Description of drawings
Fig. 1 is the decomposition texture scheme drawing of the utility model band buffering free-wheel clutch one preferred embodiment.
Among the figure, relevant Reference numeral is as follows:
The 1-motor output shaft, the 2-ratchet, the 3-spring, the 4-bearing, the 5-wheel hub, the 6-bearing,
The 7-recoil spring, the 8-one-way damper, the 9-jump ring, the 10-bearing, the 11-buffer cover,
The 12-disc brake, 13-tightening screw, 14-motor.
The specific embodiment
Below in conjunction with accompanying drawing, band buffering free-wheel clutch of the present utility model is elaborated by specific embodiment.
Referring to Fig. 1, the band buffering free-wheel clutch in the present embodiment comprises:
Four ratchets 2, as arrow indication among Fig. 1, be installed on the motor output shaft 1 in the corresponding pawl slot, spring 3 is installed in the groove position on the motor output shaft 1, one end and the motor output shaft 1 of four ratchets 2 is fixing, and the other end of ratchet 2 opens under the situation that is not subjected to external force along clockwise direction;
Bearing 6 is arranged at a side of wheel hub 5, and its upper edge circumferentially is distributed with 3 blocks 61;
Three-jaw ratchet 8 is set on motor output shaft 1, the ratchet 2, and its axis hole wall is provided with unidirectional tooth, the direction of this unidirectional tooth and ratchet 2 to open direction consistent; Its outer wall is provided with 3 dogs 81 that extend along same direction, is provided with recoil spring 7 between described dog 81 and the block 61, and an end of recoil spring 7 contacts with dog 81, and the other end contacts with block 61.
Buffer cover 11 is inserted on the bearing 6, and the attaching parts of buffer cover 11 ends cooperates with corresponding link slot on the bearing, thereby covers recoil spring 7 and three-jaw ratchet 8; The screw hole that holding screw 13 passes the screw hole of disc brake 12 and passes buffer cover 11 is fastened on buffer cover 11, disc brake 12 on the bearing 6.Drive three-jaw ratchets 8 by ratchet 2 during motor output shaft 1 rotation, three-jaw ratchet 8 drives recoil springs 7, and recoil spring 7 drives bearings 6, realizes that takeoff output with motor is to wheel hub 5 thereby bearing 6 drives wheel hubs 5.
Owing to be provided with unidirectional tooth in the axis hole of three-jaw ratchet 8, when motor stopped outputting power, three-jaw ratchet 8 was because inertia still keeps rotation, also was that wheel hub 5 keeps rotation and motor stops operating, thereby make unidirectional tooth and ratchet break away from bonding state, the realization wheel hub separates with motor.
In the present embodiment, because the rotating speed of wheel hub 5 is zero during motor output shaft 1 beginning outputting power, motor output shaft 1 must have impulsive force to three-jaw ratchet 8, wheel hub 5, and recoil spring 7 freely is disposed across on the three-jaw ratchet 8 on the dog and bearing 6 between the link stopper, can play the effect of buffering.
Simultaneously, recoil spring 7 also has the flexible effect that three-jaw ratchet 8 is installed, and makes that one-way damper can be done small size rotation, can find the center automatically accurately when installing, and installs simple.
Referring to Fig. 1, the mechanical speed change electric wheel hub that the utility model provides comprises motor 14, wheel hub 5 and aforesaid band buffering free-wheel clutch, and the aforementioned band buffering of concrete structure free-wheel clutch all illustrates, repeats no more herein.
In the present embodiment; only describe with ratchet-Ratcheting one-way clutch; but protection domain of the present utility model is not limited to this; as long as the outer ring or the inner ring of free-wheel clutch are provided with buffer gear; just belong to the scope of the utility model protection, for example free wheeling roller chutch, free wheeling sprag clutch etc. all can be realized.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with the determined scope of claim.For those skilled in the art, in not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
