Description
Technical field
The utility model relates to automotive fields, and in particular to a kind of heavy-duty car front suspension locking device.
Background technique
Automotive suspension is the device of connecting vehicle frame and axle elastic in automobile.Main task is to mitigate to be passed by uneven road surface
To the impact of vehicle frame, to improve comfort by bus.China's heavy type sweeps road special-purpose vehicle and mostly uses Leaf Spring Suspension greatly at present.It sweeps
Road car is divided into working condition and transition state by operating status, and speed is slow under working condition, to the operation is stable of road sweeping device
Property has higher requirements；Normal vehicle operation under transition state, it is more demanding to ride comfort.
But special-purpose vehicle, in working condition, speed is lower, road conditions are more smooth, and this vibration-damping function use of suspension is not
Greatly, instead because the sensitivity of sensor is higher, slight vibration can be also collected, and if road sweeper is in working condition, be advanced
In the process since the damping effect of vehicle front suspension device, leaf spring can vibrate up and down therewith, sensor herein is placed in height
Degree is very sensitive, can be floated up and down therewith by the road sweeping device that sensor controls height, to cause clearing apparatus workability
It can be unstable.
Summary of the invention
The purpose of this utility model is that solve the above-mentioned problems and provides a kind of heavy-duty car front suspension locking dress
It sets, makes vehicle front suspension locking in working condition, avoid road sweeping device caused by vibrating from cleaning unstable；When the normal row of vehicle
When sailing, then restore the damping property of front suspension device.
The utility model achieves the above object through the following technical schemes:
A kind of heavy-duty car front suspension locking device, including hydraulic cylinder, the upper end of the hydraulic cylinder by upper bracket with
The connection of chassis central sill, the lower end of the hydraulic cylinder is connect by lower bracket and preceding bridging；Between upper and lower two hydraulic fluid port of the hydraulic cylinder
It is connected by the first hydraulic path, and the first hydraulic path is connect by the second hydraulic path with accumulator, and first is hydraulic logical
The connection of road and the second hydraulic path crosses position equipped with lockup switch.
Using above technical scheme, wherein hydraulic cylinder upper end is connect by upper bracket with chassis central sill, under lower end passes through
Bracket connects with preceding bridging, and when lockup switch is closed, access is cut off, and hydraulic cylinder locking limits the vibration of front suspension, locking
Device works；When lockup switch is opened, pathway patency, locking device does not work, and front suspension can restore vibration-damping function；It is described
Accumulator is connect by the second hydraulic path with hydraulic cylinder, is used in hydraulic cylinder accumulation of energy.
Preferably, the upper bracket includes fixed plate and connecting plate, the fixed plate is solid by bolt and chassis central sill
Fixed connection；The connecting plate is two fonts, and the telescopic rod of hydraulic cylinder reaches between the connecting plate of two font, and uses locking screw
It tethers and connects.
Preferably, the lower bracket is connect by bolt and preceding bridging, and connected by the lower end of clamping screw hydraulic cylinder
It connects.
To sum up, it the utility model has the beneficial effects that: structure is simple, reliability is relatively strong high, is mounted on and sweeps road special-purpose vehicle
Preceding bridge overcomes floating problem when working condition, while also retaining the vibration-damping function of itself.
