Description

Technical Field

[0001] The present invention relates to the technical field of engine signal faults, and particularly to a flywheel integrated with a crankshaft signal hole and a fault handling method. Background Art

[0002] The flywheel is an important part of the engine. Its main function is to store the energy of the power stroke to overcome resistance in other strokes, complete the engine's working cycle, make the rotational angular velocity and output torque of the crankshaft as uniform as possible, and improve the engine's ability to overcome short-term overloads. Currently, some engines need to add a position signal disk on the crankshaft to obtain the crankshaft position signal through a sensor.

[0003] When applied in the fields of agricultural machinery such as rice transplanters and tractors, the signal holes are easily blocked by silt, affecting the crankshaft signal strength and causing the crankshaft signals to be out of sync.

[0004] The existing patent document CN215257618U discloses a flywheel with signal holes, which has a circle of signal holes arranged on the outer circle of the flywheel body. However, these signal holes are blind holes, and when applied to agricultural machinery, the signal holes will still be blocked by silt, affecting the crankshaft signal and misissuing fault signals.

[0005] The disclosure of the above background art content is only used to assist in understanding the concept and technical solution of the present invention, and it does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background art should not be used to evaluate the novelty and inventiveness of this application. Summary of the Invention

[0006] The main purpose of the present invention is to propose a flywheel with vertically penetrating signal holes. When the holes are blocked by silt and a fault is reported, by stopping the machine and using inertia to make the rotational speeds of the flywheel and the silt out of sync, the silt is thrown out of the signal holes to achieve the function of automatic silt cleaning. The present invention also additionally proposes a processing method for solving crankshaft signal faults.

[0007] To this end, the present invention proposes a flywheel integrated with a crankshaft signal hole and a fault handling method.

[0008] Preferably, the present invention may further have the following technical features:

[0009] A flywheel integrated with a crankshaft signal hole includes a flywheel and a gear ring. The flywheel and the gear ring are coaxial. The front side of the flywheel is provided with a gear ring, and the rear side is provided with a circular ring. A plurality of radial signal holes are formed on the side surface of the circular ring; the signal holes are through holes that penetrate the inner side and the outer side of the circular ring.

[0010] Furthermore, the length of the signal holes is 5 - 7 mm.

[0011] Further, a plurality of weight removal holes are provided on the flywheel.

[0012] A method for processing a crankshaft signal fault of a flywheel as described above includes the following steps:

[0013] (1) The vehicle in operation reports a crankshaft signal fault code.

[0014] (2) Obtain the current vehicle operation environment and determine the possibility of the flywheel contacting sludge.

[0015] (3) Control the engine to return to the first idle speed and then stop. After the stop time reaches the first preset time, restart the engine.

[0016] (4) If the crankshaft signal fault code is cleared, continue with field operations.

[0017] Further, the first idle speed is 1100 - 1250 rpm.

[0018] Further, the first idle speed is 1200 rpm.

[0019] Further, the first preset time is 10 - 20S.

[0020] Further, the first preset time is 15S.

[0021] The beneficial effects of the present invention compared with the prior art include: By making the signal hole a perforated hole, when sludge enters the signal hole, it can flow out from the other side of the signal hole, improving the sludge passability, reducing the risk of sludge blocking the signal hole, and reducing the number of false alarms of crankshaft signal faults. By stopping and restarting the vehicle at a certain idle speed, the sludge in the signal hole can be automatically cleared, and the operation method is simple and easy to implement.

[0023] Figure 2 is a control flow chart of the method of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope of the present invention and its applications.

[0025] Referring to the following drawings, non - restrictive and non - exclusive embodiments will be described, where like reference numerals represent like components, unless otherwise specifically stated.

[0026] As Figure 1A flywheel integrated with a crankshaft signal hole as shown, comprising a flywheel 1 and a ring gear 2. The flywheel 1 and the ring gear 2 are coaxial. The ring gear 2 is provided on the front side of the flywheel 1, and a ring 5 is provided on the rear side. A plurality of radial signal holes 3 are formed on the side surface of the ring 5. The signal hole 3 is a circular through-hole, which penetrates the inner side and the outer side of the ring 5. Preferably, the length of the signal hole 3 is 5-7 mm, and the length of the signal hole 3 is equal to the thickness of the ring 5. And a plurality of balancing holes 4 are also provided on the flywheel 1. The signal holes of the traditional flywheel are blind holes, which are prone to mud accumulation, resulting in the influence on the signal strength and frequent occurrence of crankshaft signal failures. By making the signal hole 3 a through-hole, when silt enters the signal hole 3, it can flow out from the other side of the signal hole 3, improving the permeability of the silt, reducing the risk of the signal hole being blocked by silt, and reducing the number of false alarms of crankshaft signal failures.

[0027] Combined with Figure 2 , a method for processing crankshaft signal failures of a flywheel as described above includes the following steps:

[0028] (1) The vehicle in operation reports a crankshaft signal fault code; specifically, an alarm fault code is sent through the vehicle instrument panel.

[0029] (2) Obtain the current vehicle operation environment and determine the possibility of the flywheel contacting silt; specifically, the driver can visually observe the operation environment. For example, if the driver judges that there is a lot of silt in the current operation environment, especially when it can be judged that the vehicle is in a stuck state, then it can be inferred that the flywheel has the possibility of contacting silt, and then a fault handling method of clearing the silt by stopping the machine and using inertia can be adopted.

[0030] (3) Control the engine to return to the first idle speed and then stop. After the stop time reaches the first preset time, restart the engine; the first idle speed is 1100-1250 rpm, preferably 1200 rpm. The first preset time is 10-20 S, preferably 15 S.

[0031] (4) If the crankshaft signal fault code is cleared, continue with the field operation; if the crankshaft signal fault is not cleared, send the vehicle for repair.

[0032] After reporting the crankshaft signal fault, by pulling the throttle to the minimum position, the engine returns to the idle speed of 1200 revolutions per minute, and then stops; use the speed difference generated by the engine stop to throw out the silt blocking the signal hole. After stopping for more than ten seconds, restart the engine again, and the inertia of the flywheel can be used again during the starting process to further throw out the silt.

[0033] The present invention designs the flywheel as an outer ring structure, and at the same time designs the signal hole as a perforated structure. In this way, when it is determined that the signal hole is blocked by silt, the flywheel can be stopped, and the inertia is used to make the rotational speeds of the flywheel and the silt out of sync, so as to throw the silt out of the signal hole, realizing the automatic silt cleaning function, and then quickly eliminating the false alarm fault of the crankshaft signal.

[0034] Those skilled in the art will recognize that numerous variations to the above description are possible, so the embodiments and drawings are only used to describe one or more specific embodiments.

[0035] Although the exemplary embodiments that are regarded as the present invention have been described and recited, those skilled in the art will understand that various changes and substitutions can be made thereto without departing from the spirit of the present invention. Additionally, many modifications can be made to adapt a particular situation to the teachings of the present invention without departing from the central concept described herein.
