II. eccentric shaft eccentric shaft vibration generators, machine vibration is generated by vibration motor drives eccentric shaft high speed rotation. One end of the eccentric shaft and the vibration motor connected, change the Rotary to can change the amplitude of the vibration motor.
III. amplitude modulation device amplitude modulation device mounted on the eccentric shaft, set role of amplitude. Location of the device by changing the amplitude modulation and amplitude modulation block, achieve the purpose of adjusting the amplitude. Amplitude modulation device is a sealed cylindrical welded structures.
IV. damping blocks in order to mitigate the effects of vibration on the frame, the vibration between wheel and front frame with rubber vibration blocks.
V. vibration-wheel-drive motor and reducer vibration-wheel-drive motor, reducer and stand together in front on the frame, gear box output connection on the clubs Board, powered by the motor output shaft to the gear, and then to the plum blossom, plum blossom again to vibrating wheel, driving vibration wheel rotation.
VI. vibration support both ends of the eccentric shaft, walking through the vibration of the bearing on the bearing in the housing, vibration motors by supporting components supported on the right bearing seat. Vibration bearing Sweden SKF bearing or Germany FAG bearing. Walking support assemblies for maintenance-free structure.
The seventh section Steering system
Steering system steering with articulated steering, mainly from the steering gear pump, hydraulic steering gear, two steering cylinders, pressure tubing and other components. Hydraulic steering system installed on the rear frame, through the Steering cylinder telescopic control of vehicle steering.
The eight section Braking system
Braking system in order to ensure the safety of roller working and traveling, YZ18C braking systems equipped with braking, parking brake and emergency brake three.
I. driving brake brake with hydraulic brake. Hydraulic brake controlled by moving the joystick to achieve. Joystick control of control valves back into position, motor driven pump supplying driving traffic to zero, the rollers stop.
II. parking brake and emergency brake when the roller is traveling or working, rear axle and front drive reducer valve control normally closed on multiple pieces of brake is on, without braking effect. When the roller is stopped, several pieces of brake friction locking through a spring force, in a State of braking. Emergency braking is mainly hydraulic servo brake, supported by a mechanical brake. After the emergency brake buttons is pressed, driving pumps swashplate immediately return to zero and hydraulic brake; Meanwhile, gearbox and rear axle brakes also promptly produce precursor braking effect.
Note: in State of emergency shall not be used for emergency braking, especially in the fast-running state.
The nine section Frame
Center of the frame after the frame including the former frame, articulated frame in three parts. Connecting them into a hinged support the upper structure of the machine as a whole.
I. in front of the frame by the scraper before box after box before the Assembly, Board, boards, two side panels and other components. Its main functions are supporting vibrating wheel assembly. For the first frame structure of a typical boxes, combination of high strength steel plate, with sufficient strength and rigidity to resist strong impact force and torque of roller working. Scraper to scrape adhesion under the soil on the drum. Scraper front-end and vibrating wheel clearance of cylindrical surface can be adjusted.
II. after frame after frame fuel tank, protection against roll frame, hydraulic tanks, hydraulic tank supports, panels, frames and other components. Its main function is to support the engine and the cab, fixed rear axle. After the frame of the structure of a rectangular box, front and Center articulated frame in vertical shaft and attached to the front plate, followed by the Assembly of the fuel tank, the middle is grooved steel frame. In order to ensure strength, weak parts of strengthening ribs to strengthen, and trough steel plate with seal sealed into a box girder structure. Rear axle at the bottom plate with bolts and rear axle Assembly of rigid connection. To reduce the effects of vibration, between the engine and rear frame with elastic damping blocks, and you can easily adjust the engine to a horizontal position.
