Abstract

An auxiliary drive assembly (6), in the form of either a trailer, as shown, or alternatively a tractor unit, when coupled through plates (7) and clevis pins (8) to clevis connections (5) on a conventional vehicle (2) converts it into a composite hybrid vehicle (1) capable of being at the choice of the user propelled by either the original integral engine (3) of the basic conventional vehicle (2) or the auxiliary drive assembly. The auxiliary drive unit (6) contains an energy store, motor and power transmission means and is provided with a single road-engaging wheel arranged on a mounting pillar which allows the wheel to 'castor' as the vehicle assembly (1) turns corners. Operation of the auxiliary propulsion assembly is controlled from the driver's seat by means of auxiliary driving controls connected to the auxiliary propulsion assembly by means of a plug-in control cable (11). The plates (7), clevis pins (8) and clevis connections (5) permit articulation of the auxiliary propulsion assembly about a horizontal transverse axis whilst preventing articulation about a vertical axis. A battery-powered auxiliary drive may be employed for a basic motor vehicle designed primarily for long- distance high-speed operation: when, for instance it is to be used for a period in low speed urban traffic or for door to door delivery work or motor fuel is in short supply. A battery-powered vehicle designed for slow-speed operation may have an auxiliary internal combustion engine powered unit capable of propelling it at a good road speed to the district in which its delivery round is to be run under battery power. <IMAGE>

Description

SPECIFICATION Vehicle propulsion This invention relates to vehicle propulsion, and more particularly to a vehicle having a main propulsion mechanism and an auxiliary propulsion mechanism which can be used to propel the vehicle instead of the main propulsion mechanism.
There are well recognised advantages to the use of electric propulsion for vehicles used within towns and cities. Electric propulsion is quiet, energy efficient, and substantially polution free. However, electric storage batteries presently available for use in propelling vehicles are heavy and do not provide sufficient storage capacity for long-range or highspeed propulsion of a vehicle.
It has been proposed to build a hybrid vehicle which includes an internal combustion engine for providing power for high-speed and long distance motoring, and a battery powered electric motor for use instead of the internal combustion engine for town and city driving. Known systems suffer, however, from the disadvantage that the batteries and motor are an integral part of the vehicle and must accordingly be carried with the vehicle at all times. As mentioned previously the batteries are extremely heavy, and on a long distance high-speed journey are a considerable inconvenience. Indeed, if batteries of presently available design are used they add so much to the weight of the vehicle that the reduction in performance and increase in fuel consumption of the vehicle when powered by its internal combustion engine are largely unacceptable.
According to one feature of the present invention there is provided a vehicle assembly comprising: a passenger vehicle incorporating a main propulsion assembly capable of propelling the vehicle; and an auxiliary propulsion assembly releasably attached to the passenger vehicle and capable of propelling the vehicle assembly, when the main propulsion assembly is not in use.
The passenger vehicle is preferably a conventional mass-produced internal combustion engined motor car modified by the provision of coupling means at its rear end for coupling with the auxiliary propulsion assembly. Coupling means may be provided in a simple manner on a tow bar assembly secured to the vehicle. The auxiliary propulsion assembly is in the form of a trailer having coupling means complementary to the vehicle coupling means so that the trailer can be secured behind the vehicle and is rotatable relative to the vehicle about a horizontal axis parallel to the axis of the rear wheels of the passenger vehicle. The provision of a rotatable connection between the passenger vehicle and the auxiliary propulsion assembly ensures that the auxiliary propulsion assembly can move relative to the passenger vehicle to accommodate variations in road surface.Preferably, however, the auxiliary propulsion assembly is not rotatable relative to the vehicle about a vertical axis. In the preferred embodiment two horizontally spaced apart rotatable connections connect the passenger vehicle to the auxiliary propulsion assembly.
The auxiliary propulsion assembly of the preferred embodiment comprises a trailer provided with a single ground-engaging drive wheel which can be rotated to propel the entire vehicle assembly by means of an electric motor driven by batteries housed within the trailer body. Thus, when the auxiliary propulsion assembly is secured to the passenger vehicle the assembly can be driven either by the internal combustion engine of the passenger vehicle or by the battery powered motor of the auxiliary propulsion assembly. Typically, the auxiliary propulsion assembly will be used to drive the vehicle assembly at low speeds within towns, and at this time the passenger vehicle engine will be switched off.On the open road where greater speed and range than that which can be provided by the batteries is required, the internal combustion engine of the passenger vehicle will be used to drive the vehicle assembly.
On any particular occasion when the auxiliary propulsion assembly is not required, for example if a long distance high-speed journey is contemplated, the auxiliary propulsion assembly is simply disconnected from the passenger vehicle and is not used.
The passenger vehicle then functions as an entirely normal production car. At such times, the auxiliary propulsion assembly is preferably left on charge at the home of the owner. When the auxiliary propulsion assembly is next required for use, e.g. on a commuting journey into a city on the following day, it is re-connected to the passenger vehicle and the assembly used as described above.
Accordingly, the preferred embodiment of vehicle assembly according to the present invention has all the advantages of a hybrid vehicle which can be propelled at the choice of the user either by an internal combustion engine or by an electric motor, whilst at the same time the inherent disadvantages of a vehicle which is permanently compelled to carry heavy batteries are avoided.
The above and further features and advantages of the present invention will become clear from the following description of a preferred embodiment thereof, given by way of example only, reference being had to the accompanying drawing wherein: Figure 1 is a schematic side elevation of a vehicle assembly according to the present invention; and Figure 2 is a pian view of the assembly of Figure 1.
In the drawing, there is schematically shown a vehicle assembly 1 comprising a conventional passenger motor car 2 provided with a front mounted internal combustion engine 3 which drives the front wheels 4 of the vehicle through a conventional gear-box. The vehicle 2 is modified by the provision of a tow-bar at its rear and on which are mounted two pairs of clevis connections 5. An auxiliary propulsion assembly 6 is coupled to the vehicle by means of plates 7 and clevis pins 8 so that it can be drawn behind the passenger car 2 in a trailer-like manner, or can apply a propulsive force to the car 2.
The clevis pins 8 are axially aligned and permit articulation of the auxiliary propulsion assembly relative to the motor car about a horizontal axis parallel to the axis of the driving wheels 4. This articulation ensures that the auxiliary propulsion assembly can move vertically relative to the motor car to accommodate variations in the road surface oven which the vehicle assembly is passing.
The auxiliary propulsion assembly 6 comprises a body 7 within which is housed a plurality of electric storage batteries, for example lead-acid accumulators. The storage batteries provide electric power to drive an electric motor forming part of the auxiliary propulsion assembly. The electric motor in turn drives a single road-engaging wheel 8 of the auxiliary propulsion assembly. Although a single roadengaging wheel 8 is used in the preferred embodiment it will be appreciated that more road-engaging wheels all or some of which may be driven can be used if desired.
The manner of mounting the wheel 8 on the body 7 is not critical, but preferably is arranged on a mounting pillar which will "castor" i.e. will automatically align the wheel in an appropriate direction as the vehicle assembly turns corners. If castored mounting of the wheel 8 is provided the arrangement is preferably adjustable in order to provide for a non-castoring orientation of the wheel when the entire assembly is being driven by the internal combustion engine 3 and possibly for a reverse castoring of the wheel if it was desired to reverse the vehicle assembly by means of the auxiliary propulsion assembly.
Appropriate reduction gearing may be provided between the electric motor and the wheel 8, and appropriate control circuitry will be provided for the electric motor.
Operation of the auxiliary propulsion assembly is controlled from the driver's seat by means of auxiliary driving controls mounted in a convenient position, for example on the dash-board of the vehicle. The auxiliary driving controls are connected to the auxiliary propulsion assembly by means of an electric cable. Preferably, the portion of electric cable from the auxiliary controls to the rear of the vehicle 2 is permanently routed through the vehicle and a socket is provided at the rear end of of the cable to facilitate plug-in connection of a control cable 9 of the auxiliary propulsion assembly.
The composite vehicle assembly as illustrated in the drawing is intended for town driving, or mixed town and country driving. Typically, the user of the vehicle assembly will start from home in the morning using the internal combustion engine 3 to drive the entire assembly with the auxiliary propulsion assembly 6 being towed in the manner of a trailer.
This will continue until the driver reaches the outskirts of a town and encounters traffic congestion. At this time he will switch off the internal combustion engine 3 and drive the composite vehicle using the auxiliary propulsion assembly 6 which he will control via the dash-board mounted auxiliary controls. When he returns home in the evening he will again use the auxiliary propulsion assembly until he reaches the outskirts of the town and will then switch to the internal combustion engine 3 for his journey home. If on a particular occasion he does not expect to need the auxiliary propulsion assembly, if for example he is going on a long motorway drive or is going on holiday, he can simply remove the clevis pins 8 and unplug the cable 9, and leave the auxiliary propulsion assembly at his house.The car 2 then acts as a conventional internal combustion engine car and is not burdened with the considerable weight of the lead-acid accumulators contained within the housing 7. On such occassions the auxiliary propulsion assembly can conveniently be left in the garage of the owner with the batteries on charge. In normal daily use the batteries will be charged each night, or during the working day when the vehicle assembly is not required.
It will be appreciated that the above described assembly provides the advantages of both an electrically powered vehicle and an internal combustion engine powered vehicle. When the assembly is complete as illustrated in the drawing it may be driven optionally from either the batteries or the internal combustion engine, and if the batteries are not required on some particular occasion the entire auxiliary propulsion assembly can be quickly and conveniently removed.
Since the auxiliary propulsion assembly is very simple in construction it can be manufactured very robustly at an economic price. Further, since the modification of the standard production vehicle required in orderto use the auxiliary propulsion assembly consists merely of providing a tow-bar with clevis mountings, together with the routing of the control cable, it will be appreciated that a single auxiliary propulsion assembly may be purchased and can be used with several successive cars owned by the owner of the auxiliary propuision assembly.
It will be appreciated that many modifications may be made to the above described design within the scope of the present invention. For example, whilst the preferred location of the auxiliary propulsion assembly 6 is to the rear of the vehicle, there may be some applications in which the unit is more conveniently placed in front of the vehicle.
Although in the preferred embodiment of the invention the auxiliary propulsion assembly is powered by electric storage batteries, any convenient source of power may be used. For example, the auxiliary propulsion assembly may include a Liquid Petroleum Gas (LPG) tank and a small LPG powered engine connected to the driving wheel of the auxiliary propulsion assembly by a suitable transmission.
