Description
Technical field
The utility model relates to technical field of engines, in particular to a kind of crankshaft-flywheel group and the crankcase and the motor that comprise it.
Background technique
At present, for the motor that the fields such as automobile use, its rotating speed, generally all at more than 4000r/min, usually all adopts and installs a trunnion shaft or balancer weight additional to balance the first order reciprocating inertia force square.Higher motor is required for some, in order to thoroughly balance reciprocal inertia force square, except laying except balancer weight on bent axle, also needing in addition to lay two trunnion shafves, forming one group of two-shaft balancing device.Therefore, for motor, if good counterbalance effect will be obtained, usually need to adopt the more complicated uniaxiality balance method of structure or more complicated double-shaft balance method to realize.
But, along with current global environmental pollution is day by day serious, resource is in short supply gradually, and Consumer and legislator are also more and more higher for reducing the requirement of CO2 emission, and three cylinder machines are that the novel motor of representative replaces four-cylinder thus gradually and motor as main flow uses.
In three cylinder machines, three cylinder machines in upright arrangement also exist the imbalance of intrinsic centrifugal inertia force square, the first order reciprocating inertia force square and two-stage reciprocating inertia force square, so usually also all need to take certain balanced measure.But due to the restriction of body spatial position, often can not use conventional methods and install trunnion shaft additional or increase the balance requirement that appropriate balancer weight carrys out satisfied three cylinder machines.Simultaneously, although trunnion shaft is a kind of mode for improvement of equilibrium problem, its driving can cause new acoustic problems, application particularly in turbosupercharging three cylinder engine, bent axle meeting High Rotation Speed and trunnion shaft carry out gear transmission, the acoustic problem produced is just more obvious, and increases trunnion shaft and also can cause extra weight, and trunnion shaft also can cause the increase of friction problem and manufacture cost.
Model utility content
Given this, the utility model provides a kind of turbulence device of vehicle and comprises its vehicle, is intended to solve in prior art on bent axle, installs installing space that trunnion shaft and balancer weight bring and noise, weight, friction and the manufacture cost problem in these.
An aspect, the utility model provides a kind of crankshaft-flywheel group, comprises bent axle, flywheel and belt pulley, and the wheel side of this belt pulley, wheel shoulder and/or wheel face are provided with weighting unit, and this flywheel is provided with loss of weight unit.
Further, above-mentioned weighting unit complies with belt pulley circumferentially.
Further, above-mentioned weighting unit is the bump body on belt pulley.
Further, above-mentioned bump body is block.
Further, above-mentioned loss of weight unit is located at the wheel side of flywheel.
Further, above-mentioned loss of weight unit complies with flywheel circumferentially.
Further, above-mentioned loss of weight unit is the through hole on flywheel.
Alternatively, above-mentioned loss of weight unit is the cell body on flywheel.
Again on the one hand, the utility model additionally provides a kind of crankcase, comprises casing, is also provided with above-mentioned crankshaft-flywheel group in this casing.
Again on the one hand, the utility model additionally provides a kind of motor, comprises engine main body, and it also comprises above-mentioned crankcase.
The crankshaft-flywheel group that the utility model provides, by arranging weighting unit over pulleys carried, flywheel arranges loss of weight unit, namely gain in weight over pulleys carried, on flywheel, reduce weight simultaneously, thus substitute traditional practice installing trunnion shaft and balancer weight on bent axle additional, make bent axle also can balancing inertia moment under the prerequisite not adopting trunnion shaft and balancer weight, effectively fundamentally improve the vibration source of automobile, to reach vibration damping, noise reduction, raising automobilism stationarity, the object that alleviates car weight and reduce costs.Meanwhile, compared to the practice installing trunnion shaft and balancer weight additional, the body space that can overcome again the motors such as three cylinder machines limits the installation of bent axle, and solves the problem of noise, weight, manufacture cost and the friction aspect that trunnion shaft brings.
The crankcase that the utility model provides in addition and motor, owing to have employed above-mentioned crankshaft-flywheel group, therefore possessed aforesaid advantage equally, do not repeated them here.
Accompanying drawing explanation
By reading hereafter detailed description of the preferred embodiment, various other advantage and benefit will become cheer and bright for those of ordinary skill in the art.Accompanying drawing only for illustrating the object of preferred implementation, and is not thought restriction of the present utility model.And in whole accompanying drawing, represent identical parts by identical reference symbol.In the accompanying drawings:
The structural representation of the crankshaft-flywheel group that Fig. 1 provides for the utility model embodiment;
The structural representation of the belt pulley in the crankshaft-flywheel group that Fig. 2 provides for the utility model embodiment;
The structural representation of the flywheel in the crankshaft-flywheel group that Fig. 3 provides for the utility model embodiment.
Embodiment
Below with reference to accompanying drawings exemplary embodiment of the present disclosure is described in more detail.Although show exemplary embodiment of the present disclosure in accompanying drawing, however should be appreciated that can realize the disclosure in a variety of manners and not should limit by the embodiment that sets forth here.On the contrary, provide these embodiments to be in order to more thoroughly the disclosure can be understood, and complete for the scope of the present disclosure can be conveyed to those skilled in the art.
Crankshaft-flywheel group embodiment:
See Fig. 1 to Fig. 3, there is shown the preferred structure of the crankshaft-flywheel group that the utility model embodiment provides.This crankshaft-flywheel group comprises bent axle 1, flywheel 2 and belt pulley 3, the present embodiment illustrate only the structure of more representative crankshaft-flywheel group in a kind of prior art, crankshaft-flywheel groups more of the prior art also may make accommodation on the basis of these three parts, but all using these three parts as basic; Thus, it will be appreciated by those skilled in the art that, other crankshaft-flywheel group structure all should belong to the utility model for structure, illustrate no longer one by one at this and repeat; As the improvements to this structure, be mainly, belt pulley 3 is provided with weighting unit 4, and flywheel 2 is provided with loss of weight unit 5.
The crankshaft-flywheel group that the present embodiment provides, by arranging weighting unit over pulleys carried, flywheel arranges loss of weight unit, namely gain in weight over pulleys carried, on flywheel, reduce weight simultaneously, thus substitute traditional practice installing trunnion shaft and balancer weight on bent axle additional, make bent axle also can balancing inertia moment under the prerequisite not adopting trunnion shaft and balancer weight, effectively fundamentally improve the vibration source of automobile, to reach vibration damping, noise reduction, raising automobilism stationarity, the object that alleviates car weight and reduce costs.Meanwhile, compared to the practice installing trunnion shaft and balancer weight additional, the body space that can overcome again the motors such as three cylinder machines limits the installation of bent axle, and solves the problem of noise, weight, manufacture cost and the friction aspect that trunnion shaft brings.
See Fig. 2, as further improvement, weighting unit 4 specifically can be located at the wheel side of belt pulley 3, compared to the wheel face being located at belt pulley 3, can make weighting unit 4 to be set on belt pulley 3 after can not affect proper engagement and the running of belt pulley 3 and belt.Certainly, according to demand, weighting unit 4 can be located at the wheel face of belt pulley 3, wheel shoulder or other position equally, or weighting unit 4 be located at simultaneously wheel side, wheel face or wheel shoulder wherein two upper or three on arrange simultaneously.
