Thus, it is possible not only to improve the intensity of wheel hub 21, extends the service life of roller 2, it is also possible to improve the reliability being connected between roller 2 and wheel disc 111.
In one embodiment of the invention, as shown in figs, the outer surface of transmission component 1 can be provided with motor holding tank 112, motor 3 be contained in motor holding tank 112 at least partially, thus so that the location and installation of motor 3, can also improve the reliability being connected between motor 3 with transmission component 1 simultaneously.
In one embodiment of the invention, as shown in Figure 8, the axis of motor 3 is parallel with the axis of roller 2, and motor 3 and roller 2 are positioned at the same side (such as the downside of transmission component 1 shown in Fig. 8) of transmission component 1. The structure that thus can make drive wheel assemblies 100 is compacter, reasonable.
Further, as shown in Figure 10, transmission component 1 is about the plane symmetry of the axis through the axis of motor 3 and roller 2. Thus, it is possible to the transmission component 1 realized between different driving wheel assembly 100 exchanges, it is achieved the sharing of parts and standardization.
In one embodiment of the invention, as shown in figs, the outer surface of transmission component 1 is provided with catch 113, and catch 113 is between motor 3 and roller 2. Roller 2 thus can be avoided to collide with motor 3 in the process rolled, thus improving the security reliability of transmission component 1.
Preferably, as it is shown in figure 5, can be provided with installation portion 114 in drive wheel assemblies 100, installation portion 114 is two groups of the plane symmetry about the axis through the axis of motor 3 and roller 2. Thus, by utilizing the installation portion 114 of symmetry, same drive wheel assemblies 100 may be mounted at the symmetrical both sides of sweeping robot, thus the drive wheel assemblies 100 realized between multiple running gear 1000 is exchanged.
