Abstract
The double spring continuous type shock absorber, belongs to the vehicle vehicles suspension unit area of technology. Must solve the technical question is provides a kind to reduce by the double spring structure continuous type inspires the installment. Solves its technical question technical plan to contain the supporting plate, gets down the supporting plate, the piston, the piston barrel, the connecting rod, level of springs and two levels of springs. The connecting rod installs on on supporting plate, its terminal installs the piston, the piston loads in the piston barrel. On on the supporting plate has the fixing lug. The next supporting plate center-section has raised along, the lower extremity has the fixing lug. In level of springs sleeves the cable muff outside the piston barrel, its under cable muff in under supporting plate spitting along outside, level of springs installs in the spring sleeve. Two levels of springs install in on supporting plate and between a level of springs sleeve. The shock absorber applies in front of the motorcycle the trailing wheel reduces inspires. The beneficial effect is reduces inspires the effect well, ever not as overweight reduces as the overload inspires the function is continual, structure simple, the cost is low.
Description
Technical field
Belong to vehicle vehicles suspension unit area of technology.
Background technique
Respectively there is a single spring cushion to play damping effect about the trailing wheel of motorcycle.The general design load 120 kg of motorcycle is equivalent to the weight that two people drive, and its vibration damper generally plays damping effect in the 120 kg load range.If load surpasses 120 kg, then a single spring cushion is just inapplicable, does not have damping effect.China utility model patent ZL02220404.0 " the two back of rocking arm type vibration damping equipment " patent specification discloses a kind of vibration damper, between rear wheel fork and vehicle frame, except adorning a traditional single spring cushion, also installs a rocking arm type list spring cushion additional.Under not overweight condition, traditional single spring cushion plays damping effect, and under overweight condition; the rocking arm of rocking arm type list spring cushion rotates an angle under overweight action of gravity; the following fixedly ear of vibration damper moves down with rear wheel fork and directly contacts, and lever type shock absorber has promptly begun damping effect.But the damping effects of the two back of rocking arm type vibration damping equipments are the discontinuous of burst, promptly just play damping effect overweight when reaching to a certain degree, can produce bump in short-term, give the rider with uncomfortable sensation.
Summary of the invention
Technical problem to be solved provides a kind of continous way vibration damping equipment that dual spring is arranged.
The technological scheme that solves its technical problem comprises upper supporting plate, lower carrier plate, piston cylinder, piston rod, piston, one-level spring, one-level spring spool and two-level spring.There is the fixedly ear of going up that connects vibration damper and vehicle frame the upper end of upper supporting plate.Lower carrier plate and piston cylinder are one, and there is the following fixedly ear that connects vibration damper and rear wheel fork the lower end of lower carrier plate, and there is the convex edge of its diameter greater than the piston cylinder external diameter in the stage casing of lower carrier plate.Piston rod is contained on the upper supporting plate, the direction activity up and down therein in the piston cylinder of packing into of the lower end of piston rod dress piston, piston.The endoporus of one-level spring spool is divided into two sections, and endoporus epimere internal diameter is a bit larger tham the piston sleeve external diameter, and endoporus hypomere internal diameter is a bit larger tham the diameter of the convex edge of lower carrier plate, and its hypomere of outside that the epimere of one-level spring spool is enclosed within piston cylinder is enclosed within the outside of the convex edge of lower carrier plate.The less one-level spring of the coefficient of stiffiness is contained in the one-level spring spool, and its lower end contacts with the upper-end surface of the convex edge of lower carrier plate, and its upper end contacts with the upper-end surface of one-level spring spool endoporus hypomere.The two-level spring that the coefficient of stiffiness is bigger is contained between the upper-end surface of the lower end surface of upper supporting plate and one-level spring spool.Damping effect is divided into the two-stage, and under promptly not overweight condition of phase I, the one-level spring plays damping effect under by the action of gravity of vehicle frame by upper supporting plate, two-level spring and the transmission of one-level spring spool; In second stage is under the overweight condition, and the decrement of one-level spring reaches capacity, and only plays transmission strength, becomes the lower fulcrum of two-level spring, and two-level spring plays damping effect under the effect by the overweight load of vehicle frame transmission.The action of phase I and second stage interconnects, and its damping effect is continuous, and the rider can not produce unexpected sensation.
The diameter of the convex edge in lower carrier plate stage casing also can equal the external diameter of one-level spring spool, certain distance is arranged between the upper-end surface of the convex edge of the lower end surface of one-level spring spool and lower carrier plate at ordinary times, the one-level spring is contained in the one-level spring spool, its lower end surface contacts with the upper-end surface of the convex edge of lower carrier plate, and its upper-end surface contacts with the upper-end surface of the endoporus hypomere of one-level spring spool.Under not overweight condition, the one-level spring plays damping effect; Under overweight condition, the contacted position, convex edge that the one-level spring spool moves down into its lower end surface and lower carrier plate becomes the lower fulcrum of two-level spring, and two-level spring plays damping effect.
Beneficial effect: be applied to motorcycle, can be used as the vibration damping equipment of motor cycle rear wheel, also can be used as the front-wheel vibration damping equipment; Can be used alone as vibration damping equipment, also can be used as two backs vibration damping equipment.Beneficial effect is that vibration damping usefulness is good, and never overweight be continuous to overweight its damping effect, the rider does not have the sensation of sudden change, and is simple in structure, cost of production is low, is the Updated product of motorcycle vibration damping device.
