摘要:
A method of operating a vehicle drive train (1) comprising a combustion engine (2), a turbo charger (22) assigned to the combustion engine, a mechanism for the injection of additional compressed air into an air intake system (8) of the combustion engine (2), a start and shift clutch (60), and a transmission (62). To optimally prepare and execute a start procedure of such an equipped vehicle, additional compressed air is only injected into the air intake system (8) of the combustion engine (2) if, depending upon the actual operating situation of the vehicle, the injection of additional compressed air benefits the safety of the driver, fuel consumption, drive comfort and/or the clutch wear.

摘要:
A method to operate a vehicle drive train comprising a combustion engine, a turbo charger assigned to the combustion engine, a mechanism for injecting additional compressed air into an air intake system of the combustion engine and a transmission. The method enables practical use of a compressed air injection mechanism, in the drive train, and comprises the step of controlling the time, the duration, the pressure and/or the volume of the additional compressed air, to be injected into the air intake system of the combustion engine, depending upon the performance request of the driver, the actual rotational speed and load condition of the combustion engine, the speed of the vehicle, and the procedures of the gear ratio change of the transmission.
摘要:
A known device for increasing the functional reliability for a hydraulic circuit of a hydraulic clutch having one pressure reservoir and one release cylinder which comprises a primary piston, a secondary piston and a compensation volume is to be further developed in the sense that when the vehicle is at a standstill and the parking brake released, an unintentional release of the clutch is prevented. According to the invention there is used for the purpose a pressure-monitoring/pressure-supply device (28) which determines a reference operating pressure and establishes a static pressure which in case of system errors allows only a displacement of the secondary piston (16) such that the contact pressure of the clutch discs against each other is still sufficient to hold the vehicle at a standstill.
摘要:
One vehicle clutch (6) is situated in a vehicle between a prime mover (2) and a transmission (4) and is controlled according to the rotational speed of the prime mover (2). As centrifugal clutch, the vehicle clutch (6) has elements (26, 32) which cause a variable torque transmission according to the rotational speed of the prime mover (2). The vehicle clutch (6) is actuatable without an externally actuated actuator, is the only clutch located between prime mover (2) and transmission (4) and is provided as starting clutch without possibility of interruption of traction during shifting operations.

摘要:
A device for rendering a hydraulic actuating device operational. A motor vehicle clutch with an emitter-receiver system located in the transmission path of the actuating device comprising two pistons whose positions, relative to one another, can vary as a function of the desired operating behavior of the actuating device and is developed further such that in relation to the emitter-receiver system that is to be filled with fluid, operationality can be established comparatively quickly and by simple way. A fluid supply unit (24) comprises one impulse valve (25) that serves to release an essentially constant volume flow, acted upon by an impulse valve control device (26) which is constructed such that the fluid volume flow released by the fluid supply unit (24) and flowing into the emitter-receiver system (5) does not exceed a limiting volume flow QK.

An actual operating time is determined by an approximation method within the scope of the method for determining the actual operating time of a hydraulic, electrohydraulic or electric component of a motor vehicle or of a working machine within a reference time or a monitoring period.
摘要:
This invention relates to a pan head (1) for supporting a device, preferably a film or television camera (2), having a stator (6) and a rotor (7) swiveling about a pitch axis (A) of the stator (6), whereby the rotor (7) supports the device (2). To permit determination of the torque between the rotor and stator with the device fitted on, and thus to facilitate e.g. the "balancing" of the fitted device in the zero position of the rotor (7), a torque sensor (31) is integrated into the pan head (1) for detecting the torque in several pitching positions of the rotor (7).
