Abstract
The utility model discloses a deflation device of a differential mechanism box of an electric tricycle, and relates to electric tricycles. A special deflation bolt is installed on one side of a bearing block, a deflation bolt base is arranged on the side, located on the bearing block, of an inner cavity of a left box body, internal threads and a through hole are formed in the lower portion of the deflation bolt base, and an inner cavity of the bearing block and the atmosphere outside the differential mechanism box are communicated through a deflation hole in the deflation bolt and the through hole in the lower portion of the deflation bolt base. When a bearing operates at high speed, lubricating oil is splashed through a steel ball in the bearing to form oil and air foam to be pulverized, oil and air are made to be separated, air is exhausted out of the differential mechanism box through the deflation hole, and the lubricating oil is reserved in the box. A gear and the bearing are kept in a good lubricating state for a long time, the service life of the transmission gear in the differential mechanism box is greatly prolonged, work efficiency of an electromotor is further remarkably improved, and mechanical noise is remarkably reduced. In addition, the deflation bolt is not prone to impact and damage due to the fact that the deflation bolt is installed on one side of the bearing block.

Technical field
The utility model relates to a kind of electro-tricycle, is specifically related to a kind of electric-tricycle differential casing means of deflation.
Background technique
The differential mechanism casing using on electro-tricycle, left and right casing adopts alloy aluminum die casting to form, and in casing, will pack a small amount of lubricant oil into, and volume read-out is generally at 100 to 150 milliliters.Gear is in the time of High Rotation Speed, and lubricant oil is lubricated gear and bearing by splashing.Gear and bearing are in the time running up, and especially, in the time that temperature is lower, lubricating oil splash forms oil gas foam, when bleeder screw venting, easily oil gas foam drainage are gone out.The differential mechanism casing using on electro-tricycle at present, its bleeder screw is arranged on the tank filler sleeve of casing, easily severs.The bleeder screw using on differential mechanism casing at present has two kinds, and a kind of is shorter bleeder screw, and its vent hole is shorter, and the mist of oil splashing is easily discharged from vent hole.Another kind of bleeder screw is spring controlled long vent hole, and the elastic force of spring is restive, and elastic force hour mist of oil is discharged, and when elastic force is large, gas can not arranged.When motor long time running, the heat that motor produces can allow the oil gas in casing expand, in the time that vent hole can not be opened, oil-air pressure in casing rises, oil gas easily enters through the oil sealing on semiaxis and motor shaft stop pot and motor internal, and leakage of oil can cause brake failure after entering the pot of stopping, and easily causes security incident, leakage of oil enters after motor, can cause motor to damage.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of electric-tricycle differential casing means of deflation, a side that is positioned at bearing support at left box body inner chamber is made bleeder screw seat, under bleeder screw seat, make internal thread and make through hole, bleeder screw is arranged on bleeder screw seat by internal thread.Under bleeder screw seat, make through hole, the inner chamber of through hole and bearing support connects.The lower through hole of vent hole on bleeder screw and bleeder screw seat connects the atmosphere of the inner chamber of bearing support and case of differential external body.Bearing is in the time running up, and the steel ball in bearing forms oil gas foam by lubricating oil splash and pulverizes, and makes Oil-gas Separation, and air is discharged to case of differential external body from vent hole, and lubricant oil is stayed in casing.
The utility model is achieved by the following technical solution: a kind of electric-tricycle differential casing means of deflation, and differential mechanism casing is connected and fixed by bolt symmetry by two close left box body and right cases of shape; The shape that described left and right casing is that upper end is little, lower end is large, be similar to wooden dipper, the small end of right case is connected with motor by motor adpting flange.The large end of left and right casing is installed differential mechanism, and differential mechanism is connected with two semiaxis; Speed change duplicate gear is installed at the middle part of left and right casing, and described speed change duplicate gear is arranged on the middle part of left and right casing by bearing and bearing support.The both sides, large end of left box body have oil hole and drain oil, oil hole and drain oil respectively with adding, drain oil bolt blocks, and guarantees oil-proof; Bleeder screw is installed on left box body.It is characterized in that: described bleeder screw is arranged on a side of bearing support; On bleeder screw, make vent hole, described vent hole connects the atmosphere of the inner chamber of bearing support and case of differential external body.
A side that is positioned at bearing support at left box body inner chamber is made bleeder screw seat, and bleeder screw seat outer end makes internal thread, and described bleeder screw is arranged on bleeder screw seat by internal thread; The inner through hole of making of bleeder screw seat, described through hole and the inner chamber of bearing support connect.
The connecting part of the nuts of described bleeder screw and bleeder screw seat installs sealing gasket additional.
Good effect of the present utility model is:
1, venting bolt is arranged on a side of bearing support, and bearing is in the time running up, and the steel ball in bearing forms oil gas foam by lubricating oil splash and pulverizes, and makes Oil-gas Separation, and air is discharged to case of differential external body from vent hole, and lubricant oil is stayed in casing.Make the good lubricating status of the long-term maintenance of gear and bearing, the working life of greatly improving differential mechanism casing.Working efficiency to further raising motor and reduction mechanical noise have remarkable result.
2, vent hole is penetrating all the time, and body inside and outside air pressure balance prevents that oil gas from entering by oil sealing stop pot and motor.
3, bleeder screw is arranged on a side of bearing support, is not easy to be broken.
4, compact structure, makes simply, is convenient to promote the use of.
