| 摘要 |
An anti-lock brake system for a wheeled vehicle having pressure-operated wheel brakes (26',28') with discrete anti-lock brake pump circuits including a solenoid-operated isolation valve (64',66') for each of the wheel brakes, a pressure hold-and-dump control solenoid valve (92',98') for each wheel brake, and a common attenuator (184) for the discrete anti-lock pump circuits, the attenuator providing sound energy absorption and pressure pulse energy dissipation and comprising an elastomeric element that attenuates pressure pulses in each of the discrete circuits, the attenuator action for one circuit complementing the attenuator action of the other circuit, thereby doubling the attenuator effectiveness and improving noise reduction potential.
