In order to obtain a more mature hydraulic four-wheel drive solution, the company newly developed a hydraulic four-wheel drive rear drive steering axle. The bridge adopts imported radial plunger motor with low speed and high torque, no need to use deceleration device. The bridge is used in conjunction with the front hydraulic drive front axle to achieve hydraulic four-wheel drive, and the driving force is increased by more than 30% compared with hydraulic two-wheel drive. The loading test proves that the product has a reasonable solution, strong carrying capacity, and high reliability, making it an ideal four-wheel drive solution for harvesting machinery.
| Average input power | 10KW | Features |
| Speed ratio | 1 | 1. Provide customers with the optimal matching scheme of transmission, hydraulic pressure and power of the whole machine to optimize the performance of the whole machine chassis; 2. The whole machine has compact structure, high reliability and low failure rate. 3. All castings are made of nodular graphite casting materials;. 4. The wheel motor and solenoid valve are all imported from Poclain, which is safe and reliable. 5. Bearings and oil seals all adopt internationally renowned brands. 6. According to customer needs, the displacement of the wheel motor can be adjusted appropriately. 7. According to the needs of customers, match the two-gear box, which can realize the functions of two-wheel drive, four-wheel drive and anti-slip. |
