The present invention relates to a steering function-equipped hub unit (1) having a function of steering a rear wheel, the hub unit including: a hub unit body (2) having a hub bearing (15) configured to support the rear wheel (9R); a unit support member (3) rotatably supporting the hub unit body (2) about a turning axis (A) extending in a vertical direction, the unit support member being configured to be provided to a rear-wheel suspension (Rs); and a steering actuator (5) configured to rotate the hub unit body (2) about the turning axis (A).

A vehicle for transporting a passenger in a standing position includes a frame, a rear axle assembly disposed at a rear end of the frame, a front suspension assembly disposed at a front end of the frame, a rear deck attached to the frame to accommodate a trailing foot of the passenger, a front deck attached to the frame to accommodate a leading foot of the passenger, and a driveshaft extending forward from the rear axle assembly such that the driveshaft transmits power to the rear axle assembly.

An automotive component manufacturing method includes a molding process of pressing a portion of a hollow tube formed from a metal material, or a composite material including a metal and a resin, so as to deform the portion of the hollow tube, from a tube outer side toward a tube inner side, to beyond an axial center of the hollow tube, and mold the portion of the hollow tube into a deformed section deformed with a concave profile; and a deformation process of deforming a location having a high level of residual stress in a closed cross-section configured by the deformed section so as to deform the location out-of-plane.

The invention relates to an assembly (1) of a frame member (2) for an electric vehicle comprising a transverse member (14) with at each end a housing (10,10) connected to the transverse member (14) and two in-wheel motors (3,3) connected to a respective housing. Each motor comprises a brake drum (35) connected to a rotor (24), extending coaxially within the housing (10,10) near an inner surface a circumferential wall (8) of the housing. A brake shoe assembly (51,52,55,56) is movable in a radial direction R against the brake drum (35), and an actuator (18,18) is placed on an outer surface (17,17) of the circumferential wall (8,8) of the housing (10,10), connected to the brake shoe assembly (51,52,55,56). The assembly provides a low-floor portal frame member, with two in-wheel motors and a brake system that has relatively small axial dimensions and provides a reduced space envelope at the vehicle side.

This torsion beam manufacturing method is a method for manufacturing a torsion beam which is provided with a uniformly shaped closed cross-sectional portion in which a cross section orthogonal to a longitudinal direction is a closed cross section having a substantial V-shape or a substantial U-shape with a pair of ear portions, and a shape changing portion which leads to the uniformly shaped closed cross-sectional portion and in which a shape of the closed cross section changes progressively away from the uniformly shaped closed cross-sectional portion, the torsion beam manufacturing method comprising: thickening to form a pair of thickened portions in at least the shape changing portion by pressurizing each of the pair of ear portions from outside against swelling of the pair of ear portions in a slate where both outer surfaces of each of the pair of ear portions are supported.

This axle beam is provided with a pair of horizontal plate sections separated vertically from and facing each other; and a vertical plate section extending vertically so as to connect intermediate sections, in a front-rear direction, of the pair of horizontal plate sections. The horizontal plate section on the upper side has a forwardly extending upper front plate section and a rearwardly extending upper rear plate section, and the horizontal plate section on the lower side has a forwardly extending lower front plate section and a rearwardly extending lower rear plate section. One of the upper front plate section, the upper rear plate section, the lower front plate section, and the lower rear plate section is set to have a smaller length in the front-rear direction than the other three plate sections, and among the other three plate sections, the two plate sections which are separated vertically from and facing each other are set to have substantially the same length in the front-rear direction.

Provided are a suspension bush and a suspension device that are able to achieve both steering operability and stability of a vehicle at the time of turning. A projection portion is formed on the outer circumference of an inner cylinder. A guide is formed on the inner circumference of an outer cylinder. In the guide, a slit is formed along an extending direction that includes: a component, in a parallel direction, which runs parallel with an axial line; and a component in a circumferential direction around the axial line. The projection portion is disposed in the slit, and a threaded mechanism is formed by the projection portion and the slit.
