rampa de esferas; esfera e rampa Explanation: Vi algumas imagens na Internet e me parece que podem ser duas coisas : Mecanismo de rampa de esferas Mecanismo de esfera e rampa -------------------------------------------------- Note added at 33 minutos (2015-12-21 14:58:14 GMT) -------------------------------------------------- Achei um site que explica como funciona esse sistema de travamento (ball and ramp): http://www.ford-taurus.org/taurusinfo/Features/ParkBrake.pdf "Ball-and-Ramp Operation. Ford’s floating caliper rear disc brakes are the most common example of the ball-and-ramp parking brake mechanism (Figure 8-17). The caliper lever is attached to a shaft inside the caliper that has a small plate on the other end. Another plate is attached to a thrust screw inside the caliper piston. The two plates face each other, and three steel balls separate them. When the parking brake is applied, the caliper lever rotates the shaft and plate. Ramps in the surface of the plate force the balls outward against similar ramps in the other plate. As the plates move farther apart, the thrust screw forces the piston outward. The thrust screw cannot rotate because it is keyed to the caliper. The piston then applies the inboard brake pad, and the caliper slides as it does for service brake operation and forces the outboard pad against the rotor. When the caliper piston moves away from the thrust screw, an adjuster nut inside the piston rotates on the screw to take up clearance and provide self-adjustment. A drive ring on the nut keeps it from rotating backward." Essas imagens mostram as rampas e as esferas: https://www.google.com.br/imgres?imgurl=http://www.cruisercu... https://www.google.com.br/imgres?imgurl=http://cr4.globalspe... -------------------------------------------------- Note added at 50 minutos (2015-12-21 15:14:51 GMT) -------------------------------------------------- Como se trata de mais de uma rampa e mais de uma esfera, eu ficaria com a segunda opção, mas colocando-a no plural: mecanismo de rampas e esferas -------------------------------------------------- Note added at 2 horas (2015-12-21 16:35:58 GMT) -------------------------------------------------- Mais uma referência: http://www.fatecsantoandre.com.br/silva--bezerra.pdf 2.2.1.7.2 Mecanismo de esfera e rampa "A alavanca da pinça é ligada a um eixo que possui uma placa na outra extremidade. Outra placa é ligada a um parafuso de pressão dentro do pistão da pinça. As duas placas são montadas paralelamente, e três esferas de aço as separam. Quando o freio de estacionamento é acionado, a alavanca gira o eixo e a placa...." Não vejo porque manter em inglês se dispomos de recursos para traduzir preservando a ideia central. |
