Abstract
The utility model relates to a gearbox four-wheel driving differential mechanism which comprsies a casing of the differential mechanism, wherein a left half axle hole and a right half axle hole are formed in the casing of the differential mechanism, the differential mechanism is in transmission connection with the gearbox, a left half axle and a right half axle respectively penetrating through the left and the right half axle holes are in transmission connection with a transmission mechanism in the casing of the differential mechanism, the extension part is arranged at the outer end of the right half axle hole, the inner diameter of the extension part is larger than that of the right half axle hole, and an internal spline in transmission connection with a transfer case is arraned inside the extension part. After power is transmitted to the differential mechanism by the gearbox, one part of motive power is transmitted to the front wheels,while the other part of motive power is tramnittted to the rear wheels through the transfer case, so that a four-wheel driving function is achieved. The gearbox four-wheel drive differential mechanism has the advantages of stablility in motive power transmission, good maneuverability, strong adhesive force, simple structure and practicality.
Description
Technical field
The utility model relates to a kind of diff, specifically, relates to a kind of change speed gear box 4 wheel driven diff, belongs to field of mechanical technique.
Background technology
Diff is the important component part of automobile dynamic system, the bevel gear of diff by two wounded in the battle keys couples together the transmission shaft of left and right sides two-wheeled, as shown in Figure 1, diff comprises differential casing 1, differential casing 1 is provided with left half axle hole 4 and right axle shaft hole 5, diff and change speed gear box are in transmission connection, the transmission device that left half axle passes in left half axle hole 4 and the differential casing 1 is in transmission connection, the transmission device that right axle shaft passes in right axle shaft hole 5 and the differential casing 1 is in transmission connection, when automobile turning, because vehicle right and left drive wheel stressing conditions changes, feedback is on the semiaxis of the left and right sides, and then the original force balance of destruction planetary wheel, at this moment planetary wheel begins rotation, the turning medial wheel speed is reduced, and turning off-side wheel rotating speed increases, and reaches balance again.
In realizing process of the present invention, the contriver finds to exist at least in the prior art following problem, and diff connects left and right sides two-semiaxle, transmits power to front-wheel, and front-wheel is drive wheel, realizes that two drive function, and road-holding property is poor, and adhesive ability is not enough when turning acceleration.
The utility model content
The technical problems to be solved in the utility model is at above deficiency, a kind of change speed gear box 4 wheel driven diff is provided, overcome poor, the not enough defective of adhesive ability when accelerating of turning of road-holding property in the prior art, after adopting diff of the present utility model, have that 4 wheel driven drives, road-holding property is good, the advantage of strong adhesion.
For solving above technical matters, the utility model is by the following technical solutions: a kind of change speed gear box 4 wheel driven diff, comprise differential casing, differential casing is provided with left half axle hole and right axle shaft hole, diff and change speed gear box are in transmission connection, the transmission device that left and right half runs through respectively in left half axle hole and right axle shaft hole and the differential casing is in transmission connection, it is characterized in that: the outer end in described right axle shaft hole is provided with extension, the internal diameter of extension is provided with female splines greater than the internal diameter in right axle shaft hole in the extension.
A kind of prioritization scheme is connected with part-time case between described female splines and the rear wheel.
After the utility model adopts above technical scheme, compared with prior art, have the following advantages: the mouth of differential casing is provided with extension, be provided with the female splines that is in transmission connection with part-time case in the extension, power is after change speed gear box is passed to diff, and one the tunnel is passed to front-wheel, another road is passed to trailing wheel through part-time case, thereby realize the 4 wheel driven function, the power transmission is stable, and road-holding property is good, strong adhesion and simple in structure, practical.
Below in conjunction with drawings and Examples the utility model is elaborated.
Description of drawings
Accompanying drawing 1 is the structural representation of diff in the prior art;
Accompanying drawing 2 is structural representations of diff among the utility model embodiment;
Among the figure,
The 1-differential casing, 2-extension, 3-female splines, 4-left half axle hole, 5-right axle shaft hole.
The specific embodiment
Embodiment, as shown in Figure 2, a kind of change speed gear box 4 wheel driven diff, comprise differential casing 1, differential casing 1 is provided with left half axle hole 4 and right axle shaft hole 5, diff and change speed gear box are in transmission connection, the transmission device that left half axle passes in left half axle hole 4 and the differential casing 1 is in transmission connection, the transmission device that right axle shaft passes in right axle shaft hole 5 and the differential casing 1 is in transmission connection, the right axle shaft hole 5 of differential casing 1 is provided with extension 2, the internal diameter of extension 2 is provided with the female splines 3 that is in transmission connection with part-time case greater than the internal diameter in right axle shaft hole 5 in the extension 2, part-time case and trailing wheel are in transmission connection.
Power is after change speed gear box is passed to diff, and one the tunnel is passed to front-wheel through left and right sides semiaxis, and another road is passed to trailing wheel through part-time case, thereby realizes the 4 wheel driven function, and the power transmission is stable, and road-holding property is good, strong adhesion and simple in structure, practical.
The above is giving an example of the utility model preferred forms, and the part of wherein not addressing in detail is those of ordinary skills' common practise.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation that carries out based on technology enlightenment of the present utility model is also within protection domain of the present utility model.
