Description
Technical field
The present invention relates to a kind of electro-tricycle, be specifically related to a kind of air bleeder of differential case of electro-tricycle.
Background technology
The differential case used on electro-tricycle, left and right casing uses alloy aluminum die casting to form, to load in casing
A small amount of lubricating oil, volume read-out is typically at 100 to 150 milliliters.Gear is when high speed rotating, and lubricating oil is right by splashing
Gear and bearing are lubricated.Gear and bearing are when running up, and especially when temperature is relatively low, lubricating oil splash is formed
Oil gas foam, during bleeder screw venting, easily goes out oil gas foam drainage.The differential used on electro-tricycle at present
Device casing, its bleeder screw is arranged on the tank filler sleeve of casing, easily severs.The venting used on differential case at present
Bolt has two kinds, and a kind of is shorter bleeder screw, and its air vent is shorter, and the mist of oil got up that splashes easily is arranged from air vent
Go out.Another kind of bleeder screw is spring controlled long air vent, and the elastic force of spring is difficult to control, and elastic force hour mist of oil is discharged,
When elastic force is big, gas can not arranged.When motor long time running, the heat that motor produces can allow the oil gas in casing expand, when
When air vent can not be opened, the oil-air pressure in casing rises, and oil gas easily propagates through the oil sealing on semiaxis and motor shaft and enters
Stopping pot and motor internal, leakage of oil can cause brake failure after entering pot of stopping, and easily causes security incident, after leakage of oil enters motor,
Motor damage can be caused.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of air bleeder of differential case of electro-tricycle, at left case
Intracoelomic cavity is positioned at the side of bearing block and makes bleeder screw seat, makes female thread and makes through hole, put under bleeder screw seat

The air in portion is through.Bearing is when running up, and lubricating oil splash is formed oil gas foam and pulverizes by the steel ball in bearing, makes
Oil-gas Separation, air is discharged to case of differential external body from air vent, and lubricating oil is stayed in casing.
The present invention is achieved through the following technical solutions: a kind of air bleeder of differential case of electro-tricycle, differential mechanism
Casing is connected and fixed by bolt symmetry by the close left box body of two shapes and right case；Described left and right box
Body is the shape that upper end is little, lower end big, be similar to wooden dipper, and the small end of right case is connected with motor by motor adpting flange.
The big end of left and right casing is installed differential mechanism, differential mechanism and two semiaxis and is connected；It is double that speed change is installed at the middle part of left and right casing
Connection gear, described speed change duplicate gear is arranged on the middle part of left and right casing by bearing and bearing block.Left box body big
Both sides, end have oil filler point and drain oil, oil filler point and drain oil respectively with adding, drain oil bolt is blocked, it is ensured that do not leak
Oil；Bleeder screw is installed on left box body.It is characterized in that: described bleeder screw is arranged on the side of bearing block；Venting
Making air vent on bolt, described air vent is through with the air of case of differential external body by the inner chamber of bearing block.
The side being positioned at bearing block at left box body inner chamber makes bleeder screw seat, and bleeder screw seat outer end makes female thread, institute
The bleeder screw stated is arranged on bleeder screw seat by female thread；Bleeder screw seat the inner makes through hole, described through hole
Through with the inner chamber of bearing block.
The nuts of described bleeder screw installs sealing gasket additional with the joint portion of bleeder screw seat.
The positive effect of the present invention is:
1, venting bolt is arranged on the side of bearing block, and bearing is when running up, and the steel ball in bearing is by lubricating oil splash shape
Olefiant gas foam pulverizes, and makes Oil-gas Separation, and air is discharged to case of differential external body from air vent, and lubricating oil is stayed in casing.
Make gear and bearing keep good lubricating status for a long time, be greatly improved the service life of differential case.To carrying further
Work efficiency and the reduction mechanical noise of high motor have remarkable result.
2, air vent is the most penetrating, body inside and outside air pressure balance, prevents oil gas from passing through oil sealing and enters stop pot and motor.
3, bleeder screw is arranged on the side of bearing block, it is not easy to broken.
4, compact conformation, makes simple, it is simple to promote the use of.
