Embodiment Construction
[0009] The present invention will be further described below in conjunction with accompanying drawing:
[0010] Depend on figure 1 and figure 2 combine image 3 , Figure 4 As shown, a two-way overrunning clutch reversing control mechanism includes a reversing rod 1, an inner star wheel 2, a roller 5, and an outer ring 6. The inner star wheel 2 is integrated with the output shaft as a power output component, and the outer ring 6 is The power input part, the reversing rod 1 can slide left and right in the shaft hole of the inner star wheel 2, there are two slopes 12 in the middle of the reversing rod 1, and each slope 12 has a ring groove at the left and right ends, which are respectively large and small. The end ring grooves (10, 11) have a hole 13 on the left and right sides of the inner star wheel 2. There is a push rod 3 inside the hole 13. The push rod 3 and the hole 13 are in a sliding fit and can slide freely up and down in it. , and the position of the hole 13 corr...

The invention provides a reversing control mechanism of a bidirectional overrunning clutch, which mainly solves the problems that the prior overrunning clutch needs to reverse after stoppage and has acomplicated structure and poor working sensitivity. The reversing control mechanism is characterized in that the middle of a reversing rod (1) is provided with two bevels (12); two ends of the bevelare respectively provided with annular grooves (10, 11); two sides of an inner star wheel is radially provided with holes (13); the inside of each hole (13) is provided with a push rod (3) which is insliding fit with the hole; the inner star wheel is of a regular hexagon; the inside of an arched space formed between the inner star wheel and an outer ring (6) is provided with a roller (5); the roller (5) is connected with reversing rings (4) sleeved on two sides of the inner star wheel (2) through a shifting fork (9); the surface of an inner hole of the reversing ring (4) is provided with a groove (14); the bottom of the groove is a bevel; and a pin roll (8) arranged on the inner star wheel (2) is connected with the reversing ring (4) through a spring (7). The reversing control mechanism has the characteristics of simple structure, high reliability and sensitivity and reversibility in operation.
Description
Technical field: [0001] The invention relates to a clutch control mechanism, in particular to a two-way overrunning clutch reversing control mechanism. Background technique: [0002] Overrunning clutch is widely used in one-way power output and backstop output in mechanical transmission. For example, the pulsating continuously variable transmission manufactured by using overrunning clutch technology has been widely used in textile, food machinery, etc., and has been widely used in the field of mechanical transmission. . The overrunning clutch is already a relatively mature technology in the one-way transmission of small torque. It mainly adopts friction self-locking mechanism. The typical structure is block type and roller type. However, in practical applications, there are many mechanical requirements. The direction of rotation is changing, so there is a two-way overrunning clutch. Most of the existing two-way overrunning clutch reversing control mechanisms need to be reve...
