Abstract

The utility model relates to the technical field of automobiles, and discloses an oil leakage protection structure, which includes a camshaft, the camshaft is connected to a brake bottom plate, and both sides are sealed with oil seals, and a bushing is arranged inside the brake bottom plate. There is an oil passage in the camshaft, one end of the oil passage is connected to the oil nozzle, and the other end is connected to the inner oil passage of the bush. The inner oil passage of the bush is provided with a through hole and connected to the oil drain hole on the bush. The drain hole is provided with a drain nozzle.

Description

A kind of oil leakage protection structure

technical field

The utility model relates to the technical field of automobiles, in particular to an oil leakage protection structure.

Background technique

When adding grease to the contact area between the camshaft and the brake bottom plate, due to the frequent friction between the two parts, it is necessary to add enough grease. However, because the traditional seal adopts the "O" ring seal, and the excess grease cannot be discharged in a timely and reasonable manner, the excessive oil pressure of the grease will inevitably overflow at the "S" end face of the camshaft, and it may fall On the inner wall of the brake drum and the brake lining, the braking performance is greatly reduced, causing a great potential safety hazard.

Contents of the invention

Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide an improvement to the structure, design the "O" ring seal as an oil seal, and increase the drain nozzle at the same time, which can ensure sufficient lubrication of the camshaft , and the excess lubricating grease can be discharged through the oil drain nozzle to prevent excessive oil pressure from overflowing and dripping from the "S" end of the camshaft to the inner wall of the brake drum, which affects the oil drain protection structure of the braking performance.

In order to solve the above technical problems, the technical solution adopted by the utility model is: an oil leakage protection structure, including a camshaft, the camshaft is connected to the brake base plate, and both sides are sealed with oil seals, and the brake base plate is equipped with There is a bushing, the camshaft is provided with an oil passage, one end of the oil passage is connected to the oil nozzle, and the other end is connected to the inner oil passage of the bush, the inner oil passage of the bush is provided with a through hole, and the oil passage on the Unicom bushing An oil drain hole is provided with an oil drain nozzle.

The advantages of the utility model oil drain protection structure are:

1. The oil drain protection structure of the utility model can not only fill a sufficient amount of lubricating grease at the lubricating nozzle to improve lubrication, but also prevent the lubricating grease from entering the brake drum and improve braking performance.

Description of drawings

Fig. 1 is the structural representation of the utility model.

detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, an oil leakage protection structure is characterized in that it includes a camshaft 1, the camshaft 1 is connected to a brake base plate 3, and both sides are sealed with oil seals 2, and the brake base plate 3 is provided with The bushing 8, the camshaft 1 is provided with an oil passage 9, one end of the oil passage 9 is connected to the oil nozzle 10, and the other end is connected to the inner oil passage 6 of the bush, and the inner oil passage 6 of the bush is provided with a through hole 5 , and communicate with the oil drain hole 11 on the bushing 8, and the oil drain hole 11 is provided with a drain nozzle 7.

The user fills grease from the grease nipple 10 during maintenance, the grease enters through the camshaft oil passage 9 and fills the camshaft bushing inner oil passage 6 and the oil storage pit 4, and excess grease can overflow from the drain nozzle 7. Avoid spillage from the S end into the brake drum.

The purpose of the present invention is to design the "O" ring seal as an oil seal by improving the structure, and increase the drain nozzle at the same time, which can not only ensure sufficient lubrication of the camshaft, but also discharge excess grease through the drain nozzle to avoid oil leakage. Excessive pressure overflows from the "S" end of the camshaft and drips to the inner wall of the brake drum, affecting the braking performance. The advantage of this method is that it can not only add enough lubricating grease to the grease nipple to improve lubrication, but also prevent the lubricating grease from entering the brake drum and improve braking performance.

Of course, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above-mentioned examples. Those of ordinary skill in the art can make changes, changes, additions or replacements within the essential scope of the present utility model. Should belong to the protection scope of the utility model.
