Background technique
Such as dumper, concrete mixer special-purpose vehicle, it is upper dress apparatus for work power when by gearbox side install additional one
A power takeoff is commonly called as the systems work such as side power takeoff band hydrodynamic pressure.But this power takeoff is subject to conditions, torque is relatively
It is small, it can accomplish 100-20N.m under normal circumstances, the power body side-draw product big structure of large torque is complicated, therefore works as and need large torque
When, all it is to increase an engine in upper dress, is commonly called as " assistant engine ", referred to as " pair hair ", but since assistant engine post-processes
Difficulty, discharge cannot reach V discharge standard of state, therefore in V and of the states of enforcement such as current special-purpose vehicle, sanitation cart, Special work vehicle
Under the conditions of VI discharge standard of state, need from sustainer power taking, this device position Full-power takeoff from sustainer power taking.
Full-power takeoff torque is big, can achieve 500,600N.m, even up to 1000N.m or more, is that solution is dedicated
Vehicle, sanitation cart emission control reduce the repacking most effective measure of cost.But existing Full-power takeoff is essentially all direct
Output power, can not carry out dynamic clutch, i.e., cannot accomplish to engage output power at any time when driving, separate cut at any time
Disconnected power, therefore it is unfavorable for saving fuel oil there is also certain energy consumption when not needing power output.Therefore, it is desirable in vehicle
It can engage and separate — that is, dynamic clutching power takeoff at any time as needed in driving process.
Our company has applied for multiple dynamic clutch power takeoff patents, as ZL201620691789.4 is a kind of novel dynamic
A kind of dynamic engaging power transfer device of state clutching power takeoff device, ZL201720136761.9, has been put into use, effect compared with
Well, when but occurring vehicle variable working condition state in use, i.e., engine is suddenly from the slow-speed of revolution in power takeoff work
It is substantially improved, and product failure problem in loading process is significantly increased suddenly at high speed.From structural analysis main problem
It is that the transmission shaft of output end connection has biggish radial force to power takeoff output shaft, keeps clutch friction spoke not parallel, it is practical
Torque ratio theoretical torque is less than normal, and in variable working condition, required torque increases suddenly, causes to lose at the abrasion of friction spoke, fever
Effect.
