Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with accompanying drawing, specific embodiment is described in detail.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of apparatus of the present invention embodiment, as shown in Figure 1, embodiments provide a kind of device for controlling wheel hub and driving system deciliter, the axle drive shaft 9 of described driving system is connected with wheel hub 1 and drive hub 1 rotates, and described device comprises: link, function unit, clutch plate 3, driving disc spacing pressing 5 and cover plate 8;
The axial one end of described link is fixedly connected with wheel hub 1 by bolt, and described clutch plate 3 and driving disc spacing pressing 5 can be arranged on link inside axially slidably, described clutch plate 3 and driving disc spacing pressing 5 dead in line; Described cover plate 8 is fixedly installed on the axial other end end of link, and one is that clutch plate 3 and driving disc spacing pressing 5 are limited in link inside, also plays the effect of support and firm axle drive shaft 9 in addition; Described axle drive shaft 9 drives driving disc spacing pressing 5 to rotate through cover plate 8 and driving disc spacing pressing 5 successively, and described driving disc spacing pressing 5 drives clutch plate 3 to rotate, described clutch plate 3 is connected also drive hub 1 and rotates with the axle of wheel hub 1; The axle of above-mentioned wheel hub 1 and clutch plate 3 and axle drive shaft 9 all adopt splined mode with driving disc spacing pressing 5, because groove is more shallow, tooth root place stress is concentrated less, the strength reduction of axle and hub is less, the more important thing is that the guidance quality of splined is good, wheel hub is separated with the process combined with axle drive shaft more laborsaving.
Described function unit is arranged between the clutch plate 3 of link inside and driving disc spacing pressing 5, for controlling sliding axially of clutch plate 3 and driving disc spacing pressing 5, also just can control clutch plate 3 and combining with driving disc spacing pressing 5 or be separated;
Described function unit comprises: compact heap 6, electromagnet 4 and pull back spring 7;
Described compact heap 6 can be arranged between driving disc spacing pressing 5 and cover plate 8 axially slidably, and described link is provided with electromagnet 4 near between one end of wheel hub 1 and compact heap 6, is connected with pull back spring 7 between described compact heap 6 and cover plate 8.
Above-mentioned function unit is not limited to above-mentioned a kind of form, can also have multiple, such as, still adopt friction lining type of drive between driving disc spacing pressing 5 and clutch plate 3, but their separation no longer adopts the array mode of electromagnet 4 and pull back spring 7 with combination; Corresponding mechanical component can be designed be connected with clutch plate 3 with driving disc spacing pressing 5 respectively, thus control driving disc spacing pressing 5 and be separated or combine etc. mode by controlling the motion of mechanical component with clutch plate 3, repeat no more herein.
Above-mentionedly be arranged on compact heap 6 between driving disc spacing pressing 5 and cover plate 8 and can be directly enclosed within axle drive shaft 9, it is axle sleeve driving disc spacing pressing 5 being designed to similar notch cuttype in this example, in the two poles of the earth stairstepping, one end external diameter near clutch plate 3 is greater than another part external diameter, and compact heap 6 is arranged on the little outer radius of driving disc spacing pressing 5, and slide axially, equally, compact heap 6 and cover plate 8 are fixedly installed on pull back spring 7 two ends.
In a preferred embodiment of apparatus of the present invention, electromagnet 4 is provided with between the inner end surface of described link near one end of wheel hub 1 and the end face of compact heap 6 one end, axial notch is offered in described link inside, in this example, link internal symmetry offers two grooves, and electromagnet 4 is arranged in groove; Described electromagnet 4 one end is fixed on the inner end surface of described link one end.
Described compact heap 6 is provided with orienting lug that is identical with described groove shapes and the projection that position is corresponding, namely two orienting lugs are symmetrically arranged with, described each orienting lug and cover plate 8 are fixedly installed on pull back spring 7 two ends, and the number of pull back spring 7 and elasticity can be determined according to the friction force size between the weight of compact heap 6, compact heap 6 and axle drive shaft 9 or driving disc spacing pressing 5.
Described driving disc spacing pressing 5 can adopt various ways to drive clutch plate 3, such as gear transmission or friction lining type of belt drive etc., this example preferably driving disc spacing pressing 5 is equipped with friction lining with the contact jaw of clutch plate 3, carry out transferring power by the friction of friction lining, make to control being separated and combining more quick and precisely of wheel hub and axle drive shaft.
In addition, the link of apparatus of the present invention can be make according to the situation of wheel hub 1 with axle drive shaft 9 and its internal piloting parts, and planform can be varied, as long as can meet the demands; Consider cost-saving in this example, the object such as to make rational use of resources adopts steering swivel 2 to machine, steering swivel 2 does not play steering-effecting herein, only as the link between wheel hub 1 and axle drive shaft 9, and arranges corresponding function unit and other component therein.
Basic functional principle of the present invention is as follows:
Wheel hub 1 and axle drive shaft 9 released state: as shown in Figure 2, when electromagnet 4 is energized, attraction compact heap 6 is slided left, compact heap 6 promotes driving disc spacing pressing 5 and slides left, and the friction lining of driving disc spacing pressing 5 contacts with the friction lining of clutch plate 3 and finally compresses, and realizes power connect by friction.
Wheel hub 1 and axle drive shaft 9 bonding state: as shown in Figure 3, lose magnetic force when electromagnet 4 power-off, compact heap 6 slides to the right because of the elastic force of pull back spring 7, driving disc spacing pressing 5 loses pressure to be separated with compact heap 6, power disconnects, and during wheel movement, axle drive shaft 9 no longer follows rotation, thus saves the energy.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
