Fig. 2 is the rear perspective view of the utility model three axial momentums wheel mechanical test with the anchor clamps specific embodiment.
Embodiment
Three axial momentums of the utility model wheel mechanical test is with the practical implementation of anchor clamps Fig. 1, shown in Figure 2 for example; These anchor clamps are mainly by the substrate 1 that is used for being fixedly connected with testing table and be fixed in the pedestal 2 that substrate 1 upper surface is used for installing at the trial three axial momentums wheel and form, and four jiaos of substrate 1 offer the through hole that is used to wear coupling bolt respectively.Pedestal 2 is mainly by forming to mount pad 4 with vertical axes to the horizontal axis mount pad 3 of two corresponding settings of different installment states with three axial momentums wheel horizontal axis and vertical axes; Horizontal axis mount pad 3 is rectangular structure with vertical axes to mount pad 4; Horizontal axis mount pad 3 is equipped with momenttum wheel installation station and the stepped laying that is intersected vertically and constituted the evagination angular structure by plane and facade from bottom to top with vertical axes on mount pad 4; Wherein, The facade 31 of horizontal axis mount pad 3 is fixed on the substrate 1, and its plane 32 vertical fixing are in facade 31 upper ends; Vertical axes is vertically fixed on to the facade 41 of mount pad 4 on the plane 32 of horizontal axis mount pad 3 and is parallel with the facade 31 of horizontal axis mount pad 3, and vertical axes is vertically fixed on its facade 41 to the plane 42 of mount pad 4, makes that pedestal 2 is whole to be the notch cuttype layout.Offer the connecting hole that is used to install bolt at horizontal axis mount pad 3 and vertical axes corresponding respectively momenttum wheel base on each joint face of mount pad 4; Wherein, The plane 32 of horizontal axis mount pad 3 and vertical axes offer respectively on the facade 41 of mount pad 4 and are used for and corresponding four bolt mounting holes 6 that communicate of three axial momentums wheel base side plate connecting hole, offer respectively on the plane 42 of mount pad 4 in facade 31 and the vertical axes of horizontal axis mount pad 3 to be used for taking turns a corresponding air nozzle hole and two bolt mounting holes 5 that are connected of base top board valve portion with three axial momentums.
