Abstract
ABSTRACT OF DISCLOSURE
Apparatus for a vehicle for electrical drive thereof comprising a removable unit beneath the vehicle floor carrying a removable battery pack an electric motor and transmission from the motor to wheels of the vehicle.
Apparatus for a vehicle for electrical drive thereof comprising a removable unit beneath the vehicle floor carrying a removable battery pack an electric motor and transmission from the motor to wheels of the vehicle.
Description
107~
This invention relates to electrically drive motor vehicles of the kind having a rechargeable battery pack and an electric motor which drives the vehicle through an appropriate reduction transmission.
The invention is principally directed towards vehicles which were originally designed for conventional internal combustion engine drive and particularly though not exclusively to goods vehicles.
In view of the fact that the battery pack has to be recharged from a source outside the vehicle and since the vehicle itself does not carry charging e~uipment, the principal use envisaged is for short journey goods vehicles.
It is the object of this invention to provide, for a vehicle, apparatus for electrical drive, the apparatus being particularly convenient for converting vehicles originally designed for conventional internal combustion engine drive.
Accordingly, the present invention provides an apparatus for converting a vehicle originally designed for conventional internal combustion engine drive into a vehicle having an electrical drive in the form of an add-on unit, said add-on unit comprising an integral main frame assembly on which are mountea an electric motor and a transmission having an output for connection to ground engaging elements of the vehicle, said integral main frame assembly having means for its attachment to the body of the vehicle, such that it lies underneath said vehicle body, and a battery pack carried by a further frame detachably mounted on said integral main frame assembly whereby said vehicle can be converted to electrical drive by fitting said integral frame assembly beneath said vehicle body.
This invention will now be described, by way of example, with reference to the accompanying drawings, in which:-~' :
- ~07~;96Z
Figure 1 is a side elevation view of a motor vehicle converted by means of a unit constructed in accordance with the invention, and ~igure 2 is a plan view of the vehicle.
The vehicle illustrated in outline in the two figures, is a light goods vehicle having a front cab portion indicated generally at 10 and a rear loading area 11~ The vehicle is provided with four wheels, though twin rear wheels may be fitted as required. The front and rear wheels are indicated at 12 and 13 respectively. The vehicle is of the kind originally designed for use with an internal combustion engine drive, which is housed in the front part of the cab at 14.
Drive from the combustion engine would be transmitted through a propeller shaft to the rear wheels through a conventional reduction drive and final drive assembly, which is not, however, illustrated.
The floor of the loading area is indicated at 15, ~
and this may extend to the front of the vehicle, as shown, ~;
when the internal combustion engine has been removed.
The vehicle shown has been converted for electrical drive by removing the engine, reduction gear, propeller shaft and final drive assemblies, and by fitting beneath the floor 15 a composite unit in the form of an integral main frame assembly on which an electric motor 17 and a reduction gear and drive assembly indicated generally at 18 are mounted.
A battery pack 16, carried by a further frame is detachably mounted on said main frame assembly for recharging or replacement of the batteries.
The further frame carrying the battery pack is a large frame occupying a large proportion of the under floor area, as shown in Figure 2. This frame contains a number of individual batteries 19.
'` '~`1' '`
: ~
- , ' : : .
~7~9~
However, it is possible for recharging to take place without the removal of the battery pack.
Provision is made for removing the battery pack from beneath the vehicle.
The main frame assembly has supported on it the motor 17 which, as illustrated in Figure 2, is behind the axis of the rear wheels of the vehicle. The transmission assembly 18 includes a casing containing drive device between a motor 17 and a final drive unit 22 having output shafts connected to the rear wheels of the vehicle. This would usually incorporate a differential mechanism.
Also occupying a space beneath the vehicle floor, and in this case near the front of the vehicle, there is electrical control gear which includes a choke 20 and a chopper 21 for converting the direct current from the batteries into the variable current supplies to the motor 17. Manual control for accelerating and decelerating of the vehicle are furnished within the cab, and replace equlvalent controls fitted in the vehicle for controlling the original internal combustion engine.
The unit described, may be fitted in the vehicle upon original construction or alternatively it may be fitted by conversion from internal combustion engine as described.
The unit may incorporate other components of the electrical drive, and may have the rear wheels of the vehicle assembled to it.
It is possible for the assembly to be so arranged as to drive the front wheels of the vehicle in place of the rear wheels, as shown. The motor may be ahead of the rear wheels if space allows. It is, however, a desirable feature that the entire unit comprising battery pack motor and associated components should occupy a space beneath the floor 17, of the vehicle, without necessitating protrusions therein which would obstruct the load carrying space within the vehicle body.
This invention relates to electrically drive motor vehicles of the kind having a rechargeable battery pack and an electric motor which drives the vehicle through an appropriate reduction transmission.
The invention is principally directed towards vehicles which were originally designed for conventional internal combustion engine drive and particularly though not exclusively to goods vehicles.
