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...

Problems solved by technology

The structures described in Patent Documents 7 to 12 have been conventionally known as structures for preventing the occurrence of the creep, but the actual situation is that the matter of improving the reliability of rotation speed detection in a two-wheeled vehicle has not been considered before. , utilizing a configuration designed to prevent the occurrence of such creep

[0009] In addition, the sealing plate with magnetic encoder in this rolling bearing with speed detection device is composed of skeleton, sealing lip and magnetic encoder, but the sealing lip and magnetic encoder cannot be attached and fixed to the skeleton in one process at the same time. Therefore, the process is complicated and processing time is required

This problem hinders the cost reduction of the wheel support structure of the motorcycle using the rolling bearing with the rotational speed detecting device.
