Larger inlet pressure: 16MPa
Greater back pressure: 2.1MPa
Higher working oil temperature: 80
Power steering torque: 1.75.0Nm
Greater manpower steering torque: 136Nm
Open core unresponsive steering system
The system has the following characteristics and requirements:
The middle position of the steering gear is in an open state (open core), that is, when the steering gear is not working, the hydraulic oil passes through the steering gear and directly returns to the oil tank.
Simple steering system, more widely used
The system should use a fixed pump for oil supply
Advantages of steering gear:
1. The steering system is simple and low in cost;
2. The steering load does not directly act on the steering wheel, and the operation is comfortable;
3. The steering torque is low, and the steering wheel can be continuously turned freely;
4. There are many product specifiions and a wide range of apprenticeships, ranging from 80-1250mlr, which can meet various needs;
5. Valve blocks with different functions and pressure levels can be connected according to the needs of the system;
6. In addition to the above advantages, the BZZ5 load-sensing full hydraulic steering gear also has the following characteristics:
·Regardless of the load pressure and the speed of the steering wheel, the corresponding flow can be alloed according to the demand of the steering oil circuit to ensure reliable, sensitive and light steering.
·The flow rate output by the oil pump, in addition to the required flow rate for the steering system, can be used by the auxiliary oil circuit to eliminate the power loss caused by excessive oil supply in the steering oil circuit and improve the system efficiency.
The BZZ series steering gear has the characteristics of large steering thrust and low operating torque. It is suitable for hydraulic steering of low-speed heavy vehicles such as construction machinery, forklifts, large and medium horsepower tractors, combine harvesters and other hydraulic steering and hydraulic navigation operations of ships
