How does the torque of a gear change?
A gear’s transmission torque changes as it increases or decreases speed. Generally, by reducing the speed, a small torque at the input side is transmitted as a larger torque at the output side. The calculation of torque depends on the number of teeth. Let me explain with a diagram using pitch circle diameters.
Why does my car keep fluctuating in rpm?
Do to the fact the transmission operation is somewhat temperature depending, it makes sense that there are internal transmission problems or Torque converter issues, though torque converter issues are fairly rare on the Gas engines. On the TDV6 it is common, although they use the same transmission they use a different torque converter.
Is it possible to increase rpm without decreasing torque?
1. Increase torque (not possible & its a design constraint) 2. Increase RPM without decreasing Torque (this is my thought but not sure how) 3. Quit (I am not gonna quit) Not sure though if I got it correctly. Please help. I am open to make changes if you suggest any to resolve this problem. You cannot convert 113 kW into 4000 kW with a gearbox.
When do the RPMs go up or down?
For example, RPM’s quickly move from 1,250 to 1,500 at 45 MPH. This problem has been ongoing for two years (and driving me a bit mad). The condition is most pronounced when traveling between 15 and 45 MPH. I’ve never once noticed the condition at highway speeds (above 55 MPH.
Why does my car rpm run so high?
When your car RPM is running high, it causes rough idling which means your engine may shake or vibrate while it is running. Your driving experience will not be comfortable. There are many reasons why the RPMs might be running high. The first thing to do is to check for bad spark plugs.
Why does my torque converter make a noise when I drive?
Since the torque converter pump, stator and turbine spin freely without engagement during neutral or park, the noise will not be present in those settings. Accelerate slowly in drive and listen to whether the torque converter noise will get quieter as the vehicle moves forward. Place your foot on the brake with the engine in neutral and idling.
When does the RPM go back to normal?
The RPM will usually go back to normal as you accelerate the vehicle, but will increase again after you stop. This is definitely not a normal situation. If you are experiencing a rough idle or your RPM is running high, then there are a variety of reasons for why this could be happening.
What causes a car to Rev in 5th gear?
What might cause a car with a manual transmission that in 5th gear when given a punch of gas revs to very high rpms – with no power transferred to the wheels (i.e. the tachometer and speed go out of sync).
