Problems solved by technology
With the expansion and development of the domestic military vehicle and off-road vehicle market, neither of the above two forms can well meet the requirements of light weight, low fuel consumption and high reliability of military vehicles and off-road vehicles;
[0003] In addition, the ball cage universal joint and double joint universal joint assembly have many parts, complex structure, poor weight reduction index, and increase the cost of manufacturing, assembly and maintenance.
Due to the large axial and radial dimensions of the double-joint universal joint assembly, it is difficult to arrange the expansion and contraction length of the input shaft splines on the wheel side of the independent suspension

The invention relates to a steering drive axle with independent suspension and single cross axle wheel-side transmission, which is characterized in that a main reducer is connected with a flange yoke; the flange yoke is matched with a weld yoke and a spline shaft yoke; an input shaft yoke is fixed on a wheel-side reducer; the wheel-side reducer is connected with a wheel hub; the connection line between an upper fulcrum and a lower fulcrum of an independent suspension arm is the main pin central line; the intersection point of the main pin central line and the axis of a half axle is the centerof a universal joint; the main pin central line and the universal joint center of the wheel-side reducer are superposed with the center of a steering joint when a wheel-side planetary gear train is formed; and the spline shaft yoke and the weld yoke can move axially in a telescopic mode. The wheel-side reducer adopts a single pair of externally-engaged cylindrical gears or a planetary gear reducer; and the wheel-side input shaft is a single cross axle universal joint with a telescopic joint. The steering drive axle with independent suspension and single cross axle wheel-side transmission has higher torque bearing capability and can well meet the requirements of light weight, low oil consumption and high reliability of military vehicles and off-road vehicles.
Description
technical field [0001] The invention relates to a steering drive axle with independent suspension and single cross-axis wheel-side transmission, which belongs to the automobile manufacturing industry and is suitable for various types of commercial vehicles, mainly for military vehicles and off-road vehicles. Background technique [0002] At present, most of the wheel drive steering axle structures of independent suspension commercial vehicles use the main reducer to connect with the wheel reducer through various universal joint wheel input shafts to realize the transmission of torque, and at the same time the wheel input The universal joint on the side of the shaft close to the wheel reducer is also responsible for steering. At present, the most widely used in independent suspension and wheel drive steering axles are ball cage universal joints or double universal joint wheel drive forms. The wheel-side transmission form of the ball cage universal joint has strict lubricatio...
