Description

A kind of powershift device

[technical field]

The utility model relates to a kind of device of mechanical field, relates in particular to a kind of powershift device.

[background technique]

In some equipment of mechanical field, being example from running type load hauling car: from running type load hauling car generally by the chassis that is provided with operator cabin, be located at the casing on this chassis, motor, the engine speed changer that is connected with this motor, power-measuring system, composition such as control cabinet and generator set, wherein, power-measuring system is by the transfer case that connects by transmission shaft successively, power measurer speed changer and power measurer are formed, this transfer case and engine speed changer, ransaxle on the load hauling vehicle chassis connects respectively, this power measurer is connected in control cabinet, control cabinet can produce needed moment of torsion and rotating speed in order to measure and to control power measurer, thereby guarantee that the load hauling car produces certain load hauling power, and the related data of record process of the test;

Generally can carry out two kinds of operations from running type load hauling car, a kind of is only to cross journey (promptly other vehicles not being carried out test job) voluntarily, and another kind is that other vehicles are carried out test job; In the prior art, when only crossing the operation of journey voluntarily, the operator needs engine speed changer is put into gear to guarantee that engine speed changer combines with transfer case, meanwhile, the operator need remember that the power measurer speed changer is hung neutral transfers to power measurer to avoid part power by the power measurer speed changer, promptly cut off transfer case to the connection between the power measurer, to avoid because of turn round the simultaneously shortening of service life of equipments such as the power waste that causes and power measurer of power measurer, follow ato unit, power is successively via motor, engine speed changer, transfer case is passed to the ransaxle on the chassis, the wheel of the load hauling of ransaxle driving afterwards car is rotated, and realizes advancing and reverse motion of load hauling car; When the load hauling car is used for that other vehicles are carried out test job, need earlier engine speed changer to be hung neutral to interrupt the power of motor input, and guarantee that the power measurer speed changer is to be in the state of putting into gear, the wheel of load hauling car is in the drive backspin of the tested vehicle lively power of changing the line of production afterwards, then the power of wheel generation is by ransaxle transmission and transfer case, transfer case is transferred to power measurer with power by the power measurer speed changer, control cabinet is measured and is controlled required moment of torsion of power measurer running this moment and rotating speed etc. then, thereby produce the rotation that certain load hauling power is used for hindering wheel by power measurer, to realize braking to wheel.

From the above, finish the load hauling car other vehicles are carried out test process to the mutual conversion of only crossing journey voluntarily, need putting into gear of taking turns respectively of engine speed changer and power measurer speed changer and hang neutral, complicated operation is loaded down with trivial details, misoperation appears easily, therefore, a kind of device that can be used for improving this present situation of design is very necessary.
