Description
Technical Field
The invention relates to the field of mechanical testing, in particular to a durability reciprocating loading device of an electric booster, which is used for detecting the durability of the electric booster and providing reciprocating loading force for the electric booster.
Background
The electric booster is a motor pushing the main cylinder piston, which senses the force and speed of the driver stepping on the brake by using a sensor, transmits the processed signals to the ECU, and then controls the motor in the electric booster to push the main cylinder to work under the drive of the electromechanical amplifying mechanism, thereby realizing the electric control brake.
Because service braking is a concern for the life and property safety of the driver and passengers, detection of the braking system has been very strict. For the newly emerging electric booster, the safety and reliability are particularly important, so that the durability test is indispensable.
The durability test process of the electric booster needs a reciprocating loading mechanism, and a cylinder is usually used for loading motion, for example, a pedal durability test device (CN 102364318A) is applied by a Xujingsu state institute of Xujingku, and two pedals are simultaneously subjected to durability test through a double-shaft compound cylinder, but the cylinder cannot meet the control of multiple limiting points, can only load full stroke and cannot meet the adjustment of displacement freedom, and for the electric booster, the electric booster needs to simulate any stroke of stepping a brake of a real vehicle. The invention has two stages of loading mechanisms, the loading position is limited by using the servo motor loading mechanism, the cylinder executing mechanism performs loading motion, and the first stage of stroke adjustment is realized by the adjustment position of the servo motor loading mechanism. The servo motor loading mechanism controls the position of the executing mechanism according to the estimated stroke of the user, and stepless adjustment is realized.
