Technical field

It is that a kind of be mounted on assists carrying out semi-automatic shift gears on manual transmission the present invention relates to automotive transmission field Secondary gear.

Background technique

Domestic either heavy truck, middle card, light truck or micro- face microcaloire now, all use the mechanical transmission of manual shift, Although this speed changer has many advantages, such as that of simple structure and low cost, easy to maintenance and transmission efficiency is high, when due to gear shift Need to step on clutch pedal and be just able to achieve gear shift, vehicle heavy duty, traffic congestion and urban congestion operating condition when driving, frequently use from Clutch not only will increase driver behavior intensity while be also easy to lead to clutch premature wear, increase the use and maintenance of vehicle at This, this is that existing armstrong's patent speed change self structure is unavoidable.In addition, vehicle is light when due to vehicle zero load, full load vehicle Weight, it is of poor quality it is bigger, overload when it is even more serious, cause to be difficult to take into account when speed changer and Engine Matching, the power of engine Property and economy are difficult to be not fully exerted.

Also because it is shifted gears, difficulty makes new hand's study get up to be difficult to manual gear car, and needing to practice for a long time could be ripe Practice shift.

Summary of the invention

The technical problems to be solved by the present invention are: for manual gear gearbox shifting it is cumbersome, to clutch abrasion The problems such as serious, provides a kind of secondary speed changing structure, is installed in manual transmission and semi-automatic shift gears may be implemented.

The present invention adopts the following technical solutions:

A kind of semi-automatic shift gears, which rise, turns round secondary gear, including input shaft and output shaft, has driving tooth and jackshaft on input shaft Driven tooth engagement, the driven tooth engagement of jackshaft driving tooth and output shaft of jackshaft, output shaft driven tooth be mounted on unidirectionally from On the outer ring of clutch, low-grade unidirectional one-way clutch inner ring is mounted on output shaft.

Shift tooth hub is installed on output shaft, has low-grade conjunction gear on the inside of output shaft driven tooth, is cased with and changes on tooth hub of shifting gears Shelves tooth set, the position of moving gear shift tooth set can control whether shift tooth hub couples low-grade conjunction gear.

Output shaft and input shaft are coaxially arranged, and active flank has direct high conjunction gear, can by the position of shift tooth set Whether couple direct high conjunction gear with control shift tooth hub.

Driving tooth is located at input shaft end, driving tooth axial aperture, and output shaft insertion driving tooth center simultaneously realizes that sliding is matched It closes.

Driving tooth is coupled by direct high one-way clutch and direct high conjunction gear.

Direct high one-way clutch is mounted in driving tooth inner hole, and outer ring and driving tooth rotate synchronously, and direct high is unidirectional Clutch inner ring is connected with direct high conjunction gear, and the two sky is set on the output shaft.

Input shaft and output shaft pass through two bearings fixed installation positions, a bearing and input shaft cooperation, another axis It holds and cooperates with output shaft.

Secondary gear is mounted on basic transmission side, and the position of shift tooth set is controlled by electric gear shifting mechanism, is passed through Manual gear shift mechanism controls basic transmission.This pair gear and firmly speed changer is used cooperatively, output shaft are defeated by its end Shaft driving tooth transfers power to basic transmission, and output shaft max. output torque is less than or equal to what basic transmission can bear Maximum input torque.

Beneficial effects of the present invention:

The present invention meets traffic safety code, when vehicle driving needs, and can reliably be assisted using the frictional work of engine Control for brake speed, to guarantee driving safety, while the matching between engine and speed changer can also be optimized, allow engine Performance is more fully played, to improve the power performance and the economy performance of vehicle；Traditional driving can also be changed Mode, the labor intensity for mitigating motorist, in normally travel, shift no longer needs stepping on clutch, and it is difficult to greatly reduce operation Degree；The service life of clutch can significantly be extended, save the use and maintenance expense of automobile；

Have no need to change original manual basic transmission structure, it is only necessary to cut basic transmission shell, this pair is installed in insertion The repacking to existing manual gear gearbox can be completed in transmission mechanism.The configuration of the present invention is simple, it is low in cost, manufacture be easy, Easy to maintenance, particularly suitable China's actual conditions, have biggish social effect and economic significance, are worthy of popularization.
