Description
Technical field
The present invention relates to a kind of driven off by shaft clutch mechanism that is widely used in advance buffering and safe fallback function.
Background technique
Existing general vehicle designs with driven off by shaft clutch mechanism, as No. the 5th, 997,428: U.S.'s patent of invention about the two powershift clutches designs of taking turns transmission and four-wheel transmission.
Disclose powerdriven clutch design organization between a kind of two rotating shafts in the prior art document, utilize the clutch that the set shift fork sleeve that is subjected to displacement produces transmission of power between two rotating shafts between two rotating shaft opposite ends.
And when in these designs, producing transmission of power and connect about shift fork sleeve displacement cross-over connection desire between two rotating shafts, for the shift fork sleeve by the rotating shaft top offset solution that another rotating shaft moment meshes not contraposition problem of desiring to be engaged and linked, because of the factor of designing technique and space kenel causes spare part complexity and occupy-place shortcoming, so all utilize the facility space outerpace that relevant damping mechanism is set separately, not only complex structure, volume is big, cost is high, and yet more time-consuming the taking a lot of work of assembling processing, and do not meet the usability of industry demand and the benefit of economic demand.
Therefore the present inventor once developed the clutch mechanism with pooling feature at the problems referred to above, and application Chinese patent, application number is 200610057290.9, denomination of invention is " clutch structure with pooling feature ", but in the design of above-mentioned application, the spare part that is had is more and to be set as volume also bigger, though this application has certain functional and industry applications, but the pursuit that principle that constantly progresses greatly based on technological innovation and product mass-energy constantly promote, reduce spare part, reduction cost and volume, truly have it to research and develop necessity of innovation again.
Summary of the invention
The present invention discloses a kind of " clutch mechanism with advance buffering and safe fallback function "; its feature is: the mesh tooth face that the second axle direction on one day is set on the axis body of clutch mechanism first axle; but establish a location engagement and the clutch sleeve of axial displacement on second spindle shaft on the leading portion axis body of second axle; clutch sleeve on this second spindle shaft is subjected to a fork controls axial displacement; and in a sheathed location engagement on the clutch sleeve and the clutch collar that can axial displacement on clutch sleeve; be provided with damping mechanism in clutch sleeve and clutch cover interannular; this damping mechanism comprises at least one or more than one a plurality of engagement damping spring and at least one or more than one a plurality of safety spring that resets that retreats of advancing; make clutch sleeve advanced by the shift fork interlock axial displacement generation clutch collar and mesh the first axle mesh tooth face; if each other during non-correct engagement contraposition; the engagement damping spring produces buffering by advancing; treat that both mesh contraposition moment; before push away the down that the trap ring reaches the clutch collar and the first axle mesh tooth face immediately by the engagement damping spring that advances and close interlock; on the contrary; when retreating, shift fork make clutch sleeve return original position when producing the clutch collar in advance and breaking away from the first axle mesh tooth face; if the clutch collar can't retreat disengaging for some reason; pull back the strength that resets of moving back by retreating the safety spring generation that resets; the clutch collar can be pulled back immediately move back and reach the effect that automatic disengaging resets, and then the security effectiveness of effectively protecting the clutch mechanism spare part to advance and be engaged and linked and retreat disengaging.
The object of the invention is:
1, provides the clutch mechanism that a structure is simplified, cost is low with buffering and Safety function.
2, provide the clutch mechanism that a volume is little, installation is easy to have buffering and Safety function.
