Problems solved by technology

When the motor runs for a long time, the heat generated by the motor will cause the oil and gas in the box to expand. When the vent hole cannot be opened, the pressure of the oil and gas in the box will rise, and the oil and gas will easily pass through the oil seal...

Abstract

The invention discloses an air bleeder of a differential case of an electro-tricycle, and relates to electro-tricycles. A special bleed screw is arranged at one side of a bearing block; an inner thread and a through hole are formed below the bleed screw base; an inner cavity of a bearing block is communicated with the external atmosphere of the differential case by an air-bleed hole in the bleed screw and the through hole below the bleed screw base; a steel ball in the bearing grinds oil and gas bubbles formed by splashing of lubricating oil when the bearing runs at a high speed, so that the oil is separated from gas; air is discharged out of the differential case from the air-bleed hole; the lubricating oil is left inside the box body. A gear and the bearing are kept in a good lubricating state for a long period of time, the service life of the transmission gear in the differential case is greatly prolonged, and the air bleeder has significant effects on further improvement of the work efficiency and reduction of mechanical noises. In addition, the bleed screw is arranged at one side of the bearing block, so that the bleed screw is not easily damaged.

Description

technical field [0001] The invention relates to an electric tricycle, in particular to an air release device for a differential case of an electric tricycle. Background technique [0002] The differential box used on the electric tricycle, the left and right boxes are made of alloy aluminum die-casting, and a small amount of lubricating oil should be filled in the box, and the amount of refueling is generally 100 to 150 milliliters. When the gear rotates at high speed, the lubricating oil lubricates the gear and bearing through splashing. When the gears and bearings are running at high speed, especially when the temperature is low, the lubricating oil splashes to form oil-air foam, and the oil-air foam is easily discharged when the bleed bolt is deflated. The differential box body used on the electric tricycle at present, its deflation bolt is installed on the oil filling hole of the box body, breaks easily. At present, there are two kinds of bleed bolts used on the differ...
