摘要： A computerized brake control system which calculates desired brake pressure from commanded brake signal, vehicle weight, vehicle speed and dynamic braking, compares the desired brake pressure with the actual brake, and controls the fluid brake system to cause the actual brake pressure to be substantially equal to the desired brake pressure. For snow brake mode the computer sets a fixed value of desired brake pressure which is used for controlling the fluid brake system. After a fixed number of stops, the brake mode is temporarily disabled.

摘要： A composition brake shoe is used in a railway freight vehicle for reconditioning a wheel surface of a railway freight vehicle. Such brake shoe includes a brake surface having a predetermined configuration and a predetermined surface area. The composition brake shoe consists of a first friction composition material extending over the surface area of such composition brake shoe. A second friction type composition material is formed as a discrete insert, having a predetermined shape, and is molded into the first friction composition material. Such second friction composition material initially is completely embedded within the first friction composition material. One surface of the insert is disposed facing the predetermined surface area of the brake surface of the composition brake shoe. Such one surface of the insert being incrementally exposed as the first friction composition material is eroded away due to frictional engagement with the wheel tread surface during normal braking operations. The second friction composition material exhibits greater abrasive properties than the first friction composition material and consists essentially of a ceramic grinding material. Such first friction composition material extends entirely over the predetermined surface area of the brake surface of the composition brake shoe when the discrete insert has been worn away due to frictional engagement with the wheel tread surface during normal braking operations.

摘要： The present invention provides a friction management brake shoe adapted to engage the tread and the flange of a wheel of a railway vehicle via which the railway vehicle is guidably supported on a railed track. The friction management brake shoe comprises a brake lining affixed which has a braking surface engageable with the wheel tread of a wheel of a railway vehicle. The brake lining includes a first friction composition material formed with at least one of a solid high positive friction modifier and a solid very high positive friction modifier which establish a required friction level between the wheel tread and the railed track.

摘要： A brake shoe locking key is provided with a retention tab that is saw-tooth shaped and extends across the entire width of the key shank. The retention tab is upraised from the shank more than the correspondingly-shaped serrations typically formed on the bottom of the key and is thus more effective in engaging the brake head as an initial detent to prevent the key from backing out of the keyhole in the brake head when a loose fitting key fails to retain its locking position. In addition, the retention tab is adapted to engage the keybridge at the orifice through which the key passes in order to provide a further detent to prevent a loose key from backing completely out of its locking connection between the brake head and brake shoe, in the event the first detent fails to engage.

摘要： The invention is directed to an insert for a backing plate assembly for a composition friction brake shoe. The insert is particularly useful in the formation of a universal brake shoe for use with a trolley car braking system. The insert includes a central member having a first and second set of attachment posts extending from the respective ends thereof. These first and second sets of attachment posts are adapted for securing a first and second backing plate strap, respectively, thereto. A key bridge extends through a back portion of the central member and is configured for attachment to a brake shoe. A flange guide support extends from a side portion of the insert and includes legs defining a channel that runs parallel to the insert. The flange guide support is adapted for contacting a wheel flange to align a brake shoe with the wheel during braking of the vehicle.
