CN202863147U - Connection device for automobile clutch master cylinder and pedal - Google Patents

Abstract

The utility model discloses a connection device for an automobile clutch master cylinder and a pedal consisting of a clutch master cylinder, a pushing rod and a pedal, wherein the pushing rod matches with the clutch master cylinder, the pedal is ball and a ball socket matching with the pushing rod. Preferably, the coordination between the pedal and the pushing rod is realized by a structure which is a connection head arranged between the pedal and the pushing rod, the pedal matches with one end of the connection head in a fast plug-in mode, the other end of the connection head is a structure in the shape of a ball socket which is ball and a ball socket matching with the pushing rod. According to the connection device for an automobile clutch master cylinder and a pedal, when a driver steps the clutch pedal, the coordination place of the pedal and the clutch master cylinder is the mutual friction area of metal pins on the pedal wall and connection heads in the clutch master cylinder, the ball and ball nest coordination can be adopted, and the angle between the pedal and the pushing rod can be readily adjusted. Accordingly, the pushing rod is always in the best state of being stressed, the frictional noise of the connection part is effectively eliminated.

Description

The connecting device of a kind of automatic clutch master cylinder and pedal

Technical field

The utility model relates to the connecting device of a kind of Clutch main cylinder and pedal, belongs to car accessory technical field, more is applicable to being connected of Clutch main cylinder and pedal in the manual car.

Background technology

At present, the Clutch main cylinder of car use both at home and abroad and the jointing of pedal are generally U-shaped fork or monolateral crank header structure, this U-shaped fork or monolateral crank head and Clutch main cylinder push rod generally are threaded connection together, and use metallic pin to be fixed on the clutch pedal wall, frequently step in the process of clutch pedal at chaufeur, because the phase mutual friction sends different sound easily, although on function without larger impact, the different sound that its course of action sends can affect driver's the sensation of driving.Along with the raising of people's quality of the life, the user requires more and more higher to the vibration of car and noise etc., therefore must improve this structure, to improve the vibration noise level of car load.

The utility model content

The utility model is in order to solve problems of the prior art, the connecting device of a kind of automatic clutch master cylinder and pedal is provided, and it is simple in structure, can effectively reduce the different sound that sends between pedal and the master cylinder, to reduce the vibrating noise of car load, improve driver's road sense.

For achieving the above object, the technical solution of the utility model is: the connecting device of a kind of automatic clutch master cylinder and pedal, comprise Clutch main cylinder and the push rod that is mated, and also comprise pedal, cooperate for the bulb ball-and-socket between described pedal and the push rod.

Preferably, cooperating by following structure between described pedal and the push rod realizes: be provided with a connector between described pedal and the push rod, an end of described connector cooperates with pedal is push-in, and the other end is socket arrangement, and it is that the bulb ball-and-socket cooperates with push rod.

Connecting device of the present utility model, when chaufeur is trampled clutch pedal, pedal is the zone of pedal wall metallic pin and the mutual friction of Clutch main cylinder jointing phase with the cooperation place of Clutch main cylinder, adopt above-mentioned bulb ball-and-socket to cooperate, can adjust at any time the angle between pedal and the push rod, so that push rod always is in best strained condition, effectively eliminated the friction noise of junction.

Description of drawings

Fig. 1 shows the structural representation of the utility model connecting device.

Fig. 2 is the cutaway view Amplified image at A-A place among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

With reference to figure 1, Fig. 2, the connecting device of a kind of automatic clutch master cylinder of the present utility model and pedal, the push rod 2 that comprises Clutch main cylinder 1 and be mated also comprises pedal (view does not provide), cooperates for the bulb ball-and-socket between described pedal and the push rod 2.

In the car running process, when chaufeur is trampled clutch pedal, pedal is the zone of pedal wall metallic pin and the mutual friction of Clutch main cylinder jointing phase with the cooperation place of Clutch main cylinder, adopt above-mentioned bulb ball-and-socket to cooperate, can adjust at any time the angle between pedal and the push rod, so that push rod always is in best strained condition, effectively eliminated the friction noise of junction.

Cooperating by following structure between described pedal and the push rod 2 realizes: be provided with a connector 3 between described pedal and the push rod 2, an end of described connector 3 cooperates with pedal is push-in, and the other end is socket arrangement, and it cooperates for the bulb ball-and-socket with push rod 2.

Connector 3 can adopt engineering plastics, also can adopt other materials known in the art, its push-in cooperation with pedal is technology known in the art, no longer specify at this, push-in fit structure has been realized simplification and the lightweight of clutch maneuvering system parts, has improved efficiency of assembling.The design of bulb socket arrangement, so that chaufeur is when trampling clutch pedal, connector 3 is done movement in a curve with pedal wall and push rod 2, can adjust at any time the angle of connector 3 and push rod 2, always make push rod 2 be in best strained condition; In order further to reduce noise, can coat grease in the ball-and-socket cooperation place, improved the vibration noise level of car load.

The utility model is by preferred embodiment having carried out detailed explanation.Yet, by to the studying carefully of preamble, concerning the variation of each embodiment with to increase also be apparent for one of ordinary skill in the art.Being intended that all these variations and increasing of applicant all dropped in the protection domain of the utility model claim.

Similar numbering refers to similar element in the whole text.For the purpose of clear, the situation that some line, layer, element, parts or feature are amplified may be arranged in the accompanying drawings.

Term used herein is only for to be illustrated specific embodiment, and it is not to be intended to the utility model is limited.Unless otherwise defined, all terms used herein (comprising technical term and scientific terminology) are all identical with the utility model one of ordinary skill in the art's understanding.

Claims (2)

1. the connecting device of an automatic clutch master cylinder and pedal comprises Clutch main cylinder and the push rod that is mated, and also comprises pedal, it is characterized in that: cooperate for the bulb ball-and-socket between described pedal and the push rod.

2. connecting device according to claim 1, it is characterized in that: cooperating by following structure between described pedal and the push rod realizes: be provided with a connector between described pedal and the push rod, one end of described connector cooperates with pedal is push-in, the other end is socket arrangement, and it is that the bulb ball-and-socket cooperates with push rod.
