Embodiment
To be easy to understand technological means, creation characteristic, reached purpose and effect of the invention realized, with reference to
Embodiment, is expanded on further the present invention.
The present invention provides a kind of technical scheme：A kind of electronic water pump for automobile housing, as indicated with 1, the housing include shell
100, the left and right sides of shell 100 is connected to leg 200, and the leg 200 includes base plate 201 and forward and backward wing plate
202nd, 203, the forward and backward wing plate 202,203 is upwardly extended positioned at both sides before and after base plate 201 and in the upper surface of base plate 201, described
Forward and backward wing plate 202,203 is connected close to one end of shell 100 with shell 100, the forward and backward wing plate 202 of correspondence on the base plate 201,
There is mounting hole 300 between 203, in the case of the thickness of base plate 201 is not increased, leg is improved by forward and backward wing plate 202,203
200 intensity, bolt etc. passes through and electronic water pump is arranged in engine nacelle after mounting hole 300；It is provided with the base plate 201
Fabrication hole 211, the lower section of the base plate 201 has a locating ring 220 being coaxially located at outside fabrication hole 211, the locating ring 220 it is interior
Hole is provided with the cylindrical axle sleeve 230 in three-level ladder with the formation shoulder hole of fabrication hole 211, the shoulder hole, and the mounting hole 300 is
The centre bore of axle sleeve 230, two ladder end faces 231,232 of the axle sleeve 230 are born against in base plate 201 and locating ring 220
Lower surface.Axle sleeve 230 is individually processed with base plate 201, and after the fabrication hole 211 on base plate 201 is machined, axle sleeve 230 is pacified
In fabrication hole 211, because locating ring 220 can play circumferentially positioned effect to axle sleeve 230, meanwhile, locating ring 220 it is interior
Hole with diameter greater than fabrication hole, the i.e. endoporus of locating ring 220 and the formation stages hole of fabrication hole 211, the outer wall and ladder of axle sleeve 230
