Problems solved by technology
[0004] In order to overcome the existing variable flow planetary gear water pump, in the process of after-cooling the engine, once the motor of the water pump fails to operate normally, the after-cooling cannot be performed in time to reduce the system temperature, resulting in the heat of the engine cooling system components. The load increases and the deformation of the cylinder head is insufficient. The invention provides a planetary gear type water pump motor shaft connection device

The invention relates to a planetary gear type water pump motor shaft connecting device. A gear ring of a planetary gear is driven to rotate by a crankshaft of an engine through a belt, a sun gear of the planetary gear is connected with a water pump shaft, and a planetary carrier shaft head of the planetary gear is connected with or disconnected from a motor shaft of the motor; the planetary carrier shaft head is connected with the motor shaft through a combining sleeve, or under the effect of a driving device, connection between the planetary carrier and the motor shaft is switched off by the combining sleeve; a driving device is fixedly connected with a water jacket; when the motor is in a good condition, the planetary carrier is connected with the motor shaft by the combining sleeve; and when the motor fails and stops running, the temperature of a system cooling liquid of the engine is increased, the combining sleeve moves into a locking ring under the effect of the driving device, and connection between the planetary carrier and the motor shaft is switched off. The planetary gear type water pump motor shaft connecting device has the beneficial effects that the design is reasonable, in an aftercooling process of the engine, once the motor of a water pump fails, connection between the motor and the planetary gear carrier can be switched off, and the engine drives the water pump to continue running normally.
Description
technical field [0001] The invention relates to a planetary gear water pump, in particular to a planetary gear water pump motor shaft connection device, which belongs to the technical field of automobile engine manufacturing. Background technique [0002] Mechanical water pumps or electronic water pumps are widely used in the water circulation system of automobile engines. The traditional mechanical water pump is directly connected to the crankshaft of the engine through a belt. The flow rate of the water pump is determined by the speed of the engine, while the flow rate of the mechanical water pump is designed according to the maximum heat dissipation required by the engine. When the engine is working normally, the speed is high, so the water pump If the flow rate is too large, the engine is easily overcooled, and the mechanical water pump cannot adjust the flow rate of the water pump according to the engine working conditions. Since the power of the mechanical water pump ...
