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
The present invention relates to transmission-like, specifically is a kind of regulating system for manual transmission gearshift power.
Background technique
Traditional manual transmission is taked design principle in advance in design gearshift power, namely the transmission design stage just by calculating and the designing requirement of each part of shifting system is determined in test, the size by each part, tolerance, parameter etc. realize determining shift of transmission power.Though this kind mode be convenient to by the design to part realize to the gearshift power design.But, current client is more and more higher to the shift of transmission performance requirement, with traditional method shift of transmission power is controlled too extensively, under the not high enough prerequisite of existing part processing precision, can't be realized accurate control, increase the rising that element precision then causes cost easily.So existing speed changer can't satisfy the client to the requirement of gearshift performance boost because the restriction of design concept and structure can't realize accurate control and quick adjustment to gearshift power under the prerequisite of reasonable accuracy and cost requirement.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide that a kind of design concept is more advanced, more reasonable structure, cost is lower, efficient is higher a kind of can the replacing fast, realize the regulating system that is used for manual transmission gearshift power to the accurate adjusting of gearshift power.
The present invention is achieved through the following technical solutions:
A kind of regulating system for manual transmission gearshift power of the present invention, it is characterized in that: regulating system is made up of two independent subsystem, one is the gearshift executive system, this subtense angle comprises synchronizer, selector fork, fork shaft, guide block, gearshift shifting block, be responsible for the concrete execution of shift of transmission operation, rotate by the gearshift shifting block, moved axially along speed changer by gearshift shifting block drive guide block, fork shaft, selector fork, finally drive synchronizer and realize gearshift; Another is the gearshift draught control system, this system is according to the size of gearshift power, realize the adjusting of gearshift power by the self-locking spring device that can change, the self-locking spring device is directly covering by screw threads for fastening, the self-locking spring device is changed in requirement according to different gearshift power, realizes regulating fast.
The present invention compared with prior art by adjusting design concept, improves the gearshift design, adopt a kind of self-locking spring device that can change to regulate self-locking spring power by the gearshift power to different speed changers, realization increases gearshift and sucks sense the accurate adjusting of gearshift power, improves the gearshift performance.Concrete outstanding behaviours exists:
1, the gearshift performance requirement that employing gearshift draught control system can be different to speed changer, do not increasing under the prerequisites such as Element Design precision, manufacture cost, on the basis of original gearshift, regulating by the structural design and the mounting type that change the self-locking spring device.
2, adopt the gearshift draught control system to require to realize regulating fast according to different gearbox shifting power.Because self-locking device is fastened on by modes such as screw threads and covers, the standardization by to binding thread, self-locking device design realizes the quick replacing of different self-locking spring devices.
3, adopt the gearshift draught control system under the prerequisite of adjusting the design of fork shaft self-locking grooves, to improve the gearshift feel of speed changer, increase gearshift and suck designs such as sense, thereby the gearshift that can simplify prior art sucks the sense design, realize the unified design of multi-functional requirement.
The present invention has improved degree of regulation and the efficient of gearshift power owing to adopted more scientific and reasonable gearshift draught control system, realizes quick adjustment and the multi-functional design of will seeking unification, and strengthens the reliability of system works and the compact type of structure.
