Abstract
The utility model discloses a mounting bushing of an automobile chassis engine bracket. The mounting bushing comprises a left front mounting bushing, a right front mounting bushing, a left rear mounting bushing and a right rear mounting bushing. An inner hole of the right rear mounting bushing is a primary locating hole, and a fourth mounting bolt penetrates through the primary locating hole to be in location fit with the right rear mounting bushing. An inner hole of the left rear mounting bushing is a secondary locating hole, and a third mounting bolt penetrates through the secondary locating hole to be in location fit with the left rear mounting bushing. An inner hole of the left front mounting bushing and an inner hole of the right front mounting bushing are both assembling via holes, a first bolt penetrates through the inner hole of the left front mounting bushing, and a second bolt penetrates through the inner hole of the right front mounting bushing. According to the mounting bushing of the automobile chassis engine bracket, under the condition that a tray is not used, all-around position precision of a front suspension which is mounted on an entire automobile can be guaranteed, assembling efficiency is improved, and production cost is lowered.
Description
Technical field
The utility model relates to the parts of automobile, relates in particular a kind of mounting bush of car chassis engine holding frame.
Background technology
Four mounting bush that existing car chassis engine holding frame is connected with car body are circular hole, and its aperture is larger, have caused the tolerance clearance of hold-down bolt and mounting bush excessive.Its structure as shown in Figure 2, comprise existing front left mounting bush 11, existing front right mounting bush 12, existing rear left mounting bush 13 and existing rear right mounting bush 14, its structure is identical, the diameter of its endoporus is 18mm, hold-down bolt 2 is all also unified specification, its diameter is 12 mm, due to the only conduct assembling via hole of endoporus of above-mentioned mounting bush, the monolateral tolerance clearance that leaves 3mm of each mounting bush endoporus and hold-down bolt, this gap is larger, while assembling, must use special location tray on manufacturing line, guarantee engine holding frame installation site on car load is accurate.But, location tray cannot be general, once the wearing and tearing of workman's misoperation or location tray locating dowel pin will cause location inaccurate on line, thereby it is partially askew to cause front suspension system to be arranged on car load position generation all around, makes car load occur in the process of moving the phenomenon of sideslip.Therefore, the quality problems that cause in order to stop artificial accidentalia, need be improved the mounting bush structure of existing engine holding frame and car body.
Summary of the invention
The purpose of this utility model is to provide a kind of mounting bush of car chassis engine holding frame, can be in the situation that not using pallet, ensure that front suspension is arranged on car load position all around accurate, and improve efficiency of assembling, reduce production costs.
The mounting bush of car chassis engine holding frame described in the utility model, comprise front left mounting bush, front right mounting bush, rear left mounting bush and rear right mounting bush, described front left mounting bush, front right mounting bush, rear left mounting bush and rear right mounting bush are installed on car chassis engine holding frame, the endoporus of described rear right mounting bush is main knock hole, and the 4th hold-down bolt coordinates with rear right mounting bush location through main knock hole; The endoporus of described rear left mounting bush is secondary knock hole, and the 3rd hold-down bolt coordinates with rear left mounting bush location through secondary knock hole; The endoporus of the endoporus of described front left mounting bush and front right mounting bush is assembling via hole, and the first bolt passes from the endoporus of front left mounting bush, and the second bolt passes from the endoporus of front right mounting bush.
Further, described main knock hole is circular hole, and described secondary knock hole is the bar hole that is lateral arrangement.
Further, described front left mounting bush, front right mounting bush, rear left mounting bush and rear right mounting bush are by metal liner be arranged on rubber coating outside metal liner composition.
When assembling, be first connected with car body through the endoporus of the right back mounting bush as main knock hole with the 4th hold-down bolt, constraint car body is coaxial with the right back mounting bush endoporus of engine holding frame.Now, engine holding frame can only be around the 4th hold-down bolt rotation of right back mounting bush endoporus.Then, pass as time left back mounting bush endoporus of location and be connected with car body with the 3rd hold-down bolt, can only rotate by the 4th hold-down bolt in right back mounting bush endoporus owing to having retrained engine holding frame in the first step, the relative position before and after left back mounting bush endoporus only need retrain can the relative position of stationary engine bracket on car load.Left back mounting bush endoporus is in the monolateral adjusting surplus that leaves 2.5mm of car load left and right directions, convenient for assembly.After the position of engine holding frame is fixed, the endoporus of the endoporus of front left mounting bush and front right mounting bush only, as assembling via hole, does not play the role of positioning.After being finally connected with car body through the endoporus of front left mounting bush and the endoporus of front right mounting bush respectively with the first hold-down bolt and the second hold-down bolt, can be all urgent with instrument.
The mounting bush of car chassis engine holding frame described in the utility model owing to having said structure, can play self-align effect at engine holding frame in fitting process.First, dispense the location tray helping out, reduced productive costs; Secondly, solidify the assembly process of engine holding frame, avoided the randomness of workman's assembling, last, stop because of the assembly error producing that weares and teares of locating dowel pin on pallet, thereby avoided the car load sideslip problem causing because of the installation error of front suspension system on car load.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model coordinates with hold-down bolt;
Fig. 2 is the structural representation that existing car chassis engine holding frame mounting bush coordinates with hold-down bolt.
Detailed description of the invention
In order further to explain the technical solution of the utility model, below by coming by reference to the accompanying drawings, the utility model is elaborated.
Shown in Figure 1, the mounting bush of this car chassis engine holding frame, comprises front left mounting bush 21, front right mounting bush 22, rear left mounting bush 23 and rear right mounting bush 24.Described front left mounting bush 21, front right mounting bush 22, rear left mounting bush 23 and rear right mounting bush 24 are by metal liner and be arranged on the rubber coating composition outside metal liner.Described front left mounting bush 21, front right mounting bush 22, rear left mounting bush 23 and rear right mounting bush 24 are all arranged on car chassis engine holding frame.
