Abstract
The invention relates to a large-oscillating-angle and great-movement-amount rear constant velocity driving shaft for an all-terrain vehicle. The rear constant velocity driving shaft comprises a wheel-end cardan joint, a differential-mechanism-end cardan joint and a middle shaft. The two ends of the middle shaft are each sleeved with a cardan joint outer sleeve. Steel balls are arranged between the side wall of the middle shaft and the inner wall of each cardan joint outer sleeve arranged on the middle shaft in a sleeving manner. The side walls of the two sides of the middle shaft and the inner walls of the two cardan joint outer sleeves are each provided with an arc-shaped ball channel for containing the steel balls. The side, close to each cardan joint outer sleeve, of the middle shaft is provided with a spring. One end of one of the cardan joint outer sleeves is connected with the wheel-end cardan joint, and one end of the other wheel-end cardan joint is connected with the differential-mechanism-end cardan joint. By means of the rear constant velocity driving shaft, the maximum oscillating angle and the maximum movement amount of the driving shaft are increased.
