[0001] The utility model relates to the technical field of gear boxes, in particular to an automobile heat dissipation gear box. Background Art

[0002] An automotive gearbox is a meshing assembly of gears that adjusts, transmits, and distributes engine power to meet the demands of varying driving conditions. After a certain mileage, the gearbox's lubricant needs to be replaced to ensure proper lubrication and prevent wear and corrosion. Continuous operation of the gears in the gearbox with lubricant generates high temperatures, impacting their service life. To address this, we propose a heat-dissipating automotive gearbox. Utility Model Content

[0005] Preferably, a screw groove penetrating the heat dissipation outer box is provided on the top of the closing plate, and the internal thread of the screw groove is connected to a fixing bolt for fixing the closing plate.

[0006] Preferably, when the closing plate is installed in the interior of the installation groove, the periphery of the closing plate is in a butt-sealed state with the interior of the installation groove via a sealing gasket.

[0007] Preferably, a sound insulation pad is provided on the inner side of the heat dissipation outer box, the sound insulation pad is consistent with the internal structure of the heat dissipation outer box and the sound insulation pad itself has sound insulation properties.

[0008] Preferably, a built-in groove is opened inside the gear box, and the built-in groove is a rectangular hollow structure. A connecting frame is installed inside the built-in groove, and the connecting frame is a rectangular hollow structure. A sound-absorbing membrane for blocking and silencing sound waves is provided on the inner side of the connecting frame.

[0009] Beneficial effects

[0010] The utility model provides an automobile heat dissipation gearbox, which has the following beneficial effects:

[0011] 1. The automotive cooling gearbox. The automotive gearbox realizes the adjustment, transmission, and distribution of the engine power through the meshing and combination of gears to meet the needs of the vehicle under different driving conditions. When the vehicle has traveled a certain number of kilometers, it is necessary to replace the lubricating medium in the gearbox to ensure the self-lubricating performance of the gears, prevent wear and corrosion. When the gears inside the gearbox are continuously operating in cooperation with the lubricant, high temperature will be generated inside the gearbox, which will affect the service life of the gears. In this article, a set of cooling outer boxes is sleeved outside the gearbox, and the inside of the cooling outer box contains coolant. The coolant can wrap and soak the outside of the gearbox. At this time, the closing plate can be docked and sealed with the inside of the installation groove. The periphery of the closing plate can be hermetically squeezed with the inner side of the installation groove through the gasket, and then the closing plate can be fixed by screwing the fixing bolt into the internal thread of the screw groove. In this way, when the gearbox is soaked in the coolant for a long time, its own high temperature can be fully reduced, thereby improving the heat dissipation effect of the gearbox itself and extending the service life of the gears inside the gearbox.

[0012] 2. The automotive cooling gearbox. The inner wall of the cooling outer box is coated with a sound insulation pad, and the sound insulation pad itself has sound insulation characteristics. When the gearbox is started and used, the noise inside the gearbox can be initially sound-insulated by the coolant inside the cooling outer box, and the sound insulation pad on the inner side of the cooling outer box can perform secondary sound insulation on the sound wave. The sound absorption film inside the built-in groove can deform and expand during the transmission of the sound wave for a third treatment, so as to improve the noise reduction effect of the gearbox.
