AI Technical Summary
Technical Problem
In existing pressure-building pumps, the connection strength between the sleeve and the base is insufficient, making it prone to misalignment, which affects the piston's guidance and makes installation difficult, thus impacting the overall assembly.
Method used
By setting a groove on the base and rigidly connecting the sleeve to the base, the sleeve is inserted into the groove. Combined with elastic snap-fit parts and bearing outer rings, a stable connection between the sleeve and the base is ensured, reducing installation difficulty.
Benefits of technology
It improves the assemblability and stability of the pressure-building pump, reduces installation difficulty, and enhances the overall structural stability.

Abstract
The utility model provides a pressure buildup pump, a brake system and a vehicle. The pressure buildup pump comprises a base and a sleeve. The base is provided with a sinking groove, the base is at least partially constructed to form a hydraulic cavity, and the hydraulic cavity is communicated with the sinking groove. The sleeve at least partially extends into the sinking groove so as to guide the piston assembly to move at least partially in the hydraulic cavity, and the sleeve is rigidly connected with the base. The pressure buildup pump has the effect of being good in assembling performance.
