• the shock absorber is mounted on top of the front end of the upper fork arm.

A multi-bearing-point independent suspension, comprising:

• an upper fork arm, a lower fork arm, elastic elements, a shock absorber, fork arm positioning shafts, link rods and output levers;
• wherein:
• the upper fork arm and the lower fork arm are A-shaped structural parts;
• front ends of the upper fork arm and the lower fork arm are respectively connected with an upper suspension point and a lower suspension point of a wheel through main pins;
• rear ends of the upper fork arm and lower fork arm are connected to the vehicle frame by fork arm positioning shafts respectively;
• two fork arm hanging pivots extend from bottom of the front portion of the upper fork arm;
• a lower end of each fork arm hanging pivot is connected to an output lever by means of a link rod;
• a middle portion of the output lever is hinged to the vehicle frame by means of an output lever rotating shaft;
• an elastic element is arranged between bottom of another end of the output lever and the vehicle frame, and
• the shock absorber is mounted on top of the front end of the upper fork arm.

A multi-bearing-point independent suspension, comprising:

• an upper fork arm, a lower fork arm, elastic elements, a shock absorber, fork arm positioning shafts, right-angled output arms, and connecting arms;
• wherein:
• the upper fork arm and the lower fork arm are A-shaped structural parts;
• front ends of the upper fork arm and the lower fork arm are respectively connected with an upper suspension point and a lower suspension point of a wheel through main pins;
• rear ends of the upper fork arm and lower fork arm are connected respectively to the vehicle frame by the fork arm positioning shafts;
• each of opposite sides of a front portion of the upper fork arm is hinged to a connecting arm;
• another end of the connecting arm is hinged to an end of a right-angled output arm,
• another end of the right-angled output arm is connected to an and of the elastic element;
• another end of the elastic element is fixed to the vehicle frame;
• the right-angled output arm has a right-angled output arm rotating shaft;
• the right-angled output arm rotating shaft is pivotally connected to the vehicle frame, and
• the shock absorber is mounted on top of the front end of the upper fork arm.

A multi-bearing-point independent suspension, comprising:

• an upper fork arm, a lower fork arm, a shock absorber, fork arm positioning shafts, a torsion spring and a torsion spring seat;
• wherein:
• the upper fork arm and the lower fork arm are A-shaped structural parts;
• front ends of the upper fork arm and the lower fork arm are respectively connected with an upper suspension point and a lower suspension point of a wheel through main pins;
• rear ends of at least one of the upper fork arm and the lower fork arm are connected to the vehicle frame by a torsion spring and a torsion spring seat;
• wherein when vertical bouncing of the wheel brings about an upward movement of the front end of the upper fork arm, the upper fork arm rotates about a rear fixing point such that two torsion springs arranged symmetrically on two sides produce a torsional deformation which has the effect of shock absorption, and
• the shock absorber is mounted on top of the front end of the upper fork arm.
