The invention relates to a vacuum booster assembly with an adjustable starting force, and belongs to vacuum booster assemblies in the technical field of automobile braking systems. A control valve component of an existing vacuum booster assembly is improved, a valve rod is sleeved with an adjusting valve rod return spring part, the adjusting valve rod return spring part is in sliding connection with the valve rod, and the front end of the adjusting valve rod return spring part is located at the front end of a valve rod boss and connected with a valve rod spring seat in an abutting mode. The adjusting nut is in threaded connection with the valve rod and abuts against the rear end of the adjusting valve rod return spring part, and the locking nut is in threaded connection with the valve rod and abuts against the rear end of the adjusting nut. The vacuum booster assembly has the advantages that the structure is novel, the starting force of the vacuum booster assembly is adjusted by additionally arranging the adjusting valve rod return spring part, the adjusting nut and the locking nut, the performance of the vacuum booster assembly is not affected, the modular standard design is adopted, the vacuum booster assembly can be applied to various types of vacuum booster assemblies, and the cost performance is good.
