Description
ADJUSTABLE EXHAUST SYSTEM
This invention relates to exhaust systems for motor vehicles and, in particular, to exhaust systems in which the position of the exhaust system relative to an internal combustion engine to which it is connected can be readily adjusted during the connection procedure.
Exhaust systems for motor vehicles are known in all shapes and sizes, but the majority of such systems normally include an exhaust inlet pipe shaped to connect to an exhaust duct on an internal combustion engine of the motor vehicle, an exhaust silencer connected to the exhaust inlet pipe, and an exhaust outlet pipe connected to the silencer. In many such systems, the silencer and the exhaust outlet pipe are mounted on the chassis or bodywork of the motor vehicle, and, because the engine of the vehicle, when operating, vibrates at a different frequency to the chassis or bodywork of the vehicle, it is necessary to employ some form of reslient mounting between the silencer, the exhaust outlet pipe and the chassis or bodywork to prevent premature structural failure of the exhaust system due to vibration.
In some designs of motor vehicles, such as agricultural tractors, commercial tractors and large commercial vehicles, this problem of differing vibration rates between the engine and the chassis of the motor vehicle can be overcome by mounting the exhaust system directly upon the engine, without there being any mechanical connection between the exhaust system and the chassis of the vehicle. The present invention relates specifically to an engine-mounted system of that type.
An exhaust system according to the present invention, for a motor vehicle engine having an exhaust duct, comprises a silencer having a longitudinal axis, an exhaust inlet pipe to the silencer and an exhaust outlet pipe from the silencer, the connection of one end of the exhaust inlet pipe to the silencer being adjacent one end of the silencer and substantially at right angles to the connection of the exhaust outlet pipe to the silencer, and adjustable mounting means positioned at the other end of said silencer for mounting said silencer upon said motor vehicle engine, the other end of said exhaust inlet pipe being provided with a flanged collar thereon which is releasably engageable with a co-operating formation on one end of said exhaust duct to form a sleeved connection therewith which, when clamped by means of an encircling clamping ring, provides a gas-tight joint between the exhaust duct and the exhaust inlet pipe, and which, when unclamped, allows rotational movement of said exhaust inlet pipe with respect to said exhaust duct about a longitudinal axis of said sleeved connection, an adjustable mounting means being provided on said exhaust inlet pipe adjacent said flanged collar and engaging with co-operating formations on said motor vehicle engine to provide sufficient spacial adjustment of said flanged collar with respect to said co-operating formation on said exhaust duct as to allow the formation of said sleeved connection, and the adjustable mounting means on the other end of the silencer comprising a releasable clamping device mounted on said motor vehicle engine which, when released, allows both rotational movement and longitudinal movement of said silencer relative to said motor vehicle engine to occur about said longitudinal axis of said silencer.
Preferably, both the exhaust inlet pipe and the exhaust outlet pipe are connected to the silencer at right angles to the longitudinal axis of the silencer.
Thus this invention provides an engine-mountable, compact exhaust system which is provided with readily adjustable mounting means to allow the easy and rapid connection or disconnection of the exhaust system with the engine without any problems due to any misalignment that might exist between the components of the exhaust system and the engine. Such an easy and rapid connection and disconnection provides a marked improvement in the rate and quality of fitting such exhaust systems on the production line during the manufacture of motor vehicles fitted with exhaust systems according to the present invention, and in the servicing of such vehicles during their operating lives.Moreover, by adopting the particular spatial arrangement between the exhaust inlet pipe, the silencer and the exhaust outlet pipe in the present invention, it is possible to obtain a compact exhaust system whilst retaining a silencer of satisfactory size and performance to deal with the exhaust gases emitted by the engine on which the exhaust system is mounted.
Preferably, when the exhaust system according to the present invention is mounted upon a motor vehicle engine, the longitudinal axis of the silencer is substantially parallel to the longitudinal axis of the motor vehicle engine, and the exhaust system resides within the confines of the cab/engine envelope of the motor vehicle in which the motor vehicle engine is mounted.
An exhaust system according to a preferred embodiment of the present invention is one in which the adjustable mounting means provided on said exhaust inlet pipe comprises a slotted plate secured to said exhaust inlet pipe which has slotted apertures therein extending in one direction, and a right-angled support bracket in the form of a cranked plate, each flat section of which has slotted apertures formed therein, one of said flat sections being coupled to said slotted plate by screwed fasteners passing through superimposed slotted apertures in the plate and in said one flat section, the slotted apertures in said one flat section extending in a direction at right angles to said one direction, the slotted apertures in said other flat section extending in a direction that is mutually at right angles to the slotted apertures in both the plate and in said one flat section, and the co-operating formation on said motor vehicle engine comprises an apertured flange on said engine, screwed fasteners being passed through respective slotted apertures in said other flat section and respective apertures in said flange in order to mount said exhaust inlet pipe in position on said engine and to form said sleeved connection with the exhaust duct.
Preferably in this preferred embodiment of the invention, the silencer is cylindrical in shape, and the releasable clamping device is a flexible strap-like member in the form of a circular loop which passes around the silencer adjacent said other end thereof, the free ends of the member each extending substantially radially outwards from the loop and being attached to an apertured flange on said engine by screwed fasteners, each of which is threaded through respective aligned apertures in said free ends and in said flange, the silencer being held by frictional engagement between said strap-like member and an outer surface of said silencer when said screwed fasteners are tightened-up.

Figure 8 shows a partial, cross-sectional view of the connection between the exhaust inlet pipe shown in Figure 3 and the exhaust duct shown in Figures 5 and 6, using the clamping ring shown in Figure 7.
A preferred embodiment of the present invention is shown in Figure 1, and comprises an exhaust system 10 for a military vehicle powered by a diesel engine fitted with a turbocharger (not shown), the exhaust duct 12 of which appears in Figures 1, 5 and 6 of the accompanying drawings. The exhaust system 10 comprises a cylindrical silencer 14 having a longitudinal axis 16, an exhaust inlet pipe 18 to the silencer 14, and an exhaust outlet pipe 20 from the silencer 14, both the exhaust inlet pipe 18 and the exhaust outlet pipe 20 being connected to the silencer 14 at right angles to said longitudinal axis 16, with the connection of one end of the exhaust inlet pipe 18 to the silencer being adjacent one end of the silencer and substantially at right angles to the connection of the exhaust outlet pipe 20 to the silencer.The exhaust outlet pipe 20 is connected to the silencer 14 by being inserted in a slotted sleeve 19 extending at right angles to the longitudinal axis 16 of the silencer, and is retained therein by the adjustable clamp 21.
An adjustable mounting means 22 is provided on the other end of the silencer 14 for mounting the silencer upon the engine (not shown), and comprises a releasable clamping device in the form of a flexible strap-like member 34 which loops around the silencer adjacent said other end thereof, the free ends 36,38 of the strap-like member each extending substantially radially outwards from the silencer and being attached to an apertured flange 40 on said engine by screwed fasteners, each of which comprises a threaded bolt 42, washer 44, washer 46 and threaded nut 48.The apertured flange 40 is a cranked plate having two sides at right angles to one another, with two circular apertures 50 formed in one of said sides through which are threaded mounting bolts 52, each mounting bolt 52 being screwed into a corresponding threaded aperture (not shown) in a frame portion 54 of the engine to secure the apertured flange to the engine. Spring washers 56 are interposed between the bolt heads of the mounting bolts 52 and the one side of the apertured flange 40 to provide shake-proof connections. The other side of the apertured flange 40 has two slotted apertures 58 formed therein, one above the other, and arranged to extend substantially horizontal when the apertured flange is mounted upon the frame portion 54.
The free end 36 of the strap-like member 34 has a circular aperture 60 formed therein, and is secured to the apertured flange 40 by one of the bolts 42 passing through the upper slotted aperture 58 and the circular aperture 60, and one of the nuts 48 being threaded onto said bolt and being tightened thereon.
The free end 38 of the strap-like member 34 has a cranked configuration and a circular aperture 62 formed therein. Free end 38 is secured against the free end 36 by the other bolt 42 passing through the lower slotted aperture 58 in the apertured flange, a circular aperture (not shown) in free end 36, a bushing 64 interposed between the free end 36 and the free end 38, and the circular aperture 62 in free end 38, with the other nut 48 being threaded onto said bolt and being tightened thereon. When the nuts 48 are fully tightened upon the bolts 42, the silencer 14 is secured firmly to the engine by the frictional engagement of the strap-like member 34 with the outer cylindrical surface of the silencer.
The other end of the exhaust inlet pipe 18 is provided with a flanged collar 24 thereon, which is releasably engageable with a co-operating formation, in the form of a flanged sleeve 26, provided on one end of the exhaust duct 12. The flanged collar 24 is shown in more detail in Figure 3 of the drawings, from which it can be seen that the flanged collar has a tubular portion 66 which fits snugly around said other end of the exhaust inlet pipe 18 and is secured thereto by an annular weld 68. The remaining portion 70 of the flanged collar is in the form of a bell-mouth which terminates in an inclined annular rim 72.The flanged sleeve 26 on the exhaust duct 12 from the turbocharger is shown in Figures 5 and 6 of the drawings, and comprises a lower tubular portion 74 having an outer diameter such that this lower tubular portion 74 is a loose, sliding fit within the tubular other end of the exhaust inlet pipe 18, and an upper annular tapered shoulder 76 having an upper inclined face 78, a peripheral end face 80, and a lower inclined face 82 which is inclined at the same angle of inclination as is the inclined annular rim 72 of the flanged collar 24. The flanged sleeve 26 surrounds said one end of the exhaust duct 12, and is secured thereto by an annular weld 84 (see Figure 8).
The connection of the exhaust inlet pipe 18 to the exhaust duct 12 is achieved by inserting the lower tubular portion 74 of the flanged sleeve 26 into the bell-mouth portion 70 of the flanged collar 24 until the lower tubular portion 74 enters said other end of the exhaust inlet pipe 18 and the lower inclined face 82 of the tapered shoulder 76 comes into contact with the inclined annular rim 72 of the flanged collar, thus forming a sleeved connection between the exhaust inlet pipe 18 and the exhaust duct 12 which, when unclamped, will allow rotational movement of the exhaust inlet pipe with respect to the exhaust duct about a longitudinal axis 30 of the sleeved connection.
Clamping of the sleeved connection by means of an encircling clamping ring 28 provides a gas-tight joint between the exhaust duct 12 and the exhaust inlet pipe 18 by reason of the contact between the complementary inclined surfaces of the annular rim 72 and the lower face 82.
Details of the clamping ring 28 are shown in
Figures 7 and 8 of the drawings, from which it can be seen that the clamping ring is made up of an annular inner channel-shaped member 86 formed from three arcuate segments, each one of which is welded at the base of the channel to an outer annular member 88 formed from a flat strip of resilient metal. As can be seen from the cross-sectional view shown in Figure 8, the inner channel-shaped member 86 has channel sides 90 inclined at the same angles as the angles of inclination of upper face 78 and lower face 82, and the edges of the channel sides 90 terminate in flange portions 92 which lie parallel to the outer annular member 88. One end 94 of outer annular member 88 (see
Figure 7) is reversely-bent around a head 96 of a
T-bolt 98 and is then secured to the outer annular member by spot-welding at 100.The other end 102 of outer annular member 88 is reversely-bent around a cylindrical member 104 and is then secured to the outer annular member by spot-welding at 106. A threaded shank 108 of T-bolt 98 passes through appropriate apertures (not shown) in the reversely-bent sections of the outer annular member 88 and in the cylindrical member 104, and a self-locking nut arrangement 110 is threadingly-engaged with the threaded shank 108. Threaded movement of the nut arrangement 108 towards the head 96 of T-bolt 98 causes the diameter of the clamping ring 28 to decrease, and vice-versa, in a manner well known in the art.
As can be seen in Figure 8, the clamping ring 28 encircles the juxtaposed annular rim 72 and the annular tapered shoulder 76 so as to house both the annular rim and a substantial portion of the tapered shoulder within the confines of the annular inner channel-shaped member 86, with a flange portion 92 of the channel-shaped member in contact with the bell-mouth portion 70 of flanged collar 24.
Consequently, the tightening of the clamping ring 28 around the annular rim 72 and the tapered shoulder 76 by the threaded movement of the nut arrangement 108 towards the head 96 of the T bolt 98 results in a substantial annular area of contact between the complementary inclined surfaces of the annular rim 72 and the lower face 82 to provide an effective metal-to-metal gas-tight joint between the exhaust duct 12 and the exhaust inlet pipe 18 without the need for any sealing gasket therebetween.
A slotted plate 108 is welded to the exhaust inlet pipe 18 close to the flanged collar 24, as shown in Figures 2 and 4. The plate 108 has a portion thereof lying in a plane which is parallel to the longitudinal axis 30 of the flanged collar 24, which portion has two oval-shaped slots 110 and 112 formed therein, one above the other, as shown in Figure 2, which extend in a direction at right angles to the longitudinal axis 30 of the flanged collar 24. A right-angled support bracket 114 in the form of a cranked plate (see Figure 1) has flat sections 116, 118, each of has two slotted apertures formed therein, one above the other.Flat section 116 has slotted apertures 120, 122 formed therein, each of which extends parallel to the right-angled bend in the support bracket 114, and flat section 118 has slotted apertures 124, 126 formed therein, each of which extends at right angles to the right-angled bend in the support bracket 114. Support bracket 114 is connected to slotted plate 108 by means of a pair of bolt assemblies 128,130,132,134, only one of which is illustrated in Figure 1. Each bolt assembly comprises a threaded bolt 128, a washer 130, a shake-proof washer 132 and a threaded nut 134, and one of the bolt assemblies 128,130,132,134 passes through slot 110 and aperture 120, and the other bolt assembly 128,130, 132,134 passes through slot 112 and aperture 122.
Since the axes of the slots 110 and 112 extend at right angles to the axes of the slotted apertures 120 and 122, it will be appreciated that it is possible to spacially adjust the position of the flat section 116 of the support bracket 114 relative to the slotted plate 108.
A support flange 136 is provided upon the engine which has two apertures 138,140 formed therein, one above the other in a vertical plane. The support bracket 114 is connected to support flange 136 by means of a pair of bolt assemblies 142,144,146,148, only one of which is illustrated in Figure 1. Each bolt assembly comprises a threaded bolt 142, a washer 144, a shake-proof washer 146 and a threaded nut 148, and one of the bolt assemblies 142,144,146,148 passes through slotted aperture 124 and aperture 138, and the other bolt assembly 142,144,146,148 passes through slotted aperture 126 and aperture 140.Since the axes of slotted apertures 124 and 126 extend horizontally when the flat section 118 of support bracket 114 is connected to support flange 136, it will be appreciated that it is possible to spacially adjust the horizontal position of the flat section 118 of the support bracket 114 relative to the support flange 136 before tightening the bolt assemblies 142,144,146,148.
Consequently, the effective three-dimensional adjustment of the position of the exhaust inlet pipe 18 relative to the support flange 136 provided by the spacial adjustment of the support bracket 114 relative to both the inlet pipe 18 and the support flange 136, allied with the rotational adjustment possible between the flanged collar 24 and the flanged sleeve 26 is amply sufficient to compensate for any eccentricity or misalignment between the exhaust duct 12 and the exhaust inlet pipe 18, or any stack-up of tolerances in the components of the exhaust system of the present invention. Thus the present invention provides a simple, effective and inexpensive exhaust system which can be rapidly installed on an engine by gas-tight connections, without stress problems caused by misalignment between components.
