Description
Technical field
The utility model relates to a kind of environmental sanitation vehicles torque arm oil cylinder.
Background technique
The mounting-and-dismounting device generally adopted in the cargo handling process in current engineering truck compartment establishes a hook at torque arm top, for hooking handle before compartment to control compartment during work, torque arm is also provided with for the hinge hinged with oil hydraulic cylinder, torque arm oil cylinder is fixed on underframe, oil cylinder piston top and torque arm hinged, when compartment dumps, the coupling shaft being arranged on underframe afterbody with pay a frame and be connected, to have been stretched dumping of compartment by torque arm oil cylinder; When getting on or off the bus in compartment, the articulated mounting be arranged in the middle part of underframe is connected with torque arm, and torque arm oil cylinder has stretched getting on or off the bus of compartment.Due to the bulky Heavy Weight of articulated mounting, the volume in compartment is diminished greatly, also reduces fuel economy simultaneously, had a strong impact on the competitiveness of product in market, greatly reduce the benefit of enterprise.
Simultaneously existing in operation process, also discharge large quantity of exhaust gas, increase the weight of the atmospheric pollution in city, and mobility and sealability poor, working efficiency is lower, needs often maintenance and changes, increasing cost, reducing the utilization ratio of vehicle.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provides one to have good mobility and sealability, need not often keep in repair and change, the environmental sanitation vehicles torque arm oil cylinder of increasing work efficiency.
The utility model solves the technological scheme that its technical problem adopts: a kind of environmental sanitation vehicles torque arm oil cylinder, there is cylinder body, piston rod is provided with in described inner chamber of cylinder block, one end of piston rod is provided with piston, its the other end is provided with axis hole, the opening of cylinder body is provided with gland, the inwall of piston and cylinder body is slidably connected, cylinder body is divided into rod chamber and rodless cavity by piston, the outer surface of piston is provided with piston packing ring, piston and joint, piston rod top are provided with Cock screw, and gland and piston rod joint are provided with junket ring.
Further, one end of described cylinder body is provided with axis hole, is provided with bearing sleeve in axis hole.
Further, bolt is provided with between the top of described cylinder body and gland.
Further, described piston rod is provided with oil guiding hole.
Further, described piston rod adopts 45 Steel materials to make, and surface hardness is HB=230-250, and the surface spraying of piston rod has hard chromium layers.
The beneficial effects of the utility model are: the utility model structure is simple, use and simple to operation, and volume is little, has good mobility and sealability; need not often keep in repair and change, increase work efficiency, reduce costs; improve the utilization ratio of vehicle, safe and reliable, protection of the environment.
