Abstract
The utility model discloses a monolever walking control locking mechanism which comprises a locking handle, a connecting rocker arm and a locking rocker arm, wherein the connecting rocker arm and the locking rocker arm are supported by a fulcrum, the locking handle is fixedly connected with the connecting rocker arm, a connecting rod is connected with the connecting rocker arm and the locking rocker arm through a knuckle bearing, a torsional spring is arranged between an installing pin rod and the locking rocker arm, and two locating pin rods are respectively fixed on two sides of a locking plate of the locking rocker arm. The monolever walking control locking mechanism has a simple structure and good stability, is low in cost, is convenient for maintenance, and can be effectively reduced in labor intensity of drivers, prolonged in service life of a control device and improved in integral safety performance. The monolever walking control locking mechanism can be widely applied to various engineering machinery with a mechanical monolever walking control device.
Description
Technical field
The utility model relates to a kind of monolever walking operated lock mechanism of car, is used for the safe Parking and the starting of vehicle.
Background technology
The lock mechanism of car that the walking of traditional mechanical formula monolever is handled mainly is made up of lock driver handle, moment reforming unit, front and back anti-joyride device and handle registration device; The jam plate elongated slot size of anti-joyride device is generally bigger wherein, with the cumulative limit that guarantees numerous associated mechanisms in the margin of elongated slot.During vehicle parking, the gap of jam plate elongated slot and locating dowel pin can cause handle accurately to fix, and forms potential safety hazard easily; Complicated simultaneously structure is unfavorable for machinery for a long time in the bad working environments operation, also can increase to produce and maintenance cost.
Summary of the invention
The purpose of the utility model provides a kind of monolever walking operated lock mechanism of car; Overcome traditional locks mechanism of car complex forms, the inaccurate defective in location; Realize the accurate location of bar handle; Improve the safety performance of maneuvering system, reduce the production and the maintenance cost of operating control, reduce the strength at repeated alternation of navigating mate.
The purpose of the utility model realizes as follows: this monolever walking operated lock mechanism of car comprises lock driver handle; Other has the connection rocking arm and lock car rocking arm that supports through fulcrum; Lock driver's handle and be connected the rocking arm captive joint; Have connecting rod to pass through oscillating bearing and be connected rocking arm and be connected with lock car rocking arm, torsion spring is installed with locking between the car rocking arm in that pin rod is installed, two positioning pin rods are separately fixed at the jam plate both sides of locking the car rocking arm.Pin rod is installed can make torsion spring close, in the opposite direction to the amount of force of lock car rocking arm with the position of locking the car rocking arm.If lock driver handle is in free position, torsion spring power will make handle fix, and safety switch does not start, and driving engine is with fail to start; When bar handle during in position forward or backward; If be rocked to locked position to lock driver handle this moment; Torsion spring turns over dead center position rear spring power and turns to, and makes handle be fixed on locked position again, and the jam plate circular hole of lock car rocking arm can accurately cooperate with the switching-over locating dowel pin; Bar handle can return Neutral Position accurately automatically, realizes that vehicle safety stops.
The utility model is simple in structure, and is with low cost, and good stability is easy to maintenance, can effectively reduce the strength at repeated alternation of navigating mate, prolongs the service life of operating control, improves the safety performance of complete machine.This mechanism can be widely used in various construction machinery and equipments with mechanical type monolever walking operation apparatus.
Description of drawings
Fig. 1 is the constitution diagram of the utility model lock driver handle when being in free position.
Fig. 2 is the constitution diagram of the utility model lock driver handle when being in locked position.
The specific embodiment
With reference to Fig. 1, Fig. 2; The utility model also has lock driver handle 1; Other has the connection rocking arm 2 and lock car rocking arm 7 that supports through fulcrum, lock driver handle 1 with is connected rocking arm 2 captive joints, have connecting rod 4 to pass through oscillating bearing 3 and be connected rocking arm 2 and lock car rocking arm 7 and be connected; Between installation pin rod and lock car rocking arm 7, the jam plate both sides that 6, two positioning pin rods 5 of torsion spring are separately fixed at lock car rocking arm 7 are installed.
As shown in Figure 1, when lock driver handle 1 is in free position, bar handle can realize forward-reverse, about turn to and action such as speed-change and gearshift; Torsion spring 6 will make lock driver handle 1 fixing; Safety switch is not opened, if vehicle parking, driving engine is with fail to start; This moment, vehicle can emergency, and F illustrates the spring force direction.
As shown in Figure 2, when lock driver handle 1 returned locked position, torsion spring 6 turned over dead center position rear spring power and turns to; F illustrates the spring force direction; Make lock driver handle 1 be fixed on locked position again, and the jam plate circular hole of lock car rocking arm 7 can accurately cooperate with the switching-over locating dowel pin, bar handle can return Neutral Position accurately automatically; Safety switch is unlocked, and this moment, vehicle can safe starting.
