A die casting apparatus according to an aspect of the present disclosure includes a sleeveto which molten metal is supplied, and diesandconfigured to form a cavity C, in which the molten metal supplied to the sleeveis injected into the cavity C through a runner R linking the sleevewith the cavity C. A plurality of protrusionsare provided in the runner R, the plurality of protrusionsextending in a direction in which the molten metal flows and being arranged in a comb-teeth arrangement in a width direction of the runner R.

Die casting apparatus

A vehicle drive includes a speed change mechanism connected to a rotary electric machine; an output member connected to the speed change mechanism and wheels; an engagement device changes a state of engagement between an input member connected to an engine and the speed change mechanism; a hydraulic pump driven by the engine or the rotary electric machine; a first pressure control device that controls pressure supplied from the pump and supplies the pressure to the speed change mechanism; a second, separate hydraulic pressure control device that controls the pressure supplied from the pump and supplies the pressure to the engagement device; and a case that houses the rotary electric machine, speed change mechanism, engagement device, and pump. At least the engagement device is housed in a space formed by the case, and the second hydraulic pressure control device is provided at a part of the case forming the space.

Vehicle drive device

A power transmission system () for a hybrid vehicle, the power transmission system () includes a transmission (TM,), a clutch (), a motor (MG), an engine (), a first oil pump (), a second oil pump (), a first hydraulic circuit in which the first oil pump () is provided, and a second hydraulic circuit in which the second oil pump () is provided. The motor (MG) is connected to a driving wheel () through the transmission (TM,). The engine () is connected to the motor (MG) through the clutch (). The first oil pump () supplies oil to the transmission (). The second oil pump () supplies oil to the motor (MG) and the clutch (). The second hydraulic circuit is independent from the first hydraulic circuit. Selected drawing.

Power transmission system for hybrid vehicle

A fluid transmission device for a vehicle includes a cover and a positioning member. The cover is configured to be driven rotatably about the axis of the fluid transmission device integrally with a drive plate. The drive plate includes a positioning hole that positions the drive plate and the cover. The positioning member is a columnar member. The positioning member is provided on the surface side of the cover, which is opposed to the drive plate, at a radially outer position of the cover. The positioning member protrudes to a drive-plate side in a state where the positioning member is arranged in the positioning hole. The positioning member protrudes from the drive plate obliquely with respect to the axis direction of the fluid transmission device. A radially outermost position of the positioning member is located on the radially inner side relative to a radially outermost position of the cover.

Fluid transmission device for vehicle

Even when a motor fails in an EV travel mode in which a clutch is disengaged, an amount of hydraulic oil that is supplied to the clutch can be secured by reducing a transmission leaked amount. Accordingly, the clutch can be engaged, and an oil pump can be driven by power of an engine. Thus, an evacuation travel by the engine is allowed when the motor fails in the EV travel mode.

Vehicle configured to secure oil during motor failure

A controller for vehicle, the vehicle including plural engagement elements for performing engagement operation by hydraulic pressure, the plural engagement elements having a common engagement element being an engagement element common to plural transmission gear stages, the common engagement element being an engagement element that is brought into an engaged state for establishing a transmission gear stage immediately before start of economic running and a transmission gear stage immediately after cancellation of the economic running, the controller includes at least one electronic control unit configured to stop an engine in the case where a specified economic running start condition is established and switch the plural engagement elements between the engaged states and disengaged states such that the common engagement element is switched from the engaged state to the disengaged state after another engagement element that is brought into the engaged state together with the common engagement element.

Controller for vehicle

Provided is a vehicle control apparatus. To start an engine by a motor-generator under the state that a vehicle is stopped, the vehicle control apparatus synchronizes a rotation of the engine with a rotation of the motor-generator at a synchronous rotational speed lower than a target rotational speed to start the engine, and increases a rotational speed of the engine by the motor-generator from the synchronous rotational to the target rotational speed, and starts the engine at the target rotational speed.

Vehicle control apparatus

A control device of a vehicle includes an engine, an electric motor, and a first clutch connecting/disconnecting a power transmission path between the engine and the electric motor, and a second clutch configured to achieve a mechanically directly-coupled state of a power transmission path between the engine/the electric motor and drive wheels, the control device of a vehicle increasing a torque of the electric motor and causing the second clutch to slip-engage when the engine is started by controlling the first clutch toward engagement during motor running using only the electric motor as a drive force source for running with the first clutch released and the second clutch engaged, when the torque of the electric motor increased at the start of the engine relative to the torque of the electric motor during the motor running is larger, a slip amount of the second clutch being made larger as compared to when the torque is smaller.

Vehicle control device

To provide a vehicle control apparatus which can suppress a shock in a clutch from being generated at a time of starting an engine by a motor in a vehicle having the clutch provided therein between the engine and the motor, thereby improving a drivability of the vehicle. Provided is a vehicle control apparatus, comprising: an engine, a motor generator connected to vehicle wheels of a vehicle, and a clutch that switches a transmission state between a disengaging state and an engaging state, in which the vehicle control apparatus switches the clutch in the engaging state to start the engine by the motor generator. When the engine is started by the motor generator, the vehicle control apparatus constantly keeps the compensation torque of the motor generator smaller than the clutch torque of the clutch.

A vehicle control device includes: an engine and a first motor generator from both of which a driving force for traveling is output to drive wheels; and an electricity storage device that storages electric power for driving the first motor generator. When a vehicle weight is in a reference state at a time of deceleration braking, the first motor generator is mainly caused, out of the first motor generator and the engine, to generate a braking force, and when the vehicle weight is greater than that in the reference state, the engine is mainly caused, out of the first motor generator and the engine, to generate the braking force. Thus, a sufficient braking force can be obtained while an input limit of the electricity storage device is prevented from being reached.
