Abstract
The utility model discloses a kind of automobile rear steering joint, including rear trailing arm mounting bracket, prenex pull bar installing hole, lower swing arm installing hole, back prop installing hole, hub pilot hole, brake disc installing hole support, rear transversal control arm installing hole, described rear trailing arm mounting bracket has two, it is separately positioned on the both sides that knuckle is anterior, it is provided with reinforcement flange between rear trailing arm mounting bracket and knuckle front portion, this reinforcement flange and rear trailing arm mounting bracket, anterior and knuckle front end the kink of knuckle connects, both sides and the kink of knuckle front end that knuckle is anterior form a cavity body structure.This utility model after the lifting while slewing journal structure intensity, can reduce the weight of rear steering joint.
Description
Technical field
This utility model relates to the parts of automobile, more specifically to a kind of automobile rear steering joint.
Background technology
Rear steering joint is one of major part on automobile rear suspension system, bears tire, rear trailing arm, back prop, and the shock loading of rear overhang transversal control arm transmission simultaneously.For ensureing trailing wheel accurate positioning in the process of moving, usually require that it has high intensity and size, positional precision.And in order to ensure automobile by ride comfort and economy, it is desirable to lightweight construction.Therefore the structure design of knuckle to consider the stressing conditions of each connection member, on the premise of meeting by force intensity, reduces weight.Conventional slewing journal structure is fairly simple, and under the requirement meeting intensity, weight is bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile rear steering joint, and it after the lifting while slewing journal structure intensity, can reduce the weight of rear steering joint.
Automobile rear steering described in the utility model saves, including rear trailing arm mounting bracket, prenex pull bar installing hole, lower swing arm installing hole, back prop installing hole, hub pilot hole, brake disc installing hole support, rear transversal control arm installing hole, described rear trailing arm mounting bracket has two, it is separately positioned on the both sides that knuckle is anterior, prenex pull bar installing hole is located on the kink of knuckle front end, hub pilot hole is arranged in the middle part of knuckle, it is circumferentially with four wheel hub mounting bolt holes along hub pilot hole on knuckle, brake disc installing hole support is arranged on knuckle top, lower swing arm installing hole and back prop installing hole are located at knuckle bottom.
Further, it is provided with reinforcement flange between rear trailing arm mounting bracket and knuckle front portion, this reinforcement flange is connected with rear trailing arm mounting bracket, anterior and knuckle front end the kink of knuckle, and both sides and the kink of knuckle front end that knuckle is anterior form a cavity body structure.
Further, the thickness a of the connecting portion between lower swing arm installing hole and back prop installing hole is 4-5cm, and its width b is 2-2.5cm.
Automobile rear steering described in the utility model saves, loading characteristic according to rear steering joint, reasonably arrangement form, the region big to stress, carrying out structural strengthening, this cavity body structure is bearing capacity and stability under equivalent weight, the stent-like structure conventional higher than conventional steering joint, so cavity wall thickness is smaller than conventional steering joint thickness, reduce construction weight.While this utility model slewing journal structure intensity after the lifting, reduce the weight of rear steering joint.

Detailed description of the invention
In order to the technical solution of the utility model is explained further, come that the utility model is elaborated below in conjunction with the accompanying drawings.
See shown in Fig. 1 and Fig. 2, this automobile rear steering saves, including rear trailing arm mounting bracket 1, prenex pull bar installing hole 2, lower swing arm installing hole 3, back prop installing hole 4, hub pilot hole 5, brake disc installing hole support 6, rear transversal control arm installing hole 7, described rear trailing arm mounting bracket 1 has two, it is separately positioned on the both sides that knuckle is anterior, prenex pull bar installing hole 2 is located on the kink of knuckle front end, hub pilot hole 5 is arranged in the middle part of knuckle, it is circumferentially with four wheel hub mounting bolt holes 8 along hub pilot hole 5 on knuckle, brake disc installing hole support 6 is arranged on knuckle top, lower swing arm installing hole 3 and back prop installing hole 4 are located at knuckle bottom.Reinforcement flange 9 it is provided with between rear trailing arm mounting bracket and knuckle front portion, this reinforcement flange 9 is connected with rear trailing arm mounting bracket, anterior and knuckle front end the kink of knuckle, forms a cavity body structure between both sides and the kink of knuckle front end and reinforcement flange 9 that knuckle is anterior.Knuckle is when carrying longitudinal loading, and the region of stress maximum occurs in rear trailing arm near support region, and this cavity body structure strengthens strength and stability.
See shown in Fig. 3 and Fig. 4, connecting portion region between lower swing arm installing hole 3 and back prop installing hole 4 is the knuckle region that stress is maximum when carrying transverse load, in order to make full use of the ability of material opposing transverse load, reduce the longitudinal size a of this connecting portion be 4cm(also can be 5cm), increase the lateral dimension b of this connecting portion be 2cm(also can be 2.5cm), to increase the bending resistance the moment of inertia of opposing transverse load.
