Abstract
A pneumatic gearshift for car auxiliary speed variator relates to gearshift for car auxiliary speed variator. With simple structure and retaining mechanical gearshift control mechanism of main speed variator while adopting pneumatic (or hydraulic) gearshift control mechanism for auxiliary speed variator, the utility model is provided to overcome the disadvantages of complex internal structure and inconvenient operation of existing motor vehicle caused by separate steering of main and auxiliary speed variators. The pneumatic gearshift adopts the following technical proposal: the inner shaft hole of an upper cover 6 is provided with a shifting fork shaft 9; one end of the shifting fork shaft 9 is provided with a shifting fork, while the other end with a piston 11 having a sealing fitting 10 and arranged inside a cylinder body 12.
Description
One, technical field
The utility model relates to automobile demultiplicator gearshift, especially automobile demultiplicator Pneumatic shift mechanism.
Two, background technology
The general-utility car change-speed box gear that advances is generally fourth gear or five grades, under the situation such as poor at pavement conditions, that the gradient is bigger, usually can not satisfy use, increase two-speed transmission in its front (or back) for this reason, traditionally two-speed transmission is called demultiplicator, fourth gear or more than five grades change-speed box be called main gearbox.Because major and minor change-speed box, therefore has two cover mechanical control mechanisms for handling respectively in automobile, that the inner structure that exists automobile is deployed is numerous and diverse, the equal inconvenience of the manipulation in using.Number of patent application 88203815.X discloses " a kind of automobile variable speed steering unit " and has still had above-mentioned weak point.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, the mechanical gear shift steering unit that keeps main gearbox, the gearshift of demultiplicator is moved by cylinder (hydraulic actuating cylinder) by pressurized air (or liquid), the automobile demultiplicator Pneumatic shift mechanism that realizes different gear meshing.
The technical scheme that the purpose of this utility model adopted is, an end face that includes loam cake is equipped with the cylinder body that casing wall has two connecting bores, the other end bolt together of cylinder body has seal cover cap, axis hole is equipped with declutch shift shaft in its loam cake, and declutch shift shaft is equipped with shift fork, the other end is equipped with the piston that is placed on the sealing member that has in the cylinder body.
The utility model, declutch shift shaft is with the fixing shift fork of stop screw.
The utility model is assemblied on the demultiplicator, shift fork fork is in demultiplicator on the cliding gear, two connecting bores connect source of the gas (or hydraulic power source) respectively on the cylinder wall, when gas (or liquid) enters cylinder body from a connecting bore, promote piston and the parallel mobile shift fork of declutch shift shaft, shift fork drives cliding gear in the demultiplicator again, to reach speed change; Otherwise gas (or liquid) enters cylinder body from another connecting bore, promotes the parallel mobile shift fork of piston and declutch shift shaft on the contrary, and shift fork drives cliding gear in the demultiplicator again, changes speed again.The utility model is simple and compact for structure, and fabrication and installation are easy to maintenance, and manoeuvrable can effectively enlarge operator's compartment inner area, characteristics such as elegant in appearance.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is an embodiment sectional structure of a utility model scheme drawing.
Among the figure: 1-screw 2-spring 3-steel ball 4-oil sealing cap 5-bolt 6-loam cake 7-stop screw 8-shift fork 9-declutch shift shaft 10-sealing member 11-piston 12-cylinder body 13-seal cover cap 14-connecting bore
Five, the specific embodiment
As shown in drawings, axis hole is equipped with declutch shift shaft 9 in the loam cake 6, one end of declutch shift shaft 9 has two arc grooves, middle part, and fixedly shift fork 8, the other end are equipped with the piston 11 of being with sealing member 10 with stop screw 7, be equipped with screw 1, spring 2, steel ball 3 in the loam cake 6 lower end cinclides, loam cake 6 outer walls are equipped with the cylinder body that connecting bore 14 is arranged 12 that oil sealing cap 4, another outer wall are equipped with closure 13 with bolt 5.
Claims (2)
1, a kind of automobile demultiplicator Pneumatic shift mechanism, an end face that includes loam cake (6) is equipped with the cylinder body (12) that casing wall has two connecting bores (14), the other end of cylinder body (12) is connected with seal cover cap (13) with bolt (5), it is characterized in that the interior axis hole of loam cake (6) is equipped with declutch shift shaft (9), declutch shift shaft (9) is equipped with shift fork (8), the other end is equipped with the piston that sealing member (10) are arranged (11) that is placed in the cylinder body (12).
