Description
Technical field
The present invention relates to truck transmission technology, more particularly to a kind of hybrid transmission control mechanism.
Background technology
The transmission control of usual truck is divided into 3 kinds, is mechanical handling rod-type, flexible shaft manipulation rod-type and automatic respectively
Control type (AMT, AT).It is mostly mechanical handling rod-type and flexible shaft manipulation bar currently on the market in view of cost and technical maturity
Formula.It is apparent to transmit power compared to flexible shaft manipulation mechanical handling bar, is mechanically operated by the use reliability higher of bar, by service life and
Inside even from weather is smaller, and use scope is broader, especially the more severe place of environment industrial and mineral；It is mechanically operated by bar after-sales service
At low cost, after-sales service facilitates simple and direct, and use cost and maintenance cost are well below flexible shaft manipulation rod-type.But with gas in recent years
Bellows cab mounting is popularized, and driver's cabin suspends for 4 air bags, and when being impacted by bumpy road, driver's cabin is integrally beated
Amplitude is larger, speed changer easily occurs and loses rank problem, each heavy truck enterprise tries every means and prevent from losing rank, take effect little.
This patent can thoroughly solve the mechanical lever-type of four point suspension driver's cabins matching, and what bumpy road occurred excessively gear problem.
The structure of the existing mechanical handling rod-type in market is all similar, for the current problem without directly effectively
Measure, be mainly reflected in following several respects:
1st, match four point suspension cab mountings, when meet jolt road conditions when, easily lose rank.
2nd, Current mechanical formula control stick falls gear problem, but increase by increasing transmission shift fork shaft snap rigidity improvement speed changer
Big snap rigidity causes shift of transmission power big, and gearshift is difficult, and driver is also easy to produce feeling of fatigue.
3rd, existing machinery transmission mechanism cannot meet the rapid heavy truck industry of current development, comfort and behaviour in vehicle
Incompatible in vertical property, the satisfaction of user is relatively low.
Invention content
The purpose of the present invention is releasing a kind of hybrid transmission control mechanism, for solving above-mentioned problem of the prior art.

The structure diagram of clutch and gas bomb is shown, as shown in Figure 4 and Figure 5, snorkel 11 is by pressure limiting valve 12 to cylinder
1 mouthful of 10 supplies always, and compressed air is reduced to 5bar by pressure limiting valve.Ejecting rod of cylinder 24 withstands connecting rod 17 and sliding block 18 not at this time
It opposite can slide, i.e., locked gear.When clutch pedal reaches servo point, 1 mouthful of cylinder 10 starts to supply, and air pressure is
10bar.Since two intracavitary of cylinder is there are pressure difference, ejecting rod of cylinder 24 retreats the pressure released to connecting rod 17.Connecting rod 17 and cunning at this time
Block 18 opposite can slide, that is, release locked gear.After stepping on clutch 1, servo-cylinder 4 controls tracheae 7 to ventilate to by pipe 8, to
The mouth 2 of cylinder 10 supplies 10bar gas.Shifting of transmission rocking arm 21 and pull rod 20 is driven to act by connecting rod 17, complete gear shift.
The clutch actuating gas supply point of the present invention is after clutch separation point, it can be ensured that clutch just can be with after being kept completely separate
Gear shift.Ejecting rod of cylinder needs specially treated, it is ensured that the frictional force that gear locks is sufficiently large with locked gear.It is ensured that pressure limiting valve is reliable
Property, in order to avoid do not release gear lock-up condition.When engine misses gear is not in neutral position, gear locks cylinder using double
Circuit controls, it can be ensured that vehicle do not have air pressure it is relatively low when can equally release the locked of gear.
The present invention goes to jointly control the realization of speed-changer operation system from completely new angle, has abandoned original design concept,
The strategy controlled in itself by transmission control has been abandoned, theory combination driver's manipulation of physical is controlled with completely new auxiliary
Feature realizes multi-mode, multilogic accurate control mode for the first time.The present invention thoroughly solves changing for mechanical speed change operating mechanism
The problem of gear power is big, 4 air bag suspension driver's cabins are lost rank controls theory and cleverly overall structural arrangement with completely new mixing,
The matching a variety of models that mechanical transmission operating mechanism is made to have nothing to fear.Additional cost of the present invention is relatively low, with minimum cost, solution
The greatest problem of mechanical transmission handle structure of having determined development.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
