Description

Motor vehicle hub unit with sensor

Technical Field

The utility model relates to a motor vehicle wheel hub unit specifically is a motor vehicle wheel hub unit of tape sensor.

Background

The hub unit of a motor vehicle, which, in addition to carrying weight and converting power, also carries the function of rotational speed measurement, provides a signal input for the ABS system.

The existing motor vehicle hub unit with a sensor has two structures:

the structure A is shown in figure 1, a double-row tapered roller bearing 2 ' is sleeved on a flange 1 ', a retainer ring 3 ' is arranged at the outer end of an inner ring 21 ' of the double-row tapered roller bearing 2 ', the retainer ring 3 ', the inner ring 21 ' and the flange 1 ' are fixed into a whole by the outer end of the retainer ring 3 ' through a locking nut, a gear ring 4 ' and a sensor 5 ' are arranged at the outer side of the retainer ring 3 ', and the front side of a shell 51 of the sensor 5 ' is in close contact connection with the outer wall of an outer ring 22 ' of the double-row tapered roller bearing 2 ' to.

The structure B is as shown in figure 2, a double-row tapered roller bearing 2 ' is sleeved on a flange 1 ', a groove 11 ' is formed in the flange at the outer end of an inner ring 21 ' of the double-row tapered roller bearing 2 ', two half check rings 6 ' are clamped into the groove without clearance, so that the double-row tapered roller bearing 2 ' is positioned, a gear ring 4 ' and a sensor 5 ' are arranged on the outer part of the half check ring 6 ' of the flange 1 ', and the front side of a shell 51 ' of the sensor 5 ' is in close contact connection with the outer wall of an outer ring 22 ' of the double-row tapered roller bearing 2 ' so as to realize sealing.

In the above two structures, the front end of the housing 51 'of the sensor 5' and the outer ring 22 'are sealed in a manner of fitting and clinging to each other through contact surfaces, so that the sealing effect is poor, muddy water often enters the sensor during use, and the detection precision and the service life of the sensor 5' are seriously affected.

Further, the above a structure is limited by a fixed structure and can be used only in a driving wheel, but occasionally a misapplied product, that is, a product which is fitted into a non-driving wheel, occurs in actual assembly, thereby causing a safety accident.

And for the B structure, generally used for non-driving wheel, simultaneously in order to guarantee the zero clearance assembly, the machining precision requirement of half retaining ring 6' is very high, must carry out the later stage apolegamy, has the problem that production efficiency is low, and the mounting method is complicated, and the quality is difficult to guarantee.

SUMMERY OF THE UTILITY MODEL

To the problem, the utility model discloses a take motor vehicle wheel hub unit of sensor, its outer lane cooperation department at sensor housing and double-row tapered roller bearing is provided with sealed reinforcing structure, and it can effectively promote connection leakproofness between them, prevents that muddy water from getting into in the use to guarantee the normal work of sensor, and can effectively prolong the life of sensor.

The utility model discloses a second design objective has redesigned double-row tapered roller bearing's location structure, makes its structure simplify, has realized the general of drive wheel and non-drive wheel, can make things convenient for customer and manufacturing enterprise's management more.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a motor vehicle wheel hub unit of tape sensor, includes the flange, and the suit is double-row tapered roller bearing, ring gear and sensor on the flange, and the shell front side of sensor is hugged closely with double-row tapered roller bearing's outer lane outer wall and is connected its characterized in that: the sealing structure comprises at least one annular groove formed in the outer ring, and a sealing rubber ring is installed in each annular groove.

Furthermore, the head of the flange is turned outwards and is directly abutted and riveted with the outer end of the inner ring of the double-row tapered roller bearing.

Further, the gear ring and the sensor are arranged on the outer wall of the inner ring.

The utility model discloses outer lane cooperation department at sensor housing and double-row tapered roller bearing is provided with sealed reinforcing structure, and it can effectively promote connection leakproofness between them, prevents that muddy water from getting into in the use to guarantee the normal work of sensor, prolong the life of sensor.

The double-row tapered roller bearing realizes fixed positioning on the flange through riveting of the flange head, is convenient to assemble, ensures the machining precision more easily, realizes the universality of the hub unit assembly of the driving wheel and the non-driving wheel, and can be more convenient for clients and manufacturers to manage.

Detailed Description

As shown in fig. 3, a wheel hub unit of a motor vehicle with a sensor includes a flange 1, a double-row tapered roller bearing 2, a ring gear 4 and a sensor 5 are sleeved on the flange 1, the front side of a housing 51 of the sensor 5 is connected with the outer wall of an outer ring 22 of the double-row tapered roller bearing 2 in a close contact manner, a sealing reinforcing structure 3 is arranged at the matching position of the front side of the housing 51 and the outer ring 22, the sealing reinforcing structure 3 includes at least one annular groove 31 arranged on the outer ring, a sealing rubber ring 32 is installed in each annular groove 31, only one annular groove 31 is arranged in this figure, and two or more annular grooves can be arranged in practice as required.

Above sealed reinforcing structure 3's setting, its connection leakproofness that can effectively promote both prevents that muddy water from getting into sensor 5 in the use to guarantee sensor 5's normal work, prolong sensor 5's life.

The flange 1 is shown with its head 11 turned outwards and riveted directly against the outer end of the inner ring 21 of the double row tapered roller bearing 2.

The double-row tapered roller bearing 2 is fixedly positioned on the flange 1 through riveting of the flange head 11, so that the assembly is convenient, the machining precision is easier to guarantee, the wheel hub unit assembly of the driving wheel and the non-driving wheel is universal, and the management of customers and production enterprises can be facilitated.

Here, the ring gear 4 and the sensor 5 of the present invention are provided on the outer wall of the inner ring 21, considering that the flange 1 does not have an additional installation space reserved at the head 11 thereof.

The above, it is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the technical principles of the present invention to any simple modification, equivalent change or decoration of the above embodiments, still belong to the technical solution of the present invention.
