[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0022] Please refer to Figures 1-6 , the embodiment of the present utility model provides a front axle drive device for a mechanical vehicle, including a housing 1, a brake disc assembly 2, an input shaft 5 and a transmission component 6. The transmission component 6 and the input shaft 5 are respectively movably connected to the inside and outside of the housing 1, and both ends of the transmission component 6 are drivingly connected with a steering assembly 3;
[0023] The housing 1 includes a right housing 11 and a left housing 12, and an O-ring 13 is placed between the right housing 11 and the left housing 12.
[0024] In this embodiment, there are two steering assemblies 3, and a flange 4 for mounting a tire is mounted on the side of each steering assembly 3.
[0025] In this embodiment, the transmission component 6 includes a differential 61. Both ends of the differential 61 are drivingly connected with a connecting shaft 62, and a bevel gear 63 is mounted on the side of the differential 61 through an involute spline.
[0026] By adopting the above technical solution, the protective sleeve provided on the right housing 11 covers the end of the left housing 12 to improve the structural strength of the connection part. At the same time, the installation groove provided at the end is used for installing the input shaft 5 to prevent damage to the front axle drive device after bumping, vibrating or being strongly impacted.
[0027] In this embodiment, the end of the connecting shaft 62 is movably connected to the differential 61 through a bearing, and the other end is movably connected to both ends inside the housing 1 through a bearing.
[0028] In this embodiment, the end of the input shaft 5 penetrates through the right housing 11 and the left housing 12 and is in driving cooperation with the differential 61, and the input shaft 5 is arranged on the side of the differential 61.
[0029] In this embodiment, a driving gear is fixed at the end of the input shaft 5, and the driving gear is in meshing transmission with the bevel gear 63.
[0030] In this embodiment, the steering assembly 3 includes two rotatable shaft heads and shaft seats. The shaft heads and shaft seats can rotate relative to each other, and a shaft rod penetrates between the shaft heads and shaft seats.
[0031] Among them, the shaft head is fixedly connected to the ends of the right housing 11 and the left housing 12, and the shaft seat is movably connected to the flange 4.
[0032] In this embodiment, two meshing transmission gears are provided at the end of the shaft rod. One transmission gear is fixed at the end of the shaft rod, and the other transmission gear is fixed on the side of the connecting shaft 62 away from the differential 61.

[0035] The working principle of the present utility model is as follows: when in use, first, through the transmission connection between the driving gear and the bevel gear 63, the input shaft 5 drives the transmission assembly 6 to rotate, and the power is transmitted to both sides respectively through the cooperation of the differential 61 and the connecting shaft 62. The connecting shaft 62 drives the shaft rod in the steering assembly 3 to rotate through two meshing transmission gears, and the steering is realized through the shaft head and the shaft seat in the steering assembly 3. Moreover, the other end of the shaft rod transmits the power to the output shaft through the bevel gear, realizing the power transmission while steering.
