Description
Technical field
The utility model relates to electric automobiles, is specially a kind of battery-driven car with compound vehicle wheel structure.
Background technology
Now widely used electric bicycle wheel system is flower wheel, driving wheel structure concept, be about to rely on to be transferred to that the wheel of torque movements is called drive wheel on the wheel circumference, relies on the flower wheel of the wheel meaning that wheel center thrust rolls; Drive wheel is also born vehicular load.Classical wheel movement mechanics principle discloses, and in this conventional wheel system architecture, larger its required thrust of flower wheel radius size is less, and less its propulsive effort of drive wheel radius size is larger.People do not respect and take full advantage of these groundworks in the practice, battery-driven car adopts wheel to be equal to the technical schemes full of contradictions such as the function of radius, drive wheel is overlapping always, cause battery-driven car power obviously too high, hard case that operating range is limited brings invisible obstruction to social development.
Summary of the invention
Obviously too high in order to overcome existing battery-driven car power, the deficiency that operating range is limited, the utility model aims to provide a kind of compound vehicle wheel structure electric car, this battery-driven car is according to the wheel movement mechanics principle, by increasing vehicle flower wheel radius size, reducing the target that drive wheel radius size and reasonable disposition power just can be realized automobile energy-saving.
To achieve these goals, the technical scheme that adopts of the utility model is:
A kind of compound vehicle wheel structure electric car, its constructional feature are to comprise being contained in the compound vehicle wheel that is combined by load wheel, drive wheel, wheel hub axle sleeve, fixed hub, power transmission shaft on the vehicle frame trailing wheel position; Described power transmission shaft is contained in the vehicle frame trailing wheel section, and described fixed hub is housed on this power transmission shaft; Drive wheel bracket and wheel hub axle sleeve are housed on the described fixed hub; On the described drive wheel bracket drive wheel is housed; The load wheel is housed on the described wheel hub axle sleeve; Described drive wheel one side is provided with the with it driving head of captive joint, and this driving head and motor power output link; The radius of described drive wheel is less than or equal to half of load wheel radius.
Thus, described fixed hub is connected with the vehicle frame drive wheel bracket, realizes the wheel fixed function; The wheel hub axle sleeve is connected with the load wheel, and the realization load is taken turns independently flower wheel attribute function; Power transmission shaft is connected with transmission of power wheel, trailing wheel sprocket, independently drives function to realize transmission of power and drive wheel.
In the utility model, by bearing fixed hub is housed on the described power transmission shaft, by bearing the wheel hub axle sleeve is housed on this fixed hub, described load wheel is contained on the wheel hub axle sleeve.
As a kind of concrete form of transferring power, transmission of power wheel and the trailing wheel sprocket of captiveing joint with the transmission of power wheel are housed on the described power transmission shaft, described transmission of power wheel links to each other with driving head, and the trailing wheel sprocket links to each other with motor power output.Described trailing wheel sprocket is connected with magneto-electric machine output, makes power transmission shaft obtain thus power, and this power is connected with the driving head of drive wheel through the transmission of power wheel again, with this power driven driving wheel of vehicle.
Further, be meshed transmission gear between described transmission of power wheel and the driving head or pass through the chain sprocket transmission.Certainly, also can pass through belt-driving between described transmission of power wheel and the driving head.
Described drive wheel bracket is connected to the junction of vehicle frame and fixed hub.
As a kind of preferred version, described load wheel both sides are equipped with drive wheel.
Described motor power is output as disc-type permanent magnet motor.
By said structure, the utility model casts off the conventional wheel structuring concept once and for all, the Wheeling System structure of foundation take the load wheel as main body, thus, radius of wheel is large as far as possible in lock torque efficient range inside dimension, less in the hope of the required propelling thrust of vehicle movement, reach vehicle operating labour-saving purpose.
The utility model changes the mode that the conventional wheel radius size is equal to, radius is set separately takes turns the wheel of 1/2 radius size less than load as drive wheel (non-load wheel), this takes turns and does not bear vehicular load, only for vehicle movement provides required propulsive effort, in the hope of obtaining significantly to strengthen the purpose of propulsive effort.
The utility model changes the mode that the conventional drive wheel has load concurrently, drives dual-use function, employing is take the load wheel as main body, by link drive wheel (non-load wheel) is set in its both sides, makes vehicle rear wheel become the structure of large steamboat one, consist of the compound vehicle wheel mode; By selecting suitable compound vehicle wheel width, regulate adhesion of wheels, make compound vehicle wheel not only have independently load function and driving merit, and power is abundant, its trafficability characteristic is not subjected to the restriction of small-wheel-diameter yet.
The utility model adopts the wheel left side that the mode that disc-type permanent magnet motor drives is set.
The such scheme innovative point mainly concentrates on the thorough change of rear wheels of electric vehicle structure:
⑴ vehicle rear wheel adopts the compound vehicle wheel technology, sets up drive wheel as the basis in its both sides take the load wheel, realizes the target of wheel function singleness, hydrodynamics;
⑵ compound vehicle wheel structure is to rely on wheel shaft mode with three-decker, and wheel shaft is comprised of power transmission shaft, fixed hub, wheel hub axle sleeve, and the compound vehicle wheel structural element is provided;
⑶ the drive wheel radius realizes significantly improving the vehicle drive force target less than (or equaling) 1/2nd loads wheel radius in the compound vehicle wheel;
⑷ compound vehicle wheel width can be regulated, and sets suitable vehicle adhesive ability.
Compared with prior art, the beneficial effects of the utility model are: after adopting the combined wheels structure, the utility model vehicle promotes under the condition that does not increase former vehicle power that load wheel is laborsaving, drive wheel is powerful, realized significantly energy-conservation target, started the new situation of automobile energy-saving.
Below in conjunction with drawings and Examples the utility model is further elaborated.
