Abstract: PROBLEM TO BE SOLVED: To enlarge as much as possible the axial dimension of a chamfer on at least one end side of an outer ring while ensuring the fit between the outer ring of a self-aligning roller bearing and a housing in a load area.SOLUTION: The connection line E between the outer diameter surface 12 of the outer ring 1 and the chamfer 15 is placed on an extension of the line of action at the maximum contact angle θ2 in a row on the chamfer 15 side. The outer diameter surface 12 of the outer ring 1 is formed up to an extension where a line of action of a resultant force of forces transferred to barrel-shaped rollers 3a by the outer ring 1 is tilted closest to the chamfer 15 side, and the axial dimension of the chamfer 15 is enlarged as much as possible. The line of action of the resultant force passes through the area where the fit between the outer ring 1 and housing 5 is secured without a gap even when the barrel-shaped rollers 3a have any value of the contact angle due to the self-aligning property in the row on the side where the chamfer 15 is made.

IPC: B60G17/015
Filed: 2010-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle body posture control system capable of enhancing turning operability, operation stability and ride comfort during vehicle traveling.SOLUTION: While a tire is in a working region during vehicle traveling, a pitch control section 23 which calculates a target pitch rate according to a roll rate takes precedence over a roll restraining section 18.

In a limited region where a road surface grip state of a tire is poor, a roll restraining section 18 takes precedence over the pitch control section 23 to weight the target damping force calculated by the roll restraining section 18. Thus, damping force characteristics of respective dampers 6, 9 are controlled to increase roll restraining controlled variables.
