Abstract: A spring pad for a suspension can satisfy both conflicting dynamic seating property and durability, and unification of specifications. In particular, the spring pad may include: a body portion disposed on one side of a spring to support the spring; and an insert portion embedded inside of the body portion and integrally formed with the body portion. The spring is seated on an inclined surface of the body portion, and the inclined surface may be formed in a spiral shape gradually increasing in height. A spiral curve of the inclined surface may be formed by reflecting a composite line minimizing a gap between the inclined surface and the spring.

Abstract: Disclosed herein is a manufacturing method of a spring pad interposed among a spring used in an automobile suspension system and an upper sheet and a lower sheet for supporting the spring, wherein the spring pad includes an insulator getting in contact with the spring to absorb shock and forming a body of the spring pad, and is manufactured through foam injection molding of the insulator to be lightweight.

Abstract: Disclosed herein is an over-slam bumper for a vehicle. The over-slam bumper includes: a bumper unit (100) of which an end portion protrudes toward a door to absorb shock generated between a vehicle body and the door; and a mounting unit (200) coupled with the bumper unit (100) to fix the bumper unit to the vehicle body, wherein the bumper unit (100) includes: an elastic part for absorbing shock generated when getting in contact with the door; and a coupling part (116) connected to the elastic part and coupled with the mounting unit (200). The elastic part includes a buckling part (111) for absorbing shock by buckling; a compression part (130) for absorbing shock by compression; and an elastic air compression part for absorbing shock by sealing the inside air to compress inside air.

Abstract: The present invention provides a dust cover which is provided between an engine room and the driver's seat such that, when a steering shaft provided under a steering wheel of a vehicle is installed passing through a vehicle frame, the steering shaft passes through the dust cover. The dust cover is characterized by comprising: a pair of bearings coupled to the steering shaft; a pair of bearing races provided to surround outer circumferential surfaces of the bearings; a ring-shaped fixing cap forcibly inserted into the bearing races through both sides of an opening by interference fitting, thereby fixing the bearings; and an integrally formed seal part having through-holes to which the bearing races are coupled.

Abstract: A method for manufacturing an automobile weather strip comprises: (a) weather strip manufacturing step wherein the seam material and a thermoplastic elastomer are extruded and molded; (b) pretreatment step wherein the surface of the weather strip manufactured is pretreated; (c) slip agent applying step wherein a slip agent made by mixing silicone and polyurethane is applied to the surface of the weather strip pretreated through the pretreatment step; and (d) curing step wherein the slip agent coating layer formed through the slip agent applying step is cured.

Abstract: An improved chemical cutting apparatus for cutting objects in well bores such as, for example, tubing in the bore of an oil or gas well. The apparatus is properly positioned relative to the object to be cut by means of a casing collar locator, and an igniter is fired which in turn activates a gas generator. Pressure from the gas generator axially displaces a slidable piston having suitable anchor means connected thereto. Movement of the piston causes the anchor means to move into contact with the object to be cut, thereby anchoring the apparatus relative to such object. Pressure generated in the gas generator is communicated through a passageway in the slidable piston and forces a chemical cutting agent into a chamber containing a reactant. The reaction of the chemical cutting agent and reactant increases the pressure and temperature within the chamber thereby displacing along the axis a second slidable piston.

The apparatus is properly positioned relative to the object to be cut by means of a casing collar locator and an igniter is fired, which in turn activates a gas generator. Pressure from the gas generator axially displaces a slidable piston having one or more wedges pivotally connected thereto. Movement of the piston both pivots and extends the wedge, thereby bringing the wedge into contact with the object to be cut and anchoring the apparatus relative to the object to be cut.
