Abstract
The utility model provides a caliper core shaft which comprises a mandrel, a bearing and a mandrel nut, wherein a retaining ring is sleeved on the mandrel; the bearing is sleeved on the mandrel and arranged at one side of the retaining ring; the mandrel nut is sleeved on the other end of the mandrel and is provided with a mandrel thread; two sides, which take the retaining ring as a boundary, of the mandrel are different in diameter; the mandrel nut comprises a sleeve and a gear arranged on the top end of the sleeve; the sleeve is internally provided with a sleeve thread; and the sleeve thread and the mandrel thread are matched. According to the caliper core shaft, the mandrel nut is sleeved on the mandrel by virtue of the thread which is a mechanical self-locking thread, the maximal clamping force is 17+/-2KN, and the performance of the prior art is improved.
Description
Technical field
The utility model relates to a kind of brake device for car, particularly a kind of clamp mandrel.
Background technology
Electronic brake, (Electrical Parking Brake, electronic brake system) refers to replace traditional manual parking system to be installed on the vehicle by the technology of electronic control mode realization stopping brake, the long-term traditional hand braking during standstill pattern of using has been advanced major step.The electronic brake system system is by an electronic control unit, and switch and two effect devices are implemented action, after two effect devices are contained in respectively two on the calipers assembly and can directly directly apply braking force on trailing wheel.It not luminous energy replace traditional parking brake to finish parking function, auxiliary brake function can also be provided, slow down with the minimum deceleration degree greater than laws and regulations requirement when allowing driving, electronic brake system also has many functions with satisfy regulatory and functional requirement.Present employed clamp can't adapt to the demand of present automobile.
