System for adjusting shifting force of manual transmission

Abstract

The invention belongs to the field of automobile transmissions and particularly relates to a system for adjusting shifting force of a manual transmission. The system is characterized by being composed of two independent subsystems. One subsystem is a gear shifting execution system which comprises a synchronizer, a gear shifting fork, a fork shaft, a guide block and a gear shifting poking head. The gear shifting execution system is used for specifically executing gear shifting operation of the transmission, and the gear shifting poking head rotates to drive the guide block, the fork shaft and the gear shifting fork to move along the axial direction of the transmission and finally drive the synchronizer to achieve gear shifting. The other subsystem is a shifting force adjusting system which can adjust the shifting force through a replaceable self-locking spring device according to the shifting force, the self-locking spring device is directly fastened on an upper cover through threads, and a self-locking device can be replaced according to different gear shifting force requirements to achieve quick adjustment. The system improves adjusting accuracy and efficiency of the shifting force, improves system working reliability and structure compactness by adopting the shifting force adjusting system which is more scientific and reasonable.

Description

technical field [0001] The invention relates to transmissions, in particular to an adjustment system for shift force of manual transmissions. Background technique [0002] The traditional manual transmission adopts the principle of advanced design in the design of shift force, that is, in the design stage of the transmission, the design requirements of each part of the shift system are determined through calculation and testing, and the transmission is shifted through the dimensions, tolerances, parameters, etc. of each part. force determination. Although this kind of way is convenient to realize the design of shifting force through the design of parts. However, the current customers have higher and higher requirements for transmission shifting performance, and the traditional method of controlling the transmission shifting force is too extensive, and it is impossible to achieve precise control under the premise that the machining accuracy of the existing parts is not high ...

Problems solved by technology

However, the current customers have higher and higher requirements for transmission shifting performance, and the traditional method of controlling the transmission shifting force is too extensive, and it is impossible to achieve precise control under the premise that the machining accuracy of the existing parts is not high enough. Easy to cause cost increase

Therefore, due to the limitations of the design concept and structure, the existing transmission cannot realize precise control and rapid adjustment of the shifting force under the premise of reasonable accuracy and cost requirements, and cannot meet the customer's requirements for shifting performance improvement.
