Title: Mechanical rear-axle steering gear of a motor vehicle with four-wheel steering
Inventor: REISDORF KLAUS ING GRAD
IPC: B62D7/15
Filed: 1989-02-16
Abstract: Known mechanical rear-axle steering gear for motor vehicles with four-wheel steering, which steering gear causes the steerable rear wheels to be deflected in the same direction in the case of relatively small locking of the steering wheel and in opposite directions in the case of relatively large locking of the steering wheel, the maximum deflection in opposite directions being perceptibly greater than the maximum deflection of the rear wheels in the same direction, are comparatively costly and to a certain extent have difficult movements and require considerable constructional space. The new mechanical rear-axle steering gear is, in contrast, intended to be simple and compact in design and to have easy movements and, furthermore, to permit considerably larger maximum deflection in opposite directions than maximum deflection in the same direction. The input shaft of the rear-axle steering gear is rotatably mounted in a hub component which itself is mounted so as to be pivotable about a pivot axis which extends approximately vertically at the start of the input shaft and perpendicularly with respect to its longitudinal axis. The free end of the input shaft which bears an eccentric crank pin bears a pinion which is in constant toothed engagement with a fixed, curved toothed rack which extends in an approximately horizontal plane arranged perpendicularly with respect to the longitudinal axis of the input shaft and whose central curvature point lies in the pivot axis of the hub component. <IMAGE>

Patent DE-3909932-A1 (DE)
Inventor: ABTHOFF JOERG DR ING
IPC: F02M25/07
Filed: 1989-03-25
Abstract: A soot particle fitter 5 in the exhaust line 3 of a supercharged diesel engine 1 is regenerated by increasing the exhaust gas temperature. So that an adequate temperature may be achieved at all engine speeds and loads, the speed and load are monitored by unit 19, which controls a valve 7 to bypass all exhaust gas round the supercharger turbine 4 at low loads, thus avoiding cooling of the gas by expansion. At higher loads a variable portion of gas bypasses the turbine. In addition throttle valve 10 and valve 12 in exhaust recirculation line 11 are controlled to raise the temperature at low loads, and for the engine intake air is variably heated by heat exchanger 34 and mixing valve 35. <IMAGE>
