A controllable manual two-way overrunning clutch, including a clutch lever, a drive shaft, a fixed connection plate, a clutch claw, a claw plate, an output connection plate and rollers, the drive shaft has an axial central through hole, and the middle part of the drive shaft passes through the bearing Installed in the inner hole of the fixed connection plate, a groove is provided at the left end of the fixed connection plate, the output connection plate is installed in the groove through the bearing provided on it, and the left end of the drive shaft is installed on the output connection plate through the bearing In the inner hole of the claw plate, the claw plate is set on the drive shaft through a bearing sleeve, and the claw plate is located in the inner hole of the output connection plate. The left and right sides of the outer surface of the claw plate are respectively provided with roller installation grooves. There are rollers installed inside, the inner side of the roller is in contact with the outer surface of the drive shaft, and the outer side of the roller is in contact with the inner peripheral surface of the output connection disc; the upper and lower sides of the inner surface of the claw disc are symmetrically provided with card slots, and the drive shaft A clutch lever is pierced through the central through hole. One end of the clutch lever extends out of the drive shaft and is fixedly connected with a clutch claw. The drive shaft drives the claw disc to rotate.

Further, the drive shaft is connected to the clutch lever through a key.

Due to the above-mentioned technical scheme, the utility model has the following advantages:

When the utility model is used in practice, if the clutch claw is snapped into the slot on the claw plate through the clutch lever, the claw plate can be driven to rotate through the drive shaft and the clutch lever, and then the output connection plate can be rotated through the roller. When the clutch pawl is separated from the pawl plate, the drive shaft and the output connection plate rotate independently without affecting each other; the utility model controls the relative positional relationship between the clutch pawl and the pawl plate manually, the structure is simple and ingenious, manual operation is convenient, and the realization of In order to diversify the functions, it has the functions of two-way transmission of torque and two-way idling.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is A-A sectional view of Fig. 1;

In the figure: clutch lever 1, drive shaft 2, fixed connecting disc 3, clutch claw 4, claw disc 5, output connecting disc 6, roller 7.

Detailed ways

The technical solutions of the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 and 2, a controllable manual two-way overrunning clutch includes a clutch lever 1, a drive shaft 2, a fixed connection plate 3, a clutch pawl 4, a claw plate 5, an output connection plate 6 and a roller 7. The shaft 2 has an axial central through hole, and the middle part of the drive shaft 2 is installed in the inner hole of the fixed connection plate 3 through a bearing, and a groove is arranged on the left end of the fixed connection plate 3, and the output connection plate 6 passes through it. The bearing is installed in the groove, the left end of the drive shaft 2 is installed in the inner hole of the output connection plate 6 through the bearing, the claw plate 5 is sleeved on the drive shaft 2 through the bearing, and the claw plate 5 is located on the output connection plate 6 In the inner hole, the left and right sides of the outer surface of the claw plate 5 are respectively provided with roller installation grooves, and rollers 7 are installed in the roller installation grooves. The inner side of the rollers 7 is in contact with the outer surface of the drive shaft 2, and the rollers The outer side of 7 is in contact with the inner peripheral surface of the output connection disc 6; the upper and lower sides of the inner surface of the claw disc 5 are symmetrically provided with draw-in grooves, and a clutch lever 1 is pierced in the central through hole of the drive shaft 2, and one end of the clutch lever 1 After the part stretches out from the drive shaft 2, it is fixedly connected with a clutch pawl 4, and the upper and lower ends of the clutch pawl 4 correspond to the draw-in groove, and the drive shaft 2 drives the pawl disc 5 to rotate by the engagement of the clutch claw 4 and the draw-in groove.

The drive shaft 2 is connected with the clutch lever 1 through a key.

When the utility model is used in practice, if the clutch claw is snapped into the slot on the claw plate through the clutch lever, the claw plate can be driven to rotate through the drive shaft and the clutch lever, and then the output connection plate can be rotated through the roller. When the clutch pawl is separated from the pawl plate, the drive shaft and the output connection plate rotate independently without affecting each other; the utility model controls the relative positional relationship between the clutch pawl and the pawl plate manually, the structure is simple and ingenious, manual operation is convenient, and the realization of In order to diversify the functions, it has the functions of two-way transmission of torque and two-way idling.
