Abstract

The invention discloses a transmission oil pumping device and a using method. According to the device, a nozzle, a throat pipe and a spray pipe are arranged in two transmission cavities, pressure oiltransmitted by an oil pump is sprayed out through the nozzle, an oil outlet of the nozzle partially form a vacuum, liquid oil in the first transmission cavity is sucked into the second transmission cavity through the throat pipe and the spray pipe, when the transmission is operated and the the nozzle is submerged in the liquid oil in the first transmission cavity, the liquid oil at the bottom shell of the first transmission cavity is sucked into the second transmission cavity through the nozzle, so that the liquid level of the first transmission cavity is always lower than the liquid level ofthe second transmission cavity, the oil adding amount of the transmission can be reduced, the weight and cost of the transmission are reduced, the oil stirring loss can be reduced, the transmission efficiency is improved, and the device can be widely applied to various transmissions. The device has the beneficial effects that the oil adding amount of the transmission can be reduced, the transmission efficiency can be improved, and the device is suitable for the transmission with a pressure oil circuit and a plurality of cavities (or the like).

Description

【Technical field】 [0001] The invention belongs to the technical field of transmissions, and in particular relates to a transmission oil suction device and a use method. 【Background technique】 [0002] With the continuous development of the domestic automobile industry, automobile transmissions have developed from traditional manual transmissions to current automatic transmissions and continuously variable transmissions. The purpose is to continuously improve service life and performance, reduce weight and noise, and optimize maneuverability. For this reason, the hydraulic system is widely used in various transmissions. It provides pressure oil with a certain working pressure for the transmission. It is not only the power source inside the transmission, but also ensures the lubrication and heat dissipation of the transmission parts, as well as the normal operation of the control mechanism and the actuator. Work. Therefore, there needs to be enough fluid oil inside the transm...
