The invention discloses a door type axle system which comprises a door axle inner shell, a door axle outer shell covers the door axle inner shell, a first gear used for being connected with a transmission shaft and a hollow second gear are arranged between the door axle inner shell and the door axle outer shell, and the first gear is meshed with the second gear through two third gears. The first gear, the second gear and the two third gears are arranged in a cross shape, a protrusion with an annular section is connected to the outside of the door bridge outer shell, the transmission end of the second gear extends out of the protrusion, and a through hole matched with the first gear is formed in the door bridge inner shell. An axle is arranged in the second gear and extends out along the through hole; the outer side walls, close to the second gear, of the door bridge inner shell and the door bridge outer shell are connected with positioning pieces, and the outer side walls of the positioning pieces are connected with supporting arm buffers matched with wheels. Under the same input power, higher output power can be provided, and the working efficiency is improved; and the trafficability and the dynamic property of the vehicle can be greatly improved on the premise that the running and turning stability of the vehicle is not reduced.
本发明公开了门式车桥系统,包括门桥内壳,门桥内壳上盖设有门桥外壳,门桥内壳和门桥外壳之间设置有用于连接传动轴的第一齿轮、中空的第二齿轮,第一齿轮通过两个第三齿轮与第二齿轮啮合,第一齿轮、第二齿轮及两个第三齿轮呈十字形排列,门桥外壳外连接有截面为环形的凸起,第二齿轮传动端伸出凸起,门桥内壳开设有第一齿轮适配的通孔;第二齿轮内设置有车轴,车轴沿通孔伸出;门桥内壳、门桥外壳靠近第二齿轮的外侧壁连接有定位件,定位件外侧壁连接有与车轮相适配的支撑臂缓冲器。在相同输入功率下,可以提供更大的输出功率,提高了工作效率;不降低车辆行驶与转弯稳定性的前提下,能大幅提高车辆通过性与动力性。
