Abstract
The utility model relates to an exhaust device for an automotive transmission, which comprises an exhaust plug and a spring seat which are arranged on a gear shifting case cover assembly of the automotive transmission. The edge of a base of the spring seat extends outwards, and an extension part of the spring seat is positioned above the exhaust plug and used for shielding an exhaust hole in the exhaust plug. The exhaust device has the benefit that as the extension part is arranged on the edge of the base of the spring seat in the prior art, positioned above the exhaust plug and used for shielding the exhaust plug, the possibility that agitated lubricating oil is sprayed onto the position of the exhaust plug in the high-speed rotation process of the transmission is avoided, and the possibility that the lubricating oil is sprayed from the exhaust plug to generate oil leakage is effectively prevented.
Description
Technical field
The utility model relates to the technical field of automotive transmission, is specifically related to a kind of venting gas appliance of automotive transmission.
Background technique
Automotive transmission is after the intensification that runs up, and the venting gas appliance of automotive transmission can impel the speed changer inside and outside air pressure balance with being communicated with inside and outside the speed changer.To shown in Figure 5, the venting gas appliance of existing automotive transmission comprises the venting plug 3 that is arranged on the gearshift case lid assembly 4 like Fig. 3.For the lubricant oil that in balance gearbox external and internal pressure, can also avoid speed changer sprays or oozes out from venting plug, this venting plug 3 is arranged on the top of speed changer.But the speed changer that runs up still often stirs the venting plug place with lubricant oil or the mist of oil that produces is sprayed at the venting plug place, and causes the venting plug place that ejection takes place or ooze out lubricated oil condition.The leakage of oil meeting causes the minimizing of lubricant oil for a long time, and finally running and the life-span to speed changer exerts an influence, and the venting gas appliance of therefore existing speed changer must improve, and avoids taking place the situation of oil spout of venting plug place or leakage of oil.
Summary of the invention
The purpose of the utility model provides a kind of venting gas appliance of automotive transmission, can prevent oil spout of venting plug place or leakage of oil.
The venting gas appliance of the described a kind of automotive transmission of the utility model comprises venting plug and the spring seat on the gearshift case lid assembly that is arranged on automotive transmission; The susceptor edges of spring seat stretches out, and the extension is positioned at the top of venting plug and the exhaust port on the venting plug is blocked.
The utility model is through to being provided with the extension on the spring seat susceptor edges of the prior art; And this extension is positioned at the top of venting plug and venting plug is blocked; Thereby avoid the speed changer lubricant oil that stirs in the process that runs up to be sprayed onto the venting plug place; Simultaneously since spring seat be fixedly connected on the case lid of shifting gears with venting plug; Spring seat and venting plug can not produce relative movement, thereby have prevented that effectively lubricant oil from producing the situation of leakage of oil from the venting plug ejection, and the speed changer long-play can be owing to being provided with the minimizing that venting plug causes lubricant oil yet.In addition, the utility model only need improve spring seat of the prior art, and the cheap and result of design cost is easy to realize, is adapted at large scale application on the existing speed changer.
