摘要： The invention relates to structural components of vehicles, and more particularly to the suspension of both conventional and special vehicles, such as ambulances, baby carriages and wheelchairs. The suspension comprises a quadrangular frame with a pair of arms attached thereto, where the ends of said arms are configured to be connected to the hubs of the respective wheels, and the suspension of the present invention comprises two pairs of arms—a pair of identical transverse arms and a pair of identical longitudinal arms with the ends of the longitudinal arms configured to be connected to the hubs of the respective wheels, wherein each arm is rotatably attached by its central zone to the central portion of the corresponding side of a quadrangular frame through rubber-metal joint, wherein the arms contact surfaces are cylindrical, they are adapted for mechanical coupling of arms to each other and are oriented as follows: longitudinal left and right arms have their contact surfaces oriented upwards, while transverse front and back arms have their contact surfaces oriented downwards, contact surfaces of each arm are tangent to the plane extending through the axis of rotation of the arm and are located on one side of it, while each side of the quadrangular frame rests upon the hubs of two wheels through the corresponding arm. Each transverse and longitudinal arm is made as a pair of arms spaced apart and connected by at least one connecting rod, and each such spaced arm has the form of a parallelogram. The invention is based on the objective to provide the suspension, which is more reliable due to lower level of mechanical stresses in the suspension mechanisms, which results from creation of the conditions where the function of the mechanism for changing the direction of rotation is performed by a transverse arm having a length equal to the width of the suspension.

摘要： The present invention relates to sports equipment, namely, to roller skates design enabling an athlete to achieve high speed of movement with better comfort and improved motion control, in particular, in case of movement on a lower quality road surfaces. Roller skates consist of two skates—right and left ones, each comprising a spatial rectangular frame with its upper surface adapted to be attached to a frame of the corresponding shoe, either left or right one, and its lower side having two pairs of rollers pivotally attached thereto such that the rollers may rotate being in contact with the roadway and the rollers' axes are parallel to the frame plane, and according to the invention each pair of front and rear rollers of each skate is pivotally attached to the corresponding Z-shaped wheel arm, either front or rear one, which has its central section pivotally attached to the corresponding smaller side of the spatial rectangular frame, and the distance between the axes of the inner rollers of a skate is greater than the distance between the axes of the external rollers. The present invention is aimed to provide such roller skates, which would be more reliable and safe due to increased stability of the skates during movement, also in case of lower quality road surface and during cornering. This objective is achieved by way of creating conditions for uniform distribution of the load arising from the weight of the athlete during movement among all four rollers of each skate, even when moving on a lower quality road surface.

摘要： The invention relates to suspension design. The present vehicle suspension comprises a quadrangular frame. Each corner portion of the frame has a wheel block kinematically attached thereto so as to form two pairs of wheels—a front pair and a rear pair. On each side of the frame, longitudinal and transverse coupling cables are fastened for movement therealong inside housings. Each wheel block consists of a body that is simultaneously connected to two coupling cables. Movably mounted on the body are parallel horizontal arms, the first of which is fastened to the body by its middle portion. A knuckle with the hub of a wheel is attached to an end of the first arm and to another end of the second arm, and two coupling cable dampers are attached to the other end of the first arm. The housings of the cables are attached to the body of the corresponding wheel block. The free end of each cable is enclosed in a damper. Mounted on the cable end portions that freely project from the housings in front of a damper are spring stabilizers of the position of the wheel of the wheel block. Each coupling cable is provided with a linear actuator. The result is an increase in the stability and smoothness of movement of a vehicle.

摘要： The present inventions relate to structural components of vehicles, and more particularly to suspension variants of both usual cars and special higher comfort vehicles, such as ambulances, baby carriages and wheelchairs, and also the suspension with catamaran floats. The proposed suspension, which may be used in ground and water vehicles, is configured to enable automatic road clearance and body tilt adjustment depending on the condition of the roadway, sea roughness, the speed of the vehicle and the maneuver being performed. The first variant of suspension comprises a frame, four identical arms intended to be connected with the hubs of the respective motion parts, and torsion bars attached to the frame through the bearing assemblies and connected to the arms of the corresponding motion parts, where at least two torsion bars may freely rotate with a twisting angle under the load of 1-5° and form, respectively, front and rear axis, the torsion bars are installed in parallel and their centers are kinematically connected to a connecting rod mounted in such a manner to allow synchronous axial rotation of the torsion bars, the arms of one axis are attached to the ends of the corresponding torsion bars and are installed in parallel, while the arms of each side of the suspension, i.e. right or left, are oriented in opposite directions, wherein the suspension according to the invention comprises at least four torsion bars disposed in pairs in a horizontal plane, and, additionally, the main and additional movable connection arms and linear actuators that are mounted in such a manner to allow synchronous change of their lengths, while the center of each torsion bar is connected to the connecting rod via an additional connection arm, which can freely rotate on the torsion bar, all additional connection arms are parallel, identically oriented and connected with each other by appropriate rods, and the arms of the corresponding motion parts of one axis are attached to the ends of the corresponding torsion bars, installed in parallel and oriented in opposite directions towards each other. The second variant of suspension comprises a horizontally disposed frame, a steering mechanism, four identical wheel arms, each intended to be connected at one end to the hub of the corresponding wheel, and to be connected at the other end, through a bearing assembly attached to the frame, to a coupling device installed with the possibility of its free rotation, and the coupling devices form, respectively, front and rear suspension axles, the axes of the coupling devices of both axles are installed in parallel and the arms of the wheels of one axle are installed in parallel, wherein according to the invention, each coupling device of the suspension is made in the form of an elastic coupling or a rubber-strand torsion bar, each suspension axle is provided with a mechanism for changing the direction of rotation, which is connected via appropriate coupling devices to wheel arms, the housing of said mechanism is attached to the frame of the vehicle, and the axles are interconnected by a longitudinal linkage rod, the wheel arms are attached to the frame thought the rubberized bearing assemblies and are placed in the horizontal plane, with the front left and right arms oriented forward, in the direction of movement, the rear right and left arms are oriented rearward, or vice versa, the front left and right arms are oriented backward, against the direction of movement, and the rear right and left arms are oriented forward, in the direction of movement, or the front left and right arms and rear right and left arms are oriented rearward and are mounted in such a manner to allow placement of the right and left wheels of one axle on one axis, linkage arm is installed on each axis of the wheel arms with the angle 90°±30° between said linkage arm and the arm of the corresponding wheel, linkage arms are parallel and oriented identically—either upward or downward—depending on the intended purpose of the suspension and are interconnected by a longitudinal rod for synchronous rotation of the axes of the wheel arms. The invention is based on the objective to provide a suspension featuring increased off-road capability, smoothness and stability during the movement, also in off-road conditions. The objective is attained by creating conditions for automatic adjustment of clearance and body tilt, depending on the condition of the roadway, sea roughness, vehicle speed and maneuver performed by using longer wheel arms without changing the length of the wheelbase and the possibility to choose optimal mutual orientation of said arms depending on the purpose of the suspension.
