The present invention provides one or more carrier devices capable of varying contact damping with pressured displacement. The device is configured to be installed on mechanical force-receiving structures that have rolling wheels, rolling balls or slidably displaceable terminal block structure, carrying devices and transportation devices for humans or objects. When receiving pressure smaller than a set value, the device provides low contact damping and is thus easy to move. On the other hand, when receiving pressure greater than the set value, it provides high contact damping so as to prevent slip and thereby ensure safe placement.

In addition, when receiving pressure smaller than the set value, the device has its pre-stressed structure generate modulation to displacement corresponding to the size of the pressure it receives for the purpose of shock absorbency.

An outer ring of an inner joint of the constant speed transmission shaft is provided with a vehicle speed sensor rotating synchronously with the inner joint, and the drive axle is fixedly equipped with a signal collecting device opposite to the vehicle speed sensor and configured to monitor a rotation speed signal of the vehicle speed sensor. The inner joint of the constant speed transmission shaft transmits torque during the running of a vehicle, and through monitoring a rotation speed of the inner joint, the rotation data of rear wheels can be obtained. By mounting the vehicle speed sensor on the inner joint and fixing the signal collecting device on the drive axle for monitoring the rotation speed signal of the vehicle speed sensor, the signal reading is stable, which facilitates the maintenance, reduces the cost, and can satisfy the environmental requirements.

The present disclosure generally relates to an omni-direction wheel system and methods for controlling the omni-direction wheel system. The omni-direction wheel system includes a plurality of suspension systems that operate independently of one another. Each suspension system may include an electromagnetic steering hub configured to rotate a wheel 360 degrees about a vertical axis based on a polarity of an electromagnetic signal applied to the electromagnetic steering hub. The suspension system may further include an in-wheel motor configured to rotate with the wheel and drive the wheel about a horizontal axis.

A spoke attachment assembly configured to couple a rim to the spokes of a spoked bicycle wheel. The spoke attachment assembly comprises a nipple having an enlarged head and a stem provided with a coupling portion for coupling with a spoke, at least one shaped washer associated with the nipple and configured to abut on one side with the enlarged head of the nipple and, on the opposite side, with the rim and holding means configured to hold said at least one shaped washer associated with the nipple. The invention also relates to a spoked bicycle wheel and to a process for manufacturing such a wheel.

A bicycle ratchet hub assembly includes a ratchet unit and a damping unit located between the hub and the socket unit. The ratchet unit has a ratchet ring in the hub. Multiple recesses are defined in the seat and each have a pawl pivotably located therein. The damping unit is located between the axle and the hub, and includes a damping member which has slots defined therein. A pin protrudes from each of the pawls and movably extends through the corresponding slot. By the damping feature of the damping member, the damping member delays a period of time to begin to rotate, and the pins of the pawls move in the slots and the pawls are pivoted outward to be engaged with the ratchet teeth of the ratchet unit without using any resilient part. A magnetic driving device located in the hub to attract the pawls to be pivoted outward.

A rolling bearing unit includes: an inner ring member having a recess on a first side in an axial direction along a rotation axis, which is recessed toward a second side in the axial direction; an outer ring member on an outer peripheral side of the inner ring member; a rolling body between the inner ring member and the outer ring member; a non-contact transmitter using electric field coupling capable of transmitting at least one of an electric power or a signal and including a stationary-side transmission part including a stationary-side electrode and a rotary-side transmission part including a rotary-side electrode facing the stationary-side electrode; and a covering member supported by the first side of the outer ring member in the axial direction, covering the first side of the inner ring member in the axial direction, and fixing the stationary-side transmission part to the first side in the axial direction.

Provided is a magnetic levitation power system. The magnetic levitation power system includes: a magnetic power system disposed on a wheel hub and a driver shaft, where the magnetic power system generates a power capable of enabling a movement of the wheel hub through an interaction of magnetic fields between the wheel hub and the driver shaft; a first magnetic levitation system disposed on the wheel hub and the driver shaft, where the first magnetic levitation system is capable of enabling the wheel hub and the driver shaft to be in a levitation state within a circumferential extent of 360 degrees with the wheel hub being opposite to the driver shaft through the interaction of the magnetic fields between the wheel hub and the driver shaft; and a second magnetic levitation system disposed on the wheel hub and the driver shaft, where the second magnetic levitation system is capable of enabling the wheel hub and the driver shaft to be in a levitation state in a direction of a central axis of the wheel hub through the interaction of the magnetic fields between the wheel hub and the driver shaft. The present invention solves the problems of high hardware costs, low energy utilization rate, environmentally harmful characteristics, etc. of the existing automobile power system.
