Disclosed is an autonomous driving vehicle including a front wheel support connected to a front wheel as one body and supporting the front wheel, and a knuckle arm angle adjustment assembly having one side to which a knuckle arm is connected, the knuckle arm moving with the front wheel during steering the front wheel, and knuckle arm angle adjustment assembly being coupled to one side of the front wheel support to be capable of angle adjustment for setting an inclination angle of the knuckle arm.

Disclosed is a corner module apparatus for a vehicle. The corner module includes a knuckle coupled to a wheel bearing rotatably supporting a wheel, a drive motor, configured to generate a drive power, spaced a distance away from the wheel, a transfer shaft, disposed between the wheel and the drive motor, configured to transfer the drive power generated from the drive motor, a suspension connected to the knuckle and configured to absorb shock transferred from a road surface, and a steering system configured to support the drive motor and the suspension and to adjust a steering wheel of the wheel.

A drive device for an electric truck includes drive unit housings provided to each of drive wheels on left and right sides of the electric truck, each of the drive unit housings integrally accommodating a motor that generates drive power, a reducer that reduces a rotation speed of the motor, and a final gear that is connected to the reducer and transfers the drive power of the motor to the drive wheel. The drive device further includes suspension parts one provided over the final gear in each of the drive unit housings, steering gear parts one being provided over each of the suspension parts, pairs of hinge parts, and pairs of body-connecting parts, one of the pairs connecting each of the steering gear parts to a vehicle body of the electric truck through each of the pairs of hinge parts.

A vehicle includes an assembly for providing suspension and steering for a wheel. The assembly includes an inner knuckle and a steering knuckle. The inner knuckle is coupled to an upper control arm at an upper joint and a lower control arm at a lower joint, forming a double wishbone suspension. The upper joint and the lower joint define a first axis. The steering knuckle is coupled to the inner knuckle at a steering joint that forms or otherwise defines a kingpin axis. The steering joint includes a revolute joint, a ball joint, or both. The steering knuckle is configured to be engaged with a tie-rod coupled to a steering mechanism. The kingpin axis is nearer a center of the wheel than the first axis, thus preventing or otherwise limiting torque steer. The upper and lower joints are constrained from significant steering rotation by suitable bushings, anti-steer arms, or both.

A corner module apparatus for a vehicle includes a driving unit configured to provide driving power to a wheel of the vehicle; a braking unit, coupled with the driving unit, configured to apply or release braking power; an upper arm module, connected to the driving unit, adjustable to vary a camber angle of the wheel; a lower arm module, connected to the driving unit, configured to absorb road surface impact while the vehicle moves; and a steering unit configured to support the upper arm module and the lower arm module, and adjust a steering angle of the wheel.

A milling machine may have a frame, a milling drum attached to the frame, and ground engaging tracks that support the frame and propel the milling machine in a forward or rearward direction. The milling machine may have height adjustable actuators connecting the frame to the tracks. Each actuator may have a cylinder attached to the frame, a piston slidably disposed within the cylinder, and a rod connected at a first end to the piston and connected to a track at a second end. The milling machine may have a tank storing hydraulic fluid and a fluid conduit connecting the tank to the cylinder. The milling machine may have a control valve selectively controlling a flow rate of the hydraulic fluid in the fluid conduit. The milling machine may also have a controller that determines a height of the frame relative to the ground surface based on the flow rate.

An electric truck includes drive units being provided to each of driving wheels on left and right sides of the electric truck, each of the drive units transmitting a driving force of a motor to each of the driving wheels, a body frame casing including a pair of mounting frame bodies extending in a vehicle width direction of the electric truck and being arranged apart in a vehicle front-rear direction and a pair of cross members connecting the pair of mounting frame bodies, and body-connecting parts connecting each of a vehicle front side and a vehicle rear side of each of the drive units arranged in a frame of the body frame casing to each of the mounting frame bodies. The pair of drive units are arranged so as to be adjacent to each other in the vehicle width direction inside the frame of the body frame casing.

A drive device for an electric truck provided with double-tires, the drive device including drive units provided to each of the double-tires on left and right sides of the electric truck, each of the drive units including a drive unit housing integrally accommodating a motor that generates drive power, a reducer that reduces a rotation speed of the motor, and a final gear that is connected to the reducer and transfers the drive power of the motor to a drive shaft of the double-tire. The drive device further including suspension parts one integrally integrated with above the final gear in the drive unit housing of each of the drive units and steering gear parts one integrally integrated with above each of the suspension parts and being configured to be steerable the double-tire.

A trailer for towing by a power vehicle is provided and generally includes a frame and a tandem wheel assembly. The frame forms an undercarriage chassis which the tandem wheel assembly is positioned there under. The undercarriage chassis includes a steerable rear wheel assembly, a steerable front wheel assembly, and an extension assembly moving the front wheel assembly between trailing position and a self-propelled position where the rear wheel assembly and the front wheel assembly are positioned to equally support the undercarriage chassis.

A wheel steering device for a vehicle, including: a steering knuckle that constitutes a part of a suspension device and that is capable of moving relative to a body of the vehicle in an up-down direction, the steering knuckle holding a wheel such that the wheel is rotatable; and a steering actuator configured to cause the steering knuckle to be pivoted about a kingpin axis so steer the wheel, wherein a caster angle and a caster offset are both 0.
