Embodiment Construction
[0026] Some possible implementations of the present application are described below with reference to the accompanying drawings.
[0027] figure 1 Shown is a selector device for a vehicle gearbox according to an embodiment of the present application, for driving a selectively coupling element for a select shift operation in a vehicle gearbox. The "selective combination element used for shifting operation" mentioned here refers to selectively combining or disengaging with a certain power transmission element (such as gear, etc.) according to the expected demand, or selectively combining with two or One or some of the more power transmission elements are combined with or disengaged from these power transmission elements. The most common selectively coupled element used in a vehicle gearbox for shifting operations is a synchronizer, but as an alternative or in addition, it can include sliding gears, sliding sleeves, clutches, joysticks, etc. Movement, etc.) to realize the combi...

The invention relates to a gear selecting and shifting device used for a vehicle gearbox. The gear selecting and shifting device comprises a gear-shifting finger assembly, the gear-shifting finger assembly comprises a plurality of gear-shifting fingers distributed in the axial direction, at least one of the gear-shifting fingers is a long gear-shifting finger, and others are short gear-shifting fingers; the gear selecting and shifting device also comprises a plurality of discs distributed in the axial direction, each disc is associated with a selective combination element in the gearbox, and is configured in a way that under the action of the gear-shifting fingers, the position of each disc can be switched among the middle position, the left transverse position and the right transverse position; the gear-shifting finger assembly is configured in a way that the gear-shifting finger assembly can move in the axial direction and rotate around the central axis in order to make at least one gear-shifting finger act on the corresponding disc; when the long gear-shifting finger acts on the disc, the disc can be moved to or locked on the left transverse position or the right transverse position; when one short gear-shifting finger acts on one corresponding disc, the disc can be moved to or locked on the middle position; at least one of the plurality of discs is a wide disc, others are narrow discs, and the thickness of the wide disc is configured in a way that the same gear-shifting finger can act on the wide disc on at least two axial positions, of the gear-shifting finger assembly, which are separated from each other.
Description
technical field [0001] The present application relates to a gear selector for a vehicle gearbox. Background technique [0002] Synchronizers are usually used in vehicle gearboxes to achieve gear access and switching. Selecting and shifting is relatively simple when only one synchronizer is controlled, but if more than two synchronizers need to be controlled, more complex operations need to be implemented. [0003] For example, if multiple synchronizers need to be moved for one shift operation, it is necessary to select the first synchronizer first, then perform the shift of the first synchronizer, then select the second synchronizer, and perform the second synchronizer shift. first synchronizer shift, then select gear to the third synchronizer, carry out the third synchronizer shift, and so on. In this way, the number of actions that need to be completed is twice the number of synchronizers that need to be moved, the control is complicated and a long shift time is required...
