The invention provides an MGU unit of an electronic parking structure in a new energy automobile, and belongs to the technical field of automobiles. The MGU unit of the electronic parking structure inthe new energy automobile comprises a box body; a motor mounting groove is formed in one side of the interior of the box body, a motor is arranged in the motor mounting groove, a small belt wheel isfixed to an output shaft of the motor, a speed reducer mounting groove is formed in the other side of the interior of the box body, and a speed reducer is arranged in the speed reducer mounting groove; a small belt wheel is fixed to an input shaft of the motor, a large belt wheel is fixed to an input shaft of the speed reducer, the small belt wheel is connected with the large belt wheel through asynchronous belt, the containing space of the motor installation groove is larger than the size of the motor, the containing space of the speed reducer installation groove is matched with the speed reducer, and a retainer is arranged between the motor and the speed reducer and comprises a bottom plate; an arc-shaped plate perpendicular to the bottom plate is fixed to the upper portion of the bottom plate, and a connecting plate with the L-shaped section is fixed to one side of the bottom plate. According to the invention, the synchronous belt can be conveniently and accurately mounted betweenthe motor and the speed reducer.
Description
technical field [0001] The invention belongs to the technical field of automobiles, and relates to an electronic parking structure, in particular to an MGU unit of the electronic parking structure in a new energy vehicle. Background technique [0002] Electronic parking EPB (Electrical Parking Brake) refers to the technology of realizing parking brake by electronic control method, and electronic hand brake is the technology of realizing parking brake by electronic control method. The EPB system can automatically apply the parking brake after the engine is turned off. It is convenient and reliable to park, and can prevent accidental release (such as children, theft, etc.); it uses more advanced electronic control technology to replace the traditional mechanical hand brake to avoid parking. The car forgets to pull the handbrake, and the unsafe accident of forgetting to release the handbrake when starting; it can be used as a driving brake in an emergency. [0003] Because ele...
