Problems solved by technology

In the first edition of "Automobile Manual Transmission and Transaxle" published by Machinery Industry Press in August 1998, it was mentioned that because there is no reverse gear synchronization process, gear teeth often occur when the reverse gear is engaged, which seriously affects the service life of the gear
Because the car is parked when it is in reverse gear, but the main shaft is still rotating, and the reverse intermediate gear is a spur gear, which is easy to produce tooth beating when it slides in and meshes with the reverse gear on the main shaft.

Embodiment Construction

[0020] Before describing in detail, it should be noted that the "fixed" in the specification of the present invention, unless otherwise specified, means that it can be connected by various well-known means, such as screw connection or riveting. , Welding, card slot type, embedded, etc. to achieve.

[0021] As shown in Figures 1 to 5, the reverse gear synchronization mechanism of the present invention includes a reverse gear sleeve 2, a reverse gear shift fork 13 fixed on a fork shaft 12, and a conical ring 3 mounted on the main shaft 1. And the synchronization ring 4, the main shaft 1 is provided with a bearing 8, the inner ring of the bearing 8 is fixed on the main shaft 1, and the outer ring is fixed on the rear case of the transmission; the fixed pitch teeth 9 are fixed on the main shaft, and the tapered ring 3 It is sleeved on the fixed pitch teeth 9 and fixedly connected with the rear box body to be installed (that is, fixed connection). There is a clearance fit between the t...

Abstract

A synchronizing mechanism for the reverse-gear shift or car is composed of a mainshaft, a reverse-gear shift synchronizing toothed sleeve installed radially onto mainshaft, a conic ring sleeving on mainshift in movable mode and fixed to box body, and a synchronizing ring sleeving on said conic ring in movable mode, fixed to mainshaft, and with radial tooth engaged with said toothed sleeve and synchronizng spring at the root of said radial tooth.

Description

【Technical Field】 [0001] The invention relates to an automobile reverse gear synchronization mechanism, in particular to an automobile reverse gear shift synchronization mechanism. 【Background technique】 [0002] The transmission is a gear system that transfers the engine power to the wheels of the car. When the transmission is combined with the clutch, the transmission receives the torque from the engine through the input shaft, and then the torque is transmitted through a set of gears, either increased or directly transmitted, and the final torque is generated to drive the output shaft of the transmission that is indirectly connected to the driving wheels to rotate ; Transmission has two main functions, selects different speed ratios according to various conditions, and provides a way to reverse the movement of the car. [0003] Synchronous meshing transmission is equipped with a synchronizer, which can control the speed of shafts and gears before combining. The main function o...
