Abstract
The invention discloses an external lubrication device for a transmission and a method. An external lubrication system is added on the basis of an existing transmission lubrication system. The external lubrication device comprises an external lubrication pump and an angle switch. The external lubrication pump is used as a power source of the external lubrication system. The angle switch is used as a control element. When a vehicle reaches the set slope value in the operation process, the external lubrication pump starts by itself, and normally-engaged gears, the third-gear gear and the fourth-gear gear of the transmission are spattered and lubricated through spray nozzles. When the gradient is smaller than the set value, the angle switch is turned off, and the transmission is lubricated through an internal lubrication system of the transmission. The external lubrication device is simple in structure, convenient to operate, high in reliability, capable of effectively solving the lubrication problem under the condition that a wide-body mining vehicle climbs a slope in a heavy-loaded manner, and capable of prolonging the service life of the transmission.
