Description
Technical field
The utility model relates to technical field of automobile parts, more particularly, to a kind of double drive EPB parking electric machine assembly.
Background technique
Electronic brake system (EPB:Electrical Park Brake) refers to the provisional system in driving conditions
Long when property braking function after dynamic and parking combines, and the technology of stopping brake is realized by electronic control mode.
This technology has been extended to automatic parking function AUTO HOLD from basic parking function.AUTO HOLD is automatic
The utilization of parking function technology can start corresponding automatic so that driver does not need to brake for a long time when vehicle stops
Parking function makes vehicle remain static always.When needing to release stationary state, also need to only dub throttle can release system
It is dynamic.This configuration is convenient and practical, while also can be reduced some unnecessary accidents caused by many accidents.
Currently, electronic parking (EPB) braking system, is to generate chucking power by motor clamping brake block to stop to reach control
Vehicle braking, motor release achieve the purpose that discharge parking braking.
That there are output powers is small for existing motor-driven mechanism, mounting condition is high, can not safeguard, vehicle adaptation range is narrow, makes
The deficiencies of being limited with environment.
Utility model content
In order to solve the above problem, the utility model provides the double drive that a kind of structure is simple, protective is good, applied widely
EPB parking electric machine assembly.
The technical solution adopted in the utility model is: a kind of double drive EPB parking electric machine assembly, it is characterised in that: including
Shell and lid, the shell and lid mutually snap together, and form the installation cavity of sealing；It is equipped in the installation cavity
At least a set of motor-driven mechanism, the motor-driven mechanism include motor, the motor gear that motor output rod end is set,
Reduction gear component with the duplicate gear of motor gear cooperation and with duplex-gear cooperation, the reduction gear component pass through shell
It is connected by the driving screw rod of splined shaft and clamp.
Preferably, being symmetrically arranged with the identical motor-driven mechanism of two nested structures in the installation cavity.
Preferably, the shell is equipped with the mounting hole for fixing EPB clamp.
Preferably, being equipped with gear ring between the reduction gear component and shell.
Further, it is sealed between the shell and lid by rubber mat, O-shaped seal washer and rubber plug.
The beneficial effect that the utility model obtains is: motor-driven mechanism being mounted on the sealing that shell and lid are formed and is pacified
It fills in cavity, shell and lid are all made of metal material and are made, and are connected by screw, using rubber seal, have overall structure
Anti- electromagnetic environment prevents mechanical shock, anti-muddy water dust atmosphere and has very strong weatherability；Using dismountable assembling structure,
With higher maintainability performance.The output torque of motor is after gear reduction, by splined shaft and clamp driving screw rod
Splined hole cooperate transmitting, formed tractive force, compress or release plunger, thus clamping or take-off the brake piece, structure it is simple.Pacifying
It fills and is symmetrical arranged two sets of motor-driven mechanisms in cavity, the united application of bi-motor, Double-gear mechanism is primary to input, torque times
Increase output, effectively expands use scope.
