Description

Technical Field

[0001] This utility model belongs to the field of road bicycle technology, specifically relating to a bicycle front fork with a damper. Background Technology

[0002] Road bikes are a type of racing bicycle designed for speed. Therefore, they need to be lightweight, fast, and minimize wind resistance. As a result, conventional road bikes do not have a suspension system, especially in the front fork. Mountain bikes often add front fork shock absorbers to reduce the impact of bumps. However, if a road bike were to adopt the front fork suspension system of a mountain bike, it would need to incorporate the mountain bike's front fork structure. This structure consists of two large spring shock absorbers, which would significantly increase the weight of the road bike and also compromise the front fork's wind resistance, increasing the drag coefficient. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A bicycle front fork with a damper, comprising a front fork assembly consisting of a front fork and a sleeve, characterized in that: a shock-absorbing component is provided inside the sleeve;

[0005] The shock absorption assembly includes a damper and an elastic element. The elastic element is sleeved on the outside of the damper, with one end of the elastic element abutting the fork and the other end abutting the sleeve.

[0006] One end of the damper is disposed inside the sleeve, and the other end is connected to the fork. When the damper is compressed inward to reduce shock, the elastic element resets the damper.

[0007] Furthermore, the damper includes a movable end and a hydraulic cylinder end;

[0008] The movable end is located inside the sleeve, and the cylinder end is connected to the front fork through a sleeve. The outer circumferential surface of the sleeve is a slope. The front fork is provided with a receiving groove that matches the slope. The bottom of the receiving groove is provided with a through hole. The first fastener fixes the cylinder end in the receiving groove through the through hole.

[0009] The cylinder end is also slidably connected to a sliding sleeve, which is fixedly connected to the sleeve. The sleeve slides up / down on the cylinder housing at the cylinder end through the sliding sleeve.

[0010] Furthermore, the cylinder housing at the cylinder end is a square column, and the sleeve and sliding sleeve are both matched with the square column. The sleeve is provided with a second fastener, and an anti-rotation pin is provided on one side of the fork. The second fastener is used to fix the sleeve and the sliding sleeve together, and the anti-rotation pin is used to restrict the rotation of the sleeve in the receiving groove.

[0011] Furthermore, the fork assembly also includes a connecting sleeve disposed between the fork and the sleeve.

[0012] Furthermore, the sleeve is also connected to a connector via a thread, the connector having a boss, one end of the elastic element abutting against the boss, and the other end abutting against the fork.

[0013] Furthermore, the elastic element is provided with washers at both ends, namely a first washer and a second washer, which respectively abut against the inner ends of the connecting sleeve.

[0014] The beneficial effects of this utility model are:

[0015] This utility model uses a damper and a spring sleeve. The damper is fixed inside the sleeve, and the cylinder end of the damper is fixed to the bicycle front fork. After the spring is sleeved, the spring can support the damper to open. Through the sleeved cooperation of the damper and the spring, the vibration transmitted from the bicycle front wheel can be effectively reduced, playing a shock absorption and buffering role. At the same time, the shock absorption component of this utility model is located inside the front fork sleeve, which does not affect the wind resistance of the vehicle and also takes into account the aesthetics.

[0016] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.
