Problems solved by technology

In the existing test method, the synchronizer assembly is installed on the synchronizer test bench for testing, but due to the friction resistance between the shift shaft and the upper cover, the friction resistance between the shift head and the guide block, and the friction between the shift shaft and the Due to the influence of the friction resistance between the shells, the force value generated by the balance spring of the synchronizer cannot be read correctly, which is not conducive to the analysis of the shifting performance of the synchronizer and the cause of the synchronizer's shifting.
[0003] At present, there is no test device for synchronizer balance springs in China, and foreign test devices have a long procurement cycle and are expensive

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0028] like figure 1 As shown, a synchronizer balance spring detection device includes a guide rail bracket, a three-claw bracket, a displacement sensor 2, a shift force sensor 3 and a host computer.

[0029] Wherein, the top of the guide rail bracket is provided with a linear guide rail assembly, and the linear guide rail assembly includes a fixed plate arranged horizontally. Set horizontally, two support plates at both ends are connected by rotation, one end of the linear guide rail 1 passes through one of the support plates, and the end of the linear guide rail 1 protruding from the support plate is connected with a handle, which is used to drive the linear guide rail 1 to rotate; The guide rail 1 is equipped with a moving guide block, the rotation of the linear guide rail 1 can make...

Abstract

The invention discloses a synchronizer balance spring detection device. A three-jaw chuck is adopted for fixing a synchronizer, the lower end of a shifting force sensor is connected with a shifting fork of the synchronizer, the upper end of the gear shifting force sensor is connected with a movable guide block, and a displacement sensor measures the displacement of the movable guide block; and themovable guide block is driven to move by rotating a linear guide rail, and then the shifting fork of the synchronizer is driven to move, so that a sliding sleeve compresses a balance spring through an ejector pin, the shifting force sensor detects the force value in the action process of the balance spring in real time, an upper computer analyzes the displacement amount and the force value of thebalance spring, and the force value provides a theoretical foundation for the improved synchronizer.

Description

technical field [0001] The invention relates to the technical field of synchronizer detection, in particular to a synchronizer balance spring detection device. Background technique [0002] The synchronizer balance spring will produce different force values ​​during the sliding process of the synchronizer sleeve, and its force value directly affects the shift feel of the synchronizer and whether the synchronizer is out of gear. In the existing test method, the synchronizer assembly is installed on the synchronizer test bench for testing, but due to the friction resistance between the shift shaft and the upper cover, the friction resistance between the shift head and the guide block, and the friction between the shift shaft and the Due to the influence of the friction resistance between the shells, the force value generated by the balance spring of the synchronizer cannot be read correctly, which is not conducive to the analysis of the shift performance of the synchronizer an...
