Abstract

The invention belongs to the technical field of transmissions, and specifically includes a shifting mechanism and a two-speed transmission. Wherein, the shifting mechanism includes an actuator, a first component, a second component, a third component, and a sliding member arranged on the first component, and an elastic member is arranged between the first component and the sliding member; the shifting mechanism further includes The first internal friction unit and the second internal friction unit arranged on the first component, the regulating component, the first external friction unit and the positioning part arranged on the second component, the second external friction unit arranged on the third component ; Drive the regulating member to reciprocate along the center line by the actuator to realize the engagement or separation of the first inner friction unit and the first outer friction unit while the second inner friction unit and the second outer friction unit are separated or engaged. The shifting mechanism has a simple structure, low requirements for control accuracy, small radial size, and is convenient for selecting a friction unit; when used in a two-speed transmission device, it can achieve smooth shifting and uninterrupted power.

Description

technical field [0001] The invention relates to the technical field of transmissions, in particular to a shifting mechanism and a two-speed transmission. Background technique [0002] The traditional two-speed transmission 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. , 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 to the complex structure of th...
