自动搅拌车的方向盘是搅拌车的控制部件和转向系统的一部分。整个转向机构的原理是通过齿轮齿条将圆周运动变为直线运动,推动车轮转动。在物理学中,方向盘本身就是一个杠杆。搅拌车方向盘的半径是力臂的长度。方向盘越大,越省力。
The steering wheel of the automatic mixer is a part of the control component and steering system of the mixer. The principle of the whole steering mechanism is to change the circular motion into the linear motion through the gear rack to drive the wheel to rotate. In physics, the steering wheel itself is a lever. The radius of the mixer steering wheel is the length of the force arm. The larger the steering wheel, the less effort.
搅拌车的舵机可分为几种类型。常见的是齿轮齿条转向机和循环球转向机。齿轮齿条式转向系统已迅速成为密炼机和小型密炼机常用的转向系统。其工作机理非常简单。搅拌车的齿轮齿条组用金属管包裹。
The steering gear of mixer truck can be divided into several types. The common ones are rack and pinion steering gear and recirculating ball steering gear. Rack and pinion steering system has rapidly become a common steering system for internal mixer and small internal mixer. Its working mechanism is very simple. The gear rack set of the mixer truck is wrapped with metal pipes.
齿条的每个齿端伸出金属管,并用拉杆连接在一起。小齿轮与转向轴相连。转动方向盘时,齿轮转动,带动齿条运动。搅拌车机架每个齿端的横拉杆连接到转向轴的转向臂上。
Each tooth end of the rack extends out of a metal tube and is connected together with a pull rod. The pinion is connected to the steering shaft. When the steering wheel is turned, the gear rotates to drive the rack. The tie rod at each tooth end of the mixer frame is connected to the steering arm of the steering shaft.
目前许多搅拌车采用循环球转向系统。车轮的拉杆与齿轮齿条式转向系统略有不同。搅拌轮的拉杆与齿轮齿条转向系统略有不同。循环球系统的动力转向原理与齿轮齿条系统相似。其辅助动力还通过向金属块的一侧注入高压液体来提供。
At present, many mixer trucks use the circulating ball steering system. The pull rod of the wheel is slightly different from the rack and pinion steering system. The pull rod of the mixing wheel is slightly different from the gear rack steering system. The power steering principle of the recirculating ball system is similar to that of the rack and pinion system. The auxiliary power is also provided by injecting high-pressure liquid into one side of the metal block.

此外要想搅拌车延长使用寿命就需要做到几点:当轴承的寿命终了时,电动机运行的振动及噪声将明显增大,检查轴承的径向游隙达到下列值时,即应更换轴承。使用环境应经常保持干燥,电动机表面应保持清洁,进风口不应受尘土、纤维等阻碍。应保证电动机在运行过程中良好的润滑。
In addition, in order to prolong the service life of the mixer truck, it is necessary to do several things: when the service life of the bearing ends, the vibration and noise of the motor will increase significantly. When the radial clearance of the bearing reaches the following values, the bearing should be replaced. The operating environment should always be kept dry, the motor surface should be kept clean, and the air inlet should not be obstructed by dust, fiber, etc. The motor shall be well lubricated during operation.
自动搅拌车更换绕组时必须记下原绕组的形式,尺寸及匝数,线规等,当失落了这些数据时,应向制造厂索取,随意更改原设计绕组,常常使电动机某项或几项性能恶化,甚至于无法使用。当电动机的热保护连续发生动作时,应查明故障来自电动机还是超负荷或保护装置整定值太低,消除故障后,方可投入运行。拆卸电动机时,从轴伸端或非伸端取出转子都可以。
When replacing the winding of the automatic mixer truck, the form, size, number of turns, wire gauge, etc. of the original winding must be recorded. When these data are lost, they should be obtained from the manufacturer, and the original design winding should be changed at will, which often deteriorates the performance of one or more items of the motor, or even can not be used. When the thermal protection of the motor acts continuously, it is necessary to find out whether the fault is from the motor or overload or the setting value of the protection device is too low. The motor can be put into operation only after the fault is eliminated. When disassembling the motor, take out the rotor from the shaft extension end or non extension end.
