AI Technical Summary
Technical Problem
In the prior art, when the drive axle assembly switches between neutral and gear, the tooth ends of the gears are prone to contact, resulting in low meshing power and affecting vehicle driving.
Method used
A guide surface is provided on the gear teeth. When the gears come into contact, the guide surface generates a force that causes the gears to rotate relative to each other, thereby improving the meshing efficiency.
Benefits of technology
By setting guide surfaces on the gears, the success rate of gear meshing is improved, ensuring smooth switching of the drive axle assembly between different states and enhancing the vehicle's driving performance.

Abstract
This application discloses an outdoor work vehicle, an outdoor lawnmower, and a drive axle system. The outdoor work vehicle includes: a frame with a drive motor and drive wheels; and a drive axle assembly connecting the drive motor and drive wheels. The drive axle assembly transmits the driving force of the drive motor to the drive wheels. The drive axle assembly includes a drive axle housing and two meshing gears located within the drive axle housing. At least one gear has a guide surface on its teeth. One of the two gears can move closer to or away from the other. When one gear moves towards and contacts the other gear, the guide surface of one gear abuts against the teeth of the other gear, generating a force that causes the two gears to rotate relative to each other. The outdoor work vehicle of this application can improve the meshing power of the two gears in the drive axle.
