Embodiment 1

[0034] Such as Figure 1-Figure 5 The torsional vibration-damping adapter of the gear shift system without friction rings shown includes an adapter sleeve 6, a splined hub inner ring 2, a splined hub outer ring 5, a friction plate 7 and a spring set 4; the splined hub inner ring 2. The friction plate 7 and the outer ring of the spline hub 5 are coaxially arranged in sequence, and the web plate 201 of the inner ring of the spline hub and the web face plate 501 of the outer ring of the spline hub are mated and connected so that the inner ring of the spline hub The abdominal plate 201 of the spline hub outer ring and the abdominal plate 501 of the spline hub outer ring are all in close contact with the friction plate 7, and the corresponding positions of the abdominal plate 201 of the spline hub inner ring, the friction plate 7 and the web plate 501 of the spline hub outer ring There are spring windows 10 at each place, the spring group 4 is located in the spring window 10, and b...

Embodiment 2

[0056] This embodiment is the same as embodiment 1 except the following technical features:

[0057] The torsional vibration damping adapter for a gear shift system without a friction ring is suitable for new energy vehicles (such as pure electric vehicles, hybrid vehicles and extended-range electric vehicles) with driving force provided by a motor, and is applied in a gear shifting system.

[0058] Such as Figure 11-Figure 13 As shown, this implementation example is applied to the fixed axis gear shifting mechanism. When the automobile needs to perform a shift operation, the shift fork 9 is moved by an external force, and the shift fork 9 drives the adapter sleeve 6 to move axially. After the adapter sleeve 6 moves to the direction of the outer engagement ring gear for a certain distance, the inner spline teeth of the adapter sleeve 6 contact with the teeth of the outer engagement ring gear 15 to form gear meshing. At the same time, the inner spline teeth of the adapter sle...

Abstract

The invention relates to the technical field of gear shifting of electric vehicles, and discloses a torsional vibration damping adapter for a gear shift system without a friction ring, which includes an adapter sleeve, an inner ring of a splined hub, an outer ring of a splined hub, a friction plate and a spring group; The inner ring of the spline hub, the friction plate and the outer ring of the spline hub are arranged coaxially in sequence, and the web face plate of the inner ring of the spline hub is connected with the web face plate of the outer ring of the spline hub, so that the inner ring of the spline hub The web plate of the spline hub outer ring and the web plate of the spline hub outer ring are all in close contact with the friction plate, and spring windows are opened at the corresponding positions of the web plate of the spline hub inner ring, the friction plate, and the web plate of the spline hub outer ring , the spring set is located in the spring window, and both ends of the spring set are in contact with the web plate of the inner ring of the spline hub, the friction plate and the web plate of the outer ring of the spline hub, and the inner spline of the adapter sleeve The spline teeth are engaged with the external spline teeth of the outer ring of the spline hub. The beneficial effect is that the friction lock ring and other parts are omitted, and the shock vibration generated during the synchronization process of shifting can be reduced.

Description

technical field [0001] The invention relates to the technical field of gear shifting of electric vehicles, in particular to a torsional vibration damping adapter for a gear shift system without a friction ring. Background technique [0002] The research and development of new energy vehicles has received more and more attention from the industry, and installing automatic transmissions on new energy vehicles is gradually considered to be an effective solution to improve power and economy. Among them, automatic mechanical transmission (AMT) is an important option for the transmission system of new energy vehicles due to its simple structure and low cost. [0003] The synchronizer in the AMT is equipped with multiple friction rings to assist gear shifting and eliminate the speed difference between the input end and the output end during the shifting process. In this process, it takes a long time to achieve synchronization, and the speed difference will cause certain The impact...
