Abstract

The utility model relates to a bicycle vibration absorber, composed of a swing rod, a stable guide rod and a vibration-absorbing spring, wherein, one end of the swing rod is provided with a hinge end, and the other end is provided with the fixing slot of a wheel shaft; the stable guide rod is a half circular arc shape rod and is fixedly connected with the swing rod, and the pin hole of the hinge end of the swing rod is the centre of circle of the circular arc of the stable guide rod; the vibration-absorbing spring is sheathed on the stable guide rod. The utility model has the advantages of simple structure, can effectively reduce the vibration of the bicycle generated in running, so the rider feels stable and comfortable.

Description

The bicycle shock absorption device

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

Ordinary bicycle, its vehicle frame and axletree are rigidly connected, and damping mainly is to rely on the spring that is located under the vehicle seat, and its damping effect is not obvious, and vibrations are still bigger when riding.

The purpose of this utility model is to provide a kind of can reduce vibrations, bicycle shock absorption device simple in structure effectively.

The utility model by swing arm, stablize guide rod and damping spring is formed, an end of described swing arm has articulated joint, the other end has the axletree hold down groove; Described stable guide rod is a semicircular arc bar, the one end is fixedly connected on the axletree hold down groove place of swing arm, its circular arc is the center of circle with the pin-and-hole of swing arm articulated joint, and described damping spring is placed in to be stablized on the guide rod, and the stable guide rod of both ends of the spring is provided with the spring catch nail.

In the practicality, hinged between the articulated joint of swing arm and the back vehicle frame with pin, the vehicle frame place of intersecting with stable guide rod is provided with set collar, stablizing guide rod passes from ring, equal shock absorption device on the vehicle frame of wheel both sides, the vertical tremor of vehicle frame when riding is by the effect of the swing of swing arm and spring and alleviate, eliminate.When using the utility model on front-wheel, can adorn an adapter plate on front fork, set collar is located on the adapter plate, and front fork and swing arm are hinged.

The utility model is simple in structure, shakes in the time of can weakening bicycle running effectively, and the cyclist is felt steadily, and is comfortable.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model running condition scheme drawing.

With reference to accompanying drawing, of the present utility model by swing arm (7), stablize guide rod (2) and damping spring (5) forms, institute Swing arm one end of stating has articulated joint (6), and this articulated joint can be a U jaw, also can be a plate, the articulated joint other end Fixedly groove (1) of axletree is arranged; Stable guide rod is a semicircular arc bar, and the axletree that its end is fixedly connected on swing arm is fixed The groove place, its circular arc is take the pin-and-hole of swing arm articulated joint as the center of circle, and the damping spring is placed in to be stablized on the guide rod, and the stable of both ends of the spring led Bar is provided with spring retaining screw (4). In the practicality, hinged with pin between the articulated joint of swing arm and the rear vehicle frame, with stable guide rod The vehicle frame place of intersecting is provided with fixing ring (3), stablizes guide rod and passes from ring, and axletree is fixed in fixedly groove of swing arm axletree In. When front-wheel uses the utility model, can fill a fixed head (8) at front fork, fixedly be located on the fixed head, from Driving front fork and swing arm are hinged. The vertical tremor of vehicle frame in riding is alleviated, is disappeared by the effect of the swing of swing arm and spring Remove.

Embodiment 1

Shock absorption device in this example by swing arm, stablize guide rod and damping spring is formed, articulated joint is the U jaw, only installs at trailing wheel, front-wheel is still the same with ordinary bicycle.

Embodiment 2

Compare with embodiment one in this example, the front and back two-wheeled all is equipped with shock absorption device of the present utility model, adorns a circular adapter plate on front fork, and set collar is located on the adapter plate, and bicycle front fork and swing arm are hinged.

Claims

A kind of bicycle shock absorption device by swing arm, stablize guide rod and damping spring is formed, is characterized in that an end of described swing arm has articulated joint, and the other end has the axletree hold down groove; Described stable guide rod is a semicircular arc bar, the one end is fixedly connected on the axletree hold down groove place of swing arm, its circular arc is the center of circle with the pin-and-hole of swing arm articulated joint, and described damping spring is placed in to be stablized on the guide rod, and the stable guide rod of both ends of the spring is provided with the spring catch nail.
