Abstract
The utility model provides a 12-gear transmission, mainly aiming at solving the problem that for the existing transmission, parts needing to be lubricated cannot be effectively lubricated when an operating angle is too large. The 12-gear transmission comprises an input shaft, a main shaft and an output shaft which are connected in sequence, wherein an oil inlet hole communicated with the outside of the input shaft is arranged on the input shaft; an oil transportation passage of the input shaft is arranged in the center of the input shaft along the axial direction; one end of the oil transportation passage of the input shaft is communicated with the oil inlet hole; an oil transportation passage of the main shaft is arranged in the center of the main shaft along the axial direction and is communicated back and forth; and the other end of the oil transportation passage of the input shaft is communicated with the oil transportation passage of the main shaft in a seamless way or in a gap fit way. According to the 12-gear transmission, the lubrication oil transportation passages are arranged in the centers of the input shaft, the main shaft and the output shaft, so that the lubrication efficiency is effectively improved.
Description
Technical field
The utility model relates to a kind of 12 shift transmissions, is specifically related to a kind of lubrication system of heavy-duty car 12 shift transmissions.
Background technique
The inner lubricating system of tradition speed changer is generally splash lubrication, no effective lubricating oil system; When making operating angle when speed changer big like this, the lubricant oil of case of transmission bottom will concentrate on and hang down a side, cause the component lubrications such as gear and bearing of a higher side bad.
Summary of the invention
12 shift transmissions that the utility model provides have mainly solved existing speed changer insufficient lubrication when operating angle is big, the problem that can't effectively be lubricated each parts that need lubricate.
The concrete technical solution of the utility model is following:
This 12 shift transmission; Comprise the main tank that is provided with 6 gears and the odd-side of 2 gears; Be provided with input shaft, main shaft and the odd-side main shaft (being output shaft) that is connected successively in main tank and the odd-side; Input shaft is provided with the oil inlet hole with the input shaft external communications, and the input shaft center is provided with the input shaft oil transportation channel vertically, and input shaft oil transportation channel one end is communicated with oil inlet hole; The said alignment of shafts is provided with the main shaft oil transportation channel vertically and front and back connect, and the input shaft oil transportation channel the other end is communicated with or the Spielpassung connection with the main shaft oil transportation channel is seamless; Said main shaft is provided with the lubrication hole of at least one and main shaft external communications.
The above-mentioned input shaft oil transportation channel the other end overlaps seamless the connection or the Spielpassung connection with the main shaft oil transportation channel through Oil Guide; In the actual production, for the ease of assembling, there is small radial clearance in the Oil Guide cover with the oil transportation channel hole of main shaft, belongs to Spielpassung, when lubricant oil passes through this place, micro-seepage is arranged, and belongs to normal.
The quantity of above-mentioned lubrication hole be arranged on main shaft on the number of spare parts that need be lubricated identical, the central shaft of lubrication hole is vertical with the central shaft of main shaft.
The central shaft of above-mentioned oil inlet hole is perpendicular to the central shaft of input shaft.
Above-mentioned main shaft is connected with output shaft away from input shaft one end, and the output shaft center is provided with oil transportation channel vertically, and is provided with the lubrication hole of at least one and output shaft external communications; The main shaft oil transportation channel is communicated with or the Spielpassung connection with the output shaft oil transportation channel is seamless.
Above-mentioned main shaft oil transportation channel overlaps seamless the connection or the Spielpassung connection with the output shaft oil transportation channel through Oil Guide.
The advantage of the utility model is:
This 12 shift transmission; Owing to be provided with the lubricant oil oil transportation channel at input shaft, main shaft and output shaft center; Speed changer drives main shaft, output shaft rotation through input shaft when work, lubricant oil is thrown away from the lubrication hole that is communicated with main shaft oil transportation channel, output shaft oil transportation channel respectively be lubricated; And the parts that the position of each lubrication hole all is lubricated corresponding to needs, lubricating efficiency effectively improves.
The lubrication system architecture of this 12 shift transmission is simple, applicable to the speed changer of various different models.
Description of drawings
Fig. 1 is the utility model structural representation.
Accompanying drawing is detailed: the 1-input shaft; The 2-main shaft; The 3-oil inlet hole; 4-input shaft oil transportation channel; 5-main shaft oil transportation channel; 6-Oil Guide cover; The 7-lubrication hole; 8-odd-side main shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is detailed, as shown in Figure 1:
This 12 shift transmission comprises the main tank that is provided with 6 gears and the odd-side of 2 gears, is provided with input shaft, main shaft and the odd-side main shaft (being output shaft) that is connected successively in main tank and the odd-side; Input shaft is provided with the oil inlet hole with the input shaft external communications, and generally the central shaft of this oil inlet hole is perpendicular to the central shaft of input shaft, and oil inlet hole one end is connected with input shaft is outside, is used to make lubricant oil to pass through variety of way and gets in the input shaft;
The input shaft center is provided with the input shaft oil transportation channel vertically; Input shaft oil transportation channel one end is communicated with oil inlet hole; The alignment of shafts is provided with the main shaft oil transportation channel vertically and front and back connect, and the input shaft oil transportation channel the other end is communicated with or the Spielpassung connection with the main shaft oil transportation channel is seamless.
Main shaft is provided with the lubrication hole of at least one and main shaft external communications; The central shaft of lubrication hole and the central shaft of main shaft with vertical be good; The quantity of general lubrication hole be arranged on main shaft on the number of spare parts that need be lubricated identical, all can obtain effective lubricating with each part of guaranteeing to be arranged on the main shaft.
Main shaft is connected with output shaft away from input shaft one end, and the output shaft center is provided with oil transportation channel vertically, and is provided with the lubrication hole of at least one and output shaft external communications; The main shaft oil transportation channel is connected through the Oil Guide cover with the output shaft oil transportation channel.Principle is identical with above-mentioned principal axis lubrication principle.
During use; Lubricant oil gets into the input shaft oil transportation channel in the input shaft through oil inlet hole; And then cover into main shaft oil transportation channel and the oil transportation channel of output shaft in the main shaft through Oil Guide, because input shaft can drive main shaft, output shaft is rotated, therefore; Under action of centrifugal force; Lubricant oil in main shaft oil transportation channel and the output shaft oil transportation channel will throw away through lubrication hole, because each lubrication hole all with on being arranged on main shaft or output shaft needs lubricated part position corresponding, so can carry out effective lubricating to the part that need be lubricated on main shaft and the output shaft after lubricant oil throws away.
