Crimping, crimping are close to one end of inner ring；First raceway groove is built with 18 balls, and the second raceway groove is built with 20 balls；Outside inner ring
Speed sensor is additionally provided with, speed sensor includes magnetic induction head and alloy tooth annulus.Chinese patent also discloses a kind of vapour
Wheel hub bearing unit（Authorization Notice No.：CN201401445）, it includes ring flange inner ring, flange plate outer ring, inside race, rolling
Pearl and retainer, flange plate outer ring inner surface are provided with two outer raceways, are respectively provided with ring flange inner ring and inside race outer surface
The interior raceway corresponding with outer raceway, ball are placed in retainer inscribe between interior raceway and outer raceway, ring flange inner ring
There is annular groove and step surface on outer surface, annular retaining ring is provided with groove, inside race end face is resisted against on annular retaining ring,
Other end is resisted against on step surface.But this hub sealing property in install sensor is poor, dust easily from
Outside intrusion, so as to cause transmission relatively to have some setbacks, operating efficiency is relatively low.
Utility model content
The utility model is to provide a kind of automobile hub unit with high leakproofness linear transducer, and it mainly solves existing
Have that the sealing property in install sensor of the hub present in technology is poor, dust easily invades from outside, so as to cause
Transmission relatively has some setbacks, the more low technical problem of operating efficiency.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
Automobile hub unit of the present utility model with high leakproofness linear transducer, including ring flange, described flange
Bolt is connected with disk, ring flange end is provided with crimping, and ring flange is provided with long inner ring, short inner ring, long inner ring, short inner ring peripheral hardware
There is outer ring, roller is provided between outer ring and long inner ring, short inner ring, roller is provided with retainer, and long inner ring is provided with gear ring, outer ring
On be provided with oblique through hole, worn in oblique through hole and be connected to linear transducer, O-ring is provided between linear transducer and through hole.Online
Property sensor at install additional O-ring, can so prevent dust from being invaded from outside inside hub.
Preferably, it is designed with seal assembly, seal assembly between the interior outer end of described outer ring and long inner ring, short inner ring
Include the metallic framework that a pair of sections are L-type, metallic framework is provided with seal, and seal is provided with spring.Pass through spring
So that seal is more flexible, so enable to sealing effectiveness preferable.
Preferably, the inner of described long inner ring is provided with step surface, step surface is less than the inner surface of long inner ring.This line-transect
Property sensor will not touch long inner ring when mounted, and will not be influenceed after leaving gap by other impurity.
Preferably, the outer surface of described O-ring is provided with some shrinkage pools, the inner width of shrinkage pool is more than its opening.
By shrinkage pool can O-ring there is preferably elasticity, and there is ductility, preferably can live gap seals.
Therefore, the utility model sealing property in install sensor is preferable, and dust is not easy to invade from outside, and transmission is more
Smooth, operating efficiency is higher, simple and reasonable for structure.
