Lock ring type inertia synchronizer

Abstract

The invention discloses a lock ring type inertia synchronizer, which comprises a tooth hub (1), a shift ring (3) and a sliding toothed sleeve (2), wherein a plurality of standard involute splines are formed at the position of an inner hole of the tooth hub (1) and matched with a transmission secondary shaft (6); on one end face of the tooth hub (1), the shift ring (3) is divided into three equal parts and pressed by a rivet, and the shift ring (3) is riveted on the end face of the tooth hub (1) by the rivet to form a tooth hub assembly together with the tooth hub (1); a shift fork groove (4) is formed on the external circle of the sliding toothed sleeve (2), and oil storage tanks (5) are arranged on the two sides of the bottom diameter of the shift fork groove (4); and a plurality of standard invoute splines are formed in the sliding toothed sleeve (2), the two ends of each spline are provided with fastening negative cones, and an inclined angle is formed from the two end faces to theposition of a reverse Y-shaped corner of each spline in the sliding toothed sleeve (2). The lock ring type inertia synchronizer shifts gears according to the requirements of a forward gear used by anengineering mechanical vehicle, can shift conveniently, shortens synchronization time and can reversely use the sliding toothed gear in a certain wear range.

Description

technical field [0001] The invention relates to a lock ring type inertia synchronizer, which is a gearbox synchronizer for engineering machinery vehicles. Background technique [0002] Gearboxes for construction machinery vehicles usually use gear pairs to directly shift gears, resulting in large shifting torque and high noise. At present, some types of gearboxes of construction machinery vehicles also use lock-ring inertia synchronizers to shift gears. Since construction machinery vehicles generally have fewer forward gears, especially when the load is slow, the shift force and synchronization time Improvement is a key item to improve the overall performance of the gearbox. Contents of the invention [0003] The invention provides a lock ring type inertial synchronizer, which is one-way gear shifting according to the requirements of forward gears for engineering machinery vehicles, and is designed directionally to achieve the expected goals of easy gear shifting and obvi...
