Why has the company introduced a hydraulic rear-drive steering axle suitable for four-wheel drive based on mature hydraulic bridge technology?

2021/04/13

Based on mature hydraulic bridge technology, the company has launched a hydraulic rear-drive steering axle suitable for four-wheel drive. The product uses a radial plunger motor to directly drive the tires without an intermediate transmission system. With the help of mature and reliable hydraulic components, the drive is more reliable. The wheelbase can be customized according to user requirements, using double-acting steering cylinders. With the hydraulic bridge, it can provide stronger driving ability, adapt to the complex road surface of farmland, and provide a more reliable guarantee for the whole vehicle to travel.
