Abstract

An anti-locking brake system for a motorcycle comprising of dual discs of differing diameters, wherein one disc is smaller than the other having callipers and pistons arranged at different radial angles and lengths from the hub.

Description

I
ANTI LOCK BRAKES FOR MOTOR CYCLE
An automotive disc brake, with multi piston arrangements for motor cycles
BACKGROUND
High performance motor cycles are frequently provided with brake disc rotors on either side of the front wheel. Twin discs assist with the provision of high levels of braking force, and anti-locking may be provided by means of a wheel speed sensor connected to an ECU (electronic control unit) and a modulator which reduces pressure just before the wheel stops turning. Prior art modulation, effectively applies and releases the brake rapidly to keep the brake from locking, and the tyre from skidding.
The larger the disc and hence the radial distance of the piston location, which is the point of friction, the more friction created, and the more braking force provided. Consequently, where say a fifteen inch disc provides adequate brake power on a good road surface, the same may be too powerful and prone to locking on a surface which is wet or provides less grip for the tyre, and in such conditions, a fourteen inch disc or an eleven inch disc may be more appropriate.
DESCRIPTION
This invention refers to prior applications, 1309903.1 which concerns the radial angle of the piston (friction point) on any motor vehicle, and 1312062.1 which concerns the radial distance of the piston, on motor vehicles generally, and 1322148.6 which concerns inverted discs and dual discs of different diameter.
In this invention, there are discs of different diameter on either side of the front wheel. Such an arrangement readily accommodates piston location and therefore the point of friction at different radii. When the brakes are applied, according to the set up of the ECU and modulator, either the calliper on the larger disc is engaged, or both are engaged. When the wheel speed sensor detects rapid deceleration, intimating that lock-up is imminent, the calliper on the larger disc is released, while pressure is transferred or retained to the calliper on the smaller disc, operating at a shorter radius with less friction and less braking force, thereby avoiding lock-up.
Pressure may be returned to the larger disc by a short period of time programmed at the ECU, with modulation continuing between the larger disc and the smaller disc.
Modulation between pistons at different radii, may be used in conjunction with modulation between pistons located at different radial angles, employed to Unit forward weight transfer. Disc rotors can be mounted on the hub as is common, or inverted and mounted on the wheel rim.
Examples of the invention will now be described with reference to the accompanying drawings; In fig. 1 the near side and offside of a front wheel are shown, where A is the tyre B the wheel rim and C the forks. D is the larger diameter disc and E the smaller diameter disc.
Fig. 2 represents an alternative arrangement where the discs are inverted and mounted directly to the wheel.
