    摘要: The present invention relates to a torque sensor (1) comprising a body (2), at least one airtight chamber (3) provided in the body, a pressure sensor (4) measuring 1 the pressure in said at least one airtight chamber, and a pressure to torque converter (5) connected with the pressure sensor. Each airtight chamber is arranged to change its volume when the body is subjected to a torque, wherein the volume change causes a change of pressure of the enclosed air in the airtight chamber. The change of pressure is detected and converted to the corresponding torque.

    摘要: In a torque sensor of an electric power steering device, a natural and comfortable feeling to a driver (driver) is achieved by increasing the physical quantity of the torque sensor around the center of the steering wheel (neutral position). A torsion bar (3) for use in the torque sensor includes a core torsion bar (3A) and a tubular torsion bar (3B). The tubular torsion bar (3B) includes a pair of torsion tubular bar parts (3Ba, 3Bb), accommodates the core torsion bar (3A) in its inside, secures both ends of the core torsion bar (3A) in its inside, and the pair of tubular torsion parts (3Ba, 3Bb) mesh and couple each other by meshing teeth, when the core torsion bar (3A) twists a predefined rotational angle, so that a single torsion bar is configured. The elasticity of the tubular torsion bar (3B) is larger than that of the core torsion bar (3A).

    摘要: Overload protection device for torque measuring transducers comprising a measuring axle (1) intended for a certain maxi­mum measurement range. According to the invention the mea­suring axle is connected with a second input axle (3) by means of a claw clutch (4,5) which is prestressed by a spring (6). A surrounding housing (2) may suitably be jour­nalled riding on said axles and be prevented from rotating by a link to a fixed point. The housing is formed with an inwardly-directed brake flange (10) which, in the case of an unloaded axle, is spaced from the driving clutch half (4) by a distance considerably smaller than the height of the teeth of the claw clutch. The top angle alpha of the claw clutch and the force of the spring (6) are adapted such that the driving clutch half (4) starts moving towards the brake flange in the case of a torque load on the measuring axle which, with a satisfactory margin, exceeds the maximum mea­suring torque in either torque direction. In the case of a somewhat greater overload torque, the driving clutch half is pressed against the brake flange and an increasing part of the input torque is thus diverted on the housing.

    摘要: The invention relates to a twisting torque sensor, comprising a transmission shaft (12) subjected to the torque to be measured, a reference shaft (14), and a device for measuring an angular deformation representing the torque to be measured between the two shafts. The torque sensor is characterised in that the transmission shaft (12) comprises a bore (24) extending from one end of the transmission shaft (12), referred to as input (28) of the shaft, to an opposite end, and in that the torque sensor comprises an enclosure (22) for confining the temperature of the two shafts, and a fluid circulation circuit including a portion made up of said bore (24), an injector (32) for injecting the fluid into the bore (24) at said input (28) of the shaft, and a fluid temperature sensor (34) in the fluid circulation circuit, the measured temperature being intended for correcting the torque measurement.

    摘要: The invention relates to a method for determining a torsional moment of a wheelset shaft of a rail vehicle during the operation of the rail vehicle. The wheelset shaft has a shaft and two wheels secured to ends of the shaft, said wheels being provided for rolling on two rails. A model is used to calculate a torsional moment which acts on the wheelset shaft, and the model is based on a torsional vibration of the wheelset shaft at a specified slip action point. The torsional moment acting on the wheelset shaft is ascertained using the energy of the torsional vibration of the wheelset shaft at the slip action point and using a damping energy which acts on the torsional vibration of the wheelset shaft.
