What are the types of steering systems for electric pallet truck?
The steering system of electric pallet truck can be divided into two categories according to the energy used for steering: mechanical steering system (also known as manual steering system) and power steering system. The mechanical steering system completely relies on the physical energy of the driver to manipulate the steering and overcome the steering resistance moment. The pallet truck manufacturer tells everyone that in the power steering system, the energy consumed to overcome the steering resistance moment is provided by the prime mover, and the driver manipulates the system to control the steering.
According to the different working principles of the steering system, the steering system of electric pallet truck can be divided into three categories: mechanical steering, power assisted steering (mechanical steering with power assisted device), and full hydraulic power steering. The steering system can be divided into multiple modes according to the number of steering wheels, such as single wheel deflection, double wheel deflection, and all wheel deflection. Pallet truck manufacturer tell everyone that the two-wheel deflection steering system is the most widely used.
The components of the dual wheel deflection mechanical steering system of an electric pallet truck can be summarized into two parts: one is the steering component, which mainly includes the steering wheel, steering shaft, and steering gear. Steering gear is a special decelerating transmission device used to amplify the steering torque acting on the steering wheel and then transmit it to the steering wheel. It is the main component in the mechanical steering system to ensure lightweight steering; The steering wheel is a control element, and the steering shaft is the transmission shaft from the steering wheel to the steering gear. If the three are on the same axis, they can be assembled as a whole, which is called a steering gear assembly. If the overall layout of the vehicle requires, the steering wheel and the steering gear can not be on the same draw line (the axes intersect or parallel), and the two are connected by the steering shaft and universal joint. The second is the steering transmission mechanism, which is a group of spatial force transmission rods, including steering verticals, woven longitudinal links Steering knuckle static and single trapezoidal mechanism or sector plate and double trapezoidal mechanism, etc. The pallet truck manufacturer told everyone that it transmits the amplified steering torque to the left and right turning joints: the steering wheel deflects.
In the dual wheel deflection power steering system of electric pallet truck, the components of the mechanical steering system are basically retained, while the power steering movement is inserted to keep the length of the tie rod unchanged. The ball socket and torsion spring are blocked by the screw plug to prevent them from falling out. There are various types of steering for electric pallet truck, and small vehicles usually adopt simple mechanical manual steering systems, such as 0.41 and 0.5t electric pallet truck. The pallet truck manufacturer tells everyone that electric pallet truck with a capacity of more than 1 ton basically use a power steering system.

New energy forklift power system controllerIn the electric forklift power unit, when the forward contactor is closed, the motor is in a forward rotation state; Whereas, when the reverse contactor is closed, the motor is reversed. By changing the direction of the armature current or excitation current, or by changing the polarity of the excitation winding, the commutation control of the motor is realized. However, the use of two sets of excitation windings with opposite windings will lead to a complex structure and an increase in the volume of the motor, so the first two methods are more commonly used in practicalDo you like ?0

Electric forklifts vs. internal combustion forkliftsHowever, there are also some drawbacks to internal combustion forklifts. First of all, diesel engines are more expensive to run, especially against the backdrop of the current surge in oil prices. Secondly, the internal combustion forklift is noisy and vibrate, and the operating noise of the diesel engine has an irreversible impact on the human body. In addition, the exhaust gas pollution is serious, even if the processor is installed, it will cause environmental pollution, and it is necessary to clean up the dust regularly, which is more cumbersome to maintain, and can easily lead to oil pollution problems on the site.Do you like ?0
