Wheel support structure for two-wheeled vehicle

Abstract

A wheel support structure for a two-wheeled vehicle, configured either in such a manner that an encoder mounting plate is mounted to an end of the outer ring of one rolling bearing in the axial direction, the end being located on the other rolling bearing side, and a magnetic encoder for detecting rotational speed is attached and affixed to the inner peripheral surface of the cylindrical section of the encoder mounting plate, the cylindrical section extending outward from the outer ring in the axial direction, or in such a manner that the magnetic encoder for detecting rotational speed is attached and affixed to a side surface of a slinger, the side surface of the slinger being located on the other rolling bearing side, the slinger being mounted to the end in the axial direction and having an inner diameter-side end surface located close to the outer peripheral surface of the inner ring to form a labyrinth gap. Preferably, a rotation restraining member is engaged with the outer peripheral surface of the outer ring which is a rotation-side raceway ring, and the rotation restraining member and the inner peripheral surface of a hub which is a rotation-side member are engaged with each other.

Description

technical field [0001] The present invention relates to a structure for supporting wheels of two-wheeled motor vehicles such as motorcycles and scooters, and more particularly to a wheel support structure for two-wheeled motor vehicles equipped with a rotational speed detection device for the wheels. Background technique [0002] As a device for stabilizing the running state of an automobile, an anti-lock braking system (ABS) is widely used. This ABS has already been widely used in the field of four-wheeled vehicles, but in recent years, it has also begun to be adopted in the field of two-wheeled motor vehicles. In order to control the ABS, it is necessary to obtain the rotational speed of the wheel, and thus a technique of incorporating a rotational speed detection device into a rolling bearing for rotatably supporting the wheel to the suspension device has been widely practiced. [0003] However, the structure of the rotational speed detection device for a four-wheeled ve...
