Drive disks

Drive disks are configured to rotate a main wheel by applying a frictional force thereto. Each of the drive disks includes a base and a plurality of rollers. The base includes a first sheet metal member and a second sheet metal member. The first sheet metal member includes a first central part and a plurality of first arm parts. The second sheet metal member includes a second central part and a plurality of second arm parts. Each of the rollers has a first end and a second end in an axial direction thereof. Each of the first arm parts and each of the second arm parts support the first end of one of two rollers adjacent to each other and the second end of the other of the two rollers adjacent to each other.

A manufacturing apparatus for a drive disk includes: an upper member and a lower member each including a base and protrusions. Each protrusion is defined by a plurality of surfaces including a first side surface inclined with respect to opposed surfaces of the drive disk and a second side surface parallel to the opposed surfaces. The first side surface of the protrusion of the upper member and the first side surface of the protrusion of the lower member are parallel to each other and face away from each other. The second side surface of the protrusion of the upper member and the second side surface of the protrusion of the lower member face away from each other. The first side surface of the protrusion of the upper member and the first side surface of the protrusion of the lower member come into contact with each other to form the slot.

Manufacturing apparatus for drive disk

Provided is a steering mechanism () including a swing bar () which swings in response to input from a rider, a cam guide () slidable on a peripheral surface of a column section (), a ball joint () which slides the cam guide () in response to the swinging of the swing bar (), a cam follower () vertically provided on the peripheral surface of the column section () to rotate the column section () in response to the sliding of the cam guide (), and a coil spring () which returns the cam guide () to a predetermined rotation angle. The cam follower () comes in contact with a cam surface () of the cam guide () which has a recess surface shape, at two positions on the peripheral surface, in a state where the column section () is located at a predetermined position.

The steering angles of front wheelsand rear wheelsof a vehiclecan be respectively controlled by a front wheel steering angle control actuatorand a rear wheel steering angle control actuator. If a steering wheelis operated in a turning direction of the vehiclewhile the vehicleis traveling in a straight line, then a controllerchanges the steering angle of the front wheelsto approach to a steering angle specified on the basis of an operation amount after the steering wheelis operated, and also controls the front wheel steering angle control actuatorand the rear wheel steering angle control actuatorto change the steering angles of the rear wheelsto the opposite direction of the turning direction of the vehicleimmediately after the steering wheelis operated.

A joint mechanismhas a zigzag structureextending in a zigzag pattern between a first memberand a second member. A flexible lengthy memberfixed to the first memberextends from the first membertoward the second memberand is travelable with respect to the second member. A tension application unitthat applies a tension to the flexible lengthy memberis configured to be capable of changing a tension to apply.

Joint mechanism

A movement assistance device is provided with thigh frames, lower leg frames, and knee joint mechanisms which are disposed on the outer side and the inner side, respectively, of each knee of a person to be assisted. Each of the thigh frames has a first main frame, which extends in the longitudinal direction of a thigh from a base disposed on one side of the hip of the person to be assisted to the outer knee joint mechanism, a second main frame, which obliquely extends on the front side of the thigh from the base to the inner knee joint mechanism, and a body support member, which is extended between the two main frames on the rear surface side of the thigh.

Movement assistance device

A present invention provides a joint power control device. A joint interlock displacement part () of a power transmission movable mechanism (), which is comprising of a moving pulley () and the like, is connected to a joint mechanism () disposed between a first member () and a second member (). A flexible lengthy member (), which is one of two flexible lengthy members () extending from the power transmission movable mechanism (), is connected to a control mechanism () that controls the movement of the flexible lengthy member (). Further, an elastic structure () is engaged with the other flexible lengthy member ().

Joint mechanism control device

A joint power generating device () has a multilayer structure constituted by alternately stacking an elastic member (), which incorporates a hermetically sealed air chamber, and a partition plate () with high stiffness, an elastic structure (), which has a through hole () formed therein, and a flexible lengthy member () inserted in the through hole (). The joint power generating device () is configured to transmit a force between the lengthy member () and the elastic structure () such that the force for compressing the elastic structure () increases as the tension on the lengthy member () increases.

Elastic force generating device

In a mobile vehiclehaving a vehicle body, a front wheel, and a rear wheel, the steering control wheelcan be steered by a steering actuatorabout a steering axis Csf which is tilted backward. The steering actuatoris controlled by a control device. The height a, from a ground surface, of the intersection point Ef of the steering axis Csf of the steering control wheeland a virtual straight line connecting the ground contact point of the steering control wheeland the center of axle of the steering control wheelin a basic posture state of the mobile vehicleis set to satisfy a prescribed condition.
