Detailed Description

The present invention will be described in detail with reference to the accompanying drawings 1-5 and the detailed description thereof.

Please refer to fig. 1, fig. 2 and fig. 5, the embodiment of the present invention provides a multifunctional engine timing structure, which includes a flywheel housing 1 and a flywheel 2 installed in the flywheel housing 1. The bottom surface of the circumference of the flywheel shell 1 is provided with a pointer surface 3 and flywheel shell barring holes 4, the circumference of the flywheel 2 is provided with flywheel panel barring holes 5 at intervals, the flywheel shell barring holes 4 correspond to the flywheel panel barring holes 5, and the distance between every two adjacent flywheel panel barring holes 5 is smaller than the length of the flywheel shell barring holes 4. The circumferential surface of the flywheel 2 is also engraved with a pointer line 6, and the pointer line 6 corresponds to the position of the pointer surface 3.

In the processes of engine assembly, maintenance and the like, a hard rod is taken to be inserted into a flywheel barring hole 5 of a flywheel 2 through a flywheel housing barring hole 4, the flywheel barring hole 5 is laterally slid to the right side from the left side of the flywheel housing barring hole 4, the distance between every two adjacent flywheel barring holes 5 is smaller than the length of the flywheel housing barring hole 4, the hard rod can be pulled out of the flywheel barring hole 5 on the right side of the flywheel housing barring hole 4, the flywheel barring hole 5 on the left side of the flywheel housing barring hole 4 slides to the right side continuously through the hard rod, the hard rod is repeatedly used for prying the flywheel 2 to rotate back and forth in the mode until the pointer line 6 of the flywheel 2 is overlapped with any position of the pointer surface 3 of the flywheel housing 1, the flywheel 2 stops sliding, and engine timing check can be completed.

Further, the length of the flywheel housing barring hole 4 extends along the circumferential direction of the flywheel 2, namely, the flywheel housing barring hole 4 is transversely arranged. The diameter of the flywheel barring hole 5 is smaller than the width of the flywheel housing barring hole 4, so that the hard barring rod is greatly convenient to pry the flywheel 2 to rotate back and forth. The length directions of the pointer surface 3 and the turning hole 4 of the flywheel housing are mutually vertical. The pointer surface 3 can be arranged on the top surface of the turning hole 4 of the flywheel housing and also can be arranged on the bottom surface of the turning hole 4 of the flywheel housing.

Further, referring to fig. 4, an end of the pointer surface 3 away from the flywheel housing barring hole 4 is cast with a tool withdrawal groove 7.

Further, referring to fig. 1 and 2, the pointer surface 3 is parallel to the engine centerline. The pointer surface 3 and the turning hole 4 of the flywheel shell further serve as an observation window of the flywheel 2, so that parts are saved, and the size of the engine is reduced. The pointer line 6 is also parallel to the central line of the engine, so that the condition that the pointer line 6 is superposed with the pointer surface 3 can be conveniently and quickly identified.

Further, the pointer surface 3 and the flywheel housing turning hole 4 are close to the bottom end of the flywheel housing 1, and the requirement for water drainage of the inner cavity of the flywheel housing 1 is met.

Further, referring to fig. 3, the circumferential surfaces of the flywheel housing 1 except the pointer surface 3 are casting surfaces, so that the production cost is reduced.

Although the invention has been described in detail and with reference to specific embodiments thereof, it will be apparent to one skilled in the art that modifications and improvements can be made thereto. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
