Abstract

The invention discloses a planet gear set lubricant circuit of a transmission case. The planet gear set lubricant circuit comprises a connecting hole, a sun gear lubricant supply hole and a lubricant guide hole; the connecting hole disposed in a gear inner hub of the transmission case is communicated with a lubricant outgoing hole of the transmission case and allows lubricant to flow to planet gear and gear ring mounting positions; the sun gear lubricant supply hole provided in a sun gear of the transmission case is communicated with a lubricant guide pipe of the transmission case; the lubricant guide hole provided in a planet carrier of the transmission case is communicated with the sun gear lubricant supply hole allows the lubricant to be guided to a planet carrier mounting position. A novel lubricant supply path is added to a planet gear set, the lubricant can more sufficiently flow to the planet gear set without the aid of a lubricant supply hole of a power input shaft, and the planet gear set can be lubricated more sufficiently.

Description

technical field [0001] The invention relates to the technical field of vehicle accessories, more specifically, to a planetary row lubricating oil circuit of a gearbox. Background technique [0002] The gearbox is an indispensable part of the normal driving of the vehicle. When the gearbox is working, it needs lubricating oil to lubricate multiple parts in the gearbox. Therefore, multiple lubricating oil circuits need to be set on the gearbox, such as on the valve plate of the gearbox. The output port 01 of the oil pump connected to the gearbox and the oil supply hole 03 of the hydraulic torque converter control valve 02 are provided, and the lubricating oil is led out from the hydraulic torque converter control valve 02 and sent to the casing of the gearbox The export oil supply hole 04, such as figure 1 and figure 2 Shown (the dotted arrow in the figure is the flow path of lubricating oil). [0003] In the gearbox, the power input shaft and the planetary row are two of ...
