Manual-transmission testing device

Abstract

The invention provides a manual-transmission testing device capable of controlling the swing angle of a shift lever and acquiring signals of dragline travel distance and shift-lever handfeel at the angle. The manual-transmission testing device comprises a control unit, a manual-transmission mounting seat (1), a first swing mechanism, a second swing mechanism and a stay wire sensor (3). A first electric cylinder (6) is used for driving a first supporting piece (5) to swing around a first rotating shaft (4), and the first rotating shaft (4) is connected with a first rotating sensor (7). A second electric cylinder (10) is used for driving a second supporting piece (9) to swing around a second rotating shaft (8), and the second rotating shaft (8) is connected with a second rotating sensor (11). The second supporting piece (9) is provided with a manipulator used for fixing a gear-shifting handle (12) of a manual transmission (2). The manipulator is provided with a force sensor (14). The first rotating shaft (4) is perpendicular to the second rotating shaft (8). The stay wire sensor (3) is electrically connected with the control unit.

Description

technical field [0001] The invention relates to the technical field of manual transmission assembly lines, in particular to a manual transmission testing device. Background technique [0002] After the manual transmission shift lever and shift rocker assembly are assembled, it is necessary to shake the shift lever to detect whether the assembly of the shift lever and the shift rocker assembly meets the requirements. For example, the Chinese patent application with publication number CN102297763A, although it discloses A rough test idea, but the specific structure has not been implemented. There is no substantive content in how to control the angle of the shaking shift lever, the stroke of the cable, and the signal acquisition structure of the feel force of the shift lever. Therefore, a design that can control the shaking shift The angle of the lever, the manual transmission test setup at which the signal of the travel of the cable and the feel force of the shift lever is obt...

There is no substantive content in how to control the angle of the shaking shift lever, the stroke of the cable, and the signal acquisition structure of the feel force of the shift lever. Therefore, a design that can control the shaking shift The angle of the lever, at which angle the signal of the stroke of the cable and the signal of the feel force of the shift lever is a manual transmission test device is an important topic
