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 that a kind of automobile is used 4 wheel driven mechanism, and this 4 wheel driven mechanism is fit to the four wheel drive of cross-country car, car and SUV car.
Background technology: my formerly an invention " a kind of automobile 4 wheel driven system of fuel-economizing, application number; 2010101493811 " lining introduced a kind of change-speed box horizontal can the forerunner, the mechanism of AWD, the locked 4 wheel driven of diff; This moment I still according to former no 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 am with AWD principle a kind of 4 wheel driven mechanism that can keep its advantage and can overcome the part shortcoming again that has been basic design; The 4 wheel driven that rear-guard, AWD and center differential are locked can be accomplished through electronic and manual engage a gear, the compact conformation excellent in efficiency by this 4 wheel driven mechanism.
Description of drawings: Fig. 1 is an instruction diagram, and Fig. 2 is the cutaway view of Fig. 1 at the A-A place, and Fig. 3 is that Fig. 4 is the explanation to the locked retaining of 4 wheel driven to the explanation of 4 wheel driven retaining.The mechanism of the locked 4 wheel driven of a kind of rear-guard 4 wheel driven comprises; Transmission output shaft 1, preceding 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, half-rear axle gear 10, adjustment bung flange 11, preceding ring gear 12.
In the transmission output shaft 1 straight-through part-time case.Preceding driving gear 2 is arranged on the transmission output shaft 1, and preceding driving gear 2 floats with transmission output shaft 1 through needle bearing and is connected, and there is female splines at its rear portion.Spline housing 3 has interior male splines, and its female splines is connected with the spline of 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 exactly to be connected axle 1 with half front axle gear 5, makes diff locked.The internal diameter of half front axle gear 5 floats with transmission output shaft 1 and is connected, and 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 of cross bar 6 are connected; 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 half-rear axle gear 10 through planetary gear carrier, and through the planetary gear carrier differential.Planetary gear carrier and front and back axle side gear are formed diff.The turn of adjustment bung flange 11 can be adjusted the diff gap.Preceding driving gear 2 can pass to front propeller shaft to power with preceding ring gear 12.
Can manually also can be electronic to controlling 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 is connected with transmission output shaft 1 spline with spline housing 3, and diff is by locked, and power leads directly to rear propeller shaft, and preceding driving gear 2 also is in quick condition, and 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 gears cover 4 is connected with preceding driving gear 2 splines, and this is an AWD.Fig. 3 engage a gear cover 4 is the position forwardly; Before the half front axle gear 5 engage a gears cover 4 driving gear 2 spline housings 3 and transmission output shaft 1 all spline be connected, at this moment be the locked 4 wheel driven of diff.
The specific embodiment: at first need a few cover samples of development and design to make an experiment, pinpoint the problems and deal with problems, if the performance function well reliably just can be considered batch manufacturing, the market outlook of this mechanism should be fine.But development cost maybe be very high, so need the support of investment funds, auto maker, auto parts and components manufacturing company, preferably can obtain government and support.
