Description

Technical Field

[0001] This invention belongs to the field of automotive powertrain logistics and transportation technology, and in particular, an automotive powertrain transfer platform. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] To improve production efficiency, automobile manufacturers, whether large-scale and well-established or emerging, all need to transport automotive powertrains. Traditionally, powertrain transport relies heavily on trolleys, which is inefficient, unsuitable for large-scale automobile production, and detrimental to cost and cycle savings. Therefore, current technologies have improved upon this method, moving away from the traditional trolley approach.

[0004] For example, Chinese utility model patent CN 209192647U discloses an automotive powertrain transfer bracket, specifically comprising a base and at least one set of positioning support components disposed on the base. The positioning support components include a transmission support column at the front, a first engine support column and a second engine support column in the middle, and a third engine support column and a fourth engine support column at the rear. The positions of the first, second, third, and fourth engine support columns are adapted to the support points on the engine. The transmission support column is detachably slidably connected to the base. This patent, by changing the support columns to a movable connection method, can meet the transfer requirements of different powertrains in different vehicle models.

[0005] However, the inventors discovered that although the existing technology has improved the trolley-based method for transporting traditional powertrains, some inconveniences still exist in its use: (1) The existing transfer platforms are not compatible with assembly line production. Since the advantages of rail production lines are obvious, the inability of transfer platforms to be compatible with rail production lines will cause great inconvenience and reduce production efficiency. For example, the aforementioned utility model patent does not have a structure that is compatible with rail production lines.

[0006] (2) The existing transfer platform is made of rigid material for supporting the powertrain, which can easily cause some damage to the vehicle powertrain.

[0007] (3) The existing transfer platform has a relatively simple support method. The support positions are generally multi-point support arranged in parallel. The contact area of ​​the support points is small, and the layout and setting of the support points are not scientific and flexible enough. Therefore, the effect and stability when supporting the powertrain need to be improved. For example, in the above-mentioned utility model patent, the support columns are set on the first, second and third crossbeams arranged in parallel. The support is actually each support column and the positioning protrusion set on the support column. Due to the small contact area, the overall stability of such support points is poor. Summary of the Invention

[0008] The purpose of this invention is to provide an automotive powertrain transfer platform suitable for rail-type production lines. It provides a triangular stable support structure for the engine and transmission, enhancing overall stability. Furthermore, the design of the contact surfaces between each support point and the engine, transmission, etc., not only increases the effective contact area but also facilitates fixing and support. All contact surfaces between the support points and the engine, transmission, etc., are made of polyurethane material, further protecting the structure of the engine, transmission, etc., from damage, thus solving the problems in the prior art.
