Does a Larger or Smaller Truck Rear Axle Ratio Make It Faster?

[Yolanda]

In the same gear, a smaller ratio makes it faster. Different ratios cannot be compared. Here are the relevant details: I. Truck Rear Axle Ratio: 1. The rear axle ratio is actually called the "final drive ratio," not the "rear axle ratio." 2. The size of the ratio mainly depends on the vehicle's purpose. For long-distance high-speed logistics, a high-power, small ratio (below 4.444) is recommended. 3. For short-distance heavy loads and long-term harsh working conditions, a high-power, large ratio (above 5.73) is recommended. With the same displacement, higher power is better! II. For FR rear-wheel-drive models: Vibration and force analysis. Power is typically output from the engine crankshaft flywheel, passes through the clutch (which can only maintain a fixed ratio), and is transmitted to the transmission main shaft. The gearshift fork controls the synchronizer to switch between gears with different ratios, outputting to the transmission output shaft, universal joint, driveshaft, differential, axle shafts, and wheels.
