A parking mechanism includes an actuator having a manual shaft rotating around the first axis, a flange provided on an outer periphery of the manual shaft, a cam rod having a coupling portion coupled to the flange and a rod body moveable along a second axis orthogonal to the first axis with a movement of the flange, a coil spring attached to the rod body, a cam that is attached to the rod body and moves along the second axis by motion of the rod body transmitting via the coil spring, a pawl member having a meshing portion and operating with a movement of the cam, and a parking gear having a tooth portion with which the meshing portion meshes. The self-holding torque of the actuator is larger than the torque applied to the manual shaft at the time of maximum compression of the coil spring.

Parking mechanism and method of assembling parking mechanism

A parking mechanism includes: a parking gear rotatable about a major axis with a wheel of a vehicle; a parking pawl rotatable about a first axis parallel to the major axis, and having a meshing portion facing a tooth portion of the parking gear; a cam rod extending and operating along a first direction orthogonal to the major axis; a cam attached to the cam rod, contacting the parking pawl, and movable along the first direction with the operation of the cam rod to rotate the parking pawl around the first axis and move the meshing portion toward the parking gear; a U-shaped sleeve open toward the parking pawl and supporting the cam; and a pawl stopper to contact and restrict movement of the parking pawl toward the cam rod. The cam rod is inserted into the sleeve. The pawl stopper is between the parking pawl and the cam rod.

Parking mechanism and drive apparatus

A drive apparatus includes a power assembly rotatable about a first axis, a transmission to transmit power of the power assembly, and a parking assembly provided in the transmission. The transmission includes a first gear rotatable around a first axis, a second gear to mesh with the first gear and rotatable around a second axis, a third gear to rotate around the second axis together with the second gear, and a fourth gear to mesh with the third gear and rotatable around a third axis. The parking assembly includes a parking gear rotatable around the first axis together with the first gear, a parking pawl that includes a meshing portion and is rotatable around a fourth axis, and a drive assembly to rotationally move the parking pawl around the fourth axis and operate the parking pawl.

Drive apparatus

A biogas combustion system that obtains a stable output and saves energy is realized. A combustion system comprises a separation portionthat removes carbon dioxide from a treatment target gas containing a mixture gas containing methane as a main component and containing carbon dioxide to obtain methane gas of a high purity in which at least a content of carbon dioxide has been reduced, and a combustion portionthat combusts the methane gas. The separation portionincludes a first treatment chamberand a second treatment chamberseparated from each other by a separation membranetherebetween. The separation membraneselectively allows the carbon dioxide in the treatment target gas supplied to the first treatment chamberto pass therethrough to the second treatment chamberto obtain a first separation gas having a higher methane purity than the treatment target gas in the first treatment chamberand a second separation gas containing the carbon dioxide in the treatment target gas in the second treatment chamber

Combustion system

A power generation system comprises a fuel gas supply devicefor controlling methane concentration or carbon dioxide concentration in a mixed gas MG containing methane and carbon dioxide within a setting range for the concentration in the fuel gas of a gas engine, and for supplying the mixed gas MG to the gas engineas the fuel gas, and a gas concentration sensorfor measuring the carbon dioxide concentration or the methane concentration of the mixed gas MG. The fuel gas supply devicecomprises a carbon dioxide removal devicefor removing carbon dioxide in the mixed gas MG, and an operating condition control devicefor controlling an operating condition that affects an increase or decrease of a carbon dioxide removal rate of the carbon dioxide removal device, and the operating condition control devicecontrols the operating condition of the carbon dioxide removal devicebased on the measurement result of the gas concentration sensor, thereby controlling the concentration of methane and carbon dioxide in the mixed gas.
