The production method includes a first step, a second step and a third step. In the first step, a steel material is forged by dies, whereby a forged product including a rough web part and four plate-shaped rough flange parts is produced. In the second step, at least one specified rough flange part, which is at least one of the four rough flange parts, is pressed by a first die, whereby a first bent portion bending outward in an up-down direction is formed in the specified rough flange part. In the third step, the edge of the first bent portion is pressed by a second die inward in the up-down direction, whereby the edge is deformed and a second bent portion is formed. In the third step, the edge of the specified flange part is deformed while the edge is kept from deforming in a front-rear direction.

A motor drive device includes: a trailing arm that extends in a vehicle front-rear direction and includes a vehicle body-side attachment portion and wheel-side support portion, the vehicle body-side attachment portion formed on a forward portion side of the trailing arm and coupled to a vehicle body via a rubber bush, the wheel-side support portion formed on a rear side of the trailing arm and supporting a rear wheel; and a motor that is supported by the trailing arm and drives the rear wheel. The motor and the rubber bush are disposed in such a way that motor and the rubber bush are seen as being substantially aligned in a vehicle up-down direction when viewed in a vehicle width direction.

A ridgeline of a bottom surface portion at a rear portion of a rear side member rear at a rear of a fastening portion of rear side members to a rear portion of a rear suspension member is a slope shape which inclines downward toward a vehicle rear. A side member reinforcement, which is a reinforcing member which is against a toad in a vehicle length direction, is attached to the rear portion of the rear side member rear A fragile portion of low rigidity compared to a lower portion is formed at an upper portion of the side member reinforcement.

A system and method for adjusting a drivetrain comprising an e-axle on a vehicle comprises accessing route data and compressing the route data into a plurality of linearized segments. Each segment is determined by analyzing points along the route to determine when a set of route data points indicates an uphill, downhill, or flat segment. Using the segments, drivetrain configuration information for a vehicle and a weight of the vehicle, embodiments determine a performance plan that is tailored to the vehicle, including raising the e-axle to reduce rolling resistance on some segments and lowering the e-axle for some segments for increased power for acceleration, improved braking, or increased regenerative capabilities.

An omnidirectional movement system includes a frame with a central axis extending from a first end to a second end; a support extending from the first end to the second end; a first set of Mecanum wheels connected through a first axle and connected to the frame; a second set of Mecanum wheels connected through a second axle and connected to the frame; and a flexible suspension system connecting the frame to the support.

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.
