摘要:
A frame for supporting implements (18,20) on a vehicle with a chassis including a transversely extending axle housing (110). The frame includes a pair of longitudinally extending rails (58), each rail having first and second end portions and a tower structure (54) extending upwardly from a location intermediate the end portions. First interconnecting means (56) interconnect and maintain the first end portions of the rails in a fixed transversely spaced apart relation, the second end portions being arranged to be secured to second interconnecting means such as a counterweight (118) or backhoe structure (40) to maintain said second end portions in a fixed transversely spaced relation. Means (92, 96) are provided for connecting the first end portions to the vehicle chassis and a stabilizing means (128) extends between the tower structures which permits constrained movement of the tower structures so that the rails can deflect under torsional loading. Attachment means (98) are also provided for attaching each rail to the axle housing (110) intermediate the ends of the rail.

In an internal combustion engine comprising a piston (1) having a combustion bowl (3) recessed in the crown of the piston and a plurality of arcuate recesses (7) formed in the side wall (6) of the bowl spaced apart by arcuate intermediate portions of the side wall, swirl means to cause the inlet air to rotate about the axis of the bowl, and fuel injection means (2) that serves to direct a plurality of fuel jets radially of the bowl each towards a corresponding recess (7), the piston is characterised in that the ratio of the maximum distance by which each recess (7) extends radially into the side wall (6) compared with the radius of the side wall (6), lies within the range 0.10 to 0.20.
摘要:
A vehicle drive arrangement in which a drive shaft (10a) is coupled with a first hollow driven shaft (12) and a second driven shaft (11) within hollow driven shaft (12) by first (14) and second (13) coaxial clutches respectively. Clutch (13) which is adjacent flywheel (10) is operated by a force transmitting path in the form of pins (17) located outside both driven shafts and passing axially through the central portion (24) of clutch (14). This produces a more compact arrangement since the force transmitting path for the operation of clutch (13) does not pass around the outer periphery of clutch (14).
摘要:
Capot de machine comprenant un corps principal (1) possédant deux ouvertures ou davantage (6) fermées par des fermetures interchangeables (8, 9), dont l'une au moins incorpore une conduite d'admission (12) de manière à pouvoir placer cette conduite d'admission en une, deux positions ou plus dans le capot. Une paire de fermetures interchangeables pour une paire d'ouvertures adjacentes peut être formée dans un composant unique (8) qui est réversible bout à bout et qui agit de concert avec les deux ouvertures (6) de sorte que la conduite de remplissage (11) est alignée avec une des ouvertures tandis que l'autre est fermée. Une ou plusieurs fermetures permettent de fermer chacune des autres ouvertures, une fermeture (9) étant prévue pour chaque paire d'ouvertures adjacentes, si nécessaire. Dans une variante, la fermeture (8) incorporant la conduite de remplissage (11) peut s'engager dans chaque ouverture (16) selon une ou plusieurs orientations différentes, dans chacune desquelles la conduite de remplissage est située dans une position différente.
摘要:
A mower conditioner having a conditioning rotor (22) which is supported at its ends in bearing units (51) that are secured to side support walls (24) by releasable fastening means (56) including a pair of coaxial fasteners defining an axis (68), parallel to that of the rotor axis (23), about which the bearing units (51) and rotor (22) can swing downwards until the rotor (22) contacts the ground, thereby facilitating removal and re-attachement of the conditioning rotor (22). The rotor axis and axis of the fasteners may lie in a plane that is inclined upwards and rearwards from the ground. The rotor (22) may be driven atone end by a spindle (81) that is axially disengageable from the rotor. The spindle (81) may be driven by a chain drive mechanism (71, 76) including an intermediate double ring sprocket (73) that is reversible on its shaft (86) to allow two drive ratios to be selected.
摘要:
A piston for an internal combustion engine comprising a piston body (1) and a crown portion (3) that are connected by anchoring means comprising elongate members (7, 23, 26, 79, 80) that extend from the crown portion (3) into the piston body (1) so as to transmit tensile and compressive loads from the crown to a portion of the piston body in a region spaced axially away from the crown portion at a temperature which, at maximum operating temperatures, is low enough to prevent loosening of the anchoring means, characterized in that cooperating surfaces of said anchoring means (7, 9, 16) and piston body (1) are pre-loaded into contact with one another by virtue of strain energy stored in the anchoring means and piston body (1) and which acts axially to prevent parting of said cooperating surfaces by said tensile and compressive loads without being dependent on any reaction forces between the adjacent faces of the crown portion and piston body. Said anchoring means may comprise at least one member (7) that is inserted into a bore (12) in the piston body and is rigidly connected axially to the crown portion (3) at one end and rigidly axially connected to said portion of the piston body at its other end. Alternatively, said anchoring means may comprise at least one strut member (79) that extends from the crown portion (3) into a bore (82) in the piston body (1) so as to absorb compressive forces therebetween and thereby relieve compressive loading of the adjacent faces of the piston body (1) and crown portion (3), and at least one tie member (80) that is connected between the piston body (1) and crown portion (3) to restrain separation and that is pre-loaded in tension.
