Abstract:
The present invention relates to an electrical clamping apparatus for fixing the position of a vehicle component and, to a clamping apparatus for fixing the position of a component in a movable production line comprising: a drive motor; a warm shaft which rotates by the drive motor; a warm wheel which rotates while being engaged with the warm shaft; a rotating shaft which rotates while being engaged with the warm wheel; a pressure member for fixing the position of a component which is under production in a production line since the pressure member is moved by being combined to the end of the rotating shaft and interlocked with the rotating shaft; and a control part for rotating the drive motor until the pressure member reaches a fixing position where the pressure member fixes the position of the component in the production line from an opening location where a moving path of the component is opened by pressurizing the component. The position of a vehicle component such as a vehicle chassis, etc. which moves along a production line by using the drive motor is fixed at a position of processes such as welding, etc., wherein the drive motor occupies small space, and has a rapid response speed in comparison with a pneumatic clamping apparatus. Therefore, an electrical clamping apparatus for fixing a position is capable of preventing safety accident while efficiently, correctly, and rapidly implementing a production process of a vehicle.

PURPOSE: A method for controlling an electric oil pump of an ISG(Idle Stop and Go) vehicle is provided to improve the durability and fuel efficiency of an ISG vehicle by actively controlling the driving speed of an electric oil pump according to oil temperature. CONSTITUTION: A method for controlling an electric oil pump of an ISG vehicle is as follows. When a vehicle with an ISG function is traveling, whether an idle stop function is activated is determined(S101,S102). If the idle stop function is activated, an oil pump is driven at a certain speed and current consumption is detected(S103,S104). A map set according to the speed of the electric oil pump and the current consumption is applied to detect the oil temperature(S105). The driving speed of the electric oil pump is variably controlled according to the oil temperature(S107). The oil temperature is applied to determine the speed of the electric oil pump and line pressure and the operation of the electric oil pump is controlled to maintain the line pressure(S111,S112).
Abstract:
An apparatus for controlling cooling of a piston for an internal combustion engine is provided to remarkably reduce the capacity of an oil pump and increase the fuel efficiency of an engine by detecting the behavior and temperature of the piston using electromagnetic induction, and variably controlling the discharge rate of oil through a cooling jet depending on the data on the behavior and temperature of the piston. An apparatus for controlling cooling of a piston for an internal combustion engine includes a temperature sensor(12), a first induction coil(13), a second induction coil(16), a rectifier circuit(20), a smoothing circuit(30), a comparator(40), and a control unit(50). The temperature sensor is mounted on the upper portion of the piston(11) to measure the temperature of the piston. The first induction coil is mounted on the lower portion of the piston, and is electrically connected to the temperature sensor. The second induction coil is provided at a predetermined position under a cylinder(10) having a water jacket(14), with first and second coils wound around the second induction coil by a preset number of turns. The rectifier circuit rectifiers an electromagnetic waveform induced from the second induction coil by the reciprocating motion of the piston, thus converting it into DC voltage. The smoothing circuit averages the rectified waveform to convert it into a signal of a square wave. The comparator compares the signal of square wave with a preset reference voltage, thus transmitting the compared result to the control unit. The control unit analyzes the signal transmitted from the comparator to detect the temperature and position of the piston, and controls the operation of an oil pump(90), thus controlling the discharge rate and discharge time of oil through a cooling jet.
