-ra'-fll Hydraulic Motor* W WHEEL MOTORS TECHNICAL CATALOGUE CATALOGO TECNICO MOTOR IRUOTA o COMMON DEFINITIONS In this catalogue and most of the SAI documents the following specific terminology Is used to describe specific key points of the SAI products. The peak values indicate the maximum working conditions that the product can withstand. This means that the component can in fact work at its peak working conditions for a period of time that does not exceed 1% per minute and not more than 10 times per hour. The continuous working condition values are the ones that can be applied...

WHEEL MOTORS TECHNICAL CATALOGUE CATALOGO TECNICO MOTOR IRUOTA MAXIMUM MOTOR TORQUE F - traction force (N) W - vehicle weight (kg) T - motor torque (Nm) D - external wheel diameter (m) n - number of hydraulic motors R - sin (slope angle0) or traction resistance (%) Swivelling cylinder the cylinder (1) always remains aligned with the eccentric (3) of the crank, thus eliminating the stress between the walls of the piston (2) and the cylinder. The articulation of the cylinder is done by the trunnions (4) that ensure low specific loads. Piston: the pistons transfer the load to the shaft through...

-ra'-fll Hydraulic Motor* W WHEEL MOTORS TECHNICAL CATALOGUE CATALOGO TECNICO MOTOR IRUOTA DISPLACEMENT VARIATION Over the years SA1 has developed a wide range of dual and variable displacement motors whilst keeping the outside dimensions the same within the size of the fixed displacement motor series originally made by SAI. The dual and variable displacement motor technology satisfies a wide operational range request. The same power can be utilized from high torque-low speed to high speed-low torque working conditions. With the SAI technological advances the user can optimize the operating...

-ra'-fll Hydraulic Motor* W WHEEL MOTORS TECHNICAL CATALOGUE CATALOGO TECNICO MOTOR IRUOTA DUAL DISPLACEMENT MOTOR This type of control switches between two displacement positions: minimum and maximum. The change of position of the directional valve occurs via a pilot signal PIL(c),. When there is no pressure In the pilot line, the valve maintains (or changes It into) maximum displacement. When the pressure in the pilot line is between 20 and 30 bar, the valve shifts the spool, changing the displacement to minimum. Pilot pressure is affected by the case pressure and the motor speed. The...

WHEEL MOTORS TECHNICAL CATALOGUE CATALOGO TECNICO MOTOR IRUOTA CHARACTERISTICS AND INDICATIONS HIGH STARTING TORQUE The design of the radial piston motor with crankshaft and oscillating cylinders ensures very high starting torque efficiencies, especially at high pressures which are required in most mobile applications. The mechanical efficiency of the SAI motor is typically higher than 90% at 400 bar. The high starting torque is usually required when the vehicle is at standstill or during low speed operations. For example when the mobile application accelerates from standstill or when it...

-ra'-fll Hydraulic Motor* W WHEEL MOTORS TECHNICAL CATALOGUE CATALOGO TECNICO MOTOR IRUOTA o CAVITATION RESISTANCE The piston retaining rings ensure that the pistons remain in full contact with the eccentric, no matter what the pressure conditions inside the cylinders or the motor casing are. The retaining force counteracts continuously the separating force, thus preventing lifting, tilting or hammering of the piston during cavitation.
