The specific embodiment
The utility model discloses a kind of axle system, improve vehicle operating stability.The utility model also provides a kind of bogie truck with above-mentioned axle system.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to shown in Fig. 1 and Fig. 2 the first structural representation of the axle system that Fig. 1 provides for the utility model embodiment; The second structural representation of the axle system that Fig. 2 provides for the utility model embodiment.
As shown in Figure 1, the axle system that the utility model embodiment provides, comprise wheel to and axletree 2, the static unbalance position of two wheels 1 of wheel centering is in same sagittal plane and be positioned at the same side of axletree 2.
It should be noted that, above-mentioned sagittal plane is through the plane of the axis of axletree 2.
The axle system that the utility model embodiment provides, at wheel 1 in the installation process of axletree 2, the static unbalance position of two wheels 1 of wheel centering is arranged on the same sagittal plane through axletree 2, and be positioned at the same side of axletree 2, the static unbalance position of two wheels 1 is arranged at same direction, two wheels 1 are synchronously carried out because of jolting of causing of static unbalance and jumping phenomena, effectively improve the relative stability of two wheels 1 in rotation process, and then improved the stability of vehicle operating.
