The invention provides a gear selecting and shifting execution mechanism of an automatic transmission of a wide vehicle. The gear selecting and shifting execution mechanism of the automatic transmission of the wide vehicle comprises a gear shifting motor and a gear selecting motor, wherein the gear shifting motor is connected with a first worm gear through a first worm, a center hole of the first worm gear is connected with a gear shifting control shaft, the gear selecting motor is connected with a second worm gear through a second worm, a center hole of the second worm gear is connected with a gear selecting control shaft, the other end of the gear shifting control shaft is connected with a sliding block, a shifting head is arranged on the sliding block, the gear shifting control shaft drives the shifting head to rotate through the sliding block, a guide rail is arranged in the sliding block, the other end of the gear selecting control shaft is connected to a ball in the guide rail and drives the ball to rotate, and the ball drives the shifting head to move horizontally through the guide rail. The gear selecting and shifting execution mechanism of the automatic transmission of the wide vehicle has the advantages that when an AMT fails, an original gear shifting handle can be installed directly so that a manual mode can be achieved through switching, the integration level of the mechanism is high, dismantling is convenient, the control precision is high, the power interruption time is short, the comfort level is high, and the failure rate is low.
Description
technical field [0001] The invention relates to the technical field of vehicle transmission control mechanisms, in particular to a wide-body vehicle automatic transmission gear selection and shifting actuator. Background technique [0002] In recent years, my country's national economy has developed rapidly, energy demand has increased day by day, and mining tasks in mining areas have increased year by year. Wide-body dump trucks have emerged to improve the operating efficiency of mining areas, reduce mining operating costs, and increase profit margins. [0003] Currently on the market, there are mainly two types of transmission configurations for wide-body dump trucks used in mining areas: manual transmission and automatic transmission. However, for the special working conditions in the mining area, frequent high-intensity operations put forward higher requirements on vehicle performance, and the shortcomings of traditional manual transmissions are also manifested, mainly r...
