steering system
The steering system consists of steering wheel, steering shaft, steering gear, steering oil pump and steering
bridge. Steering shaft through the universal joint connected to the steering gear and the connecting shaft
through the universal joint connected with the steering wheel, steering column can be tilted to the
appropriate location, steering axle in the tail at the back of the chassis frame, left and right sides
respectively have a steering knuckle, driven by steering cylinder piston rod through the connecting rod
steering knuckle steering, the steering wheel deflection, implementation
.
5.1 steering axle
The steering bridge is a box-shaped cross-sectional welding structure, which is composed of
steering bridge body, steering cylinder, connecting rod, steering knuckle and steering wheel and
other parts. The steering trapezoid adopts a crank slider mechanism, which is driven by the
piston rod of the oil cylinder through the connecting rod to turn the steering knuckle, so that the
steering wheel is offset, so as to achieve steering. To bridge the pin before and after the fixed
plate by damping pad bolted to the frame on the tail at the back of the shelf, make bridge
physical swing around the pin shaft, steering axle sides of a steering knuckle hub after using two
loaded on the steering shaft taper roller bearing, wheel by fixed onto the wheel rim, bearing
inside containing oil seal, keep the grease in the body cavity wheel and steering knuckle.

6 The braking system
The braking mode of forklift truck consists of two forms: service braking and parking braking.
Service braking refers to the braking method used by forklift truck in the process of operation, using
foot brake braking.When the brake pump to the main brake shoe and auxiliary brake shoe with the same
force on the brake drum, until the upper end of the auxiliary brake shoe and the fixed pin against
the brake shoe, the brake shoe to move in the direction of the drum rotation. Against the fixed pin,
