Document Type and Number:
WIPO Patent Application WO/2004/106762
Kind Code:
A1
Abstract:
The disclosed invention refers to an innovative semi-automatic clutch, engaged by centrifugal forces induced on lever arms, comprising a drum (2), an elastic ring (3), and a cover (4) including stop guides (5).Additionally, the invention discloses six helical rolls (7) moving on ascending slopes (11), shaped on the surface of the cover (4). Said invention enables the driver of a vehicle to engage first gear of an manual gearbox shaft. Therefore, it is also no longer necessary to disengage a gear during and after stoppage. The outer dimension of said clutch is similar to dry flange clutches commonly used in automobiles today, thus can be interchanged with reasonable effort.

Description:
26Title: "CLUTCH SEMI AUTOMATIC".

Refers the, present invention to an unpublished, functional and innovative clutch automatic semi, through modifications in the plateau, to aid the driver in the exit process and stop of the vehicle, that is, to clamp to 1 st march of the vehicle without the aid of the clutch and when it stops the vehicle, the motor it will continue in normal operation, even if is with a <BR> <BR> <BR> <BR> damped march, therefore the system separates automatically, since the force is exercised by the centrifugal force, I will only stop with the slow march, diminishing the force of the motor.

The present object is destined to allow more useful life for the original exchange of the vehicle, preserving him and making possible the driver more comfort when driving, since through this system, the vehicle won't give "collisions" and only with @ half travel of friction of the pedal it already happens the damp of the marches. It is pointed out that is the one that to 1st march it should be damped without the aid of the clutch, but the process of change of the marches (2nd, 3rd, 4th 5th and rZ, it should usually be made with the help of the clutch.

Your use 11 be of great importance in the chaotic traffic of the great cities, with a great cost benefit, because the system won't need adaptations, since the axis of the clutch will maintain your dimensions and system of original facilities, could be installed in any vehicle model that possesses the conventional system of manual clutch.

With the invention for now proposed, the user, be man or woman, he won't have any fear and he won't need depending of any extra force to damp the marches, to damp to 1st march and to stop the vehicle.

Therefore, it was developed a product that formed an alliance with the fundionality concepts, he/she offers total safety and industrial applicable.

For a perfect visualization of as she comes Me ¢CLUJCH SEMI AUTOMATIC", she is illustrative drawings enclosed, where;

The it presents a view in cut of the helical roll of the object in subject ; The fig. 2-it presents a view superior of the cover of the object in subject The fig. 3-it presents a lateral view in cut of the cover of the object in subject ; The fig. 4 - it presents a view superior of the elastic ring of the object in subject ; The fig. 5 - it presents a lateral view of the roll of the object in subject; The fig. 6 - it presents an illustrative view of the positioning of it fits of the roll of the object in subject ; The fig, 7-it presents a lateral view of the elastic ring of the object in subject ; The fig. 8-it presents a view superior of the plateau of the object in subject ; The fig. 9-ft presents a view superior of the object in subject.

In agreement with the illustrations and in your details, the"CLUTCH SEMI AUTOMATIC" in subject, is characterized by being constituted of a clutch automatic semi (1) possessing a plateau (2), an elastic ring (3) and a cover (4) with month guides (5) with rivets (6), provided of six helical roll (7) with central command (8) and six entrances (9) and internal roll (10) that are moved on a surface of ascending saliency (11) with stocking moon (12) and with internal roll (13); still possessing on the cover (4), deformed weight foils (14) with cavities (15), fixation screws (16), external roll (17), with three fixed helical commands (18); the plateau (2) it is fastened behind the elastic ring (3), provided of sheets of arch spring (19), with levers of fixation of the group (20) with internal spheres (21).

For the advantages that he/she offers and for covering truly of characteristics innovative, the "CLUTCH SEMI AUTOMATIC", gathers the necessary conditions to deserve Patent Invention's Privilege.
