Shell body, main reducer provided with same and vehicle

Abstract

The invention provides a shell body, a main reducer provided with the same and a vehicle. The shell body comprises an outer shell and a blocking structure; a main cavity, a decompression passage and adecompression hole are formed in the outer shell; the decompression passage and the decompression hole communicate with the main cavity respectively and the decompression passage communicates with the decompression hole; the blocking structure comprises an enclosure bulkhead and at least one oil blocking plate; the enclosure bulkhead is attached to the inside of the outer shell; the enclosure bulkhead and the outer shell jointly limit to form a blocking cavity; the blocking cavity is positioned between an outlet of the decompression passage and the decompression hole; and the oil blocking plate is positioned in the blocking cavity and is attached to the outer shell, so the blocking cavity is divided into at least two blocking subcavities which communicate with each other. The blocking mechanism improves the effect of blocking oil liquid and prevents the oil liquid from passing through and reaching the position of a one-way valve positioned in the decompression hole, so the problems ofoil impregnation and oil leakage at the position of the one-way valve are finally solved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a housing, a final reducer with the same and a vehicle. Background technique [0002] In the main reducer assembly of the front axle of an off-road vehicle, a check valve 30 of the Q900B type is used for pressure relief. Isolation, leaving a smaller pressure relief channel 12 for exhaust, the specific structure is as follows figure 1 shown. However, because the gear of the main reducer has a stirring effect on the gear oil during operation, especially the oil rejection during high-speed operation, the oil retaining effect of the pressure relief structure at this place is weakened. After the oil passes through the pressure relief passage 12, it will Driven by the air flow, the accumulation at the check valve 30 will overflow together with the high-pressure gas when the check valve 30 is opened to release pressure, and then the oil leakage problem will appear, causing complaints from cust...
