Abstract
The utility model relates to an automatic parking braking device for a car, which comprises a braking disc and a parking mechanism. The parking mechanism is composed of an electric magnet, wherein, an electrical source positive and negative electrodes of which are connected in the car and are fixed on a steering column, a friction plate which is fixedly connected with the front end of an electromagnet core of the electric magnet and a brake piece which is fixed on the lateral face in the braking disc. The friction plate which is fixedly connected with the front end of an electromagnet core is opposite to the brake piece which is fixed on the lateral face in the braking disc, and the friction plate is respectively contacted and disengaged with the brake piece when the electromagnet core is protruded and retracted. The utility model has the advantages of simple structure and convenient use and belongs to a device which can realize automatic parking braking without routine adjustment of the parking mechanism.
Description
The utility model relates to a kind of automobile automatic parking brake device, particularly is applicable to the automatic parking brake device of car.
At present, when the parking of automobile braking during standstill, the braking during standstill method of operation that adopts is to pull braking during standstill bar or foot-treadle, one end is linked to each other with braking during standstill bar or stretcher, the other end is tightened up with the cable wire that the ratchet that is used for brake wheel links to each other, wheel can not be rotated, realize braking during standstill.The weak point of above-mentioned holding brake device is that phenomenon can appear drawing in cable wire in actual use, influences the effect of braking during standstill, so need artificially holding brake device regularly to be adjusted.
The purpose of this utility model provides a kind of regular adjustment, easy to use and can realize the device of automatic parking brake that do not need.
The purpose of this utility model is achieved in that it comprises brake disc and halting mechanism, this halting mechanism by with car in the power supply positive and negative electrode join and be fixed on electromagnet on the Steering gear, be fixed in the friction lining of electromagnetic core front end of electromagnet and the brake plate that is fixed on the brake disc medial surface constitutes; The friction lining that is fixed in the electromagnetic core front end is relative with the brake plate that is fixed on the brake disc medial surface, and electromagnetic core stretches out, when withdrawing, friction lining respectively with brake plate closed contact, disengaging.
Adopt said structure, when parking of automobile kills engine, the electromagnet outage, electromagnetic core drives friction lining that is fixed in the electromagnetic core front end and the brake plate closed contact that is fixed in the brake disc medial surface, under the effect of friction force under the effect of pull back spring restoring force, brake disc can not be rotated, thereby wheel can not be moved, because the switching electricity of electromagnet can be by engine ignition switch or the control of Parking switch, so whole braking during standstill process can be finished automatically and be easy to use.
The above-mentioned friction lining that is fixed in the electromagnetic core front end is shaped as fan-shaped, and contacted of friction lining and brake plate are provided with the zig-zag projection, and the brake plate that is fixed on the brake disc medial surface is shaped as annular arrangement, and the outside face of brake plate is provided with latticed line shape projection.After adopting this structure, the electromagnet outage, fan-shaped friction lining and annular arrangement brake plate closed contact in the cavity that the latticed line shape that makes zig-zag projection on friction lining and the brake plate phase-contact surface insert the brake plate outside face convexes to form, make the braking during standstill effect better.
The utility model has the advantages that: easy to use, simple in structure, realize the automatic parking brake process and do not need regular adjustment by control engine ignition switch or Parking switch, just can reach the actv. braking during standstill.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model automobile automatic parking brake device.
Fig. 2 is the cutaway view along A-A line among Fig. 1.
Fig. 3 is schematic circuit diagram of the present utility model.
Fig. 4 is the structural representation of the utility model electromagnet.
Show as Fig. 1, the utility model automobile automatic parking brake device have with car in the power supply positive and negative electrode join and be welded on electromagnet 2 on the Steering gear 1 of brake disc 3 medial surfaces one side, by the iron annular arrangement brake plate 5 (as Fig. 2 show) of screw retention on brake disc 3 medial surfaces, be welded on the iron fan-shaped friction lining 4 (showing) of the electromagnetic core 2-1 front end of electromagnet 2 as Fig. 4.On iron annular arrangement brake plate 5 outside faces of brake disc 3 medial surfaces, be cast with latticed line shape projection (showing) by screw retention, be cast with zig-zag projection (showing) on the iron fan-shaped friction lining 4 of the electromagnetic core 2-1 front end of electromagnet 2 welding and the face that iron annular arrangement brake plate 5 contacts as Fig. 4 as Fig. 2.
Show as Fig. 3, power supply 3-4, automotive engine switch 3-1, electromagnet 2 series connection in the car, in parallel with electromagnet 2 two ends respectively by the circuit series two ends that Parking switch 3-2 and Warning light 3-3 form, the resistance of Warning light 3-3 will be far smaller than the resistance of electromagnet 2.When parking of automobile, switch 3-1 (promptly disconnecting) kills engine, make electromagnet 2 be in off-position, under the elastic-restoring force effect of pull back spring 2-3, make fan-shaped friction lining 4 motions (showing) that are welded on electromagnetic core 2-1 front end as Fig. 4, and with annular arrangement brake plate 5 closed contacts (showing) that are fixed on brake disc 3 medial surfaces as Fig. 2, at this moment fan-shaped friction lining 4 is gone up the zig-zag projection with 5 contacted of brake plates and is inserted in the cavity that latticed line shape convexes to form on annular arrangement brake plate 5 outside faces that are fixed on brake disc 3 medial surfaces, brake disc 3 can not be rotated, thereby wheel can not be moved (showing as Fig. 2).As closed motor switch 3-1, electromagnet 2 energisings, electromagnetic core 2-1 is under the electromagnetic attraction effect of magnet coil 2-2, drive fan-shaped friction lining 4 with its front end welding and overcome the elastic-restoring force of pull back spring 2-3 and move (showing) as Fig. 4, fan-shaped friction lining 4 and the annular arrangement brake plate 5 that is fixed on brake disc 3 medial surfaces are broken away from, and the braking during standstill state is removed.But in temporary transient parking, do not need to kill engine and when needing braking during standstill, can near the Parking switch 3-2 closure of car gauge panel will be positioned at, Warning light 3-3 is bright, prompting driver vehicle is in the braking during standstill state, because the resistance of Warning light 3-3 is far smaller than the resistance of electromagnet 2, thereby makes electromagnet 2 by short circuit, make electromagnet 2 outages equally, realize braking during standstill.When not needing braking during standstill, only need to disconnect Parking switch 3-2, Warning light 3-3 extinguishes, and vehicle braking during standstill state is removed.
Because the utility model is realized the releasing or the execution of braking during standstill state by the switching electricity of electromagnet, realized control automatically effectively, and do not needed holding brake device is regularly adjusted and simple in structure automobile parking braking.
