Flexible element

A spring element, comprising:

• a pair of end plates, one of which is connectable to a frame or a wheel axle of a vehicle to provide a single coupling of said spring element to said vehicle;
• a rubber body disposed between the end plates;
• and
• a mechanical connection member extending through said rubber body and being coupled between said pair of end plates in such manner that said connection member limits a separation distance between said pair of end plates, said mechanical connection member including a stub extending through one of said pair of end plates, said stub being shaped to correspond to a shape of a through-passage in one of said vehicle frame or said wheel axle such that when said stub is inserted into said through-passage, relative rotation between said stub and said through-passage is prevented.

A spring element, comprising:

• a pair of end plates, one of which is connectable to a frame or a wheel axle of a vehicle to provide a single coupling of said spring element to said vehicle;
• a rubber body disposed between the end plates;
• and
• a mechanical connection member extending through said rubber body and being coupled between said pair of end plates, said mechanical connection member including a first coupling device having a first U-shaped link element at one end thereof and a single stub at the other end thereof extending through said one of said pair of end plates, a second coupling device having a second U-shaped link element at one end thereof, said second U-shaped link element being fixedly connected to the other of said pair of end plates, and a link member coupled between said first U-shaped link element and said second U-shaped link element;
• wherein said stub engages with a corresponding through-passage in said frame or said wheel axle for formation of said single coupling.

A spring element configured to transmit compression forces and tensile forces between a frame member and a wheel axle of a vehicle, said spring element comprising:

• a rubber body having a first end and a second end;
• a first end plate covering said first end;
• a second end plate covering said second end;
• and
• a mechanical connection member extending through said rubber body for fixed attachment to said second cover plate, said mechanical connection member fixedly attached to said first end plate through which a stub portion of said mechanical connection member protrudes, said stub portion having an internal thread, said spring element having attachment to said vehicle by a single coupling of said mechanical connection member to one of said frame member and said wheel axle using a bolt, positioned in a through-passage of one of said frame member and said wheel axle, said bolt to be received in said internal thread, said stub adapted to prevent rotation thereof during engagement of said bolt with said internal thread.

A spring element configured to transmit compression forces and tensile forces between a frame member and a wheel axle of a vehicle, said spring element consisting of:

• a rubber body having a first end and a second end;
• a first end plate covering said first end;
• a second end plate covering said second end;
• and
• a mechanical connection member extending through said rubber body for fixed attachment to said second cover plate, said mechanical connection member fixedly attached to said first end plate through which a stub portion of said mechanical connection member protrudes, said stub portion used to attach said spring element to said vehicle.
