Description
Technical field
The utility model relates to electrification contact network comprehensive maintenance garage and walks the hydraulic closed driving system.
Background technology
It is one of actuating unit of wanting of electrification contact network comprehensive maintenance car weight that the hydraulic closed driving system is walked by electrification contact network comprehensive maintenance garage, the running gear of traditional electrification contact network comprehensive maintenance car adopts two cover systems usually, and a cover hydraulic mechanical transmission system is used for walking at a high speed; Another set of hydraulic efficiency pressure system is used for the low speed walking; At a high speed, the low speed walking must be switched total system complex operation, configuration complexity manually.Formations such as closed type hydraulic pump, brake activation valve group, Closed Hydraulic motor and electric control handle that the hydraulic closed transmission adopted has been walked by present electrification contact network comprehensive maintenance garage, when work, by moving forward and backward of electric control handle operation vehicle, and can realize the stepless control of the speed of travel.
In actual use, because the job requirements of electrification contact network comprehensive maintenance car is relatively harsher, walking to the railway maintenance car has proposed requirements at the higher level, adopt walking hydraulic closed driving system, can realize the matched well of walking at a high speed and the walking of the low speed when job execution, it is simpler and more direct, compact that driving system is walked by the contact system comprehensive maintenance garage that electrifies railways.
Summary of the invention
Walk the present situation of hydraulic closed driving system at having electrification contact network comprehensive maintenance garage now, the electrification contact network comprehensive maintenance garage that the utility model provides walks the hydraulic closed driving system and develops for solving this difficult problem.This system can realize the matched well of walking at a high speed and the walking of the low speed when job execution.
The purpose of this utility model is achieved in that
A kind of electrification contact network comprehensive maintenance garage walks the hydraulic closed driving system and mainly is made up of Hydraulic Pump, HM Hydraulic Motor, electric control handle, hydraulic oil cooler, the meticulous oil filter of slippage pump, braking electromagnetic valve group in current and high-pressure ball valve, connecting line.HM Hydraulic Motor is installed concentratedly on HM Hydraulic Motor is made a concerted effort case, and electric control handle is installed on the interior driver control plate of maintenance car, and is connected with Hydraulic Pump by cable; Hydraulic oil cooler is connected with the system hydraulic reservoir by pipeline; Two high-pressure ball valves are installed between motor operations hydraulic fluid port and the braking electromagnetic valve group in current, and the thin oil filter of repairing pump pressure olein is plugged on the Hydraulic Pump, and the braking electromagnetic valve group in current is connected in parallel by pipeline and HM Hydraulic Motor actuator port.
The beneficial effect of advantage of the present utility model and generation is:
Advantages such as the maintenance car running part of relying on oneself adopts the Closed Hydraulic drive technology, and the Closed Hydraulic transmission has simple in structure, makes, installation, maintenance is convenient, and driving efficiency height, flexible operation, fault rate are low, speed-regulating range width, accelerating performance are good.Main hydraulic such as HM Hydraulic Motor, Hydraulic Pump and bar handle are all selected for use and are in the U.S. Sa Ao company product of most advanced level in the world in Closed Hydraulic drive technology field.Rail vehicle enclosed transmission adopted divariant system, promptly controllable capacity pump-variable-dis-placement motor system can obtain bigger speed range.
Description of drawings
Fig. 1 is that hydraulic closed driving system schematic diagram is walked by electrification contact network comprehensive maintenance garage.
The specific embodiment
Below, in conjunction with the accompanying drawings, the utility model is further described again:
As shown in Figure 1, the moment of torsion that machine driven system that the hydraulic closed driving system partly is made up of diesel engine propulsion box, make a concerted effort case and lubricating system thereof, pneumatic clutch, universal coupling, axle gear box etc. is walked by a kind of electrification contact network comprehensive maintenance garage provides closed fhdraulic system is delivered to wheel, the driving maintenance car.Electrification contact network comprehensive maintenance garage walks the hydraulic closed driving system and is made up of Hydraulic Pump 3, HM Hydraulic Motor 7, electric control handle 1, hydraulic oil cooler 2, the meticulous oil filter 4 of slippage pump, braking electromagnetic valve group in current 5 and high-pressure ball valve 6, connecting line etc., closed system adopts a bidirectional variable axial plunger pump, change direction and the flow that Hydraulic Pump is discharged hydraulic oil by handling electric handle, realize the speed change and the commutation of actuating unit; System adopts four HM Hydraulic Motor 7 to install concentratedly on HM Hydraulic Motor is made a concerted effort case, and the propulsive effort that HM Hydraulic Motor 7 produces is delivered to wheel by the output shaft and the travelled by vehicle retarder of the case of making a concerted effort with propulsive effort, thereby realizes vehicle to run; Two electric control handles 1 are installed on respectively on two interior driver control plates of maintenance car, handle the step-less adjustment of advancing, retreating and realize vehicle to run speed that electric control handle 1 can be realized vehicle; Two electric control handles 1 are connected with Hydraulic Pump 3 by cable; Hydraulic oil cooler 2 is connected with hydraulic reservoir with system by pipeline; Effect is that the leakage hydraulic oil of heat that Hydraulic Pump in the system 3, HM Hydraulic Motor 7, high-pressure ball valve 6 produce is returned hydraulic reservoir through over cooling, and the control system temperature rise guarantees system's normal operation; The fan of cooling vessel is by its fluid motor-driven that carries, and the pressure oil of HM Hydraulic Motor 7 comes from vehicle hydraulic system on the vehicle; The thin oil filter 4 of repairing pump pressure olein is plugged on the Hydraulic Pump 3, the hydraulic oil that enters closed fhdraulic system is filtered, to guarantee the cleaning of closed fhdraulic system hydraulic oil, filtering accuracy 20 μ m; Braking electromagnetic valve group in current 5 is connected in parallel by pipeline and HM Hydraulic Motor actuator port, and effect is in order to prevent that HM Hydraulic Motor 7 from producing the pump operating mode because of hypervelocity, the infringement motor.The electromagnet of electro hydraulic valve gets system's normal operation when electric, and the electromagnet of electro hydraulic valve gets the electric electric control handle 1 that comes from synchronously.System is provided with two high-pressure ball valves 6, and they are installed between motor operations hydraulic fluid port and the braking electromagnetic valve group in current 5, and high-pressure ball valve 6 must be in the complete opening state during system normal operation; Have only the system of working as automatically controlled malfunctioning unusual condition to occur, when having adopted emergency hand control, handle, must close two high-pressure ball valves,, guarantee system's normal operation so that braking electromagnetic valve group in current 5 is inoperative in order to enable manual-operated emergent.This moment is because braking electromagnetic valve group in current 5 is inoperative, and is therefore also corresponding inoperative to the protection of motor hypervelocity, so chaufeur should rationally be controlled engine speed and running velocity when manual-operated emergent is handled.
