Abstract
The utility model relates to a vehicle part, in particular to a hub bearing unit with a passive sensor, which is used for solving the problems of complex assembly and poorer safety. The hub bearing unit comprises an external flange (1) and an inner flange (3), wherein a half inner ring (2) is fastened and matched on the inner flange (3). The hub bearing unit is mainly characterized in that a gear ring (9) and a hub nut (7) are arranged on the inner flange (3), the passive sensor (10) is arranged on the outer side of the outer flange (1), and the gear ring (9) and the sensor (10) form a vehicle anti-lock braking system. The hub bearing unit has the advantages of simple and firm structure, better safety performance, and capability of prolonging service life of a vehicle.
Description
Technical field
the utility model relates to a kind of vehicular spare parts, particularly a kind of hub-bearing unit of firm band passsive sensor simple in structure.
Background technology
are present; Common hub-bearing unit is used for automobile only as the effect of transmission and supporting body; Can not play the effect of preventing the brake holding system with automobile, therefore the appearance of the hub-bearing unit of a lot of belt sensor structures arranged also, but generally all be installed on universal joint ball cage or the transmission shaft; Sensor receives the influence of acquired impurities such as silt easily, can produce failure phenomenon.And because the wheel hub structure more complicated, dustproof poor with lubricating function, the whole structure that assembles up is not fine, cost efficiency is all undesirable.
The utility model content
The purpose of
the utility model provides a kind of hub-bearing unit that firmly can cooperate the band passsive sensor of automobile brake system again well simple in structure.
The technical solution of
the utility model is: a kind of hub-bearing unit with passsive sensor; Comprise the outward flange dish; Said outward flange dish is combined with inner flange, fastening half inner ring that is combined with on the said inner flange, and outward flange dish inboard is provided with two raceways; Be respectively arranged with the single raceway that cooperates with said pair of raceway on inner flange and half inner ring; Be provided with rolling body in the raceway, it is characterized in that: hub nut and gear ring are installed on the side of inner flange, and the arranged outside of outward flange dish has sensor.
are preferred as the utility model, and said gear ring is the ABS gear ring.
are preferred as the utility model, and said sensor is a passsive sensor.
antiblock device promptly is made up of ABS gear ring and passsive sensor; Adopt electromagnetic induction principle; Produce the sine wave signal of series according to the moving velocity of automobile; Be passed to the ECU (ECU) of ABS system, ECU converts the sensor sine wave signal square-wave signal of same frequency into through special signal processing circuit, the speed that frequency through detecting square-wave signal or cycle are calculated wheel; And then take corresponding braking effect, anti-skidding, anti-lock effect when playing brake.
are preferred as the utility model, and the outward flange dish is provided with seal ring away from the cooperation position of sensor one side and inner flange.
are preferred as the utility model, and seal ring is made up of the rubber of steel plate frame and corrosion-and high-temp-resistant.This is provided with the leakproofness that can guarantee inner structure, it is isolated from the outside avoids the corrosion contamination of foreign object, and internal lubrication fat is flowed out, and keeps lubricating condition preferably.
are preferred as the utility model, and inner flange is provided with a step with the position that cooperates of half inner ring.Half inner ring is through the support and the inner flange rigid fit of step and hub nut.Because of having fixed half inner ring, play becomes simply, angle of contact is easy to control so match when joining play.
are preferred as the utility model, are provided with retainer in two raceways of outward flange dish inboard, and said retainer locks said rolling body.Guarantee bearing load equably.
are preferred as the utility model, and said rolling body is a steel ball.Strong with steel ball as the rolling body load-carrying capacity, also save cost.
are preferred as the utility model, are combined with boss bolt on the inner flange.Be used for connecting wheel.
the utility model beneficial effect is: it is firmly simple to make that the hub-bearing unit structure becomes; Match the play value easily; Add the anti-preferably brake holding system of compact conformation performance again; Improved the safety of driving greatly, but also provided cost savings the service life of having improved tire.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model embodiment 1.
Among
figure, 1, outward flange dish 2, half inner ring 3, inner flange 4, rolling body 5, retainer 6, seal ring 7, hub nut 8, boss bolt 9, gear ring 10, sensor.
The specific embodiment
are done further explain with embodiment to the utility model below in conjunction with accompanying drawing.
following specific embodiment only is the explanation to the utility model, is not the restriction to the utility model.
said structure is simply firm, and the antiblock device that constitutes through ABS gear ring and passsive sensor has improved the safety performance of automobile, has improved the automobile total quality simultaneously, has prolonged the life-span of automobile.
