Abstract
The invention discloses a vibration damping support device at the rear of an automotive cab, which is characterized in that: the rear of the automotive cab is connected with an upper beam of the vibration damping support device which is formed by integral stamping of a steel plate; a door-shaped lower support of the vibration damping support device which is formed by integral stamping of the steel plate and a lower bracket of a vibrator which is formed by integral stamping of the same steel plate are welded into a door-shaped lower support assembly of the vibration damping support device; and the door-shaped lower support assembly of the vibration damping support device is connected with a frame. Two spiral springs and bidirectional application cylinder type vibrators are arranged between two ends of the upper beam of the vibration damping support device and the door-shaped lower support assembly of the vibration damping support device. When the cab is close to the frame, namely when a vibration damping connecting device compresses the stroke, the damping force of the vibrator is small, so that the elasticity of the spiral springs is fully utilized to buffer the impact; and when the cab is away from the frame, namely when the vibration damping connecting device extends the stroke, the damping force of the vibrator is large to quickly damp the vibration. Due to the arrangement of the vibration damping support device, the ride in the automotive cab is very comfortable.
Description
Technical field
The present invention relates to a kind of shock attenuation unit, particularly a kind of vibration damping support device at rear of automotive cab.
Background technology
Operator's compartment is the place of goods carrying vehicle occupant work, and particularly in long-distance transport, operator's compartment still is occupant's recreating facility, and the traveling comfort of operator's compartment produces great influence to occupant's work and life.Present automobile cab is connected with the chassis, be actually and the connection mode of vehicle frame is: adopting bolted connection again behind the rubber pad on the pad between operator's compartment and vehicle frame, the purpose of doing like this is to eliminate installation difficulty and the discontinuity that operator's compartment causes with the relative manufacturing errors of vehicle frame, and can partly reduce vibration, but effectiveness in vibration suppression is relatively poor, and rubber pad is aging easily, damage, and service life is shorter.
Summary of the invention
The present invention proposes a kind of vibration damping support device at rear of automotive cab, and it can overcome the problems referred to above.
This vibration damping support device at rear of automotive cab provided by the invention, operator's compartment is anterior with to be installed on frame lug hinged by bearing pin, it is characterized in that: rear cabin links to each other with the vibration damping support device entablatrance of the whole drawing of steel plate, the vibration damping support device door shape undersetting of the whole drawing of steel plate becomes vibration damping support device door shape undersetting assembly with the shock absorber lower bracket assembly welding of the whole drawing of same steel plate, and vibration damping support device door shape undersetting assembly links to each other with vehicle frame; Between the two ends of vibration damping support device entablatrance and vibration damping support device door shape undersetting assembly, two coil springs and double adjustable shock absorber are housed.
Between the two ends of vibration damping support device entablatrance and vibration damping support device door shape undersetting assembly, two coil springs and double adjustable shock absorber are housed, similar automotive suspension.Close at operator's compartment and vehicle frame, promptly during the vibration damping support device compression stroke, absorber damping force is less, so that make full use of helical spring elasticity, with shock absorbing; Operator's compartment and vehicle frame away from, promptly during the vibration damping support device extension stroke, absorber damping force is bigger, in the hope of rapid vibration damping.And the system of assurance frequency of natural vibration is in vertical shake frequency 1～1.6Hz scope that human body is accustomed to.The frequency of natural vibration n of system calculates with following formula:
K＝Mg/f
In the formula: the K-suspension rate, refer to the unit distance that vibration damping support device moves down under the effect of power vertically downward, even the unit vertical compression distortion that vibration damping support device produces, the required vertical load that is added on the vibration damping support device;
M-vibration damping support device spring carried mass;
The g-acceleration due to gravity;
The vertical deformation of f-vibration damping support device also claims amount of deflection.
When the vibration damping support device parameter designing is calculated, can be according to the size of operator's compartment, i.e. the size of M-vibration damping support device spring carried mass is selected the spring of respective springs stiffness K, guarantees that system's frequency of natural vibration is in the scope of 1～1.6Hz.
Between vibration damping support device entablatrance and vibration damping support device door shape undersetting assembly, a lateral rod is housed, lateral rod two ends head is porose, rubber bush is housed in the hole, two bearing pins pass rubber bush respectively be installed in the vibration damping support device entablatrance and link to each other with the lateral rod undersetting with lateral rod upper bracket on the vibration damping support device door shape undersetting assembly, and formation rubber hinge, transmit transverse force, the side travel amount of restriction entablatrance and operator's compartment.
Between vibration damping support device entablatrance and vibration damping support device door shape undersetting assembly, two longitudinal spacing devices are housed, the amount of movement that restriction vibration damping support device entablatrance makes progress prevents that vibration damping support device entablatrance and operator's compartment are away from vibration damping support device door shape undersetting assembly.
After said apparatus is installed, take as snug as a bug in a rug in that vehicle drive is indoor, for the goods carrying vehicle occupant provides a good operation and living environment.
