Abstract
The utility model relates to a cylinder block structure of an automobile hydraulic release bearing assembly, which comprises a casing and a guide sleeve, wherein the guide sleeve made of metal via drawing molding, the casing is made of engineering plastic via integral injection molding, and simultaneously the guide sleeve used as a framework is molded with the casing when in injection molding so as to form an integral composite cylinder block structure. The cylinder block has compact structure and light weight, and sealing rings in various shapes and required to be used in a cylinder and guide sleeve split structure are removed, thereby avoiding potential risk of oil leakage and decompression caused by failure of sealing.
Description
Technical field
The utility model relates to a kind of bearing, especially relates to a kind of housing structure that is used for the clutch release bearing assembly between motor car engine and the gearbox.
Background technique
To mould the developing direction that Dai Gang is auto parts and components.The hydraulic pressure release bearing assembly is a new technology of automobile clutch piece-rate system, but owing to be subjected to the restriction of working space and gearbox one shaft diameter, the wall thickness of piston guide cover part often has only about 1.5mm in its plastic cylinder, therefore when design, all the cylinder body guiding partly is designed to metallic material tensioning member (guide sleeve), housing is engineering plastics (PA66+GF50) parts, the two composition body structure cylinder body.The two binding portion is set up the rubber seal of different shape and is tightened up part in case leak-stopping oil decompression.This structure not only part is many, the assembling difficulty, and also very easily because of sealing the unreliable leakage of oil decompression that causes, the Separating force deficiency makes clutch thoroughly not separate.
Summary of the invention
Technical problem to be solved in the utility model is the housing structure that a kind of automobile hydraulic release bearing assembly of improvement is provided at the present situation of prior art, not only compact structure is in light weight for it, and cancelled cylinder body and guide sleeve split structural design must not obsolete different shape seal ring, avoided because of the potential leakage of oil decompression risk of seal failure.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of housing structure of automobile hydraulic release bearing assembly, comprise housing and guide sleeve, its middle shell is an engineering plastics spare, guide sleeve is a metal stretching spare, it is characterized in that described housing adopts the integral molded plastic moulding, and in its injection moulding, described guide sleeve is injection-moulded in together, make described cylinder body form holistic composite cylinder body structure.
Compared with prior art, advantage of the present utility model is:
1, whole compound cylinder body substitutes the split assembly cylinder-body, thereby has avoided the potential leakage of oil decompression of split cylinder body to cause automobile clutch to separate halfway risk.
2, simplify the structure, saved sealing and tightened up part, overall structure is more compact.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the cylinder body of automobile hydraulic release bearing assembly of the present utility model, its guide sleeve 2 is a metal stretching spare, it with housing 1 injection moulding in.Housing 1 adopts the moulding of glass fibre reinforced nylon (PA66+GF50) integral molded plastic, which is provided with oil inlet hole 11, connects ring shaped oil passage 12.
During injection moulding, with guide sleeve 2 as skeleton, become housing 1 with the glass fibre reinforced nylon integral molded plastic, and in injection moulding, in guide sleeve 2 is wrapped in, and form holistic composite cylinder body structure, the housing structure of making thus is simple, compact, cancelled cylinder body and guide sleeve split structural design must not obsolete different shape seal ring, avoided because of the potential leakage of oil decompression risk of seal failure.
Claims (1)
1. the housing structure of an automobile hydraulic release bearing assembly, include the cylinder body of plastic casing and metal guide sleeve, it is characterized in that: described cylinder body is described guide sleeve to be injection-moulded in the holistic composite cylinder body structure that forms together in the integral molded plastic moulding by housing.
