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 to 3, a sprocket box structure of a skid steer loader, a sprocket box body 2 is a cuboid structure, and the sprocket box body 2 is located on a frame center line. Four connecting plates 2-1 which are distributed in a rectangular shape are fixed on two sides of the chain wheel box body 2, and the connecting plates 2-1 are connected with the frame through bolts I1.
The two sides of the front end of the chain wheel box body 2 are respectively connected with a left front half shaft 7-1 and a right front half shaft 7-2 in a rotating mode, the two sides of the middle of the chain wheel box body 2 are respectively connected with a left motor 3-1 and a right motor 3-2, and the two sides of the rear end of the chain wheel box body 2 are respectively connected with a left rear half shaft 7-3 and a right rear half shaft 7-4 in a rotating mode.
The inner ends of the half shafts are positioned in the chain wheel box body 2, the inner ends of the half shafts are respectively provided with a large chain wheel 6, and the outer ends of the half shafts are assembled with the tire rim through bolts II 8 and drive the tire rim to rotate. The left motor 3-1 and the right motor 3-2 are fixedly connected with the chain wheel box body 2 through bolts III, the output ends of the left motor 3-1 and the right motor 3-2 are positioned in the chain wheel box body 2, and the output ends of the left motor 3-1 and the right motor 3-2 are respectively provided with two small chain wheels 4.
