Abstract

The utility model relates to a damping light bicycle. The front fork and the front damping series are combined to make the shock of the front wheel damped, and the rear fork and the rear damping series are connected to the frame to make the shock of the rear wheel damped. The utility model has the advantages of comfortable ride, firmness and reliability.

Description

Damping light bicycle

The utility model relates to a kind of portable bicycle that has shock absorption device.

Existing bicycle shock absorption device relies on the elasticity saddle of bicycle fully, because Uneven road forms to jolt and makes moderate progress, but front fork does not have cushioning effect, so cyclist's both hands still are subjected to than thump, especially ride after distance or mountain area path ride, feel exhausted and do not survey.

The purpose of this utility model provides a kind of portable bicycle of car load damping, and front and rear wheel absorbs ground-surface impact, alleviates the sense of fatigue of rider.

The utility model is equipped with front fork 2 on vehicle frame 1 be 5 with the preceding damping that is connected front fork, and back vent 3 is 4 with the back damping that is connected back vent and vehicle frame, forms the portable bicycle that front and back wheel has shock-absorbing function simultaneously.

The damping simultaneously of this car front and rear wheel adds the spring shock absorption effect of upper saddle seat, and the impulsive force that is delivered on cyclist's health alleviates greatly, rides for a long time and feels tired in the uneven road surface buttocks is unlikely.

Accompanying drawings is as follows:

Back vent 3 front ends are connected with vehicle frame 1 rear crotch 1-2, and bakelite cover 3-1 penetrates rear crotch hole 3-7, and bolt 3-5 penetrates the gum cover hole, tightens with packing ring 3-2,3-3, nut 3-4 again.

Back damping is that 4 upper boom 4-1 are connected with vehicle frame 1 sleeve pipe 1-1, upper end hole penetrates gum cover 4-4, threading 4-5 in the gum cover, use bolt 4-8 again, packing ring 4-6, nut 4-7 tightens, there are two guide-track grooves the upper boom lower end, lower beam 4-10 in groove by bolt 4-13, sleeve pipe 4-14, packing ring 4-15, nut 4-16 crosswise fixed, lower beam can slide in groove, between the two pad 4-3 spring 4-9 is arranged, upper boom has adjustment hole, gives tight power with pin 4-2 regulating spring, stomidium penetrates gum cover 4-12 under the lower beam, threading 4-11 in the gum cover is connected with bicycle rear axle again, and back vent 3 rear ends also are connected with rear axle.

Respectively there is a double jaw 2-1 described front fork 2 lower ends, be connected through bolt 5-5, nut 5-6, pad 5-4 with rocking bar 5-1 mid point, there is a copper sheathing 5-2 at the rocking bar center, the supporting crank swing, rocking bar one end is connected with front axle, the other end has sleeve pipe 5-7 by two plain film 5-8 clampings between two plain films, plain film and rocking bar tighten up through bolt, nut; There is a regulating part 5-10 front fork 2 upper ends, are connected with rocking bar through spring 5-9, and spring gives tightness and can be changed by regulating part; The end face of brake disc 5-13 is by bolt 5-11 fixed muffle 5-12, and sleeve and rocking bar are drawn close and prevented the brake disc rotation.

Front-wheel is connected with rocking bar 5-1, spring 5-9, on uneven road surface.When front-wheel is impacted, be support with the rocking bar center, be radius with the rocking bar radius, rotate backward, corner can be greater than 90 °, and trailing wheel is connected with back vent 3, decoupling rod and spring 4-9, also can do upper and lower motion, therefore damping significantly reaches the comfortable effect of riding.
