Abstract
The utility model provides a heat dissipation structure of a transmission. The heat dissipation structure comprises a front shell and a main shell which are mutually connected and fixed; a first oil passage and a second oil passage which are arranged in an 'L' shape are arranged in the front shell; the main shell is provided with an oil spray pipe; the first oil passage of the front shell is communicated with an oil pump outlet of the transmission; and the second oil passage of the front shell is communicated with the oil spray pipe. The heat dissipation structure is characterized in that a first hollow bolt and a second hollow bolt are arranged at the bottom of the front shell, the top of the first hollow bolt is axially inserted into the first oil passage, the inserted section of the first hollow bolt partitions the first oil passage and the second oil passage, and the second hollow bolt is communicated with the second oil passage; and the neck of the first hollow bolt is communicated with a connector of a radiator through an oil outlet pipe, and the neck of the second hollow bolt is communicated with the other connector of the radiator through an oil inlet pipe. According to the heat dissipation structure, lubricating oil can be cooled through the radiator, so that the fault rate of the transmission due to a high temperature is reduced, and the working stability of the transmission is improved.
Description
Technical field
The utility model relates to automotive transmission, relates in particular to the speed changer radiating structure.
Background technique
Along with the trend that increases day by day of logistics transportation, the heavy truck industry obtains develop rapidly.And various abominable traffic conditions are just testing the performance of auto parts and components.As everyone knows, heavy truck transmission is big owing to the special delivery moment of torsion, overload, work in reason such as high temperature area, desert, causes the temperature of lubricant oil of speed changer higher, causes TRANS PROGRAM easily, therefore must lower the temperature to the lubricant oil of speed changer.Referring to Fig. 2; Existing speed changer comprises and interconnects fixing front case 1 and main casing 2, is provided with the first oil duct 1a and the second oil duct 1b of L-shaped connection in the front case 1, and main casing 2 is provided with spray bar 4; The first oil duct 1a of front case is used for communicating with the oil pump outlet of speed changer; The second oil duct 1b of front case communicates with spray bar 4, and the flow of lubricant of oil pump outlet gets into the spray bar 4 of main casing through the first oil duct 1a, the second oil duct 1b of front case; Transmission gear is lubricated, and lubricant oil can not effectively be lowered the temperature in this flow process.
The model utility content
The technical problem that the utility model solves is: a kind of speed changer radiating structure is provided, can lowers the temperature to the lubricant oil in the speed changer.
The technological scheme of the utility model is: a kind of speed changer radiating structure; Comprise and interconnect fixing front case and main casing; First oil duct and second oil duct that are provided with " L " shape to arrange in the front case, main casing is provided with spray bar, and first oil duct of front case is used for communicating with the oil pump outlet of speed changer; Second oil duct of front case communicates with spray bar; It is characterized in that the bottom of said front case is provided with first hollow bolt and second hollow bolt, the top axle of said first hollow bolt is in inserting said first oil duct; And the insertion section of first hollow bolt is with sealed separation between first oil duct and second oil duct, and said second hollow bolt communicates with said second oil duct; The neck of first hollow bolt is communicated with two interfaces of a radiator respectively through oil inlet pipe through the neck of oil outlet tube, second hollow bolt.
The neck of said first hollow bolt is provided with first fittings body; First hollow bolt is communicated with said oil outlet tube through said first fittings body; The neck of said second hollow bolt is provided with second fittings body, and second hollow bolt is communicated with said oil inlet pipe through said second fittings body.
The beneficial effect of the utility model is: the utility model is connected with radiator through first hollow bolt, second hollow bolt; Lubricant oil flows through first oil duct, first hollow bolt, radiator, second hollow bolt and second oil duct of front case successively; Get into the spray bar of main casing at last; Transmission gear is carried out oil jet lubrication; Lubricant oil can be lowered the temperature through radiator in this flow process, has reduced speed changer because the rate of fault that high temperature causes has improved the stability of speed changer work.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the prior art constructions schematic representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1, a kind of speed changer radiating structure comprises interconnecting fixing front case 1 and main casing 2, and a radiator 3.Be provided with the first oil duct 1a and the second oil duct 1b of L-shaped layout in the front case 1; Main casing 2 is provided with spray bar 4; The first oil duct 1a of front case is used for communicating with the oil pump outlet of speed changer; The second oil duct 1b of front case communicates with the spray bar 4 on the main casing, and the bottom of front case 1 is connected with the top axle of first hollow bolt 5 and second hollow bolt, 6, the first hollow bolts 5 in inserting the first oil duct 1a through tapped hole; And the insertion section of first hollow bolt 5 is with complete sealed separation between the first oil duct 1a and the second oil duct 1b, and second hollow bolt 6 communicates with the second oil duct 1b of front case.The neck of first hollow bolt 5 is communicated with two interfaces of radiator 3 respectively through oil inlet pipe 8 through the neck of oil outlet tube 7, second hollow bolt 6; Wherein, The neck of first hollow bolt 5 is provided with first fittings body 9; First fittings body 9 is fixed on front case 1 bottom through first hollow bolt 5, and first hollow bolt 5 is communicated with oil outlet tube 7 through first fittings body 9.The neck of second hollow bolt 6 is provided with second fittings body, 10, the second fittings bodies 10 and is fixed on front case 1 bottom through second hollow bolt 6, and second hollow bolt 6 is communicated with oil inlet pipe 8 through second fittings body 10.
The working principle of the utility model is: the higher lubricant oil of temperature that comes from transmission oil pump; Get into first hollow bolt from first oil duct of front case, and get into oil outlet tube, get into radiator then from first fittings body; This moment, lubricant oil obtained cooling; Cooled lubricant oil gets into second fittings body from oil inlet pipe, and passes through second oil duct that second hollow bolt gets into front case, and last lubricant oil gets into spray bar gear is carried out oil jet lubrication.Radiator can be installed on the speed changer; Also can be installed to the position that ventilates on the vehicle frame; When not needing external radiator; First hollow bolt and second hollow bolt are taken out from two threaded couplings of front case, the oil duct of winning directly is communicated with second oil duct, two threaded couplings seal with the hexagon head plug screw.
