Drawings
FIG. 1 is a schematic illustration of a cab suspension control valve and hydraulic lock lockout;
fig. 2 is a schematic diagram of cab suspension control valves and hydraulic locks unlocking.
In the figure: the device comprises a control valve 1, a contact 1.1, a driven lock hook 2, a driving lock hook 3, a torsion spring 4, an oil cylinder assembly 6 and a hydraulic lock bolt assembly 5.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-2, a suspension locking mechanism with a control valve for a cab comprises a suspension pneumatic control system, wherein the suspension pneumatic control system comprises a hydraulic lock plunger assembly 5, a panel of the hydraulic lock plunger assembly 5 is provided with a driving lock hook 3, a driven lock hook 2 and an oil cylinder assembly 6, the driving lock hook 3 and the oil cylinder assembly 6 are arranged on the panel at the same side, the driving lock hook 3 is hinged above the oil cylinder assembly 6, a piston rod of the oil cylinder assembly 6 extends out, the top end of the piston rod is in contact with the driving lock hook 3, a torsion spring 4 is arranged between the driving lock hook 3 and the hydraulic lock plunger assembly 5, and the driven lock hook 2 is hinged on the panel opposite to the installation position of the driving lock hook 3; the suspension air control system is internally integrated with a control valve 1, the control valve 1 is installed on the side face of a panel of a hydraulic lock bolt assembly 5, and a contact 1.1 of the control valve 1 corresponds to the driven lock hook 2.
The control valve is a mechanical control valve which is simple to control and low in cost.
In the embodiment, referring to a schematic diagram of the cab suspension control valve and the hydraulic lock of fig. 1, the cab suspension control valve and the hydraulic lock are locked in working postures when the commercial vehicle is in running or parking.
