Abstract

The invention discloses a high-reliability electronic gear shifter core structure. The high-reliability electronic gear shifter core structure comprises a support, a side plate, a tooth-shaped plate and a gear shifting assembly; the gear shifting assembly comprises a left gear shifting block, a gear shifting rod, a right gear shifting block, a steel ball, a locking plate, a locking spring, a gear spring and a sleeve; and the gear shifting rod is clamped and fixed through the left gear shifting block and the right gear shifting block, a cylindrical boss of the left gear shifting block is in close fit with an inner round hole of a large bearing, a pin shaft hole of the right gear shifting block is in close fit with a pin shaft, and the pin shaft is in close fit with an inner round hole of a small bearing. The locking spring and the locking piece slide in inner cavities of the left gear shifting block and the right gear shifting block, the steel ball and the gear spring move in an inner circular hole of the sleeve and are in sliding connection with the tooth-shaped plate, and an unlocking rod slides in the gear shifting rod. The gear shifting operation hand feeling is enhanced, the service life of a gear shifter is prolonged, the use strength and the structural reliability of the gear shifter are improved, and the misoperation risk is avoided through the locking function.

Description

technical field [0001] The invention relates to the technical field of automobile gear shifters, in particular to a core device of a high-reliability electronic gear shifter. Background technique [0002] With the upgrading of gearboxes, electronic shifters are becoming more and more popular. Among them, the demand for civil and military engineering vehicles, such as coal mine trucks, muck trucks, dock unloading trucks and military special transport vehicles, is rising rapidly. Since engineering vehicles need to switch gears frequently, and the operating environment is relatively harsh, and the electronic shifter generally used in passenger cars has a life span of 200,000 shifts, and the static strength requirement is less than or equal to 300N, so it is necessary to design an electronic shifter that can High-life and high-strength electronic shifters that meet harsh environments. Contents of the invention [0003] In order to solve the technical problem that the function...
