Description

Tank body operating system of concrete mixer truck

Technical Field

Background

In the concrete mixer truck, the rotary power of the tank body is derived from the engine of the concrete mixer truck, the power of the engine is transmitted to the hydraulic pump through the transmission shaft in the main gearbox (when the rotational speed and steering control is carried out on the tank body, the concrete mixer truck is in a stop advancing state, the main gearbox of the engine is positioned in a neutral position, the hydraulic pump pumps hydraulic oil into the hydraulic system to provide power for a rear hydraulic motor, and the hydraulic motor transmits the power to the tank body after being decelerated by the tank body speed reducer.

In the prior art, the steering system for controlling the rotation direction and rotation speed of the tank in a concrete mixer is generally: the hydraulic control device is connected with an upper swing arm (the swing arm is connected with a control valve integrated on the hydraulic pump, the control valve is operated by changing the position of the swing arm, so that the hydraulic oil flow direction of a rear hydraulic motor can be changed, the steering of the hydraulic motor is changed, and finally the steering control of a tank body is realized), a connecting rod mechanism is connected, a flexible shaft is led out from the connecting rod mechanism to a cab, and the steering control of the tank body is realized by pulling the flexible shaft to change the position of the swing arm by a driver. In order to control the steering and the rotating speed of the tank body during parking, a steering control pull rod is led out of the connecting rod mechanism and directly communicated to the tail of the vehicle, so that the steering control pull rod is convenient to control at the tail of the vehicle manually. In order to control the rotating speed of the tank body at the same time, an accelerator control pull rod is led out from an engine accelerator interface to the tail of a vehicle and is connected with a steering control pull rod to realize linkage control.

The control system is composed of pure mechanical parts, and not only is the structure complex, but also manual operation is needed. When the mutually moving parts lack lubricating oil, there are operational difficulties, mechanical failures are liable to occur, and maintenance and repair are not easy. In addition, since the operating systems are generally made of carbon steel materials, the operating systems are heavy and do not meet the requirement of increasing attention of customers for light weight. In addition, the above-described steering system is limited to being operable only in the cab and the tail of the vehicle, and has limitations in steering position. In order to solve the above problems, it is necessary to develop a manipulation system which is simple in structure, convenient to operate, easy to maintain, and light in weight, and can realize remote operation at any position.
