A structurally supported tire includes a ground contacting annular tread portion, an annular shear band and at least one spoke disk connected to the shear band, wherein the spoke disk has at least two spokes, wherein each spoke extends between an outer ring and an inner ring, wherein one of the spokes extends from the outer ring to the inner ring in a curved manner. The second spoke extends from the outer ring to the inner ring in a straight manner.

A reduced height combination ramp and load leveler includes at least two lengthwise support members, a plurality of cross members and plurality of cross treads. A retention tube is secured to each end of the at least two lengthwise support members. The at least two lengthwise support members and the plurality of cross members are preferably fabricated from an aluminum alloy having a tensile strength of at least 50,000 to reduce a height of the combination ramp and load leveler. Two stake receivers allow a single ramp to be used as a load leveler. Each stake receiver is sized to removably receive an adjustable stake. A ramp stand includes a support base and an adjustable tube receiver that is vertically positionable relative to the support base. The adjustable tube receiver retains the retention tubes.

The invention discloses a tire DOT information identification method based on end-to-end deep learning, and the method comprises the following steps: carrying out the feature extraction of a tire image, obtaining first feature maps outputted in N stages, and carrying out the feature fusion of the first feature maps outputted in N stages, and obtaining a second feature map; performing DOT information rough positioning on the fused second feature map to detect whether three characters of DOT and position information thereof exist or not, and obtaining an area map; generating a mask image from the region image, multiplying the mask image by the second feature image, performing DOT information fine positioning on a third feature image obtained by multiplying to obtain DOT information text probability and position information, and positioning to candidate text blocks with angles; performing tire bending direction detection on the first feature map output in the last stage to obtain character direction information of the tire tread; performing affine transformation on the candidate text blocks and the character direction information of the tire tread, and converting the candidate text blocks and the character direction information into horizontal text blocks in the upward direction; and inputting the horizontal text blocks into a text recognition network based on deep learning to carry out DOT character recognition to obtain final recognition information.

The invention relate to a novel light bicycle tire which comprises a left tire bead portion, a right tire bead portion, side wall portions and a tire tread portion. The side wall portions extend from the tire bead portions to the radial outer side of the tire, and the tire tread portion is in bridge connection with the two side wall portions. The tire tread portion comprises a crown in contact with the ground and tire shoulders connected with the side wall portions. The novel light bicycle tire further comprises a cord fabric layer folded back to wrap the tire bead portions for a circle, and the edge of the cord fabric layer is folded upwards around a bead core to be anchored in the two tire shoulders in a wrapping mode. The tire tread portion comprises a reinforced cord fabric layer and a tire tread layer which are sequentially on the outer side of the cord fabric layer and annularly arranged in the circumferential direction of the tire, and the reinforced cord fabric layer and the cord fabric layer are arranged on the two tire shoulders in an overlapped mode. The cord fabric layer is folded to wrap the tire bead portions for a circle, and the reinforced cord fabric layer arranged on the outer side of the cord fabric layer is used in combination, so that the tire tread portion is divided into two layers, and the tire side portion is divided into two layers; under the condition of reducing the weight of the tire, the safety and durability of the tire are also guaranteed, weight reduction of the bicycle tire is achieved, and the requirement for riding comfort is met.

The invention discloses a non-falling wheel-type wheelset multi-stage out-of-roundness measurement system comprising an image acquisition device for acquiring a contour curve of a wheel tread, a top runner mechanism for lifting the wheel and driving the wheel to rotate, and a mobile platform for carrying and transferring the image acquisition device and the top runner mechanism, wherein the imageacquisition device comprises a camera and a linear light source; the top runner mechanism comprises a swing arm for lifting the wheel and a runner for driving the wheel to rotate; the mobile platformcomprises a vehicle body, a walking wheel is arranged below the vehicle body, and the vehicle body contains a controller; and a processing computer for analyzing the images acquired by the image acquisition device and outputting a calculation result of out-of-roundness is provided. The wheelset out-of-roundness is measured on-line to avoid the heavy work of disassembling the wheelset. The compactdesign allows free access to the maintenance trench. The mobile measuring mechanism can cover all wheelsets in the parking lot.

The invention discloses a twist drill rod which comprises a twist rod body. A connecting column is arranged at one end of the twist rod body, a connecting hole is formed in the other end of the twistrod body, the connecting column is provided with an external thread, the connecting hole is internally provided with an internal thread matched with the external thread on the connecting column, a torque transmission assembly is arranged in the connecting hole, the torque transmission assembly comprises an inner screw and a connecting sleeve pipe, and the connecting sleeve pipe sleeves the inner screw and is connected with the inner screw through the treads. A first plane clamping tooth is arranged at the end of the connecting sleeve pipe, a blind hole corresponding to the connecting sleeve pipe is arranged on the middle part of the connecting column, and a second plane clamping tooth corresponding to the first plane clamping tooth is arranged at the bottom of the blind hole. When the drill rod is driven, torque force between the connecting hole and the connecting column can be shared between the inner screw and the connecting sleeve pipe as well as between the first plane clamping tooth and the second plane clamping tooth, and the damage of the torque force to the threads between the connecting hole and the connecting column can be reduced.

The invention relates to a tire having a radial casing framework consisting of at least one layer of metal reinforcement elements. Said tire includes an upper framework which is itself radially covered with a tread that is joined to two beads by means of two flanks. The reinforcement elements of the casing framework layer consists of at least one wire-like element and at least one sheath that coats said wire-like element. Said sheath includes at least one thermoplastic polymer composition layer, and the rubber mixture thickness between the inner surface of the cavity of the tire and the point of a metal reinforcement element of the casing framework that is nearest said inner surface of the cavity is higher than 3.8 mm.

In a pneumatic tire, center blocks in a center region of a tread portion form a pair sandwiching an inclined groove that extends inclined with respect to a circumferential direction. Each of the center blocks extends across an equator and includes a notch formed of first and second walls that are connected in a V-shape in a tread road contact surface. The first wall extends within + / −20° with respect to the circumferential direction, and the second wall extends within + / −10° with respect to a lateral direction. Each of shoulder blocks provided in a center region of the tread portion includes a third wall opposed to the notch and at an angle within + / −5° with respect to a straight line connecting an end point of the first wall, located adjacent to the shoulder block and an end point of the second wall, located adjacent to the shoulder block.
