneously and installs air locking so that isolated motor inside and outside is not leaked the engine interior Lubricants and outside impurity can not enter.Owing to above reason available engine camshaft signal generating means is comparatively accurate, complicated, all higher to machining and assembling and setting technological requirement, bring the possibility that fault produces in cost of production rising and the actual using process to increase.
In addition, the 8A type petrol engine that Toyota Company (TOYOTA) produces in Chinese Tianjin, be provided with special signal generator for obtaining camshaft-position signal in the motor rear end, generator is inner to be connected so that rotate with camshaft with the camshaft tail end for signal teeth and with transmission shaft, for the fixed signal tooth be provided with special shell with support so that is connected, for the sealing of maintenance motor also is provided with special seal ring with motor is stable.The component number of motor is increased, therefore also increased the weight and the cost of motor, also increased the possibility that breakdown in the motor produces in actual use.
Summary of the invention
For this reason, the invention provides a kind of engine camshaft rotating position signal disc that overcomes original complexity.
Engine camshaft rotating position signal disc of the present invention is fixedly mounted on engine cam or the camshaft actuated wheel, described signal panel are circular, it has first surface and second surface, and described first surface and second surface are axial at a distance of certain distance along described signal panel.
Described second surface is that external diameter is the semicircular ring surface of signal panel outer rim.
The outer rim of described signal panel has positioning hole.
Distance vertically between first surface and the second surface is 1-10mm.
Described signal panel thickness is 0.5～8mm.
Signal panel of the present invention are guaranteeing under the prerequisite that the engine cam shaft position signal is accurately produced and picked up, complexity, assembling and setting technological requirement and the more high shortcoming of cost of original device have been overcome, adopt the sheetmetal impact briquetting, accurate positioning hole and camshaft and camshaft actuated belt wheel are set accurately locate, thereby thereby make camshaft rotate the generation position signal together.Save original sealing and fixing device owing to being directly installed on engine interior, simplified simultaneously correspondingly valve mechanism cover and the structure of cylinder head, separate unit motor cost can reduce weight saving.Unless the problem of material can thoroughly be got rid of the fault that produces in the using process, improved the reliability and the Economy of motor.

Fig. 3 A is installed in plan view on the driving wheel for signal panel of the present invention, and Fig. 3 B is the sectional view along B-B line among Fig. 3 A;
Embodiment
Fig. 1 is a signal panel structural representation of the present invention, it is made by the circular metal thin plate, making circular plate is the boundary with the diameter, wherein the external diameter on half is the semicircular ring part of circular metal plate outer rim, by the direction punching press of edge with circular metal thin plate parallel to an axis, thereby making the surface of semicircular ring part is second surface 4, with the surface of circular metal thin plate remaining part be first surface 3 vertically at a distance of certain distance, first surface 3 and second surface 4 are preferably all with described axial vertical.The rotating center hole 1 that is positioned at signal panel 6 centers is passed for the camshaft (not shown), and signal panel 6 are fixedlyed connected with camshaft, signal panel 6 outer rims are provided with positioning hole 2, thereby the fixing bolt that makes camshaft actuated wheel 5 passes positioning hole 2 and makes signal panel 6 and camshaft actuated wheel 5 location, and signal panel 6 can correctly reflect the pivotal position of camshaft and camshaft actuated wheel like this.Signal panel 6 also can not have rotating center hole 1, decide according to the different mounting points of signal panel 6.
Signal panel 6 are that 0.5～8mm sheetmetal is manufactured by thickness, and the thickness degree can be according to the requirement decision of concrete engine structure to its intensity.
Signal panel 6 among Fig. 2 A are circular, and the distance between first surface 3, the second surface 4 is 1-10mm preferably.
Shown in Fig. 3 A, 3B, signal panel 6 directly have been placed in engine interior, determine correct position relation by positioning hole 2 and camshaft, utilize the fixing bolt of original camshaft actuated wheel that signal panel are fixed on the camshaft actuated wheel 5, first surface 3, the second surface 4 that is interlaced by signal panel along with the rotation of camshaft produces the signal that can be accepted by electromagnetic sensor, so just realized the generation of camshaft-position signal and picks up and give Engine ECU to control the normal operation of motor by sensor passes.Preferred signals disk center axis and camshaft central axes during installation.
Signal panel 6 can not be circular but the sheetmetal of other smooth circular curve is stamped to form by its outer rim yet, at this moment, the outer rim of signal panel 3 is projected as smooth circular curve, and the shape of second surface also can be other shape of removing above-mentioned semi-round ring shape, as: semi-circular, circular, square etc.
Positioning hole can arbitrarily be arranged on the arbitrary position of signal panel as long as can guarantee to determine the correct relation of signal panel and camshaft location.
Because signal panel of the present invention are directly taken turns Placement and are positioned in engine interior by bolt and camshaft actuated, component such as transmission shaft, shell, support and seal ring had so both been omitted, alleviated the weight of motor, reduced the cost of motor, also reduce the possibility of the corresponding operation troubles generation of motor, improved the reliability of motor.
