Abstract

The invention relates to brake regulator devices making it possible to adjust the power as a function of the load by eliminating the drawbacks due to the instantaneous variations in the attitude of the vehicle. It comprises a spring providing the link between the regulator and the axle of the wheels 1 and a damper which defers the action of the spring 2. The beneficial application of the invention is that it provides braking whose efficiency is not adversely affected by the instantaneous movements of the bodywork of the vehicle as it drives.

Description

La présente invention concerne les dispositifs de freinage dont l'action est corrigée en fonction de la charge du véhicule. The present invention relates to braking devices whose action is corrected as a function of the vehicle load.

Les dispositifs connus utilisant cette correction voient leur effet contrarié par plusieurs facteurs,par exemple: a) les inégalités de la route. Known devices using this correction see their effect thwarted by several factors, for example: a) road unevenness.

b)le profil de la route (le fait que la voiture circule sur une voie montante ou descendante).b) the profile of the road (whether the car is traveling on an uphill or downhill lane).

c)l'action naturelle du freinage qui a tendance à faire piquer l'avant de la voiture,délestant l'arrière et chargeant fictivement l'avant,...etc. c) the natural action of braking which tends to cause the front of the car to sting, shedding weight at the rear and fictitiously loading the front, ... etc.

Le dispositif,objet de cette invention,a pour but de neutraliser les variations instantanées de cette correction.The object of this invention is to neutralize instantaneous variations in this correction.

Ce dispositif consiste à faire la liaison entre la position des roues et
le répartiteur fixé à la carrosserie ,ou inversement ,à l'aide d'une liaison soupple ,un ressort par exemple.This device consists in making the connection between the position of the wheels and
the distributor attached to the bodywork, or vice versa, using a Apple connection, a spring for example.

Les mouvements dus à la position de la carrosserie par rapport à la position des roues étant supprimés par un système d'amortissement dont le réglage du temps de réponse permet de maintenir pratiquement , sans variation pendant plusieurs secondes , la position de la commande du répartiteur.The movements due to the position of the body relative to the position of the wheels being suppressed by a damping system whose adjustment of the response time makes it possible to maintain practically, without variation for several seconds, the position of the distributor control.

Ainsi, quelques soient les variations de la position des roues par rapport à la carrosserie, pour les cas a , b et c cités à titre :'exemple mais non limitatifs, la puissance de freinage ne subira plus de variations instantanées venant contrarier le réglage du système.Thus, whatever the variations in the position of the wheels with respect to the bodywork, for the cases a, b and c cited as: 'example but not limiting, the braking power will no longer undergo instantaneous variations coming to thwart the adjustment of the system.

L'efficacité du freinage restera constante et fonction de la charge.Braking efficiency will remain constant and dependent on the load.

Le dessin annéxé représente le dispositif, objet de ce brevet. The appended drawing represents the device which is the subject of this patent.
