(2) Hydraulic travel drive system
The closed hydraulic drive system composed of variable variable pump and double variable motor realizes the full drive of the front and rear wheels, ensuring that the road roller has good driving performance and climbing ability. The four-speed continuously variable transmission ensures that the operation can be carried out at the most suitable speed under different working conditions. Gear is used for compaction operations, at which time the climbing ability is the highest. Gears and are used respectively under the conditions of front and rear wheels slipping to avoid machine skidding to a certain extent. field velocity.
(3) Transmission system
The domestic heavy-duty drive axle is adopted.
(4) Hydraulic vibration system
The closed hydraulic system is composed of variable variable pump and quantitative motor, double frequency, double amplitude, scientific and reasonable static line load and exciting force configuration, to ensure effective compaction of different types of materials and layers of different thicknesses.
The hydraulic vibration system adopts damping control anti-hydraulic shock technology, which not only reduces the hydraulic shock of the vibration system, improves the reliability of the system, but also makes the vibration start and stop stable, avoids the impact on the compacted material, and improves the compaction. uniformity.
(5) Vibration wheel
The vibrating wheel is the core component of the vibratory roller. The XCMG vibrating wheel adopts the structure of the inner cylinder vibration chamber, and applies the long-life vibrating wheel design technology and the ultimate pressure equalization technology. It has simple structure, high strength, good rigidity, dual-frequency and double-amplitude functions, large static line pressure and exciting force, high operating efficiency, long service life of vibration bearings, and high reliability.
XCMG’s long-life vibrating wheel has achieved breakthroughs in the following aspects:
* Vibration bearing life
The vibration bearing is a key component to support vibration, and improving the life of the vibration bearing is of great significance for improving the life of the vibration wheel. XCMG studied the lubrication of vibration bearings under different conditions through repeated tests on the self-made vibration wheel test bench, and jointly developed a specially designed reinforced XCMG special vibration bearing with a theoretical life of more than 10,000 hours.
* The service life of transmission parts
The exciter and spline sleeve are the key components in the vibrating wheel. XCMG XS263 redesigned the exciter to reduce the impact on the spline pair during vibration start and ensure the reliability of the transmission system while ensuring the vibration parameters. , thereby improving the life of the vibrating wheel.
* Vibration wheel sealing technology
The vibrating wheel adopts a double-skeleton oil seal structure, and double channels prevent oil leakage, which greatly reduces the leakage of lubricating oil in the vibrating chamber and improves the reliability of the vibrating wheel.
* Super conversion design
It realizes the fast conversion of the cam wheel and the smooth wheel, and improves the adaptability of the whole machine to working conditions.
(6) Control system
According to the principle of ergonomics, the instrument box integrates the steering wheel, various instruments, key start switch and other components, which is beautiful and practical, and improves the operating comfort. The control box is located on the right side of the seat, which is convenient and labor-saving to operate. Suspended seat with safety belt, safe and comfortable.
(7) Electrical system
The electrical system includes starting circuit, power circuit, parking circuit and fault alarm system, etc.; equipped with a large-screen combination instrument, the parameters of the whole machine are displayed in real time, and maintenance and repair information as well as the working status of the engine can be provided at any time to avoid “sick” operation of the equipment. Control buttons and switches are accurate, sensitive and reliable.
The system is in the form of integrated control, which integrates the scattered assembled relays and fuses in the instrument box to reduce the number of wires, and the lines are scientifically coded and designed to realize centralized fault detection.
(8) Brake system
The brake system is composed of drive axle, multi-plate brake on the vibrating wheel reducer and the hydrostatic brake of the closed hydraulic system. It has three functions of driving, parking and emergency to ensure safe and reliable driving.
(9) Cab
Good sealing performance, equipped with air conditioner, retractable machine, suspension seat, large internal space and equipped with large area of ??glass, wide field of vision, providing a safe and comfortable operating environment for the driver. Optional anti-roll cab.
The driver’s vision complies with the relevant provisions of GB/T16937.1 “Earthmoving Machinery Driver’s Vision Guidelines”.
(10) Hood
The engine cover of XCMG road roller adopts advanced metal overall molding manufacturing technology, which replaces the popular glass fiber reinforced plastic molding material in the market. Beautiful and smooth. The engine hood adopts a new electro-hydraulic control method, with a large opening angle, so that the maintenance parts can be seen at a glance. The opening and closing of the engine hood can be controlled on the control box of the cab, which brings great convenience for maintenance.
(11) Heat dissipation and vibration reduction technology
* Guide type air duct heat dissipation technology
The new air duct design allows the engine to take in air from the left, right and top of the hood, and exhaust from the rear of the hood after the engine circulates, reducing eddy currents, improving heat dissipation, and ensuring efficient operation of the power system;
* Flexible close heat dissipation sealing technology
Nylon material brushes are used, assembled on an aluminum metal plate, and tightly attached between the radiator and the frame, effectively sealing and cutting off hot and cold air, improving heat dissipation, and ensuring efficient operation of the power system;
* Three levels of vibration reduction
Including vibrating wheel vibration damping, seat vibration damping, and cab vibration damping. The shock absorber has passed CAE simulation analysis. The cab adopts three-dimensional vibration damping technology, and the vibration wheel damper layout is optimized to ensure excellent vibration damping effect.
