Abstract

The invention belongs to the technical field of transmission devices, and particularly relates to a gear shifting mechanism and a two-gear transmission device. The gear shifting mechanism comprises a first component, a second component, a third component and a sliding piece arranged on the first component, and an elastic piece is arranged between the first component and the sliding piece. The first inner friction unit is arranged on the sliding piece, the first outer friction unit is arranged on the second component, the second inner friction unit is arranged on the first component, and the second outer friction unit is arranged on the third component. The execution mechanism controls the first component to reciprocate along the center line so that the first inner friction unit and the first outer friction unit can be connected or separated, and meanwhile the second inner friction unit and the second outer friction unit can be connected or separated. The gear shifting mechanism is simple in structure, low in control precision requirement and capable of achieving smooth gear shifting and uninterrupted power when being used for a two-gear transmission device.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a shifting mechanism and a two-speed transmission device. Background technique [0002] The traditional two-speed transmission mechanism requires two clutches to work together. Since the clutch includes a control oil circuit and a control system, the two clutches require two independent oil circuits and two control systems, which makes the structure of the existing transmission mechanism more complicated. Complex, such as the dual-clutch transmission mechanism disclosed in China's authorized invention patents (CN109661526B, CN110914563B). In the shifting process, in order to ensure the continuous and stable transmission of power, it is necessary to quickly engage the other clutch while the other clutch is disengaged; if the two clutches are disengaged at the same time, the power will be interrupted, and there will be serious equipment defects. Therefore, in addition...
