Návrh hydraulického pohonu hydraulické ruky a posilovače řízení mobilního stroje

Abstract

The diploma thesis deals with the hydraulic actuator, hydraulic hand mobile machines. According to the power load on the machine are designed for linear motors move different parts of arms, rocking hydraulic motor needed to shoot the arm to the trailer and clearance lines. The hydraulic system operates in open loop, where the source of energy is external pressure hydraulic circuit mobile machines. The thesis deals with power steering in the second part. The work contains a detailed overview of the current function steering (mechanical - hydraulic, electro - hydraulic and electro - mechanical). Followed by draft power steering mobile machine. The final part is tested features power steering on a real circuit. The measured values are then constructed with different dependencies.
