Abstract
The utility model relates to a vehicle shock absorber, comprising a front fork casing tube, a spring tube and a lever arm, wherein, the front fork casing tube is welded with the spring tube into integration through a connecting plate, and the bottom is connected with the lever arm through a support arm and a shaft pin; a spring draw rod positioned in the spring tube is connected with the lever arm through a sliding shaft pin, and the spring draw rod is provided with a shock-proof spring, a collision reducing spring and a regulating nut; one end of the lever arm is provided with a slotted hole connected with a front shaft. The utility model can be matched with the bicycle for using, can reduce the vibration generated in bump and the vibration generated in collision.
Description
The utility model belongs to the bicycle field, particularly a kind of bicycle shock-proof device.
Existing automatic shock-proof device is generally the car front fork and Shock absorber is the simple type Shock absorber of one, and the Shock absorber lower end is fastened on the preceding fork shaft.During vehicle ', Shock absorber can absorb from the ground-surface pitch force.Though can have cushioning effect to jolting of bicycle quick, when bicycle generation minor impact, still not have the effect of slowly-releasing bump vibrations." bicycle damper " (notification number CN2087173U) of Patent Office of the People's Republic of China's bulletin on October 23rd, 91 contains front-wheel bumper and rear wheel shock-absorbing device.The front-wheel bumper is made up of fixation fork, front fork, preceding decoupling rod and spring, and the rear wheel shock-absorbing device is made up of spring, back decoupling rod and sleeve pipe.This bumper can overcome the shortcoming that causes the bicycle vibrations owing to Uneven road, but the bicycle to being clashed into, it is unsatisfactory to alleviate the bump vibrating effect.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art part, provides a kind of damping effect better and can alleviate subtracting of bump vibrations and hit Shock absorber.
The technical solution of the utility model is such.This Shock absorber comprises front fork sleeve pipe, spring tube and throw of lever, can be welded as a whole by connecting panel and spring tube with the front fork sleeve pipe that preceding justice cooperates.The front fork sleeve bottom is connected with throw of lever with pivot pin by support arm.The spring pull bar that is arranged in spring tube is connected with throw of lever by the slip pivot pin, shock-proof spring is housed on the spring pull bar and subtracts to hit spring and adjustment nut, and after installing, spring tube and throw of lever closed contact.One end of throw of lever has the slotted eye that can be connected with front axle.Be lower than the level attitude of slotted eye on the throw of lever with the position of the supporting pin hole of pivot pin.The utility model is installed in when using on the bicycle, and owing to 15 ° of angles of front fork form the level error that the support arm hole is lower than more than 10 millimeter of front-axle hole, the anterior center of gravity of car is lower than preceding axle horizontal.During bicycle running, pitch force is absorbed by shock-proof spring by throw of lever, spring pull bar.When bump took place, the throw of lever vertical angle was greater than 45 °, and this impact is hit spring and absorbed by subtracting.
The supporting use of the utility model and bicycle except that can alleviating the vibrations of jolting, also can alleviate the bump vibrations, has improved the safety factor and the class of bicycle.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, each component structural of the utility model is: 1-front fork sleeve pipe 2-support arm 3-connecting panel 4-spring tube 5-shock-proof spring 6-subtracts and hits spring 7-spring pull bar 8-adjustment nut 9-cover of dust 10-throw of lever 11-pivot pin 12-slip pivot pin 13-slotted eye 14-pad 15-dottle pin
As can be seen, the front fork sleeve pipe (1) that can cooperate with front fork is welded as a whole by connecting panel (3) and spring tube (4) from the figure.Front fork sleeve pipe (1) bottom is connected with throw of lever (10) with pivot pin (11) by support arm (2).The spring pull bar (7) that is arranged in spring tube (4) is connected with throw of lever (10) by slip pivot pin (12), and shock-proof spring (5) is housed on the spring pull bar (7), subtracts and hits spring (6) and adjustment nut (8), and dottle pin (15) and pad (14) are housed therebetween.A cover of dust (9) is equipped with at the mouth of pipe place of spring tube (4).One end of lever (10) has the slotted eye (13) that can be connected with front axle.Add man-hour, be lower than preceding axle horizontal in order to make car front fork center of gravity, to increase the relative stability of bicycle running, the pin hole position that throw of lever (10) is gone up and pivot pin (11) is supporting is lower than the level attitude of slotted eye (13).
Claims (2)
1. a bicycle use low center of gravity subtracts and hits Shock absorber, comprise front fork sleeve pipe (1), shock-proof spring (5) and subtract and hit spring (6), it is characterized in that the front fork sleeve pipe (1) that can cooperate with front fork is welded as a whole by connecting panel (3) and spring tube (4), front fork sleeve pipe (1) bottom is connected with throw of lever (10) with pivot pin (11) by support arm (2), the spring pull bar (7) that is arranged in spring tube (4) is connected with throw of lever (10) by slip pivot pin (12), shock-proof spring (5) is housed on the spring pull bar (7) and subtracts and hit spring (6) and adjustment nut (8), an end of throw of lever (10) has the slotted eye (13) that can be connected with front axle.
2. a kind of bicycle use low center of gravity according to claim 1 subtracts hits Shock absorber, it is characterized in that throw of lever (10) the position last and pin hole that pivot pin (11) is supporting is lower than the level attitude of slotted eye (13).
