Abstract
The invention discloses a structure for lubricating an auxiliary transmission adopting a planetary transmission technique in a combined multi-gear transmission of a medium and light vehicle, and belongs to the technical field of vehicle transmission. The structure comprises an auxiliary transmission planetary mechanism mounted in a main transmission shell. An oil collection and delivery groove structure is arranged in an inner cavity of the main transmission shell, and comprises an oil collection and lubrication groove axially positioned on the inner side of the box wall of the main transmission shell. The tail end of the oil collection and lubrication groove with a high front and a low rear is communicated with an oil outlet hole, used for allowing oil to flow from a main box inner cavity to an auxiliary box inner cavity, in a supporting wall of a gap between the main box inner cavity and the auxiliary box inner cavity. A backflow oil hole for allowing the oil to flow from the auxiliary box inner cavity to the main box inner cavity is further formed in the supporting wall of the gap between the main box inner cavity and the auxiliary box inner cavity and at a position higher than the position of the oil outlet hole for allowing the oil to flow from the main box inner cavity to the auxiliary box inner cavity. The simple, convenient and reliable oil collection and delivery groove structure is creatively used in the inner cavity of the main transmission shell so as to lubricate an auxiliary transmission with a planetary structure, and the problems in the prior art are solved.
Description
Technical field
The invention discloses, in light-duty vehicle assemble multi-gear gearshift, a kind of structure to adopting the auxiliary transmission of Gear Planet Transmission technology to be lubricated, belongs to vehicle transmission technical field.
Background technique
At present, international, domestic commercial vehicle is used assemble multi-gear gearshift more and more universal, and auxiliary transmission adopts the also more and more of planetary transmission structure technology, what heavily block that speed changer adopts planetary structure auxiliary transmission due to the particularity of structure is to carry lubricant pump, pressure lubrication.But in, light commercial vehicle speed changer, restricted by general structure and manufacture, use, service cost, cannot adopt built-in oil pump lubrication technology.
Summary of the invention
In order to address the above problem, the present invention creatively uses and utilizes basic trnasmission housing shaft oil-collecting delivery chute structure to the inside, easy reliably for planetary structure auxiliary transmission provides lubricated, has solved an above-mentioned difficult problem.For auxiliary transmission be planetary transmission structure in, light-duty assemble multi-gear gearshift, in, in light commercial vehicle, promote the use of the prospect that provides wide.
To achieve these goals, the technical solution adopted in the present invention is:
In a kind of, the lubricating structure of light vehicle transmission planetary structure auxiliary transmission, comprise the auxiliary transmission planetary mechanism being arranged in basic trnasmission housing, described basic trnasmission housing inner chamber is provided with oil-collecting delivery chute structure, this oil-collecting delivery chute structure comprises on the axial inner side of tank wall that is positioned at basic trnasmission housing, low after front height, tail end flows out to odd-side inner chamber the oil-collecting lubrication groove that oilhole is connected with the main tank inner chamber in the abutment wall of major and minor box cavity interval; Meanwhile, in the abutment wall of major and minor box cavity interval and higher than main tank inner chamber, on the position of odd-side inner chamber outflow oilhole, also opened odd-side inner chamber to main tank inner chamber backflow oilhole.Odd-side inner chamber is preferably two to main tank inner chamber backflow oilhole.
Sun gear in auxiliary transmission is fixed on the output shaft of basic trnasmission or makes one with basic trnasmission output shaft by spline, in planetary mechanism, output shaft and planet carrier are a rigid unitary, by roller bearing, are bearing on rear case; The gear ring of planetary mechanism and planet wheel engagement simultaneously, can be realized locking or freely be rotated by locking plate; High and low shift synchromesh unit assembly is arranged on 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 of being controlled by gear shifting handle.
Adopt after such scheme, when speed changer is worked, the present invention exports lubricant oil by the oil-collecting delivery chute of particular design from speed changer main tank inner chamber to odd-side inner chamber, thereby raise rapidly odd-side inner chamber lubricating oil level, for the gear in planetary transmission structure, bearing, high and low shift synchromesh unit etc. provide lubricated.
During the present invention is a kind of, the lubricating structure of light vehicle transmission planetary structure auxiliary transmission, be applicable to all auxiliary transmissions and be planetary transmission structure technology in, light many grades of automotive transmissions of combined type.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the right TV structure schematic diagram of basic trnasmission housing in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, during the present invention is a kind of, the lubricating structure of light vehicle transmission planetary structure auxiliary transmission, comprise the auxiliary transmission planetary mechanism 4 being arranged in basic trnasmission housing 3, basic trnasmission housing 3 inner chambers are provided with oil-collecting delivery chute structure.This oil-collecting delivery chute structure comprises that, on the axial inner side of tank wall that is positioned at basic trnasmission housing 3, low after front height, tail end flows out to odd-side inner chamber the oil-collecting lubrication groove 11 that oilhole 12 is connected with the main tank inner chamber in major and minor box cavity interval abutment wall 10; Meanwhile, in major and minor box cavity interval abutment wall 10 and a little higher than main tank inner chamber to odd-side inner chamber, flow out on the position of oilhole 12 and also opened two odd-side inner chambers to main tank inner chamber backflow oilhole 13.
The sun gear 2 of auxiliary transmission by spline, be fixed on the output shaft 1 of basic trnasmission or directly and the output shaft 1 of basic trnasmission be made of one; In planetary mechanism 4 planet wheel by needle bearing empty set on planet wheel shaft, planet wheel shaft is directly bearing on planet carrier, planetary mechanism 4 one end are bearing on rear case 6 by roller bearing 7, the other end is meshed with sun gear 2 by planet wheel; Pass through supporting base floating support on deep groove ball bearing 5, outer ring and the supporting base of deep groove ball bearing 5 leave gap simultaneously, realize floating of planetary mechanism components and parts; High and low shift synchromesh unit assembly 8 is fixed on supporting base.
When the present invention works at speed changer, oil-collecting lubrication groove 11 is collected the lubricant oil sputtering because of gear rotation from main tank, by the main tank inner chamber in major and minor box cavity interval abutment wall 10, to odd-side inner chamber, flow out oilhole 12 and carry lubricant oil to odd-side inner chamber, thereby raise rapidly the lubricated position of odd-side inner chamber; Odd-side inner chamber oil level, after certain altitude, to main tank inner chamber backflow oilhole 13 to the oil return of main tank inner chamber, forms the lubricated loop that circulates by two odd-side inner chambers in major and minor box cavity interval abutment wall 10.Lubrication needs while effectively meeting the work such as gear in planetary transmission structure, bearing, high and low shift synchromesh unit.
Above-described embodiment is only for explaining the present invention design, but not restriction to rights protection of the present invention, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should fall into protection scope of the present invention.
