This creation is about a bicycle.

According to the modern people's awareness of environmental protection, riding a bicycle has become a tool for daily life. In addition, many enthusiasts like to ride bicycles on vacation and pursue speed. When the bicycle is in high speed, the wind resistance will block the bicycle. The maximum resistance of the Cavaliers, so road vehicles have become very popular in recent years, its streamlined design, lightweight materials and the Cavaliers' posture can be pushed down the body, making it easier to ride at high speeds and familiar bicycles.

However, the brake components of the conventional road vehicles are double-disc or double-clip (such as V-clip brakes), and when the double-clip brakes (such as V-clip brakes) are installed on the front wheels, the body is complicated due to the complicated structure. When the weight is increased and the wind resistance is increased, when the clip type brake is set in the rear wheel set, since the length of the rear wheel hub is generally 130 mm, the tension between the spokes is large and the lateral rigidity is insufficient; and the double-disc road car is equipped with the front wheel configuration. The disc makes the weight uneven, and the force of the disc brake is large. When the car is braked at high speed, it is easy to lock the knight with the front wheel, which is very dangerous; and the double-clip road car will be because of the rear. The configuration of the shifting gear on the right side of the wheel results in an uneven weight and there is a drawback to be improved.

Therefore, it is necessary to provide a novel and progressive bicycle to solve the above problems.

The main purpose of this creation is to provide a bicycle that can average the weight of the front wheel assembly and the rear wheel assembly, increase the lateral rigidity of the frame and the rear wheel, and avoid the excessive force of the front wheel brake to prevent the front wheel from being locked when braking. Let the knight carry the frame forward.

To achieve the above object, the present invention provides a bicycle including a frame, a front wheel assembly, a rear wheel assembly, a front brake assembly, and a rear brake assembly. The frame includes a front fork tube and a rear fork tube. The front wheel assembly is pivotally mounted to the front fork tube and includes a front wheel frame. The rear wheel assembly is pivotally mounted to the rear fork tube, and the rear wheel assembly is provided with a brake disc. The front brake assembly is disposed on the front fork tube and selectively clamps the front wheel frame. The rear brake assembly is disposed on the rear fork tube and selectively clamps the brake disc of the rear wheel assembly.

The structural features of the present invention and the intended effects thereof will be described below by way of a preferred embodiment, but are not intended to limit the scope of the present invention.

Referring to Figures 1 to 4, there is shown a preferred embodiment of the present invention. The bicycle of the present invention comprises a frame 1, a front wheel assembly 2, a rear wheel assembly 3, a front brake assembly 4 and a rear brake assembly 5. .

The frame 1 includes a front fork tube 11 and a rear fork tube 12.

The front wheel assembly 2 is pivotally mounted to the front fork tube 11 and includes a front wheel frame 21.

The rear wheel assembly 3 is pivotally mounted to the rear fork tube 12, and the rear wheel assembly 3 is provided with a brake disc 31.

The front brake assembly 4 is disposed on the front fork tube 11 and selectively clamps the front wheel frame 21.

The rear brake assembly 5 is disposed on the rear fork tube 12 and can selectively clamp the brake disc 31 of the rear wheel assembly 3. In the embodiment, the rear brake assembly 5 is a hydraulic brake caliper. In other embodiments, it can also be a mechanical brake caliper.

The front brake assembly 4 is a C-clamp brake structure, which can prevent the brake wheel from being too large to lock the front wheel assembly 2 and cause the knight to roll forward the frame 1, thereby improving the safety of the brakes, and the C-clamp structure The left and right weights of the front wheel assembly 2 can be prevented from being uneven (the disc type brake causes the front wheel weight to be biased toward the side on which the disc is mounted).

The rear wheel assembly 3 includes a rear hub 32. One end of the rear hub 32 is provided with a sprocket set 33. The rear hub 32 is provided with a flange 321 away from the side of the sprocket set 33. The brake disc 31 is fixed. The flange 321 is away from one side of the set of toothed discs 33.

The rear wheel assembly 3 includes a rear wheel frame 34, and a plurality of rear spokes 35 are connected between the rear wheel frame 34 and the rear hub 32. The rear spokes 35 are axially viewed by the rear wheel frame 34. Oblique to the radial direction of the rear wheel frame 34, the adjacent two of the rear spokes 35 are adjacent to the portion of the rear hub 32. Since the rear wheel assembly 3 supports the most weight of the knight, the adjacent two The intersection of the rear spokes 35 can have strong support. It is to be noted that, since the radial dimension of the rear hub 32 is long, the inclination of the rear spokes 35 disposed on the left and right sides of the rear wheel frame 34 can be symmetrical, and the rear wheel frame 34 can be improved. Lateral rigidity. It is worth mentioning that, in order to smoothly install the brake disc 31, the axial dimension of the rear hub 32 of the present invention needs to be lengthened by 5 to 10 mm, so that the weight of the left and right sides of the rear wheel frame 34 can be more evenly distributed. It also has a strong braking ability and is more stable when riding.

In addition, in the embodiment, the front wheel assembly 2 includes a front hub 22, and a plurality of front spokes 23 are connected between the front wheel frame 21 and the front hub 22, and the front wheel frame 21 is axially viewed. The spokes 23 are radially arranged along the radial direction of the front wheel frame 21. Since the front wheel assembly 2 supports the minimum weight of the knight, the radial arrangement has sufficient supporting force, and the radial arrangement is simple, and the high-speed riding can be reduced. Wind resistance by time.

The frame 1 includes a tube 13 including a rear lower fork tube 121 connected to the opposite lower end of the seat tube 13, the rear lower fork tube 121 including two side tubes 1211, The frame 1 includes a reinforcing tube 14 connected between the seat tube 13 and the side tube 1211 adjacent to the brake disc 31. The structural strength of the side tube 1211 can be improved to avoid the rear. When the brake assembly 5 performs braking, the stress on the side pipe 1211 is excessively deformed and bent, and the structural strength of the bicycle five-way pipe can be enhanced. The rear fork tube 12 includes a rear upper fork tube 122 connected to the opposite upper end of the seat tube 13 so as to be axially viewed by the rotation of the rear wheel frame 34, preferably the reinforcing tube 14 is preferably Parallel to the rear upper fork tube 122, which has the best reinforcing effect.

In summary, the bicycle of the present invention has a C-clip brake structure, which can prevent the brake wheel from being too large to lock the front wheel assembly and cause the knight to roll forward, and the weight of the left and right sides of the rear wheel frame More evenly, it is more stable when riding.

Moreover, the reinforcing pipe is connected between the seat pipe and the side pipe adjacent to the brake disc, and the structural strength of the side pipe can be improved to avoid the stress on the side pipe when the rear brake assembly is braked. It is too large and deformed and bent, and the structural strength of the five-way pipe of the bicycle can be strengthened.
