摘要:
The invention concerns a control arrangement for an automatic electrohydraulically controlled transmission. In order to reduce expenditure on parts and assembly, the hydraulic control system and electronic control system are mounted directly adjacent each other and plug-in connections are provided between the solenoid valves of the hydraulic control system and the electronic control system. The hydraulic control system (20) substantially comprises two duct panels (28,30) in which control ducts, piston slides and solenoid valves (not shown) are disposed for controlling the conical plates and couplings of the transmission. The pressurized hydraulic fluid is fed directly into these duct panels from the pump (29). The electronic control system (22) has a single central connection (36) which is secured in the transmission housing cover (42) by an annular seal. Rotational speed sensors for the transmission shafts and temperature and pressure sensors are integrated into the control unit.

A change-speed transmission in the power train of a motor vehicle has a planetary gearing and coaxial radially inner and outer disc clutches, namely a direct clutch and a reverse clutch. At least that clutch which is engaged (i.e., in use) is cooled by a lubricant for the planetary gearing, and the flow of coolant to the clutches is regulated by the axially movable pressure plate of one of the clutches. A jet pump conveys lubricant from the sump in the transmission case into an axially extending channel of the input shaft of the transmission, and such channel forms part of a system of passages which supply coolant at least to that clutch which is then in use to transmit torque from the input shaft to an output element of the transmission.

The invention relates to a device for shifting changes in the transmission ratio of a vehicle transmission. Said device comprises at least one axially movable and/or rotatable shifting element and an electrical position identification of the shifting element. At least one magnet which generates position signals in combination with a stationary sensor is disposed on the shifting element. In order to create a device that is advantageous regarding production and design, the magnet is formed directly by a magnetic area on the shifting element.

The invention relates to a propulsion system for all-wheel drive motor vehicles, having a device for propulsion distribution to the front and the rear differential which transmit the drive output to the wheels assigned at the time, and with a device for coupled, variable distribution of the propulsion forces in the transverse and longitudinal directions of the vehicle depending on the operating situation of the vehicle for influencing the driving behavior, especially for improving the driving agility and driving stability. In the process the rear differential (18) is combined with an overriding drive (22), by means of which the drive torques can be shifted to the rear wheels (20) in alternation in the transverse direction of the vehicle, the rpm ratio or rpm error being dictated by means of the overriding drive (22) at the design point so that at a given curve radius which is assigned to the design point and which does not correspond to the narrowest curve, a reversal of the direction of the rotational speed difference takes place and thus the torque is not shifted to the wheel on the outside of the curve. By means of the propulsion distribution device (24, 26; 44, 46; 52) the drive torques can be shifted in alternation between the front differential (14) and rear differential (18) in the longitudinal direction of the vehicle.

The invention relates to a drive unit for motor vehicles, comprising an internal combustion engine, a transmission which is mounted downstream therefrom and is provided with an integrated differential, and a separating clutch that is disposed between the internal combustion engine and the transmission. The differential is driven via a bevel wheel and a bevel-gear drive comprising a drive pinion on an output shaft of the transmission. In order to create a drive unit that is advantageous regarding structure and efficiency, the bevel wheel (48) of the differential (16) is placed laterally from the separating clutch (26) from a vertical perspective and partly protrudes (A) therefrom in an axial direction.

Methods of permanent shaping and volumizing hair that are gentle and prevent overcurling are described. In one method using curlers to curl the hair, an alkaline permanent shaping composition having a pH of 7.6 to 11 and including a hair keratin-reducing substance is applied to the hair and allowed to act on the hair for 5 to 30 minutes at room temperature or for 2 to 20 minutes at an elevated temperature. Then the hair is optionally rinsed with water and subsequently with an acidic aqueous intermediate rinse, which has a pH of 2 to 6.5 and includes an aliphatic organic acid. Next the hair is wound onto curlers, after which the hair is allowed to rest for 30 minutes at room temperature or 20 minutes at an elevated temperature. After the resting period the hair is treated with an oxidant-based fixative, which can be a solution of hydrogen peroxide, and the curlers are removed. The hair is subsequently rinsed with water or washed with a shampoo to remove the fixative and combed into a hair style. For methods of uncurling hair the method is similar, but the step of winding on curlers is replaced by a step of combing the hair out and the acidic aqueous intermediate treating agent is in the form of a gel, cream or paste.
