jdfabs Posted June 9, 2015 Posted June 9, 2015 Can someone please explain what this: http://imgur.com/vL1qrhC Does exactly. in my thinking while not muth torque is needed the L motor would spin faster than the xl but when the torque becomes bigger the XL motor would "take over" giving it more strengh that the L motor alone Sorry if I'm wrong XD Quote
9v system Posted June 9, 2015 Posted June 9, 2015 From the looks of it. It apeers to be a coupler for combineing the powe of the two motors. I have seen something like this before. Quote
jdfabs Posted June 9, 2015 Author Posted June 9, 2015 (edited) From the looks of it. It apeers to be a coupler for combineing the powe of the two motors. I have seen something like this before. But L motor has more RPM and less torque and the XL motor less RPM and more Torque... i curently dont have those pieces to test what would actualy happen... would it be like the middle ground betwin both motors?

9v system Posted June 9, 2015 Posted June 9, 2015 I presume that it gives you the speed of the m motor with the torque of the xl motor Quote

Saberwing40k Posted June 9, 2015 Posted June 9, 2015 This assembly is technically an adder, which is also discussed in Sariel's book. Basically, it would split the difference between the speeds of the two motors. But, there are some problems. The motor is an M motor, not an L motor, neither motor is connected to the frame, and the 24z gear cannot mesh with the differential. An adder can also, at least in theory be used as a type of virtual gearbox. Quote
Captainowie Posted June 9, 2015 Posted June 9, 2015 (edited) Well, as far as those bits arranged in that fashion is concerned, all it'll do is make a lot of noise. Spur gears don't mesh at 90 degrees! Edit: Damn, beaten to the punch by Saberwing Edited June 9, 2015 by Captainowie Quote

Thanks for teh information I had already noticed the problems you refered. so that system can be used as a virtual gearbox: while on plain ground it would almost(?) have the speed of a L motor and while on a high ramp it would have the more powerfull XL motor Torque right? I'm so sorry about the ignorance about this and its tecnical terms i realy wanted to create a car that can be speedy as well strong when needed without an actual gear box... soo this theoreticaly would work right?

Actually, no. The way it works is that the motors have to be controlled independantly, and it would function like as follows. Let's call the motors motor A, and motor B. The adder system would have four modes: Motor A only Motor B only Motor A with motor B Motor A against motor B However, I have tried to implement a system like this, and failed. All too often, if the wheels on the vehicle got stuck, then the motors would merely drive each other. To do what you want, I'd recommend either an automatic gearbox, or a CVT. I have seen both ideas, but I cannot link to them right now. When I get to my computer at home, I'll post the links. Quote
