Title: Innovations of Barry Lewis Ladd
Introduction
Barry Lewis Ladd is an accomplished inventor based in Zionsville, Indiana. He has made significant contributions to the field of automotive technology, holding a total of three patents. His work focuses on improving vehicle transmission systems, enhancing performance and efficiency.
Latest Patents
One of Ladd's latest patents is a method for controlling a transmission during acceleration from idle. This innovative method begins when the vehicle is stationary, the engine is at idle, and the transmission is in the first gear range. As the vehicle accelerates, the method monitors the rate of acceleration and compares it to a predetermined threshold. If the acceleration is below this threshold, the transmission allows one of the engaged clutches to slip, reducing the torque load on the engine. The method also includes monitoring the engine output speed and fully applying the clutch when the output speed exceeds a certain threshold.
Another notable patent by Ladd involves the connection between an engine output shaft and a transmission torque converter. This design features a flex plate that is secured for rotation with either the output shaft or the torque converter input shell. The flex plate includes a rim that is frictionally engaged with an annular wall, allowing for effective torque transmission. A clamp member surrounds the rim to establish sufficient frictional engagement to transmit torque effectively.
