Abstract
The utility model relates to a wheel hub unit, in particular to a gear ring pressure welding type wheel hub unit used for an automobile. The gear ring pressure welding type wheel hub unit comprises a flange plate with an assembled cavity. An assembled chute is arranged in the top portion of the assembled cavity. An assembled circular arc groove is arranged in the tail portion of the assembled cavity. An inner ring I and an inner ting II are embedded into the flange plate in sequence. Outer rings are sleeved outside the inner ring I and the inner ring II. A running pulley is arranged between the outer ring and the inner ring I. A running pulley is arranged between the outer ring and the inner ring II. The positioning of running pulleys is achieved through a holder. A gear ring is sleeved outside the inner ring II. One end of the gear ring extends above the inner ring I. A sensor is connected with the outer ring in an inserted mode. The end face of the head portion of the sensor and the end face of the outer wall of the gear ring are correspondingly distributed. The gear ring pressure welding type wheel hub unit is compact in structure, assembled precision is improved, and service life is prolonged.
Description
Technical field
The utility model is a kind of hub, and particularly a kind of hub of gear ring compression joint type is used for the wheel hub of automobile.
Background technology
Hub structure relative complex of the prior art, and assembly precision is lower, and result of use is unoutstanding simultaneously.
Chinese patent 200420119173.7 discloses a kind of hub with bearing, comprises flange, it is characterized in that described flange is provided with bearing seat outward, is provided with two single-row conical bearings between flange and the bearing seat; Flange is provided with back-up ring near the axle journal outer radius of small end face, and the back-up ring end face compresses the large end face of bearing one inner ring; Bearing seat internal diameter both sides are provided with seal ring, and its outside internal diameter contacts with the flangeseal step, and inboard internal diameter contacts with the external diameter of back-up ring.This structure relative complex, and result of use is relatively poor, and service life is shorter simultaneously.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact conformation, and setting accuracy is high simultaneously, the hub of the gear ring compression joint type that increases the service life.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of hub of gear ring compression joint type, comprise the flange with assembly cavity, the head of described assembly cavity is provided with the assembling skewed slot, the afterbody of described assembly cavity is provided with the assembling arc groove, embed successively on the described flange inner ring I and inner ring II are arranged, described inner ring I and inner ring II overcoat have the outer ring, between described outer ring and inner ring I, be respectively equipped with roller between outer ring and inner ring II, described roller is located mutually by retainer, described inner ring II overcoat has gear ring, one end of described gear ring extends to the top of inner ring I, is plugged with sensor in the described outer ring, the corresponding distribution of outer wall end face of the end face of described sensor head and gear ring.
As preferably, between described inner ring I and outer ring, seal mutually by seal ring respectively between inner ring II and outer ring, described sensor and outer ring tilt distribution.
As preferably, described flange is provided with 4 well-distributed assembly openings, and described outer ring is provided with 4 assembling ear angles, and described assembling ear is provided with knock hole in the angle.
Therefore, the hub of a kind of gear ring compression joint type that the utility model provides, compact conformation improves assembly precision, promotes service life.
