Introduction

Kyoko Tanaka is a prominent inventor based in Namegata, Japan. She has made significant contributions to the field of construction machinery, particularly through her innovative designs and patents. With a total of 3 patents, her work has had a notable impact on the industry.

Latest Patents

One of her latest patents is a travel drive device for dump trucks. This invention features a wheel mounting cylinder that is rotatably provided on the outer peripheral side of an axle housing through wheel support bearings. A wet brake is integrated between the axle housing and the wheel mounting cylinder to apply a braking force to the rotation of the wheel mounting cylinder. Additionally, a seal mechanism is included to maintain the cooling liquid of the wet brake in a sealed state, preventing contamination with lubricant oil in the wheel mounting cylinder. Furthermore, a foreign-object trapping portion is designed to capture any foreign objects that may flow from the seal mechanism toward the wheel support bearing.

Another patent for the travel drive device for dump trucks includes an axle housing and a rotational shaft that extends axially within the spindle of the axle housing. The wheel mounting cylinder is mounted on the outer peripheral side of the spindle through wheel support bearings, and a planetary gear reduction mechanism is employed to decelerate the rotation of the rotational shaft, which is transmitted to the wheel mounting cylinder. A carrier, which is part of the planetary gear reduction mechanism, is mounted in a non-rotating state on the open end side of the spindle. A cylindrical coupling member is also provided between the spindle and the carrier, featuring splined couplings on both ends.
