Problems solved by technology

In addition, the bearings for the output shaft of the barrel flange supported by obliquely positioned tapered roller bearings are made such that the torsional rigidity of the bearings is also limited to allow compensating movements
[0003] However, tolerating said twist and its compensation creates fatigue problems
Also, the problem of vibrations caused by dynamic loads cannot be solved in a satisfactory manner by currently known solutions

Embodiment Construction

[0027] figure 1 with figure 2 The mixer drive 1 shown in is seated via a mixer support 2 on a support block 3 supported by a running gear frame 4 of a truck mixer not shown in other respects. In this connection, the truck mixer comprises in a manner known per se a multi-axle running gear with corresponding gears supporting said running gear frame 4 on which is also known per se The operator's cabin is arranged in a manner, while the mixer driving device and the mixing drum 5 driven by it are arranged behind the operator's cabin.

[0028] Such as figure 1 As shown, the mixer drive 1 comprises a drive part 6 for generating a rotary drive movement and a drive transmission 7 which is driven by the drive part 6 on the input side and rotates on the output side Drive the mixing drum 5. In the illustrated embodiment, the drive transmission 7 is made as a two-stage planetary gear, the sun gear of the first stage of which is driven by the drive member 6 via the input shaft 8 .

Abstract

The invention provides a building material stirrer including a stirring cylinder and a driving transmission device connected to the stirring cylinder, the stirring cylinder can be rotatably driven by the driving device of the stirrer, meanwhile, the stirring cylinder rotatably supports at a framework component of the stirrer by the driving device of the stirrer at an end face part thereof; the framework component of the stirrer is specifically the framework component of a walking device, and the driving device of the stirrer includes a driving component which is specifically a hydraulic motor. In accordance with the invention, the building material stirrer is characterized in that the driving device of the stirrer movably supports at the framework component of the stirrer by a movable support device so as to allow the inclination movement; and the invention is characterized in that the stirrer is fastened to a shell of the driving transmission device.

Description

technical field [0001] The invention relates to a construction material mixer comprising a mixing drum capable of being driven in rotation by a mixer drive, said mixing drum being rotatably supported at one of its end faces at a mixer frame part by the mixer drive, so that The mixer frame part is specifically a walking device frame part, and the mixer driving device has a driving part and a driving transmission device connected to the mixing drum, and the driving part is specifically a hydraulic motor. Background technique [0002] Construction material mixers in the form of truck mixers, which are commonly used to supply ready-mixed concrete to construction sites, often have large dynamic forces acting on the mixing drum, e.g. when driving through bumpy access roads, often under heavy load The mixing drum will cause considerable dynamic bearing force. On the other hand, when running on uneven ground, the running device frame supporting the mixing drum will be twisted, so t...
