Driving lubrication structure of speed changer

Abstract

A driving lubrication structure of a speed changer comprises an electronic oil pump, a spacer, a first oil pipe, a one-way valve and a second oil pipe. The spacer is connected with the electronic oil pump and the first oil pipe. The one-way valve is connected between the first oil pipe and the second oil pipe. The spacer is internally provided with a first oil duct for conveying lubricating oil to the lower portion of the speed changer, and a second oil duct for conveying lubricating oil to the upper portion of the speed changer, and the lubricating oil entering the spacer passes through the electronic oil pump, then is injected back to the spacer and flows out through a first oil duct outlet of the first oil duct and a second oil duct outlet of the second oil duct. The first oil pipe is connected with the second oil duct outlet, and the second oil pipe leads to the upper portion of the speed changer. According to the driving lubrication structure of the speed changer, the lubricating oil is conveyed to a clutch on the lower portion of the speed changer and a motor module on the upper portion of the speed changer by additionally arranging the spacer and the one-way valve, oil consumption is reduced, and lubricating is really achieved as required.

Description

technical field [0001] The invention relates to the field of automobile transmissions, in particular to an active lubrication structure of the transmission. Background technique [0002] With the increasing shortage of energy and stricter emission regulations, hybrid vehicles have become an option for energy saving and emission reduction. As an important part of this new technology, the hybrid transmission has added a motor drive to the traditional transmission, so the lubrication of the motor module components has also become a key focus in the development of automotive product components. [0003] In the existing hybrid transmission, since the motor module is at the highest end of the transmission, if only the transmission body is splash lubricated, the internal motor gear, idler gear, bearing and other parts of the motor module will be insufficiently lubricated. If oil pipes and other parts are added outside the motor module for lubrication, when the transmission perform...

Problems solved by technology

[0003] In the existing hybrid transmission, since the motor module is at the highest end of the transmission, if only relying on the splash lubrication of the transmission body, the internal motor gear, idler gear, bearing and other parts of the motor module will be insufficiently lubricated

If oil pipes and other parts are added outside the motor module for lubrication, when the transmission performs operations such as shifting gears, the electronic oil pump will respond to the oil demand of the transmission body and provide more oil to the transmission. Too much, and too much oil in the motor module will affect the lubrication and cooling of the transmission body
