摘要:
The invention relates to a mounting device (01) for mounting a driven and/or a drivable wheel of a vehicle. The mounting device (01) makes it possible to measure a drive torque or a drag torque that acts between a wheel and a driveshaft. The torque is transmitted from the driveshaft to the wheel by means of radial teeth (12) on a bearing inner ring (03), where there is a pressure-sensitive measuring element (17) to measure axial forces as a characteristic of the particular effective torque. In addition, the invention relates to a device to control the distribution of the drive and drag torques acting on the drivable wheels of a vehicle. To measure the drive and drag torque distribution, there is a sensor unit (17, 18) on each drivable wheel to measure the torque acting on each wheel.

A device for detecting load torque on an electric motor, adapted for use for a device for rotating a predetermined load by the motor. The device for detecting load torque can appropriately and highly accurately detect reaction of such a load, or load torque, acting on the drive output shaft of the motor. The motor is fixed to an external casing, which is a specific holding section or a stationary section, to facilitate production of the device, and a support structure is stably placed. The drive output shaft (14) is projected from one end of a housing of the motor (10), a sleeve body (16) is placed so as to surround the drive output shaft, a flange (18) is formed at one end of the sleeve body, and the flange is fixed to the one end of the housing. The other end of the sleeve body is integrally formed as an internal gear section (22) of a reduction mechanism (20) having a planetary gear (21). A strain gauge (24) is attached to the outer periphery of the sleeve body.

Le dispositif de mesure de couple s'intercale entre un ensemble moteur (2) et un ensemble charge (3) et comprend
un moyen de mesure du couple transmis entre l'ensemble moteur (2) ou l'ensemble charge (3), un moyen de mesure du couple absorbé ou restitué par l'accélération angulaire des masses rotatives situées entre le moyen de mesure du couple transmis et l'endroit où le couple est recherché. un moyen pour additionner algébriquement la valeur de ces deux couples, le résultat de cette addition algébrique étant représentatif de la valeur du couple recherché à l'endroit prédéterminé, cette valeur serait celle obtenue si la mesure pouvait être effectuée en régime rigoureusement stationnaire.
摘要:
A torque sensor system for a pedelec includes an annular gear (6), a planetary gear train (5), a sun gear output shaft (2), a pressure conversion device (9) and a signal processing component (8). The annular gear (6), the planetary gear train (5), and the sun gear output shaft (2) are engaged in turn. The annular gear (6) is driven by the planetary gear train (5), and an applied force signal is transmitted to the signal processing component (8) via the pressure conversion device (9) at an edge of the annular gear (6). The applied force signal is converted to an electric signal by the signal processing component (8) and transmitted to a controller, so as to realize a torque feedback. As a result, a problem that a speed sensor is not applicable to a pedelec when climbing is solved; in addition, as the system has a simple and compact structure, and reliable torque data, a user will feel real and comfortable when riding. Moreover, a pedelec with the torque sensor system is provided.

The present application relates to an input torque measuring device for a drive train of a bicycle. The drive train includes a first crank arm and a second crank arm. An inboard end of each crank arm is rotatably mounted to the bicycle at a bottom bracket of the bicycle. At least one chain ring is configured to rotate a driven wheel of the bicycle. A spider is connected to the first crank arm adjacent the bottom bracket and extends out to the at least one chain ring. The spider is configured to transmit force applied to the crank arms directly to the at least one chain ring. The spider may include a plurality of sensors configured to respond to the force applied by the spider to the at least one chain ring.; The sensors produce an electronic signal relative to the force transmitted by the spider to the at least one chain ring and a processor configured to receive the electronic signals from each sensor of the spider.
