Abstract
Description
La présente invention a pour objet un pousse-The subject of the present invention is a pusher
pédale pneumatique.pneumatic pedal.
Il concerne le domaine industriel et commercial de la fabrication et de la diffusion d'outillage destiné avant tout à l'équipement des ateliers appelés à assurer la maintenance et l'entretien des véhicules routiers, et peut convenir à tous les types It concerns the industrial and commercial field of the manufacture and distribution of tools intended above all for the equipment of workshops called to ensure the maintenance and upkeep of road vehicles, and can be suitable for all types
de voitures ou de camions.of cars or trucks.
Lors du montage de roues sur un véhicule, par exemple en cas de remplacement des pneumatiques ou de garnitures de freins, les écrous de fixation doivent être serrés au moyen d'une clé dynamométrique pour assurer un maintien optimal. Les fabricants de pneumatiques recommandent en général d'effectuer cette opération sans que les roues ne soient en contact avec le sol, ce qui impose de pouvoir actionner la pédale de frein pendant le serrage. Par ailleurs les systèmes de freinage des véhicules routiers, sauf certains poids lourds, sont aujourd'hui presque toujours de type hydraulique. En outre, un nombre croissant de véhicules comportent un embrayage hydraulique dont le circuit est similaire à celui des freins. Les circuits de freinage ou d'embrayage nécessitent un remplacement périodique du liquide assurant la transmission de l'énergie. Cette opération s'effectue au moyen d'appareils dont les plus courants fonctionnent par pression pour permettre le transfert du liquide dans le circuit, ces appareils étant généralement raccordés au réservoir du circuit, les vis de purge situées au niveau des récepteurs (étrier ou cylindre de roue) devant être ouvertes pour permettre l'écoulement du liquide usagé. D'autres appareils fonctionnent par aspiration et se branchent directement sur les vis de purge des circuits. Pour pouvoir accéder aux vis de purge le remplacement du liquide s'effectue généralement en When mounting wheels on a vehicle, for example when replacing tires or brake linings, the fixing nuts must be tightened with a torque wrench to ensure optimum support. Tire manufacturers generally recommend carrying out this operation without the wheels touching the ground, which means that the brake pedal must be able to be applied during application. In addition, the braking systems of road vehicles, except for certain heavy goods vehicles, are almost always hydraulic today. In addition, an increasing number of vehicles have a hydraulic clutch whose circuit is similar to that of the brakes. The braking or clutch circuits require periodic replacement of the fluid ensuring the transmission of energy. This operation is carried out by means of devices, the most common of which operate by pressure to allow the transfer of the liquid in the circuit, these devices being generally connected to the reservoir of the circuit, the bleed screws located at the level of the receivers (bracket or cylinder wheel) to be opened to allow the used liquid to drain. Other devices operate by suction and are connected directly to the circuit bleed screws. To be able to access the bleed screws, the replacement of the liquid is generally done by
plaçant le véhicule sur un pont élévateur. placing the vehicle on a lift.
Durant le transfert du liquide de freinage, il est souhaitable de maintenir la pédale de frein légèrement enfoncée, ou de l'actionner à plusieurs reprises afin de faciliter la purge et l'évacuation de l'ancien liquide. De même, dans le cas du circuit d'embrayage, il est recommandé d'actionner la pédale During the transfer of the brake fluid, it is desirable to keep the brake pedal slightly depressed, or to actuate it several times in order to facilitate the bleeding and the evacuation of the old fluid. Similarly, in the case of the clutch circuit, it is recommended to operate the pedal
pendant la purge.during the purge.
En raison de ce qui précède, les opérations de montage des roues sur un véhicule ou de purge des circuits de freinage et d'embrayage sont très souvent exécutées par deux personnes, l'une à l'extérieur du véhicule pour effectuer le serrage des écrous de roues ou manoeuvrer l'appareil de purge, et une seconde personne à l'intérieur pour actionner la pédale de frein ou d'embrayage. I1 existe toutefois des pousse-pédales mécaniques, mais ces appareils ne peuvent pas être Due to the above, the operations of mounting the wheels on a vehicle or bleeding the braking and clutch circuits are very often carried out by two people, one outside the vehicle to tighten the nuts. wheels or operate the bleeding device, and a second person inside to operate the brake or clutch pedal. There are, however, mechanical pedal switches, but these devices cannot be
manoeuvrés de l'extérieur du véhicule. operated from outside the vehicle.
Le dispositif selon la présente invention a pour objectif de remédier à cet état de choses. Il permet en effet à un opérateur seul de piloter aisément à distance, de l'extérieur du véhicule, la manoeuvre de la The device according to the present invention aims to remedy this state of affairs. It allows a single operator to easily control the operation of the
pédale de frein ou d'embrayage.brake or clutch pedal.
