Abstract
Disclosed is a collapsing absorbing energy type auxiliary frame, which is characterized by comprising a left stringer welding assembly, a right stringer welding assembly, a front beam welding assembly and a rear beam welding assembly, two mounting holes are arranged at the front and back of the left stringer welding assembly and the right stringer welding assembly respectively, and are connected with a vehicle body by bolts, the front beam welding assembly and the rear beam welding assembly are welded on stringers, and a truss structure is formed by four stringers. The utility model has better stability and strength, and can collapse automatically when impact takes place, thereby greatly absorbing impact energy.
Description
Technical field
The utility model belongs to the technical field of the subframe of vehicle chassis suspension system, particularly a kind of crumple energy-absorption type subframe.
Background technology
We know that traditional self-supporting body that does not have subframe, its suspension are directly to link to each other with the vehicle body steel plate.Therefore the fore suspension and rear suspension assembly all is a loose mail, and non-integral.
Nowadays, subframe has become the indispensable part of chassis of the minitype automobile suspension system development and Design, but it is finished under the prerequisite of basic function, brings into play bigger potential, improve safety and road-holding property that car load travels, this is individual very good problem to study.
We analyze and have contrasted a large amount of vehicles, sum up the minicar of finding in the market, its subframe adopts the pipe girder construction mostly---and tubular crossbeam and angle bar frame by two ends simmering and bending are welded, bolt together between support and the vehicle body, crossbeam transmits the road surface to vehicle body and acts on the power and the moment of tire, and is supporting deflector and Panhard rod.The subframe of this structure, its advantage is: simple in structure, the processing and manufacturing cost is low; Shortcoming is: when automobile bumps, and substantially without any energy-absorbing design and at the safety method of chaufeur.
Summary of the invention:
The purpose of this utility model is to provide a kind of crumple energy-absorption type subframe.Fore suspension and rear suspension is assembled on the subframe, constitutes an integral body; Rigidity and vibration isolation ability have been guaranteed.
The technical solution of the utility model is achieved in that
Crumple energy-absorption type subframe, it is characterized by: it is made up of left longeron welding assembly, right vertical beam welding assembly, front cross rail welding assembly, after cross member welding assembly, before and after left side longeron welding assembly, the right vertical beam welding assembly two mounting holes are arranged respectively, with vehicle body with bolted connection, front cross rail welding assembly, after cross member welding assembly are welded on the longeron, and four beams have constituted a truss structure each other.
It is better to the utlity model has stability and intensity, and automatic buckling when bumping greatly absorbs the collision impact energy certainly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is side projection figure of the present utility model.
Fig. 3 is a local structure enlarged drawing of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, crumple energy-absorption type subframe, it is characterized by: it is by left longeron welding assembly 1, right vertical beam welding assembly 2, front cross rail welding assembly 3, after cross member welding assembly 4 is formed, left side longeron welding assembly 1, respectively there are two mounting holes right vertical beam welding assembly 2 front and back, with vehicle body with bolted connection, front cross rail welding assembly 3, after cross member welding assembly 4 is welded on left longeron welding assembly 1 respectively, on right vertical beam welding assembly 2 front-end and back-end, front cross rail welding assembly 3, after cross member welding assembly 4 is welded on left longeron welding assembly 1, four beams have constituted a truss structure each other on the right vertical beam welding assembly 2.
As shown in Figure 2, crumple energy-absorption type subframe is characterized in that: left longeron welding assembly 1 and right vertical beam welding assembly 2 side rear and front end A-B section and E-G section inclination perk, and middle B-E section level is recessed, is " trapezoidal " structure; The axial stiffness of dogleg section A-B and E-G is littler than C-D section, and also there are the axial stiffness of Control arm lining and sleeve pipe in C, D place, so the trend that A-B section and E-G section are bent is greater than the trend that subframe integral body is crushed, α, β angle increase, " inverted trapezoidal structure " becomes " rectangular configuration ", α, β near or greater than 90 °; Work as A-B, when the E-G section bends, the also inevitable together clickwise of the assembly 3 of the front cross rail of welding welding thereon, after cross member welding assembly 4 and the steering gear bracket of installing 5 and deflector 6, steering shaft that links to each other with deflector 6 and steering handwheel will move to the direction away from him with respect to chaufeur so, thereby chaufeur are not caused the actv. injury when guaranteeing collision.
As shown in Figure 3, crumple energy-absorption type subframe is characterized in that: the top face of left longeron welding assembly 1, right vertical beam welding assembly 2 is designed the circular minor groove 7 of a platoon leader, and purpose is repeatedly energy-absorbing and distortion guiding.
