Description
Technical Field
The utility model belongs to the suspension system field of vehicle, concretely relates to suspension system and vehicle behind commercial truck driver's cabin.
Background
The suspension system of the cab of the commercial vehicle is an important system for connecting the cab and the chassis of the truck, and has irreplaceable effects on ensuring driving safety and checking and maintaining vehicles. In the current domestic truck market, a rear suspension system usually adopts a hydraulic lock integration scheme and mainly comprises an elastic element, a guide device and a shock absorber, wherein the shock absorber is used for absorbing the vibration of a truck body and rapidly recovering the truck body to a stable state. In a vehicle suspension system, a hydraulic shock absorber is widely used, a piston rod of the hydraulic shock absorber is connected with a vehicle body, and a cylinder body of the hydraulic shock absorber is connected with a vehicle frame. When the vehicle body and the vehicle frame move relatively, the piston moves up and down in the cylinder body, and oil in the cylinder body repeatedly flows into the other inner cavity from one inner cavity through a plurality of narrow holes. At the moment, the friction between the hole wall and the friction agent liquid molecules of the oil liquid piece forms damping to vibration, and the vibration energy of the vehicle body and the vehicle frame is converted into heat energy to be absorbed by the oil liquid and the cylinder body and finally dissipated to the atmosphere. Such suspension systems are relatively costly and the integration of the coil springs and dampers into a coil spring damper assembly as a key component of the rear suspension system results in further increased costs.
Disclosure of Invention
The utility model aims at providing a suspension system behind commercial truck driver's cabin is on the basis of keeping suspension system damping structure and travelling comfort structure behind, separates into two independent parts with coil spring and shock absorber and separately arranges reduce cost. Meanwhile, a hydraulic lock structure is cancelled, and the functions of limiting and guiding of the hydraulic lock are realized by the tie rod, so that the cost is further reduced.
The purpose of the invention is realized by the following technical scheme:
the utility model provides a suspension system behind commercial truck driver's cabin, includes rear suspension support assembly 1, shock absorber 2, coil spring 3, rubber buffer block 4, upper bracket assembly 5 and drag link 6, rear suspension support assembly 1 and the frame 8 fixed connection of whole car, upper bracket assembly 5 and whole car driver's cabin 7 fixed connection, the both ends of shock absorber 2 respectively with rear suspension support assembly 1 and upper bracket assembly 5 fixed connection, the both ends of coil spring 3 are connected with rear suspension support assembly and 5 upper bracket assemblies respectively, rubber buffer block cloth 4 is arranged in coil spring 3's inside, 6 drag link horizontal arrangement, 6 drag link's one end and upper bracket assembly 5 are articulated, the other end is articulated with rear suspension support assembly 1.
It is a further object of the present invention to provide a vehicle employing the above-described rear suspension system for a commercial truck cab.
The beneficial effects are as follows:
1. the utility model provides a higher problem of suspension system cost behind commercial truck's the driver's cabin, on the basis of keeping rear suspension system damping structure and travelling comfort structure, separate into two independent parts with coil spring and shock absorber and separately arrange, the vibration of decay driver's cabin that not only can be fine makes the driver's cabin homoenergetic when bearing the power of any direction obtain the buffering moreover, improves driver's cabin life, reduce cost.
2. The utility model cancels the hydraulic lock structure, realizes the limit and guide functions of the hydraulic lock by the cross pull rod, further reduces the cost, and simultaneously keeps the damping structure and the comfort structure of the rear suspension system,

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model provides a suspension system behind commercial truck driver's cabin, including back suspension support assembly 1, shock absorber 2, coil spring 3, rubber buffer block 4, upper bracket assembly 5 and drag link 6, back suspension support assembly 1 and the frame 8 fixed connection of whole car, upper bracket assembly 5 and whole car driver's cabin 7 fixed connection, the both ends of shock absorber 2 respectively with back suspension support assembly 1 and upper bracket assembly 5 fixed connection, coil spring 3's both ends respectively with back suspension support assembly and 5 upper bracket assembly be connected, the inside of coil spring 3 is arranged in to rubber buffer block cloth 4, 6 drag link horizontal arrangement, 6 drag link's one end is articulated with upper bracket assembly 5, the other end is articulated with back suspension support assembly 1. The structure is characterized in that the spiral spring and the shock absorber are separated into two independent parts to be separately arranged, a hydraulic lock structure is simultaneously cancelled, the limit and guide functions of the hydraulic lock are realized by the tie rod, the spiral spring 3 and the rubber buffer block 4 are arranged between the rear suspension bracket assembly 1 and the upper bracket assembly 5, the rigidity of the spiral spring 3 plays a role in bearing and providing system rigidity, and a further buffer function is provided through the rubber buffer block 4. The 6 transverse pull rod is horizontally arranged and connected with the 5 upper bracket assembly and the 6 transverse pull rod, and the freedom degree of the 5 upper bracket assembly is limited. Through the structural combination of the 6 transverse pull rod, the 2 shock absorber, the 3 spiral spring and the 4 rubber buffer block, the constraint on the degree of freedom of the 5 upper bracket assembly is realized, the rigidity and the free stroke in the height direction are provided, and the shock absorber provides damping.
In the vehicle driving process of the commercial truck cab rear suspension system, the upper bracket assembly 5 is fixed with the cab and moves along with the cab. The load in the vertical direction is carried by the upper bracket assembly 5 and transmitted to the coil spring 3. Due to the stiffness and elasticity of the coil spring 3, the system can provide a free movement stroke in the vertical direction and improve the comfort. The load in the left and right directions is borne by the upper bracket assembly 5 and is transmitted to the cross-pull rod 6, the cross-pull rod 6 is connected with the rear suspension bracket assembly 1 in a hinged mode and bears the load in the left and right directions, and the function of limiting the left and right swinging of the cab is achieved by limiting the left and right movement of the upper bracket assembly 5.
