KYB offers axial piston motors for many different industries and applications. From compact, fixed displacement piston motors to large, 2-speed motors with reductions gears and heavy-duty track drive motors available with a parking brake.
The piston motor has a variable displacement (2-speed) swashplate and incorporates a brake valve and mechanical brake. Combined with a case-rotation type planetary gear reducer, the KYB drive motor offers the following outstanding features:
Hydraulically balanced piston motor ensures high-pressure high-performance operation.
An offset-type 2-speed design ensures reliable changeover of the displacement by an external pilot control (speed ratios of between 1.5:1 and 2:1)
The motor offers a built-in double counterbalance valve and shockless crossover relief valve, providing speed control and braking with minimum shock.
The mechanical brake is a negative brake linked with the counterbalance valve. The brake is automatically activated or released when the vehicle stops or starts.
The case-rotation type gear reducer has improved durability and reliability due to high precision parts and an equally-loaded design.
The motor uses heavy duty bearings to ensure long life. Floating seals also prevent dust or water from entering into the motor.
