The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein includes
Any and all combinations of one or more related listed items.
The rear longitudinal push rod bushing 10 provided referring to FIG. 1 to FIG. 4, for the utility model first embodiment, for it is rear
Longitudinal push rod matching uses.As shown in Figures 1 to 4, which includes one and outer skeleton 11,12 and of inner frame
Rubber sleeve 13.In a ring, rubber sleeve 13 is embedded in outer skeleton 11 outer skeleton 11, and the middle part of inner frame 12 is sheathed in rubber sleeve
In 13, inner frame 12 includes the assembling assembly 121 being embedded in rubber sleeve 13 and the first support set on 121 both ends of assembling assembly
Component 122 and the second support component 123.First support component 122 and the second support component 123 are symmetrical about assembling assembly 121
It is arranged and extends rubber sleeve 13, the both ends of the first support component 122 and the second support component 123 offer the first dress respectively
Distribution 1221 and the second pilot hole 1231, are fixed for wearing bolt with automobile assembling.
Longitudinal push rod bushing 10 after provided by the utility model realizes the rigidity of bushing by inner frame 12 and outer skeleton 11
It is required that the first support component 122 and the second support component 123 that the both ends of inner frame are extended make inner frame without wearing spiral shell
Bolt and rear longitudinal push rod bracket assemble, first opened up respectively in the end of the first support component 122 and the second support component 123
Pilot hole 1221 and the second pilot hole 1231 are assembled with automobile by bolt, the process that longitudinal push rod bracket after assembly is omitted,
The tolerance stack for reducing intermediate sizes is conducive to preferably control dimensional tolerance, reduces the assembly of rear longitudinal push rod bushing
Difficulty.
As shown in Fig. 2, the outer wall 131 of rubber sleeve 13 is arc-shaped, chimeric on the inside of outer skeleton 11, assembling assembly 13 is in ring
Shape boss-shaped is embedded in the inner wall 132 of rubber sleeve 13, is set between the inner and outer wall of rubber sleeve 13 there are four cavity 133.It is empty
The setting of chamber 133 increases the elastic potential energy of rubber sleeve 13.And then reinforce the resiliency that jolts of the rear longitudinal push rod bushing 10
Energy.
Further, the first support component 122 and the second support component 123 are set as slab.Slab be arranged so that
The thickness of first support component 122 and the second support component 123 is smaller, in order to be set to the first support component 122 and second
The first pilot hole 1221 and the second pilot hole 1231 on support component 123 wear bolt.It reduces and wears bolt in assembling process
Difficulty.
Specifically, in order to make rear 10 uniform force of longitudinal push rod bushing, the first pilot hole 1221 and the second pilot hole 1231
The hole heart it is symmetrical about assembling assembly 121.So that longitudinal push rod bushing 10 is by the power of body of a motor car by first after after mounting
Support component 122 and the second support component 123 are uniformly transferred to rubber sleeve 13.
It should be understood that for the integral firmness of inner frame 12, in the first support component 121, the second support component 123
It is equipped with reinforcing rib 124 with 121 junction of assembling assembly, which promotes the connection of junction around the periphery of junction
Intensity and fastness.
Further, in order to adapt to the error amount in technique production, the second pilot hole 1231 is set as waist-shaped hole, to meet
Normal assembly in certain deviation range.
Referring to Fig. 5, for the rear longitudinal push rod bushing 10a that provides of two embodiments of the utility model, feature is real with one
It is essentially identical to apply example, difference place is, the side edge of the first support component 122 and the second support component 123 is equipped with flange
125, to reinforce the bending resistance of the first support component 122 and the second support component 123.
The rear longitudinal push rod bushing 10a of this practical offer realizes that the rigidity of bushing is wanted by inner frame 12 and outer skeleton 11
It asks, the rubber sleeve 13 between inner frame 12 and outer skeleton 11 plays damping and cushion effect, and the both ends of inner frame extend
The first support component 122 and the second support component 123 out makes inner frame rack-mounted without wearing bolt and rear longitudinal push rod branch
Match, is assembled respectively in the first pilot hole 1221 and second that the end of the first support component 122 and the second support component 123 opens up
Hole 1231 and automobile are assembled by bolt, and the process that longitudinal push rod bracket after assembly is omitted reduces the tolerance of intermediate sizes
Superposition is conducive to preferably control dimensional tolerance, reduces the assembly difficulty of rear longitudinal push rod bushing.
In addition, the embodiments of the present invention additionally provide a kind of rear longitudinal push rod assembly, referring to Fig. 6, vertical after described
It include push rod 20 and rear longitudinal push rod bushing to push rod assembly, which can be using above-mentioned first embodiment
Longitudinal push rod bushing 10 or the rear longitudinal push rod bushing 10a of second embodiment afterwards, push rod 20 include a body of rod 21 and are set to
The outer skeleton 11 of the outer tube 22 of rod end, outer tube 22 and rear longitudinal push rod bushing 10 is interference fitted, and bears to turn to meet
The condition of square.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
