SUMMARY

The discussion focuses on calculating the wheel radius for a hydraulically driven vehicle using specific parameters such as motor power, required horsepower, and pump RPM. Key values include a motor power of 5 kW, a gear ratio of 5, and a calculated RPM on the wheel of approximately 94.49. The torque at the wheel is calculated to be 2352.93 Nm, leading to a tractive effort of 357.25 N. The conversation emphasizes the importance of understanding the relationship between motor specifications and wheel performance.

PREREQUISITES
  • Understanding of hydraulic systems and their components
  • Familiarity with torque and power calculations
  • Knowledge of gear ratios and their impact on RPM
  • Basic principles of vehicle dynamics and tractive effort
NEXT STEPS
  • Research hydraulic system design for vehicles
  • Learn about torque and power relationships in mechanical systems
  • Study the effects of gear ratios on motor performance
  • Explore vehicle dynamics, focusing on tractive effort calculations
USEFUL FOR

Engineers, vehicle designers, and students in mechanical engineering who are involved in the design and analysis of hydraulic vehicles and their performance metrics.

Welcome to PF.

Is this a hydraulically driven vehicle ?
Does it have normal steering or is it a skid steer vehicle ?
How many motors are used to drive the 4 wheels ?
Are the wheel motor(s) in series, or in parallel ?
How can the kW at the H-motor, be greater than the e-motor ?

Please attach a sketch of the device, and/or a hydraulic diagram.
