All-New Suspension Designed for Superior On-road Performance and Durable Off-road Capability

Innovative Dynamic Handling System Improves Road-Gripping Abilities and considerably reduces physique roll

New Five-Link Rear Suspension for Maximum Control Both On- and Off-road

Engineers had been challenged with the duty of designing a Jeep® suspension that performs higher off-road, matches or surpasses present sturdiness and vastly improves automobile dealing with and experience consolation on-road. The answer: Combine the five-link rear suspension structure with an all-new Jeep Grand Cherokee impartial entrance suspension (IFS).

The all-new entrance suspension was designed for improved off-road efficiency and robustness. An unlimited enchancment in dealing with and experience consolation was achieved concurrently. The five-link rear suspension is tuned for excellent dealing with and stability in a bundle that’s simply as enjoyable and pleasurable to drive daily on the pavement as it’s off-pavement.

All-New Front Suspension and Steering Systems

An all-new short- and long-arm (SLA) entrance suspension offers glorious dealing with and experience traits whereas enhancing Jeep Grand Cherokee’s off-road efficiency.

Nodular iron, single-piece decrease management arms characteristic an L-shaped geometry designed to offer larger floor clearance on the wheels than most IFS methods. Forged higher management arms present energy and sturdiness. Tall aluminum steering knuckles present optimum steering and suspension geometry for glorious on-road dealing with and maneuverability. Gas-charged, twin-tube coil-over shocks ship high-performance management.

Front suspension journey is elevated by nearly 10 % (a couple of inch) in comparison with the 2004 Grand Cherokee, additional enhancing the 2005 Grand Cherokee’s off-road functionality.

The benefits in utilizing this uniquely designed entrance suspension embody a lot improved dealing with, lowered head toss on and off highway for a extra comfy experience, a financial savings of 100 kilos of unsprung mass for additional enchancment in experience high quality, extra exact steering and a decrease heart of gravity.

The 2005 Grand Cherokee rear suspension builds on the success of earlier technology Jeep multi-link methods. Four tubular management arms mix with a tubular monitor bar for whole rear-axle management. The shock absorbers (gas-charged, twin-tube) are positioned extra vertically than in previous fashions for higher physique management and lowered head toss.

The spring charges and shock dampening have been tuned to enrich the entrance suspension for a extremely balanced chassis.

Grand Cherokee’s new rack and pinion steering system imparts a extra exact steering really feel translated to the driving force by means of fewer linkages than a recirculating ball steering system.

Dynamic Handling System (“DHS”)

Note: This characteristic was initially scheduled to be accessible throughout the latter a part of the 2005 mannequin yr however was delayed and didn’t seem on any 2005 fashions. DHS was then deliberate for the 2006 mannequin yr but it surely now seems, as of knowledge acquired August 2005, that it has been placed on maintain as soon as once more and will NOT seem on any 2006 fashions.

The progressive Dynamic Handling System (DHS), developed by Delphi, makes use of a hydraulic-controlled lively stabilizer bar to reduce the standard compromise between experience and dealing with. Traditionally, a stiff stabilizer bar improves dealing with, however diminishes experience high quality. The Jeep DHS overcomes this by successfully decoupling the entrance and rear stabilizer bars besides when they’re wanted to enhance cornering efficiency. The essential benefit of the Dynamic Handling System is its capability to cut back roll bar forces underneath regular driving situations and highway impacts, whereas making use of solely the required roll bar forces to take care of as much as zero physique roll angle in corners.

The DHS responds in real-time to precise or anticipated driving situations. The lively system consists of hydraulic actuator cylinders that work together with the anti-roll bars, an influence supply, a management manifold with integral valves and a stress sensor, a controller and on-board automobile sensors which monitor steering angle lateral acceleration and automobile pace. The heart of gravity lateral accelerometers and higher lateral accelerometers are used to find out when the stabilizer bar is critical. Actuators pressurize the bar hyperlinks when the bar is required. While touring straight on-road, the actuators float and the bar can journey to the boundaries of the hyperlinks.

DHS delivers a excessive degree of driver confidence by considerably lowering physique roll in tight turns, leading to sportier dealing with and maneuvering, whereas offering a smoother experience when touring straight forward. Improved wheel articulation is one other benefit. Helping present fixed tire contact with the highway floor, DHS considerably will increase off-road functionality and driver consolation.
