A tire testing machine of the present invention includes a bottom chuck that is mounted to a bottom frame, a top chuck that is mounted to a movable beam, a ball screw that causes the movable beam to ascend or descend, and a beam fixing member that fixes the movable beam so as not to ascend. The beam fixing member includes a disk that is fixed to the ball screw and is provided with a plurality of elongated holes and air cylinders that are fixed to the vertical frame and are inserted into the elongated holes. When the pins are inserted into the elongated holes formed in the disk, the top chuck is fixed to the bottom chuck through the movable beam so as not to ascend.

A tire conveyor includes a roller portion provided at a position, in the width direction perpendicular to the conveying direction, without a conveying surface. The roller portion extends parallel to the conveying surface and is provided with a plurality of placement rollers forming a placement surface on which the tire is rotatably placed. An elevation mechanism includes a single actuator and a link mechanism connecting the roller portion or the conveyor to the actuator in a supported state and moves the placement surface of the roller portion upward and downward relative to the conveying surface by driving the actuator.

Tire conveyor for a tire testing machine

A plurality of conveyors including a center conveyor are appropriately disposed without any gap or step and any interference between driving units. The center conveyor includes a pair of left and right belt driving pulleys that are provided at the front and rear sides in the conveying direction so as to stretch loop-shaped conveyor belts therebetween and are provided at both sides in the width direction, a pair of first left and right pulleys that is connected to each other through a connection shaft disposed on rotation axes of the belt driving pulleys at both outer sides in the width direction, a pair of left and right second pulleys that is provided below the first pulleys at both outer sides in the width direction so as to stretch loop-shaped pulley belts between the first and second pulleys and includes a common rotation axis, a driving shaft that is disposed on rotation axes of the second pulleys and is connected to the pair of second left and right pulleys, and a motor that is connected to an end of the driving shaft.

Tire testing machine conveyor

A rotary drum used in a tire testing machine has a road surface base material made of an aluminum alloy and provided with a road surface onto which a tire is pushed. The road surface is coated with a thermally-sprayed steel film having higher hardness than the road surface base material, and polished. With such a configuration, a favorable test result can be obtained.

Disclosed is a tire tester () provided with: a device frame (); a slide base () provided on the device frame () so as to be able to move up and down; a large spindle () that is attached to the slide base () and can rotatably support a large-diameter tire (T); and a small spindle () that is attached to the slide base () and can rotatably support a small-diameter tire (T) that is smaller than the large-diameter tire (T). The disclosed tire tester () can push one of the tires (Tor T) against a simulated road surface (), by means of the up/down movement of the slide base (), and perform a tire test.

Tire tester

The apparatus of the invention is an injection molding apparatus of a type adapted to cool a molten metal under shearing by an extrusion screw in a substantially vertical chamber into a semi-solidified slurry and then inject the semi-solidified slurry discharged from a discharge port at the lower end of a channel into molding plates, in which a clamping device is adapted to open or close a movable plate relative to a stationary plate in the horizontal direction, and a connection member having, at the inside, a vertical first channel and a second channel extending in the horizontal direction from the lower end of the first channel and in communication with the stationary plate is connected to the discharge port at the lower end of the chamber. Since this can inject and mold light metal molding products of high quality with less pore or shrinkage without excessively enlarging the size for the height of the apparatus, casting products of high quality can be obtained at a reduced cost by injection molding.
