It is widely used ona lotof tractors at present, pleted car performance of the vehicle , right oil economy ,etc. greatly . At present, domestic automobile gearbox test a lot platform or traditional type, automatic degree relatively low, because the hydraulic pressure mechanical drive gearbox structure plicated, maintain technology to expect much, only very difficult by the traditional maintenance method to guarantee to maintain quality , need adapting to the new-type gear box that the pany uses and maintaining the checkout equipment , in order to improve the maintenance quality of the mechanical drive gearbox of the hydraulic pressure , guarantee its performance . This subject designs the new-type experimental platform of gearbox that a kind of adaptation pany uses to this gearbox - Opening type experimental platform of mechanical drive gearbox of the hydraulic pressure. It can provide motive force , the introduction operating mode on the automobile of gear box of simulation for new-type gearbox ; Can load the gear box , measure the automobile and accelerate performance ; Can change double-current the shelf law and hydraulic pressure machinery to shunt to measure more than ,etc. performance , to the transmis
