Abstract
A toroidal continuously variable transmission including at least one containment body covering a target disc that is at least one of an input disc and an output disc. The containment body includes a ring that covers an outer peripheral surface of the target disc so as to be spaced apart from the outer peripheral surface of the target disc in a radial direction. A maximum dimension of the ring in an axial direction is larger than a maximum dimension of the outer peripheral surface of the target disc in the axial direction.
Claims3
A toroidal continuously variable transmission comprising:
- an input disc including a speed change surface;
- an output disc including a speed change surface;
- a power roller located between the speed change surface of the input disc and the speed change surface of the output disc so as to be tiltable;
- at least one containment body covering a target disc that is at least one of the input disc and the output disc;
- and
- a housing that houses the input disc, the output disc, the power roller, and the containment body, wherein:
- the containment body includes a ring that covers an outer peripheral surface of the target disc so as to be spaced apart from the outer peripheral surface of the target disc in a radial direction;
- a maximum dimension of the ring in an axial direction is larger than a maximum dimension of the outer peripheral surface of the target disc in the axial direction;
- the power roller is located in a predetermined phase region around the axial direction;
- the ring includes
- a first section corresponding to the phase region of the power roller around the axial direction;
- and
- a second section that is a phase region around the axial direction other than the first section, the second section corresponding to no power roller;
- the containment body further includes a guard located at one side of the ring which is close to the power roller in the axial direction;
- and
- the guard is located at the second section of the ring,
- wherein:
- the at least one containment body comprises
- a first containment body covering the input disc and
- a second containment body covering the output disc;
- and
- the first containment body and the second containment body are connected to each other by a coupling body.

- an input disc including a speed change surface;
- an output disc including a speed change surface;
- a power roller located between the speed change surface of the input disc and the speed change surface of the output disc so as to be tiltable;
- at least one containment body covering a target disc that is at least one of the input disc and the output disc;
- a housing that houses the input disc, the output disc, the power roller, and the containment body;
- and
- a supporting body connected to the housing, wherein:
- the containment body includes a ring that covers an outer peripheral surface of the target disc so as to be spaced apart from the outer peripheral surface of the target disc in a radial direction;
- the supporting body includes an actuator body supporting an actuator that tilts the power roller;
- and
- the containment body is connected to the housing through the actuator body.

- an input disc including a speed change surface;
- an output disc including a speed change surface;
- a power roller located between the speed change surface of the input disc and the speed change surface of the output disc so as to be tiltable;
- at least one containment body covering a target disc that is at least one of the input disc and the output disc;
- a housing that houses the input disc, the output disc, the power roller, and the containment body;
- and
- a joint that connects the containment body to the housing, wherein:
- the containment body includes a ring that covers an outer peripheral surface of the target disc so as to be spaced apart from the outer peripheral surface of the target disc in a radial direction;
- and
- the joint includes an absorber that allows the containment body to be displaced.
