A motor assembly includes a motor, a speed reducer attached to one axial end of the motor, and an oil feeder between the motor and the speed reducer. The oil feeder is made of a material having elasticity and capable of storing a lubricating substance. The oil feeder includes a first lubrication portion that lubricates a gear of the speed reducer and a second lubrication portion that lubricates a bearing of the speed reducer.

Methods and systems are provided for integrating a gearbox into an electric motor. In one example, a system may include enclosing a gearbox containing a planetary gear set and a differential within an envelope of a rotor of the electric motor.

A front grease retention unit is provided under a front plunger and a wall is provided between the retention unit and a gear accommodation unit. Furthermore, a front grease receiving member is provided under the front plunger and a front metal bearing, and grease falling into the front grease receiving member is sent toward the outer circumferential face of the front plunger. The grease is pushed out by using the vertical oscillation of a front metal anchor bolt in orbital mode. A rear grease receiving member is provided under a rear plunger and a rear metal bearing, and grease falling into the rear grease receiving member is sent toward the outer circumferential face of the rear plunger. The grease in a grease reservoir groove is pushed out by using the vertical oscillation of a rear metal anchor bolt in orbital mode.

A continuously variable transmission changes a gear ratio by changing a groove width between the fixed side pulley half body and the movable side pulley half body in each of the driving pulley and the driven pulley using pulley pressure. At least any of a drive shaft of the driving pulley and a driven shaft of the driven pulley includes a pulley pressure supply oil passage for supplying pulley pressure to the movable side pulley half body, a lubricating oil passage provided on a downstream of the pulley pressure supply oil passage to supply oil as a lubricating oil to an endless member, and a flow control valve that is provided between the pulley pressure supply oil passage and the lubricating oil passage and operates according to pulley pressure.

A hydraulic arrangement for a vehicle transmission includes a hydraulic pump for providing a system pressure for a first hydraulic system circuit and a lubrication pressure for a second hydraulic lubrication circuit. The arrangement also includes a control valve connected between a pump outlet of the pump and the two hydraulic circuits and has two different switching positions. The control valve, depending on its switching position, acts as a hydraulic connection between the pump and the system circuit or between the pump and the lubrication circuit.

A control device for an automatic transmission is provided, which includes a vehicle-propelling friction engagement element configured to be engaged when a vehicle starts traveling, an other friction engagement element, a vehicle-propelling friction engagement element temperature detector configured to detect a temperature of the vehicle-propelling friction engagement element, an input torque detector configured to detect an input torque inputted into the automatic transmission, and a control unit comprising a lubricant supply control logic configured to control supply of lubricant to the vehicle-propelling friction engagement element and the other friction engagement element. The lubricant supply control logic switches the supply amount of lubricant to the vehicle-propelling friction engagement element according to the temperature of the vehicle-propelling friction engagement element, and switches the supply amount of lubricant to the another friction engagement element according to the input torque.

A transmission for a vehicle. The transmission includes a housing and a valve block arranged in the housing, and a parking lock mechanism. The parking lock mechanism has a wheel rotationally locked to a shaft of the transmission, a pawl and a hydraulic actuator arranged for engagement of the wheel and the pawl for locking the shaft. The actuator is hydraulically connected to the valve block such that the actuator is supplied by hydraulic fluid from the valve block.

A vehicle transfer case is provided having a housing, a primary shaft rotatably mounted within the housing, a secondary shaft selectively driven by the primary shaft, a hub torsionally fixed with the primary shaft, a clutch housing selectively torsionally connected with the hub via a friction pack, an engagement wheel torsionally fixed with respect to the clutch housing and torsionally connected with the secondary shaft via a flexible torsional force member, the friction pack, upon engagement, causing the clutch housing to be selectively connected with the hub, a reservoir system fixed with respect to the housing capturing lubricant energized by result of the operation of the flexible torsional member, the reservoir system delivering splashed lubricant to a reservoir system, and an Archimedes' screw pump delivering lubricant from a sump adjacent to the secondary shaft to the secondary reservoir system.

A fan housing includes a housing body for accommodating fan components and an outer casing which surrounds the housing body in circumferential direction. The housing body has at least two webs extending in a circumferential direction on the radial outer side. The outer casing has at least two ribs extending in the circumferential direction on the radial inner side. The ribs, in the assembled state, between the housing body and the outer casing, form a channel circulating in the circumferential direction for receiving and holding a heating band. The outer casing has at least one guiding rib directed in the radial direction toward a housing body as well as into the channel and extending in the circumferential direction.

A fluid pump includes a pump element in communication with an inlet and an outlet. Rotation of the pump element generates a suction at the inlet and pressure at the outlet. The suction and pressure cooperate to move a fluid through a fluid path. An accessory fluid path is in communication with the inlet and outlet. The accessory fluid path includes a thermistor in communication with the accessory fluid path. The thermistor monitors a temperature of the fluid within the accessory fluid path.
