Abstract
The utility model discloses a passenger vehicle wheel hub unit assembly which comprises a flange outer ring, two inner rings, two rolling bodies, two retainers and a magnetism encoder. Double-row inner grooves are arranged at the inner side of the flange outer ring, outer grooves are respectively arranged at the outer sides of the two inner rings, the rolling bodies are installed in the retainers and arranged between the flange outer ring and the inner rings, and the magnetism encoder is installed on the end surface of the flange outer ring. The magnetism encoder is installed on the end surface of the flange outer ring of the utility model, periodically changed magnetic field is formed during the running of the outer ring of a wheel hub, the magnetic field is exerted on a sensing head to output quasi sinusoid voltage signals, and to finally reflect the change of the wheel speed after being processed. Because the magnetism encoder has stronger magnetism, even if the wheel speed is very low, the sensor can induce higher effective voltage, thereby being very sensitive to the reaction of the wheel speed. Simultaneously, the utility model has good axial radial direction bearing capacity, to ensure that the wheel of a vehicle has very high reliability when the vehicle is driven on the crooked road or emergency braking is performed.
Description
[technical field]
The utility model relates to auto parts and components, relates in particular to passenger car hub assembly.
[background technique]
At present, the pivoting support of small-sized passenger car wheel has mostly adopted the hub assembly structure, and this structure not only can be simplified installation procedure, dwindles installing space, has guaranteed that effectively bearing bearing strength and rigidity fully satisfy the automobilism requirement simultaneously; Particularly along with development of electronic technology, on hub also common configuration various forms of wheel speed sensors, and wheel speed signal coupling device, the velocity information of wheel running is sent to control system directly, exactly, can prevent effectively automobile when emergency braking wheel by locking phenomenon, thereby the Safety performance of automobilism is improved greatly.
But when wheel speed was low, the induced voltage of generation was just less, and making sensor is not very sensitive to the reaction of wheel speed, and the Safety performance of automobile is had certain influence.Simultaneously, its axially and radially bearing capacity also be not very high, it is not very high making the reliability of vehicle wheel when bend and Emergency braking.
[summary of the invention]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of super passenger car hub assembly, and sensor is to the reaction sensitivity of wheel speed, axially and radially the bearing capacity height.
For achieving the above object, the utility model proposes a kind of passenger car hub assembly, comprise flange outer ring, two inner rings, two rolling elements, two retainers and magnetic encoder, inboard, described flange outer ring is provided with raceway groove in the biserial, two inner ring outsides are respectively equipped with outer raceway groove, rolling element is installed in the retainer, and is arranged between flange outer ring and the inner ring, on the end face of flange outer ring magnetic encoder is housed.
As preferably, also comprise Sealing, described Sealing is arranged between the end face and inner ring of flange outer ring.
As preferably, described magnetic encoder is the stainless steel insert of coated magnetic material.
As preferably, described retainer adopts Reinforced Nylon to make.
As preferably, the outer raceway groove of raceway groove and inner ring adopts big wrapping angle structure in the biserial of described flange outer ring.
The beneficial effects of the utility model: the utility model is equipped with magnetic encoder on the end face of flange outer ring, in the process of wheel hub outer ring running, form periodically variable magnetic field, just export the quasi-sine-wave voltage signal after acting on sensing head, through handling, finally reflect the variation of wheel speed.Because magnetic encoder itself has stronger magnetic, so even when wheel speed is very low, sensor also can be sensed a higher effective voltage, thereby very sensitive to the reaction of wheel speed.The outer raceway groove of raceway groove and inner ring adopts big wrapping angle structure in the biserial of flange outer ring, constitute biserial angular contact ball structure, realized good axially and radially bearing capacity, particularly bigger axial carrying capacity makes vehicle wheel when bend or Emergency braking that very high reliability all be arranged.Reasonably be provided with the reinforcement ledge structure on the flange outer ring, can economical with materials and alleviate deadweight.
Feature of the present utility model and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
Fig. 1 is the structural representation of the utility model passenger car hub assembly.
[embodiment]
Fig. 1 is the structural representation of the utility model passenger car hub assembly.Passenger car hub assembly, comprise flange outer ring 1, two inner rings 2, two rolling elements 3, two retainers 4 and magnetic encoders 5,1 inboard, described flange outer ring is provided with raceway groove in the biserial, two inner ring 2 outsides are respectively equipped with outer raceway groove, rolling element 3 is installed in the retainer 4, and be arranged between flange outer ring 1 and the inner ring 2, magnetic encoder 5 is housed on the end face of flange outer ring 1.Raceway groove constitutes the apron space of two row rolling elements respectively in the biserial of outer ring, unit 1 with two inner rings, 2 outer raceway grooves, and rolling element 3 is installed in the retainer 4, is guided along with rotate inner ring 2, flange outer ring 1 by retainer 4.
Described magnetic encoder 5 is the stainless steel insert of coated magnetic material, can form tens ofly to the N-S magnetic pole simultaneously, and magnetic encoder 5 is installed in the end, outer ring, cooperates tightly, guarantees the coupling precision with sensing head.In the process of wheel hub outer ring running, form periodically variable magnetic field like this, just export the quasi-sine-wave voltage signal after acting on sensing head,, finally reflect the variation of wheel speed through handling.Because magnetic encoder 5 itself has stronger magnetic, so even when wheel speed is very low, sensor also can be sensed a higher effective voltage, thereby very sensitive to the reaction of wheel speed.
Also comprise Sealing 6, described Sealing 6 is arranged between the end face and inner ring 2 of flange outer ring 1.Strengthen the sealing of whole hub.Described retainer 4 adopts Reinforced Nylon to make.
The outer raceway groove of raceway groove and inner ring 2 adopts big wrapping angle structure in the biserial of described flange outer ring 1, constitute biserial angular contact ball structure, realized good axially and radially bearing capacity, particularly bigger axial carrying capacity makes vehicle wheel when bend or Emergency braking that very high reliability all be arranged.Reasonably be provided with the reinforcement ledge structure on the flange outer ring 1, can economical with materials and alleviate deadweight.Have the construction bolt hole on the flange outer ring 1, connect automobile rim, the chassis suspension system then is connected with hub by semiaxis.
China's passenger car hub structure has further been enriched in the application of this hub assembly, is the further lifting of hub series product technology, has extraordinary economic benefit and social benefit.
The foregoing description is to explanation of the present utility model, is not to qualification of the present utility model, any structure after the utility model simple transformation is all belonged to protection domain of the present utility model.
