Problems solved by technology

However, in this case, in the low-speed region, the rudder angle difference between the left and right wheels is insufficient, the rudder angle of the outer wheel is too large, and in the high-speed region, the rudder angle of the inner wheel is too large
If the tire lateral force distribution of the inner and outer wheels has an unnecessary deviation like this, it constitutes a cause of deterioration of fuel consumption due to deterioration of running resistance and early wear of the tires. In addition, the inner and outer wheels cannot be effectively used, and thus, There is a problem that the smoothness of turning is impaired

Abstract

This hub unit (1) equipped with an auxiliary steering function is provided with: a hub bearing part assembly component (2) provided with a hub bearing (15) for supporting a wheel; and an actuator (5)for auxiliary steering. The hub bearing part assembly component (2) is installed on a knuckle (6), i.e. a unit support member of a suspension device, via upper and lower rotation-permitting support components (4, 4) in two places, so as to be capable of rotating around an auxiliary steering axis (A) extending in the vertical direction. The actuator (5) for auxiliary steering is installed on the knuckle (6), and allows the hub bearing part assembly component (2) to rotate around the auxiliary steering axis (A).

Description

[0001] related application [0002] This application claims the priority of the application dated September 27, 2017, and the application number is JP Japanese Patent Application No. 2017-186441, and by referring to the entirety, this is incorporated as a content constituting a part of this application. technical field [0003] The present invention relates to a hub unit with a steering function and a vehicle having an auxiliary steering function to be added to steering based on steering. The present invention relates to a technique for improving running stability and safety of a vehicle. Background technique [0004] Because in ordinary vehicles, the steering wheel and the steering device are mechanically connected, and in addition, the two ends of the steering device are connected to the left and right wheels through tie rods, so the cut angles of the corresponding left and right wheels are determined by the action of the steering wheel according to the initial settings. S...
