Description
Technical field
The present invention relates to a kind of Electrical Bicycle, be specifically related to a kind of Electrical Bicycle with mid-engine installation.
Background technology
At present, Electrical Bicycle is divided into mainly by type of drive that front wheel hub drives, rear-wheel hub drives and mid-engine installation drives three kinds.The front wheel hub type of drive only accounts for very small scale owing to there is the problem of road-holding property wretched insufficiency when riding.And the rear-wheel hub type of drive is because the rear-wheel hub motor has occupied back shaft position, therefore can not back axle mounting internal speed changer or outside change-speed box, the adaptive capacity of different road conditions depends on tractive performance---torque, the rotary speed property of motor fully, low-speed big facing the wind or climbing waits its sexuality to be very limited, can't expand.Mid-motor drive mode since its installation site at the middle part of battery-driven car, compact conformation is reasonable, with car---robot system center of gravity line position is close good stability; Because motor is directly carrying not, its tractive performance is more powerful; Thereby changed the weight that wheel hub in the present wheel hub drive configuration should be born car body and bicyclist, needed the most unfavorable processing condition of transmission of drive force square again; Because trailing wheel is identical with the ordinary bicycle structure, the maintenance trailing wheel is also convenient.In the being seen in the market mid-engine installation, motor and pedal are exported by two axles, and complex structure, engine installation take up room greatly, and what adopt on gear transmission is that complicated multi-stage gear transmission causes fault frequent, inconvenient maintenance.
In addition; the comparatively general type of drive of existing Electrical Bicycle is chain gear; promptly comprise with engine installation bonded assembly big chain plate, with little chain drum of adhesion wheel axle bonded assembly and chain; chain is easy to come off from chain drum; easy handle is made dirty when hanging again, exposes greasy dirt on the chain clothes of also usually can making dirty.The transmission device that adopts the shaft drive mode is also arranged at present, and its power conducting piece is a rigid shaft, and a sets of transmission mechanism only is applicable to a vehicle, if be used for other a car then need redesign the length of rigid shaft, causes a large amount of wastes of productive costs.
Summary of the invention
The present invention is directed to complex structure, the many defectives in trouble point that existing Electrical Bicycle with mid-engine installation exists, a kind of compact conformation, in light weight, Electrical Bicycle that cost is low are provided, its type of drive adopts the flexible axle transmission, and fault rate is low, and comformability is good.
The technical solution used in the present invention is:
A kind of Electrical Bicycle with mid-engine installation, comprise vehicle frame, motor, axis, housing and transmission device, engine installation drives the adhesion wheel axle by transmission device, motor output shaft is provided with driving gear, be arranged with driven gear on the axis, driving gear and driven gear are by the carrier gear engaged transmission; Described transmission device comprises and driven gear bonded assembly first finishing bevel gear cuter and the first finishing bevel gear cuter ingear middle tap gear, with the 4th finishing bevel gear cuter of adhesion wheel axle bonded assembly third hand tap gear and third hand tap gear mesh, pass through the flexible axle transmission between middle tap gear and the 4th finishing bevel gear cuter.
Be arranged with free-wheel clutch on the described axis, the axis two ends are connected with the pedal crank throw, and free-wheel clutch comprises inner ring and outer ring, and inner ring is captiveed joint with axis, and the outer ring is described driven gear.
Described housing has the opening that the power supply machine output shaft stretches into, motor housing and housing are fitted and are installed, and are provided with two bearings in the housing, are equipped with the carrier gear installation shaft in the bearing, carrier gear is located on the installation shaft, and driving gear, carrier gear and driven gear all place in the housing.
Described motor output shaft and driving gear are one-body molded.
Described first finishing bevel gear cuter and the sealing of middle tap gear are arranged in the engine installation housing; Described adhesion wheel shaft end is provided with case, and described third hand tap gear and the sealing of the 4th finishing bevel gear cuter are arranged in the adhesion wheel axle case.
Described flexible axle is a steel rope, is arranged with flexible sleeve on the flexible axle.
The invention has the beneficial effects as follows: mid-engine installation is by gear cluster direct drive transmission device, it is little to take up room, in light weight, by two pairs of bevel gear driving Electrical Bicycle driving wheels, no metal bump and grating in the transmission process, and effectively avoid the chain fault; Free-wheel clutch be arranged so that when electric operation and manpower were ridden, pedal crank throw and carrier gear did not disturb mutually; Transmission device is hidden, and no exposure portion effectively prevents to pile up dust; Motor output shaft and driving gear are one-body molded, reduce the fault point and motor operation more stable; Flexible axle can extend and shorten, and is not subjected to the restriction of the specific vehicle of certain money, goes for a series of Electrical Bicycle, is arranged with flexible sleeve on the flexible axle, and the protection flexible axle is to avoid stained.
