Description
Technical field
The present invention relates to a kind of internal-combustion engine, especially a kind of quartastroke engine of operating according to diesel cycle, it is provided with an engine shaft that has a valve actuator rocker arm, and rocking arm fixedly is fixed on the motor head (engine head) by means of at least one shaft lock device.
The invention still further relates to a motor head and the engine shaft that has rocking arm (rocker) that is used on the internal-combustion engine, it is provided with at least one shaft lock device.
Background technique
The operation of quartastroke engine is based on four different moments, they occur in each stage of its cylinder, that is: the waste gas that detonation of the compression of the suction of pressurized air mixture, this mixture, mixture (the strong motion of consequential piston/bar/crankshaft group) and discharge burning cause.
In order to cause the stroke that these four functions take place, at least one and the synchronous camshaft of bent axle must be arranged, it causes the motion cooperation of the air-breathing and outlet valve and the piston of motor.
Camshaft has a plurality of cams, along with camshaft rotates, and each valve of cam-actuated motor.According to the structure of motor, all cam-actuated only valves are arranged, or actuatable two valves of cam, this situation usually occurs in the V-shaped layout of cylinder, and camshaft is positioned on the engine cylinder-body (engine block).
Yet, with its structure-irrelevant, always there is such motor, its cam directly promotes activated valve by means of it, and, also having such motor, the actuating of its valve realizes by rocking arm, and the cam of rocking arm by camshaft moves.
Therefore, rocking arm is a motor element, and they move by cam, from and movement of valve.Like this, they change to the rotational motion of cam the straight line motion of valve.
In general, rocking arm has roughly an annular, and comprise one with first end of the cam cooperation of camshaft and one and second end of engine valve cooperation.In order to operate rocking arm suitably, it hingedly is connected in the engine shaft that a special design fixes this rocking arm, and this movable joint hinge only has along the moving of rocking arm length direction, and prevents its hinged along other direction, and it may cause valve not activated.
Traditional way is, the engine shaft of support arm is cylindrical basically, and is fixed in motor rigidly, and rocking arm has through hole, so that axle passes through hole.Like this, rocking arm can move fully with respect to axle.
In most of situations, owing to valve is positioned on the motor head, so pitman arm shaft also is positioned on the motor head.Decades ago, because its efficient height also because this is positioned on other parts of motor, so this structure of quartastroke engine is used as engine cylinder-body, although this is possible technically, does not have actual purposes.
In the motor of traditional concept more, camshaft is positioned on the motor body, uses bar to come the actuating engine valve by means of rocking arm.
Yet in the motor of advanced concept more, camshaft is positioned at that head is gone up and near a valve, perhaps, the motor that has has two camshafts that are positioned on the head.Yet, no matter the quantity of camshaft what, some motor of the type has all rocking arms and is used for activated valve, replaces the latter directly by cam-actuated.
Although use decades, pitman arm shaft has some problem, for example is difficulty of head location, and it is undesirable especially in the program of engine maintenance maintenance.
If motor 1 is handled by a machine craftsman who is unfamiliar with the sector fully, then he may be with incorrect mode positioning shaft, or even damages axle and/or head.
It is very important correctly locating pitman arm shaft, as rule, is used for the lubricated inner passage of rocking arm because it has, if it is located improperly, the lubricant oil that then flows on these parts can reduce, or even fuel cut-off, cause it to wear and tear prematurely.
Way traditionally is to realize fixing by screwing on all bearings, can prevent that like this pitman arm shaft from moving, so problem just is to determine before screwing on bearing the correct location of axle.In addition, if they are not correctly screwed on, then the vibration that causes because of the operation of motor can cause the unfavorable motion of axle, and this unfavorable result mentions hereinbefore.
Therefore, in order to be convenient to its correct positioning and to prevent that it from running out of the position when motor to move, above-mentioned solution is ineffective for the locking that solves pitman arm shaft.
Consider above-mentioned shortcoming, existing people proposes a pitman arm shaft that is provided with the radial location pin, and it is located substantially on position intermediate, and towards motor head, motor head has a hole of cooperating with this pin.
Therefore, be enough to like this axle is positioned on the motor head, its way is that pin is incorporated in the hole, thus, guarantees its correct positioning and fixing.This scheme is shown among Fig. 1 of this specification.
Yet, although this scheme can be worked satisfactorily, it can not be used for all engine structures, because in some motor, be used for motor head be fixed to screw on the engine cylinder-body just in time be positioned at a positioned area below, be used for the hole that locating stud uses so can not offer.
For the motor that this mode is constructed, the proposition method of also having no talent is guaranteed the correct location of pitman arm shaft and is prevented the motion that it is accidental reliably, in addition, is convenient to assembling/dismounting motor.

Yet no matter the structure of motor 1 how, it has at least one engine cylinder-body (not shown), and at least one motor head 2 is connected on the engine cylinder-body, and wherein, Aspirating valves and outlet valve (also not illustrating) are positioned on the motor head.Motor head 2 is fixed in engine cylinder-body by means of a plurality of set screw (not shown).
In order to make its operation, motor 1 comprises that at least one is provided with the camshaft (not shown) of cam, and cam rotates with half the angular velocity of camshaft (also not shown) with camshaft in the mode of one.
Camshaft can be positioned on the engine cylinder-body or motor head 2 on, this position and scope of the present invention are irrelevant.The preferred embodiment of motor 1 of the present invention has the single camshaft that is positioned on the motor head 2.
For the ease of opening and closing the valve of motor 1, provide an engine shaft 3 with a plurality of actuator rocker arm 8.Preferably, each valve that is present on the motor head is provided with an actuator rocker arm, but the internal-combustion engine 1 that preferably provides a technology of teaching according to the present invention to constitute, it has one or more rocking arms 8 and activates a valve, or even such motor is provided, the two or more valves on it are activated by single rocking arm 8.
As mentioned above, (comprise motor 1 of the present invention) in most of situations, the engine shaft 3 that comprises rocking arm 8 is positioned on the motor head 2, because be provided with valve in this place just.Because its efficient, this structure of structure quartastroke engine is used decades, and reason is positioned at axle 3 on other parts of motor 1 for this reason, for example on the cylinder body, do not implement in practice, but it is possible with feasible technically.
When motor 1 operation, the rotational angle of bent axle is to ground wedge cam axle, and cam-actuated rocking arm 8.When camshaft was positioned on the motor head 2, the actuating of rocking arm 8 directly was achieved by the contact cam; But when camshaft is positioned on the cylinder body, cam-actuated bar, bar will solve moving of rocking arm 8.
Each rocking arm 8 has ring segment roughly again, even it can also be a rectangle roughly, maybe can have shape other necessity or that require.The preferred embodiment of internal-combustion engine 1 of the present invention also has two dissimilar rocking arms 8, and its shape has many characteristics, and first kind rocking arm designs the Aspirating valves of locomotor, and the second type rocking arm designs the outlet valve of locomotor.
No matter which kind of special shape it is, each rocking arm 8 has one first end 8 ', itself and a cam cooperation of camshaft, and with the first end second opposed end 8 " and engine valve cooperation.
Each rocking arm 8 also has roughly an intermediate portion 80, and it is connected in pitman arm shaft 3, and it rotates around pitman arm shaft.Preferably, this intermediate portion 80 is corresponding to a through hole, and pitman arm shaft 3 is by this through hole location.
Should be noted that: rocking arm 8 can hingedly move along its (rocking arm) longitudinal length direction with respect to pitman arm shaft 3, and in order to prevent the motion of other direction, for example rocking arm 8 is provided with any jack motion-restricting device along the displacement of the direction of pitman arm shaft 3.
Therefore, rocking arm 8 hingedly is connected on the camshaft 3, so that this movable joint hinge only has degrees of freedom along the longitudinal length direction of rocking arm 8, prevent that it is hinged along other direction, because this can cause not activating of valve, cause the disabler of motor 1, and even cause the damage of its inner member.
In order to locate pitman arm shaft 3, motor head 2 should have at least two ends 20 (preferably for relative) that are adapted to this purpose.First-selected is, two ends 20 comprise mach semicircle surface, so that positioning cylinder oblique crank Z 3 correctly, but obviously its shape can be according to its changes of section.
Still be preferably, motor head 2 is provided with the intermediate portion (not shown), and it also has the bearing surface to pitman arm shaft 3.
In a preferred embodiment, motor head 2 comprises that one is referred to as the part of pitman arm shaft framework, and it can separate with the remaining part of motor head.In this case, the end is positioned at the pitman arm shaft framework, but this feature is chosen wantonly.Really, be shown in the part of the motor head 2 in Fig. 3 and 4 corresponding to this framework.
In any case this framework and motor head 2 forms one, thus, its use or do not use includes in the protection domain of attached claims.
For the ease of the assembly and disassembly of motor 1, in regular or interim maintaining process, this point is extremely important, and pitman arm shaft 3 must correctly be located, and then, is fixed in motor head 2.Should be fixing preferably by means of at least one movably standing part 6 implemented, in the preferred versions of a bearing cap, it is one and half ones at least one two and half ones in integrated two ends 20, and is positioned in second half one of corresponding end.Bearing cap 6 pushing shafts 3 make the frictional force maximum between them against motor head 2, and prevent that the former from moving.In the preferred embodiment of the present motor that discloses 1, two bearing caps are arranged, they are positioned in half one of correspondence of end 20 of motor head 3.Yet obviously, dismountable standing part 6 can have other shape that is different from bearing cap.
Although between axle 3 and the motor head 2 frictional force that is enough to stop its motion is arranged, but axle 3 can be positioned on the motor head 2 improperly, so, because the variation of rocking arm 8 in movement process, or even because the minimizing (will explain hereinafter) of lubrication oil circulation on these parts thus, can weaken the function of motor 1.
In order to prevent this point; pitman arm shaft 3 comprises at least one the first pontes 4; it is the form of a radially outstanding pin; and be positioned at an end portion 30 places of pitman arm shaft; motor head 2 comprises at least one second attachment portion 5; it is the preferable form in a hole, and is positioned at an end portion 20 places of motor head.
