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.
