The invention relates to the technical field of vehicle carrying, in particular to a screw propelling wheel connecting angle adjusting device. The device comprises a worm, one end of the worm is connected with a worm bearing seat through a worm bearing, and the other end of the worm is connected with a driving end of a servo motor through a coupler; a worm wheel is arranged on one side of the worm, spiral teeth of the worm wheel are connected with a threaded section of the worm in a meshed mode, and an internal threaded section of the worm wheel is connected with the surface of the lead screwin a threaded meshed mode; one end of the lead screw is rotationally connected to one end of the adapter plate through a first pin shaft, the other end of the adapter plate is jointly and rotationallyconnected with ends of the two guide rods through second pin shafts, and the other ends of the two guide rods are inserted into blind holes in ends of spiral propulsion wheels. The connecting angle of the spiral propelling wheels is changed by adjusting the height of the middle connecting position of the two spiral propelling wheels on the same side so that the ground contact area is increased, the middle portions of the spiral propelling wheels are prevented from sliding in a suspended mode, the climbing capacity is improved, and safety accidents caused by the fact that a screw propelling vehicle rapidly turns over at the ridge can be avoided.
本发明涉及车辆运载技术领域,尤其是一种螺旋推进轮连接角度调整装置。其包括蜗杆,所述蜗杆一端通过蜗杆轴承连接蜗杆轴承座,蜗杆另一端通过联轴器连接伺服电机的驱动端;所述蜗杆一侧设有涡轮,所述涡轮的螺旋齿和蜗杆的螺纹段啮合连接,所述涡轮的内螺纹段和丝杆表面螺纹啮合连接;所述丝杆一端通过第一销轴转动连接在转接板一端,转接板另一端通过第二销轴共同转动连接两个导杆的一端,两个导杆的另一端插接在螺旋推进轮一端的盲孔中。本发明通过调整同侧两螺旋推进轮中间连接处的高度,改变螺旋推进轮的连接角度,以此增大触地面积,防止螺旋推进轮中间部分悬空打滑,提高了爬坡能力;能够避免螺旋推进车在山脊处迅速翻转引发的安全事故。
