In addition, said drum (20) is combined by fixing the each screw groove centerline axis (RA) on rotating through all restraint, said hub (10) inner coupled to 1 generation taper bearings (11) after the lower end of the hub portions located outside load point (LP) toward on restraining substrate.

Said, operation conditions brake system (100) number 1 and number 2 applying the operating state is the operating state is applying the entire hub and drum connected to the chamber.

The operating state of a vehicle tire and moving said number 1 depending on the direction and impact forces exerted on the various steering in a direction brake system 5 to by analysis and calculated based on the conditions, specifically the same fixed time stored in both axial tire number 1 situation, one tire pressure of the tire is the same time stored in fixed axial situation number 2, number 3 detects the curb and leading the 10 front tire contact with the situation, said lateral concave section number 4 stores and vehicle tire in contact through the curb into a consists of number 5.

In addition, the operating state is said number 2 simple fall, turning, into a special transverse load is consists of 3.

The operating state is said number 2 the hub (10) and said drum (20) support and impact force applied in a direction various analyzing 3 calculated based on the conditions and, specifically simple fall, turning, special cross load 3 consists of the conditions.

Wherein only the chin upon movement of simple dropped due, vertically load status generated by the burner head, by the rotation of the tire upon movement of a motor vehicle turning a status generated on the load, load application of an alkali-soluble novolak use special cross load force is greater than each situation thus set to the combustion chamber.

The load applied to the axis from being dropped due in simple (WL) analyze, lateral load force is applied to the axis of turning and special (WL) and horizontal-(BL) in composite load is equal to analyzing.

The, said axis corresponding to a center of the vehicle (WL) upwards as the axis of rotation of a vehicle tire, vehicle left-right direction of the vehicle toward the center of the axis of rotation transverse (BL) corresponding substrate.

Through and mobile of vehicle brake system (100), said hub (10) and said drum (20) amd and impact force applied respectively can be within the range taking into account the situation.

In addition, the load conditions said drum (20) gravity acceleration applied to 0. 6G, 0. 8G 1. 0G 3 conditions of a new substrate.

In said analysis step (S30) (S20) finite element analysis (FEM) set in said setting information using said hub (10) on said drum (20) determined its position calculating stress applied to the highest stresses and excessive stress strain generation is checked as follows.

Thus, when the operating state is in wide variety of environments and conditions by the impact and load said hub (10) and said drum (20) and determining a location highest stress applied to an optimum design can be.

In addition, said hub (10) on said drum (20) can be judges its position to the highest stresses, in terms of the finite element analysis as follows.
