摘要： PROBLEM TO BE SOLVED: To realize operation analysis of a transmission with a highly-accurate and small-sized device. SOLUTION: Fluid pressure pump motors 24, 28 are connected respectively to the input/output shaft of the transmission 12 and driven, and a load is applied thereto. A working fluid is supplied to the fluid pressure pump motors 24, 28 through a high-pressure pipe 36 from a high fluid pressure pump 38, and the working fluid delivered from the motors 24, 28 is returned to the high fluid pressure pump 38 through a low-pressure pipe 40. The inertia on the input side can be reduced up to the same degree as an engine by using the input fluid pressure pump motor 24. In addition, the total amount of the working fluid can be suppressed by forming a circuit for the working fluid as a closed circuit, and the whole device can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide a friction tester for directly measuring a load applied to a test piece, achieving a relatively-simple mechanism, and easily maintaining the measurement precision.
SOLUTION: The friction tester comprises: a L-shaped base 1 having a X-Y plane and a Y-Z plane; a test bench 2 rotated or moved in a plane parallel to the X-Y plane; a Z-axis movement means 3 for applying the frictional load to one friction test piece 9a in the Z-axis direction; a Z-axis displacement means 5 displaced by the frictional load applied by the Z-axis movement means 3 in the Z-axis direction; an in-plane displacement member 6 provided between the Z-axis movement means 3 and the other friction test piece 9b, and displaced in a plane parallel to the X-Y plane by a frictional force between the frictional test pieces 9a, 9b; a Z-axis displacement sensor 7 for detecting a displacement of the Z-axis displacement member 5 in the Z-axis direction; and an in-plane displacement sensor 8 for detecting an in-plane displacement of the in-plane displacement member 6. The friction tester is characterized in that the Z-axis displacement sensor 7 measures the frictional load, and that the in-plane displacement sensor 8 measures the frictional force.

摘要： PROBLEM TO BE SOLVED: To provide a testing method and a testing device of a metal belt for a metal belt continuously variable transmission in which characteristics such as friction, abrasion, etc. between an element and a ring can be evaluated independently of characteristics between a pulley and the element, and in an almost similar state as actual equipment.
SOLUTION: The testing method of the metal belt for the metal belt continuously variable transmission is provided with a plurality of elements 2 and the endless belt ring 3. At least one element 2 is arranged in the same way as the motion state, held not to substantially move. Tension is applied between the held element 2 and the ring 3 brought in contact with the element 2 in the same way as in motion, and the ring 3 is made to move back and forth in the moving direction of the belt with respect of the element 2.
