AI Technical Summary

Technical Problem

Conventional vehicle wheel support devices require separate components and assembly processes for drive wheels and driven wheels to prevent foreign matter from adhering to sensors, leading to increased complexity and costs.

Method used

A vehicle wheel support device that integrates a cap with deflector functionality, allowing it to serve as both a protective cap for the hub bearing and a deflector for the sensor, thus preventing foreign matter from adhering to the sensor and enabling the use of common components across both types of wheels.

Benefits of technology

The integrated cap-deflector design effectively prevents foreign matter from adhering to the sensor, allowing for common hub carriers, sensors, wire harnesses, and connectors across both drive and driven wheels, simplifying production and assembly while maintaining detection accuracy.

Abstract

To provide a vehicle wheel support device that can achieve commonization of components.SOLUTION: A vehicle wheel support device 10 comprises: a hub bearing 12 which rotatably supports a hub shaft 124 which is a rotary shaft body connected to a wheel W; a hub carrier 11 which has a storage hole part 111 for accommodating a part of the hub bearing 12, and supports the hub bearing 12 in the state of being accommodated in the storage hole part 111; a sensor 13 which is fixed to a fixed part 112 of the hub carrier 11 in the state that a detection part 131 for detecting a rotation state projects from an inner peripheral surface of the storage hole part 111 so as to detect the rotation state of an inner ring 122 around an axis thereof; and a cap 15 which prevents foreign matters from entering the inside of the hub bearing 12 from a space S that permits entry of the foreign matters, and with which a deflector member 15A, which is at least a part of a deflector 14 for isolating the detection part 131 in the space S, is formed integrally.SELECTED DRAWING: Figure 2
