Description
Technical Field
The invention relates to the technical field of vehicle air-conditioning compressors, in particular to a speed reduction clutch mechanism and a motor transmission device of a charged double-drive vehicle air-conditioning compressor.
Background
In conventional automobiles, the air conditioning compressor is driven by a pulley connected to the internal combustion engine, and an open-type piston or scroll compressor is often employed. In this case, the rotation speed of the compressor is determined by the rotation speed of the engine, and thus has a characteristic that the speed ratio is fixed. In a pure electric vehicle, a high-voltage (about 300V) electric compressor is generally used as a main flow configuration, and a motor and a compressor are generally made into a semi-closed form. In this case, the power of the compressor is completely controlled by the motor. In a hybrid electric vehicle, particularly in various hybrid electric vehicles with strong mixing or weak mixing, any two compressors are not optimal in configuration, so that the problem of coordination between functions and efficiency cannot be solved, and particularly, the operation of an air-conditioning compressor can be realized when a truck is in rest, which is a technical key for a person skilled in the art to pay labor to promote.
2018112154475, separable and combinable air compressor transmission for an engine and a transmission method thereof, comprising: an air compressor gear arrangement and an air compressor arrangement; a bearing seat in the gear device of the air compressor is arranged on a gear chamber of the engine, a needle bearing and a ball bearing are arranged in an inner hole of the bearing seat, the gear of the air compressor is arranged in inner holes of the needle bearing and the ball bearing, an inner ring of the needle bearing is tightly attached to the end surface of the gear of the air compressor, a spacer bush is arranged between the needle bearing and the ball bearing, and a rolling bearing is arranged at the rear end of the inner ring of the ball bearing by a locking washer and a locking nut; the rear end of the air compressor gear is provided with cross teeth; the rear end of the bearing seat is connected with an air compressor device. When the air compressor is needed to be used, the air compressor can be operated, and when the air compressor is not needed to be used, the air compressor can be stopped, so that the service life of the air compressor is prolonged, the fuel consumption of an engine is reduced, the stop and the operation of the air compressor are effectively controlled, and the structural design is completely different from the design principle of the scheme.
And as the existing motor rotor and a transmission shaft directly output torque to generate power through a key slot or interference fit. The front end of the transmission shaft is also provided with an acceleration and deceleration mechanism, so that the rotating speed output by the motor is reduced, and the torque is increased. The disadvantages are as follows: the transmission shaft of the existing motor is solid or hollow, and the middle position of the transmission shaft is not utilized. The torque is directly output by a transmission shaft of a motor rotor, and the effect of reducing speed and increasing torque is not achieved; the output torque after passing through the speed reducing mechanism has the functions of reducing speed and increasing torque, but the motor auxiliary transmission shaft and the power output main transmission shaft are separated and are not on the same shaft, and the main transmission shaft does not support the auxiliary transmission shaft and can not realize the clutch function while the speed reducing mechanism works.
Therefore, the technical personnel in the field should solve the problems in time and provide more choices for the market.
