Patent number: 5335743Abstract: A steering wheel (11) is fitted with a control (13) which, when operated in mutually independent control directions (41-45), controls the acceleration and deceleration of the vehicle, as well as upward and downward gear changing, and activates one of a number of cruise control functions. The control (13) may preferably be mounted immediately adjacent to the steering wheel rim (15) on the upper side of a wheel spoke (12), so that it may readily be operated by the driver's thumb without the necessity of releasing the grip on the wheel. Thus, the control incorporates all of the most essential driving control functions. The control according to the present invention encourages the driver to select, at an early stage, those accelerator and gear-change parameters which are most advantageous to economic driving or are most suited to the prevailing traffic conditions, the control actions required involving a minimum of manual movements.Type: GrantFiled: April 16, 1993Date of Patent: August 9, 1994Assignee: Saab Automobile AktiebolagInventors: Per Gillbrand, Hans Johansson, Per Johansson, Bengt Elgh

Patent number: 5314319Abstract: A hydraulic pump in the form of an oil pump for a vehicle engine has both its pinion, which is driven by the engine's crankshaft, and a ring-gear, which cooperates with the pinion, incorporated in an end-cover fastened to the end of the engine block. A cap is inserted in a collar on the side of the end-cover facing away from the engine and is only held in position there by means of a locking ring, which engages with a groove in the collar and presses the cap toward the engine. Outside the oil pump, a partly socket-shaped belt pulley is mounted on the crankshaft and its socket-shaped portion substantially grips the collar. Fitting and removal are thus simplified and engine overall length reduced. Simplified sealing also reduces oil leakage risks.Type: GrantFiled: October 30, 1992Date of Patent: May 24, 1994Assignee: Saab Automobile AktiebolagInventors: Per-Inge Nilsson, Per-Anders Bulow

Patent number: 5281188Abstract: In an internal combustion engine, there is arranged a belt transmission for driving an accessory device. In this connection, deflection members are arranged so that the drive belt for its driving bears against, for example, the flywheel of the engine. The deflection members are arranged so that the area enclosed by the drive belt lies outside the area which encloses the axis of rotation of the flywheel. By virtue of the fact that consequently the drive belt can be mounted without the drive belt needing to cross the axis of rotation, the belt transmission can simply be arranged at the rear side of the engine. This means that the axial extent of the engine can be reduced.Type: GrantFiled: September 23, 1992Date of Patent: January 25, 1994Assignee: SAAB Automobile AktiebolagInventor: Per Gillbrand

Patent number: 5251664Abstract: A check valve (4) with spherical, spring-loaded valve head (25) is used for pulsating flows, especially in a fuel injection system for Otto engines. As a result of low flow resistance, such check valves have had a tendency to cause noise when the valve head (25) strikes down against the valve seat (11) during pulsating of the flow caused by selective opening of the fuel injection nozzles. The valve head (25) is designed with a flange (7) downstream of the valve seat (11), and this flange (7) interacts with a narrow boring (13) during the first part of the opening stroke. Consequently, a secondary throttling (12) is formed, in addition to the primary throttling between the valve head (25) and the valve seat (11), which contributes to the valve head being forced away at a distance from the valve seat.Type: GrantFiled: September 11, 1992Date of Patent: October 12, 1993Assignee: SAAB Automobile AktiebolagInventors: Hans Arvidsson, Gert Bjerendal

Patent number: 5234388Abstract: A differential (1) has a housing (2) made in one piece with two side openings (10) via which parts can be introduced into and removed from the housing. The pinion gears and side gears rest against the inside of the housing via respective support members (17-20). At least for the pinion gears (13,14) there is in the support member (17, 18) a bearing member (22) of the roller bearing type and a support plate (21), where the bearing member is intended to cooperate with, on the one hand, a first bearing surface (25) on the support plate and, on the other hand, a second bearing surface (26) on the actual pinion gear. Assembly of the support member is made possible by means of the fact that the side (24) of the support plate which is to rest against the inside (16) of the housing is convex.Type: GrantFiled: February 26, 1992Date of Patent: August 10, 1993Assignee: SAAB Automobile AktiebolagInventor: Kjell Nordkvist

Patent number: 5202913Abstract: A communications unit with a telephone receiver is intended for fitting in a standardized recess for radio equipment in vehicles. The telephone receiver in a first user position lies protected in the recess. By use of an automatic or manually initiated ejection, the telephone receiver is caused to take up a second user position in which the receiver has another orientation and a more advanced position relative to the recess. In this second position the telephone receiver can be picked up from a telephone receiver holder for manual handling. The invention permits a safer handling of the telephone while driving, and without obstructing the accessibility to other vehicle controls in the vicinity of the recess when the telephone receiver is in its first user position.Type: GrantFiled: June 20, 1991Date of Patent: April 13, 1993Assignee: Saab Automobile AktiebolagInventors: Ulf Lang, John-Gustaf Gudmundson

Patent number: 5184522Abstract: A mechanical stepped gearbox comprises a number of gear wheel pairs (25-34) which interact with one another and are arranged on an input shaft (19), an output shaft (22), and a first side shaft (24). The gear wheel pairs can be selectively coupled in order to form different gear ratios. In addition to this, the gearbox comprises, arranged on a second side shaft (40), a gear wheel (39) which is used both in order to bring about a reverse gear and in order to transmit driving force to the first side shaft (24). The gearbox can thus be designed with short axial extend even when the gearbox comprises many gear steps.Type: GrantFiled: October 17, 1991Date of Patent: February 9, 1993Assignee: Saab Automobile AktiebolagInventor: Kjell Nordkvist

Patent number: 5105303Abstract: A covering element consisting of transparent material is designed with an electro-chromatic layer for control of the transmission of light through the covering element. An electrical power which is required for control of the electro-chromatic layer is obtained from a photo-electric layer integrated in the covering element. The photo-electric layer is arranged outside the electro-chromatic layer. By means of the arrangement, when the light is at its most intensive, a high voltage is obtained from the photo-electric layer and can be transferred to the electro-chromatic layer so as to in this connection reduce, at least to a considerable extent, the transmission through the covering element. The arrangement can, within vehicle technology for example, be used in a sun-roof in order to prevent heating up of an interior space in sunny weather. By means of the arrangement, the transmission is automatically adapted according to the light.Type: GrantFiled: September 27, 1990Date of Patent: April 14, 1992Assignee: Saab Automobile AktiebolagInventor: Bertil Ilhage
