In recent years, the sales volume of heavy trucks has increased rapidly. For heavy trucks with cab weight of more than 500kg, the traditional manual turnover and driving turnover system locked by mechanical torsion bar mechanism can not adapt, but is gradually replaced by hydraulic turnover and locking mechanism.
The hydraulic lifting cylinder is the executive part of the system, and the upper and lower fulcrum are respectively connected with the chassis and cab; The hydraulic lock ensures reliable locking when the cab is in the normal position. The most important index of hydraulic lifting cylinder is self-locking ability (anti crawling ability is required to ensure the reliable support of the cab at any position. This content mainly depends on the performance of all seals of the hydraulic cylinder and the hydraulic control check valve. It is required that the crawling at any position shall not exceed 2mm per hour. The other content is the free falling height and free floating length. The appropriate free falling height can ensure the reliable locking of the hydraulic lock when the cab is lowered, the same as The free floating area is an important guarantee for the comfort of the cab.
