Description
SPECIFICATION
Engine and Transmission Arrangement for
Vehicles
The invention relates to an engine and transmission arrangement of vehicles, particularly motor vehicles, having an engine which comprises at least two groups of cylinders which can be coupled to and de-coupled from one another by means of an auxiliary clutch in dependence upon power required from the engine, and having a speed-change gearbox which is connected on the output side and which can be coupled to the engine by means of a further and main clutch.
Prior Patent Application No. P 28 28 298.6 has already proposed an engine arrangement in which, during part load for example, some of the cylinders are rendered ineffective by means of an auxiliary clutch and are rendered effective again only at higher loads. In this construction, the auxiliary clutch was located between the cylinder groups to be coupled and de-coupled, whereas the main clutch associated with the engine and separating the latter from the speed-change gearbox connected on the output side was disposed in a conventional manner at one end of the two cylinder groups, the latter being arranged one behind the other.
The object of the present invention is to provide an engine and transmission arrangement of the kind mentioned initially which is of as compact a construction as possible and which is particularly suitable for small passenger motor vehicles having a front wheel drive.
In accordance with the present invention, the main clutch is disposed between the two groups of cylinders together with the auxiliary clutch and a drive wheel for driving the speed-change gearbox connected on the output side. By virtue of the fact that, in accordance with the invention, the main clutch and the power take-off together with the auxiliary clutch are disposed between the two cylinder groups, an extremely favourable possibility of arranging the gearbox ensues particularly when the main shaft of the units are disposed transversely of the longitudinal direction of the vehicle.Namely, in this case, the differential gear connected on the output side of the speedchange gearbox can be arranged approximately in the longitudinal centre of the space at the front of the vehicle, so that universal joint shafts of equal length are also possible and the entire width of the installation space can be utilized.
Advantageously, the drive wheel can be connected to the main clutch by way of a hollow shaft which is mounted on the crankshaft of the first cylinder group remaining operative or, alternatively, on a member of the housing.
Furthermore, the main clutch and the auxiliary clutch can be disposed axially, directly adjacent one another, the two clutches having a common clutch flywheel which is connected to the crankshaft of the first cylinder group and which embraces the driver discs of the two clutches in a cowl-like manner.
Two embodiments of the invention are illustrated diagrammatically in the drawings and will be further described hereinafter. In the drawings:
Figure 1 is a diagrammatic plan view of the engine and transmission arrangement in accordance with the invention, having a mechanical step-change gearbox,
Figure 2 is a side elevation of the engine and transmission arrangement of Figure 1,
Figure 3 is a plan view of a different engine and transmission according to the present invention in which the speed-change gearbox is constituted by an infinitely regulable or stepless gearbox having an axle drive gear and reversing gear connected on the output side, and
Figure 4 is a side elevation of the engine and transmission arrangement of Figure 3.
In the individual Figures of the drawings, identical or comparable components are provided with the same reference numerals provided in some instances with a prime. A first group and a second group of opposed cylinders 1 a, 1 b and 2a, 2b respectively, that is to say, cylinders disposed opposite to one another, are designated 1 and 2 respectively. The crankshafts of these cylinder groups are designated 1 C and 2c and can be coupled and uncoupled by means of an auxiliary clutch 3.The main clutch connected on the output side of the engine is designated 4 and its output side is connected by way of a hollow shaft 4b to a driven wheel 5 which is in the form of a sprocket wheel and which, together with the hollow shaft 4b, is mounted concentrically on the crankshaft 1 C of the cylinder group 1 which is left permanently coupled to the main clutch. In the present instance, the two clutches 3 and 4 are disposed axially directly adjacent one another and have a common clutch flywheel 19 which is connected to the crankshaft 1 C of the first cylinder group 1 which is also effective during part load, the outer periphery of which clutch flywheel is provided with a wheel rim 1 9a which embraces the driver discs 3a and 4a of the two clutches in a cowl-like manner.
In the present instance, the output of the engine to the change-speed gearbox 8 which is connected on the output side, and which comprises a conventional mechanical stepchange gear in the embodiment of Figures 1 and 2, is effected by means of a chain drive from the driven wheel 5 by way of a chain 7 to a drive wheel 6 which is secured to a drive shaft 9 of the step-change gear 8, or it could be effected by way of an intermediate wheel.A number of gear wheels which are associated with the individual speeds are disposed on this gearbox input shaft 9, some of which gear wheels are in the form of fixed wheels and some of which are in the form of loose wheels, i.e. wheels mounted to rotate on the shaft, the gear wheels meshing with corresponding loose and fixed wheels on the gearbox output shaft 10 and are used to transmit the torque produced by the motor by actuating means which are not further illustrated. An intermediate wheel for realising a reverse gear is designated 11.
A driven wheel 12 is secured to the gearbox output shaft 10 and meshes with the drive wheel 1 3a of a conventional differential gear 13. An axle driving shaft 16 or 1 7 extends out of each side of the differential gear 13, which axle driving shafts are connected to universal joint shafts 14 and 1 5 which lead to the individual driven wheels of the vehicle.
Figure 2 of the drawings shows that the planes of the opposed cylinder groups 1 and 2 slope relative to the longitudinal direction of the vehicle in an engine housing 18, and that the stepchange gearbox 8 is disposed obliquely behind, and partially below, the engine housing 18.
In the embodiment of Figures 3 and 4, the conventional step-change gearbox is replaced by an infinitely regulable or stepless gearbox 20 on the output side of which is connected a planetary gear comprising a single set of planet wheels for the purpose of increasing the axle speed and achieving reverse travel operation. Thus, in this embodiment, the hollow shaft 4b which is connected to the driver disc 4a of the main clutch 4, and which is mounted on a member 35 of the housing 36, is connected to the conical drive ulieys 21, 22 of the stepless gearbox 20.The conical drive pulleys 21,22 are connected to conical output pulleys 24, 25 by way of a chain in the form of a traction element 23, or by way of a
V-belt, the conical drive pulleys 24, 25 in turn being mounted on an axle shaft 16' extending out of the differential gear 13' and being connected to the planetary gear 27 by way of a hollow shaft 26. The drive means for automatic mutual adjustment of the conical drive and output pulleys of the gearbox 20 are not illustrated in the drawings, since they are of conventional construction.
The planetary gear 27 connected on the output side comprises a sun wheel 28, and a number (three, for example) of planet wheels 29 which are distributed around the periphery and which are mounted on a planetary-gear carrier 31 and mesh with the sun wheel 28 and a ring wheel 30 having internal teeth. A sliding sleeve for selectively connecting the planetary-gear carrier 31 or the ring wheel 30 to the drive wheel 1 3a' of the differential gear 13' is designated 32, while a second sliding sleeve 33 selectively connects the ring wheel 30 or the planetary-gear carrier 31 to the housing 34 and thus stops the wheel or the carrier.Thus, when in one position, namely when the sliding sleeve 32 connects the planetary-gear carrier 31 to the drive wheel 13a' and the sliding sleeve 33 connects the ring wheel 30 to the housing 34, forward travelling operation ensues with a transmission step-down predetermined by the construction of the planetary gear, while, when the sliding sleeves 32 and 33 are in their opposite positions, namely, when they connect the ring wheel 30 to the drive wheel 13a' and the planetary-gear carrier 31 to the housing 34, reverse travelling operation ensues with a different transmission step-down.
The diagram of Figure 3 is shown again in
Figure 4 in side elevation, wherein the cylinder plane slopes relative to the longitudinal direction of the vehicles in the same manner as in the embodiment of Figure 2.
In any event, the drawings show that an arrangement proposed by the invention, in which the main clutch and the off-drive to the gearbox are disposed in the centre between the two cylinder groups of the motor, results in a particularly compact engine and transmission arrangement in which, despite utilizing the entire width of the installation space, it is possible to arrange the differential gear in the centre of the vehicle and thus to use universal joint shafts of approximately equal lengths. Since the transmission is in each case located between the, two groups of cylinders, the centre distance can be made very short, this being advantageous with respect to the drive chain in the embodiment of
Figure 1 or the traction element of Figure 3 and with respect to the position of the centre of gravity of the entire unit in the vehicle.The proposed engine and transmission arrangement is thus particularly suitable for small passenger motor vehicles with engines disposed in the front transversely of the longitudinal direction of the vehicles.
The sloping arrangement of the cylinder planes shown in Figures 2 and 4 results in a favourable configuration for a low engine bonnet favourable with respect to air-flow, especially when it is impossible to dispose the cylinders horizontally for reasons of space.
In Figure 1, the hollow shaft 4b which provides the engine off-drive, and which is connected to the driven wheels 5 or 21, 22, is mounted on the crankshaft 1 C which remains effective and, in
Figure 3, it is mounted on a hollow cyiindrical member 35 of the engine housing 36. Although, in principle, it is also possible to mount the hollow shaft 4b on the crankshaft 2e of the cylinder group 2 which can be rendered effective, the crankshaft 2e is not subjected to transverse force in the illustrated arrangements, this being advantageous with respect to the starting of the crankshaft 2e which would otherwise be impaired by mixed friction in the crankshaft bearings.
It may also be mentioned that the transmission arrangements illustrated in the drawings are only exemplary embodiments and, it will be appreciated, do not constitute limitations with respect to possible embodiments of transmissions. Thus, it will be appreciated that multi-step planetary gears can be provided instead of a mechanical step-change gear and, in the embodiment of Figure 3, a spur wheel gearbox having an intermediate shaft for realising the reverse gear can be provided instead of the planetary gear 27.
Other embodiments of engines can also be provided, such as in-line engines, which can also be split up into groups having different numbers of cylinders.
