Description

Range-extending signal wheel for engine connecting rod

Technical Field

The invention relates to a signal wheel, in particular to a range-extending signal wheel of an engine connecting rod.

Background

The signal wheel is equivalent to the switch for controlling the engine, the design and the accurate control of the phase angle of the signal wheel play a vital role in the coordination work of each cylinder of the engine, the signal wheel provides a signal for the rotating speed sensor, the rotating speed sensor transmits the signal to the ECU (driving computer), and the ECU controls the engine to spray and ignite after receiving the signal. The signal wheel in the prior art basically reserves a central boss structure and a central shaft hole, and the reservation of the central boss structure and the central shaft hole can occupy a large part of the weight of the signal wheel, and the hollow structure is designed on the periphery of the central boss structure, so that the weight of the signal wheel is reduced very limitedly. In addition, the engine signal wheel is generally positioned by adopting a positioning pin, so that the signal wheel can deflect at a certain angle by taking the pin hole axis as the center, and after the signal wheel rotates at a high speed for a long time, the positioning pin is easily stressed and deformed due to the inertia effect of the signal wheel, so that the positioning accuracy is affected.

Disclosure of Invention

In order to solve the problems in the background technology, the invention provides an engine connecting rod range-extending signal wheel.

The invention adopts the following technical scheme: the utility model provides an engine connecting rod increases journey signal wheel, includes ring gear, three hard rubber outer loop, three hard rubber inner loop, three bolt collar, three connecting rib, three installation department and a plurality of dogtooth, the outer periphery of ring gear is fixed with a plurality of dogteeth along its circumference, and the inner periphery of ring gear is fixed with three installation department along its circumference, every the terminal surface of installation department all is equipped with the mounting hole, all is fixed with a connecting rib between every two adjacent installation departments, ring gear, three connecting rib, three installation department and a plurality of dogtooth integrative casting, every the inside wall of mounting hole respectively with the outer periphery fixed connection of corresponding hard rubber outer loop, every the inner periphery of hard rubber outer loop is all fixed with a plurality of dogteeth along its circumference equiangular, the outer periphery of every hard rubber inner loop is fixed with a plurality of dogteeth two along its circumference, and three hard rubber inner loop is connected with corresponding hard rubber meshing respectively.

Compared with the prior art, the invention has the beneficial effects that: the invention omits the middle boss structure and the central shaft hole structure, changes the middle boss structure and the central shaft hole structure into the combination of the gear ring, the mounting part and the connecting rib, and has simpler structure and lighter weight; meanwhile, a hard rubber outer ring and a hard rubber inner ring which are meshed with each other are arranged between the mounting hole and the bolt mounting ring, certain elasticity exists in the hard rubber, and when the stress is overlarge, the hard rubber is not easy to damage, and then the deformation of a positioning pin of the signal wheel caused by the inertia of the signal wheel is avoided, and the positioning accuracy is guaranteed.
