Description

clutch cable

technical field

The utility model belongs to automobile clutch components, in particular to a clutch cable for a mechanical clutch.

Background technique

At present, the separation control mechanism of domestic clutch is mainly based on mechanical clutch separation cable and hydraulic clutch control. The structure of the mechanical clutch release cable is simple and cheap. The clutch release cable is a wire rope. One end of the wire rope is connected to the pedal of the driver of the car, and the other end is connected to the clutch release arm of the car. The inner position is accurate, a support is fixed on the car body, and the steel wire rope passes through the hole on the support. The structure of the entire mechanical clutch cable is simple and the price is cheap; but the mechanical clutch release cable is mainly composed of a thin steel The rope transmits power, and its power is transmitted in a 1:1 manner, resulting in excessive force on the clutch pedal.

The disadvantages of domestic clutches are: the operation of the clutch is laborious, and the operation of the whole clutch mechanism is relatively stiff.

Utility model content

The purpose of the utility model is to provide a labor-saving wheel clutch separation cable, the clutch is easy to operate, and the driving comfort is improved.

In order to achieve the above object, a clutch cable described in the utility model includes a pedal cable and a support, the key of which is that a pulley positioning box is fixed on the support, and a pulley groove and a pulley groove are installed in the pulley positioning box. A movable pulley, wherein the pulley groove is fixed in the pulley positioning box, the main shaft of the movable pulley is vertically inserted into the pulley groove, the main shaft is fixed with a separation cable, and the separation cable stretches out from one end of the pulley positioning box; The pedal cable extends from the other end of the pulley positioning box, and is fixed on the pulley positioning box after going around the movable pulley.

The device is simple in structure, compact, small in size and cheap in price. It uses the traditional mechanical clutch cable as the design basis, and a movable pulley is designed at the support of the separation cable as a labor-saving mechanism. The connecting hooks of the pedal cable and the separation cable are respectively Connects with pedal hook and clutch release arm hook.

The main friction of the pulley transmission is sliding and rolling, which reduces the friction coefficient, reduces the mechanical efficiency loss of the entire pulley mechanism, improves the force transmission efficiency of the clutch cable, and does not have the traditional mechanical clutch cable operation. It is easy to get up and brings driving comfort to the driver.

The remarkable effect of the utility model is that the structure is simple and compact, the size is small, the price is cheap, the force transmission efficiency of the clutch cable can be improved, the operation is soft, and the driving comfort is brought to the driver.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figures 1 and 2: a clutch cable, including a pedal cable 1 and a support 2, the key is that a pulley positioning box 3 is fixed on the support 2, and a pulley is installed in the pulley positioning box 3 Groove 4 and movable pulley 5, wherein pulley groove 4 is fixed in the described pulley positioning box 3, the main shaft 5a of described movable pulley 5 is vertically inserted in the pulley groove 4, and separation cable 1' is fixed on the described main shaft 5a, and this separation pulley The cable 1' protrudes from one end of the pulley positioning box 3; the pedal cable 1 extends from the other end of the pulley positioning box 3, and is fixed on the pulley positioning box 3 after going around the movable pulley 5 superior.

The device is simple in structure, compact, small in size and cheap in price. It uses the traditional mechanical clutch cable as the design basis, and a movable pulley 5 is designed at the separation cable support 2 as a labor-saving mechanism. The pedal cable 1 and the separation cable 1 The connecting hook of ' is connected with the pedal hook 6 and the clutch release arm hook 7 respectively.

It works as follows: .

Fix the support 2 on the car body, install the pulley positioning box 3 on the support 2, design the pulley block as a labor-saving mechanism, connect the pedal cable 1 and the separation cable 1' to the pedal hook and the clutch release arm hook respectively . The pedal power is transmitted in the form of 1:N, and the size of the pedal force can be adjusted according to the needs; moreover, the clutch cable of the movable pulley block is softly engaged, without the rigid feeling of the traditional mechanical clutch cable, which brings the driver a sense of driving comfort. comfortability.
