Abstract
A retrofit kit for an Allison transmission for converting a standard Allison Transmission into a variable speed hybrid using external pressure. The retrofit kit for an Allison transmission includes a main housing; gear sets being disposed in the main housing and including rotational members; clutches being in operable communication to the gear sets; a hydrostatic pump being in operable communication to at least one of the rotational members and having ports; and a fluid circuit being in fluid communication to the hydrostatic pump through the ports and to at least one of the clutches.
Claims19
A retrofit kit for an Allison transmission comprising:
- a main housing;
- gear sets being disposed in said main housing and including rotational members, said gear sets including a first rotational member and a second rotational member and also including a ring gear being rigidly connected to said second rotational member;
- clutches being in operable communication with said gear sets;
- an axial piston pump being in operable communication with at least one of said rotational members and having ports, said second rotational member being in operable communication with said axial piston pump;
- and
- a fluid circuit being in fluid communication with said axial piston pump through said ports and to at least one of said clutches.
A retrofit kit for an Allison transmission comprising:
- a main housing;
- gear sets being disposed in said main housing and including rotational members, said gear sets including a first rotational member being in operable communication with a drive source, and also including a first planetary carrier being connected to said first rotational member, and further including a first set of planetary gears being rotatably carried by said first planetary carrier, and also including a sun gear being in operable communication with said first set of planetary gears, said gear sets further including a third rotational member being engaged to said sun gear, said gear sets also including a second planetary carrier;
- clutches being in operable communication with said gear sets, said clutches including a cone clutch being engaged to one of said planetary carriers and to said third rotational member and also including a clutch lockup member being engaged to one of said planetary carriers and to said third rotational member and also being engagable to said cone clutch;
- an axial piston pump being in operable communication with at least one of said rotational members and having ports;
- and
- a fluid circuit being in fluid communication with said axial piston pump through said ports and to at least one of said clutches.
