ENGINEERING

Designed with CAD and FEA, all structural parts are CNC precision laser cut stainless steel. The pedals are strong, stiff, compact and durable. Mathematical models were made to calculate pedal travel and operating force, predicting with great accuracy how each pedal feels in all of its many different configurations. Design tolerances have been optimized in order to have a minimal amount of unnecessary play.

All stainless steel metal profiles are bead blasted with glass beads before assembly. This results in a high quality semi-gloss metallic look with a minimum of sharp edges.

Load cells measure throttle and clutch position and brake pressure. Unlike designs with rotary potentiometers, load cells provide true linear output in relation to your pedal input. Their accuracy and durability are unmatched as they do not wear over time.

Custom developed 12bit USB electronics make sure each pedal responds instantly and accurately in your favorite simulator software. Travel is adjustable from 10° to 20° on the throttle and from 14° to 24° on the clutch. All end stops are ‘soft’ for a quality and neighbor friendly sound and feel.

HYDRAULIC DAMPING

The Sim Pedals Ultimate are a full-hydraulic pedal set: All 3 pedals feature an adjustable hydraulic damper. As pedal assemblies in real cars have hydraulic flow through hoses, tubes and cylinders, we use these to simulate the damping effect that these assemblies normally provide.

The brake and the clutch both feature a 2-way damper. This damper adds resistance depending on how fast the pedal is pressed or released. The throttle pedal features a damper which resists speed at the ingoing stroke. This helps with smoothing the throttle application and it is also used on some real race cars for this purpose. The resistance of all dampers can be adjusted.

The hydraulic system of the Sim Pedals Ultimate has proven to be ultra-reliable and does not require periodic maintenance. Even in the unlikely case of a failure, all hydraulic dampers can easily be removed while the pedal still retains its basic functionality as the pedal sensors are separated from the hydraulic circuit.

COMPONENTS

Throttle

Smooth, accurate and greatly adjustable, the throttle pedal gives you excellent control with exactly the travel, pre-load and spring stiffness you prefer.

Brake

The dual stage brake system consists of an initial coil spring, simulating the pad to disc gap and progressive rubber springs. The pedal firmness is adjusted by selecting from 10 different rubber stack heights. With 136kg or 300lbs max force, this pedal easily requires 36x more effort than regular consumer grade brake pedals. Braking using muscle memory improves accuracy and consistency.

Clutch

Clutch pedals often get lighter towards the end of their travel. The Heusinkveld Sim Pedals Ultimate feature a regressive spring mechanism allowing you to greatly adjust the effort, travel and feel. The maximum pedal effort of 45kg or 100lbs is again far greater than that of regular consumer grade pedals, but lighter settings are easily selected.
