A link-type front suspension device for a motorcycle to improve an engine cooling efficiency without restricting a flow of engine cooling air during its running operation. The suspension device includes a split push rod having a pair of right and left rod members, the lower ends of which are rotatably attached to the front wheel supporting arms, and the upper ends of which are rotatably attached to the cushion arms. In addition, the rod members are arranged to the rear of each of the pair of right and left front forks in such a way that they overlap the forks as seen from a front elevational view. Accordingly, there is no element above the front fender and between the right and left front forks, and a appropriate wide space is formed therebetween, the space acting as an engine cooling air feeding inlet during the running operation.

The invention relates to a method for drawing shaped parabola revolving body, belonging to the technical field of the plastic forming of material processing engineering. The method comprises the following steps: (1) a set of mould is designed according to the final shape of revolving body parts; (2) the first drawing: when being drawn, a movable soft punch cushion block is arranged on a mould punch; the inner shape of the movable soft punch cushion block is similar to the shape of the punch; a movable rigidity limit cushion block is arranged below a blank holder with a belt drawbead; (3) the annealing heat treatment, the annealing heat treatment is carried out on the parts after the first drawing is carried out on the parts; (4) the second drawing, the same set of module is used; when in drawing, the movable soft punch cushion block and the movable rigidity limit cushion block are removed. In the invention, the movable soft punch cushion block is added on a drawing mould rigidity punch for enlarging the plastic forming of the materials in the first drawing; only one set of drawing module is used on an ordinary hydraulic press, therefore, the parahola revolving body parts which are usually formed with 3-4 sets of moulds by the common drawing processing are successfully formed by twice drawing.

The invention relates to an asphalt pavement structure suitable for the Tibet plateau area and a construction method thereof. The asphalt pavement structure suitable for the Tibet plateau area sequentially comprises a cushion layer, a semi-rigid base layer, a penetrable layer, an SBR emulsified asphalt lower sealing layer, a lower surface layer, a bonding layer and an upper surface layer from bottom to top. The construction method of the asphalt pavement structure suitable for the Tibet plateau area comprises the following steps of (1) tamping and leveling a roadbed, (2) laying the cushion layer on the roadbed, (3) laying a cement stabilized sand gravel layer on the cushion layer, (4) flatly laying a low-shrinkage super-early-strength cement stabilized macadam layer, (5) laying the penetrable layer, (6) laying the SBR emulsified asphalt lower sealing layer, (7) laying the lower surface layer, (8) laying the bonding layer, and (9) laying the upper surface layer.

The invention relates to a ceramic blank forming die favorable for solving problem of difficult demoulding, belongs to the field of ceramic formation, and aims to solve the problem that the prior ceramic forming die is difficult to demould during use. The die comprises a die cushion, a die cavity, and an upper punch, which are mutually packaged in turn and used together; and the die adopts the key point that the die cavity consists of two valve groove shaped objects, the structure of the die also comprises six supporting arm shaped objects, wherein four supporting arm shaped objects of the six supporting arm shaped objects are mutually hinged from beginning to end to form a closed chain structure, a pair of opposite vertex angles of the chain structure is hinged with one end of each of the rest two supporting arm shaped objects respectively, the rest other end of each of the rest two supporting arm shaped objects is connected with the two valve groove shaped objects respectively, the arm shaped objects are made of magnetic conducting materials, and the surface of at least one arm shaped object close to the groove shaped objects at structural position is wound with a magnet exciting coil. The die can conveniently control opening, closing, loosening, and fastening by a power supply switch.

A nipple cushion formed as part of an insert for a breast-receiving funnel-shaped membrane of a breast pump. The nipple cushion may include an adhesive to form a temporary bond to any type of a breast pump cushion. Such a nipple cushion of the present invention absorbs any friction created by the movement between the breast pump and the user's breast, with the aid of the material that constitutes the nipple cushion.

The invention relates to a composite seat energy absorption structure for vehicles. The composite seat energy absorption structure comprises a seat back, a seat cushion and a buffer and energy absorption structure. The bottom ends of two sides of the seat back are mounted to the rear ends on two sides of the seat cushion respectively through connecting plates, a front mounting support and a rear mounting support are arranged on the lower sides of each connecting plate, and each front mounting support is hinged to the seat cushion. The composite seat energy absorption structure is characterized in that the buffer and energy absorption structure comprises C-shaped buffer plate structures and buffer and energy absorption material layers, wherein each C-shaped buffer plate structure is mounted between each rear mounting support and the seat cushion, and the buffer and energy absorption material layers are arranged on the back of the seat back and the bottom of the seat cushion. Each C-shaped buffer plate structure comprises a C-shaped buffer plate and a limiting plate, one endpoint of each C-shaped buffer plate is hinged to the the rear mounting support of the corresponding connecting plate while the other endpoint is hinged to the seat cushion, a positioning hole and a limiting slot are formed in each limiting plate, one endpoint of each C-shaped buffer plate is hinged to the positioning hole of the corresponding limiting pate while the other endpoint is moveably mounted in the corresponding limiting slot, the positioning holes are round holes, the limiting slots are oblong holes, and the circle center of each positioning hole is located on the center line of the corresponding limiting slot.
