The invention relates to an automobile transmission with an oil control mechanism. It includes transmission mechanism, transmission box body and transmission oil pan; oil quantity control mechanism is set inside transmission oil pan; this mechanism includes oil storage room, oil pump, flow meter and small motor; oil storage room is a horizontal long strip box with closed top, and oil pipe is inserted at the bottom of the box, and the oil storage room is connected with the oil pump through the oil pipe. When the transmission is running, the oil storage room is used to store the lubricating oil in the oil pan of the transmission; when the lubricating oil temperature is low, the oil pump works and sucks the lubricating oil in the oil pan of the transmission into the oil storage room, which gradually reduces the lubricating oil in the oil pan of the transmission; when the lubricating oil temperature is high, the oil pump works and sucks the lubricating oil in the oil storage room back into the oil pan of the transmission. The lubricating oil in the oil pan of the transmission is gradually increased to ensure the sufficient lubrication and heat dissipation of the gears of the transmission, and the oil quantity in the oil pan of the transmission is adjusted.

技术介绍
变速器是汽车动力传动系统中的一个重要组成部分,变速器齿轮的润滑与散热等都离不开变速器润滑油。传统的变速器润滑油的添加方式都是手动添加,一旦润滑油加入量确定后,就不再更改变速器中的润滑油量。润滑油的粘度会受到温度的影响。因此当室外温度较低时,例如冬天或者东北等寒冷地区,会使得润滑油粘度变大。而变速器齿轮是通过飞溅润滑,即齿轮的轮齿部分浸泡在变速器油底壳的润滑油中,齿轮旋转搅动油液,油液飞溅,从而起到润滑的作用。因而当油液粘度变大时,必然会使得齿轮搅动油液的阻力变大,并且润滑油粘度的增加也会使得齿轮啮合面间形成的油膜过厚,齿轮转动时的阻力增加,进一步增加了变速器传递动力时的功率损耗,从而降低变速器的工作效率。因此当温度变低时,应当减少变速器中的润滑油。而当温度变高时,润滑油粘度降低,润滑油变稀,则在啮合齿面之间不能保持足够的油膜,油膜容易被破坏,导致相互啮合的齿轮两金属面直接接 ...
