The specific embodiment
Core of the present invention is, a kind of check mechanism for the hybrid power bulldozer is provided, to solve the fast braking problem of bulldozer under the state of emergency.On this basis, the present invention also provides a kind of hybrid power bulldozer that comprises above-mentioned check mechanism.
Be without loss of generality, specify below in conjunction with Figure of description, be used for the specific embodiment of the check mechanism of hybrid power bulldozer among the present invention.
Seeing also Fig. 1 is the sectional view that the invention provides check mechanism the first embodiment, and Fig. 2 shows the front view of electromagnetic brake among Fig. 1, and Fig. 3 shows the left view of electromagnetic brake among Fig. 1, and Fig. 4 shows the second embodiment of check mechanism provided by the invention.
As shown in Figure 1, the check mechanism that is used for the hybrid power bulldozer that this programme provides, comprise drive motors (1), drive motors (1) has for the armature shaft (11) of outputting power with the driving vehicle wheel rotation, and this armature shaft (11) is provided with electromagnetic brake (2).
Compared with prior art, the armature shaft 11 of drive motors 1 of the present invention is provided with electromagnetic brake 2, utilize electromagnetic brake to make the quick combination of driving part and slave unit and the characteristics of separating by power on/off, shortened the bulldozer braking response time in case of emergency, thus the functional reliability and the safety that have improved bulldozer.
Armature shaft 11 has outputting power to drive the output of wheel, electromagnetic brake 2 can be arranged on this output.Also can adopt armature shaft 11 as shown in Figure 1, this armature shaft 11 has double output ends, and an output is used for driving wheel, and another output on the other side is provided with electromagnetic brake 2.
This armature shaft 11 with double output ends can be divided into electromagnetic brake 2 and wheel drive the two ends of armature shaft 11, avoided the location conflicts between the electromagnetic brake 2 and wheel drive in the assembling process.In addition, owing to also needing to be connected with wheel drive when electromagnetic brake 2 is installed, after adopting the armature shaft 11 of double output ends, the length of the output that is connected with wheel drive on the armature shaft 11 can be constant, in order to avoid increase wheel drive to the moment of the armature shaft 11 of drive motors 1, avoid causing flexural deformation or the fracture of armature shaft 11.
To sum up, adopt the armature shaft 11 with double output ends guaranteeing on the drive motors basis in 1 application life in this programme, the transmission joint design of original drive motors and wheel be need not change, thereby shortened the design cycle, reduced manufacturing cost.
As shown in Figures 2 and 3, electromagnetic brake 2 in this programme is specially dry single-disk friction-type electromagnetic brake, comprise the yoke 28 that is fixed with hot-wire coil 21, with the brake disc 22 that is connected spline housing 24 and is connected with armature shaft 11, and spline housing 24 is connected by key with armature shaft 11; Between brake disc 22 and yoke 28, be provided with armature 23, and between yoke 28 and armature 23, be provided with spring 25.And installing plate 27, armature 23 and yoke 28 are fixedly connected with by the motor casing of bolt assembly with drive motors 1 successively.Wherein, electromagnetic brake 2 is under original state, and namely under the off-position, armature 23 arranges with yoke 28 gaps, and is slidingly matched with bolt assembly.
Under the original state, coil 21 outages of electromagnetic brake 2, armature 23 is fitted with brake disc 22 under the resilient force of spring 25; Under the bulldozer normal operating conditions, coil 21 energisings of electromagnetic brake 2, armature 23 overcomes elastic force under electromagnetic force separates with brake disc 22, and this moment, brake disc 22 rotated with armature shaft 11; When bulldozer needs brake hard, coil 21 outages of electromagnetic brake 2, electromagnetic force disappears, and armature 23 returns back to original state under spring 25 resilient force, and namely armature 23 is fitted with brake disc 22, and this moment, drive motors 1 under the frictional force effect quit work.
Need to prove, the electromagnetic brake 2 in this programme has adopted dry single-disk friction-type electromagnetic brake, and the band electromagnetic brake of this structure has simple compactness, and is easy and simple to handle, the characteristics that cost is low.In addition, owing to armature 23 is acting directly on the brake disc 22 under the effect of spring force, so the reception and registration of torsion is fast, can reach easily action.Be appreciated that on the basis of satisfying braking function demand and assembly technology requirement thereof, the electromagnetic brake in this programme also can adopt dry multi-piece friction formula electromagnetic brake or Wet-type multi-disc electromagnetic brake.
Further, as shown in Figure 2, for frictional force and the abrasion resistance that increases brake disc, be provided with friction lining 26 on the rubbing surface of the brake disc 22 in this programme.Friction lining 26 on the brake disc 22 can adopt asbestos-based friction material to make, this asbestos-based friction material is to form by asbestos or with abestrine cloth, cementing agent and specialist additive hot pressing that wire strengthens, has the advantages that friction factor is large, price is low, density is little and durable.Need to prove, friction lining 26 in this programme also can adopt the non-asbestos-based friction material that the abrasion-resistances such as glass fiber, cermet are strong and contamination-free volatilizees, certainly, in the situation that satisfy the friction factor requirement, also can adopt to well known to a person skilled in the art other materials.
As previously mentioned, brake disc 22 and armature shaft 11 in this programme removably connect by spline housing 24, when brake disc 22 consumable accessorys such as grade damage, only needing to change corresponding parts gets final product, cooperate with it miscellaneous part can continue to use, thereby simplified maintenance process, also reduced maintenance cost.In addition, this programme has adopted spline joint, have stressed evenly, characteristics that supporting capacity is strong.Be appreciated that on the basis of the bonding strength that satisfies armature shaft 11 and brake disc 22 connected mode that both also can adopt interference fit, key to connect or directly weld.
Further, as shown in Figure 2, installing plate 27 on the electromagnetic brake 2 in this programme, armature 23 and yoke 28, the three removably connects by threaded components for standalone module designs again, therefore, when a certain parts need to be changed, only need be changed that module whole of changing and get final product, and are simple to operate, quick, but thereby simplify maintenance process, reduced maintenance cost.
Electromagnetic brake 2 in this programme also can oppositely be installed, and concrete structure sees also Fig. 4.Be appreciated that adopt oppositely install after, the structure of this electromagnetic brake, operating principle are identical with aforementioned mounting structure, therefore it will be understood by those skilled in the art that and do not repeat them here.
Need to prove, the working method of the electromagnetic brake in this programme is separated for switching on, the outage combination, and certainly, its working method also can adopt outage separation, energising combination.
In addition, adopt at present usually air-cooled drive motors, but this type of cooling is not suitable for work under bad environment, requires the engineering machinery such as bulldozer of long time continuous working, therefore, the drive motors 1 in this programme is specially the water-cooled magneto.
Except above-mentioned check mechanism, the present invention also provides a kind of hybrid power bulldozer, comprises above-mentioned check mechanism.Be appreciated that the basic function parts that consist of this bulldozer and operating principle and prior art are basic identical, those skilled in the art can realize fully based on prior art, therefore this paper repeats no more.
The above only is preferred embodiment of the present invention, does not consist of the restriction to protection domain of the present invention.Any any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present invention.
