Technical Field
[0001] The utility model relates to the technical field of transfer cases, in particular to a transfer case flywheel housing. Background Technique
[0002] The so-called transfer case is a device that distributes the power of the engine. It can output power to the rear axle or output power to the front / rear axles simultaneously. As a key assembly of the transmission system, the automotive transfer case is used to distribute the torque of the transmission system to meet the different traction requirements of the vehicle under different working conditions. The flywheel housing is installed between the engine and the transmission, externally connected to the crankcase, starter, and oil pan, and internally equipped with a flywheel assembly, playing the role of connecting the body, protection, and carrier. When the existing transfer case works, since the flywheel housing mainly realizes the effective connection between the engine and the transmission, different parts of the flywheel housing will be subjected to more vibrations. After long-term operation, the flywheel housing is easily damaged, and the service life of the flywheel housing is relatively short. Moreover, the flywheel housing mainly relies on its own natural heat dissipation, and the heat dissipation efficiency is relatively low. Content of the Utility Model

An interlayer mechanism is fixedly connected to the inner surface of the flywheel housing main body. The interlayer mechanism includes a partition board. A fixed screw sleeve and a strengthening mechanism are fixedly connected to the outer surface of the partition board. A fixing ring is fixedly connected to the through hole inside the partition board. A ventilation hole is opened inside the fixing ring. A heat conduction layer is arranged on the outer surface of the partition board. The strengthening mechanism includes a strengthening sleeve column. A strengthening support rod is slidably connected to the inner surface of the strengthening sleeve column. A hydraulic oil cavity is arranged inside the strengthening sleeve column.
[0005] Preferably, a reinforcing plate is fixedly connected to the outer surface of the flywheel housing main body, and a crankshaft hole is opened inside the flywheel housing main body.
[0006] Preferably, mounting holes are opened inside both the flywheel housing main body and the reinforcing plate, and the inside of the mounting holes is communicated with the inside of the fixed screw sleeve.

[0011] (1) For this transfer case flywheel housing, through the strengthening mechanism, not only can the rigidity of the flywheel housing be increased and the durability of the flywheel housing be extended, but also a part of the vibration can be absorbed and weakened by the hydraulic oil in the strengthening sleeve column, so that the vibration transmitted into the flywheel housing main body is weakened, the damage degree of the flywheel housing main body is reduced, and the service life of the flywheel housing is extended.
[0012] (2) For this transfer case flywheel housing, through the provided heat conduction layer, since the heat conduction layer is made of heat conductive silicone grease material, when heat is transmitted to the flywheel housing, the heat conduction layer can enhance the heat conductivity of the flywheel housing, so that the heat dissipation efficiency of the flywheel housing is improved.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.
[0019] Embodiment 1:
[0020] As Figures 1-4As shown in the figure, the utility model provides a transfer case flywheel housing, which includes a flywheel housing main body 1. An interlayer mechanism 4 is fixedly connected to the inner surface of the flywheel housing main body 1. The interlayer mechanism 4 includes a partition plate 41. A fixed screw sleeve 43 and a strengthening mechanism 44 are fixedly connected to the outer surface of the partition plate 41. A fixed ring 45 is fixedly connected to the through hole inside the partition plate 41. A ventilation hole 46 is provided inside the fixed ring 45. A heat conduction layer 42 is arranged on the outer surface of the partition plate 41. The strengthening mechanism 44 includes a strengthening sleeve column 441. A strengthening strut 442 is slidably connected to the inner surface of the strengthening sleeve column 441. A hydraulic oil cavity 443 is arranged inside the strengthening sleeve column 441.
[0021] Specifically, a reinforcing plate 3 is fixedly connected to the outer surface of the flywheel housing main body 1. A crankshaft hole 2 is provided inside the flywheel housing main body 1.
[0022] Specifically, mounting holes 5 are provided inside both the flywheel housing main body 1 and the reinforcing plate 3. The inside of the mounting holes 5 is communicated with the inside of the fixed screw sleeve 43.
[0023] Specifically, the outer surface of the fixed ring 45 is fixedly connected to the inner surface of the flywheel housing main body 1. The outer surface of the strengthening sleeve column 441 is fixedly connected inside the flywheel housing main body 1. The output end of the strengthening strut 442 is fixedly connected to the outer surface of the partition plate 41.
[0024] Specifically, the heat conduction layer 42 is made of heat-conducting silicone grease material, and the number of the strengthening mechanisms 44 is several.
[0025] The working principle and beneficial effects of the above embodiments.
[0026] During use, a partition plate 41 is added inside the flywheel housing main body 1. The strengthening mechanism 44 is arranged in the space between the flywheel housing main body 1 and the partition plate 41 to increase the rigidity of the flywheel housing and extend the durability of the flywheel housing. When the transfer case operates, the vibration of the engine is transmitted to the flywheel housing main body 1. Since the hydraulic oil cavity 443 is filled with hydraulic oil, and the hydraulic oil is a liquid with a relatively large density, when the strengthening mechanism 44 is subjected to vibration, part of the vibration is absorbed and weakened by the hydraulic oil, so that the vibration transmitted into the flywheel housing main body 1 is weakened, reducing the damage degree of the flywheel housing main body 1. A heat conduction layer 42 is arranged on the outer surface of the partition plate 41. The heat conduction layer 42 is made of heat-conducting silicone grease material. When heat is transmitted to the flywheel housing, the heat conduction layer 42 can enhance the heat conductivity of the flywheel housing, improving the heat dissipation efficiency of the flywheel housing.
