Abstract
The invention provides a four wheel drive mechanism capable of maintaining advantages and overcoming partial disadvantages on the basis of a full-time four wheel drive principle aiming at the advantages and disadvantages of a part-time four-wheel drive vehicle, a full-time four-wheel drive vehicle and a real-time four-wheel drive vehicle. The four wheel drive mechanism can achieve rear wheel drive, full-time four wheel drive and the locking of a center differential through electric and manual gear changing, and has a compact structure and high efficiency.
Description
Technical field: this is a kind of automobile 4 wheel driven mechanism, this 4 wheel driven mechanism is applicable to the four wheel drive of cross-country car, car and SUV car.
Background technology: I am at previous an invention " a kind of automobile 4 wheel driven system of fuel-economizing, application number; 2010101493811 " inner introduced a kind of change-speed box horizontal can forerunner, the mechanism of AWD, the locked 4 wheel driven of diff, now I or according to former without shell differential design principle, designed a kind of change-speed box vertical put can rear-guard, AWD, the locked 4 wheel driven mechanism of diff.Summary of the invention: for the merits and faults of half, full-time, in good time three kinds of 4-wheel driven cars, I taking AWD principle as basic design a kind of 4 wheel driven mechanism that can keep its advantage and can overcome again part shortcoming, the 4 wheel driven that rear-guard, AWD and center differential are locked can be accomplished by electronic and manual engage a gear, compact conformation excellent in efficiency by this 4 wheel driven mechanism.
Brief description of the drawings: Fig. 1 is instruction diagram, and Fig. 2 is the cutaway view of Fig. 1 at A-A place, and Fig. 3 is the explanation to 4 wheel driven gear, and Fig. 4 is the explanation to the locked gear of 4 wheel driven.The mechanism of the locked 4 wheel driven of a kind of rear-guard 4 wheel driven comprises; Transmission output shaft 1, front driving gear 2, spline housing 3, engage a gear cover 4, half front axle gear 5, cross bar 6, check screw 7, pivot pin 8, planetary wheel 9, rear axle side gear 10, adjusts bung flange 11, front ring gear 12.
In the straight-through part-time case of transmission output shaft 1.On transmission output shaft 1, have front driving gear 2, front driving gear 2 is by needle bearing and transmission output shaft 1 floating connection, and there is female splines at its rear portion.Spline housing 3 has interior male splines, the spline joint of its female splines and transmission output shaft 1, and external diameter has two splines, and the centre of two splines is grooves.The effect of spline housing 3 is connected axle 1 exactly with half front axle gear 5, make diff locked.The internal diameter of half front axle gear 5 and transmission output shaft 1 floating connection, external diameter has spline.The internal diameter of engage a gear cover 4 has two splines, and external diameter has the groove of a spline and an engage a gear.The rear portion of transmission output shaft 1 and the internal diameter spline joint of cross bar 6, cross bar 6, check screw 7, pivot pin 8, planetary wheel 9 is combined becomes planetary gear carrier, power is transferred to half front axle gear 5 and rear axle side gear 10 by planetary gear carrier, and by planetary gear carrier differential.Planetary gear carrier and front and back axle side gear composition diff.Adjust the turn of bung flange 11 and can adjust diff gap.Front driving gear 2 and front ring gear 12 can pass to front propeller shaft power.
Can manually also can be electronic to the manipulation of engage a gear cover 4, Fig. 1; Engage a gear cover 4 is in rear positions; Half front axle gear 5 engage a gears cover 4 and spline housing 3 and transmission output shaft 1 spline joints, diff is by locked, and power leads directly to rear propeller shaft, and front driving gear 2 is also in quick condition, front output shaft does not have power.Fig. 2 engage a gear cover 4 is at medium position; Half front axle gear 5 engage a gear cover 4 and front driving gear 2 spline joints, this is AWD.Fig. 3 engage a gear cover 4 is in forward position; Half front axle gear 5 engage a gears overlap 4 front driving gear 2 spline housings 3 and all spline joints of transmission output shaft 1, are at this moment the locked 4 wheel drivens of diff.
Detailed description of the invention: first need a few cover samples of development and design to test, pinpoint the problems and deal with problems, if the fine reliable operation of performance just can be considered batch manufacturing, the market outlook of this mechanism should be fine.But development cost may be very high, so need the support of investment funds, auto maker, auto parts and components manufacturing company, preferably can obtain government and support.
