A mounting apparatus for a transit mixer support frame and pedestals including flexure joints and rotational joints. The flexure joints allow the front of the front pedestal and the back of the rear pedestal to move both vertically and laterally in response to conditional and dynamic loading of the transit mixer frame. The back of the front pedestal and the front of the rear pedestal are connected to the transit mixer frame through rotational joints. The rotational joints include support tubes extending transversely to the frame. Journal bearing portions are connected to the frame and fitted about the support tubes. The preferred embodiment of flexure joints utilize spring loaded bolts on the front of the front pedestal and the back of the rear pedestal. A second embodiment utilizes a transverse member with an oversized slot. A pin is connected to the pedestal and may move longitudinally and laterally within the slot. A third embodiment utilizes a transverse member and a single spring loaded bolt provides a simple three point mounting mechanism.
A mounting apparatus for a transit mixer having a frame, a front support pedestal and a rear support pedestal, both pedestals having a front and a back, comprising, a first rotational joint means pivotally connecting the back of the front pedestal to the frame, a second rotational joint means pivotally connecting the front of the rear pedestal to the frame, a first flexure joint means connecting the front of the front pedestal to the frame, a second flexure joint means connecting the back of the rear pedestal to the frame, said flexure joint means being arranged so as to allow relative movement between the pedestal and the frame.
In a mounting apparatus for a transit mixer vehicle having a mixer drum, a frame and front and rear pedestals for supporting the mixer drum on the frame, the improvement comprising, at least one of the pedestals having one longitudinal end pivotally connected to the frame by a rotational joint means and the other longitudinal end connected to the frame by a flexure joint means having means for allowing limited relative movement between the pedestal and the frame, the rotational joint means and flexure joint means serving to accommodate both the dynamic loads and deflections imposed due to the mobility and flexibility of the vehicle and the conditional loads imposed by operation of the transit mixer.
