Description
Technical Field
The utility model relates to a brake power unit for a new energy electric automobile.
Background
With the popularization of new energy electric vehicles, more and more problems are being exposed to the application of the traditional hydraulic braking system on the electric vehicles. The traditional hydraulic braking system is complex in structure, brake oil needs to be replaced regularly, and development of new energy electric automobiles is severely restricted.
Disclosure of Invention
The utility model aims to provide a brake power unit for a new energy electric automobile, which has the advantages of compact structure, convenience in use and high safety.
The brake power unit for the new energy electric automobile comprises a cover body, a motor shield, a torque motor, a shell, a screw rod nut and a screw rod, wherein the inner cavity of the motor shield is communicated with the inner cavity of the shell and is connected with the inner cavity of the shell through a bolt; the shell is internally provided with an electromagnet, a ratchet wheel and a pawl which are matched with each other, the ratchet wheel is sleeved on the screw rod and is connected through a flat key, and the electromagnet is connected with the pawl and controls the pawl to rotate.
The brake power unit for the new energy electric automobile adopts the working principle that vehicle-mounted 12V/24V/48V direct current is used as a power supply, a direct current torque motor is used as a power source to drive the adapter, the adapter drives the screw rod through the flat key, and the screw rod nut converts the rotary motion of the screw rod into linear motion, so that the clamping and releasing functions of the brake are realized. Meanwhile, the ratchet wheel device connected to the screw rod realizes locking and releasing of the pawl and the ratchet wheel through retraction and release of the electromagnet, so that the parking function is realized.
The brake power unit for the new energy electric automobile has a compact structure, can meet the installation requirement in a limited space, and has the characteristics of convenience in operation, high safety and the like.
