Embodiment
It should be noted that in the case where not conflicting, the spy in embodiment and embodiment in the utility model
Levying to be mutually combined.
Below with reference to the accompanying drawings and combine embodiment and describe the utility model in detail.
The utility model provides a kind of Engine Block Test structure, and the Engine Block Test structure includes engine 1, installed
In the double-clutch speed changer flywheel of the engine 1, the double-clutch speed changer flywheel includes preliminary quality 2 and secondary mass 3, its
In, the Engine Block Test structure includes being removably installed in the support 4 of the engine 1, and the support 4 is provided with support
Axle 5, one end of the support shaft 5 is fittingly inserted into institute from a side clearance of the secondary mass 3 away from the preliminary quality 2
In the central shaft hole for stating secondary mass 3, the secondary mass 3 can rotate relative to the support shaft 5.
The preliminary quality 2 of the double-clutch speed changer flywheel is installed on the crankshaft flange of engine 1, and secondary mass 3
For installation into speed changer, in test engine, due to secondary mass 3 is not installed on into speed changer, therefore on engine 1
Mounting bracket 4, secondary mass is supported by the support shaft 5 on support 4.Wherein, as speed changer alternative structure support shaft 5
The installation site of speed changer is located substantially at, certainly, support shaft 5 keeps gap to coordinate with secondary mass 3, it is to avoid support shaft 5 is produced
The resistance for hindering secondary mass 3 to rotate, in this structure, support shaft 5 can support secondary mass 3 well, it is to avoid secondary matter
Amount 3 with preliminary quality 2 rotate when produce and radially wobble, protect the attachment structure between secondary mass 3 and preliminary quality 2,
Such as support ring and centrifugation pendulum-type bump leveller, especially, compared to frock flywheel, the processing and manufacturing and installation of support 4 are relative
It is relatively simple, production cost can be reduced, operating efficiency is improved.
Specifically, the central shaft hole is splined hole, and the support shaft 5 and the minimum diameter gap of the splined hole are matched somebody with somebody
Close.The core of secondary mass 3 is splined hub, and is formed with splined hole, and speed changer is connected in order to install.The spline
Spline is formed with the inwall in hole, that is to say, that the internal diameter of splined hole is not that unification is constant, still, support shaft 5 and institute
The minimum part holding gap cooperation of the internal diameter of splined hole is stated, both secondary mass 3 can be allowed to rotate freely through, and can limited again
Secondary mass 3 produces radial displacement.
In addition, the support shaft 5 is formed with the outer peripheral face of the part of the secondary mass 3 for the secondary matter of backstop
The defining flange 51 of amount 3.As shown in Fig. 2 defining flange 51 is adjacent to secondary mass 3, the external diameter of defining flange 51 be more than it is described in
The internal diameter of arbor hole or the splined hole, due to secondary mass 3 be not fixedly connected with support shaft 5, secondary mass 3 there is also
A certain amount of axial wobble, can limit secondary mass 3 by defining flange 51 and be axially distant from preliminary quality 2, protection is secondary
Attachment structure between quality 3 and preliminary quality 2.
Further, the defining flange 51 and the secondary mass 3 that remains static at intervals of 3-5mm.Limit
Position flange 51 can try one's best keeps interval without contacting with secondary mass 3, reduces the influence to the secondary mass 3 of rotation, that is, locates
In the secondary mass 3 (engine is not actuated, and double-clutch speed changer flywheel is in not rotation status) and defining flange of inactive state
A small amount of interval is reserved between 51, is only just started when secondary mass 3 produces axial displacement relative to original position of inactive state
Contacted with defining flange 51, defining flange 51 can limit secondary mass 3 and further be axially offset from original position, it is seen then that
The distance that is axially displaced from of secondary mass 51 is maintained at less scope by defining flange 51.
Preferably, the support shaft 5 is rotatably mounted in the support 4 by bearing 6.Bearing 6 can be conventional
Bearing part, including the structure such as outer ring and inner ring, the outer ring of bearing 6 can be fixed on support 4, and support shaft 5 can be fixedly connected
In inner ring, so that support shaft 5 can rotate relative to support 4.In this structure, support shaft 5 can be synchronous with secondary mass 3
Or asynchronously rotate, reduce resistance of the support shaft 5 to secondary mass 3.
Specifically, the support 4 includes the support arm 41 across the secondary mass 3, and the support arm 41, which is formed with, to be passed through
Logical mounting hole, the bearing 6 is fixed in the mounting hole, and the two ends of the mounting hole are separately installed with described in backstop
The bearing cap 7 of bearing 6, two bearing caps 7 are respectively formed with through hole to allow the support shaft 5 to pass through.Such as Fig. 1 and Fig. 2
Shown, support arm 41 is across secondary mass 3 and is spaced, and the mounting hole can be coaxial with the central shaft hole of secondary mass 3
Line, it is ensured that support shaft 5 is coaxial with secondary mass 3.Bearing 6 is fixed in the mounting hole by bearing cap 7, prevent bearing 6 from
Skidded off in the mounting hole.
In addition, the other end of the support shaft 5 is bolted with stop nut 8, close to the bearing cap of the stop nut 8
7 are spaced with the stop nut 8.Stop nut 8 is used for backstop support shaft 5, it is to avoid support shaft 5 is skidded off from bearing 6, special
It is not to avoid support shaft 5 from being moved axially towards secondary mass 3, and stop nut 8 keeps interval to be in order to avoid branch with bearing cap 7
Support and produce friction between stop nut 8 and bearing cap 7 when axle 5 rotates.
In addition, the two ends of the support arm 41 are connected to the bottom for being removably installed in the engine 1
Seat 42.As shown in Fig. 2 base 42 is used to support support arm 41, base 42 extends from engine 1 towards gear box position so that
Suitable spacing is kept between support arm 41 and secondary mass 3.
Further, prominent keeper is formed with the engine 1, the keeper is inserted into the base
In 42.Base 42 and the keeper be it is detachably connected, can be by frictional force between the keeper and base 42
Link together.
Further, as shown in figure 3, the keeper is speed changer positioning sleeve 9, the base 42 is towards the engine
It is formed with 1 end face in positioning hole, the positioning hole and is provided with spacer 10, the speed changer positioning sleeve 9 is removably inserted into institute
State in spacer 10.Support 4 can utilize the structure for being used to connect speed changer of engine 1 to realize installation, and speed changer positioning sleeve 9 is used
In installing speed changer, support 4 is connected to speed changer positioning sleeve 9 by base 42 and realizes installation, can be by mounting bracket 4
Support shaft 5 is aligned in the central shaft hole of secondary mass 3, and speed changer positioning sleeve 9 is aligned in into corresponding spacer 10, Ran Houchao
Promote support 4 to realize to engine to install.Spacer 10 is dismountable part, is conveniently replaceable.It is of course also possible to by other knots
Support 4 is simultaneously removably installed in engine 1 by structure using other modes, and the mode being for example bolted pacifies support 4
It is attached to engine 1.
The foregoing is only better embodiment of the present utility model, not to limit the utility model, it is all
Within spirit and principle of the present utility model, any modification, equivalent substitution and improvements made etc. should be included in this practicality new
Within the protection domain of type.
