Synchronous load simulating device for double output shafts of scooter drive axle

A synchronous load simulating device for double output shafts of a scooter drive axle, which is characterized by comprising a bottom plate, wherein each of a left side and a right side of the bottom plate is provided with a fixed plate, each of lower portions of the fixed plates forms a left-right through first fixed hole and is provided with a first bearing in a matching manner, a transmission shaft is fixed to the fixed plate through the first bearing, each of two ends of the transmission shaft passes through one fixed plate and is fixedly provided with a lower transmission gear, each of upper portions of the fixed plates forms a left-right through second fixed hole and is provided with a second bearing in a matching manner, each second bearing is fixed to a movable shaft, one end of the movable shaft is located between the two fixed plates and is matched with a first coupler, the other end of the movable shaft passes through the fixed plate and is fixedly provided with an upper transmission gear, each upper transmission gear is engaged with one lower transmission gear, the movable shaft has an accommodating groove formed in an axial direction of the movable shaft, the accommodating groove extends to one end away from the first coupler and runs through an axial end face of the movable shaft, an adjusting rod is disposed in the accommodating groove, one end of the adjusting rod extends to a radial outer side to form an adjusting rod boss, the other end of the adjusting rod extends to an outer side of the movable shaft, an end socket is fixed to a groove opening position of the accommodating groove of the movable shaft, the end socket has a clearing hole for the adjusting rod to pass through, the adjusting rod is sleeved with a compression spring, one end of the compression spring urges the adjusting rod boss, the other end of the compression spring urges the end socket, the movable shaft forms a first groove and a second groove running through a radial inner wall and a radial outer wall of the movable shaft, the first groove is formed in the axial direction of the movable shaft, an acute included angle is formed by the second groove and the first groove, one end of the second groove is oppositely located between two axial ends of the first groove, the other end of the second groove extends to a side of the upper transmission gear and is connected with one end, close to the upper transmission gear, of the first groove, the adjusting rod boss is fixed to a positioning pin, the positioning pin passes through the first groove or the second groove so as to be fixed to the first coupler, a second coupler is detachably fixed to each of the two output shafts of the drive axle, and the second coupler is used for being in linkage with the first coupler;

• the drive axle is placed between the two fixed plates, when the positioning pin is located in the first groove, under the effect of the compression spring, the adjusting rod is pushed so as to drive the first coupler to move towards the second coupler, and when the positioning pin is located in the second groove, under the effect of the compression spring, the positioning pin is pushed to one end, away from the upper transmission gear, of the second groove, and the second coupler and the first coupler are separated from each other.
