The invention provides a suspension structure of a cab, and relates to the field of cab overturning. The suspension structure of the cab comprises a frame, a cab body structure and a hydraulic turnover mechanism, the cab body structure is hinged to the upper side of the frame, the hydraulic turnover mechanism comprises a manual oil pump, a hydraulic oil cylinder and a hydraulic lock, one end of the hydraulic oil cylinder is hinged to the frame, and the other end of the hydraulic oil cylinder is hinged to the cab body structure. A first oil way is connected between the oil pump and the hydraulic oil cylinder so that the hydraulic oil cylinder can drive the cab vehicle body structure to turn over. The hydraulic lock is fixed to the cab vehicle body structure, the frame is provided with a lock catch which is matched with the hydraulic lock in a locking mode when the cab vehicle body structure is horizontally arranged, and a second oil way is connected between the oil pump and the hydraulic lock and extends along the outline of the cab vehicle body structure. The second oil way and the cab vehicle body structure are designed in a shape-following mode, the oil way of the hydraulic lock can be arranged on a cab of various vehicle types in the mode, the oil way of the hydraulic lock does not need to be specially designed, and universality is better.
Description
Technical field [0001] The present invention relates to the field of cabling techniques, and more particularly to a suspension structure of a cab. Background technique [0002] In the freight car, especially large flat trucks, normally use the cabling design (or suspension design), and the hydraulic mechanism is used to drive the cab forward, in order to facilitate maintenance of the power device such as the engine. [0003] If the application announced the number of CN106741225A, a Chinese invention patent application published for 2017.05.31 discloses an intelligent cab transiscation system, and the flip system is disclosed, and the flip system is mounted between the frame and the cab, including the electric pump, Manual pump, hydraulic cylinder, fuel tank, hydraulic lock and limit device, an oil supply port connecting the oil tank, the oil port is connected to the manual pump, the outlet of the manual pump is connected to the hydraulic cylinder and the hydraulic lock, The hydr...
