Abstract
The invention discloses the fixed support that a kind of truck drive shaft shares with acoustic filter, this fixed support is integral type structure, its have be connected with engine cylinder-body the first connecting plate, for the cylindrical supporting sleeve supporting truck drive shaft and the second connecting plate being connected with acoustic filter, described first connecting plate and the second connecting plate are all connected on the outer wall of cylindrical supporting sleeve.This fixed support can save the arrangement space of engine nacelle, increases the fixing intensity of truck drive shaft and acoustic filter, simplifies assembly technology.
Description
Technical field
The present invention relates to the fixed support of auto parts and components, be specifically related to the fixed support that a kind of truck drive shaft shares with acoustic filter.
Background technology
Along with the development of engine technology, electromotor increasingly miniaturization, its structure is more and more compacter, in limited engine nacelle space, completes the layout of parts and fixes the most more and more difficult.For truck drive shaft and acoustic filter, traditional fixed form is: truck drive shaft is fixed on engine cylinder-body by a bearing, and acoustic filter is fixed on engine cylinder-body or automobile chassis by support.
There are the following problems for this fixed form:
(1) if excessive at other parts volume, and in the case of engine nacelle arrangement space is narrow and small, acoustic filter is difficult to find fixing point on engine cylinder-body, is only fixed on automobile chassis, but can affect the installation of other parts.
(2) bearing of fixed car power transmission shaft and the support of fixing acoustic filter are that two separate piece are connected on engine cylinder-body, and its intrinsic frequency of vibration is higher, and intensity is relatively low, makes NVH performance the highest.
(3) assembly technology is more complicated, relatively costly.
Summary of the invention
It is an object of the invention to provide the fixed support that a kind of truck drive shaft shares with acoustic filter, to save the arrangement space of engine nacelle, increase the fixing intensity of truck drive shaft and acoustic filter, simplify assembly technology.
The fixed support that truck drive shaft of the present invention shares with acoustic filter is integral type structure, its have be connected with engine cylinder-body the first connecting plate, for the cylindrical supporting sleeve supporting truck drive shaft and the second connecting plate being connected with acoustic filter, described first connecting plate and the second connecting plate are all connected on the outer wall of cylindrical supporting sleeve.
Further, being connected with engine cylinder-body for convenience, described first connecting plate is parallel with the axis of cylindrical supporting sleeve, and the first connecting plate is connected with the outer wall of cylindrical supporting sleeve by perpendicular reinforcement.
Further, fixing acoustic filter for convenience, described second connecting plate is L-shaped structure, and its vertical portion is vertical with the axis of cylindrical supporting sleeve；The top of the vertical portion of the second connecting plate is connected with the outer wall of cylindrical supporting sleeve, and the horizontal component of the second connecting plate is connected with the contiguous block being welded on acoustic filter.
Further, in order to make its intensity more preferable, the fixed support that described truck drive shaft and acoustic filter share uses aluminium alloy compression casting molding.
The present invention compared with prior art has the advantage that
(1) this fixed support is that truck drive shaft shares with acoustic filter, and is integral type structure, so that the layout of engine nacelle is compacter, well solves the problem that engine nacelle arrangement space is not enough.
(2) this fixed support is integral type structure, reducing eigentone, use aluminium alloy compression casting molding, its intensity increases relative to the split type of two separate piece, its reinforcement too increases certain intensity simultaneously, makes support bracket fastened NVH performance promote.
(3) this fixing rack structure is simple, after supporting truck drive shaft and fixing acoustic filter, (i.e. assembly technology is simple) easy to connect with engine cylinder-body, and cost is relatively low.
Accompanying drawing explanation
Fig. 1 is the assembling schematic diagram of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
nullThe fixed support that truck drive shaft as shown in Figure 1 and acoustic filter share is the integral structure using aluminium alloy compression casting molding，It has and is bolted the first fixing connecting plate 1 with engine cylinder-body、For supporting the cylindrical supporting sleeve 2 of truck drive shaft 5 and being bolted the second fixing connecting plate 3 with acoustic filter 6，First connecting plate 1 is parallel with the axis of cylindrical supporting sleeve 2，First connecting plate 1 is connected with the outer wall of cylindrical supporting sleeve 2 by perpendicular reinforcement 7，Second connecting plate 3 is L-shaped structure，Its vertical portion is vertical with the axis of cylindrical supporting sleeve 2，The top of the vertical portion of the second connecting plate 3 is connected with the outer wall of cylindrical supporting sleeve 2，The horizontal component of the second connecting plate 3 and the contiguous block 4 being welded on acoustic filter 6 are bolted that (contiguous block 4 is inverted U-shaped，The horizontal component of the second connecting plate 3 just top with this contiguous block 4 is bolted).
Four bolts hole are offered on first connecting plate 1, two of which spiro keyhole position is in reinforcement 7 side, two other spiro keyhole position is in reinforcement 7 opposite side, and it is symmetrical about reinforcement 7, the bearing of fixed car power transmission shaft 5 is installed in cylindrical supporting sleeve 2, offering a bolt hole respectively on four corners of the horizontal component of the second connecting plate 3, the outer tube wall of acoustic filter 6 is welded with contiguous block 4, four, the top of this contiguous block 4 offers a bolt hole on corner respectively.When assembling, first pass through four bolts and the first connecting plate 1 is fixed on engine cylinder-body；Then, by truck drive shaft 5 through cylindrical supporting sleeve 2, by bearing, truck drive shaft 5 is fixed；Finally, with four bolts, the horizontal component of the second connecting plate 3 is fixed on the top of contiguous block 4, thus acoustic filter 6 is fixed.
Claims (2)
1. the fixed support that a truck drive shaft shares with acoustic filter, it is characterized in that: this fixed support is integral type structure, it has the first connecting plate (1) being connected with engine cylinder-body, the cylindrical supporting sleeve (2) that is used for supporting truck drive shaft (5) and the second connecting plate (3) being connected with acoustic filter (6)；
Described first connecting plate (1) is parallel with the axis of cylindrical supporting sleeve (2), and the first connecting plate is connected with the outer wall of cylindrical supporting sleeve by perpendicular reinforcement (7)；
Described second connecting plate (3) is L-shaped structure, and its vertical portion is vertical with the axis of cylindrical supporting sleeve (2)；The top of the vertical portion of the second connecting plate is connected with the outer wall of cylindrical supporting sleeve, and the horizontal component of the second connecting plate is connected with the contiguous block (4) being welded on acoustic filter.
The fixed support that truck drive shaft the most according to claim 1 shares with acoustic filter, is characterized in that: this fixed support uses aluminium alloy compression casting molding.
