Abstract

The invention relates to a synchronizer assembly for a truck and a machining technology thereof, and belongs to the technical field of truck synchronizer and machining thereof. The synchronizer assembly comprises a gear sleeve and a gear core. The gear core is embedded in the gear sleeve, and the gear core and the gear sleeve are fixed and limited through a limiting device. The limiting device iscomposed of a sliding block, a sliding block mounting groove and an elastic element, and the sliding block is installed in the sliding block mounting groove through the elastic element. The sliding block mounting groove is formed in the gear sleeve. Gear teeth matched with the sliding block mounting groove are arranged on the outer surface of the sliding block. The machining technology comprises the following steps that the gear sleeve and the gear core are subjected to the processes such as normalizing, rough turning, finishing turning, gear hobbing, gear shaping and anti-rust oil applying, then are subjected to carburizing heat treatment, and then are subjected to polishing, ultrasonic cleaning, assembling, anti-rust oil applying and packaging, and a finished product is obtained. The prepared synchronizer assembly has the advantages that synchronize axial movement is not prone to occurring, the service life is long, abrasion is not prone to occurring, and the strength is high.

Description

technical field [0001] The invention relates to the technical field of a truck synchronizer and its processing, in particular to a truck synchronizer assembly and its processing technology. Background technique [0002] The gear shifting of the old-fashioned transmission adopts the "two-leg clutch" method. The upshift stays in the neutral position for a while, but the clutch needs to be lifted up. The purpose is to synchronize the clutch plate with the flywheel, and the speed must be the same to be able to shift smoothly. , If the gear shift is slow and the speed drops to idle speed, it cannot be engaged. When downshifting, the throttle should be in the neutral position, and the clutch should be kept lifted at the same time to reduce the speed difference between the gears. But this operation is more complicated and difficult to master accurately. Therefore, the designer created a "synchronizer", through which the gears to be meshed can reach a consistent speed and mesh smoo...
