based on the working principle of hydraulic overturning system with unlocking soft shaft in heavy-duty truck cab, the technical problems of using unlocking soft shaft to unlock hydraulic overturning mechanism are pointed out,
and the solution of using self-unlocking hydraulic overturning mechanism in truck cab is proposed. An automatic unlocking of the unlocking cylinder is designed,
and the key points of the design of the self-unlocking cylinder are analyzed and the design structure is given.
The experimental results show that the self-unlocking overturning mechanism designed is easy to operate and not prone to failure.
