Problems solved by technology

However, some sensors used in the prior art are expensive, which increases the manufacturing cost. In addition, the sensor or the buzzer is placed in the friction plate, and it is necessary to reserve an installation position for the sensor or the buzzer when the friction plate is processed, or Secondary processing is carried out on the manufactured friction plate, which increases the difficulty and process of manufacturing the friction plate

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings. The words "upper", "lower", "left", "right" etc. used in this article to describe the orientation are based on the orientation shown in the drawings for the convenience of explanation. In the actual device, these Orientation may vary due to how the unit is placed. In this paper, "clutch disengagement process" refers to the process of the clutch from the engaged state to the disengaged state; "clutch engagement process" refers to the process of the clutch from the disengaged state to the engaged state; Stay engaged.

Abstract

The invention discloses a debugging-free multifunctional clutch booster, which increases a set of electrical control mechanism in parallel on the basis of a hydraulic control mechanism for realizing the diversity of the gear shifting process of the vehicle. The booster further comprises a boosting piston (2), a hydraulic piston (4) and a spacing post (16); wherein the boosting piston (2) and the hydraulic piston (4) form a split structure; the boosting piston (2) is fixedly connected with the spacing post (16); the spacing post (16) is arranged in an inner cavity of the hydraulic piston (4). When the electrical control mechanism is used for controlling, the boosting piston (2) drives the spacing post (16) to move in a certain limit (L1) of the hydraulic piston (4) without moving the hydraulic piston (4), so as to protect a clutch hydraulic system to the greatest extent. The booster can effectively judge the separation and reunion states of the clutch through an angular displacement sensor. The booster further comprises a clutch friction plate abrasion alarm device (32).

Description

technical field [0001] The present invention relates to a clutch booster, and more particularly to a pneumatic clutch booster that can be operated in two ways. Background technique [0002] Friction clutches are widely used in transmission systems of various vehicles. Up to now, the operation forms of friction clutches have become more and more diversified, mainly including electric and electronic control type with motor as the power source, electronic control hydraulic type with hydraulic pressure as power, and hydraulic control pneumatic type with air pressure as power. Among them, the pneumatic type has been used more and more due to its advantages of low cost, simple structure, and environmental protection, especially in medium and heavy commercial vehicles and large passenger vehicles with their own air source (air brake). Broad prospects. [0003] In the traditional pneumatic clutches that use air pressure as the power source to drive the clutch to separate and engag...
