Clutch mechanism with advance buffering and safe back off function

Abstract

The present invention relates to one kind of clutch mechanism with advance buffering and back safety functions. The clutch mechanism has one first spindle with one mating toothed surface towards the second spindle, one second spindle with one clutch sleeve, one shifting fork for controlling the axial displacement of the clutch sleeve, one clutch socket ring on the clutch sleeve, and one buffer mechanism between the clutch socket ring and the clutch sleeve and including at least one advance mesh buffering spring and at least one back reset safety spring for correct meshing and safe separation. The present invention has raised safety performance.

Description

technical field [0001] The invention relates to a clutch mechanism which is widely applicable to shaft transmission and has forward buffering and safe backward functions. Background technique [0002] Existing clutch mechanism designs for shaft transmission in general vehicles, such as: U.S. Patent No. 5,997,428 relates to the power switching clutch design of two-wheel transmission and four-wheel transmission. [0003] This prior art document discloses a clutch design mechanism for power transmission between two rotating shafts, which uses a shift fork sleeve disposed between opposite ends of the two rotating shafts to generate a clutch for power transmission between the two rotating shafts. [0004] In these designs, when the displacement of the shift fork sleeve spans between the two rotating shafts to generate a power transmission connection, the displacement of the shifting fork sleeve on one rotating shaft intends to engage and the other rotating shaft is instantly enga...

Problems solved by technology

[0004] In these designs, when the displacement of the shift fork sleeve spans between the two rotating shafts to generate a power transmission connection, the displacement of the shifting fork sleeve on one rotating shaft intends to engage and the other rotating shaft is instantly engaged and not aligned. Due to the design technology and space type factors, the components are complicated and the space occupied is short, so the external space of the machine tool is used to set up the relevant buffer mechanism separately. Not only the structure is complex, the volume is large, the cost is high, but also the assembly process is time-consuming and labor-intensive. , does not meet the utilization of industrial demands and the efficiency of economic demands

[0005] Therefore, the inventor of the present invention has developed a clutch mechanism with a buffer function for the above-mentioned problems, and applied for a Chinese patent, the application number is 200610057290.9, and the title of the invention is "clutch structure with a buffer function", but in the design of the above application, there is There are many components and the design volume is relatively large. Although the application has certain functionality and industrial applicability, based on the principle of continuous improvement in technological creation and the pursuit of continuous improvement in product quality, the reduction of components, cost reduction and size, there is indeed a need for further research and innovation
