Description
Technical field
The invention belongs to technical field of engines, relate to a kind of engine structure, particularly to a kind of balance shaft of engine intermittent running structure.
Background technology
Along with the development of society, energy problem has become as the country and people's focus of attention problem.And along with growth in the living standard, the automobile of China recoverable amount per capita is more and more higher, how to reduce automobile energy consumption, reach the purpose of energy-conserving and environment-protective, be the strategic problem of automobile production enterprise.Automobile energy consumption mainly produces in electromotor, and the energy consumption the most how reducing electromotor is to reduce the important starting point of automobile entirety energy consumption.In engine operation process, balance axle directly relies on gear or driving-chain is connected with bent axle, bent axle drive；Balance axle operates according to certain gear ratio with the rotation of bent axle all the time in this process, goes to balance the vibration of electromotor difference Jie time；Owing to electromotor is under different operating modes, varying in size of each time vibration that is situated between, and under the Part load of high engine speeds operating, electromotor self vibration is little, balance axle goes to get involved the vibration of balanced engine not necessarily, can cause the waste of electromotor output work on the contrary.
Summary of the invention
It is an object of the invention to solve the balance axle of traditional electromotor all the time with crank rotation, under the Part load of high engine speeds operating, balance axle gets involved the vibration of balanced engine not necessarily, the problem that can cause the waste of electromotor output work on the contrary, it is provided that a kind of balance shaft of engine intermittent running structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of balance shaft of engine intermittent running structure, including the bent axle be arrangeding in parallel, balance axle, described balance axle is provided with drive, described drive uses bearing to be rotatably connected with balance axle, bent axle is rotated by the drive on Chain conveyer or gear drive band dynamic balancing axle, connect, also by spline, the axle that is slidably connected on balance axle, the axle that is slidably connected can slide axially along spline and realize and the combination of drive and separating, and described electromotor is additionally provided with the executor driving the axle that is slidably connected to slide.When engine luggine is less, now getting involved and carry out vibration balancing without balancing axle, utilize the driver axle that will be slidably connected to separate with drive, drive dallies with bent axle, and balance axle stops operating, reduce electromotor at the kinetic equation loss balanced on axle.When engine luggine is relatively big, when needing balance axle intervention to carry out vibration balancing, driver promotes the axle that is slidably connected to be combined with drive, is that balance axle is transmitted wheel drive rotation, gets involved engine luggine balance.
As preferably, described in the axle that is slidably connected towards the front end face of drive, lock pin is set, drive rear end face and lock pin are correspondingly provided with the locking gathering sill of arc, the degree of depth of locking gathering sill along drive rotation direction from deeply seamlessly transitting to shallow.Be slidably connected axle during drive combines, the axle rotating speed that is slidably connected experiences from being not rotated to the process identical with drive rotating speed, lock pin enters from the shallow end of locking gathering sill, drive the axle that is slidably connected to rotate first with frictional force, the axle that makes to be slidably connected progressively accelerates, until lock pin slides into the deep end of locking gathering sill, the side of lock pin abuts to the cell wall of locking gathering sill deep end, and the axle that is slidably connected reaches Tong Bu with drive.The setting from shallow to deep of the locking gathering sill extends the axle acceleration time that is slidably connected, it is to avoid produce excessive impact when combining.
