Abstract

The utility model relates to a shock absorbing device for bicycles, belonging to the technical field of bicycle fittings. The utility model is characterized in that two sets of damping springs are arranged on a front fork and a rear fork respectively, and the lower part of an outer tube is sheathed on the upper part of an inner tube. An upper spring seat is fixed on the upper part of the outer tube, a lower spring seat is fixed on the lower part of the inner tube, and a spring is arranged between the upper and the lower spring seats. Both the front wheel and the rear wheel of the utility model can accomplish the purpose of shock absorption. The utility model which has the advantages of simple structure, low cost, convenient installation and obvious shock absorbing effect reduces the damage of bicycle components and prolongs the service life of bicycles.

Description

Bicycle shock-absorbing device

The utility model is a kind of bicycle shock absorption device, belongs to the bicycle accessories technical field.

Existing bicycle damping or shock absorbing apparatus, all be installed on the front fork or vehicle seat of bicycle mostly, disclosed as Chinese patent 92232117.5,88201098 etc. is bicycle front-wheel shock absorption device, and the shock absorption device that has is positioned under the bicycle saddle, but the effect of damping is not quite desirable.As if the effect of damping on the trailing wheel that will be implemented in bicycle, this will relate to the vehicle frame part, because this part claimed structure is firm, be difficult for realizing.

The purpose of this utility model provides the device that a kind of bicycle wheels can both damping, and is simple in structure, convenient, feels comfortably cool in the time of can making bicycle rider walk scraggly road.

The utility model is to convert on the basis of the forward and backward fork of existing bicycle, the structure of front fork and back vent is identical, it is characterized in that being separately installed with on front fork and the back vent two cover damping springs, the bottom of outer tube (3) is enclosed within the top of interior pipe (4), be fixed with upper spring seat (1) on the top of outer tube (3), be fixed with lower spring cup (5) in the bottom of interior pipe (4), the spring (2) that is enclosed within on the inner and outer pipes is installed between two spring perches; Chain stay (6) respectively uses rotating shaft (8) to be connected with back vent (10), back vent (10) with the vehicle seat end of vehicle frame (7) with vehicle frame (7) lower end, chain stay (6).

The beneficial effect that the utility model is compared with background technology is the purpose that front and back wheel can both realize damping, and is simple in structure, with low cost, easy for installation, damping effect is obvious.When bicycle during in scraggly travels down such as mountain regions suffered vibrations absorbed by shock absorption device or weaken, the rider is felt comfortably cool, and has reduced the damage of bicycle part, prolonged the service life of bicycle.

Fig. 1 is mounted in the shock absorption device structural representation on bicycle front fork or the back vent, and Fig. 2 is the mounting structure scheme drawing of the utility model on bicycle.

Be described further below in conjunction with embodiment.

The front and rear fork partial reequipping of existing bicycle is become the structure that outer tube and interior pipe are arranged, the top of pipe in the bottom of outer tube is enclosed within, all be fixed with upper and lower spring perch on the inner and outer pipe, supported outer tube, make the certain distance range of maintenance between outer tube and the interior pipe by spring force.For preventing that spring from skidding off outside the spring perch, on upper and lower spring perch, be equipped with the set pin of fixing spring respectively.Outer tube (3) length of front and rear fork part is 240mm, and interior pipe (4) length is 310mm, under quiescent conditions in pipe box go into outer tube 100mm, the distance between the last lower spring cup is 240mm.Chain stay (9) is φ 12 with the shaft hole of vehicle frame (7) junction, lower end, and back vent (10) is φ 10 with the shaft hole of vehicle frame (7) vehicle seat one end junction, and chain stay (9) is φ 6 with the shaft hole of back vent (10) junction.

Claims

1, a kind of bicycle shock absorption device, be on the basis of the forward and backward fork that has bicycle now, to convert, the structure of front fork and back vent is identical, it is characterized in that being separately installed with on front fork or the back vent two cover damping springs, the bottom of outer tube (3) is enclosed within the top of interior pipe (4), be fixed with upper spring seat (1) on the top of outer tube (3), be fixed with lower spring cup (5), the spring (2) that is enclosed within on the inner and outer pipes is installed between two spring perches in the bottom of interior pipe (4); Chain stay (6) respectively uses rotating shaft (8) to be connected with back vent (10), back vent (10) with the vehicle seat end of vehicle frame (7) with vehicle frame (7) lower end, chain stay (6).
