A speed sensor of a rotatable output element of a transmission comprises a rotating tone wheel (33) and an inductive pick-up (29) comprising one of a drain plug, a fill plug or a level plug. The arrangement is suitable for providing a vehicle speed signal to a vehicle tachograph.

An apparatus includes a case that stores oil inside, wherein the case includes a drain hole that discharges the oil to an outside, and a tubular portion that protrudes in a direction intersecting a direction of gravity, and the drain hole opens in a direction intersecting the direction of gravity on the tubular portion.

A system and method for automatic oil exchange service for electric vehicle gearboxes. The system and method includes a mechanism for monitoring and reporting status of the oil change in the gearbox. This ensures that each oil change is kept track of, that the oil is the correct grade, and that the vehicle ends up with oil that has maximum properties, avoiding contamination and improving the life of the gearbox. The present invention may be integrated directly at the same place as an electric vehicle charging station, supercharger station, or at any battery swap station.

A system including a gearbox and a hydraulic machine connected by a working fluid circuit. The gearbox including a gearbox housing having first and second gearbox fluid passages integrated into the gearbox housing. The hydraulic machine including a case having first and second hydraulic machine fluid passages, the first and second hydraulic machine fluid passages being integrated into the case. A set of rotating elements enclosed within the case. The first gearbox fluid passage and the first hydraulic machine fluid passage align to form a feed passage to conduct fluid at a first pressure from a first source to the set of rotating elements. The second gearbox fluid passage and the second hydraulic machine fluid passage align to form a charge passage to conduct fluid at a second pressure from a second source to the set of rotating elements. The first pressure being less than the second pressure.

A gearbox housing includes a housing body enclosing a housing interior and having a passage opening for a gearbox output shaft surrounded by a connecting surface. A plurality of bores is formed in the housing body and extends through the housing body wall to fill oil into or drain it out of the housing interior, detect the oil level in the housing interior and vent the housing interior. The bores, which are provided as an oil filling opening, an oil draining opening, a venting opening and a level measuring opening during operation, are positioned in such a manner that they can be introduced into the housing body from two adjacent housing sides. This enables machining with a single clamping, with the result that changeover times are unnecessary and the housing body is consequently easy to manufacture.

A carrier assembly includes a first portion having a cover flange. A second portion is coupled with the cover flange. A first trunnion is coupled with the first portion, and a second trunnion coupled with the first portion opposite the first trunnion. A first trunnion rib is coupled with the first portion, wherein the first trunnion rib projects outward from the first portion. A second trunnion rib is coupled with the first portion, wherein the second trunnion rib projects outward from the first portion. The first and second trunnion ribs are offset from a trunnion centerline.

A machine for replacing used transmission or power steering fluid in a vehicle with new transmission or power steering fluid includes a frame having a housing. The machine includes a pair of service hoses that extend from the machine and connect to the vehicle for placing the machine in the fluid flow. New, used, and axillary fluid tanks are provided. A pump and a manifold are associated with two of the tanks. The pumps provide for the selective withdraw or insertion of fluid into or out of the tanks. A display on the housing presents an operator of the machine with various tasks or options the machine can perform. A processor controls activation of the pumps and other electrical components based on inputs received by the display. Scales are provided under one or more of the tanks for determining the amount of fluid going into and out of the tanks during the exchange process.

A gearbox filler assembly includes a cylindrical insert attached to an interior of a port disposed within a housing of the gearbox. The cylindrical insert has a first end disposed within the port, a second end extending outward from the port and is configured to receive a detachable filler cap, a retaining lip around at least a portion of a first interior circumference proximate to the first end, and a retaining slot around at least a second interior circumference between the retaining lip and the second end. A retaining ring is detachably coupled within the retaining slot. A cylindrical baffle is detachably retained between the retaining ring and the retaining lip.

There is provided a gear device including a motor having a motor shaft, a gear mechanism, a coupling that couples the motor shaft and an input shaft of the gear mechanism with each other, a first space accommodating the gear mechanism and holding a lubricant, a communication passage allowing the first space and a second space for accommodating the coupling to communicate with each other, and a blocking member disposed between the gear mechanism and the communication passage.

A torque multiplier module is disclosed for use with a wrench. The torque multiplier module may include a sealed housing having an input opening and an output opening, and a planetary gear arrangement disposed inside the sealed housing. The planetary gear arrangement may be configured to engage an external input received from the wrench via the input opening. The torque multiplier module may also include a drive fitting connected to the planetary gear arrangement and accessible via the output opening.
