i have to design an actuation system which will change the angle with which the power is transmitted through a motor,the range of angle is about,--35 to +35,w.r.t to the vertical,what should i use,a u joint or a velocity joint?there is a predefined load on the shaft(bending + torsional),what should i use?
i have on other option to use a hub motor to deliver power,that will eliminate most of the complexities,but i am not sure whether a hub motor is capable of withstanding minor shocks,and bending stresses.

I am not a Mechanical Engineer but I think you would need to specify a few values before you can expect an answer. So far the answer must be "It depends", I think.

The range of motion for your application is pretty large. Universal joints are best used when the range of motion is only a few degrees; with larger angles, they can freeze up and they will experience higher wear and shorter life than a comparable CV joint.
