Problems solved by technology

[0004] However, after combining the spokes and the rim into a wheel, the rigidity of the proximal rim with the spoke support end will be greater than that of the far end rim without the spoke support end, resulting in a difference in the stiffness of the rim at both ends of the wheel
The difference in the stiffness of the rims on both sides of the wheel makes the strains of the rims on both sides of the wheel different during driving, which makes the force on both sides of the tire uneven during normal driving, resulting in great wear of the tire at the rim where the ground faces the spoke support end. The wear of the tire at the rim of the spoke support end is small, which causes partial wear of the tire, which in turn causes abnormal vibration of the vehicle, affects the handling performance of the car, and reduces the service life of the tire

Embodiment 1

[0029] figure 2 , W1 is the width of the proximal rim 2, that is, the horizontal distance from the connection between the proximal rim 2 and the intermediate portion 3 to the end of the proximal rim 2; H1 is the height of the proximal rim 2, that is, the close The vertical distance from the junction of the end rim 2 and the middle part 3 to the top of the proximal rim 2 .

Taking a 22.5X9.00 rim with a 15° deep groove as an example, the hook length L2 of the distal rim 4 is set to 17 mm, and the hook length L1 of the proximal rim 2 is set to 10 mm.

Abstract

The invention relates to a rim and a wheel with asymmetric design of rims on both sides, comprising a proximal rim, a middle part and a distal rim; the proximal rim and the distal rim are respectively arranged in the middle Both ends of the rim, and the proximal rim and the distal rim adopt asymmetric design, so that the rigidity of the distal rim is greater than that of the proximal rim; The rigidity of the distal rim is greater than that of the proximal rim. During use, the rigidity of the proximal rim increases due to the support of the spokes, so that the rigidity of the rims on both sides is consistent. In this way, the tire exerts an even force during the driving process, which can eliminate the eccentric tire wear caused by the different stiffness of the two ends of the traditional wheel, and prolong the service life of the wheel.

Description

technical field [0001] The invention relates to the technical field of wheels, in particular to a rim and a wheel with asymmetrical design of rims on both sides. Background technique [0002] The wheel is composed of a rim and a spoke. The open end of the spoke is assembled with the inner side of the mounting spoke surface of the rim, and then the rim and the spoke are formed into a whole by welding. [0003] Bead seats and rims are arranged on both ends of the rim, and the bead seats and the rims enable the tire to be well mounted on the wheel. like figure 1 As shown, in order to improve the service life of the tire, the rims on both sides of the existing rim are symmetrically designed, so that the rigidity of the rims on both sides of the rim is consistent. For example, the invention patent with the application number of CN201720251743.5 proposes a steel rim for a small agricultural vehicle, including a rim and a spoke, the rim includes a bead seat and a rim, the rim is ...
