Description

Technical Field

[0001] This utility model belongs to the field of automotive transmission technology, and in particular relates to an energy-saving two-speed transmission for automobiles. Background Technology

[0002] A car transmission is a gearbox that coordinates the engine speed and the actual speed of the wheels to optimize engine performance. Transmissions can create different gear ratios between the engine and wheels during vehicle operation; two-speed transmissions are widely used in new energy vehicles.

[0003] To avoid increased operating resistance, excessive pressure, and foam formation, the amount of lubricating oil in the transmission is determined according to its design requirements and is generally maintained at a suitable level, without filling the entire transmission.

[0004] Currently, the lubricating oil in the transmission only lubricates the gears and cannot clean the dirt on the gear surfaces and in the grooves. Long-term accumulation of dirt may cause wear between the gears and increase the burden on subsequent transmission maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving two-speed transmission for automobiles in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an energy-saving two-speed transmission for automobiles, comprising a transmission body, a spray bar, an oil pump, and a filter element assembly. The spray bar is installed inside the transmission body and is located above the gear assembly of the transmission body. The spray bar is provided with multiple nozzles. The filter element assembly is installed at the bottom of the transmission body. The oil pump is installed inside the filter element assembly and is connected to the spray bar through an oil pipe.

[0007] As a further description of the above technical solution:

[0008] The filter element assembly includes a filter element shell and a filter element body. A screw hole is provided at the bottom of the transmission body. The filter element shell is screwed into the screw hole. The filter element body is fixedly connected to the filter element shell. An oil inlet gap is formed between the filter element body and the inner wall of the filter element shell. The oil pump is installed in the middle of the filter element body.

[0009] As a further description of the above technical solution:

[0010] The oil pipe is located on one side of the gear assembly.

[0011] As a further description of the above technical solution:

[0012] The spray bar is cylindrical, and the inner diameter of the oil pipe is not less than the inner diameter of the spray bar.

[0013] As a further description of the above technical solution:

[0014] The filter housing extends to the outside of the transmission body.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, an oil pump installed in the transmission draws lubricating oil into a spray bar. The nozzle on the spray bar sprays lubricating oil onto the gear assembly, thereby cleaning the dirt on the gear surface and in the grooves. The filter element assembly cleans and filters the lubricating oil before it enters the oil pump, avoiding secondary pollution. This solves the wear problem of gear assembly caused by long-term dirt accumulation and reduces the burden of subsequent transmission maintenance.

[0017] 2. In this utility model, dirty lubricating oil flows from the inside of the transmission body into the oil inlet gap and is filtered by the filter element body, ensuring that the lubricating oil drawn out by the oil pump is clean, thus avoiding secondary pollution of the gear assembly during the cleaning process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution: an energy-saving two-speed transmission for automobiles, including a transmission body 1, a spray bar 2, an oil pump 3, and a filter element assembly 4. The spray bar 2 is installed inside the transmission body 1 and is located above the gear assembly 5 of the transmission body 1. The spray bar 2 is provided with multiple nozzles 6. The filter element assembly 4 is installed at the bottom of the transmission body 1. The oil pump 3 is installed inside the filter element assembly 4 and is connected to the spray bar 2 through an oil pipe 7.

[0027] The filter element assembly 4 includes a filter element shell 41 and a filter element body 42. A screw hole 8 is provided at the bottom of the transmission body 1. The filter element shell 41 is screwed into the screw hole 8. The filter element body 42 is fixedly connected to the filter element shell 41. An oil inlet gap 9 is formed between the filter element body 42 and the inner wall of the filter element shell 41. The oil pump 3 is installed in the middle of the filter element body 42. Dirty lubricating oil flows from the inside of the transmission body 1 into the oil inlet gap 9. After being filtered by the filter element body 42, the lubricating oil drawn out by the oil pump 3 is ensured to be clean, thus avoiding secondary contamination of the gear assembly 5 during the cleaning process.

[0028] The oil pipe 7 is located on one side of the gear assembly 5 to avoid interfering with the normal operation of the gear assembly 5;

[0029] The spray bar 2 is cylindrical, and the inner diameter of the oil pipe 7 is not less than the inner diameter of the spray bar 2, ensuring that there is a certain pressure inside the spray bar 2, so that when the lubricating oil is sprayed out from the nozzle 6, it has enough force to remove dirt from the gear surface and grooves.

[0030] The filter housing 41 extends to the outside of the transmission body 1, facilitating the replacement of the filter assembly 4 from the outside of the transmission body 1.

[0031] Working principle: First, dirty lubricating oil flows from the inside of the transmission body 1 into the oil inlet gap 9. After being filtered by the filter element body 42, the lubricating oil drawn out by the oil pump 3 is ensured to be clean. Second, the oil pump 3 draws the clean lubricating oil into the spray bar 2 through the oil pipe 7. The nozzle 6 on the spray bar 2 sprays the lubricating oil onto the gear assembly 5, thereby cleaning the dirt on the gear surface and in the grooves. Finally, when the transmission body 1 is being maintained, the filter element housing 41 can be unscrewed from the screw hole 8 to replace the filter element body 42.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
