Abstract

The utility model provides an automobile hub unit ABS magnetic ring assembly, which relates to the technical field of hub bearings and solves the technical problem that a rubber magnetic ring of an original automobile hub unit ABS magnetic ring assembly is separated from a hub in daily use so as to influence the locking function of a brake wheel when an automobile is braked in emergency.

Description

Automobile hub unit ABS magnetic ring assembly

Technical Field

The utility model belongs to the technical field of hub bearings, and particularly relates to an ABS magnetic ring assembly of an automobile hub unit.

Background

At present, an ABS system is equipped on an automobile and becomes one of standards of whether the automobile can enter the market, the ABS system is composed of an ABS magnetic ring assembly, a wheel speed sensor, a modulator, a pneumatic device and a brake pad, when the automobile normally runs, the ABS magnetic ring assembly arranged on a hub rotates along with the hub, a rubber magnetic ring is arranged in the ABS magnetic ring, the rotation of the rubber magnetic ring by N poles and S poles which are annularly and equidistantly arranged enables the wheel speed sensor to generate induced electromotive force, the speed of the automobile is calculated through a calculation unit in the modulator, when the wheel speed is calculated by the calculation unit to be lower than a certain threshold value, the modulator enables the brake pad to not brake any more through closing the pneumatic device, and when the speed of the automobile is detected to be higher than a certain threshold value, the brake pad is braked again through the pneumatic device, namely, the open and close states of the brake pad are used for ensuring that the wheel and the ground are always in a sliding friction state.

Under normal conditions, the rubber magnetic ring and the hub are simply attached through industrial glue, the rubber magnetic ring is exposed to the air for a long time, wet and high-temperature weather is met, the adhesive force of the glue to the rubber magnetic ring is reduced, the fixing effect of the rubber magnetic ring is affected, and the possibility that the rubber magnetic ring falls off can occur in the past for a long time.

According to the utility model, the reinforcing plate and the mounting plate are additionally arranged, so that the rubber magnetic ring is tightly attached to the iron piece framework, and the rubber magnetic ring is not easy to fall off.

Disclosure of utility model

The purpose of the utility model is that: an ABS magnetic ring assembly for an automobile hub unit is provided to solve the above-mentioned technical problems in the prior art.

According to the above purpose, the basic technical scheme of the utility model is as follows: an automobile hub unit ABS magnetic ring assembly comprises an annular iron member framework and a rubber magnetic ring arranged on one surface of the iron member framework, wherein the other surface of the iron member framework is fixedly arranged on a hub, and a fixing plate is arranged on one side, far away from the iron member framework, of the rubber magnetic ring;

The rubber magnetic ring consists of a pressed ring and a working ring, the working ring is fixed on one surface of the pressed ring, a plurality of bosses are arranged on the other surface of the pressed ring in an equidistance and surrounding mode, first grooves corresponding to the pressed ring are formed in the iron piece framework, and a plurality of second grooves matched with the bosses are formed in the first grooves in a surrounding mode.

Further, the fixing plate is in a ring shape, and the fixing plate is sleeved outside the working ring.

Further, a plurality of mounting holes are formed in the fixing plate in a surrounding and penetrating mode, positioning holes corresponding to the mounting holes are formed in the iron piece framework, and the fixing plate and the iron piece framework are fixedly connected through the positioning holes.

Compared with the prior art, the utility model has the advantages and beneficial effects that:

1. according to the utility model, the reinforcing plate and the mounting plate are additionally arranged, so that the rubber magnetic ring is tightly attached to the iron piece framework, the iron piece framework is not easy to fall off, and the stability of a product is improved;

2. According to the utility model, the prismatic second groove is arranged in the first groove, and the boss matched with the second groove is additionally arranged at the rear side of the rubber magnetic ring, so that the contact area between the rubber magnetic ring and the iron piece framework is increased, and the stability of the whole structure is further ensured.

FIG. 1 is a schematic perspective view of the product of the present utility model;

FIG. 2 is a schematic diagram of a first explosion of the product of the present utility model;

FIG. 3 is a second exploded view of the product of the present utility model;

In the figure:

1. An iron member skeleton; 2. a fixing plate; 3. a first groove; 4. a second groove; 5. a rubber magnetic ring; 6. a boss; 7. a working ring; 8. a compression ring; 9. and (5) mounting holes.

Detailed Description

Referring to fig. 1 to 3, which are schematic structural views of an embodiment of an ABS magnetic ring assembly of an automobile hub unit according to the present utility model, the ABS magnetic ring assembly of an automobile hub unit includes an iron member frame 1 having a circular ring shape and a rubber magnetic ring 5 disposed on one surface of the iron member frame 1, and the other surface of the iron member frame 1 is fixedly mounted on a hub;

Further, as shown in fig. 2, it is worth explaining that: the rubber magnetic ring 5 is composed of a compression ring 8 and a working ring 7, the working ring 7 is fixed on one surface of the compression ring 8, a plurality of bosses 6 are equidistantly and circumferentially arranged on the other surface of the compression ring 8, a first groove 3 corresponding to the compression ring 8 is formed in the iron piece framework 1, and a plurality of second grooves 4 matched with the bosses 6 are formed in the first groove 3;

because the first groove 3 matched with the compression ring 8 and the second groove 4 matched with the boss 6 are arranged on the iron piece framework 1, the rubber magnetic ring 5 is restrained in multiple directions, and when the rubber magnetic ring 5 is attached to the iron piece framework 1, the rubber magnetic ring 5 is not movable and also not rotatable, and has stability.

When the rubber magnetic ring is installed, firstly, glue is smeared in the first groove 3 and the second groove 4, the rubber magnetic ring is installed in the first groove 3 and the second groove 4, and the rubber magnetic ring 5 is clamped and firmer due to the arrangement of the first groove 3 and the second groove 4.

Further, as shown in fig. 2, it is worth explaining that: a fixed plate 2 is arranged on one side of the rubber magnetic ring 5, which is far away from the iron piece framework 1, and the fixed plate 2 is annular and sleeved outside the working ring 7;
