Description
Technical field
The invention belongs to automobile technical field, and in particular to a kind of be arranged on power assembly is used to improve collision performance
Structure.
Background technology
The security performance of automobile is more and more important at present, and many vehicles are wanted in the tight head-on crash test of increasingly increased
The collision result got well is also more and more difficult.The antitorque suspension of most of vehicle is arranged separately in engine side or gearbox
Side, it will cause only have a kind of unilateral structure to associate between power assembly and front rack.Collided during head-on crash
Energy can not be delivered to front rack (chassis) from engine side and gear-box side simultaneously.Such as the antitorque suspension installation of certain vehicle
In engine side, when tackling C-NCAP collisions " 40% biasing is touched " project (collision area is left side headstock), such a general arrangement
Design has greater risk in terms of the key parameters such as front wall intrusion volume, therefore is to car in most cases to improve collision performance
The self structures such as body front longitudinal, energy-absorbing are fast, collision prevention girders, dynamic assembly suspension carry out larger reinforcement, but this reinforcement can be brought
The substantial increase of weight, cost.
The content of the invention
The purpose of the present invention is exactly insufficient existing for above-mentioned background technology in order to solve, there is provided one kind is arranged in power assembly
The upper structure for being used to improve collision performance.
The technical solution adopted by the present invention is：A kind of be arranged in is used for the structure for improving collision performance, bag on power assembly
Gearbox, front rack and Impactor are included, the Impactor is fixed on gearbox between gearbox and front rack.
Further, gap is provided between the Impactor and front rack.
Further, the Impactor includes the mounting bracket being fixed together and collision support, and mounting bracket is fixed
In on gearbox, the collision support includes three sections, and interlude protrudes from two sections of left and right and is fixedly connected with mounting bracket bottom, institute
It is platy structure to state interlude, two sections of left and right and the linkage section between two sections of interlude and left and right.
The present invention collides support in the setting of gearbox and front rack, forms stealthy connect passage, the structure in collision
Fully contacted with front rack, collision energy is delivered to front rack from gearbox, at the same collide support itself can also by burst
Contracting absorbs energy, constructs a kind of brand-new " vehicle body-gearbox-front rack " energy transmission path, " 40% biasing is touched " etc.
Transmitted in collision process, absorb big energy, reduce intrusion volume of the power assembly to front panel, lift vehicle safety performance；Separately
Outside, during 100% head-on crash, due to be provided simultaneously with gearbox, engine both ends energy transmission path.Vehicle safety
Performance greatly improves.The collision support need not change body structure, be installed merely with the hole position on gearbox, installation
It is simple in construction, cost is cheap, technical risk is small, and in collision process absorb energy positive effect, effectively lift vehicle safety
Performance.

Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, is easy to that this hair is well understood
It is bright, but they do not form to the present invention and limited.
As Figure 1-5, the present invention includes gearbox 1, front rack 3 and Impactor 5, and the Impactor 5 is fixed on speed change
On case 1 between gearbox 1 and front rack 3, gap is reserved between Impactor 5 and front rack 3, this gap can ensure normally
The shake of gearbox 1 will not be interfered with front rack 3 during use.The present invention can also include engine 2 and antitorque suspension 4, antitorque outstanding
4 are put to be fixed between engine 2 and front rack 3.The Impactor 5 of the present invention is fixed on gearbox 1, is based on antitorque suspension 4
The vehicle being fixed between engine 2 and front rack 3.But when being fixed on the vehicle on gearbox for antitorque suspension, this implementation
Impactor in example, which can also design, to be fixed on the engine, makes it when 40% biasing is touched with 100% head-on crash, Dou Nenggai
Kind collision performance.
Impactor 5 includes the mounting bracket 6 being fixed together and collision support 8, and mounting bracket 6 is fixed on gearbox 1.
The mounting hole for coordinating with gearbox 1 and the bolt hole for being connected with collision support 8, installation branch are provided with mounting bracket 6
Frame 6 is machining casting, simple in construction, firmly install；Collision support 8 is then bent into three sections by steel plate or other platy structures,
Section, interlude 81 protrude from left and right and are fixedly connected with the bottom of mounting bracket 6 by bolt 7 for two section 83 two-by-two for interlude and left and right,
The interlude 81, two section 83 of left and right and the linkage section 82 between two sections of interlude and left and right are platy structure, and technique is simple
List, energy-absorbing effect are good, and interlude 81, two section 83 of left and right and linkage section 82 form " several " character form structure, " several " character form structure
Opening alignment front rack 3, self structure crumple deformation is to absorb energy under very strong energy impact effect.
The present invention forms stealthy connect passage in the setting Impactor 5 of gearbox 1 and front rack 3, first will installation during installation
Support 6, collision support 8 are installed together by bolt 7, then Impactor 5 are arranged on gearbox 1, the gearbox 1 in collision
Fully contacted with front rack 3 by Impactor 5, collision energy is delivered to front rack 3 from gearbox 1, while collide support 8 certainly
Body absorbs energy also by crumple.The collision support need not change body structure, be installed merely with the hole position on gearbox
, mounting structure is simple, cost is cheap, technical risk is small, and energy positive effect is absorbed in collision process, effectively lifting
Vehicle safety performance.
The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
