  • Patent number: 7389859
    Abstract: A golf car having a hydraulic fluid brake system. The hydraulic fluid brake system is implemented as a disk brake system which is responsive to hydraulic fluid pressure generated from a master cylinder. A brake pedal and associated linkage provides input to a master cylinder to generate a hydraulic fluid pressure to control a brake caliper assembly. The brake pedal has a range of travel, where a first portion of the range defines a service mode of operation and a second portion of the range defines a parking mode of operation. In the parking mode of operation, the brake pedal and linkage engages a detent to maintain application of the brake to provide a parking mode of operation. An accumulator in the brake system provides an input force to maintain hydraulic fluid pressure sufficient to retain a parking mode of operation.

  • Patent number: 7357229
    Abstract: An electromagnetic shock absorber according to the present invention has a shock absorber body 1 which makes telescopic motion in response to an input from outside. The shock absorber body 1 comprises a ball screw mechanism 15, which converts the telescopic motion into rotary motion and is composed of a ball nut 16 and a screw shaft 17, and power transmitting sections 13 and 24 having elastic bodies which transmit the rotary motion of the ball screw mechanism 15 to a rotary shaft 11 of a motor 10 while shifting a transmission phase when transmission torque of the rotary motion is changed. The motor 10 generates electromagnetic resistance to oppose against rotations which input into the rotary shaft 11. Thus, vibration or the like which inputs into the shock absorber body 1 from outside is damped by the electromagnetic resistance of the motor 10.

  • Patent number: 7350776
    Abstract: A fluid-filled type vibration-damping device having an elastic rubber film partially defining a primary fluid chamber at one surface and partially defining a pressure action chamber. The pressure action chamber varies its pressure under control so that the elastic rubber film changes its elasticity to change damping characteristics of the device. To give sufficient recovery force for the elastic rubber film, the elastic rubber film includes a plurality of thick reinforcing ribs circumferentially spaced apart from one another and extending in a radial direction from an outside peripheral edge over a length not reaching a center so that areas situated between pairs of adjacent reinforcing ribs constitutes thin portions formed by a thin rubber elastic body, while the center portion of the elastic rubber film situated between distal ends constitutes a bowed center portion thinner than the reinforcing ribs and convex towards the pressure action chamber.

  • Patent number: 7344129
    Abstract: A damping method for a hybrid vehicle in which a power unit consisting of an engine and a motor is supported in a vehicle body frame via an active vibration isolation support system includes: a step of firstly damping vibration of the power unit by the active vibration isolation support system; and a subsequent step of controlling operation of the motor to damp vibration that has not been eliminated by the active vibration isolation support system. Therefore, it is possible to prevent the damping effect from being degraded by interference between the damping control by the active vibration isolation support system and the damping control by the motor, and to reduce the total power consumption by preferentially operating the active vibration isolation support system which has low power consumption, and secondarily operating the motor which has high power consumption.
