Abstract

The invention relates to a steering drive axle with two steering knuckle arms. The steering drive axle comprises a vehicle frame, a first steering axle, a second steering axle and a dual power steering device. The first steering axle comprises a first left steering knuckle arm body and a first right steering knuckle arm body, the second steering axle comprises a second left steering knuckle arm body and a second right steering knuckle arm body, both the first left steering knuckle arm body and the first right steering knuckle arm body are connected with the dual power steering device, the dual power steering device comprises a power steering gear and a steering actuation cylinder, the power steering gear is connected with the first left steering knuckle arm body, and the steering actuation cylinder is connected with the first right steering knuckle arm body. An original single-front-axle steering system is adjusted to an existing dual-front-axle steering system, dual power steering is adopted to solve the problems of insufficient dual-front-axle power steering and hard steering, and the dual front axes each comprise one left steering knuckle arm body and one right steering knuckle arm body, provide larger and more balanced steering force when a vehicle turns left or right, are easy to implement, have good technological and economical value and are suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to a steering drive axle of a vehicle, in particular to a double steering knuckle arm double steering drive front axle. Background technique [0002] The steering system of the current vehicle is generally a single front axle steering system, that is, a double-piston double-acting oil cylinder is installed on the front axle I-beam, and the left and right steering knuckle arms are controlled by the oil cylinder to realize steering. During use, the load on the existing single front axle steering system is too great. [0003] The steering system of the front axle generally has only one steering knuckle arm. The steering machine of the left-hand drive vehicle is on the left side, and the steering knuckle arm is on the left steering knuckle of the steering bridge; the steering machine of the right-hand drive vehicle is on the right side, and the steering knuckle arm is on the right on the side steering knuckle. When the vehicle is tu...
