Description

Vehicle torque converter assembly that can be installed at multiple angles

technical field

The invention relates to a hydraulic torque converter assembly, in particular to a hydraulic torque converter assembly which can be installed at multiple angles for special transport vehicles.

Background technique

At present, the hydraulic torque converter assembly of special transport vehicles has the following problems: due to the relatively fixed position of the oil drain port, the torque converter cannot be rotated and installed at multiple angles, but the whole vehicle is limited by the overall layout, which makes the hydraulic pressure The installation angle between the output flange of the torque converter assembly and the transmission shaft is too large, which often leads to early damage to the transmission shaft and output flange during use.

Contents of the invention

In order to solve the technical problem that the transmission shaft of the vehicle and the output flange of the hydraulic torque converter assembly are easily damaged due to the excessive installation angle between the output flange of the hydraulic torque converter assembly and the transmission shaft, the present invention provides a A hydraulic torque converter assembly for a vehicle installed at multiple angles.

Technical solution of the present invention:

The vehicle hydraulic torque converter assembly that can be installed at multiple angles includes a torque converter housing 3, an oil pan cover 10, a guide wheel seat 4, and a driving gear 7. The oil pan cover 10 divides the torque converter housing into three parts. It is a front chamber and a rear chamber, the front chamber is connected to the engine through an elastic plate, and the oil inlet 11 is arranged on the guide wheel seat, and its special feature is that: the torque converter housing 3 is provided with multiple Oil drain port 13, said oil drain port is located in the rear cavity.

A lubricating oil port 12 is arranged on the guide wheel seat, one end of the lubricating oil port 12 communicates with the oil inlet 11 , and the other end of the lubricating oil port 12 opens to the driving gear 7 .

There are four above-mentioned oil drain ports, and the oil drain ports are perpendicular to the circumferential surface of the housing, and the other end is connected with the gearbox housing through an oil pipe.

The above drain port is NPT1.

The torque converter housing 3 is provided with three power take-off ports.

The advantages that the present invention has:

1. The structure is compact and can be installed at multiple angles, which facilitates the overall layout of the vehicle, solves the frequent damage of the drive shaft and output flange, and reduces maintenance costs.

2. The reasonable design of the lubricating oil circuit and the oil drain port ensures that the gear pairs are fully lubricated when the torque converter assembly is installed at different angles and the transmission oil in the housing is drained to prevent gear damage.

3. There are lubricating oil passages on the casing and guide wheel seat, so that each pair of gear pairs can be fully lubricated in different installation positions of the assembly to prevent burning out.

Detailed ways

As shown in Figures 1 and 2, the hydraulic torque converter assembly for special transport vehicles that can be installed at multiple angles includes a hydraulic torque converter 1, a turbine shaft 2, a torque converter housing 3, a guide wheel seat 4, and an output shaft 5. Output flange 6, driving gear 7, circulating oil pump 8, pressure reducing valve 9, oil pan cover 10 and other main components. The oil pan cover 10 divides the torque converter housing 3 into a front cavity and a rear cavity;

The torque converter housing 3 is provided with four NPT1 oil drain ports around the rear cavity, so that the transmission assembly can ensure the transmission oil in the rear cavity to drain in different installation positions, and there is a certain amount of oil in the rear cavity of the housing. liquid.

Also be provided with lubricating oil port 12 on guide wheel seat, one end of lubricating oil port 12 communicates with oil inlet 11, and the other end of lubricating oil port 12 opens to drive gear 7, makes this hydraulic torque converter assembly realize multiple At the same time, the installation at different angles ensures that each pair of gear pairs is fully lubricated during operation and the transmission oil in the housing is drained, reducing damage to the output flange and transmission shaft.

The connection holes between the hydraulic torque converter assembly shell and the engine flywheel shell are 12 holes evenly distributed at 30°, and the front and rear chambers of the shell are separated by an oil pan cover to realize the separation of dry and wet inside the shell. Four NPT1 oil drain ports are designed around the rear chamber of the housing to realize the transmission oil leakage in the rear chamber under different installation positions, and at the same time ensure that there is a certain amount of oil in the rear chamber of the housing to provide gear splash lubrication. Lubricating oil channels are designed on the casing and guide wheel seat, so that each pair of gear pairs can be fully lubricated at different installation positions of the assembly to prevent burnout. There are three power take-off ports on the back of the housing, and the external connection dimensions are all the same to ensure coordinated installation in case of interference. In summary, the hydraulic torque converter assembly can be installed at multiple angles and has a compact structure.
