Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0018] The present invention provides such Figure 1-4 The new 7-speed automatic transmission shown includes three sets of planetary rows. From left to right, the first row of single planetary wheel planetary row, the second row of single planetary wheel The planetary row is composed of a sun gear, a ring gear and a planet carrier. In the first row of single planetary gear planetary row, the ring gear is a constant input (that is, the ring gear and the input s...

Abstract

The invention discloses a novel 7-speed automobile automatic transmission. The novel 7-speed automobile automatic transmission comprises three planet rows, sequentially, the first single-planet wheelplanet row, the second single-planet wheel planet row and the third single-planet wheel planet row from left to right, wherein the planet rows are composed of sun wheels, gear rings and planet carriers; in the first single-planet wheel planet row, the gear ring is normally connected with an input shaft, and the sun wheel is normally connected with a transmission shell; the three planet rows are connected in series and parallel; the second planet row and the third planet row are connected in parallel to form a Ravigneaux structure; the first planet row and the Ravigneaux structure are connectedin series; and the second planet row and the third planet row share the same planet carrier and the same gear ring. The novel 7-speed automobile automatic transmission can be designed as a front-engine automatic transmission, the front-engine automatic transmission has the advantages of small size and light weight, the total weight of vehicles can be decreased, and fuel consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of automobile transmissions, in particular to a new 7-speed automatic transmission for automobiles. Background technique [0002] As people have higher and higher requirements for the comfort of vehicles and the outstanding advantages of automatic transmissions, more and more vehicles are equipped with automatic transmissions. The rate of vehicles produced in the United States is equipped with automatic transmissions. The transmission rate reaches more than 75%, and the automatic transmission rate of vehicles produced in Japan reaches more than 70%, while the automatic transmission rate of vehicles produced in my country is about 55%. Most of the automatic transmissions on vehicles equipped in our country are dependent on imports, which seriously restricts the development of our country's automobiles. At present, most of the automatic transmissions equipped on cars are 6-speed and above automatic transmissio...
