Hydraulic pump and motor

  1. Aug 18, 2012 #1
    i have a problem

    i have a motor 100hp and constant 2500rpm

    i need to connect to him hydraulic pump, that will rotate hydraulic motors connected to the wheels. i need to get about 80 N*m on each wheel

    how to solve this problem?
    what formulas i need?

    Well based on the power of the motor and the rpm, you can get the output torque of the motor. This will then transfer to the wheels.

    hm... it's to difficult for me... :-/

    motor make 100hp at 3000rpm. so pump also rotates at 3000rpm

    what a flow and torque that produces pump?

    thank u

    "Calculating Full-load Torque" will help you get the torque produced by the motor. I am not sure how your motor is connected to your wheel system.

    Do you have schematic or something,cause as rock.freak667 said it`s not clear from your first post.

    this is a schematic of my project

    so i need to choose pump and hydraulic motors to get speed of car about 70mph and torque about 120 N*m

    the TC engine rotates constantly 2500rpm and make 100hp and 150N*m

    so i need help in choosing of pump and hydraulic motors

    thank u!
