2002 Volvo S60 AWD

2002 Volvo S60 AWD At its creation, the Volvo S60 become defined as the Swedish manufacturers' sportiest and maximum dynamic sedan...Ever. The next degree within the employer's commitment to improved riding satisfaction is now available - the Volvo S60 AWD - the first Volvo with electronically managed all-wheel-power.

Electronically-Controlled All-Wheel Drive

The Volvo S60 AWD capabilities electronically controlled AWD. The Active-On-Demand (AOD) system has been advanced in collaboration with one of the pioneers in this area - the Swedish corporation Haldex. In this new gadget, the electricity is shipped between the front and rear wheels through a moist multi-plate take hold of.

The characteristic of this specific design is divided into three components: hydraulic, mechanical, and digital systems.

The unit can be regarded as a hydraulic pump that when a pace distinction between the front and rear wheels takes place, a hydraulic pump generates oil strain that forces two sets of wet take hold of plates to close. When both axles are rotating on the identical pace, strain is decreased bringing the pressure wheels into equilibrium.

As it is a mechanical piston pump, the response is really on the spot - approximately 15"" of wheel rotation, without any delay occurring as a result of slow pumping.

The device is electronically controlled through a module installed at the rear differential. It bureaucracy part of a unit with the stepper motor and the manipulate valve. The differential digital module communicated with the Engine Control Module (ECM) and brake manage module thru the Control Area Network (CAN). The differential digital module uses sensor indicators to manipulate oil pressure at the wet clutch plates with the aid of adjusting a manage valve.

The oil stress on the wet grab plates determines the torque that can be transferred to the rear wheels in which the housing and the hoop-shaped piston are connected to at least one axle even as the piston manipulate unit is attached to the alternative axle. When each axles are rotating at the same pace, no pumping takes place. As quickly as a difference in velocity arises, the pumping and go with the flow of oil starts offevolved.

Oil is furnished to a grab piston which compresses the moist snatch percent consequently reduces the velocity distinction. The oil returns to the reservoir thru an adjustable throttle valve, which controls the oil stress, and consequently the pressure at the wet clutches.

The electronic manage method that the take hold of capability may be tailored to different riding situations.

Intelligent System

The AWD device is electronically clever. It senses what avenue condition (through avenue wheel slippage) and what the driver wants. This records affords the basis for whether or not and the way the system is to act.

When accelerating on a tough surface, as an example free gravel, rapid effective and on the spot engagement takes vicinity. During a low speed cornering or parking maneuver, the gadget knows that the distinction in speed among the wheels does no longer require engagement - and as a result, the inertia skilled with different systems in comparable situations is averted.

The AWD machine is hooked up to the car Multiplex electrical system. As a result, it communicates with the other structures within the vehicle on the way to optimize all-wheel drive to healthy nearly any driving scenario. This digital conversation includes the Traction Control System (TRACS), as an example.

Beginning January 2002, it'll additionally be feasible to equip the Volvo S60 AWD with DSTC (Dynamic Stability and Traction Control) for better skid control in the course of destructive weather conditions.

Lightning-Fast Engagement And Disengagement

The electronically managed AWD machine is characterized first and main by means of its extremely speedy engagement and disengagement instances, a similarly illustration of Volvo Cars' commitment to driving safety.

"The pace of the machine offers what became already a properly-balanced automobile highly suitable street coping with. After all, the owner of a sedan does now not use all-wheel drive normally for accessibility but for most beneficial roadholding and balance," says Hans Gustavsson, Senior Vice President Research, Development & Purchase at Volvo Car Corporation.

Five-Cylinder Turbocharged Intercooled Engine Developing 197hp

The Volvo S60 AWD is geared up with a five-cylinder, 2.Four-litre engine with a light-pressure turbocharger. Output is 197 hp at five,one hundred rpm and maximum torque is 210 lb./ft. At a low 1,800 rpm.

This engine is also used within the Volvo S60 2.4T. It is a member of the brand new technology of RN engines, which have undergone enormous modifications to lead them to cleanser and greater gas-efficient.

Quick responding turbocharged engine management software program manner that the engine has a lightning reaction and remarkable power at low engine speeds -  very important functions in relation to the Volvo S60 AWD's dynamic traits.
