  • Patent number: 9845132
    Abstract: A rear wheel suspension system pivotably attached to a bicycle. The suspension system has an upper link attached to a main frame at a first pivot point, and a rear stay member attached to the upper link at a second pivot point. A lower link is attached to the main frame at a third pivot point, and is pivotably attached to the rear stay member at a fourth pivot point. A shock absorber is pivotably connected to the upper link and to the main frame. An instantaneous center of rotation (ICR) is defined where an upper axis extending through the first and second pivots intersects a lower axis extending through the third and fourth pivots. The ICR displaces along a trajectory from behind the bottom bracket, through an inflection point at which the upper axis and the lower axis are parallel, to in front of the bottom bracket, as the shock absorber compresses.

  • Patent number: 9770955
    Abstract: A lock for securing a trailer hitch includes a latching member, a position-limiting assembly, and a housing. The position-limiting assembly includes first and second position-limiting members, a magnetic member, and a securing pin. The first position-limiting member is configured for detachable engagement with the latching member. The second position-limiting member is mounted in the housing, receives the magnetic member, and is slidably connected to the first position-limiting member via the securing pin in order to be moved to an engaged position and a disengaged position. When at the engaged position, the second position-limiting member is mounted to the latching member due to the magnetic member and thereby fixes the first position-limiting member in position. When at the disengaged position, the second position-limiting member is separate from an end portion of the latching member to allow detachment of the first position-limiting member from the latching member.

  • Patent number: 9744988
    Abstract: An electric power steering apparatus is configured to provide steering assistance as rotary torque of a driving toothed-pulley fixedly fitted to a rotary shaft of an electric motor is transmitted through a toothed belt to a driven toothed-pulley that rotates together with a ball screw nut in an integrated manner. The electric power steering apparatus is configured such that the amount of axial travel of a rack shaft is limited when a rack end and a housing come into contact with each other in the axial direction. The electric power steering apparatus includes a tilt allowing portion configured to cause the ball screw nut to tilt relative to a ball screw shaft such that the distance between the center of rotation of the driven toothed-pulley and that of the driving toothed-pulley increases when the rack end and the housing come into contact with each other in the axial direction.
