Described drive axle is provided with forerunner's gear, and described rear drive shaft is provided with the rear-guard gear, and the rear-guard gear has two stations on rear drive shaft, is respectively the transmission station and breaks away from station; Described gear drive comprises first transmission shaft, idle gear axle and second transmission shaft that is located on the housing, described power input gear is located on first transmission shaft and is meshed with idle gear on being located at the idle gear axle, described idle gear is meshed with driving gear on being located at second transmission shaft, and described driving gear is meshed with described forerunner's gear; Be meshed with described driving gear when described rear-guard gear is positioned at the transmission station, described rear-guard gear is positioned at when breaking away from station and described driving gear is separated.
Being provided with of gear drive is simple in structure, is easy to make.Be meshed with described driving gear when the rear-guard gear is positioned at the transmission station, described rear-guard gear is positioned at when breaking away from station and described driving gear is separated, thereby rear drive shaft can outwards be exported or outputting power not as required.
Described power input gear is the high and low shift fixed gear, comprises big driving cog wheel disc and small transmission gear dish; Described small transmission gear dish is meshed with described idle gear; When the high and low shift sliding gear was positioned at high-grade position, described canine tooth wheel disc was meshed with described small transmission gear dish, and when the high and low shift sliding gear was positioned at low gear position, described small gear dish was meshed with described big driving cog wheel disc.
When the high and low shift sliding gear was positioned at high-grade position, described canine tooth wheel disc was meshed with described small transmission gear dish, thereby makes first transmission shaft have higher rotating speed.When the high and low shift sliding gear was positioned at low gear position, described small gear dish was meshed with described big driving cog wheel disc, thereby makes first transmission shaft have lower rotating speed.
In a word, the utility model is simple in structure, is convenient to make, and not only has the transfer function, has speed changing function again concurrently simultaneously, especially is fit to the tractor of bowing.
