The input shaft consists of a shaft body, a spring groove, a spring, a middle hole and a radial hole, wherein the spring groove is formed on the end part of the shaft body; the spring is arranged in the spring groove; one end of the middle hole is communicated with the spring groove; and the radial hole is communicated with the other end of the middle hole, and passes through the shaft body. Improvements are that: the spring groove is trumpet-shaped; and the spring has the same trumpet-shaped structure as the shape of the spring groove.
Description
Technical field
The utility model relates to a kind of transmission shaft, relates in particular to a kind of input shaft that improves heavy-duty car ransaxle lubrication effect.
Background technique
In the existing heavy-duty car ransaxle system, input shaft upper spring groove place end is socketed in the endoporus of back differential gear, spring groove is communicated with the endoporus of back differential gear, the outer end of the spring in the spring groove withstands on the end that connects axle, the oil of lubricated usefulness enters the endoporus of back differential gear from back differential gear outer wall by the oilhole on the differential gear of back, enter in the mesopore of axis body by spring groove again, radial hole from the axis body flows to the input shaft outer wall again, is lubricated being socketed in the outer triple gear of input shaft.
Spring groove on the existing input shaft is straight tube groove, considers structure stability, and the aperture of spring groove is less, and the oil mass that enters is limited, and lubrication effect is poor.
The model utility content
At the problem in the background technique, in order to increase the oil mass that enters input shaft, the utility model proposes a kind of input shaft that improves heavy-duty car ransaxle lubrication effect, it is made up of axis body, the spring groove that is arranged on the axis body end, the radial hole that is arranged at spring in the spring groove, mesopore that an end is communicated with spring groove, is communicated with the mesopore the other end and runs through axis body, its improvement is: described spring groove is a broadening formation, and spring is the horn shape identical with the spring groove shape.
Axis body upper spring groove place end is socketed in the differential gear of back, and back differential gear is provided with axial arranged endoporus of back, edge differential gear and the one or more oilhole that runs through the endoporus sidewall.
The central shaft spatial vertical of the central shaft of each oilhole and endoporus and non-intersect.
The intersection location of the central shaft of arbitrary oilhole and endoporus sidewall, back differential gear sense of rotation are in the tangential direction at this intersection location place, and the angle of the central shaft of this tangential direction and oilhole is the obtuse angle.
The central shaft of each oilhole is in the same cross section of endoporus.
The position of each oilhole circumferentially is symmetrical arranged along the back differential gear.
Useful technique effect of the present utility model is: can allow more oil enter in the mesopore of input shaft, provide better lubrication effect to follow-up parts.

Embodiment
Structure of the present utility model is: it is by axis body 3, be arranged on the spring groove 3-1 of axis body 3 ends, be arranged at the spring in the spring groove 3-1, the mesopore 3-3 that one end is communicated with spring groove 3-1, the radial hole 3-4 composition that is communicated with and runs through axis body 3 with the mesopore 3-3 the other end, the structure that the heavy-duty car ransaxle of being made up of the utility model and miscellaneous part connects the jackshaft place is: back differential gear 2 is embedded in the bevel housing 1, one end of perforation axle 4 is socketed in the left part among the endoporus 2-1, one end of input shaft 3 is socketed in the right part (opening portion of spring groove 3-1 is communicated with endoporus 2-1) among the endoporus 2-1, the outer race at the middle part of input shaft 3 is connected on the mesopore interior (radial hole 3-4 outer end is communicated with the mesopore of triple gear 5) of triple gear 5, and triple gear 5 passes through two poor shell components 7 with back differential gear 2, planetary pinion, cross axle is in transmission connection.During equipment work, the oil that gear sputters is deposited in the shoe cream room between back differential gear 2 and the bevel housing 1, and oil enters by oilhole 2-2 among the endoporus 2-1 of back differential gear 2 then, and the belled position of endoporus 2-1 and input shaft 3 is lubricated; Because endoporus 2-1 is communicated with the spring groove 3-1 of input shaft 3, part oil also flows to the position of input shaft 3 and triple gear 5 sockets by spring groove 3-1, mesopore 3-3, the radial hole 3-4 of input shaft 3, and this position is lubricated.
Spring groove 3-1 on the existing input shaft 3, its structure is a straight-tube, and the aperture is limited, oil stops up easily at spring groove 3-1 place, cause by spring groove 3-1 oil mass seldom, input shaft 3 can not get well lubricated with the position of triple gear 5 sockets, influence the work effect of parts, the improvement project that the utility model proposes is: spring groove 3-1 is set to broadening formation, spring is and the identical horn shape of spring groove 3-1 shape, this just can make oil enter the mesopore 3-3 of input shaft 3 more smoothly, has also just increased the oil mass that arrives input shaft 3 and triple gear 5 belled positions, has improved lubrication effect.
The utility model has also been done following improvement to the back differential gear 2 that is connected with input shaft 3:
Oilhole 2-2 on the differential gear 2 of existing back adopts the straight hole structure, have only oil seldom can enter differential gear 2 inside, back, lubrication effect is very limited, but also it is influential with the lubrication effect of triple gear 5 belled positions to input shaft 3, at this problem, the inventor has proposed following improvement project: make the central shaft spatial vertical of the central shaft of oilhole 2-2 and endoporus 2-1 and non-intersect, be about to straight hole and change inclined hole into, inclined hole can allow more oil enter among the endoporus 2-1 with respect to straight hole, and parts are played better lubrication effect.
Further, that adjusts oilhole 2-2 can further increase the oil mass that enters oilhole 2-2 towards (with the tangential angle of sense of rotation), the intersection location of the central shaft of arbitrary oilhole 2-2 and endoporus 2-1 sidewall, back differential gear 2 sense of rotation are in the tangential direction at this intersection location place, and the angle of the central shaft of this tangential direction and oilhole 2-2 is the obtuse angle.
Further, the central shaft of each oilhole 2-2 can be arranged in the same cross section of endoporus 2-1.
Also the position of each oilhole 2-2 circumferentially can be symmetrical arranged along the back differential gear.
