The invention discloses a large-rotating-angle wet
brake steering axle. The Large-rotating-angle wet
brake steering axle comprises an axle body, steering knuckles, main pins, hubs, wet brakes, a tie rod and a steering oil cylinder. The two ends of the axle body are connected with the hubs and the steering knuckles through the main pins correspondingly. By rotating a
steering wheel, oil is injectedinto the oil cylinder through an oil
pipe connected with the steering oil cylinder, thus, a
piston of the steering oil cylinder is pushed to move in the left-and-right direction, a
piston rod is driven to move, the tie bar is connected with the two steering knuckles, the
piston rod moves to drive the steering knuckles to rotate, thus, the hubs rotate, the hubs are acted through the wet brakes forbraking, guarantees can be achieved in different harsh environments, at the same time, the requirements of the smaller steering structure and the larger
steering angle are met, the wet brakes are used for replacing original drum brakes or clamp brakes, a vehicle has stable and good braking performance in different use environments, the structural
layout is smaller and more compact, and the
performance requirement of the large rotating angle can be met.
