A steering arm assembly includes a steering arm body, a first rotary connecting part and a second rotary connecting part. A first end and a second end of the steering arm body are fixedly connected with a first rocker arm and a second rocker arm, respectively. The first rotary connecting part and the second rotary connecting part are respectively connected with the first end and the second end of the steering arm body, and the steering arm body is configured to rotate relative to the first rotary connecting part and the second rotary connecting part. The steering arm body is able to be detachably located on a mounting bracket through the first rotary connecting part and the second rotary connecting part; and the first rotary connecting part and the second rotary connecting part respectively include a first shaft housing and a second shaft housing, which are engaged with a first mounting plate and a second mounting plate respectively.

Steering arm assembly, steering mechanism and multi-axle steering wheel type heavy duty vehicle

The present invention relates to a steering system and an independent suspension wheel-type heavy vehicle. The steering system comprises a steering mechanism for providing a steering force to wheels and a steering hydraulic assisting system for providing a steering assisting force overcoming a steering resistance moment from the ground to the wheels. According to the invention, by providing the steering mechanism for providing a steering force to wheels and by providing the steering hydraulic assisting system for providing a steering assisting force overcoming a steering resistance moment from the ground to the wheels, the steering resistance moment from the ground can be effectively overcome, and the vehicle is offered the steering capability for various places, as compared with a steering system only depending on the torque output by a steering gear or only depending on the torque output by the steering gear and a steering assisting follower.

Steering system and independent suspension wheel-type heavy vehicle

Disclosed are a follow-up steering control system for a multi-axle automobile crane and the multi-axle automobile crane. In a steering state of the multi-axle automobile crane, an output oil pressure of a first oil pressure output port is greater or less than that of a second oil pressure output port; a piston rod of a left-turning hydraulic cylinder is lengthened and a piston rod of a right-turning hydraulic cylinder is shortened, or the piston rod of the left-turning hydraulic cylinder is shortened and the piston rod of the right-turning hydraulic cylinder is lengthened; and a first knuckle arm and a second knuckle arm are driven to make a rear left steering wheel and a rear right steering wheel turn left or right.
