An apparatus for power transmission of a vehicle, including a motor having a motor spline unit extending therefrom, and configured to generate power, a rotating body configured to receive the power and rotate, and a coupler having a toothed structure including grooves and having an exterior to be coupled to the motor spline unit and an interior to be coupled to the rotating body, wherein a width of the grooves formed at one end of the interior is larger than a width of the grooves formed at an opposite end of the interior, a width of the grooves formed at one end of the exterior is smaller than a width of the grooves formed at an opposite end of the exterior, and the coupler is coupled in a tension coupling with the rotating body and the motor.

Apparatus for power transmission of vehicle

This invention relates to a lyocell material for a tobacco filter and a method of manufacturing the same, and more particularly to a lyocell fiber having a modified cross-section for a tobacco filter, wherein the cross-sectional shape of a monofilament contained in a lyocell fiber is controlled to increase the external surface area of the fiber, after which then crimps are formed, thereby exhibiting properties equal or superior to those of conventional lyocell materials, even when used in a small amount.

Modified cross-section lyocell material for tobacco filter, and preparation method therefor

A master cylinder of a brake for a vehicle may include: a housing having a port through which oil is transferred; a motor connected to the housing so as to supply rotary power; a screw rotatably installed in the motor, and rotated by the rotary power received from the motor; a moving piston engaged with the outside of the screw, and moved in the longitudinal direction of the housing by the rotation of the screw; and a fixed piston fixed to the inside of the housing, and having the moving piston positioned on the outside thereof.

Master cylinder of brake for vehicle

Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.

Lyocell material for cigarette filter and method for preparing same

This invention relates to a method of manufacturing a lyocell material for a cigarette filter, including (S1) spinning a lyocell spinning dope composed of 8 to 13 wt % of a cellulose pulp and 87 to 92 wt % of an N-methylmorpholine-N-oxide (NMMO) aqueous solution; (S2) coagulating the lyocell spinning dope spun in (S1), thus obtaining a lyocell multifilament; (S3) water-washing the lyocell multifilament obtained in (S2); (S4) oiling the lyocell multifilament water-washed in (S3); and (S5) applying steam and pressure to the lyocell multifilament obtained in (S4), thus obtaining a crimped tow having 30 to 40 crimps per inch.

A machine for folding a side curtain airbag which has a simpler machine configuration and is more efficient than a fully automatic machine and that can fold a large-capacity side curtain airbag cushion of approximately 4.0 m in length to sufficiently secure quality stability, and a process for folding a side curtain airbag by using the same, are provided.

Folding machine for side curtain airbag and process for folding side curtain airbag using the same

A polyester sewing thread usable for a fabric for an airbag and a cushion for an airbag is provided. The polyester sewing thread is obtained by doubling and twisting a specific polyester yarn including a plurality of polyester filaments, and bonding the polyester yarn in the manner of in-bonding, out-bonding, or in-and-out bonding. A method for producing the thread is also disclosed.

Polyester sewing thread for airbag and preparation method thereof

The present invention relates to an airbag including an inflating part having gas inflatability, a non-inflating part supporting the inflating part, a combined part constituting a boundary between the inflating part and the non-inflating part, and an ultrasonic fusion bonded part located between the combined part and the end part of an inflator from which a gas at a high pressure spurts when a car crashes, and a preparation method thereof.

Airbag and a preparation method thereof

A load supporting structure of an electric booster type brake apparatus, includes: a housing including a rear housing member and a front housing member so as to define a receiving space therein; a ball screw shaft rotatably installed in the receiving space of the housing; a rotor installed at one side of the ball screw shaft so as to transmit torque; a first bearing installed between the rear housing member and one side of the rotor and configured to support a radial direction load due to a hydraulic reaction force; and a second bearing installed between the front housing member and the other side of the rotor and configured to support an axial direction load due to a hydraulic reaction force. Therefore, the number of components and the thickness of the housing are reduced, and therefore weight reduction of the electric booster type brake apparatus may be implemented.

Load supporting structure of electric booster type brake apparatus

The present disclosure provides an in-wheel drive apparatus. The apparatus includes a motor housing open at one side thereof, a motor unit mounted within the motor housing, and a rear cover coupled at one side thereof to the motor housing to close the open side of the motor housing and coupled at the other side thereof to a trailing arm. The rear cover includes a planar section constituting an outer peripheral surface of the rear cover; and a cover recess connected to an inner peripheral surface of the planar section to be integrally formed with the planar section and depressed from the planar section towards the rotor to form a recess to which the trailing arm is coupled.

In-wheel drive apparatus

An airbag is prepared by: (a) providing a woven fabric by weaving polyamide filament of the same density in the warp and weft directions; (b) forming a low air permeability fabric by heat-setting the above woven fabric at a temperature less than 180.degree. C.; (c) forming a high air permeability fabric by heat-setting the above woven fabric at 190.degree. C.-220.degree. C.; and (d) sewing the high and low air permeability fabric together after locating the low air permeability fabric as the front panel, and the high air permeability fabric as the back panel.

Airbags and process of preparation

An uncoated fabric for producing airbags, said fabric woven of synthetic monofilaments and having a monofilament denier in the weft which is less than that of the warp.
