Each of the frame assemblies includes a frame member which is pivotally secured at its rearward end to the rear drum support means. The first frame member is spaced above the truck frame and is secured thereto intermediate the length thereof. A length adjustable rod or turnbuckle means is pivotally connected at its forward end to the first frame member and is pivotally connected at its rearward end to the drum support means. The forward end of the first frame member is secured to a second frame member which is positioned forwardly thereof and which is secured to the truck frame member. Each of the frame assemblies provides a multiple point suspension system for the concrete mixer drum support means so that the drum support means will be maintained in its proper position with respect to the frame means and mixer drum when the truck is passed over rough terrain so as to prevent the mixer drum rail from moving out of engagement with the rear rollers on the rear drum support means.，下面是Support frame for a concrete mixer truck专利的具体信息内容。

3. The combination of claim 2 wherein said third and fourth frame members are spaced above said first and second frame members respectively.
4. The combination of claim 3 wherein said third and fourth frame members are secured to said first and second frame members respectively by a bolt means which limits the upward movement of said third and fourth frame members with respect to said first and second frame members but permits said third and fourth frame members to be deflected downwardly towards said first and second frame members.
5. The combination of claim 1 wherein said first and second support arms are each comprised of a length adjustable rod means pivotally connected to said first drum support means and said frame members.
7. The combination of claim 1 wherein each of said third and fourth frame members include a substantially horizontal lower end and a cambered upper end.
8. The combination of claim 7 wherein each of said third and fourth frame members include a substantially horizontal lower end and a cambered upper end.
8. In combination, a truck mixer having first and second, spaced apart frame members having rearward and forward ends, said first and second frame members being substantially horizontally disposed and having upper ends, said truck mixer also including a rotatably mixing drum, a first drum support means secured to the rearward ends of said first and second frame members and extending upwardly therefrom adapted to rotatably support the rearward end of the mixing drum thereon, a third frame member having rearward and forward ends, said third frame member being secured at its rearward end to said first drum support at the lower end thereof and extending forwardly therefrom above said first frame member, said third frame member being operatively secured to said first frame member, a fourth frame member having rearward and forward ends, said fourth frame member being secured at its rearward end to said first drum support at the lower end thereof and extending forwardly therefrom above said second frame member, said fourth frame member being operatively secured to said second frame member, a second drum support means operatively secured to the forward ends of said first and second frame members and adapted to rotatably support the forward end of the mixing drum thereon, a first elongated support arm secured at its rearward end to said first drum support means above the lower end thereof and secured at its forward end to said third frame member intermediate the length thereof, and a second elongated support arm secured at its rearward end to said first drum support means above the lower end thereof and secured at its forward end to said fourth frame member intermediate the length thereof, said first and second support arms maintaining said first drum support means in a proper relationship with respect to said mixing drum when said truck frame members are subjected to stress forces when the truck is driven over uneven terrain, said first and second support arms each being comprised of a length adjustable rod means pivotally connected to said first drum support means and said third and fourth frame members, a fifth frame member secured to said first frame member forwardly of said third frame member, a sixth frame member secured to said second frame member forwardly of said fourth frame member, said fifth and sixth frame members having rearward and forward ends, said second drum support means being secured to said fifth and sixth frame members, the rearward ends of said fifth and sixth frame members being connected to the forward ends of said third and fourth frame members respectively, said third and fourth frame members being spaced above said first and second frame members respectively, the rearward ends of said third and fourth frame members being pivotally connected to said first drum support means, said third and fourth frame members being secured to said first and second frame members respectively by a bolt means which limits the upward movement of said third and fourth frame members with respect to said first and second frame members but permits said third and fourth frame members to be deflected downwardly towards said first and second frame members.
