Filed:

Aug 15, 2001

Appl. No.:

09/930623

Inventors:

Hans Hauser - Strongsville OH

Assignee:

MTD Products Inc. - Valley City OH

International Classification:

B60K 1730

US Classification:

180 63, 180 648, 180308

Abstract:

A Zero Turn Radius vehicle is provided that utilizes a drive system including a single hydraulic variable displacement pump and dual variable displacement hydraulic motors connected respectively one to each of two ground engaging wheels for use in steering and propelling the vehicle. The configuration of the drive system allows for proper ZTR steering of the in the forward and reverse directions.

Appl. No.:

10/245158

Inventors:

Hans Hauser - Strongsville OH, US

Assignee:

MTD Products Inc - Valley City OH

International Classification:

B62D007/00

US Classification:

180 634, 180 648

Abstract:

A ZTR vehicle includes true or proper ZTR steering in the forward and reverse directions. The vehicle has independently driven locomotive drives that drive the wheels to provide mobility and steering to the vehicle. A steering wheel is included that pivots one of two steering input members that rotate to independently shift the drive units. A speed and direction pedal is also included, which is communicated to provide direction and magnitude input to the drive units. The steering input and speed and direction inputs coordinate propelling the vehicle such the vehicle turns in the same direction when traveling forward as well as in reverse.

International Classification:

B62D 3/14

US Classification:

180 624, 180 62, 180 648

Abstract:

In a broad respect, vehicles that are capable of making a low- to zero-radius turn using the independent rotation of drive wheels and by turning the non-driving steerable structure or structures (such as wheels) with a steering input device (in some embodiments, the driving wheels also may be capable of being turned). This may be accomplished using a steering system, a speed control system and an integration device (together, a control system) that are configured to work together to provide correct steering in forward and reverse, and, in some embodiments, to reduce the speed of the outboard drive wheel of the vehicle when it enters an extreme turn under constant speed input. Different systems configured for use in such vehicles are included.

Filed:

Oct 3, 1994

Appl. No.:

8/322291

Inventors:

Hans Hauser - Strongsville OH

Assignee:

MTD Products Inc - Cleveland OH

International Classification:

D06F 3730
F16H 1904
F16D 310

US Classification:

68 237

Abstract:

A transmission for a washing machine which uses an off center gear in combination with a rack and pinion agitation mechanism, a brake clutch, and a drive clutch to provide the agitation and the high speed spin of the washing machine. A lost motion interconnection between the machine's motor and the rack and pinion agitation mechanism allows a measure of relative rotation for actuation of the clutches without movement of the agitator.
