Description

Technical Field

[0001] The utility model relates to the technical field of gearbox covers, in particular to a new type of automotive gearbox cover. Background Art

[0002] The gearbox is an important component in the automotive transmission system, mainly including a gearbox, a differential gearbox, a reduction gearbox, etc. The reduction gearbox is also called a planetary reduction gearbox, which can reduce the transmission speed ratio and proportionally increase the engine torque at the same time. It is mainly composed of planetary gears, a sun gear, a ring gear, a planetary carrier, etc. However, when installing the existing automotive gearbox cover, it needs to be fixed one by one through a bolt mechanism. After the lubricant in the gearbox is consumed, it is necessary to frequently disassemble and assemble the bolt mechanism on the cover, resulting in easy wear of the slot holes inside the cover during long-term use, affecting the installation stability of the cover. For this reason, we propose a new type of automotive gearbox cover. Summary of the Utility Model

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a new type of automotive gearbox cover.

[0004] To achieve the above object, the utility model adopts the following technical scheme. A new type of automotive gearbox cover includes a gearbox and a cover. A connection end is integrally formed on the periphery of the gearbox, and a docking end is integrally formed on the periphery of the cover. Screw grooves are formed inside the connection end and the docking end, and fixing bolts are threadedly connected inside the screw grooves. A communication end is integrally formed on the top of the cover. A separation mechanism is installed inside the communication end. A pressure pump is installed at the bottom position of the separation mechanism inside the communication end. An inlet pipe passing through the separation mechanism is installed above the pressure pump. An insertion pipe is arranged at the bottom of the pressure pump, and a drain pipe passing through the insertion pipe is installed at the bottom of the pressure pump. Multiple groups of spray nozzles are arranged on the periphery of the insertion pipe.

[0005] Preferably, after the pressure pump sucks the oil agent above the separation mechanism through the inlet pipe, the pressure pump conveys the oil agent into the insertion pipe through the drain pipe, and the oil agent inside the insertion pipe is sprayed into the gearbox through the spray nozzles.

[0006] Preferably, an assembly thread is formed on the periphery of the communication end, and a threaded cap is arranged on the top of the communication end. The inner side of the threaded cap is threadedly sleeved and connected with the periphery of the communication end through the assembly thread.

[0007] Preferably, an embedding groove is formed inside one side of the edge of the gearbox and the cover. The embedding groove is a three-quarter circular hollow groove body. A wrapping sheet that forms a circular space inside the embedding groove is installed on the inner sides of the gearbox and the cover. The wrapping sheet is an arc-shaped structure. An internal suction pipe is arranged between the embedding groove and the wrapping sheet, and a sealing cover is sleeved and installed at the end of the internal suction pipe.

[0008] Preferably, the internal suction pipe is located in the embedding groove and cooperates with two wrapping sheets to form a wrapped storage state.

[0009] Beneficial effects

[0010] The utility model provides a new type of automobile gearbox cover, which has the following beneficial effects:

[0011] 1. For this new type of automobile gearbox cover, in this article, after the gears inside the gearbox are filled with a lubricant, the cover can be docked and installed with the gearbox. The fixing bolts are thread-fixed in the screw grooves inside the connection end and the docking end. At this time, the lubricant can be filled into the communication end. The lubricant can enter the pressure pump through the liquid inlet pipe. After the pressure pump is started, the agent can be transported under high pressure through the liquid discharge pipe into the insertion pipe. The lubricant can be automatically and evenly sprayed inside the gearbox through the spray heads around the insertion pipe to contact the gears, without the need to frequently disassemble and assemble the gearbox and the cover, so as to achieve the effect of conveniently automatically refueling the inside of the gearbox, reducing the disassembly and assembly frequency of the cover and the gearbox, and improving the installation stability between the cover and the gearbox.

[0012] 2. For this new type of automobile gearbox cover, an embedding groove is formed inside the gearbox and the cover, and two wrapping sheets that form a wrapped storage inside the embedding groove are installed on the inner sides of the gearbox and the cover. A group of internal suction pipes are inserted between the embedding groove and the two wrapping sheets. The internal suction pipes are stored and wrapped between the embedding groove and the wrapping sheets. When replacing the oil agent inside the gearbox, the end of the internal suction pipe can be connected to the pipeline of an external suction device. When the external suction device sucks air, the oil agent inside the gearbox can be sucked out and discharged by the internal suction pipe, so as to achieve the effect of conveniently draining and replacing the oil agent inside the gearbox.
