Abstract
The invention discloses a heavy truck duplex driving axle capable of achieving double speeds. The driving axle is composed of a middle axle assembly and a rear axle assembly, and is characterized in that a power transmission system of the middle axle assembly is composed of an input flange, an input shaft, an end cover, a box body, a planetary speed reducing device, a spline sleeve, a sliding meshing sleeve, a fixed support, an output shaft, an inter-axle differential assembly of the duplex driving axle, a driving cylindrical gear, a driven cylindrical gear, a driving bevel gear, a driven bevel gear pair, an inter-wheel differential assembly, a half shaft (19), a through shaft, an inter-axle transmission shaft and the rear axle assembly; a control system of the middle axle assembly is composed of a spline sleeve, a sliding meshing sleeve, a fixed support, a shifting fork and a reversing valve assembly. The driving axle has a speed change function, the use range of a truck is wider, andthe driving axle has the advantages of being simple and compact in structure, having few reversing elements, being high in transmission efficiency and the like.
Description
Technical field: [0001] The present invention relates to the technical field of heavy-duty trucks, in particular to a double-connected drive axle for heavy-duty trucks that realizes two speeds; it effectively makes up for the shortcomings of a gearbox with few gears or a small shift range of an automatic gearbox, and makes the double-connected axle With the function of speed change, the drive axle can match more models and the applicable range of vehicles is wider. Background technique: [0002] Heavy-duty truck axles undertake the functions of carrying, traveling, braking, increasing torque, transmitting torque and reasonably distributing it to the left and right wheels. When the car is fully loaded, the axle needs to output a large torque, and the high torque of the axle is generally achieved by the gearbox, but the gears of the gearbox are limited, and increasing the gear means that the structure is more complicated and the cost is higher. High, and it is difficult for t...
