Abstract

The present invention provides a road holding ability mechanism applied to a motorcycle with two wheels in front. The mechanism may be configured on a three-wheeled motorcycle which has two front wheels and a single rear wheel or on a four-wheeled motorcycle with two front wheels as well as two rear wheels. Under any operating condition, the mechanism enables the two front wheels to offer great road holding ability, that is, to remain stable when moving so as to ensure the motorcycle against rollovers. The present invention includes a simple and innovative structure.

Claims

1. A road holding ability mechanism for the two front wheels of a motorcycle, comprising:

two front wheel brackets for supporting the two front wheels respectively coupled with a connecting arm secured to a connecting base between the connecting arms;

a steering shaft attached to a handlebar of the motorcycle for directing the front wheels to a desired direction of motion, wherein the connecting base and the steering shaft are managed by a control system so as to control the connecting base not only to be able to tilt simultaneously with the steering shaft when the shaft tilts but also to be able to stay fixed in the same place without turning simultaneously with the steering shaft when the shaft performs in-place clockwise or counterclockwise rotation;

two shock absorbers whose buffer action forces are interconnected via a tilting system and each of which has one end pivotally connected with the top surface of the relative connecting arm;

wherein the tilting system further includes an air cell of which the interior is filled with compressed air and of which both ends may respectively touch the side providing the buffer action forces of the shock absorbers, a throttling valve arranged in the middle section of the air cell, and an inflation inlet, and wherein the throttling valve may control the air flowing speed of both ends of the air cell, and moreover, the inflation inlet allows the air to run into the air cell so as to fill the interior of the air cell;

an anchor plate attached to the steering shaft so as to be able to simultaneously operate together with the shaft and arranged with a right steering linkage as well as a left steering linkage which are respectively connected to the relative front wheel bracket; and

an extension plate which is provided in coupling with the connecting base so as to be able to simultaneously perform together with the connecting base and which is configured with a right linkage and a left linkage respectively attached to the relative front wheel bracket.

2. The road holding ability mechanism for the two front wheels of a motorcycle as claimed in claim 1, wherein the shock absorbers are the hydraulic dampers, and the side providing the buffer action forces from the piston rods of the two hydraulic dampers may touch both ends of the air cell of the tilting system.
