Abstract
The invention belongs to the technical field of automobile transmissions and relates to an automobile transmission gear locking mechanism, which comprises a shifting housing, wherein a shifting shaft is arranged in the shifting housing; a dual-H valve is mounted outside the shifting housing; a shifting head and a gear locking ring are fixedly mounted on the shifting shaft; a locking pin used cooperatively with the gear locking ring is arranged on the shifting housing; and an interlocking fork sleeves the shifting shaft. The automobile transmission gear locking mechanism has the benefits as follows: the shifting direction is controlled by adjusting the relative positions of the locking pin and the gear locking ring so as to realize locking of different gears, and shifting of an auxiliary box is realized by driving the dual-H valve through the interlocking fork; and in addition, the automobile transmission gear locking mechanism is reliable in design principle, simple in structure, capable of realizing purely-mechanical locking, and reliable in performance, and has extremely wide application prospect.
Description
Technical field
The invention belongs to automotive transmission technical field, relate to a kind of automotive transmission, particularly relate to a kind of automotive transmission shift-lock locking mechanism.
Background technique
Automotive transmission is the speed change gear of the actual travel speed of a set of rotating speed for coordinating motor and wheel, for playing the optimum performance of motor.Speed changer in vehicle traveling process, can produce different gear ratio between motor and wheel, can make engine operation under the power performance state of its best by gearshift.
The speed changer of heavy-duty car and some automobile coupling is the many gear speed transmissions with odd-side, if the control of speed changer adopts two H manipulation type, then need in design to realize odd-side when high gear and low gear, the gear of main tank is different, this just needs the needs when odd-side is in high gear that some gear of main tank is carried out locking, and needs some gear other of main tank to carry out locking when odd-side is in low gear.
Summary of the invention
The object of the invention is to, for the defect that above-mentioned prior art exists, provide design a kind of automotive transmission shift-lock locking mechanism.
For achieving the above object, following technological scheme is provided:
A kind of automotive transmission shift-lock locking mechanism, comprising: gearshift housing, and be provided with shifting shaft in described gearshift housing, described gearshift housing is provided with double H valve and fitting seat; It is characterized in that: described shifting shaft is installed with gearshift head and shift-lock stop ring, be provided with in described fitting seat with shift-lock stop ring with the use of lock pin, on described shifting shaft, cover has interlock fork.
Preferably, described interlock fork is located at gearshift head both sides.
Preferably, described lock pin is the cylinder with hemisphere plush copper.
Beneficial effect of the present invention is, is controlled the restriction in gearshift direction, thus realize the locking of different gear by the relative position adjusting lock pin and shift-lock stop ring, and drives double H valve to realize the gearshift of odd-side by interlock fork; In addition, design principle of the present invention is reliable, and structure is simple, and pure mechanical locking, reliable performance, has application prospect widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of automotive transmission shift-lock locking mechanism embodiment provided by the invention.
Wherein, 1-shifts gears housing, 2-interlock fork, and 3-shifts gears head, 4-shifting shaft, 5-shift-lock stop ring, 6-gear-shifting rocker arm, 7-lock pin, 8-double H valve, 11-fitting seat.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the present invention will be described in detail, and following examples are explanation of the invention, and the present invention is not limited to following examples.
Fig. 1 shows a kind of automotive transmission shift-lock locking mechanism provided by the invention, comprise: gearshift housing 1, shifting shaft 4 is provided with in described gearshift housing 1, described gearshift housing 1 is provided with double H valve 8 and fitting seat 11, described shifting shaft 4 is installed with gearshift 3 and shift-lock stop ring 5, described gearshift housing 1 is provided with fitting seat 11, lock pin 7 is installed in fitting seat 11, described lock pin 7 and shift-lock stop ring 5 with the use of, in order to limit the sense of rotation of shift-lock stop ring 5, on described shifting shaft 4, cover has interlock fork 2, described interlock fork 2 is connected to the both sides of gearshift 3, shifting shaft 4 is connected with gear-shifting rocker arm 6, realize moving axially of shifting shaft 4 by gear-shifting rocker arm 6 and rotate.
In the present embodiment, interlock fork 2 can move with the axis of shifting shaft 4, double H valve 8 can be driven to realize the gearshift of odd-side by the movement of interlock fork 2.
In the present embodiment, lock pin 7 is the cylinder with hemisphere plush copper.
In the present embodiment, gearshift 3 and shift-lock stop ring 5 can move axially with shifting shaft 4 and rotate, the sense of rotation of shift-lock stop ring 5 is limited by lock pin 7, adjust the relative position of lock pin 7 and shift-lock stop ring 5 as required, thus the sense of rotation of restriction shift-lock stop ring 5, thus realize the locking of different gear.
The preferred embodiment of the present invention is only above; but the present invention is not limited thereto; any those skilled in the art is thinkable does not have creationary change, and some improvements and modifications done without departing from the principles of the present invention, all should drop in protection scope of the present invention.
