Title: Tire air pressure detector
Inventor: TOMINAGA MOTONORI
IPC: B60C23/06
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To detect a tire air pressure drop accurately even under an influence of a tread lift. SOLUTION: An air pressure drop rate is computed from a variation in a corrected wheel speed deviation value D'AVE per unit time, and from the air pressure drop rate, a warning prediction time when the wheel speed deviation value D'AVE will be across a warning threshold level is computed. When the warning prediction time is reached, a tire air pressure drop is detected irrespective of an actual wheel speed deviation value D'AVE. In the course of the drop in air pressure, even if a vehicle speed is increased and a tread lift influences the corrected wheel speed deviation value D'AVE to change to a side causing no tire air pressure drop, the tire air pressure drop can be detected accurately when it is the warning prediction time.

Title: Spring-applied parking brake assembly having manual quick release mechanism
Inventor: ZEMYAN JAMES M
IPC: F16D65/22
Filed: 2001-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a spring-applied parking brake assembly for a train brake system, for automatically applying a parking brake when there is no air supply. SOLUTION: The spring-applied parking brake assembly 60 includes a cylindrical easing 70, inside which a longitudinally movable piston assembly 72 is contained. The piston assembly is connected to the force distribution lever of the brake system to apply a force to the force distribution lever during longitudinal movement. At least one spring member 78 is provided in the cylindrical casing. Since the spring member applies a certain force to the piston assembly, when pneumatic pressure to the brake system is eliminated, the piston assembly automatically moves longitudinally whereby the piston assembly recedes inside the casing and the force distribution lever rotates in the direction to start applying the brake. Hence, the brake of the vehicle is automatically applied when the vehicle is removed from a train and an air supply part for the pneumatic brake system is separated.
