Detailed description of the invention
First, it should be noted that, to illustrate the composition structure of antitorque suspending apparatus of the present invention, driving engine and automobile, feature and advantage by way of example below, but all descriptions are only used to be described, and they should be interpreted as any restriction is formed to the present invention.In addition, described in each embodiment mentioned by this paper or implicit any single technical characteristic, or be shown or implicit any single technical characteristic in the drawings and in which, still can between these technical characteristics (or its equivalent), proceed combination in any or delete, thus obtain other embodiments of the present invention more that may directly do not mention in this article.
Refer to Fig. 1, it illustrate schematically the arrangement structure of antitorque suspending apparatus of the present invention on the whole.This antitorque suspending apparatus is installed between driving engine (i.e. dynamic assembly) and vehicle frame, and is made up of parts such as housing 1, end cap 2, piston sheet 3, connecting rod 4, first elastic element 5 and the second elastic elements 6.It should be noted that, in order to more clearly show the annexation of each parts, not drawing driving engine and vehicle frame in the drawings.First by this Fig. 1 and simultaneously composition graphs 2 to Fig. 5 comes that the present invention is described in detail below.
As shown in Figures 1 and 2, housing 1 constitutes the main body of antitorque suspending apparatus, it provides the inner space holding miscellaneous part.Therefore housing 1 haply cylindrically, and has circular cross section.In one end of this housing 1, housing 1 inside is closed by the end cap 2 suitable with it by fit on, and end cap 2 can be fixed on housing 1 by fasteners such as bolts.Piston sheet 3 is arranged on the inside of housing 1, and can move in the inside of housing 1.It is pointed out that arranging piston sheet 3 in the inside of housing 1 is that therefore its cross sectional shape is identical with the cross-sectional plane of the inside of housing 1 rounded in order to the internal insulation of the housing 1 by sealing becomes disconnected first cavity and the second cavity each other.
Connecting rod 4 is the elements driving piston sheet 3 movement, and its one end is fixed on piston sheet 3 by fasteners 7 such as such as bolts, and the other end is connected with driving engine through end cap 2.By adjusting the size of connecting rod, realize the connection with different dynamic assembly.Preferably, one end that connecting rod 4 is connected with piston sheet is positioned at the center position of piston sheet 3.
In antitorque suspending apparatus of the present invention, first elastic element 5 and the second elastic element 6 are important component parts, the basic function of antitorque suspending apparatus is finally achieved just, below by the concrete structure by they are described in conjunction with above-described embodiment by the relative motion between them.First elastic element 5 is arranged in the first cavity, and its one end is against the bottom of housing 1, and the other end is against piston sheet 3; And the second elastic element 6 is arranged in the second cavity, its one end abutment end lid 2, and the other end is against piston sheet 3 (when the end of connecting rod 4 is designed to have large-size as shown in Figure 1, the other end of the second elastic element 6 can directly against the end of connecting rod 4).Can understand, piston sheet 3 can move by fast reciprocating under the promotion of connecting rod 4 in housing 1, thus the volume of air in the first cavity and the second cavity is alternately changed.Antitorque suspending apparatus of the present invention externally shows larger damping by the Fast Compression to air, and therefore its role in absorption and attenuate shock load is obviously.
In this preferred embodiment, evenly swing at the within of housing 1 to make the piston sheet 3 in antitorque suspending apparatus, first elastic element 5 can be designed to the identical parts of structure (such as Compress Spring etc.) with the second elastic element 6, and its range in stiffness is preferably between 50N/mm to 400N/mm.Certainly, be suitable different user demands, the first elastic element 5 and the second elastic element 6 also can be configured to shape not of uniform size.
As an example, housing 1 is provided with alternatively two mounting brackets 8, and mounting bracket 8 can be arranged symmetrically in the both sides of housing 1, to be firmly arranged on vehicle frame by housing 1, as in Figure 3-5.The housing of this antitorque suspending apparatus can adopt other shape, such as square etc., by adjusting size, the size and shape of housing, thus realizes the coupling from different vehicle frame.Certainly, the piston sheet be provided at its inner portion also must have cross-sectional plane same or analogous with the internal cross section of housing.It should be noted that, adjust seal degree, i.e. the size of damping by the outside dimension adjusting piston sheet.In addition, if piston sheet weares and teares excessive in the course of the work, or the first elastic element and the second elastic element rupture, and can carry out separately the replacing of sub-part, and without the need to changing whole antitorque suspending apparatus, thus effectively reduce the maintenance cost of antitorque suspending apparatus.
In sum, antitorque suspending apparatus of the present invention have structure simple, be easy to manufacture and the advantage such as maintenance.Under idling and general driving cycles, dynamic assembly output torque is relatively steady, and connecting rod and the stressed generation translation of piston sheet, the first elastic element or the second elastic element replace forced compression and externally provide antagonistic force, to control the motion of dynamic assembly.During at start and stop function operation or at gearbox shifting, the change of dynamic assembly output torque is very fast, thus produces car load and obviously impacts.Now promote piston sheet quick travel by connecting rod, can by air compressing in the annular seal space in housing, antitorque suspending apparatus externally shows larger damping in the process, and can effectively absorb and decay the impact load of dynamic assembly to car load, improves the driving ride comfort of car load.Therefore advise arranging this antitorque suspending apparatus within the engine, and apply the driving engine being provided with this antitorque suspending apparatus in the car, to obtain above-mentioned advantage.
The specific embodiment more than enumerated set forth in detail antitorque suspending apparatus of the present invention, is provided with the driving engine of this antitorque suspending apparatus, and be configured with the automobile of this driving engine, this example is only for principle of the present invention and embodiment thereof are described, but not limitation of the present invention, without departing from the spirit and scope of the present invention, those of ordinary skill in the art can also make various distortion and improvement.Therefore, all equivalent technical schemes all should belong to category of the present invention also by every claim of the present invention is limited.
