Patent number: 9045115Abstract: A rotation of a right wheel (3RR) and a rotation of a left wheel (3RL) of a vehicle are locked respectively by independent parking lock mechanisms (6). Each parking lock mechanism (6) comprises a locking operation prevention mechanism (63c,63d) which mechanically prevents the locking operation of the parking lock mechanism (6) when a wheel rotation speed exceeds a predetermined parking lock prevention wheel rotation speed. The controller (CU, 10) is programmed to prevent the locking operation of the parking lock mechanisms (6) of the right and left wheels (3RR, 3RL) when a predetermined parking lock permitting condition based on wheel rotation speeds of the right wheel (3RR) and the left wheel (3RL) is not satisfied, thereby preventing a state in which one of the right and left wheels (3RR, 3RL) is prevented from rotating while the other is not prevented from rotating.Type: GrantFiled: March 8, 2010Date of Patent: June 2, 2015Assignee: NISSAN MOTOR CO., LTD.Inventor: Yutaro Kaneko

Patent number: 8973716Abstract: Brake mechanisms for a wheel of non-motorized wheeled vehicle such as, e.g., a shopping cart, are described. In various embodiments, the brake mechanism can provide a variable amount of braking force or torque between zero and an amount sufficient to lock the wheel. In some embodiments, the brake mechanism includes a brake plate that is movable toward and away from a surface of the wheel hub along a direction parallel to the rotation axis of the wheel. The brake plate is configured not to rotate when the wheel and hub are rotating. Frictional engagement between the brake plate and the surface of the wheel hub provides the braking force. The brake plate and/or the surface of the wheel hub can include engagement features such as, e.g., protrusions and slots. In some embodiments, the brake mechanism fits entirely within the wheel.Type: GrantFiled: October 25, 2010Date of Patent: March 10, 2015Assignee: Gatekeeper Systems, Inc.Inventors: John C. McKay, Stephen E. Hannah

Patent number: 8925706Abstract: A vehicle parking brake control has an extendable pin with three faces, and a roller on a lower surface. The faces correspond to engage, hold, and disengage of a parking brake. The control also has a lever rotatably connected to it, where the lever has a roller at a lower lever surface. The roller being capable of rotational contact with the pin faces. Further, the control has a base with an upper surface for the pin roller to move across. When the parking brake is engaged the lever roller is in contact with a first face, when the brake is on hold the lever roller is in contact with a second face, and when the brake is in the disengage position the lever roller is in contact with a third face of the extendable pin. Consequently, the rollers provide a reliable lifelong operation of the control over prior controls.Type: GrantFiled: September 23, 2013Date of Patent: January 6, 2015Assignee: Dana Automotive Systems Group, Inc.Inventors: Douglas R.

Patent number: 8899638Abstract: The invention relates to a locking system for a rotatable part, in particular in arrangements in which two parts which can be rotated in relation to each other, for example a die and a punch in a stamping apparatus, have to be aligned exactly in relation to each other. In order to provide a positionally accurate mechanical locking system with a simple design, the invention proposes that a gearwheel (3) having an end-side and/or axially effective toothing system (4) is connected to the rotatable part (2) fixedly in terms of rotation, and that at least one toothing segment (5a-5f) which can move to and fro in the direction of the axis of rotation and/or parallel to the axis of rotation of the gearwheel is arranged over the circumference of the gearwheel, wherein the teeth or gaps between the teeth of the toothing segment and gearwheel can be brought into engagement without play.Type: GrantFiled: June 25, 2009Date of Patent: December 2, 2014Assignee: Flamm GmbHInventor: Frieder Flamm
