Abstract
The utility model relates to the technical field of vehicle parts, in particular discloses an elastic connection structure for a primary car frame and a secondary car frame. The elastic connection structure for the primary car frame and the secondary car frame comprises a primary car frame, a secondary car frame, a car frame connection plate, a secondary car frame connection plate, a first bolt, a first nut and a spring. The primary car frame is fasteningly connected with the car frame connection plate, the secondary car frame is fixedly connected with the secondary car frame connection plate, and the secondary car frame is positioned above the primary car frame. The spring is sleeved on the first bolt, and the car frame connection plate and the secondary car frame connection plate are fixed together through the first bolt sleeved with the spring and the first nut. The elastic connection structure for the primary car frame and the secondary car frame is added with the spring with good elastic deformation performance, therefore impact force and inner stress of the secondary car frame are effectively reduced in running of vehicles, early-stage deformation and damage of the secondary car frame are avoided, use performance of the vehicle is guaranteed, safety performance of the whole vehicle is improved, and service life of the whole vehicle is prolonged.
Description
Technical field
The utility model relates to the vehicle part technical field, particularly a kind of major and minor vehicle frame elastic connection structure.
Background technology
At present, domestic vehicle main car frame is connected with subframe and mostly is being rigidly connected by the connecting panel bolt up.In vehicle ', especially for dumping car, often the impulsive force that is subjected to of subframe can't obtain buffering, stressed bigger, further increase the internal stress of subframe, cause subframe early deformation and damage to occur, influence the safe handling of user vehicle, the miscellaneous part that influences vehicle simultaneously is damaged, and then shortens the service life of car load.
The utility model content
(1) technical matters that will solve
The technical problems to be solved in the utility model provides a kind of major and minor vehicle frame elastic connection structure, because the spring that adds has elastic deformation performance preferably, make vehicle under steam, can reduce impulsive force and internal stress effectively to subframe, prevent that early deformation and damage from appearring in subframe, guarantee the vehicle operation performance, improve the safety of car load, prolong car load service life.
(2) technical scheme
In order to address the above problem, the utility model provides a kind of major and minor vehicle frame elastic connection structure, comprises main car frame, subframe, vehicle frame connecting panel, subframe connecting panel, first bolt, first nut and spring;
The described main car frame plate that connects to ground is fastenedly connected;
Described subframe is captiveed joint with the subframe connecting panel;
Described subframe be positioned at described main car frame above;
Described spring housing is on described first bolt, and first bolt and first nut that are with spring tighten together vehicle frame connecting panel and subframe connecting panel.
Further, also comprise the packing ring that is positioned at the spring below and the plane is provided for described spring.
Further, also comprise: second bolt and second nut;
The described main car frame plate that connects to ground is fastenedly connected by second bolt and second nut.
(3) beneficial effect
The major-minor vehicle frame elastic connection structure that the utility model provides, because the spring that adds has elastic deformation performance preferably, make vehicle under steam, can reduce the impulsive force and the internal stress of subframe effectively, prevent that early deformation and damage from appearring in subframe, guarantee the vehicle operation performance, improve the safety of car load, prolong car load service life.
Description of drawings
Fig. 1 is the utility model embodiment major-minor vehicle frame elastic connection structure structural representation.
Among the figure: 1, main car frame; 2, vehicle frame connecting panel; 3, subframe; 4, first nut; 5, subframe connecting panel; 6, packing ring; 7, spring; 8, first bolt; 9, second nut; 10, second bolt.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the major and minor vehicle frame elastic connection structure of the utility model embodiment comprises: main car frame 1, vehicle frame connecting panel 2, subframe 3, subframe connecting panel 5, first bolt 8, first nut 4, spring 7, second nut 9 and second bolt 10.
Wherein, main car frame 1 plate 2 that connects to ground is fastenedly connected by second bolt 10 and second nut 9.Subframe 3 is welded on the subframe connecting panel 5.This subframe 3 be positioned at main car frame 1 above.
This spring 7 is enclosed within on first bolt 8, and first bolt 8 and first nut 4 that are with spring 7 tighten together vehicle frame connecting panel 2 and subframe connecting panel 5.Wherein, this connection structure also comprises packing ring 6, and this packing ring 6 is positioned at spring 7 belows and provides the plane for spring 7.Because vehicle frame connecting panel 2 is connected with main car frame 1, subframe connecting panel 5 is connected with subframe 3, and first bolt 8 and first nut 4 tighten together vehicle frame connecting panel 2 and subframe connecting panel 5 together with spring 7, and then main car frame 1 and subframe 3 are tightened together.Because the spring 7 that adds has elastic deformation performance preferably, makes main car frame 1 become elasticity with subframe 3 by being rigidly connected and is connected.When vehicle ' was impacted and twist, spring 7 compressions and absorption were from the impulsive force and the twist angle of main car frame 1, thereby minimizing reduces the stress of subframe 3 to subframe 3 impulsive forces and distortion, prevents subframe 3 early deformations and damage.
The major and minor vehicle frame elastic connection structure that the utility model provides, because the spring that adds has elastic deformation performance preferably, make vehicle under steam, especially run into the road surface when abominable, can reduce the impulsive force and the internal stress of subframe effectively, prevent that early deformation and damage from appearring in subframe, guarantee the vehicle operation performance, improve the safety of car load, prolong car load service life.
Above embodiment only is used to illustrate the utility model; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
