Summary of the invention
The invention provides a kind of connecting device for damping spring, solved in the past car chassis and when adjusting height, need change spring, not only load and unload constant, and the high problem of cost.
For solving above-mentioned technical matters, the present invention is by the following technical solutions: the connecting device that is used for damping spring, comprise main body, main body is the rectangle structure of inner hollow, described body interior cavity open end is provided with two parallel plates that are oppositely arranged, parallel plate is provided with mounting hole, described main body is provided with the spring pedestal in internal cavities open end one end upper surface, spring pedestal middle part is provided with fixed leg, described main body is provided with the through hole that runs through main body at spring pedestal and internal cavities open end, also be provided with chute and knock hole on the main body of described spring pedestal place end face, chute and knock hole are positioned at main body away from an end of through hole, described main body also is provided with the lower trailing arm pedestal at arbitrary end face of spring pedestal place end face adjacent both ends face, and lower trailing arm pedestal middle part is provided with joint pin, and tapped bore is established at the joint pin middle part.This programme in use, lower trailing arm pedestal and lower trailing arm are connected, mounting hole cooperates with the joint pin of lower trailing arm, damping spring is directly installed on the spring pedestal, and fixed leg is positioned at the spring inboard, and car chassis is provided with the connecting rod that is connected with main body, connecting rod one end and body cavity coupling also stretch into the body interior cavity, chute is provided with the adjusting lever that is connected with car chassis, and knock hole is provided with fixing screw connecting rod is fixed, and prevents that it from rocking; When adjusting the car chassis height, because the drive of car chassis connecting rod, main body integral body changes with car chassis, when chassis height is adjusted to correct position, main body also changes thereupon, the last levelness of adjusting main body integral body again by adjusting lever is adjusted back adjusting lever locking, and gets final product connecting rod is fixing by knock hole by jam nut; This programme can change with chassis height when adjusting car chassis, the damping spring of Pei Heing also changes thereupon with it, thereby finishes the car chassis Level Change not needing to change under the situation of damping spring, and is not only simple in structure, easy to loading and unloading, and practical, cost is low.
Four fixed orifices have been circularly and evenly distributed on the described spring pedestal.In order to guarantee damping spring stability in use, prevent that it from coming off, so at spring pedestal four fixed orifices that have been circularly and evenly distributed, and two semicircles are set and the pressing plate that is complementary compresses the spring bottom by screw, improve integrally-built safety and stability greatly.
Described main body also is provided with hole clipping at lower trailing arm pedestal place end face.Rock for fear of producing between car chassis connecting rod and the main body, improve the damping property of damping spring, so at the hole clipping place screw is set connecting rod is tightened, thereby improved integrally-built stability.
Described main body adopts the 35CrMo material to make.The 35CrMo alloy structureal steel has very high static strength, dynamic ductility and higher fatigue limit, be make withstand shocks, the common used material of the strength member of bending, top load; Main body adopts 35CrMo not only can prolong the service life of main body, and 35CrMo processing technology maturation, and cost is low.
Compared with prior art, the invention has the beneficial effects as follows: the connecting device of this damping spring of the present invention design, not only simple in structure, cost is low, and is and easy to loading and unloading, can avoid changing damping spring convenient when adjusting car chassis, practical.
