  • Gearbox simulation test bench
    Patent number: 7644630
    Abstract: The invention relates to a test bench that reproduces the performance of a gearbox. The invention consists of: at least one gearshift module (2) comprising a linear motor (12) and a ball joint (14) that can be used to convert a linear motion of the motor (12) into a rotational motion of a gearshift shaft (5) and a force sensor (17) that can be used to measure the force applied to the gearshift shaft (5). In particular embodiments of the invention, the test bench also comprises a vertical linear selection module or a horizontal selection module. The modules employed can be used to simulate forces as a function of the shift and selection position in a manner that is representative of a gearbox.
