  • Patent number: 11072237
    Abstract: A UTV portal axle system is disclosed, including a spindle with a housing for housing input and output drive gears coupled by one or more idler gears. The output drive gear is disposed lower than the input drive gear to provide additional ground clearance to the UTV. The king pin axis angle is substantially the same as that of a stock UTV, while maintaining a scrub radius of substantially one inch or less. This is accomplished by the lower control arm ball joint being located within a recess of the output drive gear. This allows the UTV to be properly controlled when driven at high speeds over rough or uneven terrain. The gears may be interchangeable to allow the gear ratio to be adjusted to be more suitable for use at various driving speeds. A method of changing the gear ratio is also disclosed.

  • Patent number: 11014491
    Abstract: A bracket is rotatable between a neutral position and a direction indication position in response to an operation by a user. A ratchet is slidable between a position where the ratchet enters a rotating trajectory of a cancel cam mounted on a steering shaft of a vehicle and a position where the ratchet retracts from the rotating trajectory interlocking with rotation of the bracket. A first regulating member defines a guide groove that guides sliding of the ratchet that regulates displacement of the ratchet in a direction along the rotating trajectory. A second regulating member is provided on the ratchet and regulates displacement of the ratchet in a direction intersecting both a sliding direction of the ratchet and the direction along the rotating trajectory. A guide groove includes an open end which is opened toward the rotating trajectory.

  • Patent number: 10994707
    Abstract: A vehicle pedal sensor assembly for use in a vehicle brake pedal including a base and a pedal arm pivotally mounted to the pedal base. A sensor housing includes a non-contacting pedal position sensor and a contacting pedal force sensor. The sensor housing is mounted to the base of the vehicle brake pedal. A magnet is mounted to the pedal arm. The pedal position sensor senses a change in the magnitude and/or direction of the magnetic field generated by the magnet in response to a change in the position of the pedal arm for determining the position of the pedal arm. A pedal force application member exerts a force against the pedal force sensor in response to the change in the position of the pedal arm for determining the position of the pedal arm.
