Example Embodiment

[0026] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0027] The invention is mainly used for vehicles with a rhombus-like chassis, and its four wheels are arranged in a rhombus with one front and one rear and two in the middle. Such as figure 1 As shown, a four-wheel drive system for a diamond-like off-road vehicle of the present invention includes a gearbox 28 connected to an engine, a transfer case 4, a differential between front and rear axles 16, and a differential between the bottom axle and wheels. 20. The output shaft 1 of the gearbox 28 is connected to the input end of the transfer case 4 via the constant velocity universal joint 3, and the power is transmitted to the transfer case 4 from this, and the transfer case 4 plays a role in the power distribution between the shafts and the difference between the shafts. Speed ​​function. The output end of the transfer case 4 has two o...

Abstract

The invention discloses a four-wheel drive system for a rhombus cross-country truck, which comprises a gearbox connected with an engine, a transfer case, a differential mechanism between a front and a rear shafts as well as a differential mechanism between middle shaft wheels; wherein, an output shaft of the gearbox is connected with an input terminal of the transfer case; one line of the output terminal of the transfer case is connected with the differential mechanism between the middle shaft wheels by the front output shaft of the gearbox; the differential mechanism between the middle shaft wheels is connected with a left and a right middle wheels by a middle wheel transmission mechanism; the other line of the output terminal of the transfer case is connected with the differential mechanism between the front and the rear shafts by the rear output shaft of the transfer case; the differential mechanism between the front and the rear shafts is connected with the front and rear wheels by a front and a rear wheel transmission mechanisms. The four-wheel drive system for the rhombus cross-country truck has the advantages of simple and compact structure, low cost, good cross-country drive capacity and wide scope of application.

Description

technical field [0001] The invention mainly relates to the design field of automobile drive systems, in particular to a four-wheel drive system for diamond-like off-road vehicles. Background technique [0002] At present, traditional automobiles have two axles, three axles or even more axles, and a pair of wheels are installed symmetrically on each axle left and right. For ordinary road vehicles, two-wheel drive is mostly used, while for the design of off-road vehicles, heavy-duty vehicles or some special vehicles, four-wheel or more than four-wheel drive is generally used. In order to improve the steering performance of the car, there is a new type of diamond-like vehicle in the prior art. Its four wheels are arranged in a diamond shape, one at the front and the rear, and two in the middle. And turning flexibility has certain advantages. However, the transmission system of the existing diamond-shaped vehicle still adopts the two-wheel drive mode of the front engine and th...
