Abstract
The utility model relates to a clutch hub for an automatic gearbox. The clutch hub comprises a B1 clutch and a C4 clutch, wherein the B1 clutch comprises an inner hub of the B1 clutch and a support shaft for supporting the C4 clutch; the C4 clutch comprises an outer hub of the C4 clutch; an axial oil outlet is formed in the inner hub of the B1 clutch; a connection disc is connected with the B1 clutch and the C4 clutch; an outer ring of the connection disc is welded with the outer hub of the C4 clutch; the inner hub of the B1 clutch is welded with the outer hub of the C4 clutch; and a weld joint is formed among the welded parts of the connection disc, the outer hub of the C4 clutch and the inner hub of the B1 clutch. The clutch hub provided by the utility model can reduce accumulative errors and simplify a process, and is easy to process as the connection disc is formed by stamping. The connection disc is matched with the inner hub of the B1 clutch to form an oil holding channel so as to solve the problems of insufficient space arrangement for and difficult processing of a plurality of clutches of the conventional multi-speed gearbox, so that the clutch hub is simpler and more convenient to process and is suitable for batch production.
Description
Technical field
The utility model relates to a kind of clutch hub, is applicable to multi-speed automatic transmission, specifically, relates to a kind of clutch hub for automatic speed changer, belongs to the automatic transmission technical field.
Background technique
At present, in the design of multi-speed automatic transmission, need a plurality of controls of design in conjunction with the clutch of action, as shown in Figure 1, the outer hub 2 of C4 clutch welds together by land 4 with the interior hub 1 of B1 clutch, outer hub 2 welding of the outer ring of land 4 and C4 clutch, hub 1 welding in the inner ring of land 4 and the B1 clutch, hub 1 adopts the machining moulding in the B1 clutch, need to process pocket oil groove 7 on the end face of hub 1 in the B1 clutch, also need to process axial oil duct 6 and oil outlet radially 5 on the hub 1 in the B1 clutch, so that lubricant oil is by pocket oil groove 7, oil duct 6, the friction plate that oil outlet 5 lubricates in the B1 clutch hub.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem, and the outer hub 2 of C4 clutch passes through land 4 welding with the interior hub 1 of B1 clutch, forms two weld seams, complex process, and cumulative error is large; Oil duct 6 processing difficulties are not suitable for batch production.
The model utility content
The technical problems to be solved in the utility model is for above deficiency, a kind of clutch hub for automatic speed changer is provided, overcome that complex process in the prior art, cumulative error are large, processing difficulties, the defective that is not suitable for producing in batches, after adopting clutch hub of the present utility model, has the advantage that technique is simple, error is little, processing is simple, be fit to batch production.
For solving above technical problem, the utility model is by the following technical solutions: a kind of clutch hub for automatic speed changer, comprise B1 clutch, C4 clutch, the B1 clutch comprises hub and the back shaft that is used for supporting the C4 clutch in the B1 clutch, the C4 clutch comprises the outer hub of C4 clutch, the firm oil outlet that is provided with radially in the B1 clutch, be connected with land between B1 clutch, the C4 clutch, it is characterized in that: the outer hub welding of the outer ring of described land and C4 clutch, the inner ring of land and back shaft welding;
The outer hub welding of hub and C4 clutch in the B1 clutch, the weld of hub forms a weld seam in land, the outer hub of C4 clutch, the B1 clutch.
A kind of optimized project, described land cooperate formation pocket oil oil duct with hub in the B1 clutch, pocket oil oil duct is communicated with oil outlet.
After the utility model adopts above technological scheme, compared with prior art, have the following advantages: the outer hub welding of the outer ring of land and C4 clutch, the simultaneously outer hub welding of hub and C4 clutch in the B1 clutch, land, the outer hub of C4 clutch, the hub weld forms a weld seam in the B1 clutch, reduced cumulative error, simplified technique, the land impact briquetting, easily processing, land cooperate with hub in the B1 clutch and have formed pocket oil oil duct, have solved a plurality of clutch space layout deficiencies and unmanageable problem in traditional multi-gear gear-case design, process easylier, and be fit to batch production.
Below in conjunction with drawings and Examples the utility model is elaborated.
