Filed:

Apr 29, 2008

Appl. No.:

12/111578

Inventors:

Andrew Joseph McDaniel - Chapel Hill NC, US

Assignee:

Honda Motor Co., Ltd. - Tokyo

International Classification:

F16D 67/06
F16D 37/02

US Classification:

192 12A, 192 215, 1882672

Abstract:

Magneto-rheological brake-clutch apparatuses and methods are provided. According to one aspect, a magneto-rheological brake-clutch can include a drive member and a driven member spaced from the drive member with a gap defined between the drive and driven members. A first quantity of MR fluid can be disposed in the gap. A brake assembly can define a chamber having a second quantity of MR fluid disposed therein and having a braking structure positioned in the chamber and connected to the driven member. A magnetic field generation assembly can be configured to selectively apply a magnetic field to the first quantity of MR fluid for controlling engagement of the driven member with the drive member. The assembly can be configured to selectively apply a magnetic field to the second quantity of MR fluid for controlling engagement of the braking structure with the brake assembly to brake the driven member. A magnet can be used and selectively positioned for applying a magnetic field to the first and second quantities of MR fluid.

Abstract:

Magneto-rheological clutch and wheel transmission apparatuses and methods are provided. According to one aspect, a magneto-rheological clutch system can include first and second drive members and first and second driven members. A first gap can be present between the first drive and first driven members. A second gap can be present between the second drive and second driven members. A drive wheel and a snow blower impeller can be connected to the first and second driven member, respectively. First and second MR fluids can be disposed in the first and second gaps, respectively. A first magnetic field can be applied to the first MR fluid for engaging the drive wheel. A second magnetic field can be applied to the second MR fluid for engaging the snow blower impeller. The provided apparatuses and methods can also be applied to mower blades and wheels.

Appl. No.:

11/868347

Inventors:

Andrew Joseph McDaniel - Chapel Hill NC, US
Christopher Wayne Vaughn - Mebane NC, US

Assignee:

Honda Motor Co., Ltd. - Tokyo

International Classification:

F16H 15/10

US Classification:

476 57, 384 43

Abstract:

Linearly adjustable torque transmission systems and methods for a power driven machine are provided. The system can include a first wheel adapted to be rotatably driven. The system can further include a second wheel positioned proximate the first wheel that can engage the first wheel such that rotational movement of the first wheel can impart rotational movement to the second wheel. The second wheel can be coupled to a shaft with bearings between the second wheel and the shaft such that the second wheel is movable along the shaft in a lateral direction while the second wheel is coupled to the shaft wherein rotational movement of the second wheel rotationally moves the shaft.

Christopher Wayne Vaughn - Mebane NC, US
Andrew Joseph McDaniel - Chapel Hill NC, US

International Classification:

B22F 3/14
F16D 9/00
F16H 35/10

US Classification:

419 53, 464 32, 74640

Abstract:

Apparatuses and methods are provided for transmitting torque in a way that can prolong the life of such apparatuses by using dissimilar materials for a body region and a torque transmitting region that absorbs the wear of the apparatuses, the apparatuses being constructed by methods of powder metallurgy. A torque transmitting apparatus can be provided and can include an annular body member composed of a first material and an outer ring member composed of a second powder metal material. The outer ring member can shrink about the annular body member during a sintering phase to form a single body in which the outer ring member can be fixedly attached to the annular body member.

International Classification:

A01B 79/00
A01B 33/10

US Classification:

172 1, 172243, 172 42

Abstract:

Apparatuses and methods are provided to facilitate the transport and storage of tilling machines and specifically mini-tillers. A wheel apparatus can attach to a tilling machine, such as by attachment to a drag bar, in a transport position or a storage position. In the transport position, the wheel apparatus can maintain tiller tines of the tilling machine above the ground surface with the weight of the tilling machine supported on the wheel apparatus, thereby allowing the tilling machine to be rolled for transport. In the storage position, the wheel apparatus can be attached to the drag bar, whereby both the tiller tines and the wheel apparatus rest on the ground surface to provide stability to the tilling machine. During operation the wheel apparatus can be removed from the tilling machine.
