Description

Technical Field

[0001] This utility model relates to the field of steering drive axle technology for both water and dry land use, and in particular to a steering drive axle for both water and dry land use. Background Technology

[0002] Modern vehicles generally have only one steering knuckle arm. In left-hand drive vehicles, the steering gear is on the left side, and the steering knuckle arm is on the left steering knuckle of the steering axle; in right-hand drive vehicles, the steering gear is on the right side, and the steering knuckle arm is on the right steering knuckle of the steering axle. When the vehicle turns, the steering angles of the left and right wheels are different, so the steering force is also different. When turning inwards, the inner steering knuckle has a larger steering angle, a larger steering gear travel, and a smaller steering force; when turning outwards, the inner steering knuckle has a smaller steering angle, a smaller steering gear travel, and a larger steering force. The steering force differs between inward and outward turns, with outward turns requiring more effort.

[0003] The double steering knuckle arm steering drive axle, disclosed in CN103625550A, includes a drive axle body and a steering knuckle arm, as well as an additional steering knuckle arm. The steering knuckle arm and the additional steering knuckle arm are respectively located on the left and right wheel edges of the drive axle body. The steering knuckle arm and the additional steering knuckle arm are connected to a steering system, which simultaneously applies equal forces to both. The steering system is a hydraulic system, including a steering gear and a power steering cylinder system. The steering gear acts on the steering knuckle arm, and the power steering cylinder system acts on the additional steering knuckle arm. The forces acting on the steering knuckle arm and the additional steering knuckle arm belong to the same circuit. For left-hand drive vehicles, the steering knuckle arm is located on the left side of the drive axle body, and the additional steering knuckle arm is on the right side; the opposite is true for right-hand drive vehicles. This invention's steering drive axle has steering knuckle arms on both the left and right wheel edges, providing greater and more balanced steering force for left and right turns through the control of the steering system.

[0004] However, the above technical solution cannot achieve dual-use in water and dry land, which is not conducive to the stable use of the equipment, so it needs to be improved. Utility Model Content
