Technical Field
[0001] The utility model belongs to the technical field of engines and relates to engine parts, in particular to an independent transfer case of an engine. Background Art
[0002] In the engine field, in addition to the flywheel output, some models also require a power output port to drive the customer's steering pump or hydraulic pump and other components.
[0003] The transfer cases on existing engines are all integrated on the engines, that is, the transfer case 1' is fixed on the engine body 2' by several bolts, the oil passage holes on the engine body are connected with the oil passage holes of the transfer case, and the lubricating oil flows from the engine body to the transfer case through the connected oil passage holes to lubricate the gears and bearings.
[0004] Although this structure meets the engine's power requirements for the entire vehicle,: (1) the transfer case is limited by the structure of other engine parts; (2) the transfer case and the engine share a lubrication system, which can cause problems such as insufficient engine oil pressure. Utility Model Content
[0005] The utility model aims to provide an independent transfer case structure, which can be assembled, transported, lubricated, tested and the like independently of an engine.
[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model provides an engine-independent transfer case, including a transfer case that can be installed on the engine, the transfer case including a coupling that can be connected to the flywheel of the engine, a gear shaft connected to the coupling, a rear-end component connected to the gear shaft, an idler shaft connected to the gear shaft, and a transfer case power output port connected to the idler shaft.
[0007] Preferably, the transfer case comprises a connection plate connectable to a flywheel housing of the engine, and the coupling is arranged on the inner periphery of the connection plate.
[0008] Preferably, the reserved mounting hole of the flywheel housing is a SAE standard interface, and the mounting hole of the connecting plate is also a SAE standard interface.
[0009] Preferably, the connecting plate may be connected to the flywheel housing by a circle of second bolts.
[0010] Preferably, the transfer case is provided with a refueling port on the top and an oil drain port on the bottom, and the lubricating oil can be independently filled and / or drained.
[0011] Preferably, the coupling may be provided with a circle of first bolts connected to the flywheel.
[0012] In summary, the utility model includes the following beneficial technical effects:
[0013] (1) The coupling isolates the impact of the transfer case output on the engine, and the engine reliability is high;
[0014] (2) The transfer case structure design is not limited by the engine structure and can meet the needs of users with different power output capacities and different numbers of power output ports, with high matching adaptability;
[0015] (3) The transfer case gear train lubrication system is independent and separated from the engine lubrication system;
[0016] (4) The transfer case can be assembled separately and then installed on the engine as a whole, saving production line time;
[0017] (5) The transfer case can be tested independently by inputting power through the transfer case gear shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model embodiment discloses an independent transfer case for an engine.
[0024] The engine power is transmitted from the flywheel 1 to the transfer case input gear shaft 8 through the coupling 4. The power can be directly transmitted from the gear shaft 8 to the rear-end components, or it can be transmitted from the gear shaft 8 to the transfer case power output port through the idler shaft 6. The transfer case can be provided with different numbers of power output ports according to different needs.
[0025] The transfer case is mainly composed of a connecting plate 3, a coupling 4 and a transfer case body 5 (including an external housing and internal gears, etc.). The transfer case reserves the required power output port at the rear end of the transfer case body 5 as required. The top of the transfer case body 5 is provided with a refueling port, and the bottom is provided with an oil drain port, which can be independently filled / drained with lubricating oil.
[0026] The coordination between the transfer case and the engine includes two steps. The first step is that the coupling 4 on the transfer case is coordinated with the flywheel 1 on the engine and fixed with a circle of evenly distributed first bolts 7. The second step is that the connecting plate 3 on the transfer case is coordinated with the flywheel housing 2 on the engine and fixed with a circle of evenly distributed second bolts 9.
[0027] The reserved mounting hole of the flywheel housing 2 is a SAE standard interface, and the connecting plate 3 is also a SAE standard interface. The SAE standard interface allows the design of the transfer case to be free from the restrictions of the engine structure. Since the transfer case is fixed to the engine only by the above two steps, and other engine parts are not related to the transfer case, the transfer case can be assembled separately, packaged and transported independently; and since the transfer case is equipped with a separate oil filling port and oil drain port, the lubrication of the transfer case does not occupy the engine lubrication system, which allows the transfer case to be tested and verified separately.
[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
