[0014] See Figure 1-7As shown, the present invention discloses a skid steer loader wheel-side electric drive device mounting structure, including a U-shaped channel plate 1 and a pair of side fixing plates 2. The U-shaped channel plate 1 is fixed at the bottom middle position of the vehicle body 3. The opening of the U-shaped channel plate 1 faces upward and can accommodate wiring harnesses and other components. Reinforcing plates can be provided on both sides of the opening of the U-shaped channel plate 1 to facilitate connection with the side fixing plates 2 and improve connection reliability and structural strength. A pair of side fixing plates 2 are symmetrically distributed on both sides of the U-shaped channel plate 1, and the side fixing plates 2 are fixedly connected to the vehicle body 3. Each side fixing plate 2 is fixedly installed with a side large flange seat plate 4. Both ends of the side large flange seat plate 4 are provided with mounting holes 6 for mounting the wheel-side electric drive device 5. Multiple bolt holes 7 are provided on the outside of the mounting holes 6 to realize the installation and fixation of the wheel-side electric drive device 5. Four semi-circular clearance grooves 8 are provided on the top of the U-shaped channel plate 1 and the side fixing plates 2. The position of the clearance grooves 8 corresponds to the position of the mounting holes 6 to avoid interference between the U-shaped channel plate 1, the side fixing plates 2 and the wheel-side electric drive device 5. A semi-circular protective cover 9 is fixedly installed between the side large flange seat plate 4 corresponding to each mounting hole 6 and the U-shaped channel plate 1. The U-shaped channel plate 1, side fixing plate 2, side large flange seat plate 4, and protective cover 9 form a receiving cavity 16, ensuring that the wheel-side electric drive device is installed without interference, and that there is sufficient space for motor wiring, sufficient space for motor heat dissipation, and that the rigidity and strength of the supporting vehicle structure are met. The opening of the protective cover 9 faces upward, serving to protect the wheel-side electric drive device 5. Each protective cover 9 has multiple heat dissipation holes 10 at its bottom to facilitate air circulation and heat dissipation. Each protective cover 9 has V-shaped protective plates 11 fixed on both sides below, which cover the bottom of the heat dissipation holes 10, but air can flow between the two protective plates 11 and between the two ends of the protective plates 11 to ensure heat dissipation and prevent foreign objects from entering.

[0015] The installation structure of this utility model uses a U-shaped groove plate 1, a side fixing plate 2, and a side large flange seat plate 4 to support and install the wheel-side electric drive device 5. This can reasonably optimize the structural layout and reduce the space occupied. At the same time, the protective cover 9 with multiple heat dissipation holes 10 and the protective plate 11 are used to protect the wheel-side electric drive device 5, which meets the heat dissipation requirements and avoids the wheel-side electric drive device from being bumped or foreign objects from entering. It has the characteristics of high structural strength and good heat dissipation performance.

The diameter of the stop groove 12 is adapted to the width of the mounting flange of the travel reducer of the wheel-side electric drive device 5, and the bolt hole 7 is located in the stop groove 12. During installation, the mounting flange of the travel reducer is inserted into the stop groove 12, which serves to position the installation and also to provide radial restraint, reducing the shear stress of the bolts and effectively extending their service life.

[0017] Preferably, multiple through holes 13 are provided on the side flange seat plate 4 to facilitate the fixing and lifting of the vehicle.

[0018] Preferably, a continuous bending plate 14 that bends downwards and outwards is integrally formed on the top of the side fixing plate 2, which serves as a protective measure to prevent foreign objects from being thrown onto the vehicle body by the tires when walking.

[0019] Preferably, a connecting plate 15 is integrally formed at the bottom of the side fixing plate 2. The connecting plate 15 is perpendicular to the side fixing plate 2 and is fixedly connected to the U-shaped channel plate 1 and the protective cover 9, further improving the connection reliability between the side fixing plate 2 and the U-shaped channel plate 1 and the protective cover 9, and ensuring the strength of the entire installation structure. Some clearance space is provided on the connecting plate 15 to avoid interference problems.

[0020] Preferably, the bottom surface of the guard plate 11 is flush with the bottom surface of the U-shaped channel plate 1, so that the bottom height of the entire skid steer loader is consistent, avoiding the problem of easy scraping due to high and low settings.
