Shackles are steel connectors made from a body and a pin.A shackle, also known as a gyve, is a U-shaped piece of metal secured with a clevis pin or bolt across the opening, or a hinged metal loop secured with a quick-release locking pin mechanism. The term also applies to handcuffs and other similarly conceived restraint devices that function in a similar manner.Shackles are the primary connecting link in all manner of rigging systems, from boats and ships to industrial crane rigging, as they allow different rigging subsets to be connected or disconnected quickly. A shackle is also the similarly shaped piece of metal used with a locking mechanism in padlocks.Types:Bow ShackleWith a larger "O" shape to the loop, this shackle can take loads from many directions without developing as much side load. However, the larger shape to the loop does reduce its overall strength. Also referred to as an anchor shackle.D-ShacklesAlso known as a chain shackle, D-shackles are narrow shackles shaped like a loop of chain, usually with a pin or threaded pin closure. D-shackles are very common and most other shackle types are a variation of the D-shackle. The small loop can take high loads primarily in line. Side and racking loads may twist or bend a D-shackle.Pin ShacklesA pin shackle is closed with an anchor bolt and cotter pin, in a manner similar to a clevis. It is for this reason they are often referred to, in industrial jargon, as clevises. Pin shackles can be inconvenient to work with, at times, as the bolt will need to be secured to the shackle body to avoid its loss, usually with a split pin or seizing wire. A more secure version used in crane rigging features the combination of a securingnut (hardware) located alongside the cotter pin. Pin shackles are practical in many rigging applications where the anchor bolt is expected to experience some rotation.Snap ShacklesAs the name implies, a snap shackle is a fast action fastener which can be implemented single handedly. It uses a spring activated locking mechanism to close a hinged shackle, and can be unfastened under load. This is a potential safety hazard, but can also be extremely useful at times. The snap shackle is not as secure as any other form of shackle, but can come in handy for temporary uses or in situations which must be moved or replaced often, such as a sailor's harness tether or to attach spinnaker sheets. Note: When this type of shackle is used to release a significant load, it will work rather poorly (hard to release) and is likely to have the pin assembly or the split ring fail.Twist ShacklesA twist shackle is usually somewhat longer than the average, and features a 90° twist so the top of the loop is perpendicular to the pin. One of the uses for this shackle include attaching the jib halyard block to themast, or the jib halyard to the sail, to reduce twist on the luff and allow the sail to set better.
we can put more load on the vehicle which is fitted with Bogie suspension compare toother suspension systems.
The venerable leaf spring, which some manufacturers still use in rear suspensions today, was invented by Obadiah Elliot of London in 1804. He simply piled one steel plate on top of another, pinned them together and shackled each end to a carriage.When_were_leaf_springs_invented
Tweezers are generally a welded two piece leaf spring apparatus designed to pull fine hairs from the face. Another use is to pick up very tiny objects. Tongs are shaped like tweezers but are much larger and have a coil spring at the junction of the two arms. Tongs are designed for remote handling of objects, generally food.

I believe its called a rear leaf shackle.
The bushings are pressed into the eye of the leaf spring on each end. The leaf spring should be removed and the old bushing pressed out on a shop press then press a new bushing pressed back in. In the old days I used to burn the old rubber out of the bushing then chisel out what is left.
if the axle is on top of the spring: get a pair of longer front spring shackle if the spring is under the axle: Get a pair of spring blocks.
The longevity of any leaf spring shackle and hanger depends on a few factors. For example, the age of the vehicle, frequency of the usage of the vehicle, the condition of the road and the weather where the vehicle operates etc. Naturally, in an older and heavily driven vehicle in a rough weather condition, the hanger and shackle might not last long. Whereas, in a well-maintained automobile, the springs can last more than 1,00,000 miles. An average lifespan of a set of leaf springs is around 2,00,000 miles.
I lift them on the frame rail next to the leaf spring shackle.
The front end is bracketed to prevent shifting of the axle. The rear is shackled, so that as pressure is exerted and removed, and the spring exspands and retracts, it will have room to move.
A set of leaf spring that is so mounted that it is at right angles to the length of the Vehicle is known as the transverse leaf spring.
the eye of a leaf spring, assuming u mean the eye at end of spring, is used to bolt the spring to the vehicle
