Techniques regarding a vehicle suspension assembly are provided herein. For example, one or more embodiments described herein can regard an apparatus that can comprise a locking plate that can be located between a first spring and a second spring in a first direction. Also, the locking plate can comprise a locking pin. Moreover, the apparatus can comprise a locking sleeve that can surround the first spring and the locking plate. The locking sleeve can comprise a first channel that traverses the locking sleeve in the first direction. The locking sleeve can further comprise a second channel that is connected to the first channel and traverses the locking sleeve in a second direction.

A stabilizer includes a stabilizer bar and a rubber bush. The stabilizer bar includes a bar body made of a steel and a coating film covering the bar body. The coating film is formed on the surface of the bar body by using a resin having a water contact angle of more than 65°. By performing surface treatment for reducing the contact angle of the coating film present on an attachment part, the contact angle of the attachment part is changed to 65° or less. A pre-cured liquid adhesive agent is applied to an inner surface (adhesion surface) of the rubber bush. After a region including the attachment part of the stabilizer bar is heated, the rubber bush is overlaid on the attachment part. The adhesive agent is cured in a state where the rubber bush is pressed.

An autonomous mobile robot (AMR) for a plurality of outdoor applications is provided. The AMR includes a base frame configured to obtain the configurable base frame based on one or more parameters; a first drive wheel sub assembly, and a second drive wheel assembly is additionally re-oriented oppositely to the first drive wheel assembly to form a drive wheel assembly; a plurality of suspension units is configured by the one or more side plates of the configurable base frame and a plurality of gearboxes; and the plurality of gearboxes is configured to as a plurality of configurable gearboxes for obtaining different drive power of the drive wheel assembly by at least changing one of one or more dimensions of a plurality of gearbox plates, one or more ratio of a wheel shaft gear and a motor gear shaft, and one or more specification associated with a plurality of drive motors.
