Claims17
A braking system for a vehicle truck, comprising:
- a dead vertical lever comprising a protrusion extending toward a live vertical lever and a slack adjuster of the braking system, wherein a protrusion opening is positioned on the protrusion, wherein the slack adjuster is coupled to the dead vertical lever via the protrusion opening, wherein the dead vertical lever is adapted to apply a first brake shoe force on a first wheel of the vehicle truck, wherein the live vertical lever is adapted to apply a second brake shoe force on a second wheel of the vehicle truck, wherein the dead vertical lever and the live vertical lever are interconnected with one another via the slack adjuster such that the first brake shoe force is applied on the first wheel of the vehicle truck when the second brake shoe force is applied on the second wheel of the vehicle truck via the live vertical lever, and wherein, due to the slack adjuster being coupled to the dead vertical lever at the protrusion opening, the first brake shoe force applied to the first wheel of the vehicle truck is less than the second brake shoe force applied to the second wheel of the vehicle.
A rail vehicle truck, comprising:
- a brake rigging arrangement for an unpowered axle of the rail vehicle truck, the brake rigging arrangement including:
- a dead vertical lever, a slack adjuster, and a live vertical lever, wherein the slack adjuster is coupled to a protrusion opening arranged on a protrusion of the dead vertical lever extending toward the live vertical lever and the slack adjuster, wherein the dead vertical lever is adapted to apply a first brake shoe force on a first wheel of the vehicle truck, wherein the live vertical lever is adapted to apply a second brake shoe force on a second wheel of the vehicle truck, wherein the dead vertical lever and the live vertical lever are interconnected with one another via the slack adjuster such that the first brake shoe force is applied on the first wheel of the vehicle truck when the second brake shoe force is applied on the second wheel of the vehicle truck via the live vertical lever, and wherein, due to the slack adjuster being coupled to the dead vertical lever at the protrusion opening, the first brake shoe force applied to the first wheel of the vehicle truck is less than the second brake shoe force applied to the second wheel of the vehicle.
A brake rigging system, comprising:
- a first axle comprising a first brake rigging arrangement, wherein the first brake rigging arrangement includes a first slack adjuster coupled to a first live vertical lever, wherein the first live vertical lever is adapted to apply a first brake shoe force on a first wheel of the first axle;
- a second axle comprising a second brake rigging arrangement;
- and
- a third axle comprising a third brake rigging arrangement, wherein the second brake rigging arrangement and the third brake rigging arrangement comprise a second slack adjuster coupled to a first dead vertical lever and a second live vertical lever, wherein the second slack adjuster is coupled to a protrusion opening arranged on a protrusion of the dead vertical lever extending toward the second live vertical lever and the second slack adjuster, wherein the second live vertical lever is adapted to apply a second brake shoe force on a second wheel of the second axle, wherein the dead vertical lever is adapted to apply a third brake shoe force on a third wheel of the third axle, wherein the dead vertical lever and the second live vertical lever are interconnected with one another via the second slack adjuster such that the third brake force is applied on the third wheel of the third axle when the second brake force is applied on the second wheel of the second axle via the second live vertical lever, and wherein, due to the second slack adjuster being coupled to the dead vertical lever at the protrusion opening, the third brake shoe force applied to the third wheel of the third axle is less than the second brake shoe force applied to the second wheel of the second axle.
