Problems solved by technology

[0002] There are two types of speed change methods for existing vehicle transmissions: one is a transmission without a synchronizer, which has a simple structure, but requires skilled operation when shifting gears, slow speed change, and easily produces inter-tooth impact and noise; the other is a transmission with a synchronizer. Although the transmission solves the shortcomings of the transmission without synchronizer, it has the disadvantages of complex structure, high manufacturing process requirements, large space occupied between shafts, and easy wear and tear of friction elements during use.
The shortcoming and deficiency of above-mentioned two kinds of speed changers bring certain inconvenience and unfavorable to manufacturer and user

Embodiment Construction

[0009] Such as figure 1 , 2 The non-impact variable speed transmission gear shown is composed of gear ring 1 and hub 2; gear ring 1 and hub 2 are connected by an interlocking constant mesh mechanism through the elastic gap, and gear ring 1 and hub 2 pass through splint 5 and splint 6 with screws 7 is connected as an axial limit, and splints 5 and 6 are fixed on the gear ring 1.

[0010] The jaw-type constant meshing mechanism of the elastic gap is specifically: the jaw-type constant meshing mechanism of the elastic gap is specifically: an meshing gap is provided between the meshing teeth connected between the ring gear 1 and the hub 2, and the unilateral clearance angle is α, using elastic elements to make the meshing teeth on the hub in the middle of the gap under the condition of no torque transmission, forming an elastic gap structure. Such as figure 2 As shown, the elastic element is a leaf spring 3, and the leaf spring 3 is connected to the ring gear 1 through a screw...

Abstract

The invention discloses a non-impact speed-change transmission gear wheel, which is formed by a tooth ring and a rim. Wherein, the tooth ring and the rim are connected via the tooth-embedded mesh device with flexible space; the tooth ring and the rim are axially limited via the clamp plates; the clamp plates are fixed on the tooth ring; said tooth-embedded mesh device comprises: mesh space between the mesh tooth that connecting the tooth ring and the rim; the flexible element can make the mesh tooth of rim at the middle of space while do not transmit torque to form a flexible space; the inner hole of rim is a inner-pattern key or a smooth hole with key groove. The invention has simple structure, which can avoid the lower shift speed, the impact and noise when meshing the gear wheels, while it can be used in duplicate gear or single gear wheel, or different speed changers.

Description

technical field [0001] The invention relates to a non-impact speed change transmission gear that can be directly meshed and shifted. Background technique [0002] There are two kinds of speed change methods in existing vehicle transmissions: one is a transmission without a synchronizer, which has a simple structure, but requires skilled operation when shifting gears, slow speed change, and easily produces inter-tooth impact and noise; the other is a transmission with a synchronizer. Although the transmission solves the shortcomings of the transmission without a synchronizer, it has complex structures, high manufacturing process requirements, a large space occupied by the shafts, and the friction elements are easy to wear during use. The shortcoming and deficiency of above-mentioned two kinds of speed changers bring certain inconvenience and disadvantage to manufacturing enterprises and users. Contents of the invention [0003] Aiming at the shortcomings of the existing tr...
