Abstract
The present invention relates to an actuator cylinder buffer of electronic automatic transmission control system of mechanical transmission-gear box of automobile. It can smoothly stop the actuator piston moving at high-speed, and is characterized by that the buffer piston and the buffer piston rod are connected into one body by means of nut, and placed in the buffer piston-cylinder formed from buffer piston-cylinder and cylinder cap, and on the top of the buffer piston-cylinder a pressure fuel oil inlet equipped with damping hole and an exhaust outlet are opened, and the pull-rod extended into the actuator piston rod is mounted at the fuel oil hole of left end of the actuator piston, so that the impact force of the actuator piston is transfered to the position of buffer piston via block nut. The adoption of said invented scheme can effectively eliminate the impact shock produced by high-speed movement of the actuator piston so as to ensure the smooth running of car.
Description
The present invention is the actuator hlydro-cylinder buffer of automobile mechanical gear shifting box automatic gear shifting control system.It can guarantee to make the actuator piston of high-speed motion to stop stably.
At present, the used actuator hlydro-cylinder of vehicle automatic transmission system will be because no private buffer will produce impact when work.Especially when the tailpiece of the piston rod operation is arranged, impact obvious especially at large end face by piston.This will reduce the working life of mechanical gear box and the stationarity of automobilism greatly.And the present invention can effectively satisfy the job requirement of automobile mechanical gear shifting box electronic automatic speed control system, makes gear shift steadily satisfy the requirement that car travels.
The present invention is connected as one by nut by damper piston and actuator piston rod.Pack in the damper piston cylinder of forming by damper piston cylinder and cylinder cap.Have pressure entrance and the exhaust port of loading onto damping hole on the damper piston cylinder.Go deep into the pull bar in the actuator hlydro-cylinder piston rod, be installed in the actuator hlydro-cylinder piston, the impact force of actuator piston can be passed to the position of damper piston by stopping nut near the left end oil port.All the other position pull bars do not contact with stopping nut, and damper piston is finished buffer function by damping hole.If actuator need work when moving to left, pressure oil pipe left end filler opening communicates with damper piston cylinder left end filler opening.When the oil-feed of actuator hlydro-cylinder left end, actuator piston and damper piston move right simultaneously, make in the damper piston cylinder to be full of pressure oil, and the right cylinder of damper piston cylinder is by the outlet pipe exhaust.During the right cylinder oil-feed of actuator hlydro-cylinder, when the actuator piston moves quickly near the left end hydraulic fluid port left, through pull bar, stop that nut passes to damper piston bar and damper piston to impact force.Play buffer function by damping hole.Target phase does not play buffer function because pull bar does not contact with stopping nut fast.If actuator need play buffer function when moving to right, only the right cylinder of buffer need be communicated with actuator right-hand member filler opening, the left end filler opening changes outlet pipe into.
Owing to adopt the such scheme can be big, under the little situation of left cylinder piston area, effectively reduce the impact endurance test shock that the actuator piston produces when fast moving stops near the left end hydraulic fluid port left in the right cylinder piston area of actuator.Reach the purpose that actuator piston quick and stable moves, guarantee the smooth running of car.
Description of drawings:
Fig. 1 is a plan view of the present invention.
As shown in Figure 1: the present invention is connected as one by nut (8) by damper piston (10) piston rod (9).Pack in the damper piston cylinder of forming by damper piston cylinder (5) and cylinder cap (7).Have pressure oil left end inlet (1) and exhaust port (2) that damping hole (16) is housed on the damper piston cylinder (5).Go deep into pull bar (13) in the actuator piston rod (14) and be installed near left end hydraulic fluid port (1) and locate, can the impact force of actuator piston (14) be passed to the position of damper piston (10) by stopping nut (12).Finish buffer function by damping hole (16).All the other position pull bars (13) do not contact with stopping nut (12).The buffering if move to left, the left end hydraulic fluid port (1) of pressure oil pipe (4) communicates with damper piston cylinder (5) left end hydraulic fluid port.When actuator hlydro-cylinder (17) left end oil-feed, actuator piston (14) moves right simultaneously with damper piston (10), makes in the left cylinder of damper piston cylinder (5) to be full of pressure oil, and the right cylinder of damper piston cylinder (5) is by outlet pipe (6) exhaust.When the right cylinder of actuator hlydro-cylinder (17) passes through hydraulic fluid port (3) oil-feed, actuator piston (14) is moved to the left fast, near end points hydraulic fluid port (1), the impact force of actuator piston (14) is through stopping nut (12), pull bar (13), damper piston bar (9) and damper piston (10), effectively play buffer function by damping hole (16), whole system is operated steadily.Target phase pull bar (13) does not contact with stopping nut (12) fast, and this has just effectively guaranteed the operation of high regime.
