Abstract
The utility model discloses a kind of novel rear overhangs to buffer block assembly, including buffering block assembly, the buffering block assembly includes metal base plate and rubber block, the metal base plate includes intermediate lower concave part and is extended on the horizontal connection wing plate at the intermediate lower concave part both ends, the horizontal connection wing plate is connected by the bolt being threaded through in bolt hole with vehicle frame mounting bracket, and the bolt hole includes the circular hole being opened on one of horizontal connection wing plate and the slot hole being arranged along long axis direction that is opened on another horizontal connection wing plate；The rubber block sticks in the lower surface of intermediate lower concave part by sulfuration process, offered in the middle part of rubber block with rear bridge tube through-hole disposed in parallel, rubber block bottom is the globoidal structure to connect with rear bridge tube.The utility model is simple in structure, of low cost, has the advantages that improve absorbing shock performance, limits play before and after rear axle housing to a certain extent, can significantly improve the NVH performances of vehicle.
Description
Technical field
The utility model is related to field of automobile, and block assembly is buffered more particularly, to a kind of novel rear overhang.
Background technology
With the fast development of modern automobile industry, requirement of the people to automobile comfort level is higher and higher.Carrying out vehicle
In evaluation and debugging process, in bumpy road when driving, rear axle bounce amplitude is larger, is easy to make under limiting case for discovery vehicle
It is in direct contact at rear axle and vehicle frame, causes vehicle NVH（Weigh the important indicator of car comfort）Deteriorate, generates shake, noise
The problems such as.In order to improve above-mentioned condition, developer focuses on buffering rear overhang the design of block assembly very much.Rear overhang buffers block assembly
Mechanism between vehicle frame and rear axle, can bear and transmit vertical load, for buffer, inhibit impact from road surface,
It limits the jerk value of rear axle and prevents from occurring directly to hit between metal, to improve vehicle NVH performances.
Invention content
The utility model provides a kind of novel rear overhang and buffers block assembly, it is therefore intended that solve existing rear overhang buffering block assembly because
Vehicle NVH performances are relatively low caused by there is fault of construction.
To achieve the above object, the utility model can take following technical proposals：
Novel rear overhang described in the utility model buffers block assembly, including buffering block assembly, the buffering block assembly include
Metal base plate and rubber block, the metal base plate include intermediate lower concave part and are extended on the water at the intermediate lower concave part both ends
Flushconnection wing plate, the horizontal connection wing plate are connected by the bolt being threaded through in bolt hole with vehicle frame mounting bracket, the spiral shell
Keyhole include the circular hole being opened on one of horizontal connection wing plate and be opened on another horizontal connection wing plate along length
The slot hole of axis direction setting；The rubber block sticks in the lower surface of intermediate lower concave part by sulfuration process, is opened in the middle part of rubber block
Equipped with rear bridge tube through-hole disposed in parallel, rubber block bottom is the globoidal structure to connect with rear bridge tube.
The rubber block both sides offer the deformation groove consistent with the through-hole direction.
Novel rear overhang provided by the utility model buffers block assembly, simple in structure, of low cost, and having improves bumper and absorbing shock
Performance, to a certain extent limit rear axle housing before and after play the advantages of, the NVH performances of vehicle can be significantly improved.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the using state structure diagram of the utility model.
Specific implementation mode
As shown in Figure 1, 2, novel rear overhang described in the utility model buffers block assembly, including buffering block assembly, described slow
It includes metal base plate 1 and rubber block 2 to rush block assembly.Wherein, during metal base plate 1 includes intermediate lower concave part 1.1 and is extended on
Between 1.1 both ends of lower concave part horizontal connection wing plate 1.2,1.3, horizontal connection wing plate 1.2,1.3 is by being threaded through in bolt hole
Bolt 3 is connected with vehicle frame mounting bracket 4, and above-mentioned bolt hole includes the circular hole 1.4 being opened on horizontal connection wing plate 1.2 and opens up
The slot hole 1.5 along long axis direction setting on horizontal connection wing plate 1.3；Rubber block 2 using by a large amount of data analysis with
The hollow design determined after physical varification sticks in the lower surface of intermediate lower concave part 1.1,2 middle part of rubber block by sulfuration process
Offer with 5 through-hole 2.1 disposed in parallel of rear bridge tube, 2 bottom of rubber block is 2.2 structure of cambered surface to connect with rear bridge tube 5, rubber
2 both sides of block offer the deformation groove 2.3,2.4 consistent with 2.1 direction of through-hole.The rubber block 2 not only has good mitigation punching
The performance of vibrations is hit, slowed down, the usage amount of robber materials can also be greatlyd save.
Vehicle travels on the way, when the utility model from road surface by being impacted, first, the rubber block 2 of hollow structure
Deformation is will produce, specifically：In zero load, deflection is zero, is gradually increased as load increases deflection, but load continues to increase
When being added to fully loaded extreme position, deflection speedup gradually slows down；Under different loads, the deflection of rubber block 2, speedup are different,
Therefore different traveling road conditions and vehicle condition are can adapt to, substantially improves vehicle ride comfort, improve the NVH of vehicle, reaches vehicle and set
Fixed performance objective；Secondly, 2.2 structure of cambered surface of 2 bottom of rubber block design, can increase the contact area of itself and rear bridge tube 5,
The road shocks that rear axle receives preferably are passed into buffer stopper, and limit the front and back play of rear axle to a certain extent；Again,
When rubber block 2 by rear axle impact when being reached stress ultimate deformation amount, metal base plate 1 can be by 1.5 reduction department of slot hole
The component of stress avoids the service life for being beneficial to extend the utility model using secondary damage caused by being fastenedly connected.
In conclusion the utility model is simple in structure, it is not high to save material, cost, there is good mitigation impact, slow down
Performance is shaken, the handling stability and comfort of vehicle can be effectively improved.
