Problems solved by technology

[0004] The present invention solves the problem that the spoke structure of the existing wheel spoke structure is symmetrical, so that the natural frequency of the wheel itself and the transmission path generated by the vibration are basically maintained unchanged, and the wheel cannot better adapt to complex road conditions and complex load stresses, thus Reduce the use comfort and reliability of the wheel to the wheel, and affect the current situation such as reducing the fatigue life of the wheel, which can change the natural frequency of the wheel to a greater extent, change and adapt to the vibration transmission path, and improve the use of the wheel. Spoke construction of asymmetrical high vent wheel for comfort and fatigue life

Embodiment 1

[0022] figure 1 , figure 2 , image 3 In the illustrated embodiment, a spoke structure of an asymmetric high-ventilation wheel includes a rim 20 and spokes, and the wheel may preferably adopt a five-spoke wheel structure. Among the many spokes 10 that constitute the spokes, any two or three of the spoke main bodies 12 are selected for radial slight inclination (see figure 2 ) to form an asymmetric structure in which some of the spokes are radially inclined; any three or four of the spokes are provided with a through hole 11 in the middle area of ​​the spoke, forming an asymmetric structure in the middle area of ​​the spoke. The inclination angle of slight inclination is in the range of -5º~+5º from the horizontal plane. Each spoke has a different angle of inclination across the range of inclination angles. The shape of the through hole is circular, oval or square through hole. A through hole is provided in the central region of one of the spokes, and a vent hole with a ...

Embodiment 2

[0024] figure 1 In the shown embodiment, take the central axis formed by the opposite ventilation holes corresponding to the spokes with through holes as the reference central datum line (see figure 1 H-H center datum line in ), the transverse connecting surface formed at the crossing position of the two spokes on both sides of the ventilation hole and the wheel mounting hole surface (see figure 1 The horizontal connection surface where the C-C horizontal connection line is located), the horizontal connection surface C is slightly tilted and rotated with reference to the H-H central datum line, forming an asymmetric structure in which the horizontal connection surface is slightly tilted and rotated. Select 1 to 2 lateral connecting surfaces to perform slight tilting rotation with reference to the center reference line. Others are identical with embodiment 1.

Embodiment 3

[0026] figure 1 In the shown embodiment, in the plurality of spokes constituting the spokes, the welded connection end face 40 of each spoke and the rim is welded with any 2-3 welded seam structures of the spokes and the rim welded end face. Asymmetric construction of slightly inclined welds. The inclination angle of the radially slightly inclined weld is in the range of -5º~+5º. Others are identical with embodiment 1 or embodiment 2.

Abstract

The invention discloses a wheel arm structure of an asymmetrical high-vent wheel. The wheel arm structure comprises a rim and an arm of the wheel. In multiple spokes of the arm of the wheel, any two or three spoke bodies are selected and inclined slightly in the radial direction, and an asymmetrical structure of the part of spokes inclining in the radial direction in the multiple spokes is formed; and through holes are formed in the middle regions of any three or four spokes, and an asymmetrical structure of the middle regions of the spokes is formed. By means of the wheel arm structure, the inherent frequency of the wheel can be changed to a greater degree; and although the inherent frequency changes slightly, the whole vehicle wheel structure can be changed to adapt to the vibration transmission path, the use comfort of the wheel is improved, and the anti-fatigue life of the wheel is prolonged.

Description

technical field [0001] The invention relates to a wheel hub, in particular to a spoke structure of a high-ventilation-hole wheel used in a high-ventilation wheel hub. Background technique [0002] What existing automobile wheel hub adopts all is to adopt to comprise members such as wheel rim, wheel spoke and the high ventilation hole that is formed between mutual spoke and wheel rim. However, the existing wheel hub has a spoke structure in which the spokes of the symmetrical shape structure are used to form a symmetrical spoke structure, and the contact area between the spoke and the rim is a symmetrical shape structure, which makes the natural frequency of the wheel itself and its vibration. The generated transmission paths are basically kept unchanged, and the wheels cannot better adapt to complex road conditions and complex load stresses, thereby reducing the comfort and reliability of the wheel-to-wheel use, and affecting the fatigue life that the wheels can withstand. ...
