02 Rsx Front Suspension Diagram

Overview

The RSX chassis was designed to achieve quick handling response, outstanding grip, a smooth and compliant ride, excellent stability, and exceptional packaging efficiency to help maximize spaciousness in the passenger cabin and engine bay.

The RSX features a Control-Link MacPherson Strut front suspension design. This advanced design provides the precise handling, stability and comfort of a double-wishbone layout with packaging efficiency that is difficult to achieve with a conventional front double-wishbone design. At the rear, a highly compact double-wishbone suspension improves handling, ride comfort, stability, and space efficiency. Inversely wound front coil springs are applied to minimize the affect of suspension compression on steering precision. To deliver an even more high performance driving experience, the Type-S suspension features stiffer rear springs and more compression and rebound damping front and rear. Type-S models also have a strut tower bar to further increase body rigidity.

The RSX wears standard 205/55R16 all-season high-performance tires on 16x61/2-inch, five-spoke alloy wheels. The RSX Type-S gets enhanced traction with 17x7-inch alloy wheels and Michelin 215/45R17 high-performance all-season tires.

The braking systems on both models provide enhanced brake feel and superior performance. A rigid pedal and short stroke help to deliver an immediate-feeling braking response. Secure stopping power is provided by large-diameter disc brakes equipped with a standard Anti-lock Braking System (ABS). In front, the RSX wears 10.3-inch ventilated discs, while the Type-S uses 11.8-inch ventilated discs. Both models use 10.2-inch discs at the rear.

The RSX utilizes a torque-sensitive, rack-and-pinion power steering system that is tuned to provide quick steering response. A variable capacity power-steering pump provides greater hydraulic pressure and quick catch-up during aggressive cornering. A rigid steering column helps deliver in a solid steering feel.

Front Suspension

The front suspension of the RSX combines performance-tuned handling (including superb grip and responsiveness) with positive feedback and road feel, a smooth and fluid ride, excellent space efficiency, and a reassuring level of safety.

After analyzing these objectives, the RSX engineers designed a state-of-the-art Control-Link MacPherson Strut front suspension with performance comparable to a double-wishbone system. Compared with conventional strut designs, this design provides superior suspension geometry and control by adding a control link to precisely vary toe change throughout the suspension's travel. This suspension helps increase the front tire's contact with the road- enhancing handling performance and stability, particularly during sporty driving. For superb refinement, the layout incorporates low-friction progressive-valve gas-pressurized shock absorbers that more effectively absorb bumps and other road shocks.

The compact design of the Control-Link MacPherson Strut front suspension helps to maximize packaging efficiency, providing added room for the RSX's high-output engines and increasing the spaciousness of the cabin. This layout also provides advantages simply not obtainable with a conventional front double-wishbone suspension, including the ability to incorporate a high-mounted steering gearbox. This arrangement uses high-mounted tie rods to steer the vehicle and provide improved toe control (the amount the tires angle in toward the body). The steering system also provides exceptional tracking stability during cornering.

Geometry and suspension settings have been optimized to give the RSX a low center of gravity, helping to reduce body roll and enhance stability. Spring and damping rates complement the suspension geometry.

To provide even more agile steering for the Type-S model, front damper bearings (where the strut mount attaches to the body) are used to decrease friction, allowing the wheels to turn more easily in response to driver input and thereby increasing steering feel.

On vehicles that utilize a strut front suspension design, since the strut is responsible for load bearing, drive forces during the suspension's compression stage can sometimes influence steering precision. As the springs compress, they exert torsional force in the opposite direction on the steering mechanism and sometimes make the car pull to the side. To neutralize this affect, Acura applied inversely wound (wound in the opposite direction) coil springs to the front struts. As the two front springs compress in opposite directions, the torsional forces they produce cancel each other out, minimizing their affect on steering.

Rigid stabilizer bars are applied on both models to reduce body roll during cornering. On the RSX, the diameter of the front stabilizer bar is 25.4 mm and the wall thickness is 3.0 mm. Front stabilizer bar diameter on the Type-S is 26.5 with a wall thickness of 3.5 mm.

A strut tower bar on Type-S models minimizes body flex and enhances traction during cornering.

Rear Suspension

The RSX features a compact double-wishbone suspension designed to provide excellent handling, ride comfort, stability, and space efficiency. The geometry of this suspension arcs the tires rearward when compressing over bumps to reduce road shock and provide a smoother, more comfortable ride. By optimizing the rigidity of the body, bearings, control arms, and stabilizer bar, the rear suspension provides secure tire-to-ground contact for smooth, predictable handling. Rear toe-in during braking helps improve the vehicle's stopping stability.

At the same time, this highly compact design uses less space than conventional double-wishbone systems because there is no trailing arm alongside the fuel tank. Freeing up space in this manner allowed the engineers to place the exhaust pre-chamber in the rear- instead of in the cabin floor, enabling them to design a wider trunk and a flat floor in the interior.

Rear spring and damping rates have been tuned to deliver an exacting combination of handling and ride comfort. The spring rate of the bushings at the suspension mounting points minimizes vibration without compromising suspension rigidity. The diameter of the rear stabilizer bar is 21 mm, which helps provide increased road-holding capability.

Steering

The RSX uses a torque-sensitive, rack-and-pinion power steering system equipped with a variable-capacity power-steering pump. By incorporating a relief valve, which adjusts necessary power assist through oil-quantity control, the pump is able to achieve a linear volume. Unnecessary oil flow at 900 rpm and above is eliminated resulting in improved fuel economy. The pump flow creates increased hydraulic pressure and allows the steering to better "catch-up" during aggressive slalom-type driving. A kickback reduction valve reduces steering kickback when driving over bumps or objects in the road.

A quick steering ratio (14.9) allows for nimble handling and this ratio, combined with the stabilizer bars also enhances turn in. The reinforced steering column increases stiffness for a solid steering feel.

The high-mounted steering box improves tracking stability and toe control (the amount the tires angle in toward the body) by using long, high-mounted tie rods to steer the vehicle. An oil-filled damper on the steering box reduces vibration to provide steering smoothness and directional stability.

Braking System

For outstanding stopping power and excellent resistance to fade, the RSX is equipped with 10.3-inch ventilated front disc brakes and 10.2-inch rotors at the rear. On the Type-S, the ventilated front rotors are 11.8 inches in diameter.

A short pedal stroke gives the RSX a solid and linear brake feel. A large diameter master cylinder increases brake fluid displacement and enhance brake pedal feel.

Anti-Lock Braking System

Standard on both RSX models is a three-channel Anti-lock Braking System with a speed sensor located at each wheel. The system modulates braking power to the front wheels independently and to the rear wheels in tandem- enhancing driver control during maximum-effort stops.

Wheels and Tires

The RSX wears large wheels and tires in keeping with its race-bred, sports coupe breeding. The RSX features 205/55R16 Michelin MXM-4 all-season high-performance tires on strong, lightweight 16x61/2-inch, five-spoke cast-alloy wheels. The RSX Type-S comes with 17x7-inch alloy wheels and Michelin 215/45R17 tires.

Flat Floor

The unique flat floor of the RSX- made possible by the compact rear suspension and such innovations as a high-efficiency exhaust system- helps make the cabin remarkably spaciousness and comfortable. To improve the floor's torsional rigidity, the RSX uses a "tunnel side frame" with a large, flat cross-section instead of the usual tunnel structure.

Resin Fuel Tank

The RSX is equipped with a four-layer resin fuel tank that offers reduced weight, increased capacity, and reduced emissions. Capacity is maximized because the resin tank can be molded to fit around other components. The unique shape of the RSX fuel tank reduces fuel evaporation. This reduction lowered evaporative emissions, enabling the RSX to achieve a LEV2 rating. The RSX also incorporates a returnless fuel supply system that helps reduce vapor generation.
