Abstract

The invention belongs to an engineering machinery control technology and mainly relates to a left-right-hand throttle linkage assignment controller of a road roller. The assignment controller mainly comprises a left-right-hand throttle controller, a power takeoff rocker arm (5), an extension return spring (14) and a support (13), wherein the control crank of the left-right-hand throttle controller is connected with a rocker arm (6) via a handle throttle wire; the power takeoff rocker arm (5) is hinged on the connection shaft (8) of the support (13), one end of the power takeoff rocker arm (5) is in a rod-shaped structure and the other end thereof is connected with an engine throttle via an engine throttle wire (4); one end of each two rocker arm (6) leans against one end of the power takeoff rocker arm and is connected with the hand throttle wire of a hand throttle controller and the other end thereof is hinged on the connection shaft (8) of the support; and the two rocker arms (6) connected on the connection shaft are arranged at the two sides of the power takeoff rocker arm in a symmetrical manner. In the invention, the hand throttle controllers at the left and right sides of an operation floor can be controlled, thus realizing control of an engine.

Description

Left-right-hand throttle linkage assignment controller of road roller

Technical field

The invention belongs to engineering machinery control technology, relate generally to a kind of left-right-hand throttle linkage assignment controller of road roller.

Background technique

Development along with domestic engineering machinery, constantly there is new type to release in the road roller field, the continuous injection of high and new technology, make the user require also to improve to the handling of complete machine thereupon. along with the appearance of full racing slick road roller, its unique dual operation platform design, make traditional manual accelerator control control seem comparatively backward. traditional road roller manual accelerator control is handled and is adopted lever principle, owing to need left and right sides driving operation, the left-right-hand throttle operating handle need be connected in parallel by intermediate conversion mechanism, connect diesel engine by connecting rod again. because the diesel engine limited location, make very difficulty of a whole set of manual accelerator control controller mechanism mounting arrangement. in order to dodge sebific duct and other component in the vehicle, rod hinge connection mechanism is very many, cause whole manoeuvring performance inefficiency, handle heavy.

Summary of the invention

For solving the problems of the technologies described above, the present invention seeks to propose a kind of left-right-hand throttle linkage assignment controller of road roller, about being possessed, it drives manual accelerator control to handle mutual noninterference, and it is convenient to install, and handles comfortable characteristics such as non-maintaining.

The present invention takes following technological scheme:

A kind of left-right-hand throttle linkage assignment controller of road roller mainly comprises left hand and right hand throttle control, power taking rocking arm, stretching Returnning spring and support; Described manual accelerator control controller is made of Joystick and rocking arm, and described Joystick is connected by hand throttle wire with rocking arm; Described manual accelerator control controller is used for making hand throttle wire drive the rocking arm action by Joystick, and described left hand and right hand throttle control is separately positioned on two positions of operating table; Described power taking rocking arm is hinged by the coupling shaft of its middle part hinging hole and support, and an end of power taking rocking arm is connected with engine throttle by acceleration cable, and the other end of power taking rocking arm is a rod shaped structure; The end that described two rocking arms are connected with hand throttle wire rides against on the bar of power taking rocking arm one end, the other end of described two rocking arms is connected on the coupling shaft of support and can rotates relative to coupling shaft, constitute arbitrary rocking arm under Joystick, hand throttle wire effect, all can drive the structure of power taking rocking arm, acceleration cable action; Described two rocking arms that are connected on the coupling shaft are positioned at the both sides of power taking rocking arm and are symmetrical arranged; The end that described power taking rocking arm is connected with acceleration cable connects the stretching Returnning spring, and the other end of described stretching Returnning spring is connected with support.

The left-right-hand throttle linkage assignment controller of road roller that the present invention proposes, operation left hand and right hand throttle control seesaws, and all can drive the action of power taking rocking arm, is driven the engine throttle backguy of below by the power taking rocking arm; All can handle the manual accelerator control controller of this position in the position, the left and right sides of operating table, realize control motor.
