HOWO 6x4 garbage mobile refuse compactor

Feature:

Powertrain system:

Howo rear loader truck equipped with WP10.340 inline 6-cylinder diesel engine, high-pressure common rail fuel injection system, variable-section turbocharging (VGT) and intercooling technology, it achieves a maximum power output of 340HP/1800rpm and a continuous output of 1500N·m peak torque in the range of 900-1400rpm. This power configuration is specially optimized for the frequent start-stop conditions of garbage trucks, and the low-speed and high-torque characteristics significantly improve the starting and acceleration performance.

Chassis transmission system:

——Drive architecture: Adopting 6×4 all-wheel drive layout, the front axle load is 7.5 tons, the rear double drive axle load is 18 tons (13 tons + 5 tons thrust structure), with 8.25R20 all-steel radial tires, the minimum turning radius is ≤10m, taking into account both heavy-load passability and urban lane mobility.

——Speed transmission system: Matched with ZF 16S221 OD overdrive gearbox, 12 forward gears + 2 crawler gears + 1 reverse gear, with direct connection design between power take-off and hydraulic pump, to achieve dual-mode power distribution for driving and operation. PTO output power reaches 180kW, ensuring that the vehicle can still move when the hydraulic system is running at full load.

Tank structure:

The three-dimensional parametrically designed arc tank body is laser welded with Q235B high-strength alloy steel, and the longitudinal reinforcement rib spacing is ≤400mm. It can withstand 0.35MPa working pressure after finite element analysis (FEA). The volume utilization coefficient reaches 0.92, which increases the effective loading capacity by 15% compared with traditional square tanks.

Compactor mechanism:

The two-stage piston compactor system is equipped with a φ180mm×3200mm main cylinder, and the compression plate is made of 16MnCr5 carburized steel with a surface hardness of HRC58-62. Dynamic compression force adjustment (adjustable from 50 to 120 kN) is achieved through a pressure compensation valve, and the unit volume garbage density can reach 800 kg/m³ when the compactor ratio is 1:3.4.

Hydraulic control system:

——Intelligent control unit: The CAN bus architecture integrates the Rexroth A4VG electronically controlled axial piston pump and proportional reversing valve, and is equipped with a Siemens S7-1200 PLC controller to achieve closed-loop control of the dozer motion trajectory (repeat positioning accuracy ±2 mm). 8 preset operating modes can be switched with one button through the 7-inch HMI touch screen.

——Energy efficiency management: The original load-sensitive hydraulic system (LS system) enables the pump flow to be distributed on demand, saving 30% energy compared to traditional quantitative systems. The measured single-cycle (compression + unloading) energy consumption is ≤1.2L diesel, which is 18% lower than similar products.
