Problems solved by technology

However, the device exposes too much of the transmission housing, which is not conducive to the space layout of the vehicle; at the same time, this part is an independent functional part, which also increases the complexity of the process and the manufacturing cost

Embodiment

[0021] Such as figure 1 and image 3 As shown, the integrated ventilation mechanism 0 is located at the top of the manual transmission housing 1, and includes: a shift rocker 3 sequentially arranged on the selector shift shaft 2, a selector shift cover 4, and a cover 4 socketed on the selector shift shaft 2 The outside selects the shift sleeve 5, and the outside of the shift rocker arm 3 links to each other with one end of the select shift shaft.

[0022] The said shift rocker arm 3 is elastically connected with the shift select shaft 2 , specifically, the elastic pin 11 arranged on the shift select rock arm 3 penetrates through the shift select shaft 2 .

[0023] The shift select cover 4 is a bell-shaped cavity with a hat-like structure and the bottom of the cavity communicates with the inside of the transmission. An oil seal 7 is arranged in the counterbore at the upper end of the select shift cover 4 .

[0024] The oil seal 7 is a radial oil seal with a dust-proof nozzle,...

Abstract

The invention belongs to the technical field of automotive speed changers and discloses an integrated ventilation mechanism of a manual speed changer. The integrated ventilation mechanism is positioned on the top of the shell of the manual speed changer and comprises a shifting rocker arm, a selective shifting cover and a selective shifting sleeve, wherein the shifting rocker arm and the selective shifting cover are sequentially arranged on a selective shifting shaft; the selective shifting sleeve is sleeved outside the selective shifting shaft; and the shifting rocker arm is connected with one end of the selective shifting shaft. The ventilation mechanism is integrated with a selective shifting mechanism of a speed changer, so that lubricating oil steam which is generated when the speed changer works at high speed cannot be spattered to the outer side of a control mechanism, pressure in the speed changer can be effectively balanced, an oil blockage phenomenon can be avoided, the using amount of parts can be reduced, and the mechanism is simplified.

Description

technical field [0001] The invention relates to a device in the technical field of automobile transmission, in particular to an integrated manual transmission ventilation mechanism with the function of preventing oil splash. Background technique [0002] When the transmission is actually working, the gear in the box is under heavy load and high-speed rotation, and the temperature in the box rises rapidly, causing the lubricating oil in the box to generate steam, which fills the space in the box and causes the pressure in the box to rise. If the generated heat and The oil vapor cannot be discharged in time, causing each sealing interface to bear the impact of this pressure, and oil and gas often rush out at the weakest point to cause leakage. Once a leak occurs, a channel is formed, making the leak more and more serious. After the lubricating oil leaks, it will cause a shortage of gear lubricating oil, cause early abrasion damage to gears and bearings, shorten the service li...
