Gear-shifting device of flexible-shaft type gearbox test table

Abstract

The invention discloses a gear-shifting device of a flexible-shaft type gearbox test table. The gear-shifting device comprises an electrical cabinet, an electric sliding table used for gear selection, an electric sliding table used for gear shifting, a mechanical arm, a slide block, a rocker arm, a universal joint, flexible shafts and a supporting base. The electric sliding table used for gear selection and the electric sliding table used for gear shifting are vertically installed in a right-angle intersection way. The electric sliding table used for gear selection is transversely fixed at the top part of the electricalcabinet via a screw. The electric sliding table used for gear shifting is longitudinally fixed on the nut base of the electric sliding table used for gear selection via the screw. The bottom part of the mechanical arm is fixed on the nut base of the electric sliding table used for gear shifting via the screw. The side shaft of the slide block is hinged with the front end of the mechanical arm. The top part of the rocker arm is slidably connected with the slide block. The rocker arm is fixed at the top part of the universal joint via the screw. The universal joint is fixed at the top part of the supporting base via the screw. The internal core head parts of the flexible shafts are fixed on the bottom panel of the rocker arm. The pipe walls of the flexible shafts are fixed on the panel of the supporting base. The control objects of the gear-shifting device are the flexible shafts, and the structure is simple, operation is stable, installation is convenient and generality is high.

Description

technical field [0001] The invention belongs to the technical field of vehicle testing devices, and in particular relates to a shifting device of a flexible shaft type gearbox testing bench. Background technique [0002] In some cars, medium and large passenger cars and trucks, because the general arrangement requires a long distance between the driver's position and the gearbox, a flexible shaft control mechanism is often used for long-distance gearbox shifting operation, which has a simple structure, easy operation and high transmission efficiency. . [0003] In the transmission test, powertrain test or vehicle test, it is necessary to continuously change the gear of the vehicle during the test. If manual shifting is used, it is necessary to stop the vehicle after completing the test of one gear, and the dynamic test process of continuous shifting cannot be completed. Therefore, a shifting device is required to replace manual automatic shifting. At present, the objects c...
