A suspension unit has a piston assembly connected to an adjuster. The piston assembly has three or more concentric cylindrical bodies including: an outer tube; an inner tube, and a dampener rod. The dampener rod is inside and concentric to the inner tube. The outer tube is rigidly connected to the dampener rod. The inner tube is telescopically mounted to the outer tube. The inner tube is inside and concentric to the outer tube. The adjuster has an adjuster compression entry port. The axle clamp rebound port connects to an adjuster block rebound entry port. The adjuster block has a high-speed compression cavity formed on an end of the adjuster block.

The present invention relates to a two-wheel electric vehicle, comprising: a frame (1); a housing (3) connected to the frame (1); one front wheel (2) and one rear wheel (6); and a gyroscope device (5), the gyroscope device (5) comprises a flywheel (13); and a control system (10), the control system (10) controlling a precession angular speed of the flywheel (13) within a period during which the two-wheel electric vehicle is started but does not run, a period during which the two-wheel electric vehicle runs normally or a period during which the two-wheel electric vehicle steers, to keep balance of a vehicle body. The two-wheel electric vehicles solves the technical problem existing in the prior art of poor stability of the two-wheel electric vehicle.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

A power transmission assembly for tandem axles of a vehicle, the assembly including an input axle, a first drive axle, a second drive axle, a plurality of engagement/disengagement devices, a locking device, and a differential unit. The differential unit being set for power distribution between the drive axles of the vehicle, from which, in cooperation with the engagement/disengagement devices and the locking device, enables configurations of the drive axles in which the first and the second drive axles are driven, one of the drive axles is driven and the other drive axle is not driven, or all the drive axles are not driven.

A seating arrangement for a vehicle having a cabin space is provided. The seating arrangement includes a vehicle, at least one front seat within the vehicle, and at least one rear seat arranged behind the at least one front seat of the vehicle. The at least one front seat is rigidly fixed to and suspended from a portion of the vehicle, thereby providing a free space underneath the at least one front seat, such that an occupant of the vehicle seated in the at least one rear seat is able to position at least a lower portion of one or both legs thereof in the free space underneath the at least one front seat. A flexible covering, such as bristles may be attached to the periphery of the vehicle floor opening, so that a driver's foot can pass from inside the vehicle cabin, to the ground outside the vehicle.

A system and method of stabilizing a two-wheeled vehicle are disclosed. In accordance with one aspect, a self-stabilizing two-wheeled vehicle having an articulated frame may generally comprise: a front wheel and a rear wheel substantially aligned along a longitudinal axis; a base frame portion coupled to the front wheel and to the rear wheel via respective front and rear suspension components; an operator frame portion to support an operator of the vehicle; a hinge assembly operably coupling the base frame portion and the operator frame portion; and a control unit to drive the hinge assembly causing the operator frame portion to rotate about a hinge axis as a function of inertial data and speed data.
