Embodiment Construction

[0017] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0018] Such as figure 1 As shown, this embodiment includes: a breather assembly 1, an oil baffle 2, an oil baffle 3 and a bolt 4, wherein the oil baffle 2 is fixedly arranged on the casing of the transmission through the bolt 4 and forms a half with the casing. In the closed cavity, the oil baffle plate 3 is fixedly arranged under the oil baffle plate 2, and the breather assembly 1 is located on the side of the transmission case and communicates with the semi-closed cavity.

[0019] Such as figure 2 As shown, the ventilation assembly 1 includes: a rubber one-way valve 5, an extension tube 6 and a vent plug 7, wh...

Abstract

The invention discloses an oil baffle type ventilation mechanism in the technical field of manual transmissions, comprising a ventilation assembly, an oil baffle, an oil retaining clapboard and a bolt, wherein the oil baffle is fixedly arranged on the shell of a transmission and forms a semi-closed cavity with the shell, the oil retaining clapboard is fixedly arranged below the oil baffle, the ventilation assembly is located on the side face of the shell of the transmission and is communicated with the semi-closed cavity, and the oil baffle is in a semi-open structure and comprises a bottom plate and a baffle arranged vertically above the bottom plate. The invention has the advantages of simple structure, obvious oil retaining effect, good oil-leakage prevention effect, reliable ventilation and the like, and solves the problem that the ventilation plug of the transmission is easy to leak oil due to the traditional ventilation plug is arranged in an oil splashing direction.

Description

technical field [0001] The invention relates to a device in the technical field of manual transmission, in particular to an oil baffle type ventilation mechanism. Background technique [0002] The ventilation system of a traditional transmission is mainly composed of a housing-shaped cavity and a ventilation plug. The traditional mechanism is simple in structure and reliable in operation, and is widely used in various types of automobiles. However, the traditional vent plug is in the direction of oil splash and cannot solve the problem of transmission oil leakage. This type of system mainly includes the two functions of transmission ventilation and isolation of transmission fluid. The mechanism has the advantages of simple structure, good oil leakage prevention effect, reliable ventilation and the like. [0003] After searching the existing technology, it was found that the Chinese patent document number CN201162816Y, the announcement date was 2008-12-10, recorded a transm...
