Mixer truck

Abstract

The invention provides a mixer truck. The mixer truck comprises a truck body as well as a mixing drum and riding wheels which are mounted on the truck body, wherein the axis of the mixing drum is inclined relative to a horizontal plane; the mixing drum is supported by the riding wheels; an inclination angle of the axes of the riding wheels relative to the horizontal plane is smaller than an inclination angle of the axis of the mixing drum relative to the horizontal plane; the axes of the riding wheels can be intersected with the axis of the mixing drum, or the axes of the rilding wheels are intersected with an axial space of the mixing drum. According to the technical scheme provided by the invention, a component force of the truck body in the horizontal direction, which is formed by the gravities of the mixing drum and matrials in the mixing drum can be reduced even eliminated, and thus the stress borne by the truck body can be reduced, the service life of the truck body is prolonged, the volumes and the weights of relevant support parts of the truck body and the mixing drum can be reduced, the occupied spaces of the truck body and the relavant suport parts are reduced and the dead weight of the truck body is reduced.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a mixer truck, especially to a mixer truck capable of reducing the horizontal force on the vehicle body. Background technique [0002] On the concrete mixer truck, in order to load more material in the mixing drum, the mixing drum is placed obliquely relative to the car body. [0003] like Figure 1 to Figure 4 As shown, the relationship between the mixing drum and the supporting wheel of the mixer truck in the related art is shown, as well as the stress condition of the supporting wheel. in, figure 1 It is a schematic diagram of the positional relationship between the mixing drum and the supporting wheel of the mixer truck in the related art; figure 2 Yes figure 1 A schematic diagram of rotation in direction A; image 3 It is a structural schematic diagram of a mixer truck in the related art; Figure 4 Yes image 3 Enlarged part B in the middle and schematic diagram...

AI Technical Summary

Problems solved by technology

It can be seen that the rear part of the car body 104 of the mixer truck is subjected to a backward component force F2, and similarly, the front part of the car body 104 is subjected to a forward component force, thereby causing the car body 104 and the mixing drum on the car body 104 to The supporting parts of 103 and supporting roller 102 are overstressed and easily damaged

To prevent the above failures, the volume and weight of the car body and the corresponding supporting parts will be increased, which not only takes up space, but also increases the weight of the vehicle, and increases cost and energy waste
