Abstract

A dual-drive forward and reverse gearbox comprises a box body, a main power shaft assembly, two output shaft assemblies arranged in pairs, a straight driven shaft assembly, a steering driven shaft assembly, a dual-hydraulic driver, a straight transmission mechanism, a steering transmission mechanism, a sun wheel assembly and two planetary differential assemblies arranged in pairs. A hydraulic control system and a mechanical transmission system are separately designed and are respectively arranged outside and inside a box body, so that the structure of the gearbox is simplified, faults are convenient to find and maintain, and a straight transmission mechanism and a steering transmission mechanism are separately arranged, so that the faults are convenient to find and maintain; the output shafts on the two sides of the box body are designed to rotate positively and negatively, the steering required radius is reduced, the pivot steering purpose is achieved, and operation on narrow terrains is facilitated; the planetary differential structure is applied, so that the adaptability of the gearbox to complex terrains is improved, and the power is improved.

Description

technical field [0001] The invention relates to the fields of vehicle walking, steering and speed change, in particular to a dual-drive forward and reverse gearbox. Background technique [0002] The steering of agricultural machinery is generally to adjust the speed of the driving wheels on both sides of the gearbox, and achieve the purpose of steering through the speed difference. Alternatively, a hydraulic drive is used to drive the forward and reverse gearbox, and through the drive of the internal hydraulic control system of the gearbox, the output shafts on both sides of the gearbox can be turned forward and reverse to achieve steering. [0003] Refer to the existing technical scheme of the patent titled "Electro-hydraulic Control Gearbox for Wheeled Traveling Machinery" and the patent number ZL201720927493.2. It can be seen that when designing a hydraulically driven forward and reverse gearbox, the hydraulic control is often used The combination of the system and the m...
