Automobile reducer comprising efficient lubricating system and working method of reducer

Abstract

The invention discloses an automobile reducer comprising an efficient lubricating system. The reducer comprises a reducer left end cover, an oil filling port, an inner gear ring, a planetary gear carrier, planetary gears, a sun gear, a planetary gear shaft, a first bearing, a second bearing, an oil distribution disk assembly, a needle bearing, an oil pump assembly, a flange, a flange cover and a reducer right end cover; the lubricating system comprises first oil holes, second oil holes, a first oil pipe, second oil pipes, the oil pump assembly and the oil distribution disk assembly; the firstoil pipe is connected with the oil pump assembly and is arranged on the reducer right end cover; the first oil holes and the second oil holes are formed in the planetary gear carrier; the right ends of the second oil pipes are connected with the first oil holes; and spray oil outlets are formed in the outer walls of the left ends of the second oil pipes and are arranged in the positions where theplanetary gears mesh with the sun gear. By the aid of the efficient lubricating system of the reducer, temperature rise of the reducer due to the high torque is avoided, and key parts of the reducer can be cooled and lubricated by the aid of the arranged oil pipes and the oil holes.

Description

technical field [0001] The invention belongs to the technical field of reducers, in particular to an automobile reducer with a high-efficiency lubricating system. The invention also relates to a working method of an automobile reducer with a high-efficiency lubrication system. Background technique [0002] With the promotion of new energy vehicles, the number of pure electric vehicles is increasing. Unlike small electric vehicles, small and medium-sized electric commercial vehicles on the market have extremely high torque requirements at low speeds. For example, according to the design of small electric vehicles, low speed and high torque The quality and volume of the motor are large, the cost is high, and the transmission reliability is poor. Therefore, in view of this situation, this product innovatively uses a planetary reduction gear with a fixed speed ratio while ensuring the volume and quality of the motor used in electric commercial vehicles. The device is used to en...
