Description
Technical field
The utility model relates to a kind of vehicle electromechanical drg.
Background technology
Along with electronics technology and development of internet technology, more efficient, energy-conservation line traffic control technology has appearred.Joint line control techniques and brake system of car and the line control brake system that forms, it is a kind of later-model electro-mechanical system, consequent electric mechanical braking device is used for service brake, have energy-conserving and environment-protective, portable good, be convenient to advantages such as integrated control, dependable performance, the electric mechanical braking device makes conventional hydraulic or compression air brake power element into electric driving element, has solved long, the problems such as valve element is many, reaction is slow, poor stability of brake piping that the orthodox car brake system exists.But existing electric mechanical braking device still need cooperate and adopt the drag-line handbrake mechanism when braking during standstill, and complexity is installed, and take up room, and the drag-line handbrake mechanism is safeguarded difficulty.
The utility model content
Goal of the invention of the present utility model is to provide a kind of vehicle electromechanical drg, can either realize that service brake can realize braking during standstill again.
Realize the technical scheme of the present utility model purpose:
A kind of vehicle electromechanical drg, comprise motor, brake strip, brake disc, it is characterized in that: the nut that is driven through transmission device by motor is arranged at the inboard of rotor, is provided with the threaded mandrel that matches with it in the nut, and the end of threaded mandrel connects brake strip; Be fixed with ratchet on the outer end of nut, also be provided with the unidirectional locating dowel pin that can brake ratchet, the end of unidirectional locating dowel pin is connected with the armature of relay.
Ratchet is positioned at casing, and unidirectional locating dowel pin one end is positioned at casing and matches with ratchet, and the other end is positioned at outside the casing and is connected with the armature of relay, and unidirectional locating dowel pin is set with retracing spring.
Be fixed with sun wheel on the motor power output shaft, be connected to pinion carrier with sun wheel ingear satellite gear, pinion carrier and nut are fixed.
Be provided with ball between threaded mandrel and the nut.
The beneficial effect that the utlity model has:
The utility model has been realized the service brake and the braking during standstill integrated design of electric mechanical braking device, wherein ratchet, unidirectional locating dowel pin structure play the parking-brake action of parking brake, because the end of unidirectional locating dowel pin is connected with the armature of relay, therefore, the Parking button in the car can pass through the circuit control relay, realizes a key braking during standstill, cancelled existing drag-line handbrake mechanism, install simply, be easy to safeguard, and can effectively save the space.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model automobile parking braking part.
The specific embodiment
As shown in Figure 1, the electric mechanical braking device comprises motor, brake strip 1, brake disc 2, and this is a prior art.The nut 5 that is driven through transmission device by motor is arranged at the inboard of rotor 7, is provided with the threaded mandrel 3 that matches with it in the nut, is provided with ball 4 between threaded mandrel 3 and the nut 5, and the end of threaded mandrel connects brake strip 1; Be fixed with sun wheel on the motor power output shaft 6, be connected to pinion carrier 9 with sun wheel ingear satellite gear 8, pinion carrier and nut 5 are fixed by spline.
As shown in Figure 1 and Figure 2, be fixed with ratchet 10 on the outer end of nut 5, also be provided with the unidirectional locating dowel pin 12 that to brake ratchet, ratchet 10 is positioned at casing 11, unidirectional locating dowel pin 12 1 ends are positioned at casing and match with ratchet, the other end is positioned at outside the casing and is connected with the armature of relay 14, and unidirectional locating dowel pin 12 is set with retracing spring 13.
During service brake, relay 14 work, unidirectional locating dowel pin 12 is unclamped with ratchet 10, and the rotor 7 of motor rotates, and drives motor power output shaft 6 and rotates, thereby drive satellite gear 8 rotations, by on the pinion carrier 9 moment being passed on the nut 5, nut 5 rotations promote threaded mandrel 3 and carry out feed motion, eliminate the gap between brake disc 2 and the brake strip 1, the gripping power that generation is used to brake is realized service brake.
During braking during standstill, by the Parking button in getting off, this moment, relay 14 was not worked, and motor just changes.5 rotations of driven by motor nut, the ratchet 10 on the nut 5 rotates thereupon, and unidirectional locating dowel pin 12 rollbacks are let pass, simultaneously, brake disc 2 clamps with brake strip 1 under the effect of threaded mandrel 3, and is last, unidirectional locating dowel pin 12 resets under the effect of retracing spring, blocks ratchet, realizes braking during standstill.When needs are removed braking during standstill, unclamp the Parking button in the car, relay 14 work this moment, motor counter-rotating.Relay 14 work make unidirectional locating dowel pin 12 unclamp with ratchet 10, and the motor counter-rotating makes brake disc 2 separate with brake strip 1, removes braking during standstill.After removing braking during standstill, relay 14 quits work, and unidirectional locating dowel pin 12 resets under the effect of retracing spring, blocks ratchet.Aforesaid ratchet 10, unidirectional locating dowel pin 12 structures play the parking-brake action of parking brake, because the end of unidirectional locating dowel pin 12 is connected with the armature of relay 14, therefore, the Parking button in the car can be realized a key braking during standstill by circuit.
