Problems solved by technology

[0002] At present, the spline meshing teeth of the symmetrical structure of the lock-ring synchronizer have the problem of secondary impact of shifting, that is, when the synchronization of the synchronizer ends and the sliding sleeve meshes with the combined ring gear, an excessive shifting impact will be generated, which is reflected on the transmission. The gears feel unsmooth such as frustration and stagnation, which reduces the comfort of shifting and increases the driver's driving intensity and fatigue
Moreover, the large secondary impact of the lock ring synchronizer will generate noise, which will affect the overall performance of the transmission

Embodiment Construction

[0035] The present invention is described in further detail below in conjunction with accompanying drawing:

[0036] see figure 1 and figure 2 , the present invention includes a gear hub 5 sleeved on the main shaft of the transmission, a sliding sleeve 6 is sleeved on the gear hub 5, and a coupling ring gear 4 is arranged on both sides of the sliding sleeve 6; between the sliding sleeve 6 and the coupling gear 4 Set with synchronous ring; such as Figure 8 and Figure 9 As shown, the synchronous ring includes an inner friction ring 3 , a friction intermediate ring 2 and an outer friction ring 1 arranged sequentially from the inside and the outside. Such as image 3 , Figure 4 and Figure 5 As shown, the sliding sleeve 6, the combined ring gear 4 and the spline meshing teeth on the synchronous ring are all asymmetric structures. The inner side of the sliding sleeve 6 is provided with a slider 7, and a spring 9 is arranged between the sliding sleeve 6 and the gear hub 5...

Abstract

The invention discloses a locking ring type synchronizer with dissymmetric spline meshing teeth. The locking ring type synchronizer comprises a gear hub sleeving a transmission spindle, a slide bushing sleeves the gear hub, and combination tooth rings are arranged on two sides of the slide bushings respectively; a synchronization ring is arranged between each combination tooth ring and the slide bushing; the spline meshing teeth on the slide bushing, the combination tooth rings and the synchronization rings are all in dissymmetric structures. Since the spline meshing teeth on the slide bushing, the combination tooth rings and the synchronization rings are designed in the dissymmetric structures, the synchronizer is better in locking reliability, locking faces of the slide bushing and the synchronization rings are long in meshing time and large in combination area, and a favorable locking structure foundation is provided for a synchronization process; owing to the spline meshing teeth in the dissymmetric structures, sliding distance of the slide bushing on locking faces of the synchronization rings is increased, shifting speed difference caused by idle stroke generated when the slide bushing moves close to the combination tooth rings is reduced, large shifting speed difference results in impact of shifting, and accordingly secondary shifting impact after synchronization is alleviated.

Description

technical field [0001] The invention belongs to the technical field of synchronizers, and relates to a lock ring type synchronizer, in particular to a lock ring type synchronizer with asymmetrical spline meshing teeth. Background technique [0002] At present, the spline meshing teeth of the symmetrical structure of the lock-ring synchronizer have the problem of secondary impact of shifting, that is, when the synchronization of the synchronizer ends and the sliding sleeve meshes with the combined ring gear, an excessive shifting impact will be generated, which is reflected on the transmission. The gears have unsmooth feeling such as frustration and stagnation, which reduces the comfort of shifting, increases the intensity of driver's driving and easily fatigues. Moreover, the large secondary impact of the lock ring synchronizer will generate noise, which will affect the overall performance of the transmission. Contents of the invention [0003] The purpose of the present ...
