Abstract
The invention mainly discloses a lubrication mechanism in a planetary-gear auxiliary transmission, which is a creative structure. The combined multi-gearshifting transmission used for commercial vehicles at home and abroad is increasingly popularized. The auxiliary transmission increasingly adopts the ZF planetary-gear structure technique; and the planetary-structure auxiliary transmission uses an own lubricant pump for forced lubrication. However, the transmissions for the medium and light commercial vehicles can not use the lubricant pump to lubricate due to the limitation of overall structure, manufacture, use and service cost. The invention provides lubrication for the planetary-structure auxiliary transmission by creatively using the simple and reliable oil-mixing impeller structure, thereby solving the problems. The invention provides wide prospects for the popularization of the combined multi-gearshifting transmission the auxiliary transmission of which is in a planetary gear structure in medium and light commercial vehicles.
Description
Technical field
The invention discloses in the automobile combined type multi-speed transmission, a kind of structure to the auxiliary transmission that adopts the Gear Planet Transmission technology is lubricated belongs to the vehicle transmission technical field.
Background technology
At present, international, more and more universal with interior commercial car use assemble multi-gear gearshift.And auxiliary transmission adopts the also more and more of planetary transmission structure technology, and what due to the particularity of structure, the planetary structure auxiliary transmission is adopted is to carry lubricating pump, forced feed lubrication.But in, the light commercial vehicle speed changer, restricted by general structure and manufacturing, use, cost of serving, can't adopt built-in oil pump lubrication technology.
Summary of the invention
In order to address the above problem, the present invention is creatively easy to use stirs oily blade wheel structure reliably, for the planetary structure auxiliary transmission provides lubricated, has solved an above-mentioned difficult problem.Auxiliary transmission is the assemble multi-gear gearshift of planetary transmission structure, in, promote the use of the prospect that provides wide in light commercial vehicle.
To achieve these goals, the technical solution adopted in the present invention is:
Described structure stir the output that oily impeller is arranged on basic transmission the second axle, by the sun gear of planetary mechanism or directly compress, oily vane rotary is stirred in basic transmission the second axle drive by locking nut.Auxiliary transmission input gear (sun gear) is fixed on the second axle of basic transmission or makes one with basic transmission the second axle by spline, output shaft and planet carrier are fixed into a rigid unitary, are bearing on back casing by cylinder roller bearing; The gear ring of planetary mechanism and planetary gear engagement can be realized locking or freely be rotated by locking plate simultaneously; The high and low shift synchronizer 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.
After adopting such scheme, the present invention by the oily impeller shaft of stirring of particular design to fan-out lubricating oil, for the gear in planetary transmission structure, bearing, synchronizer etc. provide lubricated.
Description of drawings
Fig. 1 is the structural representation of preferred embodiment of the present invention;
Fig. 2 stirs the front schematic view of oily impeller in preferred embodiment of the present invention.
Embodiment
In conjunction with Fig. 1, Fig. 2, the present invention is described in further details.
As shown in the figure, of the present inventionly stir the second axle 1 output that oily impeller 2 is fixed on basic transmission, by the sun gear 3 of planetary mechanism or direct compression, realize axial location by locking nut 9.Auxiliary transmission input gear (sun gear) 3 be fixed on the second axle 1 of basic transmission by spline or directly and the second axle 1 of basic transmission be made of one.In planetary mechanism 4 planetary gear by the needle bearing empty set on planet wheel spindle, planet wheel spindle directly is bearing on planet carrier, planetary mechanism 4 one ends are bearing in back casing 8, one ends by cylinder roller bearing 7 and are meshed with sun gear 3 by planetary gear.Supporting base floats on deep groove ball bearing 5 simultaneously, and outer ring and the supporting base of deep groove ball bearing 5 leave the gap, realizes floating of planetary mechanism components and parts.High and low shift synchronizer assembly 6 is fixed on supporting base.
The present invention is at the front end of planetary mechanism, basic transmission the second axle output is installed in addition with one and simple and easyly stirs reliably oily impeller, during because of automobile traveling, the second axle of basic transmission often turns, drive is stirred oily impeller and is not stopped rotation, thereby to the enough lubricating oil of planetary mechanism fan-out, lubrication needs when effectively satisfying the work such as gear in planetary transmission structure, bearing, synchronizer.
Above-described embodiment the present invention's design that only is used for explaining, but not to the restriction of 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.
Claims (2)
1. the lubricating structure in planetary-gear auxiliary transmission, comprise and stir planetary mechanism in oily impeller, auxiliary transmission, it is characterized in that: described speed changer has increased at basic transmission output, auxiliary transmission input and has stirred oily blade wheel structure; Wherein stir oily impeller and passed through the sun gear of planetary mechanism or directly compressed by locking nut, basic transmission the second axle drives and stirs oily vane rotary; The auxiliary transmission input gear is fixed on the second axle of basic transmission or makes one with basic transmission the second axle by spline, output shaft and planet carrier are fixed into a rigid unitary, are bearing on back casing by cylinder roller bearing; The gear ring of planetary mechanism and planetary gear engagement can be realized locking or freely be rotated by locking plate simultaneously; The high and low shift synchronizer 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.
