Separating retention mechanism of axial auto-controlled clutch

Abstract

The invention provides a separation maintaining mechanism, which is suitable for all spring pressing type axial auto-regulated clutches and consists of a catch ring, a subsidiary catch ring and a subsidiary spacing ring, wherein an axial stop joggling mechanism consists of the catch ring and the subsidiary catch ring so as to maintain a separating state for a serviced work engaging mechanism; and a spacing jogging mechanism consists of the catch ring and the subsidiary spacing ring so as to maintain the stability of stop relation of the stop jogging mechanism. The separation maintaining mechanism is characterized in that the spacing jogging mechanism and the stop jogging mechanism are rigidly integrated or circumferentially fixed; the stop jogging mechanism is axially positioned in the work engaging mechanism, and is radially positioned inside or outside the work engaging mechanism; and lift angles forming both stop working faces of the stop jogging mechanism and the spacing jogging mechanism are enough to ensure friction self-locking and stop working condition when the two mechanisms are contacted, so that the separation maintaining mechanism is capable of self-adapting separation shaft distance variation and automatically compensating abrasion, and maintains slipping mode of zero-collision of all components in stop working condition for a long time, and separation stop of the separation maintaining mechanism and absolute reliability of jogging reset process.

Description

technical field [0001] The invention relates to an axial pressing type self-control clutch in the field of mechanical transmission, in particular to a holding mechanism for maintaining the separated state of a spring pressing type self-control clutch after axial separation, belonging to the field of mechanical transmission. technical background [0002] The axial spring compression type self-control clutches in the prior art, except the jaw type self-locking differential, the jaw type overrunning clutch and safety clutch, and the spring steel ball type safety clutch do not have the state maintenance function after axial separation . After the driving and driven coupling elements are axially separated, the relative rotation of the two will bring impact, collision, noise and excessive wear of the end face teeth, and the jaw type safety clutch with a large axial elastic coupling force will even be severe enough to break The extent of the face teeth. Therefore, whether in theo...

Problems solved by technology

Therefore, their applications are greatly restricted, making it difficult to take advantage of their advantages such as huge transferable torque, simple structure, and no slippage and heat generation after engagement.

Although it has the technology of the separation and holding mechanism in the jaw-type self-locking differential, due to the special layout of the mechanism with the help of its active ring, it puts forward too strict requirements on the compression spring stiffness, spring length, and assembly. And affected by limiting factors such as the inability to adjust the spring pressure and the inability to compensate for wear, this technology has not been extended to other related clutches so far.
