Abstract
The invention relates to a transmission for a drive train of a motor vehicle, having a shaft section, to which a torque measurement device, designed to measure a torque applied to the shaft section is attached, wherein an electronics unit connected to the torque measurement device is received radially within the shaft section. The invention further relates to a drive train for a motor vehicle, having a transmission.
Claims17
A transmission for a drivetrain of a motor vehicle, the transmission comprising:
- a shaft section;
- a torque measurement device mounted on the shaft section, the torque measurement device being configured to measure a torque applied to said shaft section;
- and
- an electronics unit connected to the torque measurement device that is housed radially inside the shaft section,
- wherein the transmission is a continuously variable transmission and further comprises a drive plate pair and a driven plate pair, and an endless traction mechanism that actively interconnects the drive plate pair and the driven plate pair, and the shaft section is locked in rotation with one of the plates of the drive plate pair.
A transmission for a drivetrain of a motor vehicle, the transmission comprising:
- a shaft section;
- a torque measurement device mounted on the shaft section, the torque measurement device being configured to measure a torque applied to said shaft section;
- an electronics unit connected to the torque measurement device that is housed radially inside the shaft section;
- and
- a data transmission unit arranged between a housing of the transmission and the shaft section that can rotate relative to the housing and is connected to the electronics unit,
- wherein the data transmission unit comprises a bearing configured for transmitting data.
A continuously variable transmission for a drivetrain of a motor vehicle, the transmission comprising:
- a shaft section;
- a torque sensor mounted on the shaft section, the torque sensor being configured to measure a torque applied to said shaft section;
- and
- an electronics unit housed radially inside the shaft section and that receives a signal from the torque sensor and is adapted to output a data transmission signal that represents a measured torque.
