Abstract
A vehicle-mounted apparatus includes: a motor unit configured to apply a rotational driving force to a wheel of a vehicle and including a drive motor and a speed reducer that reduces a speed of rotation of an output shaft of the drive motor; and a friction brake that reduces rotation of the wheel. The friction brake includes: at least one rotation disc provided so as to be rotatable integrally with the output shaft; a housing that is a non-rotatable member; at least one friction plate held by the housing so as to be movable relative to the housing in the axial direction such that rotation of the at least one friction plate relative to the housing about the axis is restricted; and a pressing device that presses the at least one friction plate against the at least one rotation disc.
Claims16
A vehicle-mounted apparatus, comprising:
- a motor unit comprising a drive motor and a speed reducer configured to reduce a speed of rotation of an output shaft of the drive motor, the motor unit being configured to apply a rotational driving force to a wheel of a vehicle;
- and
- a friction brake configured to reduce rotation of the wheel,
- wherein the friction brake comprises:
- at least one rotation disc provided so as to be rotatable integrally with the output shaft of the drive motor;
- a housing that is a non-rotatable member;
- at least one friction plate held by the housing so as to be movable relative to the housing in the axial direction such that rotation of the at least one friction plate relative to the housing about the axis is restricted;
- and
- a pressing device configured to press the at least one friction plate against the at least one rotation disc.
A friction brake configured to reduce rotation of a wheel that is driven by a motor unit comprising a drive motor and a speed reducer configured to reduce a speed of rotation of the drive motor, the friction brake comprising:
- at least one rotation disc provided so as to be rotatable integrally with an output shaft of one of the speed reducer and the drive motor;
- a housing that is a non-rotatable member;
- at least one friction plate held by the housing so as to be movable relative to the housing in the axial direction such that rotation of the at least one friction plate relative to the housing about the axis is restricted;
- and
- a pressing device configured to press the at least one friction plate against the at least one rotation disc,
- wherein the pressing device comprises:
- a pressing member held by the housing so as to be movable in the axial direction;
- and
- a drive source configured to apply a force in the axial direction to the pressing member.
A friction brake configured to reduce rotation of a wheel of a vehicle which is driven by a motor unit comprising a drive motor and a speed reducer configured to reduce a speed of rotation of an output shaft of the drive motor, the friction brake comprising:
- at least one rotation disc provided so as to be rotatable integrally with the output shaft of the drive motor;
- a housing that is a non-rotatable member;
- at least one friction plate held by the housing so as to be movable relative to the housing in the axial direction such that rotation of the at least one friction plate relative to the housing about the axis is restricted;
- and
- a pressing device configured to press the at least one friction plate against the at least one rotation disc.
