Abstract
The invention discloses an auxiliary supporting structure for a planetary mechanism assembly of a planetary transmission pair speed changer of an automobile speed changer. A bearing is arranged to assist in supporting the planetary mechanism assembly, so that load unbalance caused by backlashes of a planetary gear and a sun gear, part processing error of a planetary mechanism and the like is eliminated effectively and early damage of parts is avoided. An auxiliary speed changer serves as a combined multi-gear speed changer with a planetary transmission structure. The auxiliary supporting structure has a wide popularization prospect in medium and light commercial vehicles.
Description
Technical field
The invention discloses in the automobile combined type multi-speed transmission,, belong to the vehicle transmission technical field the structure of the planetary mechanism assembly in the auxiliary transmission that adopts the Gear Planet Transmission technology with floating bearing enforcement aiding support.
Background technique
At present, international, more and more universal with interior commercial car use combined type multi-speed transmission.And auxiliary transmission adopts the also more and more of Gear Planet Transmission structure technology, because the particularity of planetary mechanism assembly cantilever structure, external product requires very high to the planetary mechanism assembly part form and position tolerance in the planetary structure auxiliary transmission, quality of fit.But in being applied in, light-duty commercial car speed changer, restricted by manufacturing, use, service cost, can only adopt economic accuracy, therefore need different technology is adopted in the supporting of planetary mechanism assembly.
Summary of the invention
In order to address the above problem, the present invention creatively implements structure of assistant support to the planetary mechanism assembly with floating bearing, has solved an above-mentioned difficult problem.Auxiliary transmission is the combined type multi-speed transmission of Gear Planet Transmission structure, in, promote the use of in the light-duty commercial car wide prospect be provided.
To achieve these goals, the technical solution adopted in the present invention is:
Automotive transmission planetary-gear auxiliary transmission planetary mechanism assembly structure of assistant support, this aiding support bearing inner race of stating structure is installed in the output terminal of second of basic trnasmission, and float on planet carrier and install in the outer ring, by the locking nut axially locating; Auxiliary transmission input gear (sun gear) is fixed on second of basic trnasmission by spline and goes up or make one with second of basic trnasmission, and output shaft and planet carrier are fixed into a rigid unitary, are bearing on the rear case by roller bearing; The engagement of the gear ring of planetary mechanism and planet wheel can be realized locking or freely rotated simultaneously by locking plate; The high and low shift synchronizer is installed in gear ring and is unified on the supporting base of rigid unitary, and the top of high and low shift synchromesh unit assembly is provided with the compressed air gearshift by gear shifting handle control.
After adopting such scheme, the present invention makes aiding support by increasing by a bearing to the planetary mechanism assembly, thereby effectively eliminates the load imbalance that causes because of planet wheel and sun gear sideshake and planetary mechanism part's machining errors etc., avoids part to damage in early days.
Figure of description
Fig. 1 is the structural representation of preferred embodiment of the present invention.
Specific embodiment
As shown in the figure, aiding support bearing 3 inner rings of the present invention are fixed on the locking nut 2, and the outer ring Spielpassung is installed in the planetary mechanism on the planet carrier 4, and certain amount of floating is arranged.Auxiliary transmission input gear (sun gear) 1 directly and second of basic trnasmission be made of one (or being fixed on by spline on second of basic trnasmission); In the planetary mechanism planet wheel 5 by the needle bearing sky be enclosed within on the planet wheel shaft 6, planet wheel shaft 6 directly is bearing on the planet carrier 4, planetary mechanism assembly one end is bearing in rear case 10, one ends by roller bearing 9 and is meshed with sun gear 1 by planet wheel 5; Supporting base 7 floats on deep groove ball bearing 8 simultaneously, and the outer ring and the supporting base of deep groove ball bearing 8 leave the gap, realizes floating of planetary mechanism components and parts.
The present invention is at the front end of planetary mechanism, and second output terminal of basic trnasmission increases adorns a deep groove ball bearing 3, and planet carrier 4 floating supports leave micro-gap on its outer ring.Realize the planetary mechanism two supports, thereby effectively eliminate the load imbalance that causes because of planet wheel and sun gear sideshake and planetary mechanism part's machining errors etc., avoid part to damage in early days.
The foregoing description only be used to explain the present invention design, but not to the qualification of rights protection of the present invention allly utilizes this design that the present invention is carried out the change of unsubstantiality, all should fall into protection scope of the present invention.
Claims (2)
1. automotive transmission planetary-gear auxiliary transmission planetary mechanism assembly structure of assistant support, comprise planet carrier (4) in aiding support bearing (3), the auxiliary transmission, it is characterized in that: described speed changer has increased the structure of assistant support design at basic trnasmission output terminal, auxiliary transmission input end.
2. automotive transmission planetary-gear auxiliary transmission planetary mechanism assembly structure of assistant support as claimed in claim 1, described structure of assistant support design is applicable to that all auxiliary transmissions are many grades of automotive transmissions of combined type of Gear Planet Transmission structure technology.
