Abstract

The invention discloses an integrated hub unit which comprises a bearing outer ring which is integrally molded with a flange, wherein the bearing outer ring is sleeved on the external surface of a large inner ring which is coaxially arranged; the bearing outer ring is fixedly provided with an ABS (anti lock brake system) sensor, and an impulse generator is arranged between an outer end part of the large inner ring and the bearing outer ring; and the impulse generator is relative to an induction surface of the ABS sensor. The integrated hub unit provided by the invention is of an integrated design, has a signal function and an ABS function, and is compact in structure; a magnetic gear ring is not assembled, the assembly process is simplified, the integral quality is lightened, the cost is saved; the impulse generator is assembled between an outer end part of the large inner ring and the bearing outer ring, and the impulse generator does not bare outside the integrated hub unit; and the impulse generator is prevented from being polluted, the rust-proof ability is strong, the signal is stable, the maintenance is convenient, and the dust seal effect is good.

Description

A kind of integrated hub

Technical field

The present invention relates to the auto parts and components field, relate in particular to a kind of integrated hub of the ABS of having impulse deviser.

Background technology

ABS (anti-skid brake system) is indispensable as the important protection system of running safety, and traditional ABS (anti-skid brake system) comprises parts such as inductor, gear ring, generally is installed on the hub bearing; The automobile hub bearing significant feature 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, automobile is that relatively independent tapered roller bearing or ball-bearing casing parts are pressed into wheelboss inner hole with special-purpose press with hub-bearing unit, again the ABS gear ring is pressed into hub end and forms; The installation of the installation of bearing, oiling, ABS gear ring and the adjustment of play are all carried out on the brake producing line, are characterized in: need apply pretension, installation process is complicated; Need repack with grease; Make fitting process loaded down with trivial details, cost is high, and maintenance also brings many inconvenience.

In the prior art, also have the deficiency of pair hub-bearing unit to improve, as shown in Figure 1, a kind of two generation hub; This hub structure is processed integrative-structure with wheelboss flange 11 and outside race 12, makes smaller volume, and 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, when bearing is installed, possibly cause gear ring 13 to move axially; The flank of tooth is damaged etc., influences the impulse singla of sensor 14, and; Gear ring 13 exposes outside bearing, and is easy contaminated, makes the detection signal distortion.

Summary of the invention

In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of integrated form hub-bearing unit of the ABS of having impulse deviser, can simplify technology, the convenient installation, prevent that the ABS impulse deviser is contaminated, antirust ability is strong, signal stabilization.

The object of the invention will be achieved through following technical scheme:

A kind of integrated hub, comprise one with the integrated outside race of flange, said outside race is socketed on the outside face of the big inner ring of a coaxial setting, is set with an abs sensor on the said outside race; Be provided with an impulse deviser between the outer end of said big inner ring and the said outside race, the sensitive surface of said impulse deviser and said abs sensor is relative.Said abs sensor and impulse deviser maintain certain clearance.

Preferably, above-mentioned a kind of integrated hub, wherein: said 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 form 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 said outside race and the said big inner ring, be connected rotation through said rolling body between said outside race and the said big inner ring; The medial surface of said outside race is provided with raceway in two row, the lateral surface of said big inner ring be provided with and said in the outer raceway of cooresponding two row of raceway, said in the contact surface of raceway and outer raceway be the arc surface that matches with said rolling body respectively.

Preferably, above-mentioned a kind of integrated hub, wherein: said big inner ring side by side in abutting connection with forming, is respectively equipped with the said 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 said two row rolling bodys.

Outstanding effect of the present invention is: a kind of integrated hub of the present invention is the integrated monolithic design, has semiotic function and ABS function, compact conformation; No longer assemble the magnetic gear ring, reduced assembly technology, alleviated the single-piece quality, practice thrift cost; Impulse deviser is assemblied between the outer end and outside race of big 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, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.

The specific embodiment

Embodiment:

A kind of integrated hub of present embodiment, as shown in Figure 2, comprise one and the integrated outside race 1 of flange, outside race 1 is socketed on the outside face of the big inner ring 2 of coaxial setting, is set with abs sensor 3 on the outside race 1; Be provided with impulse deviser 4 between the outer end of big inner ring 2 and the outside race 1, impulse deviser 4 is relative with the sensitive surface of abs sensor 3.Abs sensor 3 maintains certain clearance with impulse deviser 4.Impulse deviser 4 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 3 produces electromagnetic signal, and with galvanic form output, its frequency is consistent with wheel velocity with size.Be provided with two row rolling bodys 5 between outside race 1 and the big inner ring 2, outside race 1 be connected rotation through rolling body 5 between the inner ring 2 greatly; The medial surface of outside race 1 is provided with raceway 6 in two row; Big inner ring 2 is formed by two little inner rings 21 adjacency arranged side by side; Be respectively equipped with the outer raceway 7 of row on the lateral surface of each little inner ring 21, the contact surface of interior raceway 6 and outer raceway 7 is the arc surface that matches with rolling body 5 respectively.Be provided with retainer 8 between the two row rolling bodys 5.

A kind of integrated hub of present embodiment is the integrated monolithic design, has semiotic function and ABS function, compact conformation; No longer assemble the magnetic gear ring, reduced assembly technology, alleviated the single-piece quality, practice thrift cost; Impulse deviser is assemblied between the outer end and outside race of big 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.
