Description

2351051 Improved Vehicle Architecture The present invention relates to an
improved vehicle architecture for a front wheel drive vehicle.
There are many known vehicle architectures for front wheel drive vehicles. The principal architecture is the transverse engine front wheel drive configuration which will be 5 known to those skilled in the art.
However, there are a number of limitations to such a layout. It is difficult to obtain a satisfactory crash performance. Indeed, as customer expectations increase, legislation tightens and pressure for improved weight reduction and improved packaging grows, achieving satisfactory crash performance will become even more difficult.
Vehicle refinement is also adversely affected in such a layout due to the close proximity of the power unit to the vehicle bulkhead and the conflicting demands placed upon the engine/transmission mounts.
In addition, the weight distribution and variation due to changes in the vehicle payload together with the relatively high centre of gravity of the main mechanical components can be detrimental to handling, ride, braking and tyre characteristics.
Vehicles having a rear mounted powertrain and rear wheel drive have been proposed. Such an arrangement has an enhanced front crush zone. However, the power train mass must still be retarded by the front bodyshell and rear intrusion of the powertrain must be countered. Also, rear engine cars can suffer from nervous handling at high speeds, and in comparison with front wheel drive cars do not display "fail safe" handling characteristics. In addition such vehicles tend to lack luggage space.
Accordingly, there is a need for a front wheel drive vehicle which overcomes these problems while providing suitable crash, refinement and vehicle dynamic performance.
According to a first aspect of the present invention, an architecture for a motor vehicle comprises a driveshaft, a flat power unit mounted to the rear of the vehicle, and a flywheel, a clutch, ancillaries and a transaxle comprising a gearbox and differential unit mounted close to or forward of a front axle centreline of the vehicle. This has as an advantage that a front weight bias of between 50% to 65%, more preferably 55% to 60%, can be maintained. This provides for satisfactory handling, traction and stability in a motor vehicle adapting the vehicle architecture of the present invention.
Prefdrably, the driveshaft comprises shafts running longitudinally through extension casings connected centrally by a single universal joint. This has as an advantage that the casings can transfer load between the front and rear of the layout. Further, the universal joint enables relative movement of the power unit and the gear box.
Preferably, an input shaft to the flywheel passes through a primary gear cluster of the gearbox to drive the flywheel which transmits drive back to the clutch and then into the primary gear cluster. More preferably, power assisted steeringlair conditioning pumps, an alternator, a starter motor and a battery can be mounted forwardly of a front axle centreline to maintain front axle loading of the motor vehicle. This also provides for a direct gearchange linkage. This has the further advantage of providing a reduced area presented to the bulkhead in crash, in particular in the areas of a steering column, plenum and footwell.
The invention will now be described, by way of example only, with reference to the accompanying drawings, in which; Figure 1 shows a perspective view of the main component layout for a vehicle architecture according to the present invention; Figure 2 shows a plan view of several of the components illustrated in Figure 1; Figure 3 shows a side view of the components of Figure 2 Figure 4 shows in section one embodiment of a drive assembly for use in the present invention.
Referring first to Figure I there may be seen an overview of the main technical elements 5 of a motor vehicle relative to one another.
A flat power unit 2 is shown disposed to a rear of the layout. A drive shaft shrouded by extension casings 6 extends from the rear of the layout to a front of the layout. A front axle 8 having a front axle centreline 10 is disposed to the front of the layout. A flywheel 12 and a drive 14 for ancillaries are shown mounted to the front of the drive shaft. A transaxle 16, comprisink a gearbox 18 and a differential unit 20, is mounted close to or forward of the front axle centrelinelO.
It will be noted that a clutch 28 and the flywheel 12 are mounted in line. This avoids the need for transfer gears, keeping gearbox synchro inertial loads to a minimum. This has consequential benefits in gearchange quality. This also makes forward mounting of a starter motor 30, battery and such practicable, thereby maintaining front axle loading.
The drive shaft comprises first and second shaft members 22,24 running longitudinally through the extension casings 6 connected centrally by a single universal joint 26. The drive shaft may be secured to the flywheel 12 by any suitable means. Conveniently, a taper joint and key, a spline joint, or parallel interference with a drive pin may be used.
The extension casings 6 may be formed as hollow units with bearings to support the first and second shaft members 22,24. Alternatively, the extension casings 6 may take the form of open inverted "U"-shaped casings with bearings to support the first and second shaft members (Figure 4). The relatively long extension casings 6 also have as an advantage that they provide a widely spaced, three point platform for the mounting of the power unit 2 and the gearbox 18. This has benefits in location, NVII and independence of tuning. Such mounting is typically by way of compliant mounts.
Providing a single centrally located universal joint 26 in the drive shaft reduces the drive shaft components and housings to a manageable size and allows independent tuning of the 5 shaft components, the position of the universal joint and chassis mounting system elements.
Moreover, the extension casings 6 act as a strut in the event of a crash. The rear mounted power unit 2 is retarded independently of a motor vehicle body structure to prevent intrusion of the power unit 2 into a rear of a passenger cell of a motor vehicle. Damage due to rear impacts is also reduced by this effect. This is a particular advantage for a vehicle with a short redr overhang, such as a small hatchback type vehicle.
The height of the power unit 2 may be minimised by using the waist of the power unit for intake 32 and exhaust 34 routes. Further advantages may be obtained by careful positioning of oil filters and other power unit mounted ancillaries.
By locating the power unit 2 to the rear of the layout advantages are obtained not only for crash performance in a vehicle to vehicle collision, but also due to the absence of a power unit, in the front of a vehicle adopting the layout of the present invention, pedestrian impact is much improved.
Further, the absence of the power unit from the front of the layout allows greater styling freedom for a front end of the vehicle. Also, the passengers and payload may be placed further forward in the vehicle than hitherto, thereby reducing variation in ladenlunladen weight distribution, without compromising crash performance.
Static, payload and dynamic weight distribution are fundamental factors in defining the ride and handling characteristics of a vehicle. This is particularly so as vehicle size decreases. The distribution of fixed masses at each end of the vehicle layout provides a p relatively high polar moment of inertia. This allows reduced pitch and lateral nervousness, improving ride and stability of the vehicle.
In addition, much of the NVI1 source is now located to the rear of the vehicle to a position inherently muffled from vehicle occupants since the NVH source is now located 5 beneath or behind seating.
There is an increasing emphasis in modern vehicles towards improved side impact performance. A wide body and hence track/wheel arch would allow slight (approx. 50 mm) forward placing of seating positions. A higher seating position also improves crash behaviour, contribute to a feeling of control of the vehicle and increase space available for a central under floor fuel tank. Together this places the centre of gravity of the payload as near as possible to a centre of a wheel base of the vehicle, thereby improving consistency of handling of the vehicle between unladen and laden conditions.
Since the ancillaries are located in a forward bay of the vehicle, access in the absence of the power unit 2 from this area is much improved. In addition this area of the vehicle is considered to be generally less hostile environmentally to the ancillaries.
The absence of the power unit 2 from the front of the vehicle also allows the possibility for a modest front luggage space to be considered.
The use of a flat, horizontal or substantially horizontal power unit 2 enables minimum intrusion into any rear boot space. In particular, the clutch/flywheel assembly 28,12, which by its nature is bulky, together with most of the ancillaries, are mounted at the front. This also reduces the profile of the power unit 2 should the power unit engage with a vehicle body-in-white during a crash event.
In addition, such a power unit 2 lowers the centre of gravity of the vehicle. A low centre of gravity provides improved handling, braking and roll characteristics.
The transaxle 16 configuration presents a comparatively small profile during a crash event until the clutch/flywheel assembly 28,12 is encountered. In other words, the gearbox 18 is sufficiently small to enable it to telescope into an adjacent extension casing.
The relatively large spacing from the clutch/flywheel assembly 28,12 to a bulkhead of a motor vehicle allows the clutch/flywheel assembly 28,12 to be driven down during a crash event with a relatively shallow trajectory. Further, the forward mounting of the clutch/flywheel assembly 28,12 delays intrusion during a crash event. The forward mounting of the clutch/flywheel assembly 28,12 also provides substantial forward mass with resulting good weight distribution.
Moreover, the forward mounting of the clutch/flywheel assembly 28,12 also provides for a convenient drive take off for the ancillaries, as well as convenient access to the clutch 28, and other components, for service and replacement.
The centrally mounted differential unit 20 allows long and equal length drive shaft members 22,24 with benefits in geometry and durability.
