A braking robot for a braking test of a vehicle is provided. The braking robot includes: a plurality of motors, having same individual output powers, combined with a robot body installed in the vehicle; a motion shaft combined with a pedal presser for applying pedal effort to a brake pedal of the vehicle; a driving force converter which converts rotational forces of the motors, corresponding to the individual output powers of the motors, into a translational force and thus transmits the translational force to the motion shaft; a load sensor, installed on the motion shaft, for detecting the pedal effort applied to the brake pedal by the motion shaft; and a controller for controlling operations of the motors by referring to (1) a scenario for the braking test and (2) information on the pedal effort detected from the load sensor.

A yoke member includes a primary yoke and a secondary yoke which are opposed to each other. The primary yoke is configured such that a maximum width of a widest portion of each of a plurality of primary teeth of the primary yoke is smaller than a minimum width of a narrowest portion of a primary ring plate of the primary yoke. The secondary yoke is configured such that a maximum width of a widest portion of each of a plurality of secondary teeth of the secondary yoke is smaller than a minimum width of a narrowest portion of a secondary ring plate of the secondary yoke.

Embodiments are directed to a drive shaft apparatus comprising a first rotary member and a second rotary member arranged coaxially with said first rotary member. The rotary members are fixedly connected at a first end so that they rotate together. Each rotary member has a set of elements spaced apart around its circumference at a second end. The elements on the first rotary member are spaced apart from the elements on the second rotary member at rest. The first rotary member undergoes torsion when a load is applied during rotation, which causes the first rotary member elements to move closer to the second rotary member elements. The first elements engage the second elements when a torque load less than a yield torque is applied to the first rotary member, which transfers at least a portion of the torque load to the second rotary member.

A measurement apparatus measures an electronic device that vibrates a touch surface to present a tactile sensation. The measurement apparatus includes a vibration detector that detects vibration of a touch surface, the vibration being produced in response to pressure applied to the touch surface, and a pressure detector that detects the pressure applied to the touch surface.

A multi-axis force and torque sensor and a robot are provided. The sensor includes a first supporting element, a second supporting element, a deformable component connected between the first supporting element and the second supporting element, and multiple signal pairs. The deformable component is configured to deflect in response to applied external force and torque in multiple directions. Each of the multiple signal pairs includes a magnet and a hall effect detector. The magnet is mounted on one of the first supporting element and the second supporting element, and the hall effect detector is mounted on the other. The hall effect detector is located corresponding to the respective magnet. One or more magnetization directions of the magnets of the signal pairs are different such that the signal pairs are capable of measuring force and torque applied on the first supporting element and the second supporting element in different directions.

A flexplate stress measurement system includes a flexplate being positioned between at least two components of a drive train of a vehicle. The flexplate is enclosed within the drive train and under operating conditions, is exposed to stress. At least one magnetic field sensing coil sensor is adapted and configured for measuring the stress acting on the flexplate under operating conditions within the drive train. The magnetic field sensing coil sensor being located on or in close proximity to the flexplate.

An electric bicycle having an electric motor mounted to a frame of the bicycle and which includes a motor output shaft defining an output end engaging a drive chain of the bicycles drive train to transmit the drive of the electric motor thereto. A torque sensor includes a base mounted in fixed relation to the frame and/or the electric motor. The torque sensor has a flexible arm extending from the base and a sensing member mounted to an extremity of the flexible arm that is displaceable relative to the base. The sensing member engages the drive chain along a segment thereof and is displaceable thereby. The segment of the drive chain extends from the output end of the motor output shaft to the pedal crank of the drive train.

A torque detection device includes an inner ring, a middle ring, an outer ring, a first beam, a second beam, a magnetic target, and a magnetic sensor. The first beam is composed of an elastic member extending in a radial direction so as to couple the inner ring and the middle ring together. The second beam is composed of an elastic member extending in a radial direction so as to couple the middle ring to the outer ring together. The magnetic target is fixed to the inner ring and the magnetic sensor is fixed to the middle ring such that the magnetic target and the magnetic sensor face each other. Torque acting on the inner ring or the outer ring is calculated according to how an amount of magnetism sensed by the magnetic sensor changes.

A method and a device (1) are provided for determining a torque of a transmission, in particular of an actuating drive (14), in which an elastically deformable bending element (4) that deforms as a function of the torque is arranged in a transmission path of the torque, and a sensor unit (8) with which deformation of the bending element can be detected forms a structural unit which can be mounted as a whole.
