In order to meet the needs of my country's auto industry to improve product quality and reduce production costs, our company has developed a suspended hydraulic turning system and a suspended hydraulic turning system according to the requirements of major OEMs according to the special working conditions of different models. Adopt advanced technology to design and manufacture, the product structure is reasonable, the operation is light and sensitive, the work is safe, and the failure rate is low. After years of development, it has been widely used in major heavy truck OEMs in China.
The cab hydraulic turning system is installed on the car in order to facilitate the assembly of parts and reduce the work intensity of the truck driver, and to easily lift the car cab when there is a fault. This product greatly solves the many inconveniences brought to you by the flipping structure of the traditional cab.
The cab tilting system includes an oil pump that generates hydraulic power, a retractable hydraulic cylinder that tilts the cab up and down, and a locking mechanism that secures the cab.
Some advantages of the cab hydraulic tilt system:
1. Compared with the traditional cab flip structure, the work intensity of the driver is reduced.
2. It is convenient and fast, which improves the work efficiency and saves the time for the driver to turn over the cab.
3. It is suitable for repairing when the car breaks down while driving in a remote city and there is no one around to help.
The suspension double-acting oil cylinder adds a lever hinge mechanism on the basis of the ordinary oil cylinder. The vibration generated during the driving process and the vibration generated by the engine start will act on the lever, and the lever will move around the cylinder block without causing the piston and guide sleeve seals. of wear. At the same time, a set of ratchet locking mechanism is added to the oil cylinder itself, which solves the hidden safety hazards caused by the sliding and leakage of the oil cylinder during the lifting process. The oil cylinder of this structure can also reduce the working pressure of the system.
The suspension type double-acting oil cylinder adds an expanded pipe section on the basis of the ordinary double-acting oil cylinder, and adopts the differential principle to complete the overturning motion of the cab. The piston moves up and down in the suspension section inside the cylinder, but it will cause the wear of the guide sleeve seal.
Precautions for the use and maintenance of the cab hydraulic turning system:
Warning The cab hydraulic turning system is an important part of the whole vehicle. If the user finds a fault in use, he should go to the designated location of the company for maintenance; the company will not be responsible for the quality accident caused by the user's self-disassembly, repair and improper use .
● At any time, the maximum working oil pressure of the system shall not exceed 40MPa.
● The hydraulic turning system needs to replace the hydraulic oil regularly every year. The deterioration of the hydraulic oil will lead to the premature damage of the entire turning system.
● Once abnormal phenomena such as non-pumping oil, half stroke, high pressure, etc. occur, it is necessary to analyze which part of the hydraulic turning system the problem lies in, and solve it.
● Always check the hydraulic tilting system carefully. Damaged or defective parts should be replaced in time.
● The hydraulic turning system components cannot be welded in any way.
● It should be ensured that the components of the hydraulic turning system are not bumped during use.
● Check once a month whether the oil volume of the hydraulic system is reduced, whether the oil is deteriorated, and whether there are too many impurities. If any bad condition is found, it should be replaced in time. When adding hydraulic oil, the new hydraulic oil must be the same as the original hydraulic oil in the system. mixed oil. It is strongly recommended that this hydraulic system use YH-10 aviation hydraulic oil, which has good low temperature resistance and can ensure that it will not freeze at -30 °C.
● The hydraulic components of the cab hydraulic turning system are connected by high-pressure hoses. When assembling the high-pressure hoses, the tightening torque of the ferrule nuts must be greater than 25N.m
● The wrong installation of the high-pressure hose will cause the cab to turn in the opposite direction to the direction indicated by the operation sign, and the cab cannot be lowered after being lifted. Before installing the high-pressure hose, be sure to refer to the signs to determine the direction of the oil pump and the oil inlet and outlet of the oil cylinder ( The oil pump and oil cylinder rising port have been painted with white logo).
