Abstract

The utility model relates to a synchronous or differential mechanism for the single wheel and the double wheel driven by double motor through chainwheels. The utility model is composed of drive motors, wheels, big gears which are engaged with the gears of the shaft ends of the motors, chainwheels which are used to match with the big gears, wheel shafts which is used to assemble the chainwheels, shaft sleeves which are matched with the wheel shafts, etc. The chainwheels are used to solve the problem of poor simultaneous and differential performances of the drive wheels of the double motor. The utility model can replace the expensive electronic differential mechanism to be applied to the lightweight vehicle. The utility model has the advantages of simple structure, convenient manufacture, low cost, and wide application.

Description

Utilize sprocket wheel to realize the synchronous and differential gear of the single, double wheel of Dual-motors Driving
The utility model belongs to a kind of synchronous and differential gear of drive wheels.
The disc type motor special that existing battery-driven car is used, restriction because of constructional feature (no iron core), maximum power has only 200W, when being applied to (motor bike etc.) than high-power driving, under power must use two motors could satisfy the requirement of its rideability (speed, climbing, startup) simultaneously.And two motor-driven biggest obstacles of this application are exactly to be difficult to solve synchronously and the needs of differential.If then cost an arm and a leg with electronics synchronization discrepancy speed device, can't be applied to commodity, make the buyer be difficult to bear its price level.
The purpose of this utility model is the defective at above-mentioned prior art, design-calculated is a kind of to replace existing expensive E-Diff, and can be applied to the wheel driver of the synchronous and differential that utilizes the single, double wheel of sprocket wheel realization Dual-motors Driving of the light-duty vehicle.
The method that the utility model is finished is: the gear on the rack-mounted drive motor axle, be installed in big gear wheel engagement in the gear case and the sprocket wheel adapted, sprocket wheel is installed on the center shaft of wheel, the center shaft of wheel and the wheel axle sleeve adapted, brake facing and the wheel hub adapted that are installed in the wheel hub.During work, utilize the sprocket wheel that is installed on the axletree just changeing driving, the principle that counter-rotating is free to slide.When two motors simultaneously during drive wheels (single, double wheel all can), any platform motor speed height no matter, another all can arbitrarily surmount slip than Low speed electric motor institute wheel driven (two-wheel), thus it is synchronous to reach two drive wheels.Make to surmount to slide by sprocket wheel at Dual-motors Driving single-wheel (coaxial) Shi Yineng and catch up with higher speed motor-driven speed and reach synchronous than the axle head of slow speed motor.Work as Ackermann steer angle, surmount before outboard wheels (two-wheel) can be arbitrary to and realize the differential needs.When arbitrary motor in two motors do not worked, another motor still can the driven wheel, and is not killed parking.
Advantage of the present utility model: simple in structure, making, easy for installation; Use the synchronous and differential problem of wheel that chain sprocket structure can solve Dual-motors Driving, and performance is very reliable, cost of product is low, uses through being installed in single, double the wheel on the battery-operated motor cycle, and effect is very good; For miniwatt disc type electric machine Dual-motors Driving has been finished the utility goods function, desirable generation expensive E-Diff and be applied to the light-duty vehicle; During the vehicle linear running, two motors drive simultaneously, moment balance, and the efficient height, vehicle operating is steady, if a motor breaks down, drives with unit, still can make driving protect fast smooth running; Overcome the problem that the primary electron diff can not accurately be coordinated when vehicle turns round running; Widely applicable, market outlook are wide.
Accompanying drawing 1 is the structural representation of the utility model Dual-motors Driving dual wheels, and Fig. 2 is the structural representation of Dual-motors Driving single wheel.
Most preferred embodiment of the present utility model is: the axle head of rack-mounted drive motor (6) stretches in the gear case (5), gear of motor shaft end (4) and interior big gear wheel (9) engagement of gear case, big gear wheel and the installing and locating sprocket wheel (3) on axletree (10) is equipped with adapted, axletree and axle sleeve (8) adapted that is installed in the wheel hub (7) are installed in wheel (1) middle part with the wheel hub of brake facing (2) adapted.

Claims (1)

  1. A kind of synchronous and differential gear that utilizes sprocket wheel to realize the single, double wheel of Dual-motors Driving, comprise wheel, drive motor, brake facing, the shaft end gear (4) and big gear wheel (9) engagement that is installed in the gear case (5) that it is characterized in that rack-mounted drive motor (6), be equipped with sprocket wheel (3) installing and locating of adapted on axletree (10) with big gear wheel, axletree and axle sleeve (8) adapted that is installed in the wheel hub (7) are installed in wheel (1) middle part with the wheel hub of brake facing (2) adapted.
