As shown in Figure 3, described left tail walking beam installation assembly 4 is identical with the structure of right tail walking beam installation assembly 5, all includes vertical beam 41, is separately mounted to several screw shells 44 that the upper sealing plate 42 at vertical beam about 41 two ends is arranged in vertical beam 41 with lower shrouding 43 and embedding.Offering through hole in described vertical beam 41, described screw shell 44 is installed in through-holes, and described screw shell 44 is provided with internal thread.Preferably, described screw shell 44 is 3.Described screw shell 44, for left installation through hole or right installation through hole with the use of, by bolt, the two ends, left and right of walking beam assembly are detachably connected on left tail walking beam installation assembly, right tail walking beam installation assembly.The utility model removably connects with left tail walking beam installation assembly, right tail walking beam installation assembly by being designed as at the two ends, left and right of walking beam assembly, there are enough spaces to make engine push when ensure that engine assembly, improve the convenience of engine assembly.
As shown in Figure 4, described walking beam assembly 1 includes middle cross beam 11, the left connecting plate 12 being symmetricly set on middle cross beam about 11 two ends and right connecting plate 13 and the left reinforcement angle 14 being separately positioned between the left and right two ends of middle cross beam 11 and left connecting plate 12, right connecting plate 13, right reinforcement angle 15.Several left installation through holes 16 are offered on described left connecting plate 12.Several right installation through holes 17 are offered on described right connecting plate 13.Described left installation through hole, described right installation through hole are arranged with the screw shell one_to_one corresponding on left tail walking beam installation assembly, right tail walking beam installation assembly respectively.
Concrete assembling process of the present utility model is:
First, being connected to left tail longeron assembly and right tail longeron assembly foremost on vehicle frame 6.Then, two ends before and after engine 7 are separately mounted on engine front support assembly 29 and engine rear support assembly 20.Again, screw shell on left installation through hole 16 on left for walking beam assembly 1 connecting plate 12 and left tail walking beam installation assembly 4 is alignd, right installation through hole 17 on right connecting plate 13 and the alignment of the screw shell on right tail walking beam installation assembly 5, use bolt the vertical beam of the left connecting plate 12 of walking beam assembly 1 with left tail walking beam installation assembly 4 to be linked together, use bolt the vertical beam of the right connecting plate 13 of walking beam assembly 1 with right tail walking beam installation assembly 5 to be linked together.
Design principle of the present utility model is:
Described left tail longeron assembly 2 includes the closed loop frame structure that entablature 21, sill the 22, first column 23 and left tail walking beam installation assembly 5 are formed, this closed loop frame structure is overall in pre-large post-small rear receipts type gabarit, i.e. the height of this closed loop frame structure successively decreases the most successively.The utility model has an effect of following several respects by the structure of left tail longeron assembly and right tail longeron assembly is designed as closed loop frame structure: first, this structure is integrally attached on vehicle frame 6 entirely through by the biggest one end, when after the engine front support assembly 29 that engine 7 is assemblied in this structure and engine rear support assembly 20, this closed loop frame structure entirety is by downward power, one end that its junction is namely the biggest in terms of stress distribution law is bigger by stress, therefore, the pre-large post-small design of left tail longeron assembly meets Laws of Mechanics, make more compact structure, take up room less, and consumptive material is beneficial to passenger vehicle lightweight less.Second, in terms of the design principle of passenger vehicle, the body frame structure for automotive of passenger vehicle to meet certain departure angle, and the rear receipts type gabarit of this closed loop frame structure is designed to meet the demand of passenger vehicle departure angle.3rd, diagonal brace 27 is strengthened by the first reinforcement diagonal brace 26 and second in the centre of closed loop frame structure, is reinforced structure, and make structure inner mold groove triangle stablizes little closed loop, and structure is higher, and rigidity is higher.Specifically, first two ends strengthening diagonal brace 26 and the second reinforcement diagonal brace 27 is cuts two sides beveled rectangle beam, the two ends making two reinforcement diagonal braces just can snap at connecting corner, make two reinforcement diagonal braces bigger with the contact surface of closed loop frame structure, this can not only increase structural strength, also the bonding strength at connecting corner is had booster action, and there is four sides upper and lower, forward and backward booster action.4th, engine front support assembly 29 and engine rear support assembly 20 are welded to connect in described closed loop frame structure, and add strong ties by the first column 23, connection column the 28, second column the 24, the 3rd column 25, the most described engine front support assembly 29, engine rear support assembly the 20, first column 23, connection column the 28, second column 24 and the structure of the 3rd column 25, design all in accordance with design feature at residing structure, and connect fully between each structure, meet the connection requirement of engine support, by increasing capacitance it is possible to increase the structural strength of whole tail longitudinal beam structure.
Meanwhile, the utility model also has the functions such as anti-backing and follower's collision prevention concurrently.Tradition passenger vehicle only considered the installation of engine when designing tail longeron, was scraped off the most under steam for guarantee engine sump tank later and usually can increase by two crash-proof brackets, but owing to crash-proof bracket is less, protective capacities is limited.As shown in Figure 5; the feature that the utility model leans forward according to engine; engines tail longitudinal beam structure is designed as pre-large post-small rear receipts type gabarit tail longeron; it not only conforms with mechanics and meets the demand of engine departure angle; can also take into account allows engine entirety lower limb all on tail longitudinal beam structure edge bottom simultaneously, is injured from backing by this design protection engine.Engines tail longitudinal beam structure the most described in the utility model is when passenger vehicle knocks into the back, can quickly transfer force to vehicle frame anterior, making car load participate in stress, resist collision impact, its walking beam assembly 1 is the most horizontal can effectively resist the collision injury to engine at engine 7 rear portion.
Embodiment described above is only to be described preferred embodiment of the present utility model; not scope of the present utility model is defined; on the premise of without departing from the utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that the utility model claims determine.
