Definitions
- the present invention relates to a mixer drum driving device for driving a mixer drum of a mixer car.
- a mixer truck is a vehicle that carries raw concrete such as mortar or ready-mixed concrete from a ready-mixed concrete factory to a construction site in a mixer drum that is rotatably mounted on a frame.
- the mixer truck rotates the mixer drum forward when transporting the ready-mixed concrete and agitates the ready-mixed concrete with a plurality of spiral blades installed in the mixer drum. Further, the mixer truck is configured so that the ready-mixed concrete in the mixer drum can be discharged by rotating the mixer drum in the direction opposite to the normal rotation. When arriving at the concrete placement site, the mixer truck rotates the mixer drum in reverse to supply ready-mixed concrete to the placement site.
- a mixer vehicle engine As a drive source for the mixer drum, a mixer vehicle engine is generally used. Specifically, the power of the engine is transmitted to the hydraulic pump via PTO (Power Take Off), the hydraulic oil discharged from the hydraulic pump is supplied to the hydraulic motor, and the hydraulic motor driven by the hydraulic oil rotates. To rotate the mixer drum.

Therefore, the space for mounting the mixer drum on the gantry has been pressed. When the mixer drum mounting space is pressed in this way, the loading amount of ready-mixed concrete is reduced, and the transport efficiency is lowered.

Increasing the strength of the gantry or chassis frame increases the vehicle weight of the mixer truck (the weight of the vehicle alone). Since the maximum loading capacity of ready-mixed concrete loaded on the mixer drum is the value obtained by subtracting the vehicle weight from the total vehicle weight, the heavier the mixer truck weight, the lower the maximum loading capacity of ready-mixed concrete and the better the transport efficiency. It will decline.
