Abstract
The utility model relates to a driving structure of an electric vehicle, comprising a motor supporting frame and a driving motor mounted on the motor supporting frame. The utility model is characterized in that a driving shaft of the driving motor passes through the motor supporting frame to be installed, the driving shaft positioned at the other lateral of the motor support frame is fixedly equipped with a motor gear which is constantly meshed with a big gear which is arranged on a gear outer cover via a shaft bearing, the gear outer cover and the motor support frame are in fix installation, the central position of the big gear is equipped with a flywheel which shares the same shaft with the big gear, and a one-way sliding connection manner of a ratchet wheel and a ratchet crawl is employed between the flywheel and the big gear. The driving structure of the electric vehicle can be conveniently installed on an existing ordinary bicycle without power, simultaneously, because a motor driving shaft and bicycle wheel shafts are independently arranged and are connected by a ratchet wheel device, the sliding without power is not obstructed without influencing the driving function of the motor, and the resistance force is extremely small when the bicycle moves forward by pedaling.
Description
Technical field
The utility model relates to a kind of battery-driven car drive configuration, in particular for the drive configuration of Electrical Bicycle.
Background technology
The drive configuration of existing Electrical Bicycle all is that drive motor is directly installed on the wheel shaft of drive wheel, just the output shaft of drive motor and the wheel shaft of bicycle are united two into one, the advantage of this structure is to have omitted the intermediate transfer structure, and the drive efficiency of motor is higher.But also exist not enough simultaneously: 1, complex structure, need do big change to the integral structure of bicycle, poor with the commonality of unpowered attachments of a bicycle.2, when the storage battery power shortage, when needing foot-operated advancing, because the wheel shaft of bicycle---just the output shaft of drive motor---will drive rotor simultaneously and rotate together, advance resistance is bigger.
Summary of the invention
The purpose of this utility model provides and a kind ofly can be installed in easily on the unpowered bicycle, the foot-operated little battery-driven car drive configuration of advance resistance.
For achieving the above object, the utility model is by the following technical solutions:
Battery-driven car drive configuration described in the utility model, comprise motor bracing frame and the drive motor that is installed on the motor bracing frame, its characteristics are: the axle drive shaft of drive motor passes the motor bracing frame and installs, be positioned on the axle drive shaft of motor bracing frame opposite side and fixedly mount motor gear, motor gear and big gear wheel constant-mesh, big gear wheel covers outside gear by bearing installation, gear enclosing cover and the fixed installation of motor bracing frame; In the center of big gear wheel the flywheel coaxial with it is installed, adopt between flywheel and the big gear wheel ratchet, ratchet can unidirectional slip connection mode.
This battery-driven car drive configuration can be installed on the existing common unpowered bicycle easily, simultaneously because motor driving shaft is provided with respectively, is connected with escapement with bicycle shaft, on the basis that does not influence the motor-driven function, do not hinder motorless sliding again, resistance is very little in the time of foot-operated advancing.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the running condition figure of a kind of embodiment of the present utility model on the bicycle drive wheel.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, battery-driven car drive configuration described in the utility model comprises motor bracing frame 3 and the drive motor 1 that is installed on the motor bracing frame 3.The axle drive shaft 2 of drive motor 1 passes motor bracing frame 3, and the shell of drive motor 1 and motor bracing frame 3 are fixed together.Be positioned at fixed installation motor gear 5 on the axle drive shaft 2 of motor bracing frame 3 opposite sides, motor gear 5 and big gear wheel 6 constant-meshes, big gear wheel 6 is installed on the gear enclosing cover 4 by bearing 7, gear enclosing cover 4 and 3 fixed installations of motor bracing frame; In the center of big gear wheel 6 flywheel coaxial with it 8 is installed, adopt between flywheel 8 and the big gear wheel 6 ratchet, ratchet can unidirectional slip connection mode.The connection mode of flywheel 8 and big gear wheel 6 is similar to the connection mode between bicycle shaft and the sprocket wheel, that is: make it only to slide to a direction.Certainly, concrete connection mode can also have a variety of, in this not narration one by one.
During use, as shown in Figure 2, motor bracing frame 3 is fixedly mounted on the position of bicycle one side near drive wheel wheel shaft 9, and flywheel 8 is fixedly connected on the outside of the axle skin 10 of bicycle.In the time of drive motor 1 work, drive big gear wheels 6 rotations by axle drive shaft 2, owing to have ratchet, ratchet to be connected between big gear wheel 6 and the flywheel 8, big gear wheel 6 drive flywheels 8 rotate synchronously at this moment, flywheel 8 drives wheel revolutions by the axle skin 10 of bicycle again, advances thereby drive bicycle.When drive motor 1 was not worked, in the time of bicycle coasting or foot-operated advancing, flywheel 8 broke away from big gear wheel 6 and freely rotates, and the resistance that advances greatly reduces.
Claims (1)
1. battery-driven car drive configuration, comprise motor bracing frame (3) and be installed in drive motor (1) on the motor bracing frame (3), it is characterized in that: the axle drive shaft (2) of drive motor (1) passes motor bracing frame (3) and installs, the axle drive shaft (2) that is positioned at motor bracing frame (3) opposite side is gone up fixed installation motor gear (5), motor gear (5) and big gear wheel (6) constant-mesh, on gear enclosing cover (4), gear enclosing cover (4) fixedly mounts with motor bracing frame (3) big gear wheel (6) by bearing installation; In the center of big gear wheel (6) flywheel coaxial with it (8) is installed, adopt between flywheel (8) and the big gear wheel (6) ratchet, ratchet can unidirectional slip connection mode.
