Description

Technical Field

[0001] The utility model relates to the technical field of gearboxes, in particular to an improved automobile gearbox. Background Art

[0002] An automobile gearbox is the meshing and combination of gears to achieve the adjustment, transmission, and distribution of the engine power to meet the needs of the automobile 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 lubrication performance of the gears themselves and prevent wear and corrosion. When the existing lubricating agent is added to the inside of the gearbox for use, the agent will deposit at the bottom of the box body. When the gears rotate and are used, foreign substances will be mixed with the agent. When the agent flows along with the gears, the gears are easily damaged by the foreign substances, affecting the service life. For this reason, we propose an improved automobile gearbox.

A circulating pump is arranged at the top of the machine case. A filter box is installed on one side of the machine case. The filter box is a rectangular hollow box body. An absorption pipe penetrating the filter box is connected to one side of the circulating pump. One end of the absorption pipe is in communication and cooperation with the bottom of the machine case. The other side of the circulating pump is connected to a delivery pipe penetrating the top of the machine case. An installation groove communicating with the inside of the filter box is formed on one side of the filter box. A packaging member is arranged inside the installation groove. A filter screen plate is installed on one side of the packaging member. A filter screen is arranged inside the filter screen plate.

[0005] Preferably, when the circulating pump starts to absorb the deposited oil liquid below the inside of the machine case through the absorption pipe, after the lubricating agent enters the inside of the filter box through the absorption pipe, the agent is in a filtered and recycled state through the filter screen inside the filter screen plate.

[0006] Preferably, after the circulating pump recovers and inhales the lubricating agent through the absorption pipe, the lubricating agent is in a state of re-filling the inside of the machine case through the delivery pipe.

[0007] Preferably, a pressure pad is arranged on the inner side of the installation groove. The pressure pad has a deformation characteristic. The packaging member is in butt joint and assembly cooperation with the inside of the installation groove through the pressure pad. A screw hole penetrating the filter box is formed on one side of the packaging member. A fixing bolt is threadedly connected inside the screw hole.

[0009] Beneficial effects

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

[0011] 1. An improved automobile gearbox. In this article, when lubricating oil is added to the inside of the chassis to cooperate with the operation of the gears, the lubricating oil will be deposited at the bottom of the chassis. When the circulating pump is started, the circulating pump can extract the oil at the bottom of the chassis through the absorption pipe. When the oil passes through the inside of the filter box, it will be filtered through the filter screen inside the filter plate. The filtered oil will be sucked into the circulating pump and discharged through the delivery pipe. The filtered oil is discharged into the chassis through the delivery pipe for continued lubrication. While improving the cleanliness of the lubricating oil, its lubricating effect can be guaranteed, thereby avoiding damage to the gears inside the chassis and increasing the service life of the gears.

[0012] 2. An improved automobile gearbox, wherein the filter screen inside the filter screen plate can filter the oil absorbed by the absorption tube, and a guide cover is installed at the lower part of the filter box. The inner diameter of the guide cover is narrow at the top and wide at the bottom. After the oil enters the filter box through the guide cover, it will be blocked and intercepted by the guide cover. At this time, when the fixing bolts are removed, the filter screen on one side of the package can be removed in conjunction for cleaning and replacement, and foreign matter intercepted inside the filter box can also be cleaned, thereby achieving the effect of ensuring that the filter screen can continuously filter the oil.
