摘要:
A powertrain system for a commercial electric vehicle includes an electric motor, a multi-speed transmission, and a drive line. A reducer assembly is added prior to connection to the drive line to decease the rotational speed generated by the electric motor prior to being transmitted to the drive line. The reducer assembly can be placed before the multi-speed transmission input, after the multi-speed transmission output, or somewhere in between those two locations. The reducer assembly includes a reducer gearset for decreasing shaft rotational speed. The reducer assembly may include adjacent idler gears to reduce the pressure load on the gear teeth of the reducer assembly.

A transmission for an agricultural or heavy load vehicle is provided, and includes a central drive shaft, at least one planetary gearset comprising a planet carrier, at least one output drive element, and one brake device. The drive shaft is connected to the output drive element via the planetary gearset. The brake device is located between the planet carrier and the output drive element in the form of a ring gear, such that the output drive element can be coupled to the planet carrier via the brake device.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. A shift actuator selectively couples the input shaft to the main shaft by rotatably coupling gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. An integrated actuator housing includes a single external power access for the shift actuator. A controller interprets a shaft displacement angle, determines if the transmission is in an imminent zero or zero torque region, and performs a transmission operation in response to the transmission in the imminent zero or zero torque region.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.

A retaining member is provided and attached to a bevel gear in order to allow the bevel gear to be attached, prior to assembly, to a bearing adapter. The retaining member is provided with first and second protuberances that extend radially outwardly from diametrically opposite positions on the retaining member so that the protuberances can be inserted through first and second slots in a generally cylindrical member, or bearing adapter, during the assembly of individual components to form a subassembly. Since the bearing adapter is attached to a bearing carrier, misalignment of the protuberances and the slots allow the bevel gear and several other assorted components to be retained in contact with the bearing carrier so that the components are not free to move in axial directions away from each other to allow separation of these components. Since the individual components are retained in axial positions relative to each other and relative to the bearing carrier, insertion of this subassembly into a gearcase makes the assembly much easier than would otherwise be possible.

A cover of a joint part between an engine and transmission is provided. Preferred cover systems of the invention include a transmission-side vertical wall for closing a tool insertion space; and an oil pan mounting part at an opposing side of the transmission-side vertical wall that fits with the transmission-side of an engine oil pan. Preferred cover systems of the invention can at least substantially preclude exterior impurities from entering into the transmission and effectively insulate noise and vibration of the transmission from being transmitted to the exterior or the engine.

摘要:
Transmission device for vehicles with a front cab, with front-wheel drive, and with a chassis to which bodywork may be added. This device relates more particularly to vehicles intended, from the outset or after conversion, to take a lowered platform, especially showman's vehicles, mobile laboratories, or travelling sales vehicles. The device, designed for a front-wheel drive motor vehicle with a front cab and a lowered chassis, comprises a front axle assembly and a gearbox, the output shaft of which is arranged longitudinally with respect to the axis of the vehicle, behind the gearbox. It includes a casing, a first gear which can be mounted on the output shaft of the gearbox, a second gear mounted on a transfer shaft towards the front axle assembly and an intermediate gear permanently in mesh with the first gear and the second gear.
