Abstract

The utility model relates to a neutral-gear engaging device of a three-wheeled vehicle united rear axle, in particular to a novel disconnected neutral-gear engaging device. When a driver wants to leave the driving position transitorily and presses on a clutch pedal arm, and lateral force can be exerted to a direction of a locking shaft after the clutch pedal arm is pressed down. The clutch pedal arm is deviated to the lower side of the locking shaft under action of the lateral force because a certain clearance is formed between a kinematic pair of the clutch pedal arm. After force of the clutch pedal force is removed, upwards bounce action of the clutch pedal arm can be blocked by the locking shaft under action of return force, and then the clutch pedal arm is locked at a clutch position. The novel disconnected neutral-gear engaging device has the advantages of simple structure, convenient operation and reliable performance.

Description

A kind of novel breakaway-element is plucked blocking means

Technical field:

The utility model relates to the retaining device of plucking of the conjuncted back axle of a kind of three wheeled motor vehicle, relates in particular to a kind of novel breakaway-element and plucks blocking means.

Background technology:

The conjuncted back axle of agricultural three wheeled motor vehicle is owing to influenced by manufacturing cost etc., the part accuracy of manufacture is not high, put neutral gear position when often causing the driver to want to stop difficulty takes place, the general employing of driver's this moment method that diesel engine is flame-out, but this method only thinks that to the driver of short duration parking is uneconomic; In addition because the vibration of single cylinder three wheeled motor vehicle is bigger, in the get off effect of accidentalia such as being vibrated easily when handling affairs of the of short duration parking of driver, cause unexpected engage a gear, thereby cause the accident, traditional way is a pull-up parking brake when stopping, but like this when meeting accident engage a gear owing to do not disconnect propulsion source, will cause the impact of transmission device to destroy to such an extent as to the braking force that armrest is stopped is flame-out by force, the parking brake braking force deficiency that many agricultural tricycles are arranged still more can't realize allowing diesel engine stop the effect of putting out by force.

Summary of the invention:

The purpose of this utility model provides a kind of simple in structure, easy to operate, the auxiliary retaining device of plucking of the conjuncted back axle of dependable performance for overcoming the deficiencies in the prior art.

The technical solution of the utility model is achieved in that and adds a lockable mechanism in the clutch circuit of agricultural three wheeled motor vehicle, this mechanism is that a kind of breakaway-element is plucked retaining device, stepping on arm by locking shaft and clutch forms, locking shaft is a L type round steel, the one end is welded on the vehicle frame, and the vertical weak point of the other end is curved can to prevent that clutch from stepping on arm in the lock position slippage.When clutch is stepped on arm and is depressed, the of short duration steering position that leaves of driver's desire, can be after depressing clutch and stepping on arm, direction to locking shaft applies side force, step on because of clutch between the kinematic pair of arm and have certain clearance, so clutch is stepped on arm being biased under the effect of side force below the locking shaft, after clutch pedal power is removed, clutch is stepped on the pop up motion of arm under the effect of restoring force and is stopped by locking shaft, thereby realizes that clutch steps on arm and be locked at clutch position.

The utlity model has simple in structurely, easy to operate, the advantage of dependable performance can realize separating of transmission device and propulsion source fast, is used with parking brake to make vehicle realize safer Parking.

Description of drawings:

On behalf of clutch, the utility model structural front view among Fig. 1, dotted line step on the state that arm depresses.

Fig. 2 is the A-A section-drawing of Fig. 1.

1. locking shaft among the figure, 2. arm is stepped in clutch.

The specific embodiment:

As shown in Figure 1 and Figure 2, a kind of novel breakaway-element is plucked blocking means, steps on arm 2 by locking shaft 1, clutch and forms, and it is characterized in that:

When clutch is stepped on arm 2 and is depressed, the of short duration steering position that leaves of driver's desire, can be after depressing clutch and stepping on arm 2, direction to locking shaft 1 applies side force, step on because of clutch between the kinematic pair of arm 2 and have certain clearance, so clutch is stepped on arm 2 and is being biased under the effect of side force below the locking shaft 1, after clutch pedal power is removed, clutch is stepped on the pop up motion of arm 2 under the effect of restoring force and is stopped by locking shaft 1, thereby the realization clutch is stepped on arm 2 and is locked at clutch position, locking shaft 1 is a L type round steel, and the one end is welded on the vehicle frame usually, and L shaped weak point is curved can to prevent that clutch from stepping on arm 2 in the lock position slippage; When needs unlock state, only need firmly clutch is stepped on once more arm and step on 2 times and apply side force to locking shaft 1 opposite sense, when clutch step on arm 2 move apart locking shaft 1 under the time, unclamp clutch and step on the joint once more that arm 2 can be realized power-transfer clutch; When normal vehicle operation need depress clutch and steps on arm 2, as not applying comparatively significantly to the side force of locking direction, then the locking phenomenon can not take place, thereby guarantee the normal operation of vehicle.

Claims

1. a novel breakaway-element is plucked blocking means, comprise: arm (2) is stepped in locking shaft (1), clutch, it is characterized in that: locking shaft (1) is a L type round steel, and the one end is welded on the vehicle frame, and the vertical weak point of the other end is curved can to prevent that clutch from stepping on arm (2) in the lock position slippage.
