  • Patent number: 5441130
    Abstract: A backlash preventing magnetic apparatus for a transmission for a vehicle having a fixed outer race, and an inner race connected to a driving shaft. A plurality of projections are formed on a circumferential surface of the inner race or outer race. A plurality of rotating bodies are disposed between the outer race and the inner race so that the rotating bodies can be combined with the projections. A permanent magnet is mounted on each of the rotating bodies. An annular plate supporting the rotating body and backlash preventing rollers are disposed between the rotating bodies wherein the backlash preventing roller enables the inner race to rotate in a first direction and prevents rotation in a reverse direction.

  • Patent number: 4770054
    Abstract: Backlash preventing apparatus for a transmission for a vehicle having an outer race fixed to a body, an inner face fixed to a driving shaft, and a bail bearing disposed therebetween. A roller clutch is provided having a plurality of inclined grooves mounted between the outer race and the inner race. A backlash preventing roller is located in the inclined grooves. A first support spring and a support pin are inserted within an inclined spring hole formed adjacent to a corner of the inclined groove. A small roller is inserted into a gap formed between the roller clutch and the inner race, and a second support spring and pin are mounted between the roller clutch and inner race. The backlash preventing apparatus enables the inner race to rotate in a first direction and provides limited backlash rotation in a reverse direction.

  • Patent number: 4590406
    Abstract: An automatic braking control system is capable of automatically maintaining a braking force once a vehicle has been stopped by the driver. The braking force is maintained until the clutch of the vehicle is engaged, at which time the force is automatically released so that the vehicle can be restarted. This system is especially useful for restarting a vehicle which has been stopped on an upward slope. In such a situation, the vehicle is prevented from rolling backwards, as commonly occurs when attempting to resume motion up the slope. The system is also capable of automatically turning off head lights of the vehicle when the vehicle is stopped in order to conserve battery power.

  • Patent number: 4515259
    Abstract: A brake control device for preventing backward movement of a vehicle on an uphill road during operation of the clutch pedal after release of the brake pedal, the device including a cylinder body having oil passages for connection between the master cylinder and the wheel cylinders of the vehicle. A spring biased hollow plunger is reciprocably received within the cylinder body to provide flow communication between the oil passages in a first position thereof when the brake pedal is actuated, and to prevent the oil from returning from the wheel cylinders in a second position thereof when the clutch pedal is actuated upon release of the brake pedal. An electromagnetic switch-activated system moves the hollow plunger from the first position to the second position when the clutch pedal is actuated.
