An inertial synchronizer assembly

Abstract

The invention discloses an inertia synchronizer assembly. It includes a sliding gear sleeve, a synchronizing ring, a combined gear ring, and a spring leaf and a steel ball. The sliding gear sleeve is provided with a spherical mounting hole, and the outer ring of the synchronizing ring is provided with a slope boss. The steel ball is located on the In the space enclosed by the spherical mounting hole and the slope boss, one side of the spring piece is fixed on the sliding tooth sleeve and the steel ball is limited. The present invention adopts the spring sheet + steel ball combination to replace the push block (support column) + spring combination, and cooperates with the sliding tooth sleeve and other parts to complete the pre-synchronization work. Compared with the existing scheme, the pre-synchronization structure can be used for Synchronizers, such as sub-box synchronizers.

Description

technical field [0001] The invention belongs to the technical field of transmission variable speed walking system, and in particular relates to an inertia synchronizer assembly. Background technique [0002] Existing heavy-duty gearbox main box synchronizer assembly mostly adopts the structure of gear seat, gear sleeve, combined gear ring, synchronous ring, spring, and push block (supporting post). The pre-synchronization schemes all adopt the structure of spring and push block (support column). In the prior art scheme, the combination of 3-4 sets of springs and push blocks (push block) plays the role of pre-synchronization, which has many types and quantities of parts, high cost and difficult assembly. [0003] Specifically, existing synchronizer schemes such as figure 1 As shown, it is composed of sliding gear sleeve 1, push block (support column) 2, synchronous ring outer ring 3, synchronous ring intermediate ring 4, spring 5, synchronous ring inner ring 6, combined gea...

AI Technical Summary

Problems solved by technology

There are usually 3-4 sets of push blocks (support columns) + spring 5 combinations in a synchronizer assembly (combined figure 2 , image 3 As shown), the combination must be arranged on the tooth seat, and cannot be used on the structure without tooth seat (mostly used in the rear sub-box). The existing heavy-duty box rear sub-synchronizer structure, due to space constraints, usually does not use the tooth seat structure. This makes the conventional post + spring pre-synchronization structure installed without position

And it is necessary to set the middle push block 9 to center, (when in neutral, ensure that the sliding gear sleeve is in the middle position), there are usually 2 sets of middle push blocks, the number is large, and the cost is high
