Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0030] Such as image 3 Shown is a partial sectional view of a differential gear structure in the prior art. Generally, in the bench test of a manual transmission, when the two ends of the differential case do not need to be connected to the half shaft, the two ends of the above-mentioned differential case are used to connect the half shaft. Figure 4 Sealing plugs shown, specifically can be located as image 3 The location indicated by the two arrows. The sealing plug can play a sealing role during the test to prevent the oil in the differential from leaking out, and can also rotate synchronously with the side gears in the differential without affecting the normal progress of the bench test.

[0031] The embodiment of the present invention is to p...

Abstract

The invention discloses a fixing device used in a transmission bench test. The fixing device comprises clamping parts and installing parts. The clamping parts are arranged on the outer sides of sealing plugs, are used for limiting movement of the sealing plugs in the direction of the axis of a differential mechanism and synchronously rotate along with the sealing plugs to play a role in fixing without affecting normal use of the sealing plugs; the installing parts play a role in fixing the clamping parts and can fix the clamping parts to other components except the differential mechanism; during the bench test, the sealing plugs are usually arranged at the positions, used for connecting half axles, at the two ends of a shell of the differential mechanism respectively and usually synchronously rotate along with half axle gears in the differential mechanism, so that the phenomena that the sealing plugs are loosened and drop can easily occur, potential safety hazards can even be caused, but the sealing plug fixing device well solves the problems.

Description

technical field [0001] The invention relates to an automobile transmission test equipment, in particular to a fixing device used in a transmission bench test. Background technique [0002] In the manual transmission bench test, when some tests are carried out, the two ends of the differential do not need to be connected to the half shaft, and the two ends of the differential need to be sealed by the corresponding sealing plugs. During the test, the sealing plug and the differential are rotated at the same time, and the sealing plug is easy to loosen and fall off during the rotation, causing oil splash and personal injury. Therefore, in order to ensure the particularity of the seal and the safety of the test process during the test of different transmissions, it is necessary to study the fixing of the above-mentioned sealing plug. Contents of the invention [0003] The purpose of the present invention is to provide a fixing device for the differential sealing plug used in ...
