Description

Technical Field

[0001] The utility model belongs to the field of wheel rims, and in particular relates to a tubeless bicycle rim and a wheel set with special characteristics. Background Art

[0002] At present, most bicycles use rims with inner tubes, and the rims and hubs are connected with steel wires. This type of wheel set is heavy, bulky, and has poor impact resistance, shock absorption, buffering ability, and comfort. During use, many times, collisions or force on sharp points can cause tire damage and rim deformation, or the entire wheel set is damaged and ineffective, causing serious traffic accidents. Utility Model Content

[0003] Therefore, in view of the multiple problems of existing vehicle sets, such as poor comfort, heavy weight, low impact resistance, low shock absorption performance, low buffering and the like, the utility model develops a radially reinforced, low tire pressure style tubeless spoke rim and wheel set.

[0004] The utility model aims to overcome technical deficiencies and provide a tubeless bicycle rim and wheel set with special characteristics, good comfort, light weight and high impact resistance.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The invention discloses a tubeless bicycle rim with special characteristics, comprising a rim body, a frame-shaped cross section, a cavity formed between an upper bridge plate and a lower bridge plate, an upper bridge plate and two symmetrically arranged upper supports connected to form a tire groove, the tire groove is in the shape of an open groove, a portion of the bridge plate close to the upper support is a tire lip seat, a tire pressing groove is in the middle of the bridge plate, a non-slip safety convex point is formed at the connection between the tire pressing groove and the tire lip seat, and spoke holes are arranged on the upper support or its reinforced edge.

[0007] Furthermore, the spoke holes are tapered through holes, which facilitate the locking of the spokes of the wheel rim and the spoke caps on the hub.

[0008] Furthermore, the upper support is a cavity structure. The design of the cavity can reduce the weight of the wheel rim.

[0009] (1) In the design of the wheel rim, the rim is divided into two layers, the inner and outer layers, which are processed into an integral rim using a bead and welding process. The inner layer is complete, which can ensure the vacuum degree of the entire spoke rim, and the outer layer is completed and closed.

[0010] (2) The spokes are fixed to the rim through tapered holes, and the spoke caps are on the hub to screw the spokes together.

[0011] The wheel rim can be divided into three forms. When the upper support is provided with spoke holes, the bottom of the upper support is arc-shaped, the lower bridge plate is divided into outer inclined surfaces on both sides and the spoke surface at the bottom, and the bottom and the lower bridge plate extend as one. At this time, the spoke holes are adapted to the cavity and are generally in an inclined state to increase radial rigidity.

[0012] Furthermore, when the spoke holes are arranged on the upper support reinforcement edge, the bottom of the cavity of the upper support is a plane with a thickened design, and the lower bridge plate is divided into outer inclined surfaces on both sides and the spoke surface at the bottom, and the outer inclined surface of the lower bridge plate is connected to the side of the bottom of the upper support close to the plane. At this time, the height of the cavity is higher than the reinforcement edge, which can enhance the radial rigidity and enhance the lateral rigidity at the same time.

[0013] The application also discloses a tubeless bicycle wheel set with special characteristics, wherein the spokes pass through the spoke holes on the wheel rim and are locked in the spoke cap holes on the hub.

[0014] Design of this application:

[0015] 1. The overall spoke style tubeless rim eliminates the inner tube and internal sealing material, greatly reducing the weight of the wheel set.

[0016] 2. The radial reinforcement design structure can spread the external impact force on the rim over a larger area, reducing the impact force per unit area.

[0017] 3. Spokes are elastic elements that can absorb a certain intensity of vibration and impact, and can better protect the rim when the rim is under stress, prevent deformation, and ensure the integrity of the vacuum structure.

[0018] The beneficial effects of the utility model are:

[0019] The present application discloses a rim and a wheel set. By applying this structured vacuum tire rim and wheel set to a bicycle, the comfort of a spoke wheel can be achieved while the problems of a vacuum tire rim can be solved. This achieves a combination of performance and comfort and promotes the development of vacuum tire spoke rims. BRIEF DESCRIPTION OF THE DRAWINGS
