Abstract
The utility model relates to a shock reduction device for bicycles, particularly for mountain bicycles. On most of the existing bicycles, shock is reduced in a mode that tension springs and springs are arranged under saddles. The effect of vibration reduction is not obvious. Even more, some bicycles do not have the shock reduction device. The utility model is composed of a spring 1, a turn blocking pin 2, a casing 3, a dust-proof cover 4, and a core axle, and is installed on the connection of a saddle and a bicycle body. The utility model reduces shock by using an assembly and concentrating mode, can reduce 90 percent of shock, and has the advantages of simple fabrication, simple installation, beautiful appearance, and durability.
Description
The utility model relates to a kind of shock attenuation unit of bicycle.
At present popular on the market locate driving, from the common car of riding instead of walk to all kinds of racing cars, mountain bike, from the imported car to the domestic car, except that under cushion, adopting extension spring and spring to carry out all not having more effective shock attenuation unit the small vibration damping.All kinds of bicycles under steam, when particularly running into Uneven road, it is very big to jolt, and makes the cyclist very uncomfortable, this sensation adopt the injection molding seat and do not have the racing car of actv. shock attenuation unit and mountain bike on particularly evident.
The purpose of this utility model provides a kind of simple in structure, and is easy for installation, is suitable for the efficient shock attenuation unit that various bicycles are used.The method that realizes purpose is to add in the connection place of bicycle seat and vehicle body to shoot the shaft type shock attenuation unit, and this device does not change the bicycle Parameter of Overall Design.
Below in conjunction with accompanying drawing the structure that plays the shaft type shock attenuation unit and the method that installs additional are added and to give detailed description:
Fig. 1 is for playing shaft type damping device structure scheme drawing;
Fig. 2 shoots shaft type shock attenuation unit position scheme drawing for bicycle adds;
Fig. 3 is for playing shaft type shock attenuation unit housing cutaway view;
Fig. 4 is for playing shaft type shock attenuation unit mandrel constructional drawing.
Play the shaft type shock attenuation unit as shown in Figure 1, by damper spring 1, spline pin 2, housing 3, several parts such as dust protecting cap 4 and mandrel 5 are formed.Housing 3 is an end osed top hollow tube, have on the tube wall spline pin-and-hole 2 ', be used to insert the spline pin, as shown in Figure 3.Mandrel 5 structures as shown in Figure 4, an end that inserts housing has a spline hole 6, the other end has filler port 7 to be communicated with oil groove 8, so that it is often oily in shock absorber, the effect in spline hole 6 is with spline pin 2 and spline pin-and-hole 2 ' form together stop motion mechnism, prevent mandrel 5 left-right rotation and make the bike saddle left-right rotation in housing 3, mandrel 5 can not be ejected in housing 3.Dust protecting cap 4 is made by telescopic flexible pipe, and purpose is to prevent that dust from entering in the shock attenuation unit.Shock attenuation unit is installed in bicycle seat and vehicle body connection place, as shown in Figure 2.Seat binding nut B is unclamped in choosing when installing additional
1With the adjusting nut B on the spider
2, taking out original strut bar, in the end insertion spider with shock attenuation unit assembly A band housing 3, an end of belt carcass axle 5 inserts in the seat, regulates height, tightens binding nut B respectively
1With adjusting nut B
2Get final product.When the people rode bicycle, mandrel 5 pressurizeds were downward, were about 2/5 section of vibration damping scope.As the road surface of jolting, mandrel 5 pumps with seat and human body together at the effect F of spring 1 connection, offsets the vibration of jolting that causes because of Uneven road, and through testing, the effectiveness in vibration suppression that installs additional behind the shock attenuation unit can reach 90%.Because the difference of human body weight can then can make the people of Different Weight all reach same effectiveness in vibration suppression by the elastic force of large, medium and small three different stages design change spring 1.
The utility model is owing to adopt assembly to concentrate vibration damping, the vibration damping scope of having avoided extension spring that existing bicycle adopts and multiple spot spring damping to bring is little, cyclist's center of gravity is difficult for the weakness such as stable, greatly improved effectiveness in vibration suppression and cyclist's steady reliability, making is also arranged simultaneously, attractive and durable advantage is installed simply.
The mountain bike of giving birth that the utility model is adapted at putting on market at present most (being the vehicle that seat does not have spring) is upper to be used, can also be on racing car and common scooter direct application.
Claims (3)
1, a kind of bicycle use shock attenuation unit is characterized in that by damper spring 1, spline pin 2, and housing 3, dust protecting cap 4 and mandrel 5 are formed.
2, shock attenuation unit according to claim 1 is characterized in that being installed in bicycle seat and vehicle body connection place.
3, shock attenuation unit according to claim 1 and 2 is characterized in that spline hole 6 is arranged on the mandrel 5, oiling 7 and oil groove 8.
