Automobile clutch performance test device

Abstract

The invention discloses an automobile clutch performance test device applied to the technical field of automobile part tests. A clutch pedal on a test device cabinet of the automobile clutch performance test device is connected with a dash panel bracket, one end of a telescopic cylinder is movably connected with a mounting bracket, the other end of the telescopic cylinder is connected with a pedaltread of the clutch pedal, a separation execution support and a flywheel support are arranged on a rack base of a separation execution rack, a displacement sensor I and a force sensor I are arrangedbetween the telescopic cylinder and the pedal tread, and a force sensor II is arranged between a hydraulic separation bearing and a clutch. According to the device provided by the invention, the automobile clutch performance test device can accurately simulate the state of the whole automobile clutch system, can test the automobile clutch performance all the year round, provides reliable data support for product development and innovative design, and effectively improves the product quality.

Description

technical field [0001] The invention belongs to the technical field of auto parts testing, and more specifically relates to an auto clutch performance testing device. Background technique [0002] The performance of clutch characteristics of the whole vehicle mainly refers to the driver's operating perception when manipulating the clutch pedal. In all MT-type vehicles, the clutch operation cannot be avoided. It is necessary for the driver to step on the pedal to separate the driven disc of the clutch from the flywheel of the engine. And combined, the power can be cut off and input to ensure the normal start of the vehicle and smooth shifting. The clutch pedal force felt by the driver's left foot is mainly the maximum pedal force of the clutch system. Its source comes from the separation force of the working point of the clutch driven disc. When the system efficiency is converted to the clutch pedal, the clutch pedal force of the car is usually required to be between 85-110N...

AI Technical Summary

Problems solved by technology

[0003] At present, in the field of automobile manufacturing, due to the inability to intervene in the performance test of the clutch system in the early design and development stage, the vehicle test can only be carried out after the prototype car is released, which increases the project cycle and the cost of design changes; Disassembly and assembly bring a lot of inconvenience, the test cycle is also long, and the seasonality is relatively large, so the clutch performance test caused by temperature difference cannot be carried out at any time

At present, the common clutch performance test devices on the market use cylinders and hydraulic cylinders as the driving source, which are not accurate enough, have poor control accuracy, and cannot be verified for tem
