Detailed Description
The following specific embodiments of the utility model are described in order to provide those skilled in the art with an understanding of the present disclosure. The utility model may be embodied in other different forms, i.e., modified and changed without departing from the scope of the utility model.
Examples: the double-chain wheel motor system on the same side comprises a motor 1, a common chain wheel 2 and a one-way chain wheel 4, wherein the common chain wheel and the one-way chain wheel are positioned on the same side of the motor, the common chain wheel is sleeved on an output shaft of the motor and is fixedly connected with a shell of the motor, and the center position of the one-way chain wheel is sleeved on the output shaft of the motor and is connected with the shell of the motor (fixedly connected with the output shaft of the motor);
the common sprocket is driven to rotate by the rotation of the motor, and the outer ring 41 of the unidirectional sprocket does not rotate; the outer ring of the unidirectional sprocket wheel rotates to drive the inner ring 42 of the unidirectional wheel to rotate so as to drive the common sprocket wheel and the motor shell to synchronously rotate.
The unidirectional sprocket is in threaded connection with the housing of the motor. However, the present utility model is not limited to this, and other means may be used as long as the center position of the one-way sprocket can be fixed to the housing of the motor.
The motor shell is provided with a threaded hole 11, the common sprocket is also provided with the threaded hole 11, and the common sprocket is fixed on the motor shell through the screw 3 penetrating through the threaded hole. However, the present utility model is not limited thereto, and a common sprocket can be attached and fixed to a housing of a motor by other structures.
The unidirectional sprocket comprises an inner ring and an outer ring, wherein the inner ring is fixedly connected with a shell of the motor, and the inner ring is in unidirectional transmission connection with the outer ring through a unidirectional structure.
The unidirectional structure is a ratchet structure. Namely, the rotation of the outer ring can drive the rotation of the inner ring, but the rotation of the inner ring can not drive the rotation of the outer ring. The working principle of the ratchet structure and the unidirectional chain wheel is the prior art, so the description is omitted.
The name of the ordinary sprocket in this embodiment is to distinguish it from the unidirectional sprocket, which is an ordinary sprocket that can rotate in both directions.
The motor system is used for an electric tricycle or an electric two-wheel vehicle. Because the electric tricycle has more installation space, the motor system is convenient to install, so the motor system is more feasible when being used for the electric tricycle; of course, the motor system is also applicable to the situation that the installation space is enough by the structural modification of the electric bicycle.
The working principle and the working process of the utility model are as follows:
as shown in fig. 5, the first chain 10 is simultaneously sleeved on the outer ring of the unidirectional sprocket and the wheel disc 20 at the pedal, and the second chain 30 is simultaneously sleeved on the common sprocket and the speed changing flywheel 40, which is mounted at the rear wheel.
There are two driving modes, the first: as shown in fig. 3, a indicates the rotation direction of the housing of the motor, B indicates the rotation direction of the normal sprocket, C indicates that the unidirectional sprocket is not rotatable, a person does not step on the foot, only the motor works, because the output shaft of the motor is fixed and not rotated, and thus the housing of the motor rotates when the motor works, and because the housing of the motor is fixedly connected with the normal sprocket, the normal sprocket can synchronously rotate, and meanwhile, because a unidirectional structure is arranged between the inner ring and the outer ring of the unidirectional sprocket, the outer ring does not rotate, and the speed change of the electric vehicle is realized through the speed change flywheel.
Second kind: as shown in fig. 4, a represents the rotation direction of the shell of the motor, B represents the rotation direction of the common sprocket, C represents the rotation direction of the unidirectional sprocket, a person steps on a pedal, a wheel disc at the pedal rotates, the outer ring of the unidirectional sprocket rotates through the transmission of the first chain, and the inner ring also rotates due to the unidirectional structure, so that the common sprocket and the shell of the motor also rotate, and the second chain drives the speed changing flywheel and the rear wheel to rotate, so that the speed change of the electric vehicle is realized through the speed changing flywheel in the state;
under the condition that the driver does not want to pedal or is inconvenient to pedal, the driver can drive the wheels by pure electric power (namely the first driving mode) to drive the vehicle to advance;
under the condition that the vehicle needs to be driven for a longer time or body building is needed, a hybrid power mode driven by manpower and a motor (namely a second driving mode) can be adopted to drive the vehicle to advance;
the two-stage transmission can be realized through the two modes, namely, the speed ratio transmission is changed, and the two-stage transmission is wider in practical application; in addition, the gear box is matched with the speed changing flywheel, so that transmission with more speed ratios can be realized, and more choices and requirements of users are met.
The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures made by the description of the utility model and the accompanying drawings, or direct or indirect application in other related technical fields, are included in the scope of the utility model.
