Abstract
The invention specifically discloses a transmission fork shaft base control mechanism which solves the problems that an existing transmission control mechanism is low in efficiency, not clear in hand feeling and heavy in gear shifting. Four fork shafts penetrate through a fork shaft base. Three spherical face self-locking grooves axially distributed are formed in the lower column face of each fork shaft. A strip-shaped self-locking hole is formed in the portion, below the spherical face self-locking groove in the middle, of each fork shaft base. A self-locking spring is arranged in each strip-shaped self-locking hole. A self-locking steel ball is placed on each self-locking spring. A spherical face interlocking groove is formed in the right column face of each fork shaft. An interlocking through hole is formed in the fork shaft base. A pair of interlocking steel balls are placed in the portion, between every two adjacent fork shafts, of the interlocking through hole. An interlocking steel ball and an idle gear switch locking pin are arranged in the portion, on the right side of the fork shaft at the right end, of the interlocking through hole. An interlocking cylindrical pin penetrates through the portion, between the interlocking steel balls, of each fork shaft. By means of the transmission fork shaft base control mechanism, the hand feeling is clear in the whole gear selecting and shifting process, the gear shifting operation is smooth, and self-locking and interlocking of gear shifting are achieved at the same time.
Description
Technical field
The present invention relates to automobile handle structure, be specially a kind of speed changer fork shaft seat operating mechanism.
Background technique
In recent years, along with the develop rapidly of automotive engineering, market is to automobile, and especially the requirement of commercial car manoeuvring performance is more and more higher.Along with commercial car adopts flexible shaft manipulation in a large number, gearbox operating mechanism becomes the important step affecting car load manoeuvring performance.
But conventional gearbox operating mechanism inefficiency, feel is unintelligible and gear shift is heavy, can not meet the need of market.
Summary of the invention
There is the unintelligible and problem that gear shift is heavy of inefficiency, feel to solve existing transmission control in the present invention, provides a kind of speed changer fork shaft seat operating mechanism.
The present invention adopts following technological scheme to realize: speed changer fork shaft seat operating mechanism, comprises fork shaft seat, places and be parallel to each other four fork shafts before and after fork shaft seat is installed with; The lower cylinder of every root fork shaft is all arranged three sphere self-locking grooves of axial distribution, and the fork shaft seat be positioned at below middle sphere self-locking groove is provided with strip self-locking hole, be placed with self-locking spring in strip self-locking hole, self-locking spring be placed with the self-locking steel ball with sphere self-locking groove fit; The right cylinder of every root fork shaft is provided with the sphere interlock recess corresponding with middle sphere self-locking groove location, the interlocking through hole with four sphere interlock recess place axis coaxles is provided with in fork shaft seat, a pair interlocking steel ball is all placed with in interlocking through hole between adjacent two fork shafts, and the neutral switch lock pin being provided with an interlocking steel ball in interlocking through hole on the right side of right-hand member fork shaft and being positioned on the right side of this interlocking steel ball, adjacent two between interlocking steel ball and right-hand member interlocking steel ball and be all installed with interlocking straight pin in being adjacent between a pair interlocking steel ball fork shaft.
During operation, the self-locking steel ball in fork shaft seat strip self-locking hole is pressed into the sphere self-locking groove on certain root fork shaft during by self-locking spring, declutch shift shaft can not move axially voluntarily, can realize the auto-lock process of fork shaft at certain gear, prevent out of supply; When arbitrary fork shaft hangs up certain gear, the cumulative size of often pair of interlocking steel ball is greater than the distance between two fork shafts, interlocking steel ball is under the acting in conjunction of neutral switch lock pin with interlocking straight pin, other three fork shafts are made all to be locked at the neutral position of oneself, prevent from changing to different gears simultaneously, achieve the interlocking of mechanism, overcome existing transmission control and there is the unintelligible and problem that gear shift is heavy of inefficiency, feel.
Reasonable in design of the present invention is reliable, make wholely to select feel in gearshift procedure clear, and gear-change operation is smooth and easy, and achieves self-locking and the interlocking of gear shift simultaneously, prevent because misoperation causes the problem of transmission failure, there is simple, the easy to process and advantage that cost is low of structure.
