Abstract
Official abstract text for this publication.
A front wheel differential lock control system for a straddle-ride type four-wheeled vehicle is provided that can reliably switch a differential locking mechanism into a lock state in a low vehicle-speed state. In an engine provided with a manual transmission having forward five-speed and reverse gears, only in a low gear ratio state (1 st through 3 rd gears) is actuation of a diff-lock actuator permitted to switch a front wheel differential mechanism into a differential lock state. When a diff-lock operation is operated on the time of selection of third-, fourth- or fifth-speed gear, engine rotation number control is exercised to allow an engine rotation number to converge on a predetermined upper limit value. In an engine provided with a start clutch or a torque converter, actuation of the diff-lock actuator is permitted only in a low engine rotation number state where drive force is not transmitted to the front wheels.
First claim
Opening claim text (preview).
What is claimed is: 1. A front wheel differential lock control system for a straddle-ride type four-wheel vehicle, comprising: a differential mechanism for producing a rotational difference between left and right front wheels driven by an engine; an engine rotation number detector, said engine rotation number detector serving to detect an engine rotation number of the engine; a device, disposed in a drive force transmission path between the engine and the differential mechanis…
