Trundle capable of lifting transverse shaft and avoiding vibration and vehicle

Abstract

The invention provides a trundle capable of lifting a transverse shaft and avoiding vibration and a vehicle and relates to the field of vehicles. The trundle capable of lifting the transverse shaft and avoiding vibration comprises a wheel body, the transverse shaft and a vibration avoidance component. The wheel body comprises an outer ring and an inner ring arranged in the outer ring, and the outer ring can rotate relative to the inner ring. The vibration avoidance component is arranged in the inner ring and comprises a movable block and a first elastic piece, the two ends of the first elasticpiece abut against the move block and the inner wall of the inner ring, and the transverse shaft is connected with the movable block and is higher than the center of the wheel body. By the adoption of the provided trundle capable of lifting the transverse shaft and avoiding vibration and the vehicle, the low-lying ground crossing capacity is higher. Buffering vibration avoidance can be achieved,the uncomfortable experience caused by a jolty road surface is overcome, no vibration avoidance device needs to be externally connected, no additional space is occupied, installation is easy, and theapplication range is wide.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a caster wheel capable of elevating a transverse axis and absorbing shocks and a vehicle. Background technique [0002] At present, the horizontal axis of the wheel is installed in the center of the wheel. The height of the horizontal axis from the ground depends on the size of the wheel, thus limiting the distance between the horizontal axis and the ground. When used on bumpy roads, if the wheel falls into a low-lying place, the horizontal axis is very easy. Hit the ground and cannot easily cross uneven roads. The wheel itself does not have a shock absorber system, which will bring discomfort to the user on bumpy roads. However, the external shock absorber takes up space, and the installation conditions are harsh, which cannot achieve the desired desired effect. Contents of the invention [0003] One of the objectives of the present invention is to provide a caster wheel capable of e...
