Abstract

The utility model discloses an integrated hub unit, which comprises an outer bearing ring integrally formed with a flange, wherein the outer bearing ring is sheathed to the outer surface of a big inner ring coaxially arranged with the outer bearing ring; the outer bearing ring is fixedly provided with an ABS (anti-skid brake system) sensor; a pulse generator is arranged between the outer end part of the big inner ring and the outer bearing ring; and the pulse generator is opposite to the induction surface of the ABS sensor. The integrated hub unit disclosed by the utility model is in an integrated integral-type design, has a signal function and an ABS function, and has the advantages of compact structure, strong anti-rust capability, stable signal, convenience in maintenance and good dustproof and sealing effects, the assembling technology is reduced due to the fact that a magnetic gear ring does not need to be assembled, the integral weight is lightened, and the cost is saved. The pulse generator is assembled between the outer end part of the big inner ring and the outer bearing ring and is not exposed out of the integrated hub unit, and the pulse generator can be prevented from being polluted.

Description

A kind of integrated hub

Technical field

The utility model relates to the auto parts and components field, relates in particular to a kind of integrated hub with the ABS impulse deviser.

Background technology

The ABS(anti-skid brake system) indispensable as the important protection system of running safety, traditional ABS(anti-skid brake system) comprises and generally be installed on the hub bearing by the parts such as inductor, gear ring; The main effect of automobile hub bearing is load-bearing and for the transmission of wheel hub provides accurate guiding, and it is one of brake system of car vitals; In traditional packaging technology, the automobile hub bearing unit is that relatively independent tapered roller bearing or ball-bearing casing parts are pressed into wheelboss inner hole with Special purpose pressing machine, again the ABS gear ring being pressed into hub end forms, the installation of the installation of bearing, oiling, ABS gear ring and the adjustment of play are all carried out at the brake producing line, are characterized in: need apply pretension, installation process is complicated, need repack with grease, so that fitting process is loaded down with trivial details, cost is high, and maintenance also brings many inconvenience.

In the prior art, also there is the deficiency of pair hub-bearing unit to improve, as shown in Figure 1, a kind of two generation hub, this hub structure is made integrative-structure with wheelboss flange 11 and outside race 12, so that smaller volume is convenient for installation and maintenance, safety, dustproof, sealing effectiveness are improved, but ABS gear ring 13 still need be pressed into flange 11 outer faces, may cause gear ring 13 to move axially when bearing is installed, the flank of tooth is damaged etc., affects the impulse singla of sensor 14, and, gear ring 13 exposes outside bearing, and is easily contaminated, makes the detection signal distortion.

The utility model content

In view of the defective that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of integrated form hub-bearing unit with the ABS impulse deviser, can simplify technique, the convenient installation, prevents that the ABS impulse deviser is contaminated, and antirust ability is strong, signal stabilization.

The purpose of this utility model will be achieved by the following technical programs:

A kind of integrated hub, comprise one with the integrated outside race of flange, described outside race is socketed on the outside face of the large inner ring of a coaxial setting, is fixedly installed an abs sensor on the described outside race; Be provided with an impulse deviser between the outer end of described large inner ring and the described outside race, described impulse deviser is relative with the sensitive surface of described abs sensor.Described abs sensor and impulse deviser maintain certain gap.

Preferably, above-mentioned a kind of integrated hub, wherein: described impulse deviser has magnetic material.In magnetic material inside several magnetic field is arranged, rotate with wheel hub, the magnetic line of force of cutting abs sensor produces electromagnetic signal, and with galvanic formal output, its frequency is consistent with wheel velocity with size.

Preferably, above-mentioned a kind of integrated hub, wherein: be provided with two row rolling bodys between described outside race and the described large inner ring, pass through described rolling body connection of rotating between described outside race and the described large inner ring; The medial surface of described outside race is provided with raceway in two row, and the lateral surface of described large inner ring is provided with the outer raceway of corresponding with described interior raceway two row, and the contact surface of described interior raceway and outer raceway is the arc surface that matches with described rolling body respectively.

Preferably, above-mentioned a kind of integrated hub, wherein: described large inner ring side by side in abutting connection with forming, is respectively equipped with the described outer raceway of row by two little inner rings on the lateral surface of each little inner ring.

Preferably, above-mentioned a kind of integrated hub, wherein: be provided with a retainer between the described two row rolling bodys.

Outstanding effect of the present utility model is: a kind of integrated hub of the present utility model is the integrated monolithic design, has semiotic function and ABS function, compact conformation; No longer assemble the magnetic gear ring, reduced assembly technology, alleviated whole quality, save cost; Impulse deviser is assemblied between the outer end and outside race of large inner ring, does not expose the outside at integrated hub, can prevent that impulse deviser is contaminated, and antirust ability is strong, and signal stabilization is easy to maintenance, and exclusion seal is respond well.

Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
