Abstract: A wheel for vehicles may include a rim coupled to a tire, and a spoke-shaped disc including a spoke and a vent hole, the spoke-shaped disc being coupled to a side surface of the rim to support the rim, in which a coupling zone between the spoke of the spoke-shaped disc and the rim and a coupling zone between a portion of the spoke-shaped disc formed with the vent hole and the rim have a height difference in a wheel axis direction, to allow the spoke-shaped disc to support the rim at an interior and an exterior of the rim.

Abstract: A touch display device includes a touch sensor, a visual accelerator, and a display. The touch sensor senses a touch. The visual accelerator visualizes the touch. The display displays information corresponding to the visualized touch. When the touch is outside a visual acceleration area, the visual accelerator does not process the touch. When the touch is in the visual acceleration area, the visual accelerator visualizes the touch on the display.

Abstract: A trailing arm bush may include a cylindrical outer pipe, an inner pipe inserted to a central portion of the outer pipe at an interval, a first bush rubber unit, a second bush rubber unit and a third bush rubber unit that connect between an inner peripheral surface of the outer pipe and an outer peripheral surface of the inner pipe, respectively, a hollow void part formed between the inner peripheral surface of the outer pipe and the outer peripheral surface of the inner pipe, and a stopper attached to the inner peripheral surface of the outer pipe and disposed among the first bush rubber unit, the second bush rubber unit and the third bush rubber unit.

Abstract: A coupled torsion beam axle for vehicles may include a torsion beam disposed in a vehicle width direction and trailing arms disposed at both ends of the torsion beam in a length direction of a vehicle body, wherein the torsion beam has an opened cross section formed in a reverse “U” shape by press-forming one sheet member machined so that lengths of right and left sides are different from each other on the basis of a center, and cross section widths which are different from each other along vehicle width directions of both sides on the basis of the center between the trailing arms of both sides, and front and rear surfaces formed in a wave shape along the vehicle width directions of both sides on the basis of the center.

Abstract: The object of this invention is to provide an automatic container locking apparatus for trailers. This locking apparatus is automatically operable in response to the weight of a container to lock or unlock the container on the deck of a trailer. This locking apparatus has a housing (10) vertically set in the deck (1), with a spring-biased actuator (20) movably set within the housing (10). A spring-biased locking bolt (30) having a top head (31) is movably set within the actuator (20). This locking bolt (30) has a stopper (32) and a curved guide slit (41), thus being selectively moved together with the actuator (20) while being rotated. A support shaft (50) holds the vertical position of the locking bolt (30) within the housing (10). An actuation pin (51) of the shaft (50) engages with the curved guide slit (41), thus allowing the locking bolt (30) to be rotatable when the locking bolt is vertically moved together with the actuator (20).
