Abstract
The invention discloses a propeller folding device, which comprises a transmission upper box, a transmission shaft outer cylinder, a transmission lower box, a propeller, a mounting frame, a sleeve, a positioning seat, a short shaft, a rotating arm, a hydraulic cylinder, a hydraulic cylinder seat, a steering The rudder, steering rudder seat, bushing, cable and bolts, among which the transmission upper box, the outer cylinder of the transmission shaft and the transmission lower box are fastened together by bolts, and the propeller is fixed on the output shaft of the transmission lower box. The rotation and folding of the propeller can be realized, and the steering rudder can be controlled by the cable to realize the steering on the water surface. This device has scientific design, compact structure, reliable performance, convenient loading and unloading, and low cost. Surface floatation provides ideal power and reliable steering.
Description
technical field [0001] The invention relates to a general hydraulic mechanical device, in particular to a propeller device which can provide power and reliable steering when the vehicle floats on the water surface, and is installed on the rear of the vehicle in a folded manner. Background technique [0002] At present, the amphibious vehicles manufactured both at home and abroad are equipped with fixed propellers and are all installed under the vehicle floor. Although this assembly method is simple in structure, it significantly reduces the ground clearance of the vehicle, thereby obviously affecting the passing performance of the vehicle on land, and its propeller is also prone to damage. Contents of the invention [0003] The purpose of the present invention is to provide a "propeller folding device" that is scientific in design, compact in structure, reliable in performance, convenient in loading and unloading, low in cost, and can be matched with various amphibious veh...
