A brake operating device in which an operation of a brake pedal can be detected easily by a simple structure is provided. The brake operating devicecomprises: a pusherconnected to a brake pedal; a hydraulic systemin which fluid is held between the pusherand a pushing elementto transmit a thrust force of the pusherto the pushing element; a first elastic mechanismthat establishes an elastic force to isolate the pusheraway from the pushing element; a cylinderholding the pusherwhile restricting a withdrawal limit of the pusherin a direction away from the pushing element; and a second elastic mechanismthat is arranged at a position to push the cylinder, and that establishes an elastic force against the elastic force in the direction to isolate the pusheraway from the pushing element

Brake operating device

A pedal stepping force detector includes a rod, a case having a bottomed-cylindrical shape and extending along a longitudinal direction of the rod, a strain body housed in a bottom portion of the case, an operating body that is housed in the case so that the operating body is in contact with the strain body, and an elastic member that is compressed in association with an operation of the rod and thus causes biasing force to act on the operating body

Pedal stepping force detector

A load detection apparatus includes an input member for receiving input of a load, a tubular body having a strain element configured to generate a strain due to the load inputted to the input member, a strain detection element fixed to a face of the strain element opposite its face that comes into contact with the input member, the strain detection element being configured to detect the strain generated in the strain element, a circuit board mounted to oppose the strain detection element in a tube axis direction of the tubular body, the circuit board being configured to input detection information of the strain detection element, and a connection member having a first connection portion to be electrically connected to the strain detection element and a second connection portion to be electrically connected to the circuit board.

Load detection apparatus having a strain detection element attached to a connection portion opposite the circuit board

A load detection apparatus includes a load input portion having a input surface, and an output surface; a flexure element including on annular portion including a contacting portion configured to make contact with at least a part of the output surface, and a support portion; a set of sensors disposed on a reverse surface opposite to a surface provided with the contacting portion in the annular portion, each of the set of sensors being configured to detect distortion corresponding to an input load; a set of calculation portions configured to calculate a set of magnitudes of the load by use of respective detection results obtained by the set of sensors; and an abnormality determination portion configured to determine whether the set of sensors and the set of calculation portions have no abnormality, by comparing the set of magnitudes of the load with each other.

Load detection apparatus

The electric braking device is provided with: a pressing member, which has a thread portion with either an internal thread or an external thread and which applies a pressing force on a frictional member; a shaft member, which is rotated by an electric motor and is threadedly engaged with the thread portion; a first spherical surface member, which is separated from the shaft member, being capable of rotating relative to the shaft member around the axis of rotation of the shaft member, and the end surface of which is a spherical surface; and a second spherical surface member, which is in sliding contact with the spherical surface of the first spherical surface member, receives the reaction force of the pressing force, and is restrained from rotating with respect to the axis of rotation of the shaft member.

Electric vehicle braking device

A highly sensitive load detection device includes a tubular peripheral wall portion; a disk-shaped disk portion that has a through hole formed coaxially with the peripheral wall portion and that is supported on an inner surface of the peripheral wall portion with a gap between the disk portion and a placement surface on which the peripheral wall portion is placed; a load input portion that is formed in a spherical shape having a diameter larger than an inside diameter of the through hole on at least a side thereof facing the through hole, that is placed on the through hole, and to which a load of an object to be detected is input; and sensors that are provided on the disk portion so as to be point-symmetric about the through hole, and that detect a strain corresponding to the load input to the load input portion.
