前轴好象是不同油车间主要区别,目前主要有差速，直轴，单向三种. 不知道几种传动功能上有什么区别,各有什么优缺点?

前差速
Using a front differential combines some of the braking advantages of the solid front axle
while allowing inner-outer wheel speed difference.
A front differential is most commonly used in low grip conditions. It can improve onpower
corner entry as well as braking. The front differential is most commonly used with
the rear differential.
On very high traction surfaces, both front and rear diffs can be adjusted tighter for better
response

前差速鬆緊關係
Tighter
• Decreased steering response.
• More stability under braking, but less turn in.
• Better on power steering at corner exit.

Looser
• Increased steering response.
• Less stable under braking but better turn in.
• Car will understeer on power at corner exit.



前直軸
A front solid axle is typically used on large open outdoor tracks, or tracks that feature
braking areas or slippery (low traction) conditions. A front solid axle increases on-power
steering, and allows the car to brake using all four wheels. This lets you brake much later
than if you were using a front one-way axle (which would give rear wheel braking only).
Overall, using the front solid axle makes the car quite easy to drive.
The drawbacks of a front solid axle are less off-power steering, and the car becomes
more sensitive to tire diameter differences. To compensate for these effects, changes can
be made to the suspension (for example, roll center, front spring rate and/or dampening,
shock position, or caster).
A solid front axle is recommended for use with a rear ball differential. For maximum braking
effect, use the front solid axle with a solid central layshaft. Using this configuration, the
car achieves maximum 4WD braking, while being very stable and easy to drive.



前單向
A front one-way axle is a solid axle with
two one-way bearings at each end to which
each front wheel attaches. The front oneway
axle combines the characteristic of a
solid axle and a differential.

前單在加油收油;彎中出彎;煞車時的特性
On-power Mid-corner &corner exit
• Behaves like a solid front axle.
• One-way bearings lock up, causing both front wheels to spin at
same speed.
• Introduces some on-power understeer.

Off-power &braking :Corner entry &mid-corner
• Behaves more like a differential.
• One-way bearings disengage, allowing front inner and outer
wheels to rotate independently and at different speeds.
• No front braking.
