Abstract
The utility model is a power takeoff for hydraulic vehicles. Shifting fork is not necessary and control shaft inlaid in splined shaft is adopted. With the coaxial control mode of a pin, a pin hole and a slide groove, the utility model has such advantages as compactness, light weight, higher sensitivity to control and longer working life.
Description
The utility model is a kind of power takeoff that is used on the hydraulic pressure car.
The function of power takeoff is that the engine power of car is taken out, and drives hydraulic oil pump, for hydraulic efficiency pressure system provides power.Present most of power takeoff is to utilize a gear that is enclosed within on the castellated shaft of making output usefulness, with the gear mesh in the change speed gear box, finish this function, gear separates with gearbox gear when not working, during the work of need, stir along castellated shaft by a shift fork and to move to two gears mesh, during separation by the spring pop into position.Owing to use fork controls, shift fork and declutch shift shaft etc. will have a position on shell, enlarged the volume and weight of power takeoff, has increased cost and processing technology program.A kind of no shift fork power takeoff is arranged, and be to finish power taking with a pair of alveolus tooth pawl to incompatible, but its engagement is not steady, and segregation lag is insensitive, and alveolus tooth pawl is easy to wear, the life-span short.
The purpose of this utility model is to provide a kind of no shift fork, little, in light weight, the working process rapid sensitive of volume, the power takeoff that no consumable accessory and life-span are long.
The utility model has been achieved in that a shell, castellated shaft is arranged in the shell, be with driving wheel on the castellated shaft, one section of castellated shaft is tubulose, tubular sections has the chute that connects its diameter vertically, an actuating spindle is arranged in the tubular sections, chute relative position on actuating spindle and the castellated shaft has pin-and-hole, correspondence position with chute and actuating spindle pin-and-hole on the driving wheel also has pin-and-hole, actuating spindle and driving wheel pass the pin-and-hole of chute by separately by pin and are connected, actuating spindle and driving wheel can slide vertically, and actuating spindle is with spring outward, and spring one end withstands on the castellated shaft, one end withstands on the axle cap of actuating spindle, one piston head is arranged on actuating spindle at actuating spindle axle cap end, piston can move vertically, can relatively rotate between piston and the actuating spindle.
There is a recess on actuating spindle axle cap top, and corresponding with it, piston tip has a steel ball.
When needing power taking, piston is subjected to power operated control to promote actuating spindle to move along chute, by pin drive driving wheel move to change speed gear box in gear mesh, the driving wheel rotation also drives the castellated shaft rotation, reaches the power taking purpose.When stopping, external force is removed, and actuating spindle resets under action of the spring, and driving wheel separates with gear in the change speed gear box, finishes power taking work.
Recess is set for actuating spindle and piston and cooresponding steel ball lubricates it each other, reduces friction, rotates more smooth and easy.
Owing to save shift fork, reduced volume weight; Actuating spindle is overlapped in employing in castellated shaft, by the coaxial mode of pin pin-and-hole chute, make control sensitive more, and the life-span is longer.
