A tube-pressed brake includes a tube for being injected with a pressure fluid to produce a pressure therein to permit transmission of a torque between two members arranged in a combination and rotating relative to each other. The tube has been applied with a coating.

Tube-pressed brake

A friction engaging device capable of obtaining a large transfer torque capacity with a compact and simple construction and smoothly connecting and disconnecting friction engaged members. A wet type multi-disc clutch has a clutch case, a hub and a main clutch. A variable length joint is provided between an inner cylindrical portion of the clutch case and a cylindrical portion of the hub. The variable length joint is constructed mainly of a first cam plate so held as to be slidable in the axial direction on the hub, a second cam plate so held as to be rotatable relatively to the clutch case, and a plurality of rollers interposed between the first and second cam plates. A tube type clutch for making the second cam plate and the clutch case frictionally engage with each other, is provided in a gap between the second cam plate and the inner cylindrical portion of the clutch case.

Friction engaging device

An elastic-tube-operated brake band is used by arranging it between an inner member and an outer member. The brake band includes a ring-shaped strap with a friction material fixedly secured on a circumferential surface thereof. The brake band is also with an elastic tube which is arranged on a side of an opposite circumferential surface of the ring-shaped strap. By a pressure produced by charging pressure fluid into the tube, the friction material is brought into engagement with a counterpart via the ring-shaped strap to transmit a torque between the inner member and the outer member. The ring-shaped strap is fixed at opposite ends thereof with play in a circumferential direction, respectively.

Elastic-tube-operated brake band

A tube-pressed brake band is arranged between inner and outer rings having a common center to stop rotation of one of the inner and outer rings as a counterpart by inflating a ring-shaped tube, which is inflatable in a radial direction of the brake band, into engagement with the counterpart. The tube-pressed brake band has a ring-shaped strap arranged between the counterpart and the tube and relative to an angular direction, is fixed at an end thereof on the other one of the inner and outer rings.
