  • Device for measuring bending angle of constant velocity joint of drive shaft
    Patent number: 8981768
    Abstract: Provided is a device for measuring a bending angle of a constant velocity joint of a drive shaft, the device including an outer race provided at a drive shaft and having an opening part formed at one end thereof, a permanent magnet mounted in the opening part of the outer race, and a sensor provided on an outer peripheral surface of the drive shaft and interlocking with the permanent magnet to measure a bending angle between the drive shaft and the outer race. Therefore, a size and a direction of the bending angle between the drive shaft and the outer race may be measured, thereby making it possible to improve marketability and stability of a vehicle.

  • Width variable structure of moving and transport means using mecanum wheels
    Patent number: 8607902
    Abstract: A width variable structure using mecanum wheels is provided, which includes a plurality of mecanum wheels, a plurality of links connecting the mecanum wheels, and motors mounted on the mecanum wheels to transfer driving forces to the links, respectively. Since the width of the structure in the horizontal and vertical directions can be adjusted using the driving forces of the mecanum wheels, components such as actuators are omitted in the overall assembly.
