Systems are provided for suspensions that deliver desirable wheel kinematics at prescribed conditions. A system includes a vehicle body structure with an engine cradle, and an associated wheel assembly. A suspension system links the wheel assembly with the engine cradle, and includes a link coupled with the engine cradle and coupled with the wheel assembly. A joint at the link includes a flange that has an opening, an edge, and at least one undercut defined in edge of the flange. The joint allows release of the wheel assembly from the engine cradle by designed tearing between the opening and the at least one undercut. The release is initiated only under loads above a select threshold at the joint, to provide select kinematics of the wheel assembly for specific operational cases.

An adjustable steering stop for an axle assembly of a vehicle includes a housing configured to be coupled to a steering knuckle or a frame of the axle assembly, a shaft received within the housing and movable relative thereto, the shaft being configured to engage a stop to limit movement of the steering knuckle relative to the frame, and a locking assembly coupled to the housing and reconfigurable between (a) an engaged configuration in which the locking assembly limits movement of the shaft relative to the housing and (b) a disengaged configuration in which the locking assembly permits the shaft to move relative to the housing. The locking assembly includes an actuator configured to reconfigure the locking assembly between the engaged and disengaged configurations. A controller is configured to control the actuator to reconfigure the locking assembly between the engaged configuration and the disengaged configuration.

A vehicle knuckle 1 includes a main body 10, a strut junction 11 that is positioned at a first side in an extending direction of an axle supported by the main body and fastens a strut damper, and an arm 12 that couples the main body to the strut junction. The vehicle knuckle has a continuous space 17 formed inside the strut junction and the arm. The arm has a first through-hole 17a on a wall 12a that couples an end 10d at the first side of the main body to the strut junction. The first through-hole is formed, with being adjacent to the end at the first side, at the side of the main body with respect to the center of a coupling position of the wall and the main body and a coupling position of the wall and the strut junction and is communicated with the space.

The disclosure provides a steering knuckle, which has good rigidity and reliability. The steering knuckle includes: a wheel support portion for supporting a wheel; a damper support portion for supporting a damper; and an arm portion for connecting the wheel support portion and the damper support portion. The damper support portion is cylindrical and has a mounting hole through which the damper is inserted, and the arm portion includes a pair of side walls connecting the damper support portion and the wheel support portion and a bottom wall connected between the side walls, and the bottom wall is connected with the side walls at the middle portion in the vertical direction of the side walls.

An autonomous tilting three-wheeled vehicle comprises a pair of front wheels coupled to a tiltable chassis by a mechanical linkage, such that the pair of wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. An electronic controller of the autonomous vehicle controls a tilt actuator to selectively tilt the chassis. Optionally, a steering actuator is coupled to the front wheels and controlled by the electronic controller to selectively steer the wheels. A sensor configured to measure orientation-dependent information may be coupled to the chassis by a gimbal configured to compensate for vehicle tilt. In some examples, the autonomous vehicle comprises an autonomous delivery robot.

An independent suspension system includes a wheel knuckle engaged with a wheel and configured to be rotated in response to a steering input; a motor assembly disposed at one end of the wheel knuckle and configured to rotate the wheel knuckle; an upper arm engaged with the motor assembly; a lower arm having a first end engaged with a vehicle body and a second end engaged with the wheel knuckle; a connection arm configured to be engaged with the upper arm; a rotation pin disposed at a connection portion between the upper arm and the connection arm to enable integral rotation of the upper arm and the connection arm; and a shock absorber disposed between the connection arm and the lower arm and engaged with the connection arm so as to be perpendicular to the connection arm.
