Invention content
The present invention provides a kind of gasoline engine crank rotating speed signal disc, can solve in the existing punching press tablet bent axle of solution
The existing installation cooperation precision of rotating speed signal disc is low, and disk body poor rigidity, signal teeth is easy to be hit curved problem and manufacturing procedure
It is more, the high problem of manufacturing cost.
A kind of gasoline engine crank rotating speed signal disc of the present invention, including disk body are equipped with peace in the centre of disk body
Location hole is filled, sets that there are three non-uniformly distributed screw mounting holes on the circumference concentric with mounting-positioning holes on disk body, on disk body
Equipped with speed of crankshaft signal acquisition structure；It is set on the circle of the mounting-positioning holes arc-shaped recessed there are three equidistantly distributing
Slot is equipped with dynamic balancing slot in the bottom of one circular groove.
Further, the speed of crankshaft signal acquisition structure includes the flange for the circumferential periphery for being located at disk body, the flange
It is equipped with several signal teeths and a hypodontia window；The top of several signal teeths is connected, between adjacent signal teeth
Form window.
Further, it is respectively equipped with small convex flat platform at the edge of described three non-uniformly distributed screw mounting holes.
Further, it is equipped with continuous reinforcing rib in the circumferential edges of the disk body.
Further, the height of the small convex flat platform at the edge of the screw mounting hole is 0.15mm to 0.25mm.
Further, the disk angle of the flange of the disk body and disk body is 90 °.
The present invention has the following advantages：
（1）Since the periphery of the mounting-positioning holes at disk body center is there are three circular groove, make mounting-positioning holes with it is bent
The axle journal of axis forms three sections of cooperations, to while ensureing to coordinate precision at this three sections, reduce the abrasion of punch, drops
The low weight of signal panels.
（2）Due to dynamic balancing slot and punching shaping of mounting-positioning holes and circular groove, reduces blank operation, carry
High manufacturing efficiency.
（3）Since disk body outer circle side area stamps out reinforcing rib, the rigidity of disk body is improved, and improve collecting crankshaft
The reliability of tach signal.
（4）Since the bolt hole periphery of disk body and bent axle contact surface stamps out 0.2mm（Millimeter）The small convex flat platform of left and right, and
Small convex flat table top product is smaller, can be good at ensureing flatness, improves the quality coordinated with bent axle.
（5）Since the end of signal teeth is connected, window-like is formed between adjacent signals tooth, can not only enhance entire disk body
Rigidity, increase reliability, and can prevent transport and assembling process in caused by collision signal teeth deform.
（6）It is simple in structure, quality is small, can be one time punching molded, it is at low cost, it is easy for installation, be suitable for various gasoline engine.

Specific implementation mode
Below according to Figure of description, the invention will be further described：
Referring to Fig. 2, Fig. 3 and Fig. 4, a kind of gasoline engine crank rotating speed signal disc, including disk body 16, in disk body
Center portion position is equipped with mounting-positioning holes 11, sets that there are three non-uniformly distributed on the circumference concentric with mounting-positioning holes on disk body（To fill
Timing mistake proofing, edentulous site has certain angle requirement with bent axle after general assembly）Screw mounting hole 14, be equipped on disk body
Speed of crankshaft signal acquisition structure, substantive distinguishing features outstanding are：There are three being set on the circle of the mounting-positioning holes 11 etc.
The circular groove 18 of range distribution is equipped with dynamic balancing slot 12 in the bottom of one circular groove.In mounting-positioning holes
Circumference set there are three the circular groove that equidistantly distributes, so that the axle journal of mounting-positioning holes and bent axle is formed three sections of cooperations, with
Cooperation precision is improved, while the abrasion of punch can be reduced, that is, mitigates the weight of disk body.Dynamic balancing slot and mounting-positioning holes and circular arc
Punching shaping of connected in star improves to reduce blank operation and manufactures efficiency.
The speed of crankshaft signal acquisition structure includes the flange for the circumferential periphery for being located at disk body 16, if on the flange
Dry signal teeth 15 and a hypodontia window 13；The top of several signal teeths 15 is connected, shape between adjacent signal teeth
At window.In this way, can not only enhance the rigidity of entire disk body, but also can prevent in transport and assembling process because collision is drawn
The signal teeth deformation risen, ensures that collecting crankshaft tach signal is accurate.It is defeated that hypodontia window 13 cuts the crankshaft rotational speed sensor magnetic line of force
The induced voltage different from of the induced voltage gone out and the cutting crankshaft rotational speed sensor magnetic line of force output of remaining signal teeth 15, is used for
ECU judges the crank rotation number of turns.ECU is translated into speed of crankshaft signal by analyzing induced voltage signal.
It is respectively equipped with small convex flat platform 19 at the edge of three equidistant screw mounting holes 14.Due to small convex flat table top
Product is smaller, can ensure flatness well, can improve and bent axle fit quality.
It is equipped with continuous reinforcing rib 17 in the circumferential edges of the disk body 16, to improve the rigidity of disk body.
The height of the small convex flat platform 19 at the edge of the screw mounting hole 14 is 0.15mm（Millimeter）To 0.25mm（Millimeter）.
The flange of the disk body 16 and the disk angle of disk body are 90 °.
Referring to Fig. 5 and Fig. 6, the mounting-positioning holes 11 of disk body 16 and the axle journal formation precision-fit of bent axle 21, the three of disk body
A small convex flat platform with the mounting surface of bent axle is corresponding contacts, and it is urgent by three disk body screws 20.
