What does an anti dive kit do?
Anti-dive is a suspension parameter that affects the amount of suspension deflection when the brakes are applied. ... When this happens there is no suspension deflection due to braking and no visible brake dive. There is still load transfer onto the wheels, but the chassis does not pitch nose down.Mar 1, 2002
What is anti dive and anti-squat?
Anti-dive and anti-squat percentages are always calculated with respect to a vertical plane that intersects the vehicles centre of gravity. Anti-dive and anti-squat are percentages that indicate the level at which the front of a car dives under braking and the rear of a car squatting under braking.Aug 8, 2011
What is anti-squat car?
Antisquat helps the car gain more vertical load on the rear tires, not from its own mechanical effect, but by helping to keep the rear of the car higher. Moving the third link laterally will allow you to determine where the added load will be applied between the rear tires.Jun 1, 2004
Is anti squat good or bad?
A system that doesn't combat any of the squat from the load transfer is going to result in unwanted suspension compression and you bobbing your way up a climb. Anti-squat is a good thing then, to combat the natural want of the bike to squat and compress the suspension.Mar 20, 2020
What is rear anti squat?
Anti-Squat is best described as Caster for the rear wheels…it changes the relation of the inner hinge pins parallel to the ground. The more anti-squat the vehicle has, the less the suspension will squat during acceleration. ... Adding Anti-Squat will make the car Squat less during acceleration.
How can I improve my anti squat?
By raising the front of the hingepin or lowering the rear, you are increasing the degrees of anti-squat. Typically, changes are made by either swapping out the rear suspension hingepin mount or by inserting shims under the front or rear of the mount before tightening down the mounting screws.
What is anti squat motorcycle?
Anti squat. The anti squat of a motorcycle is caused by the swing arm suspension system. The rotational point of the swing arm is above the point where the motorcycle drives itself (the ground!). This height difference and the driving force will create a torque that tries to push the rear suspension out.
What is anti squat MTB?
Anti-squat is the reaction of the rear suspension to the chain force. This means that the design of the suspension plays a role, but also the position and direction of the chain. The upper chain-line is key in the design of suspension.Feb 3, 2019
Why do cars lift when accelerating?
A car is shaped like an airfoil (like a wing of a bird or plane). As the car accelerates the air moves faster around it and you get a vertical force that lifts it from the ground. As the uplifting force increases, it reaches a point where the force of gravitation gets negated and the tip of the car gets lifted up.
What is pro squat?
If the front of the pin is lower, it is "pro-squat." More anti-squat. More forward traction. Less “squat” (dropping of the rear end under acceleration) Less on-power steering.Jun 2, 2021
What is anti lift geometry?
Anti-lift geometry is used mainly on front wheel drive cars and four wheel drive cars. It works when an acceleration force is acting through the centre of gravity causing the front wheels to raise as the rear tries to squat due to the acceleration force acting on the centre of gravity causing the car to pivot.Aug 18, 2018
How is anti-dive designed into suspension?
- For the very common double A Arm suspension, anti-dive is designed into the suspension based on the angle of the A Arm mounting points when viewed from the side. These are shown as the dotted lines in the picture below.
What is anti-dive geometry?
- Anti geometry causes the forces to be taken by Suspension A-Arms (eg :- in Double wishbone suspension) .It does not change wheel loads on front and rear , it only affects the weight transfer during braking to be distributed between suspension arms and springs How to Draw and calculate Anti Dive ?
What are typical anti-dive values?
- Because high anti-dive values can "feel" strange, require more complex suspension designs, and cause "rattling" type noises, typical values are in the range on 0-50%. We have 5 programs that work with Anti Dive when conducting Suspension Simulation.
Do anti-dive shocks need maintenance?
- The same is the case with the anti-dive shocks here as well. Since there are chances of air entering the system overtime just like in disc brake systems, there is a need of periodically maintaining the system which is not much work actually and it quite a simple task.
How to use anti-dive front suspension?How to use anti-dive front suspension?
Anti-Dive Front Suspension can be used to limit this characteristic. This can be achieved by tilting the upper front Control Arm (A Arm) so the rear mount is lower than the forward mount. For this vehicle I have made the following assumptions: The Centre of Gravity (CofG) of this vehicle is 600mm above the ground
What happens if your anti dive is too low?What happens if your anti dive is too low?
Suspension systems with anti-dive values under 100% will cause the front suspension to compress under breaking, often called nose-dive. Under acceleration, a low anti-dive geometry will cause the front end to lift and the suspension to extend which also shifts weight to the rear of the vehicle.

What are anti-dive shocks?What are anti-dive shocks?
So to counter this, manufacturers came up with the technique called anti-dive shocks which used the same principle of Bernoulli’s Principle in disc brakes to counter this system. The use of this was very simple.
