Embodiment Construction

[0047] The present invention comprises two planetary gear sets and self-locking mechanism, starting clutch, and the first planetary gear set is made up of sun gear 4, planetary gear 2, internal gear 1 and planetary gear carrier 3, and the second planetary gear set is made of sun gear 44, Planetary gear 42, internal gear 41 and planetary gear carrier 3 constitute. The sun gear is connected with the planetary gears, and the planetary gear carrier of the two planetary gear sets is a whole. The self-locking mechanism is installed between the two planetary gear sets. The self-locking mechanism is composed of a swinging central gear 6, a free planetary gear 7, a swinging internal gear 8 and a connecting piece 9, a fixed pin 5 and a fixed pin sliding bearing 10, the swinging central gear 6 meshes with the free planetary gear 7, and the free planetary The gear 7 is meshed with the swing internal gear 8. There are a central round hole and a plurality of symmetrical round holes on the ...

Abstract

The present invention discloses a gear transmission stepless automatic speed changer. It includes two planetary gear groups, self-locking mechanism and starter clutch. Every planetary gear group is composed of central gear, planetary gear, internal gear and planetary carrier. The central gear is meshed with planetary gear, the planetary gear is meshed with internal gear, the planetary carrier is coupled with gear shaft of planetary gear, and the planetary carriers of two planetary gear groups are formed into one whole body, its self-locking mechanism is mounted between two planetary gear groups.

Description

1. Technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a speed change device on motorized and manpower driven vehicles. 2. Background technology [0002] The mechanical transmission of existing automobiles cannot be automated alone, and fuel oil is wasted when manual operation is improper. Existing hydraulic and electric automatic shifters cannot complete the shifting work alone, and finally require mechanical transmission, which cannot be continuously variable in the whole process. The hydraulic transmission consumes oil, and the oil pressure of the pressure system comes from the engine, which is a reactive power consumption for walking, so it consumes oil. The torque converter of the hydraulic electric transmission cannot change continuously throughout the whole process, and finally depends on automatic shifting to complete. The opening of the gas valve can only be divided according to each gear. Th...
