Abstract
An integrated sensor-type automobile hub bearing unit belongs to automobile component equipment. The defect that the induction is no longer in force, because an induction surface and a gear ring of a rotational speed sensor are easily covered by foreign matters such as silt exists in a traditional ABS rotational speed induction mechanism. The integrated sensor-type automobile hub bearing unit is characterized in that the rotational speed induction mechanism and the hub bearing unit are integrated, a through hole is formed on an outer ring of the bearing of the hub bearing unit, the rotational speed sensor is mounted in the through hole, the gear ring is sleeved in an inner ring of the bearing, a gear top surface of the gear ring is opposite to the induction surface of the rotational speed sensor, the gear ring of the induction mechanism and the induction surface of the rotational speed sensor are positioned within a sealing part inside the bearing, so that the influence caused by the coverage of foreign matters such as silt is avoided, and the ABS induction mechanism can be normally operated.
Description
Technical field
The utility model belongs to the auto parts and components field, and is especially relevant with a kind of integrated transducer formula automobile hub bearing.
Background technique
ABS (antilock braking system (ABS)) is by constantly detecting the rotating speed of each wheel as the rotating speed induction mechanism of signal source, calculate at that time wheel slip by computer, and compare with desirable slip rate, make the decision that increases or reduce the break retardation pressure, command execution mechanism in time adjusts retardation pressure, is in desirable braking state to keep wheel.The rotating speed induction mechanism of tradition ABS comprises speed probe and gear ring, generally is installed on universal ball cage or the transmission shaft, and gear ring and speed probe sensitive surface are covered by impurity such as silts easily, causes induction to be lost efficacy.
The model utility content
The purpose of this utility model is exactly to overcome the easy defective that lost efficacy of induction that above-mentioned ABS rotating speed induction mechanism exists, and a kind of integrated transducer formula automobile hub bearing that can protect ABS rotating speed induction mechanism and can make the sensitive induction of ABS vehicle wheel rotational speed is provided.For this reason, the utility model is by the following technical solutions:
Integrated transducer formula automobile hub bearing, comprise bearing, cover cap and have the flange plate of Bearing Installation axle, the inner ring fixed cover of bearing is loaded on the Bearing Installation axle of flange plate, the outer ring of cover cap and bearing is fixed, it is characterized in that the outer ring of described bearing is provided with the through hole that connects inside and outside wall, and speed probe is installed on the through hole, fixed cover is equipped with gear ring on the inner ring of described bearing, and the gear ring Topland is relative with the speed probe sensitive surface.
When the utility model used, flange plate and wheel were fixed, and bearing outer ring is installed on the chassis goat's horn and fixes with vehicle body, when automobile was advanced, gear ring was with wheel, the rotating speed of speed probe induction gear ring, thereby sense the rotating speed of wheel, then induced signal is transported to computer.
As to technique scheme replenish and perfect, the utility model also comprises following technical characteristics:
Be provided with seal ring between described through-hole wall and the described speed probe, seal.
Be provided with pad between the outer wall of described speed probe and bearing outer ring, the insertion depth that is used to regulate speed probe changes the distance between sensitive surface and the gear ring Topland, thereby regulates the induction of speed probe.
The center line of described through hole and the axis of bearing are in an acute angle, gear ring Topland and gear ring axis are in an acute angle, make the gear ring Topland relative with the speed probe sensitive surface, can change the spacing of Topland and sensitive surface by the position on the bearing inner race of mobile gear ring, thereby regulate the induction of speed probe.
Use the utility model can reach following beneficial effect: by ABS induction mechanism and hub-bearing unit is integrated, make the gear ring and the speed probe sensitive surface of induction mechanism be positioned at bearing inner sealing environment, avoid the covering influence of impurity such as silt, make ABS induction mechanism proper functioning.
