The penetration rate of automobile intelligence is increased, and the application of ball screw is promoted, and the future car market space is expected to exceed 10 billion yuan. The main applications of ball screw in the car are: 1) steering: REPS adopts ball screw, and the output thrust can reach 16KN (DP-EPS maximum thrust is 12KN). 2) Parking brake: At present, the market EPB brake calipers mainly use thread and ball screw transmission, of which the ball screw has high efficiency, long life and smooth movement, but the cost is high. In the future, with the technological breakthroughs of domestic enterprises, it is expected to drive the penetration rate to increase. 3) Service brake: one box and EMB products will use ball screws, and the future penetration will promote the application of roller screws. 4) Others: Ball screws are also expected to be used in seats, sliding doors, and high-end shock absorption systems.
Overall, the future value of automotive ball screw bicycles is expected to reach 1,000 yuan, and the car end ball screw market is expected to exceed 10 billion yuan. If you consider the use of seats, sliding doors, suspension and other fields + for safety redundancy, the spare parts also use ball screws, then the value of the ball screws will be higher.
