Four-wheel drive system for rhombus cross-country vehicle

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...

AI Technical Summary

Problems solved by technology

However, the transmission system of the existing diamond-shaped vehicle still adopts the two-wheel drive mode of the front engine and the rear drive of the traditional four-wheel vehicle, which is only suitable for urban road driving, and its passability on non-road ground is limited, thereby greatly limiting It limits its scope of application and is not conducive to its promotion

In order to solve the off-road passability problem of the vehicle, the front, middle and rear wheels must have the driving ability at the same time. Due to the limitation of the wheel arrangement, the traditional four-wheel drive system of the traditional four-wheel vehicle is not applicable
