Vehicle and power device thereof

Abstract

The invention relates to a vehicle and a power device thereof. The power device comprises a device shell. The device shell is internally provided with a motor and a planet row, further provided with abearing mounting position used for mounting of a corresponding bearing, and internally provided with a lubricating oil pump; the lubricating oil pump is provided with a power input end in transmission connection with the planet row; the power device further comprises a lubricating oil channel connected with an oil outlet of the lubricating oil pump for guiding lubricating oil towards the planet row and / or the mounting position of the corresponding bearing; and the lubricating oil channel is constituted by an oil pipe and / or an oil hole formed in the device shell. According to the power device, the oil is not liable to leak when a to-be-lubricated part is lubricated forcibly, and the power device is used for a hybrid power system and the vehicle.

Description

technical field [0001] The present invention relates to a vehicle and its power plant. Background technique [0002] With the increasing pressure of environmental pollution and the increasingly prominent environmental pollution problems, the development of energy-saving and environmentally friendly vehicles has become one of the important tasks of automobile manufacturers. Vehicles using hybrid systems are more and more supported by consumers and the industry due to their advantages such as not being affected by charging equipment and charging time, unlimited driving range, and significant energy saving performance. [0003] Common hybrid systems have three forms: series, parallel and hybrid. In the series hybrid system, the kinetic energy output by the engine is converted by the first electric motor into electric energy and then drives the vehicle. Because the energy has been converted twice, the energy loss is too large, saving energy. The effect is relatively poor. In t...

Problems solved by technology

However, the system still has the following problems at present: the device housing and the corresponding parts installed on the device housing need to be rotated and matched through bearings. 1. Bearings are installed on the rear transmission shaft bearing seat to realize the rotation fit between the device housing and the corresponding transmission shaft. The front and rear motor bearing seats need to be installed at the two ends of the first motor chamber and the planetary row chamber respectively. Bearings are installed on the bearing seat of the rear motor to realize the rotation fit between the rotor and the device housing. These positions where the bearings are installed need to be lubricated, and the position of the planetary row also needs to be lubricated. The current lubrication method is to fill these parts that need to be lubricated. Grease, the use of grease to lubricate these parts has the following defects. The grease may be displaced from the parts to be lubricated, resulting in the inability to continue to lubricate the parts to be lubricated, which may cause damage to bearings, gears, etc.; The generated impurities are taken away, the heat dissipation effect is not good, and the replacement of lubricating grease is also troublesome

And if the lubricating oil pump is simply provided to force these parts to be lubricated to be lubricated, in order to supply power to the lubricating oil pump, cable perforations must be set on the device housing, which involves new sealing problems, or leads to The structure of the whole device shell is more complex and prone to oil leakage
