The invention provides a rolling wheel, a sliding rail and a vehicle. The rolling wheel comprises a left wheel body and a right wheel body which are connected, and a containing cavity is formed between the left wheel body and the right wheel body in a buckled mode; a shaft body penetrates through the containing cavity, and the two ends of the shaft body penetrate out of the left wheel body and theright wheel body. The two groups of roller pin assemblies are arranged in the containing cavity; each set of roller pin assembly comprises a plurality of roller pins, the roller pins in the same setare parallel to the shaft body and are sequentially arranged in the circumferential direction of the shaft body, the two sets of roller pin assemblies are arranged in the axial direction of the shaftbody at intervals, the elastic piece is located in the containing cavity, and due to connection of the left wheel body and the right wheel body, the elastic piece is clamped between the two sets of roller pin assemblies. The left wheel body and the right wheel body are assembled into the assembly, the matching precision of the left wheel body and the right wheel body can be improved, when the idler wheel is applied to a sliding rail, the situation that movement is not concentric can be effectively prevented, the assembling process is simple and convenient, and the assembling efficiency can beeffectively improved.

    本发明提供了一种滚轮及滑轨和车辆,本发明的滚轮包括相连接的左轮体和右轮体,且于左轮体和右轮体之间扣合形成有容纳腔;轴体穿经容纳腔设置,且轴体的两端分别自左轮体和右轮体穿出;两组滚针组件设于容纳腔内,每组滚针组件均包括多个滚针,同一组的滚针均与轴体平行,并环轴体的周向依次设置,且两组滚针组件于轴体的轴向间距布置,弹性件位于容纳腔内,且因左轮体和右轮体的连接,弹性件被夹置于两组滚针组件之间。本发明所述的滚轮,通过将左轮体和右轮体装配为总成,可提高左轮体和右轮体的配合精度,在应用于滑轨上时,可有效防止出现运动不同心的情况,并且装配工艺简便,可有效提高装配效率。
