Abstract

A device capable of enhancing the detection accuracy of a wheel speed detecting device and reducing cost. A wheel speed detecting device for a rear wheel includes a pulsar ring mounted on a rear wheel hub, and a pulse counting sensor mounted on a swing arm. The pulsar ring includes a disc, and pulse detecting holes are formed at a predetermined pitch on a pitch circle drawn at a radially inward circumferential position spaced at a predetermined distance from the outer edge of the disc. The pulse detecting hole is formed in a position on the center side apart from the outer edge of the pulsar ring, leaving the outer edge of the pulsar ring in a circular form. Therefore, it is possible to prevent warpage of the pulsar ring by the outer edge portion if the pulse detecting holes are made by pressing.

Description

technical field [0001] The invention relates to a wheel speed detection device for detecting the rotation speed of a wheel. Background technique [0002] Among motorcycles, some motorcycles are provided with a wheel speed detection device for detecting rotation speeds of front and rear wheels in order to adopt an anti-lock braking system (ABS). As a wheel speed detection device, Japanese Patent Laid-Open No. 8-133154 discloses "Wheel Speed ​​Detection Device on Motorcycle". Hereinafter, this technique will be described in detail using the following figures. [0003] Figure 18 It is a side view of a conventional wheel speed detection device. Next, a wheel speed detection device mounted on a rear wheel of a motorcycle will be described. [0004] In the wheel speed detection device 150, a sensor ring (hereinafter referred to as "pulse generator ring") 153 is mounted on the spoke portion 152 of the rear wheel 151, and a pulse counting sensor 156 (for example, an electromagne...
