The invention discloses a connecting mechanism between the karting steering knuckle and the vehicle body, including the steering knuckle support unit. The side of the steering knuckle support unit is provided with the slot and the inside of which is provided with the steering knuckle. The right end of the steering knuckle is provided with the tire and the steering knuckle is connected with the tire in rotation. The rear-end of the steering knuckle is provided with the steering linkage. The upper and lower surface of the steering knuckle support unit are provided with symmetrical kingpin screw holes which are provided with kingpin screw inside. The upper surface of the steering knuckle support unit is provided with the regulating connecting rod joint and the side of the which is provided with the regulating connecting rod. The end of the regulating connecting rod away from the regulating connecting rod joint is connected to the vehicle body. The connection mechanism between the karting steering knuckle and the vehicle body is simple in structure which can make the inclination angle of the kingpin regulating rotation shaft adjustable by regulating the length of the regulating connecting rod, meanwhile, when the steering knuckle is struck by external force, the steering knuckle support unit can bear the direct stress. The steering knuckle support unit can be replaced independently without the trouble of repairing the vehicle body.

A modular robotic vehicle (MRV) having a modular chassis configured for a vehicle utilizing two-wheel steering, four-wheel steering, six-wheel steering, eight-wheel steering controlled by a semiautonomous system or an autonomous driving system, either system is associated with operating modes which may include a two-wheel steering mode, an all-wheel steering mode, a traverse steering mode, a park mode, or an omni-directional mode utilized for steering sideways, driving diagonally or move crab like. Accordingly, during semiautonomous control a driver of the modular robotic vehicle may utilize smart I/O devices including a smartphone, tablet like devices, or a control panel to select a preferred driving mode. The driver may communicate navigation instructions via smart I/O devices to control steering, speed and placement of the MRV in respect to the operating mode. Accordingly, GPS and a wireless network provides navigation instructions during an autonomous operation involving driving, parking, docking or connecting to another MRV.

The steering function-equipped hub unit includes: a turning shaft-equipped hub bearing including an inner ring, an outer ring, and rolling elements in double rows interposed between the inner ring and the outer ring, the turning shaft-equipped hub bearing having a turning shaft extending in a vertical direction; a unit support member rotatably supporting the turning shaft-equipped hub bearing (15) about a turning axis of the turning shaft; and a steering actuator configured to rotationally drive the turning shaft-equipped hub bearing about the turning axis (A). The unit support member and the steering actuator include a flange and an end portion, respectively, to be removably fixed to a knuckle which is a chassis frame component of a vehicle.

A steering system includes a first wheel and a second wheel spaced apart from the first wheel, a first tie rod, a second tie rod, and an electrical actuator. The first wheel is rotatably coupled to a first knuckle, and the first knuckle is pivotable about a first suspension post. The second wheel is rotatably coupled to a second knuckle, and the second knuckle is pivotable about a second suspension post spaced apart from the first suspension post. The first tie rod is coupled to the first knuckle and to a mechanical linkage. The second tie rod is coupled to the second knuckle and the mechanical linkage. The electrical actuator is coupled to the mechanical linkage so that movement of the electrical actuator translates the mechanical linkage axially, which adjusts the orientation of the wheels relative to the suspension posts.

A vehicle, vehicle frame, and steering system usable with the vehicle and vehicle frame. The steering system including a first and second knuckle mounted to a vehicle frame and configured to rotate with respect to the vehicle frame to turn the wheels, and a pitman arm link rotatable relative to the vehicle frame. The steering system further includes a first tie rod operably connected to the first knuckle to the pitman arm link bracket via a pitman arm and pitman connector, and a second tie rod connecting the second knuckle to the pitman arm link. A pitman connector is rotatably operatively connected to the pitman arm link, wherein the pitman arm thereby transfers pivoting or rotational motion applied via a steering input from the pitman arm to the pitman arm link, to respective knuckles via the first and second tie rods.

In a broad respect, vehicles that are capable of making a low- to zero-radius turn using the independent rotation of drive wheels and by turning the non-driving steerable structure or structures (such as wheels) with a steering input device (in some embodiments, the driving wheels also may be capable of being turned). This may be accomplished using a steering system, a speed control system and an integration device (together, a control system) that are configured to work together to provide correct steering in forward and reverse, and, in some embodiments, to reduce the speed of the outboard drive wheel of the vehicle when it enters an extreme turn under constant speed input. Different systems configured for use in such vehicles are included.
