Description

Technical Field

[0001] This utility model relates to the technical field of diesel engine flywheel equipment, and more specifically, to a diesel engine flywheel assembly with a signal disc. Background Technology

[0002] A diesel engine flywheel is a heavy-duty metal disc with a large moment of inertia, mounted at the output end of the engine crankshaft. Its main function is to store and release energy. Since a diesel engine only generates power during the power stroke, while the intake, compression, and exhaust strokes consume energy, the flywheel uses its inertia to store some of the kinetic energy absorbed during the power stroke and releases it during the non-power strokes. This effectively smooths out the fluctuations in crankshaft rotation, making the engine run more smoothly and evenly. Additionally, the outer edge of the flywheel is usually equipped with a gear ring for engaging with the starter motor to start the engine, and its rear end face serves as a friction surface, connecting with the driving part of the clutch to transmit power to the transmission system.

[0003] A diesel engine signal disc is a metal geared disc fixed to the crankshaft or camshaft and rotating synchronously with the engine speed. Its outer edge or end face is typically engraved with a specially arranged array of notches or teeth. Its core function is to serve as the trigger source for the position sensors in the engine control system. As the signal disc rotates, the backlash on its teeth periodically sweeps past the crankshaft or camshaft position sensors, cutting magnetic lines of force or altering the magnetic field, thereby generating continuously changing electrical pulse signals. By accurately reading the frequency and phase of these pulse signals, the electronic control unit (ECU) can determine the precise engine speed, crankshaft angle, and piston top dead center position in real time, thus achieving high-precision control of fuel injection timing and quantity, ensuring efficient and stable engine operation.

[0004] The flywheel and signal disc are mostly fixed together using bolts. During installation, the operator needs to precisely align the bolt holes on the signal disc with the threaded holes on the flywheel. Because the flywheel and signal disc themselves have considerable weight and size, and there are usually more than one bolt hole, the operator often needs to use one hand or a temporary tool to support the signal disc while simultaneously overcoming its own weight to maintain a perfect fit and alignment with the flywheel. Then, the other hand is used to insert and tighten the bolts. This process is not only physically demanding but also extremely labor-intensive. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a diesel engine flywheel assembly with a signal disc, which can pre-fix the flywheel body and the signal disc body, achieving quick and accurate pre-positioning of the flywheel body and the signal disc body before fixed installation. This eliminates the need for operators to laboriously hold or press the two components, requiring only the final fixing operation, thus reducing the difficulty and labor intensity of operation.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution:

[0009] A diesel engine flywheel assembly with a signal disc, comprising:

[0010] The flywheel body has two first arc-shaped blocks fixedly connected to one side of its outer surface;

[0011] A signal disk body, wherein the signal disk body is disposed on one outer surface of the flywheel body; and

[0012] Two sets of locking mechanisms are provided. Each locking mechanism includes a locking frame, a side box, a second arc-shaped block, a connecting plate, and two return springs. The locking frame is fixedly connected to the inner wall of one side of the signal disk body. The side box is fixedly connected to the outer surface of one side of the locking frame. The second arc-shaped block slides through the inner wall of one side of the locking frame. The connecting plate is fixedly connected to the outer surface of one side of the second arc-shaped block. Both return springs are fixedly connected between the side box and the connecting plate.

[0013] As a preferred embodiment of this utility model, the snap-fit ​​mechanism further includes two limiting rods, both of which are fixedly connected between the snap-fit ​​frame and the side connecting box, and the connecting plate is slidably sleeved on the two limiting rods.

[0014] In a preferred embodiment of this utility model, each of the limiting rods is made of stainless steel.

[0015] As a preferred embodiment of this utility model, each set of the snap-fit ​​mechanism also includes a lever, each lever slidingly penetrating one side inner wall of the corresponding side junction box, and two sliding groove holes are opened on one side outer surface of the signal disk body, and the two levers respectively slide through the two sliding groove holes.

[0016] As a preferred embodiment of the present invention, the locking mechanism further includes a lever block, which is fixedly connected to one end of the lever.

[0017] As a preferred embodiment of this utility model, two positioning inner tubes are fixedly connected to one outer surface of the flywheel body, and two positioning sleeves are fixedly connected to one inner wall of the signal disk body.

[0018] 3. Beneficial Effects

[0019] Compared with the prior art, this utility model provides a diesel engine flywheel assembly with a signal disc, which has the following advantages:

[0020] This diesel engine flywheel assembly with a signal disc, when installing the signal disc body onto the flywheel body, involves inserting two first arc-shaped blocks into two locking frames. As each first arc-shaped block moves into its corresponding locking frame, its arc surface contacts the arc surface of a corresponding second arc-shaped block. The two second arc-shaped blocks are then pushed away from the locking frames. When the flywheel body and the signal disc body are in contact, the restoring force of two return springs inside each side box acts on the corresponding connecting plate, causing the two connecting plates to move the two second arc-shaped blocks into the two locking frames respectively. This allows the two second arc-shaped blocks to lock the two first arc-shaped blocks into the two locking frames, thus pre-fixing the flywheel body and the signal disc body. This achieves rapid and accurate pre-positioning before fixed installation of the flywheel body and the signal disc body, eliminating the need for operators to forcefully hold or press the two components; only the final fixing operation is required, reducing operational difficulty and labor intensity.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Example:

[0031] Please see Figures 1-6 A diesel engine flywheel assembly with a signal disc, comprising:

[0032] The flywheel body 1 has two first arc-shaped blocks 4 fixedly connected to one side of its outer surface;

[0033] Signal disc body 2, the signal disc body 2 is disposed on one outer surface of the flywheel body 1; and

[0034] Two sets of locking mechanisms 3 are provided. Each locking mechanism 3 includes a locking frame 301, a side box 302, a second arc surface block 303, a connecting plate 304, and two return springs 305. The locking frame 301 is fixedly connected to the inner wall of one side of the signal disk body 2. The side box 302 is fixedly connected to the outer surface of one side of the locking frame 301. The second arc surface block 303 slides through the inner wall of one side of the locking frame 301. The connecting plate 304 is fixedly connected to the outer surface of one side of the second arc surface block 303. Both return springs 305 are fixedly connected between the side box 302 and the connecting plate 304.

[0035] In a specific embodiment of this utility model, when the signal disk body 2 is installed on the flywheel body 1, two first arc-shaped blocks 4 are inserted into the two snap-fit ​​frames 301. During the movement of each first arc-shaped block 4 into the corresponding snap-fit ​​frame 301, the arc surface of each first arc-shaped block 4 contacts the arc surface of the corresponding second arc-shaped block 303. Then, the two second arc-shaped blocks 303 are pushed away from the interior of the snap-fit ​​frame 301. When the flywheel body 1 and the signal disk body 2 are in contact, the restoring force of the two return springs 305 inside each side connector 302 acts on... Corresponding to the connecting plate 304, the two connecting plates 304 drive the two second arc surface blocks 303 to move into the interior of the two snap-fit ​​frames 301 respectively, so that the two second arc surface blocks 303 snap the two first arc surface blocks 4 into the interior of the two snap-fit ​​frames 301, thereby pre-fixing the flywheel body 1 and the signal disk body 2, realizing quick and accurate pre-positioning before fixed installation between the flywheel body 1 and the signal disk body 2, without the operator having to hold or press the two parts, only needing to perform the final fixing operation, reducing the difficulty of operation and labor intensity.

[0036] Specifically, the snap-fit ​​mechanism 3 also includes two limiting rods 306, both of which are fixedly connected between the snap-fit ​​frame 301 and the side connection box 302, and the connecting plate 304 is slidably sleeved on the two limiting rods 306.

[0037] In this embodiment, the two limiting rods 306 inside each side box 302 ensure that the corresponding connecting plate 304 remains stable during movement and maintains a specific movement trajectory.

[0038] Specifically, each limit rod 306 is made of stainless steel.

[0039] In this embodiment, the limiting rod 306 is made of stainless steel, which has a smooth surface, low friction, high strength and durability.

[0040] Specifically, each set of latching mechanisms 3 also includes a lever 307, each lever 307 sliding through the inner wall of the corresponding side junction box 302. Two sliding slots are opened on the outer surface of one side of the signal disk body 2, and the two levers 307 slide through the two sliding slots respectively.

[0041] In this embodiment, the two levers 307 are used to manually control the movement of the two connecting plates 304, so that the two second arc blocks 303 are completely disengaged from the two locking frames 301, thereby ensuring that when the flywheel body 1 and the signal disk body 2 need to be separated, the two second arc blocks 303 do not block the two first arc blocks 4 from being removed from the two locking frames 301.

[0042] Specifically, the locking mechanism 3 also includes a lever 308, which is fixedly connected to one end of the lever 307.

[0043] In this embodiment, the two levers 308 facilitate the movement of the two levers 307.

[0044] Specifically, two positioning inner tubes 5 are fixedly connected to one side of the outer surface of the flywheel body 1, and two positioning sleeves 6 are fixedly connected to one side of the inner wall of the signal disk body 2.

[0045] In this embodiment, two positioning inner tubes 5 are inserted into two positioning sleeves 6 to achieve accurate positioning when the flywheel body 1 and the signal disk body 2 are docked.

[0046] Working principle: When the signal disk body 2 is installed on the flywheel body 1, two first arc-shaped blocks 4 are inserted into the two snap-fit ​​frames 301. As each first arc-shaped block 4 moves into the corresponding snap-fit ​​frame 301, the arc surface of each first arc-shaped block 4 contacts the arc surface of the corresponding second arc-shaped block 303. Then, the two second arc-shaped blocks 303 are pushed away from the inside of the snap-fit ​​frame 301. When the flywheel body 1 and the signal disk body 2 are in contact, the restoring force of the two return springs 305 inside each side connector box 302 acts on the corresponding connector. Plate 304 causes the two connecting plates 304 to move the two second arc surface blocks 303 into the interior of the two snap-fit ​​frames 301 respectively, so that the two second arc surface blocks 303 snap the two first arc surface blocks 4 into the interior of the two snap-fit ​​frames 301, thereby pre-fixing the flywheel body 1 and the signal disk body 2. This achieves quick and accurate pre-positioning before the fixed installation of the flywheel body 1 and the signal disk body 2, eliminating the need for operators to hold or press the two parts. Only the final fixing operation needs to be performed, reducing the difficulty of operation and labor intensity.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
