elastic rim

Abstract

The invention discloses an elastic wheel which comprises an outer frame, at least two spokes and a shaft seat. The spokes are evenly disposed between the outer frame and the shaft seat and are in distorted arc structures. The spokes have the function of deformation, the same as the springs. Micro deformation of the spokes reduce vibration and also enables the stress of the outer frame to be absorbed by the deforming spokes, the outer frame evenly and flexibly deforms, and accordingly jumping is avoided and comfort is better.

Description

technical field [0001] The invention relates to a rim structure, in particular to an elastic rim with elastic spokes. Background technique [0002] In order to move the car body, wheels are generally installed at the bottom of the car body. The traditional wheels are made up of rims and tires, and the rims include outer frame 1, some spokes 2 and axle seats 3 (which can be matched with Figure 6 to Figure 9 As shown), the tire ring is set on the outer frame and directly contacts with the ground, which can play a buffering role and reduce vibration. The power that drives the vehicle body to move. [0003] Existing wheel spokes have various structures, among which plate-like ribs are one of the spoke structures. Because the ribs are relatively strong, they can play a supporting role in the running of the tire, but the number of ribs is usually small, which leads to the deformation of the outer frame. Uneven deformation. Such as Figure 6 , 7 As shown, it is a rim structure...

Problems solved by technology

[0003] Existing wheel spokes have various structures, among which plate-like ribs are one of the spoke structures. Because the ribs are relatively strong, they can play a supporting role in the running of the tire, but the number of ribs is usually small, which leads to the deformation of the outer frame. Uneven deformation

like Image 6 , 7 As shown, it is a rim structure with plate-shaped spokes. During driving, the rim of this structure has no deformation because the rib 2 is relatively strong, and the position of the rib corresponding to the outer frame is not easily deformed, and the outer frame 1 Other positions are deformed due to no rib support, which makes the outer frame undulating, so the comfort is very poor

[0004] Figure 8 and Figure 9 There are two other rim structures. The rims of these two structures are the same as the aforementioned rims. The center of the rib 2 coincides with the center of the axle seat 3. When the rim is stressed, the rib 2 supports the outer frame 1. The outer frame at the supported part is not easy to deform, and the outer frame at the unsupported part deforms more seriously, which affects the comfort

[0005] From the force analysis of the above-mentioned existing wheel rims during driving, it can be seen that the reason why the outer frame of the existing wheel rims fluctuates during driving is mainly because the rigidity of the plate-like spokes is too strong, and the elasticity is insufficient, and the stress of the wheel rim The direction of the force coincides with the center of the spokes and the center of the axle seat. When the force is applied, the spokes are not deformed, only the outer frame is undulating and deformed. Especially for the rim with a small number of spokes, the undulating state is more serious, and the car body may even produce severe damage. Vibration, poor comfort, room for improvement
