Manual gear selecting and shifting mechanism used for automated manual transmission (AMT) testing

Abstract

The invention discloses a manual gear selecting and shifting mechanism used for automated manual transmission (AMT) testing, and relates to the technical field of testing of gear selecting and shifting. A gear shifting structure includes a steering base, a lever center piece, a universal ball auxiliary mounting seat, an upper universal ball seat and an operating lever, wherein the steering base isinstalled in a lower mounting seat, the lever center piece is rotationally connected onto the steering base, the universal ball auxiliary mounting seat is arranged at the top part of the lever centerpiece and is provided with a lower universal ball seat, the upper universal ball seat is installed on a top plate of the lower mounting seat, and the operating lever is arranged to penetrate throughthe lever center piece, the universal ball auxiliary mounting seat, the lower universal ball seat, the lower mounting seat, the upper universal ball seat and a gear shifting groove in sequence from bottom to top. The manual gear selecting and shifting mechanism is equipped with the gear shifting structure; the lever center piece of the gear shifting structure is in location fit with a gear selecting and shifting shaft; an operator can transmit power through the lever center piece under limiting of the gear shifting groove, the upper universal ball seat, the lower universal ball seat and the steering base by driving the operating lever with one hand to accurately perform gear selecting and shifting operations, so that the work efficiency of the operator is greatly increased, and the work intensity and danger of the operator are reduced.

Description

technical field [0001] The invention relates to the technical field of test gear shifting, in particular to a manual gear shifting mechanism used for gear shifting when an AMT gearbox is tested on a test bench. Background technique [0002] The automatic (AMT) transmission is a transmission device that can automatically shift gears according to the vehicle speed and engine speed relative to the manual transmission. The selector shaft is the actuator for the AMT transmission to shift gears , is also the core component for the realization of the variable speed function. In the assembly stage of the automobile gearbox assembly, the shifting mechanism is only finally configured in the vehicle production, but the shifting mechanism in the final configuration is not suitable for the shifting operation in the testing stage. [0003] When the AMT gearbox test is actually carried out on the test bench, two staff members are required to cooperate to select and shift gears through sim...
