Latest Patents

One of Kitamura's latest patents is a friction element for a damper disc that includes a friction adjusting element. This invention features a damper disc assembly with multiple embodiments. In one embodiment, spring seats are arranged at opposite ends of coil springs located between a power input rotary member and a power output rotary member. Each spring seat has a contacting surface with mutually perpendicular slanting portions. Another embodiment introduces a modified spring seat that determines the phase or orientation of the power input rotary member concerning the power output rotary member. Additionally, a friction element made of resin includes a friction adjusting element that modifies the friction coefficient. In a fourth embodiment, a coating is applied to the friction surface to alter the friction coefficient.

Another significant patent is the damper disc assembly featuring non-rotatable spring seats. This design utilizes a pair of spring seats at opposite ends of a small coil spring situated between a power input rotary member and a power output rotary member. Each spring seat includes a receiving side surface for the spring and a contacting surface formed with four slanting surfaces that converge toward a central portion. The intersections of these slanting surfaces create two intersecting V-shaped grooves, which facilitate engagement between the rotary members and the grooves, thereby restricting the movement of the spring seats.
