ZF 8HP transmission

Template:Use American English Template:Use dmy dates Template:Infobox automobile

8HP is ZF Friedrichshafen AG's trademark name for its 8-speed automatic transmission models with hydraulic converter and planetary gearsets for longitudinal engine applications. The 8HP is the first transmission to use this 8-speed gearset concept. It has become the consensus benchmark for torque-converted automatic transmissions.

The GM 8L transmission is based on the same globally patented gearset concept. While fully retaining the gearset logic, it differs from this only in the patented^[1] arrangement of the components with gearsets 1 and 3 swapped.^[2]

History

Designed and first built by ZF's subsidiary in Saarbrücken, Germany, it first was introduced in 2008 on the BMW 7 Series (F01) 760Li sedan fitted with the V12 engine. BMW remains a major customer for the transmission. It is now in its fourth generation and has been adopted by more than 20 brands from BMW to Ram; by 2023 over 15 million units have been produced.^[6]

Another major customer is Stellantis, who both received a license to produce the transmission and set up a joint-venture plant with ZF. Stellantis has built the transmission at its Kokomo Transmission plant since 2013 under their own brand name, the Torqueflite 8.^[7]^[8] The joint venture plant in Gray Court, South Carolina opened in 2012.^[9]

Specifications

2008: Pilot series

The 8HP 70 transmission with the gearset 4 in 23-85-teeth-configuration was the pilot series and therefore without generation designation. It was first used in the BMW 7 Series (F01) 760Li, has a torque handling limit of Template:Convert, and weighs Template:Convert.^[10]

2010: 1st generation

In addition to the rear-wheel drive variant, two different four-wheel drive versions were available, with a version destined for Volkswagen Group applications using a Torsen centre differential.^[11] It is able to encompass a torque range from Template:Convert to Template:Convert, and is available for use in middle-class cars through to large luxury sport utility vehicles.^[11]

Since gearset 4 meshes in almost all gears up to and including 5th gear, large gear wheels are advantageous for durability. As the very high ratio 1st gear is formed exclusively by gearset 4, its sun gear is unusually small. For this reason, this gearset was enlarged by over 20% when the 1st generation was introduced, even if this advantage had to be given up again immediately when the 2nd generation was introduced in order to increase the total span.

2014: 2nd generation

Efficiency improvements over the pilot design and the first generation include a wider ratio span of 7.81, reduced drag torque from the shift elements, reduction in required oil pump pressure, and broadened use of the coasting and start-stop systems.^[12] ZF estimated fuel economy improvement over first generation to be 3%. Refinements were also made with respect to vibration.

2018: 3rd generation

Major improvements are total span of 8.59 and a fuel economy improvement of 2.5% compared to the second generation. There are several options in maximum torque available, also the gearbox is available with mild hybrid and plug in hybrid options: With Template:Convert and Template:Convert supporting boosting and recuperation in combination with 48 Volt technology up to Template:Convert and Template:Convert for usage with higher voltage.^[13]

2022: 4th generation

Major improvement is the transition to a versatile modular system that allows vehicle manufacturers to comprehensively and flexibly electrify their models as required. Plug-in Hybrid options with up to Template:Convert and Template:Convert are capable of saving up to 70% of carbon emissions compared with a purely conventional variant of the 8HP according to the Worldwide Harmonised Light Vehicles Test Procedure (WLTP).^[4] In addition, a modification to gearset 3 increased the reverse gear ratio, making it less disadvantageous. With this gearset concept, the already disadvantageously large step from 7th to 8th gear is further increased, albeit only slightly.

Planetary gearset concept

Improved fuel economy

The main objective in replacing the predecessor model was to improve vehicle fuel economy with extra speeds and a wider gear span to allow the engine speed level to be lowered (downspeeding), which is a decisive factor in improving energy efficiency and thus reducing fuel consumption. In addition, the lower engine speed level improves the noise-vibration-harshness comfort and the exterior noise is reduced. Compared to the 6-speed ZF 6HP transmission it uses 12% less fuel, and 14% less than a 5-speed transmission.^[14]^[15] Due to changes in internal design, the shift times have reduced to 0.2 seconds.

Reduced manufacturing complexity

In order to avoid a further increase in manufacturing complexity while expanding the number of gear ratios, ZF switched from the conventional design method—in which the planetary gearset concept was limited to a purely serial or in-line power flow—to a more modern design method that utilizes a planetary gearset concept with combined parallel and serial power flow. This was only possible thanks to computer-aided design and has resulted in a globally patented gearset concept. The resulting progress is reflected in a better ratio of the number of gears to the number of components used compared to existing layouts. The 8HP has become the new reference standard (benchmark) for automatic transmissions.

Quality

The ratios of the 8 gears are relatively unevenly distributed in all versions. Particularly noticeable are

the too small step between 3rd and 4th gear
and the too large step between 7th and 8th gear.

This cannot be eliminated without affecting all other gear ratios. On the other hand the selected gearset concept offers 2 to 3 gears more than conventional transmissions of comparable manufacturing costs, which more than compensates for the weaknesses.

Additionally, the gearset brings the ability to shift in a non-sequential manner – going from gear 8 to gear 2 in extreme situations simply by changing one shift element (actuating brake B and releasing clutch D).^[16]
