Abstract:
L'invention se rapporte à un système de freinage (1) d'un véhicule, comprenant une pédale d'actionnement (2) montée pivotante dans un pédalier (7), et un dispositif de commande (3) de freins, ladite pédale (2) interagissant avec une tige d'actionnement (10) solidarisée audit dispositif (3), de sorte que la mise en rotation de la pédale (2) autour du pédalier (7) au moyen d'une pression exercée sur ladite pédale (2), entraine un déplacement linéaire de ladite tige (10) le long de son axe longitudinal pour déclencher ledit dispositif de commande (3). La principale caractéristique d'un système de freinage selon l'invention, est que la pédale (2) est dotée d'une protubérance arrondie (17), l'interaction entre la pédale (2) et la tige (10) étant réalisée au moyen d'une mise au contact de ladite protubérance (17) avec ladite tige (10), provoquée par une pression sur ladite pédale (2).
Abstract:
An adjustment device (4) for the release position of an operation element (8) of a brake. The device (4) comprises an articulated rod (20) hinged in a fulcrum (16) and connected in rotation to the operation element (8). The articulated rod (20) comprises an adjustment end (28) provided with a pin (29) having an adjustment hole (32) at least partly threaded and engaged with a threaded portion (48) of a push rod (40), operatively connected to operation means (44) of the brake. The device comprises anti-rotation means (74, 78), suitable for locking in rotation the push rod (40), relative to the adjustment axis (Y-Y).
Abstract:
The invention relates to a parking brake device (30), in particular handbrake device, for a vehicle having at least one electric machine (6) in a drive train (10) and at least one electric energy store (11), having an activation lever (1) which is connected to at least one parking brake (8) via a transmission means (9) which is preferably formed by means of a cable or a rod. In order to recover the braking energy, there is provision for at least one sensor (3) which is connected to an electric control unit to be provided for sensing the travel or rotary angle () of the activation lever (1), wherein the electric machine (6) can be operated as a generator by means of the control unit (4) and an electric braking torque can be applied to the drive train (10).
Abstract:
The invention relates to a system for controlling the ignition of a motor vehicle, which system comprises: a control member (2) which is manoeuvrable between a switched-off position, in which the control member (2) keeps the ignition switched off, and a switched-on position, in which the control member (2) keeps the ignition switched on, and a manually manoeuvrable operating member (3), by means of which the control member (2) is manoeuvrable between switched-off position and switched-on position, and - an electronic control unit (4) that is adapted to activate a retention function under predetermined conditions, the control unit, when the retention function is activated, retaining the control member (2) in switched-on position and thereby preventing the control member from being manoeuvred from switched-on position to switched-off position under the effect of the operating member (3). The invention also relates to a corresponding method for controlling the ignition of a motor vehicle.
