Description
Technical field
The utility model relates to a kind of vehicular spare parts, is a kind of isostructural improvement of hub-bearing unit to integral sensor between the band row specifically.
Background technology
Present hub-bearing unit is the parts in a kind of automobile suspension system, and it generally is the support as automotive wheel, possesses the basic function of transfer torque.But common hub-bearing unit assembling more complicated can't play the leak free effect, and uncontrollable wheel carries out speed setting during vehicle brake.
Someone improves at above-mentioned deficiency, Chinese patent discloses a kind of automobile non-driving wheel bearing-hub assembly (publication number: CN2451368Y), it comprises flange, roller provided thereon and the wheel hub inner ring and the wheel hub outer ring that place outside it, the flange of wheel hub inner ring rear end is provided with regulating tank, which is provided with regulating block, and be provided with support ring in the rear end of regulating tank.Though but it has realized inner self-lubricating to a certain extent, wheel hub in-to-in self-lubricating effect is bad, and is not lifelong self-lubricating.
As mentioned above, there is following deficiency in prior art: structure is compact inadequately, reliability is not high and do not have excellent sealing performance and lifelong self-lubricating effect.
Summary of the invention
The utility model has solved compact inadequately, the not high problem that reaches of reliability of structure that prior art exists, the utility model has also solved the problem that does not have excellent sealing performance and lifelong self-lubricating effect that prior art exists, and provides a kind of structural arrangement compactness, reliability is high and have good sealing property and have the hub-bearing unit of integral sensor between the band row of lifelong self-lubricating effect.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of hub-bearing unit with integral sensor between row, comprise flange, gear ring and sensor, be connected with the wheel hub inner ring on the described flange, the inner ring periphery is connected with the outer ring, be provided with rolling body between the flange of band inner ring and the outer ring, the inboard, outer ring is provided with the double channel of symmetry, the contact surface in its cross section has the arc surface suitable with rolling body, it is characterized in that described gear ring is located on the flange axle journal between the two row rolling bodys, the outer ring in the described gear ring outside is provided with inclined hole; Described inclined hole is provided with the sensor probe suitable with it, leaves the gap between described sensor probe and the gear ring outer face; Described sensor is integral sensor between row.Rolling body can be steel ball, the integral sensor keystone configuration mainly is made up of sensor module between row, sensor probe inserts inclined hole (being gauge hole), and leave certain clearance between the gear ring, connect the sensor wire harness behind the sensor probe, when vehicle produces speed, flange rotates, gear ring rotates thereupon, by cutting magnetic line, produce and the output electric signal, the frequency of the ac signal of output is relevant with wheel velocity with amplitude, these signals offer the ABS computerized control system by the sensor wire harness, thus control anti-lock and carry out anti-slip regulation during wheel brake.The use of integral sensor structure between row has changed the integral structure of hub-bearing unit, makes sensor construction place hub-bearing unit, has reduced unit volume greatly, and it is compact that whole unit is arranged, the reliability height.
The utility model is skillfully constructed, and the setting by integral sensor between row makes the utility model have following characteristics compared with the prior art:
1, structural unitization, layout compactness, volume is little, has alleviated overall weight, and operation and maintenance is convenient;
2, hermetically-sealed construction protection against dust, good airproof performance have lifelong self-lubricating;
3, prolong service life, improved reliability, rigidity and speed ability, be applicable to drive hub bearing unit structure.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model:
Fig. 2 is the right TV structure scheme drawing of Fig. 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, Fig. 2, a kind of hub-bearing unit of this example with integral sensor between row, comprise flange 1, gear ring 2 and sensor 5, described sensor 5 is integral sensor between row, it mainly contains sensor module and forms, be connected with wheel hub inner ring 7 on the described flange, the inner ring periphery is connected with outer ring 8, be provided with rolling body 6 between the flange of band inner ring and the outer ring, the inboard, outer ring is provided with the double channel of symmetry, the contact surface in its cross section has the arc surface suitable with rolling body, described gear ring 2 is located on flange 1 axle journal between the two row rolling bodys 6, the outer ring 8 in described gear ring 2 outsides is provided with inclined hole 3, and described inclined hole 3 is provided with the sensor probe suitable with it 4.Wherein, the end face of wheel hub outer ring 8 is provided with several threaded shank holes, and rolling body 6 is a steel ball, and by retainer 9 fixed positions, a side matches with the double channel of wheel hub outer ring 8, and opposite side is suitable with flange 1 double channel of band inner ring 7.Be connected with seal ring assembly 10 between wheel hub outer ring 8 and the flange 1 neck seal diameter, seal ring assembly is by the sealing bore interference fit of skeleton and wheel hub outer ring 8, has many lips rubber sealing structure on the skeleton, many lips rubber contacts with flange 1 sealed step, and poted assemblies plays the effect of exclusion seal, lifelong self-lubricating to whole wheel hub structure.
